Hon. Hark Novitch Acting Commissioner Food and Drug Administration 5600 Fishers Lane Rockville, MD 20460 /-1 , Petition for labeling of warning of the hazardous effects produced by asbestos in cosmetic talc. The purpose of this petition is to request a labeling of warning as well as a detailed list of components of the commercial cosmetic talcs. Because of its geological formation cosmetic talc may contain significant amounts of asbestos particles producing hazardous effects by its continuous use. Since it is a cosmetic article its production and commercialization is regulated by the Food, Drug and Cosmetic Act. I am a graduate student of Marine Environmental Sciences and I am deeply concerned by the toxic effects produced by the constant and periodic use of talc by the public, specially children. Because commercial talc deposits consist of natural admixtures of mineral, a number of mineralogically different materials have been used as commercial talc. Asbestos is a generic term for a variety of natural minerals which have the ability to be separated in filaments ( 1 Since the mining of talc rock almost invariably includes the mining of asbestos as well, the asbestos contaminant is carried over into the consumer product and thus introduces the risk of asbestos disease (2 ). Knowledge of diseases associeted with the use of asbestos apparen tly dates back 2000 years and detailed medical reports with the classificaxi-on of asbestos as a harmful substance began about 1900 (3 ). It has been widely proven that the inhalation of asbestos is the direct cause of hemolysis (^,5*6 ) and diseases such as asbestosis, bronchial cancer, pleural mesothelioma and peritoneal mesothelioma (3 ^ 5 ? 3 ,9 1 ' Asbestosis is a diffuse pulmonary fibrosis initiated by the inha lation of asbestos ^articles. The particles above 10 microns are fil tered in the passage through the nose and trachea to the lungs, but the inhaled air reaching the respiratory bronchioles and alveoli contains thesmall-sised particles (1 - 5 microns) that would tend to deposit (-3)* Timbrell found that the fibres of 3 microns diameter are the thickness that are likely to be deposited in the alveolar regions (11), and the fibres with a smaller diameter (less than 3 microns) -especially those below 1 micron- are carcinogenic if introduced into the pleural or peritoneal cavity (9). Neither the "clearming" (mucociliatory escalator) nor the inmunological system (macrophages) are able to expel or destroy these particles (3^12). Then fibroblasts in an irreversible process produce the collagen, which forms the characteristic fibrosis of the asbestosis (5)these can lead torespiratory disability (5) and death may result from pul monary hypertension and cardiac failure (3). About 50% of the asbestosis patients may develop carcinoma, such as mesothelioma, a diffusive cancer that rapidly spreads over the surface of the lungs, abdominal organs and heart (3). The exposure to talc dust has been shown to produce lung scarring, termed talcosis, and asbestos bodies are observed in lung tissues of individuals who die of talcosis (1^). The "fibrous" talc appear to be more pathogenic than "platy" talc, so this disease is due to asbestos rather than talc (16-,15). Timbrell found that due to their fibrous shape, asbestos particles remain airborne longer and show less ten dency to sediment than granular microparticles of equivalent v/eight (16), this physical factor will increase the asbestos exposure of a person in an environment where talc has been recently used. The asbestos diseases are due to occupational and non-occupational exposures (8,17); only ^0.8% of the mesotheliomas found in patients of London Hospital from 1917 to 1 9 6 ^ were due to occupational expo sures (8). Every body is affected by this air pollution, as has been demonstrated in lung studies done in France (18) and New York City (19 Permissible occupational exposure limits exist in several countries, in the USA, the Occupational Safety and Health Administration (OSHA) proposed in 19 75 a non-occupational exposure limit of 5 fibers/ml for a period of 1 5 minutes (9 ). Several mineralogical analyses have been made on commercial talc, and all the samples contained asbestosform mineral impurities (5,20). Snider-et al in I972 found that in eighteen commercial talcum powders, the asbestos impurities varied in amounts from b to k6% meanwile the labels listed no impurities (20). In 51 common talcs analysed at Mount "Sinai Hospital, the asbestos content ranged as high as 87# (5) The purity of any commercially available talc in the U.S. is related to both the nature of the original talc deposit and the extent to v/hich the rock is upgraded to eliminate contaminant minerals. As the percentage of asbestos impurities is not related to price (20), this labeling will probably force the producers to control their talc com position to maintain their revenues. There have been many lawsuits relating to the health aspects of asbestos, and the causes of action