Abstract

Compositions for topical application that effectively deliver antioxidants across the epidermis, dermis, or a combination thereof into cells and/or the bloodstream while concurrently maintaining chemical activity of the antioxidants. In certain aspects, these formulations include emulsions and balms each having a lipophilic carrier and a lipophilic antioxidant solubilized by the lipophilic carrier. Also disclosed herein are methods for making these compositions for topical application.

Claims (13)

1. A method of making a topical composition comprising:

mixing a lipophilic antioxidant comprising at least one phenyl group and a lipophilic carrier to create a butter and heating to 230-275° F. for about five minutes;

mixing water and glycerin in a container and heating to between 150-200° F. to create a water-glycerin mixture;

mixing the butter with a surfactant, a mineral oil, a paraffinic oil, an antioxidant, a skin penetration enhancer and heating to between 150-200° F. to create an oil-based mixture;

mixing a preservative with a fragrance to create a preservative mixture;

mixing the water-glycerin mixture with the oil-based mixture to create an emulsion and reducing temperature; and

mixing in the preservative mixture once temperature has reached about 160° F. and cooling to room temperature.

2. The method of claim 1 wherein the lipophilic antioxidant is pentaerythritol tetrakis (3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate).

3. The method of claim 1 wherein the lipophilic carrier is avocado butter.

4. The method of claim 1 wherein the paraffinic oil is petrolatum.

5. The method of claim 1 wherein the antioxidant is vitamin E.
