ABSTRACT:
The invention concerns detergent compositions comprising a special type of oxidation resistant nonionic surfactant and an oxidizing agent which may either be a hypochlorite or a peroxygen material. The surfactant component structurally comprises a C.sub.8 -C.sub.12 alkyl substituted phenoxy hydrophobe alkoxylated with ethylene oxide and/or propylene oxide, with the proviso that the ratio of ethylene oxide to propylene oxide is at least 1 but no higher than 10. Methyl or chloroethyl groups are used to endcap the surfactant.
