Abstract
Thickened aqueous compositions comprising soluble peracids, particularly peracetic acid, are provided. The compositions are thickened by the use of one or more aliphatic alcohol ethoxylates having the general formula: R.sup.1 R.sup.2 CH-- (OCH.sub.2 CH.sub.2).sub.n --OH in which R.sup.1 and R.sup.2 are each either hydrogen or linear or branched alkyl such that R.sup.1 plus R.sup.2 has a total of from 7 to 22 carbon atoms, and n is selected in the range of 1 to 15, such that the number ratio of carbon atoms in R.sup.1 plus R.sup.2 :n is greater than or equal to 3:1; a co-surfactant selected from the group consisting of anionic surfactants, amine oxides, amphoteric surfactants and quaternary ammonium compounds; and one or more aliphatic alcohol ethoxylates in which the ratio of the number of carbon atoms in the alcohol moiety to the average number of ethoxylate groups is less than 3:1, and/or alkylphenol ethoxylates.
