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:

• • • wherein R₁ and R₄ are independently selected from —H, linear, branched or cyclic alkyl or alkenyl having from 1 to 10 carbon atoms; and R₂ is a linear, branched or cyclic alkyl or alkenyl having from 3 to 10 carbon atoms, R₃ is a linear or branched alkyl from 3 to 6 carbon atoms, R₅ is H, methyl or ethyl and n=0-3.

Claims

1. A hard surface cleaning composition comprising:

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

1 to about 1;

2; and

from about 0.1% to about 10% by weight of the composition of a cleaning amine of formula;

a.

2. A composition according to claim 1 wherein R₁ and R₂ are both a higher alkyl independently selected from an alkyl comprising from about 4 to about 10 carbon atoms.

3. A composition according to claim 1 wherein R₁ and R₂ are a middle alkyl comprising about 3 carbon atoms.

4. A composition according to claim 1 wherein R₁ and R₂ are the same.

5. A composition according to claim 1 wherein R₁ is a lower alkyl and R₂ is a higher alkyl.

6. A composition according to claim 1 wherein R₁ and R₂ both have either about 3, about 4 or about 6 carbon atoms.

7. A composition according to claim 1 wherein the anionic surfactant is selected from the group consisting of alkyl sulfate, alkyl alkoxy sulfate, alkyl benzene sulfonate, paraffin sulfonate and mixtures thereof.

8. A composition according to claim 1 wherein the anionic surfactant is a mixture of alkyl sulfate and alkyl alkoxy sulfate and wherein the alkyl alkoxy sulfate is an alkyl ethoxy sulfate.

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

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

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

12. A method according to claim 11, wherein greasy soils are removed from said dishware.

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