Cosmetics containing natural coloring materials. (Pola Chemical Industries, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 59031705 A2 20 Feb 1984 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A61K007-00. APPLICATION: JP 82-140948 16 Aug 1982. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Natural coloring materials are adsorbed on porous MgO(OAlSiO3)2 or CaO(OAlSiO3)2 which are treated with a soln. of Al, Fe, Cu, Zn or Zr metal salts to form a prepn.There are some reagents with their cas registry numbers 1327-43-1 and 10043-67-1 are used in this study. for use in cosmetics. Thus, laccaic acid [60687-93-6] was adsorbed on CaO(OAlSiO3)2 which was treated with a soln. contg. 2.0% HOAc and 4.0% Al acetate to produce a coloring material. A face powder was prepd. contg. the coloring material 2.0, talc 85.7, kaolin 5.0, TiO2 2.0, iron oxide (yellow) 2.5, Ultramarine Blue 0.5, liq. paraffin 2.0 and perfumes 0.3%. .

Spectrophotometric studies on laccaic acid. Prasad, N.; Prasad, K. M.; Ghosh, A. K.; Khanna, B. B. (Indian Lac Res. Inst., Bihar, India). J. Oil Colour Chem. Assoc., 67(5), 117-18 (English) 1984. CODEN: JOCCAB. ISSN: 0030-1337. DOCUMENT TYPE: Journal CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 17 The absorption spectra of laccaic acid (I) [60687-93-6] in 4 different solvents were studied over the entire UV-visible range. A soln. of I in EtOH or MeOH exhibited lmax at 230, 292, 340, 500, and 530 m; in H2O at 292 and 490 m; and in acetone at 500 m.
