Abstract

A multi-layered cosmetic composition suitable for topical application is provided. The composition comprises an oil layer comprising at least about 5%, by weight of the composition, of natural oil; and an aqueous layer, comprising at least about 0.01%, by weight of the composition, of a polymer selected from the group consisting of a polysaccharide, sodium hyaluronate, or a combination thereof. The multi-layered cosmetic composition is free of surfactant.

First claim

What is claimed is:

1 . A multi-layered cosmetic composition suitable for topical application, comprising:
i) an oil layer comprising at least about 5%, by weight of the composition, of natural oil; and ii) an aqueous layer, comprising at least about 0.01%, by weight of the composition, of a polymer selected from the group consisting of a polysaccharide, sodium hyaluronate, or a combination thereof; wherein the multi-layered cosmetic composition is free of surfactant.

2 . A multi-layered cosmetic composition as claimed in claim 1 , wherein the aqueous layer comprises from about 0.01% to about 0.25% of said polymer.

3 . A multi-layered cosmetic composition as claimed in claim 1 or claim 2 , wherein said polysaccharide is xanthan gum.

4 . A multi-layered cosmetic composition as claimed in claim 3 , wherein said aqueous layer comprises from about 0.01% to about 0.25% of a combination of xanthan gum and sodium hyaluronate.

5 . A multi-layered cosmetic composition as claimed in any preceding claim, wherein the aqueous layer further comprises polyvinylpyrrolidone (PVP), polyethylene oxide, or a combination thereof.

6 . A multi-layered cosmetic composition as claimed in any preceding claim, wherein the natural oil comprises carry-over ingredients.

7 . A multi-layered cosmetic composition as claimed in any preceding claim, further comprising a silicone layer.

8 . A multi-layered cosmetic composition as claimed in any preceding claim, wherein the composition is intended for use as a moisturizer, toner, essence, serum, cream or any other known form of moisturizing or hydrating skin care composition.

9 . A multi-layered cosmetic composition suitable for topical application, comprising:
i) an oil layer comprising about 50% by weight of the composition of natural oil; and ii) an aqueous layer, comprising:
a) from about 0.01% to about 0.05% by weight of the composition of sodium hyaluronate; and
b) from about 0.01% to about 0.02% by weight of the composition of xanthan gum;

wherein the multi-layered cosmetic composition is free of surfactant.

10 . A multi-layered composition as claimed in claim 9 , further comprising from about 0.01% to about 1% by weight of the composition of polyvinylpyrrolidone (PVP).

11 . A multi-layered composition having a separation time of greater than 2 minutes post-agitation, the multi-layered composition comprising
i) an oil layer comprising at least 5% by weight of the composition of natural oil; and ii) an aqueous layer comprising at least 0.01% by weight of the composition of a polymer selected from: a polysaccharide, sodium hyaluronate, or a combination thereof; wherein the multi-layered cosmetic composition is free of surfactant.

12 . A method of applying a multi-layered cosmetic composition, comprising:
a) shaking a multi-layered composition to form an emulsion, said multi-layered composition having: i) an oil layer comprising at least 5% by weight of the composition of natural oil; and ii) an aqueous layer comprising at least 0.01% by weight of the composition of a polymer selected from the group consisting of a polysaccharide, sodium hyaluronate, or a combination thereof; wherein the multi-layered cosmetic composition is free of surfactant; b) applying said emulsified composition to a facial skin surface in need of treatment.
