Studies on food additives. Effects of phosphate condensates on the preservative activity of the food preservatives. Moon, Beum Soo (Natl. Inst. Health, Seoul, S. Korea). Yakhak Hoe Chi, 21(1), 1-16 (Korean) 1977. CODEN: YAHOA3. DOCUMENT TYPE: Journal CA Section: 17 (Foods) Condensed phosphates generally increased the efficacy of food preservatives with respect to microorganism inhibition. Na2H2P2O7 [7758-16-9] was best; anhyd. Na4P2O7 [7722-88-5], Na polyphosphate, Na tripolyphosphate, and Na hexametaphosphate [10124-56-8] under certain conditions were ineffective, and may have been deleterious. (NaPO3)6 [10361-03-2] had a variable effect; perhaps the effective compd. was an impurity. Preservatives tested were benzoic acid [65-85-0], Na dehydroascorbate [51260-76-5], K sorbate [24634-61-5], NaNO2 [7632-00-0], Bu p-hydroxybenzoate [94-26-8], and AF2 [2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide] [3688-53-7].

Agent for finishing fiber materials

Agent for finishing fiber materials. Klein, Albert (Hoechst A.-G., Ger.). Ger.Chemicals with cas numbers 9043-30-5 and 62132-75-6 also play role. Offen. DE 2528258 13 Jan 1977, 22 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: D06M015-32. APPLICATION: DE 75-2528258 25 Jun 1975. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Compns. for the antistatic and soil-release finishing of textiles contain fluoroalkyl group-contg. polymer, anionic or nonionic emulsifier (for the fluoropolymer), phosphoric acid ester with the formula (RO)bP(O)(OM)3-b (R = C6-20 alkyl; M = alkali metal ion; b = 1 or 2) and(or) a polyoxyalkylene with the formula R1O(CnH2nO)mY (R = C6-18 alkyl, n = 2 or 3; m = 2-30; Y = H or SO3M), and(or) a polymer consisting of styrene [100-42-5] 60-90, alkyl (meth)acrylate 4-20, and (meth)acrylic acid and(or) (meth)acrylamide 0-20 parts, and an acid donor catalyst for the fluoropolymer. Thus, 400 mL compn. contg. 4.5 g mixt. consisting of fluoropolymer emulsion 35, potassium dilauryl phosphate [19045-76-2] 35, and disodium pyrophosphate [7758-16-9] 25 parts was applied to the back of a 1 m2 sample of tufted nylon carpeting and dried at 150.degree.. The carpet had good antistatic and soil-release properties. .
