Bodywash additives
View Patent ↗The invention encompasses additives for addition to a composition for topical application, e.g., a bodywash, where the additive contains an encapsulated non-sunscreen, and methods of making and using the additives as well as topical compositions containing the additives. The additive may be encapsulated in a sol-gel microcapsule, and, in some cases, also includes a cationic polymer.
1. An additive for addition to a bodywash, wherein the additive comprises a non-sunscreen active that is encapsulated in a sol-gel microcapsule, a film former, and a cationic polymer.
2. The additive of claim 1 wherein the cationic polymer is a polyquatemium.
3. The additive of claim 2 wherein the polyquatemium is polyquaternium-4, -7, -11, -22, -27, -44, -51, or -64.
4. The additive of claim 3 , wherein the cationic polymer is polyquatemium-4.
5. The additive of claim 1 wherein the film former comprises petrolatum.
6. The additive of claim 1 further comprising a preservative.
7. The additive of claim 1 further comprising an antioxidant that is stable upon exposure to sunlight.
8. The additive of claim 1 wherein the sol-gel microcapsule is silica or modified silica.
9. The additive of claim 1 comprising at least two non-sunscreen actives.
10. The additive of claim 1 wherein the non-sunscreen active is selected from the group consisting of steroidal anti-inflammatory actives, analgesic actives, antifungals, antibacterials, and antiparasitics, anti-allergenics, medicinal actives, skin rash, skin disease and dermatitis medications, insect repellant actives, antioxidants, hair growth promoter, hair growth inhibitor, hair bleaching agents, deodorant compounds, and mixtures and combinations thereof.
11. The additive of claim 1 wherein the active comprises an agent that is effective in counteracting the effects of chemical, radiological, or biological agents on the skin.
12. An additive for addition to a bodywash, wherein the additive comprises sol-gel microcapsules that do not contain any active ingredients, a film former, and a cationic polymer.
13. The additive of claim 12 wherein the sol-gel microcapsules provide a physical barrier to protect the skin.
14. A bodywash comprising an additive, wherein the additive comprises a non-sunscreen active encapsulated in a sol-gel microcapsule, a film former, and further comprises a cationic polymer.
15. The composition of claim 14 wherein the cationic polymer is a polyquaternium.
16. The composition of claim 15 wherein the polyquaternium is polyquaternium-4, -7, -11, -22, -27, -44, -51, or -64.
17. The composition of claim 16 , wherein the cationic polymer is polyquaternium-4.
18. The composition of claim 14 wherein the film former comprises petrolatum.
19. The composition of claim 14 further comprising a preservative.
20. The composition of claim 14 further comprising an antioxidant that is stable upon exposure to sunlight.
21. The composition of claim 14 comprising at least two non-sunscreen actives.
22. The composition of claim 14 wherein the non-sunscreen active is selected from the group consisting of steroidal anti-inflammatory actives, analgesic actives, antifungals, antibacterials, and antiparasitics, anti-allergenics, medicinal actives, skin rash, skin disease and dermatitis medications, insect repellant actives, antioxidants, hair growth promoter, hair growth inhibitor, hair bleaching agents, deodorant compounds, and mixtures and combinations thereof.
23. The composition of claim 14 wherein the active comprises an agent that is effective in counteracting the effects of chemical, radiological, or biological agents on the skin.
24. The composition of claim 1 wherein the non-sunscreen active is a humectant selected from the group consisting of urea, guanidine, sorbitol, hexanetriol, propylene glycol, hexylene glycol, polyethylene glycol, sugars, starches, sugar derivatives, starch derivatives, D-panthenol, hyaluronic acid, lactamide monoethanolamine, acetamide monoethanolamine, and mixtures thereof.
25. The composition of claim 1 wherein the additive is an antiwrinkling agent selected from the group consisting of botox, octanoyl salicylate, mandelic acid, glyceric acid, N-acetyl-L-cysteine, lipoic acid, thiols, ethane thiol, ceramides, pseudoceramides, phospholipids, fatty acids, fatty alcohols, cholesterol, plant sterols, phytic acid, lysophosphatidic acid, phenol, and mixtures thereof.
