Preservative for coating compositions, which preservative comprises
a) one or more quaternary ammonium compounds and b) one or more alkalizing agents selected from amongst alkali metal hydroxide, alkali metal carbonate, alkali metal hydrogen carbonate, alkali metal silicate, alkaline earth metal oxide, alkaline earth metal hydrogen carbonate, alkaline earth metal hydroxide, alkaline earth metal silicate and Al(OH) 3 , and preserved coating composition.
摘要:
The invention relates to an isothiazolone-containing preservative which comprises the condensation product of a mixture comprising glycol, urea and formaldehyde. The invention further relates to the use of the preservative in technical products, to the technical product and to the use of the condensation product for stabilizing isothiazolones. The inventive preservative is free from 5-chloro-2-methylisothiazolone and 2-mercaptopyridine N-oxide and derivatives thereof and also has good storage stability in the form of the concentrate, even at elevated temperature.
摘要:
A liquid concentrate which comprises: a) from 20 to 70% by weight of 3-phenylpropan-1-ol, b) from 10 to 50% by weight of 1,2-octanediol, c) from 15 to 60% by weight of 1,3-propanediol, and d) where necessary up to 2000 ppm of one or more antioxidants; and a composition for topical application, comprising it.
摘要:
The invention relates to antimicrobial compositions which contain (i) at least one zinc compound selected from zinc salt and zinc oxide, (ii) at least one glycerine monoalkyl ether of the general formula
R-O-CH 2 -CHOH-CH 2 OH,
wherein R is a branched or unbranched C 1 -C 24 alkyl group, wherein the alkyl group can be substituted with one or more hydroxy and/or C 1 -C 4 alkoxy group(s) and/or the alkyl chain can be interrupted by up to four oxygen atoms, (iii) at least one antioxidant and optionally (iv) one or more alkanediols, wherein the weight ratio (w/w) of component (ii) to component (iii) is at least 10:1. The compositions are used in cosmetic and pharmaceutical products and already have broad antimicrobial activity, in particular against Pseudomonas aeruginosa, at active substance contents of only about 3 wt.%.
