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.
Description
- The present invention is directed to hair care compositions comprising a 2-pyridinol-N-oxide material and an effective amount of an iron chelator.
- 1-Hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)-2-pyridone monoethanolamine salt, a 2-pyridinol-N-oxide material, is an anti-dandruff active used in shampoos, conditioners, and other treatments. Surprisingly, iron salt impurities can reduce the efficacy of 2-pyridinol-N-oxide materials. Therefore, there is a need to develop products that mitigate this phenomenon and provide higher efficacy. In the present invention it has been found that select iron chelators and 2-pyridinol-N-oxide materials provide significantly higher levels of anti-fungal activity than 2-pyridinol-N-oxide alone. More importantly and surprisingly and since some iron chelators show anti-fungal activity per se, said combinations of 2-pyridinol-N-oxide and certain iron chelators show anti-fungal activity significantly higher than the sum of anti-fungal activities of the components themselves. By utilizing 2-pyridinol-N-oxide materials in combination with select iron chelators, the present invention delivers compositions and products with superior anti-dandruff performance.
- The present invention is directed to a hair care composition comprising an effective amount of a 2-pyridinol-N-oxide material, 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.

- I. Method overview:
-
- 1. Each MFIC assay is run in duplicate.
- 2. Low levels of M. Furfur 7892 cells are inoculated into each well of a 96 well plate.
- 3. Chemical #1 (in our assays this is always a 2-pyridinol-N-oxide material) is added at a concentration equal to ½ the concentration of its MIC concentration.
- 4. Chemical #2 is titrated (2× concentration reduction) across each well in the same row, starting at 400 ppm.
- 5. Plates are incubated at 33° C. for 2 days.
- 6. Optical densities (OD's) are then determined using a spectrophotometer.
- II. Data Analysis
-
- 1. Inhibition of growth is determined if the culture optical density is less than or equal to ⅕ (20%) of the culture optical density of the untreated control
- 2. The MFIC is determined as the average value of the lowest concentration value of Material #2 that inhibits growth.

The MFIC value of 1-hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)-2-pyridone monoethanolamine salt in combination with EDTA is greater than 100 ppm, indicating this combination has a low level of efficacy.
- The strength of the association between a ligand and metal, in this case iron, can be termed iron affinity. A high iron binding affinity is required for chelators to effectively compete with iron salt impurities that reduce the efficacy of 2-pyridinol-N-oxide materials.
- Affinity between a metal (M) and ligand (L) can be measured by the stepwise association constant, K1 which describes the following equilibrium:
-
- The affinity constant is conveniently expressed as the logarithm (log K1) and the larger the magnitude of this number, the stronger the association between the metal (iron ions in this case) and ligand.

The formation of a shampoo gel network involves heating a dispersion of the fatty alcohol in water with the surfactant to a temperature above the melting point of the fatty alcohol. During the mixing process, the fatty alcohol melts, allowing the surfactant to partition into the fatty alcohol droplets. The surfactant brings water along with it into the fatty alcohol. This changes the isotropic fatty alcohol drops into liquid crystalline phase drops. When the mixture is cooled below the chain melt temperature, the liquid crystal phase is converted into a solid crystalline gel network.
