The present invention relates to liquid compositions comprising a peroxygen bleach, a liquid hydrophobic bleach activator and a polyhydroxy fatty acid amide surfactant according to the formula R 2 -C(O)-N(R 1 )-Z n wherein R 1 is H, or C 1- C 4 alkyl, C 1- C 4 hydrocarbyl, 2-hydroxy ethyl, 2-hydroxy propyl or a mixture thereof, R 2 is C 5- C 31 hydrocarbyl, and Z is a polyhydroxyhydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls directly connected to the chain, or an alkoxylated derivative thereof said compositions being formulated either as an emulsion or a microemulsion. The present invention further encompasses a process for pretreating soiled fabrics with a liquid composition comprising such a polyhydroxy fatty acid amide surfactant, whereby improved stain removal performance is delivered. |
