Abstract:
A cleaning composition comprising:a) from 0.01% to 20% by weight, of a peroxygen bleach;b) from 0.001% to 30% by weight, of an ethoxylated nonionic surfactant having the formula:RO(CH.sub.2 CH.sub.2 O).sub.n Hwherein R is C.sub.6 -C.sub.22 alkyl, C.sub.6 -C.sub.28 alkylbenzene, and mixtures thereof, n is from 1 to 15;c) from 0.001% to 20% by weight, of a zwitterionic betaine surfactant having the formula:R.sub.1 N.sup.+ (R.sub.2)(R.sub.3)R.sub.4 X.sup.-wherein R.sub.1 is C.sub.1 -C.sub.24 alkyl; R.sub.2 is hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 hydroxyalkyl, C.sub.1 -C.sub.6 substituted alkyl, an amido unit having the formula:R.sub.a --C(O)--NH--(C(R.sub.b).sub.2).sub.mwherein R.sub.a is a saturated or unsaturated aliphatic unit which is substituted or unsubstituted, an aromatic unit which is substituted or unsubstituted, R.sub.b is hydrogen, hydroxy, and mixtures thereof, m is from 1 to 4; R.sub.3 is hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 hydroxyalkyl, C.sub.1 -C.sub.6 substituted alkyl, a sulfonate comprising C.sub.1 -C.sub.6 alkyl unit, a carboxylate comprising C.sub.1 -C.sub.6 alkyl unit, and mixtures thereof; R.sub.2 and R.sub.3 can be taken together with the nitrogen atom to form a C.sub.2 -C.sub.12 heterocyclic ring; R.sub.4 is C.sub.1 -C.sub.10 alkylene, C.sub.1 -C.sub.10 hydroxyalkylene, C.sub.1 -C.sub.10 polyalkyleneoxy, and mixtures thereof; X is a carboxylate or sulfonate unit; andd) the balance carriers and adjunct ingredients;wherein the ratio of nonionic surfactant to betaine surfactant is from 0.01 to 20, said composition having a pH up to 7.
