Abstract
A cosmetic composition for the hair and/or skin comprising a water-dispersible sulfone copolyester with polyorganosiloxane units incorporating a plurality of recurrent sulfone polyester units and polyorganosiloxane units which have: a molecular mass number between 5000 and 45,000; a sulfur weight content of 0.5 to 6% compared with the said sulfone copolyesters with polyorganosiloxane units; and a silicium content of 0.05 to 20% by weight compared with the said sulfone copolyesters with polyorganosiloxane units.
Claims18
A cosmetic hair or skin composition comprising at least one water-dispersible sulfonated copolyester containing polyorganosiloxane units having a plurality of repeating sulfonated polyester units and polyorganosiloxane units, said sulfonated copolyester containing polyorganosiloxane units having:
- a number-average molecular mass from about 5000 to 45,000,
- a weight content of sulfur from about 0.5 to 10%, relative to said sulfonated copolyesters containing polyorganosiloxane units, and
- a silicon content from about 0.05 to 20% by weight relative to said sulfonated copolyesters containing polyorganosiloxane units;
- said composition comprising:
- from about 0.1 to 50% of its weight of said sulfonated copolyester containing said polyorganosiloxane units, and
- from about 0.5 to 99.5% of its weight of a vehicle compatible with the hair or the skin.
