Abstract

The present invention is directed to a hair care composition having an effective amount of a 2-pyridinol-N-oxide material and an effective amount of an iron chelator; wherein the combination of the iron chelator and the 2-pyridinol-N-oxide material provides high anti-fungal efficacy.

First claim

What is claimed is:

1. A shampoo composition comprising:
a) about 10% to about 20% of a detersive surfactant
b) about 0.1% to about 10% of 1-hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)-2-pyridone monoethanolamine salt;
c) from about 0.3% to about 6% of diethylenetriaminepentaacetic acid wherein the combination of 1-hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)-2-pyridone monoethanolamine salt and diethylenetriaminepentaacetic acid has a modified fractional inhibitor concentration of less than about 50 ppm;
d) from about 40% to about 95% aqueous carrier.

2. The hair care composition of claim 1 , further comprising an iron chelator wherein the iron chelator is desferrioxamine.

3. The shampoo composition of claim 1 wherein the 1-hydroxy-4-methyl-6-(2,4,4- trimethylpentyl)-2-pyridone monoethanolamine salt is present at about 0.3% to about 3%.

4. The shampoo composition of claim 1 , further comprising a gel matrix, the gel matrix comprising :
a) about 0.1% to about 20% of fatty alcohol, wherein the fatty alcohol having from 16- 22 carbon atoms
b) about 0.1% to about 10% of a cationic surfactant
c) about 20% to about 95% of aqueous carrier.