in product liability lawsuits generally involve the operative allegations: -Failure to warn: thus the consumer was unaware of the danger. -Failure to test: by the producers to test their products to pro perly ascertain its hazard, risk and dangers. -Failure to remove: by the producers to stop selling, or remedy (make safe) the asbestos product (3)* Warning of the health risks of exposure to asbestos has been recommended as a measure to be taken within the European Communities in 197?, and stated: "Asbestos containing products should be clearly labelled" (9)* The Food, Drug and Cosmetic Act is clear about these facts: "If an article is alleged to be misbranded because the labe ling is misleading, then in determining whether the labeling is misleading there shall be taken into account (among other, things)...the extent to which the labeling fails to reveal facts material in light of such representations or material with respect to consequences which may result from the use prescribed in the labeling thereof or under the conditions of use as are customary or usual". (21 U3C5 i 321.n) "A cosmetic shall be deemed to be misbranded- (b)If in package form unless it bears a label containing (2) an accurate state ment of the quantity of the contents in term of weight, measu re, or numerical count." (21 U3C3 362) "A cosmetic shall be deemed to be adulterated- (a)If it bears or contains any poisonous or deleterious substance which may -render it injurious to users under the conditions of use pres cribed in the labeling thereof, or under such conditions of use as are customary or usual." (21 U3C3 361) Taking into account the widespread use of cosmetic talc, v/hich start at birth (mostly used in the first years of life) and continues in a great number of people as a periodic exposure throughout their lifespan I address this petition to request the obligatory establishment of tables of quality (asbestos particle size) quantity (proportion of impurities) of components as well as a label of warning of the hazardou effects produced by asbestos with the continuous use of cosmetic talc. Respectfully submitted, November 8 ,1 9 8 3 Philippe Douillet 1 Holyoke Lane Stony Brook, NY. 11790 (516) 751-5350 Ref erences 1.

Technical support for QRAC's asbestos risk assessment. QRAC In fig. 1 we have plotted on a log-log scale Selikoff's original mesothelioma incidence data vs. years since first exposure to asbestos. Incidence is defined as number of mesotheliomas/man-years exposure. The data do not seem to fit a single straight line. Uncertainties of exposure in the early part of the century and the general decline in intensity of asbestos exposure after World War II are possible sources of error. For these reasons, as well as general lack of fit of both recent data and distant past data, Peto recommended use of a more homogeneous subset of workers for quantitative purposes, namely those workers first exposed between 1922 and 1946 [8]. It can be inferred from Selikoff's report that this subset consists of about 4800 workers. Peto reports 180 mesotheliomas (3.751) among this subgroup out of a total of 236 mesotheliomas for all 17,800 workers followed from 1967 until about 1978 or 1979. Note that Selikoff only reported 175 mesotheliomas total; however, his reported follow-up period was also shorter (1967-1976). Plotting Peto's homogeneous 1922-46 cohort subset, we see that 3^1 bt nicely fits the data (expressed as a straight line on log-log 21 paper with a slope of 3.1). We also see that b(t-10) * nicely fits the data (with a different value for the constant b) and may be a reasonable vay of looking at mesotheliomas since the time lag from mesothelioma induction to death is not zero. The time of mesothelioma induction is not even a well defined concept and may be intimately entertained with the concept of stage definition in, for example, a multistage cancer process. Nevertheless, both these model fits assume mesothelioma to be a nonincidental tumor (i.e., a life table where incidence is the ratio #tumor bearers/Isurvivors, re-expressed in man-years, per time interval). If we assume mesothelioma annual incidence to be better approximated by a prevalence or incidental definition, (#tumor bearers/#dead in interval), 1.64 then bt seems to be a rough though not very tight fit to the original Selikoff data. Peto's reported 1922-1946 data set does not easily allow determination of a prevalence fit. However, since the prevalence denominator is defined in terms of deaths per time interval rather than the much larger number of survivors to date, the first 2,271 deaths (12.72 of 17,800 workers) reported by Selikoff are very heavily weighted with the 1922-1946 cohort used exclusively in the two nonincidental curve fits above. Therefore comparisons of slightly different cohort subsets may still be useful. We estimate that the average time since first exposure for the Peto subset (1922-1946 first exposure) is about 37 years (Peto's 1978 follow-up) or 35 years (Selikoff's 