Detergent composition |
(57) A detergent composition for washing fabrics contains a surfactant system in which
the major anionic surfactant is an alkyl sulphate of mixed alkyl chain length such
that at least 10% by weight of the alkyl chains present in the alkyl sulphate are
C₁₂ chains, at least 20% by weight of said alkyl chains are C₁₈ chains and the ratio
of C₁₂ alkyl chains to C₁₈ alkyl chains is in the range 9:4 to 1:6.
Preferably nonionic surfactant of low HLB value (i.e. less than 10.5) is also present.
