## Abstract

Provided is a composition, especially a cosmetic composition, that comprises at least one monoglyceride and at least one tartaric ester of monoglyceride, and at least one coated pigment and/or mineral filler. Also provided is the use of a coated pigment and/or coated mineral filler for improving the stability of a composition, especially a cosmetic composition comprising at least one monoglyceride and at least one diacetyl tartaric ester of monoglyceride. Further provided is a cosmetic treatment method that implements the composition of the invention.

## Claims

### Claim 1

A cosmetic treatment method for limiting the gloss or shiny appearance of the skin and/or providing a skin hydration effect, said method comprising applying a composition on an area of skin of a subject in need of limiting the gloss or shiny appearance of the skin and/or providing a skin hydration effect, said composition comprising an aqueous phase and at least one coated pigment and/or at least coated mineral filler, said composition further comprising a lipogel phase comprising (i) at least one monoglyceride and (ii) at least one tartaric ester of monoglyceride, wherein the at least one monoglyceride comprises a saturated or unsaturated alkyl chain of 12 to 22 carbon atoms and wherein the monoglyceride content is from 1% to 20% by mass based on the total mass of said composition and wherein the tartaric ester of monoglyceride content is from 0.1% to 1% by mass based on the total mass of said composition, wherein said composition limits the gloss or shiny appearance of the skin and/or provides a skin hydration effect at the area of application of said composition.

### Claim 2 (depends on 1)

The cosmetic treatment method, according to claim 1, wherein said method is for limiting the gloss or shiny appearance of the skin in a tropical climate at the area of application of said composition.

### Claim 3 (depends on 1)

The cosmetic treatment method, according to claim 1, wherein the composition comprises more than 50% in mass of aqueous phase relative to the total mass of the composition.

### Claim 4 (depends on 1)

The cosmetic treatment method, according to claim 1, wherein the monoglyceride comprises a saturated or unsaturated alkyl chain of 16 or 18 carbon atoms.

### Claim 5 (depends on 1)

The cosmetic treatment method, according to claim 1, wherein the tartaric ester of monoglyceride is a diacetyl tartaric ester of monoglyceride comprising a saturated or unsaturated alkyl chain of 12 to 22 carbon atoms.

### Claim 6 (depends on 1)

The cosmetic treatment method, according to claim 1, wherein the at least one coated pigment and/or the at least coated mineral filler is coated with at least one hydrophobic or lipophilic-treating agent selected from silicone surfactants; fluorinated surfactants; fluorosilicone surfactants; metal soaps amino N-acylamino acids or salts thereof; lecithin and its derivatives; triisostearyl isopropyl titanate; isostearyl sebacate; plant or animal natural waxes, synthetic waxes polar; fatty esters; fatty alcohols; phospholipids; and mixtures thereof.

### Claim 7 (depends on 1)

The cosmetic treatment method, according to claim 1, wherein the coated content of the at least one coated pigment and/or the at least coated mineral filler is from 0.1% to 4% by mass based on the total mass of said composition.

### Claim 8 (depends on 6)

The cosmetic treatment method according to claim 6, wherein the hydrophobic or lipophilic-treating agent represent from 0.1 to 50% by mass of the total mass of the coated pigment and the coated mineral filler.

### Claim 9 (depends on 1)

The cosmetic treatment method according to claim 1, wherein the composition comprises a least one sequestering agent.

### Claim 10 (depends on 1)

The cosmetic treatment method according to claim 1, wherein the composition comprises a least one sequestering agent selected from ethylene diamine tetraacetic acid (EDTA), glucono delta-lactone, sodium gluconate, potassium and/or calcium; citric acid, phosphoric acid, tartaric acid, potassium bitartrate, sodium acetate, sorbitol and any combination thereof.

### Claim 11 (depends on 1)

The cosmetic treatment method, according to claim 1, wherein the composition comprises a sequestering agent from 0.01% to 1% by mass based on the total mass of said composition.
