FOOD AND DRUG ADMINISTRATION I V^ ; Dr. Robert M. Schaffner, Director Office of Technology (BF-400) 1973 >M : Dr. Alfred Weissler, Acting Director Division of Color Technology (BF-430) IJECT: Summary and Comments on Prof. Lewin's Analytical Results for Asbestos in Talc 1. The purposes of this memorandum are to present a summary of the analytical results for asbestos in Cosmetic talcum-type powders obtained by Prof. Seymour Z. Lewin of New York University in his role of consult ant to FDA; to compare his results with those obtained by other labora tories on some of the same samples; and to make some comments on the gen eral question of suitable techniques for the analysis of asbestos in talc. 2. 1 asked Dr. Lewin in December 1971 to undertake asbestos analyses in 100 samples of cosmetic powders; the scope was expanded on two subsequent occasions, to include a total of 195 samples. I chose Dr. Lewin for this work because he is an internationally-recognized expert on mineralogical chemistry and because he is a member of the academic community and there fore likely to be impartial in a confrontation between industry and government. Furthermore, his competence had previously been recognized by industry (by virtue of their own use of him as a consultant) which appeared to confer a desirable immunity against possible industry attacks on the validity of the results. 3. Dr. Lewin's findings are shown in Table I; the key to the identities of the numbered samples is given in Table IV. Please note also the ex planatory comments in Dr. Lewin*s memo of July 10, 1973, which is an Attachment to Table I. No varieties of asbestos other than chrysotile (a serpentine) or tremolite (an amphibole) were found by Dr. Lewin in the 195 samples which he examined. As shown in Table I, Dr. Lewin found definite indications of chrysotile in 17 of the samples (many of these also had tremolite) and definite indications of tremolite but not chryso tile in an additional 18 of the samples. These results were obtained primarily by means of X-Ray diffraction, supplemented in some cases by optical microscopy and other techniques. However, Dr. Lewin points out on page 2, paragraph 1 of the Table I Attachment that the chrysotile he has identified in commercial products shows several significant dif ferences from "classical" chrysotile: in the location of its X-Ray dif fraction peaks, in its appearance under the microscope, in its reactivity toward dilute acid, and in its behavior with respect to differential thermal analysis. HHS00000197 Page 2 - Dr. Robert M. Schaffner 4. In Table II, I have compared Dr. Lewin's results for tremolite with those obtained for some of the same samples at FDA. (by means of optical m(ibcyromsecaonpsy)ofaXn-dRaaty the Pfizer Minerals, Pigments, and Metals diffraction). This comparison, which was Division undertaken in order to obtain additional information on the samples, shows good semi-quantitative agreement among the three laboratories. Whatever quantitative differences exist in the amounts of tremolite found can be understood readily on the basis of such factors as (a) preferred orien tation of plates and fibers in the packing of the X-Ray diffraction sample, and (b) inhomogeneities in sample composition, caused for example by air lutriation within the container when it is shaken. 5. In Table III, I have compared Dr. Lewin's results for chrysotile with those obtained for some of the same samples by four other labora tories; the additional two laboratories included in this part of the study are Columbia Scientific Industries of Austin, Texas (who sell the Stone apparatus for differential thermal analysis) and the Health Protection Branch of the Department of National Health and Welfare of the Canadian government in Ottawa. The agreement of results from dif ferent laboratories is much less satisfactory for chrysotile than that discussed above for tremolite. For example, samples 8S and 163 were found by Dr. Lewin to contain 57 and 107 of chrysotile, respectively, but chrysotile was not found in these samples by the other laboratories. Also, a preliminary finding of chrysotile in a sample of Johnson and Johnson Shower to Shower Body Powder has been disputed by the company, which claimed that their own analyses by several different techniques fail to show the presence of chrysotile. The explanation for these differences is attributable largely to Dr. Lewin's inclusion in the term "chrysotile" of mineral species which show significant differences from classical chrysotile, as discussed in paragraph 3 above. 6. The difficulties involved in analyzing talc and other samples for small amounts of asbestos have been pointed out by many investigators. It is not surprising that the results of different laboratories disagree sometimes, especially in the presence of transitional or altered minera logies! species. Moreover, with regard to the two varieties of asbestos of concern here, it is unfortunate that the one which is a clear inhala tion hazard to man, namely chrysotile, poses an intrinsically more dif ficult analytical problem than the other, tremolite, which has not yet been shown to present a biological hazard. This is due in part to the less prominent X-ray diffraction peaks of chrysotile and to the fact that the fibers are often too small to be seen in the optical microscope. 7. In connection with a proposed new regulation on the safety of cos metic talcum powders, we face the problem of specifying an analytical test for asbestos which must be satisfied by the powders if they are not to be considerated adulterated. On the basis of information available at present, I recommend consideration of the following procedure. The powders shall be examined first by X-ray diffraction, which has a sensi tivity of the order of 17. for chrysotile and somewhat greater sensitivity HHS00000198 Page 3 - Dr. Robert M. Schaffner for tremolite. If either species is found, confirmation that the species is present in fiber form is to be obtained by optical microscopy and elec tron microscopy. This is necessary because tremolite is known to occur in a non-fibrous fora, and the X-ray diffraction pattern of chrysotile is the same as that of antigorite, a non-fibrous form of the same min eral. The sample is considered adulterated if the presence of fibrous tremolite or chrysotile is shown by the above procedure. An alternative procedure^ based solely on optical microscopy (which is a less expensive and more widely available technique) might be proposed. However, the difficulty with optical microscopy alone is that it may completely miss the presence of chrysotile if the fibers are submicroscopiCj which may well be the case in finely-milled talc; X-ray diffraction is not subject to this source of error.

