Abstract
A topical formulation includes a water-soluble ingredient and an oil-soluble ingredient and includes a combination of water, a rheology modifier, and a water miscible organic solvent to stabilize the composition.
Claims2
A topical formulation with water-soluble and oil-soluble ingredients, said formulation comprising
- (a) 1.0% to 30% by weight of at least one water-soluble composition;
- (b) 1.0% to 25% by weight of at least one oil-soluble composition;
- (c) 1.0% to 15% by weight water;
- (d) 1.0% to 5% by weight of at least one rheology modifier;
- and,
- (e) 10% to 80% by weight of at least one water miscible organic solvent.

A method of forming a topical formulation including water-soluble ingredients and oil-soluble ingredients stabilized in said topical formulation, said method comprising the steps of
- (a) providing at least one water-soluble composition;
- (b) providing at least one oil-soluble composition;
- (c) providing water;
- (d) providing at least one water miscible organic solvent that admixes with water such that molecules of water occupy empty spaces among molecules of the organic solvent;
- (e) providing at least one rheology modifier to
- (i) absorb at least a portion of said water and of said water soluble composition dissolved in said water, and,
- (ii) form an emulsion with said oil-soluble composition;
- (f) admixing said water-soluble composition, said oil-soluble composition, said water, said water miscible organic solvent, and said rheology modifier such that
- (i) at least a portion of said water-soluble composition is dissolved by said water,
- (ii) at least a portion of said water is absorbed by said rheology modifier,
- (iii) said rheology modifier, including any of said water absorbed by said modifier, forms an emulsion with said oil-soluble composition, and
- (iv) at least a portion of said water mixes with said organic solvent such that molecules of said water occupy empty space among molecules of said organic solvent.
