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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The hair conditioner composition of claim 1, wherein the second composition comprises a glycol selected from the group consisting of butylene glycol, pentylene glycol, hexylene glycol, 1,2-hexanediol, caprylyl glycol, decylene glycol, and mixtures thereof. ### Claim 3 (depends on 1) The hair conditioner composition of claim 1, wherein the glycol comprises caprylyl glycol. ### Claim 4 (depends on 1) The hair conditioner composition of claim 1, wherein the second composition comprises a glyceryl ester selected from the group consisting of glyceryl capiyiate, glyceryl caprate, glyceryl undecylenate and mixtures thereof. ### Claim 5 (depends on 1) The hair conditioner composition of claim 1, wherein the cationic surfactant is selected from the group consisting of behenamidopropyl dimethylamine, behentrimonium chloride, cetrimonium chloride, stearamidopropyl dimethylamine, and combinations thereof. ### Claim 6 (depends on 1) The hair conditioner composition of claim 1, wherein the high melting point fatty compound is a fatty alcohol selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, brassica alcohol, and combinations thereof. ### Claim 7 (depends on 1) The hair conditioner composition of claim 1, wherein the conditioner composition has a shear stress off about 50 Pa to about 500 Pa, as measured according to Shear Stress Test Method. ### Claim 8 (depends on 1) The hair conditioner composition of claim 1, wherein the preservation system is substantially free of a preservative ingredient selected from the group consisting of ethylenediaminetetraacetic acid and salts thereof, isothiazolinones, benzyl alcohol, phenoxyethanol, cyclohexylglycerin, parabens, and combinations thereof. ### Claim 9 (depends on 1) The hair conditioner composition of claim 1, wherein the composition is substantially free of an ingredient selected from the group consisting of silicone, propellants, phthalates, dyes, sulfates, formaldehyde donors, and combinations thereof. ### Claim 10 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; c) about 1.5 wt % to about 15 wt % of a fatty alcohol selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, and brassica alcohol; d) a preservation system comprising: i) about 0.2% to 0.4% sodium benzoate, by weight of the composition; ii) about 0.4% a glycol selected from the group consisting of butylene glycol, pentylene glycol, hexylene glycol, 1,2-hexanediol, caprylyl glycol, decylene glycol, and mixtures thereof; wherein the weight ratio of sodium benzoate to the glycol is about 1:2 to 1:1; and e) a gel network, wherein the composition has an undetectable microbe level at two days, according to the Bacterial and Fungal Microbial Susceptibility Test. ### Claim 11 (depends on 10) The hair care composition of claim 10, wherein the glycol comprises caprylyl glycol. ### Claim 12 (depends on 10) The hair care composition of claim 10, wherein the surfactant comprises behenamidopropyl dimethylamine. ### Claim 13 (depends on 10) The hair conditioner composition of claim 10, wherein microbes are undetectable at two days, as measured according to Bacterial and Fungal Microbial Susceptibility Test Methods.
