Stable bleaching agent mixture: Stable bleaching agent mixture. Yagi, Kouichi; Yamanaka, Makoto; Fujino, Takashi (Kao Soap Co., Ltd., Japan). Ger. Offen. DE 2622761 16 Dec 1976, 23 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C11D003-39. PRIORITY: JP 75-67268 4 Jun 1975. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Twenty five salicylamido compds. (RNHCOR1, where R is a substituted or unsubstituted triazolyl, tetrazolyl, imidazolyl, triazinyl, or pyrazolyl group attached through a C and R1 is a substituted or unsubstituted 2-hydroxyphenyl group) were used to stabilize Na percarbonate (I) [15630-89-4], Na perborate [7632-04-4], and Na peroxypyrophosphate [13769-85-2] bleaching agents against loss of active O during storage as mixts. with detergent powders. Thus, a mixt. of 10 parts I and 90 parts anionic detergent powder contg. 1% 3-salicylamido-1H-1,2,4-triazole (II) [36411-52-6] had 80% of the original active O content after 30 days at 30.In this experiment, several chemicals are used like 61745-82-2 and 38916-54-0 degree. and 80% relative humidity, compared with 25% without the II. .

Bleaching composition: Bleaching composition. Nakagawa, Yunosuke; Yagi, Kouichi; Inamori, Yoshihiro; Kawahara, Yoshiharu; Fujiwara, Hiroichi (Kao Soap Co., Ltd., Japan). Ger. Offen. DE 2636037 17 Mar 1977, 15 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: D06L003-02. PRIORITY: JP 75-107366 4 Sep 1975.Several substances with their cas registry numbers 64-19-7 and 597-71-7 may be metioned in this study. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Pentaerythritol tetraacetate (I) [597-71-7] is an effective activator for inorg. peroxide bleaching agents. Thus, a compn. contg. I 10 (prepd. by esterifying pentaerythritol [115-77-5] with HOAc [64-19-7]), Na perborate [7632-04-4] 30, Na tripolyphosphate 10, and Na2SO4 50 g was a more effective bleach for soiled cotton fabrics than a similar compn. contg. no I. .
