Hair care compositions comprising a 2-pyridinol-n-oxide material and an iron chelator
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.
1. A shampoo composition comprising:
a) from about 10% to about 20% of a detersive surfactant

c) from about 0.3% to about 6% of Diethylenetriaminepentakis (methylenephosphonic acid) wherein the combination of 1-hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)-2-pyridone monoethanolamine salt and Diethylenetriaminepentakis (methylenephosphonic acid) has a modified fractional inhibitor concentration of 50 ppm
d) from about 40% to about 95% of aqueous carrier.
2. The hair care composition of claim 1 wherein the 1-hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)-2-pyridone monoethanolamine salt material is from about 0.5% to about 2%.
