Claims13
A cleaning or bleaching composition comprising water, from 1 to 20 percent by weight of an alkali metal hypochlorite, measured as available chlorine, and from 0.1 to 5 percent by weight of an amine oxide component comprising a branched amine oxide which contains a ##STR9## group, where R is a straight chain C.sub.5 to C.sub.17 alkyl group, R.sup.1 is a C.sub.1 to C.sub.3 alkyl group and the group ##STR10## contains 8 to 20 carbon atoms, the amine oxide in toto having the formula:
- ##STR11## where R.sup.2 and R.sup.3, which may be the same or different, are each alkyl groups containing up to six carbon atoms.
A cleaning or bleaching composition comprising:
- (1) from 1 to 20 percent by weight of the composition of an alkali metal hypochlorite, measured as available chlorine,
- (2) from 0.1 to 5 percent by weight of a mixture of 40 to 60 weight percent straight chain amine oxide and 60 to 40 weight percent branched chain amine oxide, the amine oxide containing a ##STR13## group, where R is a straight chain C.sub.5 to C.sub.17 alkyl group and
- R.sup.1 is a C.sub.1 to C.sub.3 alkyl group, and the group ##STR14## contains 8 to 20 carbon atoms, the amine oxide in toto having the formula:
- ##STR15## where R.sup.2 and R.sup.3, which may be the same or different, are each alkyl groups containing up to 6 carbon atoms, and (3) balance water.
