PERSONAL CARE COMPOSITIONS SUBSTANTIALLY FREE OF SULFATED SURFACTANTS AND CONTAINING A GEL NETWORK
A personal care composition substantially free of sulfated surfactants includes a dispersed gel network, a detersive surfactant, and water. The dispersed gel network includes one or more fatty alcohols, a gel network surfactant, and water. Methods of making a personal care composition are also disclosed.
1 . A personal care composition comprising:
a dispersed gel network comprising:
about 0.05% or more, by weight of the personal care composition, of one or more fatty alcohols,
about 0.01% or more, by weight of the personal care composition, of a gel network surfactant, the gel network surfactant selected from a first group consisting of anionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants, non-ionic surfactants, and mixtures thereof; and
water;
a detersive surfactant selected from a second group consisting of an anionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants, non-ionic surfactants, and mixtures thereof; and
liquid carrier; and
wherein the personal care composition is substantially free of sulfated surfactants.
2 . The personal care composition of claim 1 , wherein the gel network surfactant and the detersive surfactant each independently comprise an isethionate, a sarcosinate, a sulfonate, a sulfosuccinate, a sulfoacetate, a glycinate, a glutamate, an ester, a carboxylate, an amphoacetate, a taurate, an acylamino acid, a betaine, a sultaine, or a mixture thereof.
3 . A personal care composition of claim 1 , wherein the gel network surfactant comprises a phosphate ester.
4 . A personal care composition of claim 1 , wherein the gel network surfactant comprises one or more of cetrimonium chloride, stearimonium chloride, behentrimonium chloride, behentrimonium methosulfate, behenamidopropyltrimonium methosulfate, stearamidopropyltrimonium chloride, arachidtrimonium chloride, and distearyldimonium chloride.
5 . A personal care composition of claim 1 , wherein the gel network surfactant and the detersive surfactant are different.
6 . A personal care composition of claim 1 , comprising about 5% or more, by weight of the personal care composition, of the detersive surfactant.
7 . A personal care composition of claim 1 , wherein the dispersed gel network further comprises one or more fatty compounds selected from the group consisting of fatty amides, di-fatty ethers, fatty carbamates, fatty acids, fatty esters, fatty phosphorus compounds, fatty sorbitan derivatives, alkyl sulfoxides, and mixtures thereof.
8 . A personal care composition of claim 1 , further comprising a stabilizing agent comprising one or more of trihydroxystearin, ethylene glycol distearate, citric, citrate, a preservative, sodium chloride, sodium benzoate, ethylenediaminetetraacetic acid (“EDTA”) or a salt thereof.
9 . A personal care composition of claim 1 , wherein the one or more fatty alcohols comprise one or more of cetyl alcohol, stearyl alcohol, and behenyl alcohol.
10 . The personal care composition of claim 1 , comprising about 5% to about 30%, by weight, of the detersive surfactant and gel network surfactant.
11 . A personal care composition of claim 1 , further comprising a cationic polymer comprising one or more guar derivatives, synthetic derivatives, and cellulose derivatives.
12 . A personal care composition of claim 1 , further comprising a silicone conditioning agent comprising one or more of dimethicone, dimethiconol, and an amino silicone.
13 . A personal care composition of claim 1 , comprising about 1% to about 10%, by weight, of the one or more fatty alcohols and the gel network surfactant.
14 . The personal care composition of claim 1 , wherein the personal care composition is a shampoo.
15 . The personal care composition of claim 14 , wherein the shampoo removes more oil from hair than a similar personal care composition formed without the dispersed gel network.
16 . The personal care composition of claim 14 , wherein the shampoo produces a higher volume of lather than a similar personal care composition formed without the dispersed gel network.
17 . The personal care composition of claim 1 , wherein the personal care composition is substantially free of sulfates.
18 . A method of producing a personal care composition, the method comprising:
a) combining one or more fatty alcohols and a gel network surfactant in a water solution in a weight ratio of about 1:10 to a ratio of about 40:1 at a temperature sufficient to allow partitioning of the gel network surfactant into the one or more fatty alcohols to form a mixture;
b) cooling the mixture to a temperature below the chain melt temperature of the one or more fatty alcohols to form a gel network; and
c) adding the gel network to a detersive surfactant and a liquid carrier to form a personal care composition; and
wherein the personal care composition is substantially free of sulfated surfactants.
19 . The method of claim 18 , wherein the gel network surfactant and the detersive surfactant each independently comprise an isethionate, a sarcosinate, a sulfonate, a sulfosuccinate, a sulfoacetate, a glycinate, a glutamate, an ester, a carboxylate, an amphoacetate, a taurate, quaternium, behenyltrimethylammonium chloride, or a mixture thereof.
20 . A method of cleansing without sulfates, the method comprising:
providing a personal care composition substantially free of sulfated surfactants comprising:
a dispersed gel network comprising:
about 0.05% or more, by weight of the personal care composition, of one or more fatty alcohols;
about 0.01% or more, by weight of the personal care composition, of a gel network surfactant, the gel network surfactant selected from a first group consisting of anionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants, non-ionic surfactants, and mixtures thereof; and
water; and
a detersive surfactant selected from a second group consisting of an anionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants, non-ionic surfactants, and mixtures thereof; and
liquid carrier; and
forming a lather with water and the personal care composition to clean a substrate; and
rinsing the lather out of the substrate.
