Skin-care cosmetics comprising bilayer systems and organic acid salts. Lautenschlaeger, Hans (Germany ). Ger. Offen. DE 4021082 A1 23 Jan 1992,11 pp. (Germany). CODEN: GWXXBX. CLASS: ICM: A61K009-127. ICS: A61K007-48; A61K031-685. APPLICATION: DE 90-4021082 3 Jul 1990. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Skin-care cosmetics, with high lipid content, comprise a liposomal bilayer source (phospho- or sphingolipids), salts of org. acids, lipids, alcs.There are some reagents with their cas registry numbers 866-83-1 and 593-29-3 are used in this study., and stabilizers. The salts of org. acids, which act as anionic emulsifiers, may be obtained in situ, by mixing the org. acid-contg. lipid phase into an alkali metal hydroxide-contg. aq. phase. A skin-care cream was prepd. by blending a lipid phase comprising phosphatidylcholine 6.0, avocado oil 15.0, vitamin E acetate 0.02, EtOH 14.0, and K stearate 1.2% by wt., into an aq. phase contg. urea 1.0, panthenol 1.0, mono-K fumarate 0.2 and H2O 61.4% by wt. .

Lisboa, Lisbon 1294, Port.). Port. Electrochim. Acta, 9(March), 105-12 (English) 1991.Several substances with their cas registry numbers 12408-02-5 and 866-83-1 may be metioned in this study. CODEN: PEACEZ. DOCUMENT TYPE: Journal CA Section: 79 (Inorganic Analytical Chemistry) Section cross-reference(s): 68 The variation of calcd. pH values of 0.01 M H3Cit solns. with added KCl and 0.1M K2Cit solns. with added KCl with exptl. values from the literature are discussed. While calcd. values always produce a line of neg. slope, exptl. studies of the citrate buffer from various supplies produced slopes that ranged from pos. to neg. Contamination is indicated. .
