Abstract: Low-foaming disinfectant and cleaning compsns. contain ethers of formula: R-O-(X.O)-nC(CH3)3 (I), pref. at 0.5-20 wt.% (where R= 6-22C alk(en)yl; X= 2-3C alkylene; n=5-50). Active disinfectant component, pref. used at 0.5-10 wt. %, is either a quat. cpd. of formula R1R2R3R4+N Y- (R1 and R2 = (m)ethyl; R3 and R4= 8-18C alk(en)yl, or benzyl; Y- = halo or CH3OSO3-), or trichloroisocyanuric acid. (I) are effective foam suppressants for cationic and nonionic cpds.; are stable in alkaline soln. and in presence of caustic alkali, and have excellent surfactant props.

Abstract: 1484918 Detergent compositions HOECHST AG 15 Nov 1974 [16 Nov 1973] 49538/74 Heading C5D [Also in Division C2] Anionio cationic and/or non-ionic detergent compositions contain as an anti-microbial agent a compound of formula in which one or two of the radicals R 1 to R 7 represent a C 8-18 alkyl or alkenyl radical, one or two of the radicals R 2 -R 6 represent a radical of formula wherein Y is a hydrogen or alkali metal atom, each of the remaining radicals R 1 to R 7 represent a hydrogen atom or a methyl group, n is 2 or 3 and o and p are zero or 1. The compositions may also contain optical brightening agents, perborates, enzymes, perfumes, fluorescence agents, foam-producing and foam-depressing agents, and deposit-preventing auxiliaries. Examples disclose compositions containing antimicrobial compounds as above together with (3) the sodium salt of a secondary alkane sulphonic acid (or the sodium salt of dodecylbenzene sulphonic acid or a mixture of the former with the sodium salt of a C 15-18 olefin sulphonate), oxyethylated tallow fatty alcohol, sodium soap, sodium tripolyphosphate, sodium metasilicate, magnesium silicate, carboxymethyl cellulose, optical brightener, perfume oil and sodium perborate, (4) oxyethylated coco fatty acid, oxyethylated isotridecyl alcohol, sodium tripolyphosphate, sodium silicate, calcined sodium carbonate, carboxymethyl cellulose and sodium sulphate, (5) distearyl-dimethylammonium chloride, oxyethylated oleyl alcohol, an optical brightener and perfume oil, (6) oxyethylated coco fatty alcohol, perfume and dyestuffs, (7) oxyethylated coco fatty alcohol, sodium tripolyphosphate, sodium silicate, calcined sodium carbonate, carboxymethyl cellulose and sodium sulphate.

Abstract: Detergent for dish washing machines contains a nonionic polyglycol tert.-butyl ether (I) of the formula R-O(XO)n-Bu-t (in which R is a 6-22C alk(en)yl gp., pref. 8-14C alkyl gp., X is a 2-3C alkylene gp. n= 5-50, pref. 5-30), pref. in an amt. of 0.5-20 wt.%. (I) form very little foam in aq. soln. and can be used as foam suppressants for nonionic and cationic cpds. They are stable in alkaline soln., even in the presence of caustic alkali, and have excellent detergent and wetting properties. In an example an alkaline detergent consisted of 2.0 (wt.) pts. (I) (in which R is 10-12C alkyl, X is -CH2CH2- and n=10), 41.5 pts. Na2SiO3, 35.0 pts. Na5P3O10, 1.5 pts. Na dichloroisocyanurate and 20.0 pts. Na2CO3.

Abstract: Detergent for mejtals contains a nonionic polyglycol tert. - butyl ether (I) of formula R-O(XO)n-Bu-t (in which R is a 6-22C alk(en)yl gp., pref. 8-14C alkyl gp.; X is a 2-3C alkylene gp.; n=5-50, pref. 5-30), pref. in an amt. of 0.5 20 wt. %. (I) can be used in compsns. applied to metals by dipping or spraying opt. in conjunction with other nonionic, a cationic or anionic surfactants and other additives. Concns. of 1-10 wt. % are esp. suitable. (I) form very little foam in aq. soln. and can be used as foam suppressants for nonionic and cationic cpds. They are stable in alkaline soln., even in the presence of caustic alkali, and have excellent detergent and wetting properties.
