Claims
- 1. A composition comprising at least one pulverulent material and at least one amide of formula (I) below:R1—CO—NH—R2 (I) in which R1 and R2, which are identical or different, denote a saturated or unsaturated, branched alkyl radical containing from 3 to 30 carbon atoms, wherein said at least one amide is present in an amount sufficient to homogeneously disperse said at least one pulverulent material in said composition.
- 2. A composition according to claim 1, wherein R1 and R2, which are identical or different, denote a saturated alkyl radical containing from 3 to 20 carbon atoms.
- 3. A composition according to claim 1, wherein R1 denotes a saturated alkyl radical containing from 3 to 10 carbon atoms.
- 4. A composition according to claim 1, wherein R2 denotes a branched radical of formula (II): wherein R3 and R4, which are identical or different, denote a linear alkyl radical containing from 1 to 27 carbon atoms, and wherein the total number of carbon atoms in the radical of formula (II) is less than or equal to 30.
- 5. A composition according to claim 4, wherein R3 and R4, which are identical or different, contain from 2 to 12 carbon atoms.
- 6. A composition according to claim 5, wherein R3 and R4, contain from 2 to 10 carbon atoms.
- 7. A composition according to claim 1, wherein said at least one pulverulent material is chosen from pigments, fillers and nacres.
- 8. A composition according to claim 1, wherein said at least one amide of formula (I) is present in an amount ranging from 0.1% to 50% by weight, relative to the total weight of the composition.
- 9. A composition according to claim 8, wherein said at least one amide of formula (I) is present in an amount ranging from 2 to 20% by weight, relative to the total weight of the composition.
- 10. A composition according to claim 1, wherein said at least one pulverulent material is present in an amount ranging from 0.1% to 80% by weight, relative to the total weight of the composition.
- 11. A composition according to claim 1, wherein said composition comprises a cosmetically acceptable support.
- 12. A composition according to claim 11, wherein said composition is in the form of a dispersion, an emulsion or a soft paste.
- 13. A composition according to claim 11, wherein said composition is in the form of a make-up composition, a skincare composition, a hair composition or an antisun composition.
- 14. A composition according to claim 1, wherein said at least one amide of formula (I) is a dispersing agent.
- 15. A dispersing agent for pulverulent materials comprising at least one amide of formula (I) below:R1—CO—NH—R2 (I) in which R1 and R2 independently denote a saturated or unsaturated, branched alkyl radical containing from 3 to 30 carbon atoms.
- 16. A process for dispensing at least one pulverulent material, said process comprising dispersing said at least one perverulent material in a composition comprising at least on amide of formula (I) below:R1—CO—NH—R2 (I) in which R1 and R2independently denote a saturated or unsaturated, branched alkyl radical containing from 3 to 30 carbon atoms.
