Abstract
Abstract The degree of skin irritation of detergent compositions is reduced by adding small amounts of compounds having at least two polar groups, e.g. hydroxyl, carboxyl, ester, amino, and amido groups separated by an organic radical of at least 15 carbon atoms which contains a cyclic group. In particular, various aliphatic, aromatic and heterocyclic amino, amido and ester derivatives of polymerized fatty acids are disclosed.
