Abstract

A hard surface cleaning composition comprising:

• • a) from 1% to 60% by weight of the composition of a surfactant system; and
  • b) from 0.1% to 10% by weight of the composition of a cleaning amine of Formula (I):

• • • wherein the radicals R₁, R₂, R₃, R₄ and R₅ are independently selected from NH2, —H, linear or branched alkyl or alkenyl having from 1 to 10 carbon atoms and n is from 0 to 3 and wherein at least one of the radicals is NH2.

Claims

1. A hard surface cleaning composition comprising:

a) from about 1% to about 60% by weight of the composition of a surfactant system, wherein said surfactant system comprises an alkyl ethoxy sulfate and amphoteric/zwitterionic system wherein the amphoteric surfactant to zwitterionic surfactant weight ratio is from about 2;

1 to about 1;

2; and

wherein said amphoteric surfactant comprises an alkyl dimethyl amine oxide;

b) from about 0.1% to about 10% by weight of the composition of a cleaning amine of Formula(I);

2. A composition according to claim 1 further comprising an anionic surfactant selected from the group consisting of alkyl sulfate, alkyl benzene sulfonate, paraffin sulfonate and mixtures thereof.

3. A composition according to claim 1 further comprising an alkyl sulfate.

4. A composition according to claim 1 wherein the composition further comprises a non-ionic surfactant.

5. A composition according to claim 1 wherein the composition further comprises an aminocarboxylate chelant.

6. A method of manually washing dishware comprising the step of applying a composition according to claim 1 directly onto the dishware or onto a cleaning implement and using the cleaning implement to clean the dishware.

7. A method according to claim 6, wherein greasy soils are removed from said dishware.

9. A composition according to claim 1 wherein the composition further comprises a magnesium salt.

8. A hard surface cleaning composition comprising:

a) from about 1% to about 60% by weight of the composition of a surfactant system, wherein said surfactant system comprises an alkyl ethoxylated sulfate surfactant, an alkyl ethoxylated nonionic surfactant and an amphoteric/zwitterionic system wherein the amphoteric surfactant to zwitterionic surfactant weight ratio is from about 2;

1 to about 1;

2; and

wherein said amphoteric surfactant comprises an alkyl dimethyl amine oxide;

b) from about 0.1% to about 10% by weight of the composition of a cleaning amine of Formula(I);