Z. Lewin Chemistry Department, New York University Re: Determination of Asbestos Contents of Commercial Talcum Powders. This will serve to summarize the main points of our discussion on this date of July 10, 1973 with respect to the factors involved in the detection and estimation of asbestos in talc, and the status of the tabulation of results of the analyses of commercially avail able consumer products containing talcum powder. My research group has been engaged in studies of talc and its accessory minerals continuously since July 1971, and we are continuing to work in this field. We have undertaken to investigate the follow ing problems: A, Tabulation of the x-ray diffraction data for talc and all solid phases (whether naturally occurring, or added in the course of processing) encountered with talc in mineral, industrial, cosmetic and pharmaceutical products. B. Elucidation of the x-ray diffraction spectrum (i.e., precise locations and relative intensities of peaks and variability thereof) of ehrysotile. Assignment of the diffraction peaks to the crystal planes responsible for them, and interpretation in terms of crystallogrE phy of the effects of grinding, orientation, and sample preparation. C,, Investigation of the chemical properties of ehrysotile, antigorite, chlorite, tremolite, and talc; specifically, measurement of the rates of hydrolytic and ion replacement reactions. D. Microscopy, both optical and electron, of ehrysotile and of talcs containing various accessory minerals, including ehrysotile and- tremolite. E. Measurement of the degree of enrichment, due to air elutriation, of asbestos in the lightest fractions of the dust from commercial HHS00000206 ffi 2. - F,, Development of a method based on the combination of x-ray diffraction, chemical reactivity, and microscopy for the estimation of the chrysbtile and tremolite contents of consumer products (these two being the only asbestiforai minerals encountered in all the American products examined so.far, with only one possible exception), and application of the method to the analysis of about 200 standard store-purchased specimens. G. Investigation of alternative analytical methods, viz., diff erential thermal analysis and density gradient centrifugation, as alternative or supportive techniques. Our results to date support the following conclusions: 1. The ehrysotile that is found in commercial talcs is generally different in significant respects from the ehrysotile that occurs as massive, fibrous growths in veins in serpentine rocks. That is, the for mer has diffraction peaks that may differ from the latter by as much as 0.2 A (at 7 .3 A); it is more reactive toward dilute acids; it shows a different appearance under the microscope; and its DTA endo- therms and exotherm are shifted relative to those of the latter (and apparently diminished). 2. The presence of ehrysotile as a minor constituent in talc may he established with reasonable certainty on the basis of (a) the presence of x-ray diffraction peaks in the vicinity of 7*23 to 7.^3 A and 3-59 to 3*65 A, (b) the pronounced weakening or complete disappear ance of these peaks upon treatment-up on .tn&atgent- of the specimen with 1 M HC1 at 80C for 1 hour, (c) the presence of fiber bundles of visible size under 250X or higher magnification in the optical micro scope which show a refractive index of about 1.54 (these fiber bundles may be short and straight, and may he coated with a bumpy encrustation of Mgcfo^, or may be embedded in talc or other particles), and (d) the presence of fibers under the electron microscope which yield an electror diffraction pattern that corresponds in d-values to those found in the x-ray diffraction pattern (these fibers typically do not have a hollow central capillary running through them). 3 . The concentration of ehrysotile in a talc may he estimated by measuring the area under the x-ray diffraction peak at about 7-3 A ~ -'e on -*nt-.fim a l standard. The best internal standard HHS00000207 3 is calcium oxalate monohydrate (peak at 583 A). 4. The quantitative results are conditioned ty the fact that segregation effects in talc powders are considerable; the analytical method gives a reproducibility of 2 to 3$ average deviation in replicate determinations on the same sample, but different samples from the same bulk container are found to vary by as much as 200$. 5. The quantitative results are further complicated by the fact)i that antigorite gives an x-ray pattern that is indistinguishable from that of chrysotile. The HCl treatment specified above does not affect ground antigorite, but it is not yet known whether antigorite, if it occurs in talc, has the same chemical reactivity as the ground material from massive antigorite, or whether (like chrysotile) its properties may be variable depending upon the rock matrix in whicp it is found. 6. Subject to the qualifications inherent in the above, we have obtained quantitative estimates of the chrysotile contents of about 200 commercial talcum powder specimens. We have also determined the contents of the other minerals in these products, including tremolite, quartz, chlorite, dolomite, and others. There is no ambiguity in the identification of these latter species, but _the quantitative results for these are also affected by the segregation problem, which is most serious for those constituents present in the smallest amounts. 7. Most of the commercial talcs tested are free of any detectable amount mf any of the asbestiform minerals, according to the criteria enumerated above. Thus, there appears to be an adequate supply of talc for which there is no ambiguity about the absence of chrysotile or tremolite. In about 10$ of the samples tested, there appear to be definitely detectable amounts of either chrysotile or tremolite present.
