Pearly agents for cosmetics

Pearly agents for cosmetics. (Kao Corp., Japan). Jpn. Kokai Tokkyo Koho JP 59232197 A2 26 Dec 1984 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C11D003-40. APPLICATION: JP 83-107241 15 Jun 1983. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 46 Pearly agents for cosmetics consist of 0.05-50% hydrophilic surfactants and 1-50% glycerol fatty acid esters [contg. >80% of the glycerol mono fatty acid esters RCO2CH2CH(OH)CH2OH (where R = C11-23 straight or branched-chain, satd. or unsatd. hydrocarbon group)]. Thus, a pearly agent contained Na polyoxyethylene lauryl sulfate [9004-82-4] 5, Atmul T95 (contg. 87% monostearoyl glyceride [123-94-4]) 5, EtOH 2, and H2O 88%. The prepn. was stable and homogeneous.

DOCUMENT TYPE: Journal CA Section: 76 (Electric Phenomena) Section cross-reference(s): 36 Space charge is formed in cables insulated with crosslinked polyethylene. The crosslinking byproduct or the crosslinked polymer morphol. is responsible for the space charge. In order to examine the former possibility, an additive-free low-d. polyethylene sheet was soaked in various liq. chems. including the crosslinking byproducts and space charge distribution inside the sheet was measured under do voltage application. As a result, space charge appears in the vicinity of the injecting electrode only in the case that the sheet was soaked in the liqs. with at least one hydroxyl group in their structures. Therefore, cumyl alc., which is the only byproduct with a hydroxyl group in its structure, is responsible for the formation of space charge in polyethylene on the assumptions that chem. functions of a given mol. act sep. from each other and that other contributions such as the crosslinked polymer morphol. 98-83-9 and 123-94-4 are just another two chemicals used in this study. are negligible. .
