L. BOLAND C. 3. LIPSEN J. C. MOORS LAURENCE KIEFER ? The' meeting was opened by Chairman Foulger at 10:30 a.m President Battley,remarked that a list of raw materials that may be considered harm ful for use in5making paints for. application to children's toys and furniture and interior surfaces is extremely important to the paint manufacturer. . He referred to the contemplated action of the New York City and Chicago public health authorities requiring special precautionary labels for paints containing certain harmful metals. The Association has recommended precautionary labels for paints containing certain harmful ingredients, (copy attached). 'The Model Labeling Subcommittee recommended the .Association prepare a list of paint raw materials that might be harmful and dis tribute this information to members. In preparing this list, G-eneral Battley be lieves it is best to start with pigments. He expressed appreciation for the aid of the pigment manufacturers in this task.. . Mr. Boland gave a brief resume of a contemplated action by the New York City Board of Health and mentioned that originally the word "poison" was proposed for the label of paints containing lead. The draft of the proposed regulation is the result of cooperation between the New York City Health Department officials and representatives of the New York and National Paint, Varnish, -ana Lacquer Association. The Committee was asked for any suggestions for improvements in the draft of the regulation. Some suggestions were made and transmitted to the New York Cits'Health officials. The draft to be proposed at the New York Board of Health hearing on October 29 is attached Chairman Poulger called attention to the copy of a list of harmless and harmful pig ments used in different colored paints which was developed by the Children's Bureau, U.S. Department of Labor in. 19^2. This was checked by the National Bureau of Standards and the. National Institute of Health. This is not a list. of pigments pre pared by our Association, but is: based on such, a list prepared by the Association in 1939* Since that time additional information has been developed and new pigments have been produced. The information can, however, be used in the preparation of an up-to-date list of possible harmful paint ingredients. It is the-consensus of the = committee that there should be prepared (1) a list of pigments that would be con sidered unsuitable and later (2) a list of pigments that are known to be suitable. ^11699  However, it is quite evident that there is insufficient information on the possible toxicity of some pigments that places them, at the present time, in a doubtful class. After much discussion, it was agreed that the head: of this list shall: be as'follows:. MALERIALS SHOULD GAEHT: ; Basic Lead Carbonate Basic Lead Sulfate Basic Lead Silicates Leaded Zinc Oxides Antimony Oxide : Of Doubtful Classification Bed Pigments- Litharge or red lead Mercuric Oxide. V.Vermillion (mercuric sulfide) Cadmium red Lithol red Para, red Orange pigments Chrome.orange (basic lead chromate) Cadmium orange Molybdate orange (lead'chromate) Orange mineral (lead oxide) Yellow pigments Chrome yellow (lead chromate) 'Cadmium yellow Zinc yellow Green Pigments Chrome green (lead chromate.'yellow and iron blue) Paris Green 1 Blue Pigments Cadmium yellow Zinc yellow Copper phthalocyanine blue Dr. Foulger mentioned that he had tested:the toxicity of a grade of copper phthalo;cyaninO blue pigment and, found it .not harmful*. ..-However, alL: types of this pigment are not made/hy "the "same'processes and it was decided, to leave this pigment- in the ''doubtful'(-column* . Mr.. :polf remarked ;that there is already a commercial standard (CS 130-46) for. color materials' for .art materials used in schools, prepared in 19L6,: which gives the maximum allowable amount of possible toxic materials that can be included in "Color Materials for; Art Education". Reference to this.-particular publication -3- giy e s th e , foil owing words ' under, " To'xi c i ty" : "Shall not contain lead, arsenic or any other toxic materials in: excess of .05/3*" Hr. Rose mentioned the necessity for some accurate method of determining the per centage of lead to he allowed in paint. A standard is of little value unless the method; hi ^determining" the percent of lead or other Ingredientis; likewise a part-: of pur redommendation. Mr. Moore''recbmmehded"the testing method attached to this report. This is 'the lead chromate method and is the best to use when testing for medium: to' small quantities of lead. Certain pigments are placed in the questionable column because there is insufficier proof as to their toxicity. To be on the safe side they should not be used for making paints which are for application to children's toys and furniture or to interior.surfaces which might .be chewed by children. Mr. Todd remarked, it is very difficult for a small pigment manufacturer to deter mine the pigments that may be considered toxic.' She cost involved in determining. the proper toxicity,is excessive and the small manufacturer must depend upon the : Association for help. Dr. Foulger suggested that some,central laboratory might do this work for the industry as a whole. President Battley stated that we are working very closely with the Manufacturing Chemists Association. He further stated that we are not set up in our own labora tory to do toxicological work, but that it is essential this information be develop ed. The' adverse publicity we are. receiving in newspapers that paint is harmful , might result in reduced paint sales if something is not done about it. . He points out that we investigate thoroughly each sor-called child lead poisoning case. . Mr. Todd stated in reference to the possible toxicity of para red that there is a recent report, he believes from the Kettering Laboratories in Cincinnati, July 1954. He will endeavor to get a copy and send it to us for phosfcatating and transmittal to the committee members. Mr. Ksrpeles suggested that the Association secure information from the Pure Pood and Drug.Administration concerning the work,they have done on the toxicity of pig ments and other paint products. This will be done and a brief report will be sent to the committee members. Mr. Todd stated that some research work is being done on the use of radioactive isotopes in tracing the reaction of the possible toxicity of some chemicals. He will endeavor to get this information for transmittal: to the;committee. The Committee adjourned.at,4:30 p.m, Respectfully submitted. EFl ' 000842 PREGAUTIOiiRY LABELS EfiCOMfELDLD BTfHE.

Regardless of flash point, these clear liquids should bear appropriate Group I label plus warning "Do not take internally", because clear liquids may be attractive nuisances or mistaken for beverages. (b) Flash point determinations, in all cases,. refer to Tag. Open Cup Method, as specified in ASTM Method D 13llj.-5>ii.T. (c) Products classified in Group I which contain "odorless" solvents must be labeled with the appropriate Group I labels, but the warning words "Use with adequate ventilation" must be in type two points larger than the type used for the rest of the appropriate caution label and the label placed in a prominent position on the container. (d) The| percent of lead is determined as lead metal (Pb) based on the total solids of the paint.

First, determine the total nonvolatile material in a well-mixed sample of paint hy heating 3-5 grams in a flat-hottomed metal dish for one hour at 100-110C in an oven and determining the weight of residue.

Carefhlly burn off all organic material and complete the ashing with 1 si EHO-j until all carbon is removed and all acid-soluble material is in solution. Transfer the crucible and dried contents to a 400 ml. beaher and boil for about 2 minutes with an excess of acid ammonium acetate solution consisting of 95 ce. concentrated (sp.gr. 0.90) ammonium hydroxide and 125 ce. glacial acetic acid in 130 cc. water. If any insoluble matter is present, decant through a filter paper, leaving the residue in the beaker. . Treat the residue'with- additional acid ammonium acetate solution in the same manner.

Heat to boiling and add a moderate excess of 10$ solution of Eg^^O?. Heat until the yellow precipitate that first forms assumes an orange color. Allow to settle and filter by decantation onto a weighed Gooch or sintered glass crucible. Wash by decantation until the washings are colorless before transferring all of the precipitate.