1976 follow-up). This compares to 25 years average time since first exposure usually reported for all 17,800 workers. We also make the assumption that workers ceased exposure on average 3 years before death. QRAC - 3- 3.1 Method 1: based upon fitting bt * (nonincidental analysis) to a 1922-1946 cohort of the Selikoff, et. al. data. A reasonably simple nay to estimate the median life (ML) risk to median survival age 77 (in 1979) for humans exposed 2 yrs. to talcum powder during infancy is given by the product of the following terms: (a) (77 yrs. since first exposure for infants/37 yrs. since first exposure for 1922-46 cohort as of 1978*)^'^ 9.70. (b) (2 yr. infant exposure duration/34 yrs. approx, worker exposure duration for 1922-1946 worker cohort) * .059. (c) (infant/worker) yearly exposure ratio * 0.3 x 10 (d) 1922-1946 cohort cumulative mesothelioma response of 3.75% (180 mesotheliomas/4,800 cohort members). This product yields a median life risk of --8 = 0.64 x 10 2.1 Method 2: based upon b(t-10) * (delayed observation or time lagged nonincidental analysis). Note that to estimate real mesothelioma incidence (time of mesothelioma induction - the last stage of the multistage cancer process) at age x, the worker must be assumed to have been autopsied or surgically inspected at some average age, say x+10. Thus, assumming the worker stops exposure 3 years before death, the component relative and absolute risk factors for incidence at age 77 now are the following: (a) ((87 yrs.-10 yrs.)/(37 yrs.-10 yrs.)^`* = 9.03. (b) (2 yr. infant exposure duration/(37-10) yr. worker exposure duration) * .074. (c) (infant/worker) exposure rate ratio = 0.3 x 10 (d) 3.75% mesothelioma response in 1922-1946 cohort Thus = 0.75 x 10-8 . 1.64 Method 3: based upon bt ' (prevalence or incidental analysis): The relative and absolute risk product factors are: (a) (77 yrs. since first exposure for infant/35 yrs. since first exposure for the 2,271 deaths to 1 9 7 6 ) - 3.64. (b) (2 yr. infant exposure/34 yr. ave. worker exposure duration for 2,271 deaths to 1976) = .059. (c) (infant/worker) exposure rate ratio = 0.3 x 10 (d) 7.7% mesothelioma cumulative prevalence to 1976 (175 mesotheliomas/2,271 deaths). Thus - 0.50 x 10"8. Method 4 : based upon bt 3.'1 (nonincidental analysis) and a first stage effect in a generalized multistage process, k-1 We assume that bt fits the time-response data of a nonincidental tumor and is consistent with a first-stage-only effect in a generalized multistage process (with K stages), where biological time t starts at age of first exposure and continues until death [9]. Although this is not precisely true for the 1922-46 asbestos worker cohort, it appears to be approximately true. Moreover the time lag from cessation of exposure to end of followup (1976 or 1978 ) is assumed to be small compared to total duration of exposure (i.e. , exposure duration is a large fraction of time since first exposure). However, the exposure duration for Infants is very small compared to median lifespan. Thus, while we fit k-1 worker yearly incidence data to bt we should extrapolate yearly K-1 incidence (I) for exposed infants using the expression I *= b(t K-- 1 (t-d) ) for a K stage multistage process with duration of exposure d and time since first exposure t [9]. QRAC - 5- Nov K-1 " 3.1 from Fig. 1 and b can be written as the product of constant and f where f is the time adjusted yearly dose of asbestos fibers in ml-yrs. is a constant dependent upon the type and dimen sions of the asbestos. Since f * 3.43 f/ml-yr. (15 ave. f/ml in workplace (1922-1946) x 8 hrs./24 hrs. x 5 days/7 days x 50 wks/52 wks) for the Selikoff study, can be computed from the plot of I " K^f t3 1 -4 in Fig. 1. At t = 20 yrs, I e 5.6 x 10 , implying that the InK * In m (5.6 x 10~4)-ln(3.43)-3.1(ln 20) = -7.49-1.23-9.29-- 18.01. Thus = 1.51 x 10--8 (same as Peto obtains). Continuing, I = K f(t^ *-(t-d)^ *) * R ft^ ^(l-(l-d/t)^ *) which roughly mm K-l K^ft (d/t)(K-l) for d much less than t (using Taylor expansions). K-2 Thus yearly incidence is approximately I"R fd(K-l)t . Integrating m (without correcting for decreasing survival) over a total of T years K-l yields a cumulative incidence of about I * K fdT . If d = 2 yrs. cm infant exposure duration, T = 77 yrs., K-l = 3.1, f = 3.43 f/ml-yr. for worker x 0.3 x 10 ^ (infant/worker exposure ratio) = 1.03 x 10 ^ f/ml-yr., and Km = 1.51 x 10^, then Ic = 2.2x10 However, this figure assumes no mortality from competing causes of death and does not even adjust for the effect of previous mesothelioma related deaths. Factoring in a standard population age-specific mortal ity or corresponding survival function Into the above integral would --8 --8 yield a median life risk of about 75% of 2.2x10 or m l K 6 x l This correction for survival can vary depending upon the limits of integration and what functional forms are under the integral, but for median life risk estimates the correction ranges from 1.0 down to .5 at worst. He also note that