Abstract
A topical composition, in particular a cosmetic composition, comprising, in a fatty phase, at least one wax and/or at least one nonvolatile liquid fatty substance, wherein the fatty phase contains at least one fluorosilicone compound. The composition exhibits good slip, non-tightness, softness and/or comfort properties as well as non-transfer and non-migration properties.
Claims15
A topical composition comprising a fatty phase, said fatty phase containing at least one volatile compound, at least one wax and at least one nonvolatile liquid fatty substance,
- wherein said fatty phase contains at least one fluorosilicone compound of formula (III):
- in which:
- R represents, or independently represents, in the case when n is greater than 1, a divalent methylene, ethylene, propylene or butylene group,
- m ranges from 0 to 80, and
- n ranges from 1 to 30,
- and wherein said at least one nonvolatile liquid fatty substance and said at least one wax are non-fluorinated compounds, and both said at least one nonvolatile liquid fatty substance and said at least one wax are selected so as to satisfy the following relationship:
- 0≦Δδ≦4
- in which:
- Δδ=[4×(δD non-fluoro wax−δD non-fluoro, nonvolatile liquid fatty substance)2+(δP non-fluoro wax−δP non-fluoro, nonvolatile liquid fatty substance)2+(δH non-fluoro wax−δH non-fluoro, nonvolatile liquid fatty substance)2]½
- wherein
- δD characterizes London dispersion forces arising from formation of dipoles induced during molecular impacts;
- δP characterizes the Debye forces of interaction between permanent dipoles;
- and
- δH characterizes forces of specific interactions, and further wherein said at least one nonvolatile liquid fatty substance, said at least one wax, or both said at least one nonvolatile liquid fatty substance and said at least one wax, which are selected to satisfy the relationship 0≦Δδ≦4, are selected so as to impart to the composition simultaneously good properties of non-transfer and comfort.
A process for limiting, decreasing, or preventing the transfer of a composition for making up, caring for, or both making up and caring for the skin, lips of the face, superficial body growths, or any combination thereof, said process comprising:
- introducing into said composition a fatty phase comprising at least one volatile compound, at least one wax, and at least one nonvolatile liquid fatty substance, wherein said fatty phase contains at least one fluorosilicone compound of formula (III):
- in which:
- R represents, or independently represents, in the case when n is greater than 1, a divalent methylene, ethylene, propylene or butylene group,
- m ranges from 0 to 80, and
- n ranges from 1 to 30, and wherein when at least one of said at least one nonvolatile liquid fatty substance and said at least one wax are non-fluorinated compounds, said at least one nonvolatile liquid fatty substance, said at least one wax, or both said nonvolatile liquid fatty substance and said wax are selected so as to satisfy the following relationship:
- 0≦Δδ≦4
- in which:
- Δδ=[4×(δD non-fluoro wax−δD non-fluoro, nonvolatile liquid fatty substance)2+(δP non-fluoro wax−δP nonfluoro, nonvolatile liquid fatty substance)2+(δH non-fluoro wax−δH non-fluoro, nonvolatile liquid fatty substance)2]½
- wherein
- δD characterizes London dispersion forces arising from formation of dipoles induced during molecular impacts;
- δP characterizes the Debye forces of interaction between permanent dipoles;
- and
- δH characterizes forces of specific interactions, and
- applying said composition to said skin, lips of the face, superficial body growths, or any combination thereof, to limit, decrease, or prevent the transfer of said composition from said skin lips of the face, superficial body growths, or any combination thereof.
