Abstract:
Provided is a sulfate-free surfactant system which is particularly suitable for use in personal hygiene products. The sulfate-free surfactant system comprises a liquid comprising an organic phase and a solvent wherein the organic phase comprises glyceride and surfactant and the liquid comprises:
4-40 wt % glyceride wherein the glyceride is the condensation reaction product of at least 1.10 moles of a mixture of acids to no more than 2.1 moles of mixture of acids per mole of glycerin;
wherein mixture of acids comprises:
at least 0.275 to no more than 0.990 moles of a first acid comprising a branched acid with 16-20 aliphatic carbons;
at least 0.250 to no more than 0.810 moles of a second acid comprising an alkyl acid with 9-11 carbons; and
at least 0.250 to no more than 0.810 moles of a third acid comprising an alkyl acid with 7-9 carbons wherein the third acid has a lower molecular weight than the second acid; and
6-45 wt % surfactant; and
wherein the liquid has a BYV of at least 50 dyn/cm2.
4-40 wt % glyceride wherein the glyceride is the condensation reaction product of at least 1.10 moles of a mixture of acids to no more than 2.1 moles of mixture of acids per mole of glycerin;
wherein mixture of acids comprises:
at least 0.275 to no more than 0.990 moles of a first acid comprising a branched acid with 16-20 aliphatic carbons;
at least 0.250 to no more than 0.810 moles of a second acid comprising an alkyl acid with 9-11 carbons; and
at least 0.250 to no more than 0.810 moles of a third acid comprising an alkyl acid with 7-9 carbons wherein the third acid has a lower molecular weight than the second acid; and
6-45 wt % surfactant; and
wherein the liquid has a BYV of at least 50 dyn/cm2.