Integrating I out to 100 yrs. of life with QRAC - 6- respect to a standard mortality curve should yield approximately the game risk as cumulative incidence to median age 77 yrs. without any mortality adjustments. These approximately cancelling effects of two mathematical refinements may support the utility of using the median lifespan in simple calculations. Comments on the 4 Mesothelioma extrapolation methods: First and most importantly, it should be noted that the first 3 methods yield virtually identical median lifespan risks for babies --8 exposed to talc for 2 years (.5-.75x10 ). Thus many of the debates over the "correct model" appear somewhat superfluous. In particular heated debates over whether mesothelioma rates follow given high or low powers of time appear to be superfluous since the power of time is compenstingly related to other poorly defined and difficult to measure conceptual model parameters (e.g., tumor stage initiation and consequent time lag to clinical detection or death, and context of tumor observation (incidental or nonincidental)). Furthermore, small perturbations of the rough estimates of worker exposure or the power of time (K) have only a small effect on the overall.risk. All the above models appear to be reasonable summary descriptors of the observable data and result in simple extrapolatory tools for the given problem of inferring median lifetime risk from Infant exposure. One can always make method 4 computationally more difficult if one avoids use of the approximations. A second observation Is that the rough mutual agreement of the results of the 4 extrapolation methods does not necessarily Imply that QRAC - 7- the obtained excess median life risk is accurate even if the infant and worker exposure were to the same type and dimension of asbestos fiber. For example, none of the four models take into account the possibility that accumulated dose rather than yearly dose rate might more accurately reflect the biological burden of asbestos due* for example* to its ability to reside in vivo in the lung, pleural or peritoneal lining for years without being excreted (although encystment may be possible). Hote also that we did not define dose on a mg/kg body weight basis. Although, we prefer such a definition for routine compounds that are ingested and metabolized, ve strongly suspect that routine approach to be inappropriate for asbestos. In addition, all A methods assume linearity in response vs. dose at all dose levels. However, we have virtually no reliable dose response data from any of the epidemiological studies. Furthermore, some investigators have suggested that the nonconstant accumulated asbestos dose may be as conceptually consistent with a late stage multistage carcinogenic process as the more usually defined yearly asbestos dose rate appears to be consistent with a first stage Armitage-Doll multistage process [9]. Although the theory and computa tions are more complicated for nonconstant exposures, it does appear that median life risks from infant exposure to asbestos affecting only a late stage in the carcinogenic process will generally result in much smaller risks than those calculated above for a first-stage-only effect in the carcinogenic process. Our third observation which we have just hinted at is that method 4 above (the first-stage-only effect in a multistage model) may be just another way of implementing method 1, but just slightly more computation ally difficult and having a slightly higher risk, partially because it substitutes a theoretical risk integration against the current (1979) U.S. population's standard survival function for the implicitly observ able but poorer asbestos worker's cumulative survival of an earlier era in a more toxic environment. For example, the method 4 risk is about 2.6 times greater than the average risk of methods 1-3. There are probably other reasons for this 2.6 fold increase in risk over methods 1-3. However, since even partial intervention of asbestos fibers at later stages of the carcinogenic process in the Armitage-Doll multistage model imply lower overall risks, we prefer the simpler methods 1-3 at this moment to the more complicated multistage models whose proper application with respect to the stage or stages affected is still very much in doubt. In general, we do not put a lot of faith in mechanical use of sophisticated but unverifiable models, but we will occasionally refer to them as in method 4 where we can suggest implicit and perhaps elucidative connections to apparently more humble and simpler procedures. QRAC - 9- Summary: All four mathematical methods of modelling the nonlinear mesothelioma response data from the Selikoff study indicate a lifetime added human risk to infants exposed 2 years to talc powdering of at most --8 about 10 risk, and quite probably far less risk, if for example, asbestos intervenes in the carcinogenic process at a later stage than the first stage which was assumed in method 4 for the Armitage-Doll multistage process.

