STERICALLY HINDERED POLYETHER POLYOLS AS CHLORINE BLEACH STABLE SURFACTANTS Abstract of the Disclosure Cleaning compositions, especially liquid detergent compositions containing chlorine bleach, are disclosed. The compositions include a chlorine bleach stable nonionic surfactant which is a mixture of the formula Y[A1O)n(A2O)n'(A3O)n"H]m wherein Al and A2 are C2-C4 alkylene groups, tetramethylene and mixtures thereof, A3 is a sterically hindered C4-C30 alkylene group, C4-C30 arylalkylene group, and mixtures thereof, n + n' = a value such that the total molecular weight of the uncapped portion of the molecule is about 500 to 25,000, n" is a number from 1 to 8, m is a number from 1 to 8, and Y is the residue of an organic compound having from about 1 to 30 carbon atoms and at least 1 reactive hydrogen atom. The surfactant has a hydrophilic content of from about 5 to 40 weight percent. - 40 -
