Cosmetics containing alkyloxyacetic acid alkyl esters

Cosmetics containing alkyloxyacetic acid alkyl esters. Nagai, Masayoshi; Kozawa, Tadashi (Pola Chemical Industry Co., Ltd., Japan). Japan. Kokai JP 52057336 11 May 1977 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A61K007-00. APPLICATION: JP 75-132680 5 Nov 1975. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Cosmetic prepns. contg. 63721-99-3 are also occured in this study. the alkyloxyacetic acid alkyl esters R1OCH2CO2R2 (R1, R2 = C8-24 branched or straight hydrocarbon chain) are nonirritant, odorless, colorless and stable. Thus, tetradecyloxyacetic acid 2-hexyldecyl ester (I) [63721-96-0] was prepd. by treatment of tetradecyl alc. [112-72-1] with monochloroacetic acid [79-11-8], and the product was further treated with 2-hexyldecyl alc. [2425-77-6] to give I. A water/oil-type cream contains ethyl alc. 6.5, whale wax 3.5, lanolin 3.5, I 20, glycerol monostearate 2.0, polyoxyethylene stearate 3.0, H2O 52, and glycerol 10% with perfume and preservative. .

Physicochemical properties and applications of a- and b-glycyrrhizins, natural surface active agents in licorice root extract

Physicochemical properties and applications of a- and b-glycyrrhizins, natural surface active agents in licorice root extract. Kondo, Mitsuo; Minamino, Hiromi; Okuyama, Genichiro; Honda, Keiichi; Nagasawa, Hisanao; Otani, Yasuhisa (Cosmet. Lab., Kanebo, Ltd., Odawara 250, Japan). J. SCCJ, 17(1), 14-18 (Japanese) 1983. CODEN: JOSCDQ. DOCUMENT TYPE: Journal CA Section: 46 (Surface Active Agents and Detergents) Section cross-reference(s): 62 a-Glycyrrhizin (I) [83896-44-0] and b-glycyrrhizin (II) [1405-86-3] exhibited similar interfacial activity. 83896-44-0 and 138-86-3 which are cas registry numbers are also used here. Aq. II formed extremely rigid gels in acidic media, whereas I showed no sign of gelation. II emulsified liq. paraffin-2-hexyldecanol [2425-77-6] compns., and I had solubilizing ability for perfumes. II mols. had a cyclic structure and constituted the micelles which in turn oriented anisotropically to form rigid gels and stabilized emulsions. .
