Kokai JP 52021317 17 Feb 1977 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A23L003-34. APPLICATION: JP 75-96956 9 Aug 1975. DOCUMENT TYPE: Patent CA Section: 17 (Foods) Monolaurates of glycerol, propylene glycol, and sorbitan, together with org. acids, such as fumaric acid [110-17-8], are used as preservatives for starch-contg. foods. For example, fumaric acid and propylene glycol monolaurate [10108-22-2] added to a kamaboko prepn. at 0.12 and 0.05%, resp., allowed the bacterial count to increase from 300 to 620/g kamaboko in 5 days, but the control without the preservatives had a count increase from 300 to 107/g in the same period. A glycerol monolaurate [27215-38-9] -fumaric acid mixt. was effective also.

Aqueous resin dispersions. Ishibe, Shuhei; Okumichi, Toshiharu; Ishihara, Yasushi; Naka, Hisayoshi (Arakawa Forest Chemical Industries, Ltd., Japan). Ger. Offen. DE 2647196 5 May 1977, 30 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08J003-06. PRIORITY: JP 75-127019 21 Oct 1975. DOCUMENT TYPE: Patent CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Na dodecyl sulfate (I) [151-21-3] or Na tetradecyl sulfate [1191-50-0] was used as the dispersant for the prepn. of stable aq. dispersions of resins used in the sizing of paper. Thus, 1800 parts tall oil resin was modified with 118 parts 37% aq. HCHO soln., mixed with 1200 parts balsam resin, mixed with 177 parts fumaric acid [110-17-8], and heated at 200.degree. for 3 h to prepare a resin which was mixed (100 parts) with 100 parts benzene and with 200 parts H2O contg. 1% I and distilled to remove benzene, giving a stable aq. dispersion.