FACTS Durinq the early 1 9 7 0 's FDA became concerned that significant amounts of asbestiform minerals may be present in cosmetic talc. The agency had received reports of cosmetic talc beinq contaminated with high levels of asbestiform minerals. However, at that time the analytical procedures for determining asbestos in talc were not fully developed and most of the analytical work was con duc te d without scientific agreement as to which methods were suited for the id entification of asbestiform minerals in talc. FDA then considered all analytical results to be of questionable reliability. As a result, the agency could not assess either the accuracy of the reported results or the extent of the presence of asb es tiform minerals in cosmetic talc then in the marketplace. FDA made the reports public and requested assistance from the affected industry in developing acceptable analytical procedures. Subsequently, many cosmetic manufacturers bepan to analyze talc for asbestiform minerals as part of their quality control proqrams and talc suppliers began to sell higher purity talcs to the cosmetics industry. Bv 191 6 asbestos analytical methodol ogy was sufficiently developed that the Cosmetic, Toiletry and Fraorance Association (CTFA) could issue a specifi ca tio n for cosmetic talc that required such talc to be free of fibrous amphibole (e.g., asbestos in the form of asbestiform tremolite) by a CTFA method of analysis which was capable of detecting 0.5? of amphibole asbestos. This sp ec ifi c at io n contri buted to the continued improvement of cosmetic talc quality. 1IFD H ismitw o rn a rr-iio ^ SURNAME ' _ E 3 L _ OFFICE ~w ~ or 't / 'f / i * SURNAME /h ^ DATE OFFICE JIM SURNAME DATE- AND HUMAN SERVICES .'-V v -a' u'LtTrM'*:^<aYk-&f>yZh: . FDA sur ve ill an ce activities that were c o n du c t e d In the l a t t e r ___ por tion of the 1970'3 showed that the quality of cosmetic talc h ad 8 Igni f ic an 11y improved, and that even when asbestos was/-;;.:-'; present, the levels were so low that no health hazard existed, ;> Our scientists recently reviewed data from these surveillance act ivities and concluded that the risk from a worst -c ase estimate from cosmeti c exposure would be less than the risk from environmental background levels of asbestos (nonoccupational exposure) over a lifetime (Tab R). - On November 8, 1983, Mr. Philippe Douillet s u bm i t t ed e petition (Tab C-Docket No. 83P-0404) requesting that cosmetic talc be labeled with an asbestos warning statement and information on asbestos particle size and the proportion of talc impurities in the product. The petition contends that co smetic talc is c o n t a m i n a t e d with asbestos and that this c ontam inati on presents an inhal at ion hazard. The p e t i t i o n 's s u bs t a nt iat io n of this co nte n t i o n consisted only of twenty references. None of the refer enc es was recent enough to indicate that co smetic talc co n tai ns any asbestiform minerals at this time. DISCUSSION Because Hr. Douillet's petition contains no su bs tantiation of a health hazard attributable to asbestos in cosmetic talc at this time, we have drafted a letter of denial (Tab A) for your aDproval . The draft letter of denial explains why we do not believe asbestos co nta mination problems exist at this time. We did not include the recent scientific evaluation of asbestos risk as an enclosure for the draft letter but we plan to forward the ev alu ati on to the Dockets Management Branch upon issuance of the letter of denial . RECOMMENDATION It is re c om m en de d that-the draft letter of denial concerning asbestos warning s ta te men ts on cosmetic talc be approved and issued. 1.
