Claims
- 1. A skin moisturizer composition comprising:
(A) from about 25 to 99.95% of a liquid crystal gel network comprising:
(a) water, (b) at least one low HLB nonionic coemulsifier, and (c) at least one high HLB nonionic primary emulsifier, the concentration of (A)(b) plus (A)(c) being from about 0.1 to about 20%; (B) From about 0.05 to about 25% of an oil controlling agent, and (C) From about 0 to about 75% of one or more ingredients selected from the group of active agents, adjuvants and excipients, all percentages being by weight of the total composition, said composition having a surface tension of 25 mN/M or less.
- 2. The composition of claim 1 wherein the ratio of the component (A)(b) to component A(c) is from about 40:1 to 1:1.
- 3. The composition of claim 1 wherein the liquid crystal gel netweork is present in the composition in an amount of from about 50 to 95%, with the combined concentration of component (A)(b) plus (A)(c) being from about 0.5% to about 15%.
- 4. The composition of claim 3 wherein the ratio of the component (A)(b) to component A(c) is from about 40:1 to 1:1.
- 5. The composition of claim 1 wherein the oil control agent is selected from the group consisting of starch, hydrophobically modified starch, calcium silicate, clay, polymer powder, cross-linked hydrophobic acrylate or methacrylate copolymers, and modified protein derivatives.
- 6. The composition of claim 5 wherein the preferred oil controlling agent is selected from aluminum starch octenyl succinate, sodium C8-16 isoalkyl succinyl soy protein succinate, and mixtures thereof.
- 7. The composition of claim 1 wherein the nonionic coemulsifier (A)(b) is selected from the group consisting of fatty acids, fatty alcohols, glyceryl esters, and mixtures thereof.
- 8. The composition of claim 1 wherein the nonionic primary emulsifier is lecithin.
- 9. The composition of claim 1 wherein the component (C) is an emollient oil/wax present in an amount of from about 0.1 to 20% by weight of the total composition.
- 10. The composition of claim 1 wherein the component (C) is a thickening agent present in an amount of from about 0.1 to 10% by total weight of the composition.
- 11. The composition of claim 10 wherein the thickener is selected from the group consisting of polyacrylamides, xanthan gum and magnesium aluminum silicate.
- 12. The composition of claim 1 wherein the component (C) is a humectant.
- 13. The composition of claim 6 wherein the nonionic emulsifier (A)(b) is selected from the group consisting of fatty acids, fatty alcohols, glyceryl acids, and mixtures thereof, wherein the nonionic primary emulsifier (A)(c) is a phospholipid.
- 14. The composition of claim 13 wherein the surface tension of the composition is less than about 22 mN/M.
- 15. The composition of claim 13 wherein the surface tension of the composition is less than about 20 mN/M.
