## Abstract

The invention relates to a thickening composition intended for topical application on the skin, lips or skin appendages, said thickening composition comprising at least one oil derived from a biological source and at least one poly(farnesene) polymer having a number average molar mass ranging from 10,000 to 120,000 g/mol. The invention also relates to a cosmetic composition comprising the thickening composition according to the invention and the use of the thickening composition according to the invention in a cosmetic composition.

## Claims

### Claim 1

A thickening composition intended for topical application on the skin, lips or skin appendages, said thickening composition comprising:
at least one oil derived from a biological source, and
at least one poly(farnesene) polymer having a number average molar mass ranging from 10,000 to 120,000 g/mol, said poly(farnesene) polymer being partially or fully hydrogenated and/or functionalised with hydroxyl groups,
wherein the at least one oil derived from a biological source is a hydrocarbon oil comprising, based on the total weight of the hydrocarbon oil, greater than or equal to 90% by weight of isoparaffinic compounds.

### Claim 2 (depends on 1)

The thickening composition according to claim 1, wherein the oil derived from a biological source is selected from among hydrocarbon oils, plant or animal oils in the form of acids, esters or amides, and mixtures thereof.

### Claim 3 (depends on 1)

The thickening composition according to claim 1, wherein the oil derived from a biological source is a hydrocarbon oil.

### Claim 4 (depends on 3)

The thickening composition according to claim 3, wherein the hydrocarbon oil is selected from among non-cyclic isoparaffins comprising from 14 to 18 carbon atoms.

### Claim 5 (depends on 3)

The thickening composition according to claim 3, wherein the hydrocarbon oil comprises:
a content by weight of isoparaffins, ranging from 95 to 100% relative to the total weight of the hydrocarbon oil; and/or
a content of carbon derived from biological sources that is greater than or equal to 95%; and/or
a content by weight of normal paraffins that is less than or equal to 10, relative to the total weight of the hydrocarbon oil; and/or
a content by weight of naphthenic compounds that is less than or equal to 1%, relative to the total weight of the hydrocarbon oil; and/or
a content by weight of aromatic compounds that is less than or equal to 500 ppm, relative to the total weight of the hydrocarbon oil.

### Claim 6 (depends on 3)

The thickening composition according to claim 3, wherein the hydrocarbon oil is obtained by a method of catalytic hydrogenation at a temperature of 80 to 180° C., and at a pressure of 50 to 160 bars of a deoxygenated and/or isomerised biologically-sourced feedstock.

### Claim 7 (depends on 1)

The thickening composition according to claim 1, wherein the poly(farnesene) polymer has a number average molar mass ranging from 20,000 to 90,000 g/mol.

### Claim 8 (depends on 1)

The thickening composition according to claim 1, comprising, relative to the total weight of the thickening composition:
from 10 to 90% by weight of oil(s) derived from biological sources; and
from 10 to 90% by weight of poly(farnesene) polymer(s).

### Claim 9 (depends on 1)

The thickening composition according to claim 1, that is selected from a thickening agent, sensory agent, film-forming agent, texturing agent, water resistance enhancing agent, moisturising/hydrating agent, conditioner, viscous oil, or agent that provides a second skin effect, in a cosmetic composition.

### Claim 10 (depends on 1)

A cosmetic composition for topical cosmetic application on the skin, lips or skin appendages, said cosmetic composition comprising at least one thickening composition according to claim 1.

### Claim 11 (depends on 10)

The cosmetic composition according to claim 10, comprising at least one fatty substance selected from among: plant oils, where appropriate other than the plant oils of said thickening composition, hydrocarbon oils, where appropriate other than the hydrocarbon oil of said thickening composition; plant butters; fatty ethers and fatty alcohols; oily esters; alkanes and silicone oils; and/or at least one additive.

### Claim 12 (depends on 10)

The cosmetic composition according to claim 10 that is selected from a care product for the skin or the hair, a makeup product, a hair product, a makeup removal product, a perfumed product, a sunscreen product, a lip care product.

### Claim 13 (depends on 1)

A cosmetic treatment process for the cosmetic treatment of the skin, lips or skin appendages, comprising at least one step of applying the thickening composition according to claim 1 or a cosmetic composition for topical application on the skin, the lips or skin appendages comprising the thickening composition.

### Claim 14 (depends on 1)

A sunscreen composition for topical application, said sunscreen composition comprising (i) at least one sunscreen filter, and (ii) at least one thickening composition according to claim 1.

### Claim 15 (depends on 3)

The thickening composition according to claim 3, wherein the hydrocarbon oil comprises a content by weight of isoparaffins ranging from 90 to 100%, a content by weight of normal paraffins ranging from 0 to 10%, relative to the total weight of the hydrocarbon oil.

### Claim 16 (depends on 10)
