Aqueous liquid washing composition

Aqueous liquid washing composition. Tai, Ho Tan (Unilever N. V., Neth.). Ger. Offen. DE 2710727 22 Sep 1977, 14 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C11D001-37. PRIORITY: GB 76-9802 11 Mar 1976. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Mixts. of octanephosphonic acid (I) [4724-48-5] and Na xylenesulfonate (II) [1300-72-7] or Na toluenesulfonate [12068-03-0] were used as hydrotrope systems in the prepn. of stable liq. washing compns. Thus, a stable liq. detergent contained dodecylbenzenesulfonic acid 6.5, dimerized oleic acid 5, epoxylated fatty alcs. 2.7, poly(acrylic acid) (mol. wt. 3500-5000) 2, CM-cellulose 0.5, Na silicate 11, KOH 3, K2CO3 7, I 1, 40.7% II 10, and water 51.65%. Without the I, 18-20% II (40.7% active material) was required to give stable solns.

Softener dispersion

Softener dispersion. Wixon, Harold E. (Colgate-Palmolive Co., USA). U.S. US 3997453 14 Dec 1976, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: D06M013-32. NCL: 252008750. APPLICATION: US 72-250427 4 May 1972.In this article, certain chemicals are used. Some of their cas registry numbers are 26248-24-8 and 13470-50-3 DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Na xylenesulfonate (I) [1300-72-7], Na n-tridecylbenzenesulfonate [26248-24-8], or a similar sulfonate was used in solns. of a quaternary ammonium compd. (textile softener) to improve the dispersibility of the soln. in cold water. Thus, 100 g liq. softener contg. 2-heptadecyl-1-methyl-1-[2-(stearamido)ethyl]imidazolinium Me sulfate [13470-50-3] 7.1, Calcofluor CSL brightener 0.28, and 1% Acid Blue 80 soln. 1.5% was mixed with 0.4% I to reduce the viscosity of the softener soln. and improve the dispersibility in cold water. .
