Abstract
The present invention relates to perfumed compositions comprising polymer and nonionic surfactant and is explained with particular reference to insect-repellent compositions which are a preferred embodiment of the invention. The invention provides an aqueous cleaning composition comprising: a nonionic surfactant, a carboxylate polymer, and, a perfume. Preferably the compositions of the invention are aqueous cleaning composition of pH 3.5-5.5 comprising: PA1 a) 1-10% wt of an ethoxylated alcohol, PA1 b) 0.1-4% wt of a carboxylate polymer, PA1 c) 0.2-4% wt of a perfume component selected from the group comprising limonene, carvone, cineole, linalool, Gum Camphor, citronellal, alpha and beta terpenol, fencholic acid, borneol, iso borneol, bornyl acetate, iso bornyl acetate and mixtures thereof, and, PA1 d) 82-99% water, wherein the weight ratio of (a):(c) does not exceed 10:1.
