Abstract
Liquid detergent compositions, are disclosed, comprising a surfactant and a builder mainly comprised of a quaternary ammonium salt of a carboxyl-containing polymer, which has good compatibility with surfactants and is capable of providing excellent detergency, especially, against mud dirt in washing clothes.Detergent compositions, are also disclosed, containing an alkoxylated alcohol nonionic surfactant having a specific distribution constant and narrow molecular weight distribution or an anionic surfactant derived therefrom, together with one or more of a quaternary ammonium or organic amine salt of a carboxyl group-containing polymer, a cationic surfactant and a quaternary ammonium or organic amine salt of a low molecular weight polycarboxylic acid, whereby detergency is synergistically enhanced.
