Abstract
A hair conditioner composition containing an aqueous carrier, a cationic surfactant, a high melting point fatty compound and an effective preservation system. The conditioner composition comprises a gel network. The preservation system contains sodium benzoate and a second composition selected from the group consisting of glycol, glyceryl ester, and combinations thereof.
Claims13
A hair conditioner composition comprising:
- a) about 50% to about 95% of an aqueous carrier, by weight of the composition;
- b) about 0.1% to about 10% of a cationic surfactant, by weight of the composition;
- c) about 1.5% to about 15% of a high melting point fatty compound, by weight of the composition;
- d) a preservation system comprising:
- i) 0.2% to 0.4% sodium benzoate, by weight of the composition;
- ii) about 0.4% by weight of the composition, of a second composition selected from the group consisting of glycol, glyceryl ester, and combinations thereof;
- wherein the weight ratio of sodium benzoate to the second composition is about 1:2 to about 1:1;
- and
- e) a gel network,
- wherein the conditioner composition has a pH off about 2.5 to about 5, is free of anionic surfactant, and has an undetectable microbe level at two days according to the Bacterial and Fungal Microbial Susceptibility Test.

A hair conditioner composition that is a solid crystalline gel network comprising:
- a) about 50% to about 95% of an aqueous carrier, by weight of the composition;
- b) about 0.1 wt % to about 10 wt %, by weight of the composition, of a single cationic surfactant selected from the group consisting of behenamidopropyl dimethylamine, behentrimonium chloride, cetrimonium chloride, stearamidopropyl dimethylamine, and combinations thereof, wherein the composition is free of other surfactants;
