Abstract
A detergent composition mainly for automatic laundering machines which comprises, on the basis of 100 parts by weight of total composition, at least 60 parts of soap and no more than 10 parts of a mixture of surfactants comprising 10 to 30% of at least one non-ionic polyoxyalkylated surfactant and 90 to 70% of an anionic surfactant selected essentially from .alpha.-sulfonated fatty acids derivatives, the remainder of the composition comprising at least one ingredient selected from alkaline detergent additives, bleaching agents, optical brighteners, fragrances, antiredeposition agents and enzymes. The non-ionic surfactants are preferably fatty acid amides derived from tallow, copra or palm-oil condensed with polyoxyethylene residues. The anionic surfactants are preferably .alpha.-sulfonated fatty esters or amides derived from tallow, copra or palm-oil. The proper combination of said non-ionic and anionic surfactants with soaps impart to the laundering compositions an excellent detergent ability and foam control even in very soft waters and non-polluting properties.
