Abstract

Disclosed is a skin care composition comprising: (1) from about 0.001% to about 10% of a flavonoid compound; (2) from about 0.01% to about 15% of a vitamin B3 compound; and (3) a dermatologically acceptable oil-in-water carrier comprising at least about 2% by weight of the entire composition of an oil component.

Claims

1. A skin care composition comprising:

(1) from about 0.001% to about 10% of a flavonoid compound selected from the group consisting of glucosyl hesperidin, glucosyl rutin, glucosyl myricitrin, glucosyl isoquercitrin, glucosyl quercitrin, methyl hesperidin, and mixtures thereof;

(2) from about 0.01% to about 15% of a vitamin B3 compound; and

(3) a dermatologically acceptable oil-in-water carrier comprising at least about 2% by weight of the entire composition of an oil component.

2. The composition of claim 1 further comprising from 0.001% to about 15% of a vitamin B6 compound.

4. The composition of claim 1 wherein the flavonoid compound is glucosyl hesperidin.

5. The composition of claim 1 wherein the carrier comprises:

(a) an oily component;

(b) an emulsifier;

(c) a viscosifying agent; and

(d) water.

6. The composition of claim 5 wherein the viscosifying agent comprises an acrylic polymer.

7. The composition of claim 5 further comprising a skin tone changing agent.

8. The composition of claim 1 wherein the carrier comprises:

(a) an emulsifier comprising two or more nonionic surfactants selected from the group consisting of polyoxyalkylene alkyl ether having the C_12-18 of alkyl substitute, polyoxyalkylene hydrogenerated castor oil, and a liner or branched, mono- or tri-alkyl glyceride;

(b) an oily component selected from the group consisting of hydrocarbon oils, fatty acid esters, silicone oils, and mixtures thereof;

(c) a viscosifying agent comprising carboxylic acid/carboxylate copolymer;

(d) a water soluble humectant; and

(e) water,

wherein the composition has an absorbent value of less than about 2 at a wave length of 340 nm.

9. The composition of claim 8, wherein at least one of the nonionic surfactants has an HLB of more than 10 and at least one of the nonionic surfactants has an HLB of less than 10.

3. (canceled)

10. A method of lightening the skin comprising the step of applying to the skin a composition comprising:

(1) from about 0.001% to about 10% of a flavonoid compound selected from the group consisting of glucosyl hesperidin, glucosyl rutin, glucosyl myricitrin, glucosyl isoquercitrin, glucosyl quercitrin, methyl hesperidin, and mixtures thereof;

(2) from about 0.01% to about 15% of a vitamin B3 compound; and

(3) a dermatologically acceptable oil-in-water carrier comprising at least about 2% by weight of the entire composition of an oil component.

11. A method of providing anti-aging benefit to the skin comprising the step of applying to the skin a composition comprising:

(1) from about 0.001% to about 10% of a flavonoid compound selected from the group consisting of glucosyl hesperidin, glucosyl rutin, glucosyl myricitrin, glucosyl isoquercitrin, glucosyl quercitrin, methyl hesperidin, and mixtures thereof;

(2) from about 0.01% to about 15% of a vitamin B3 compound; and

(3) dermatologically acceptable oil-in-water carrier comprising at least about 2% by weight of the entire composition of an oil component.
