Abstract
The present invention relates to a mono- and/or polyallyl-polyether-urethane, to water-soluble or water-dispersible polymers which comprise such a polyether-urethane in copolymerized form, and to cosmetic or pharmaceutical compositions which comprise a water-soluble or water-dispersible polymer based on a mono- and/or polyallyl-polyether-urethane.
Claims21
A hair treatment composition comprising water-soluble or water-dispersible polymer which comprises at least one free-radically polymerizable compound which has at least one α,β-ethylenically unsaturated double bond and at least a polyether-urethane in copolymerized form, where the polyether-urethane comprises at least one allyl group, and, in incorporated form,
- a) at least one polyalkylene glycol monoallyl ether having a number-average molecular weight in the range from 300 to 5000,
- b) optionally at least one compound which comprises at least two groups reactive toward isocyanate groups, and
- c) at least one polyisocyanate,
- as setting agent and/or as conditioner.
A polyether-urethane comprising at least one allyl group, which comprises, in incorporated form,
- a) at least one polyalkylene glycol monoallyl ether having a number-average molecular weight in the range from 300 to 5000,
- b) at least one compound chosen from compounds b3) wherein b3) is at least one compound chosen from:
- polysiloxanes of the formula I.1
- in which
- a and b, independently of one another, are 1 to 8,
- c is 2 to 100,
- R1 and R2, independently of one another, are C1-C8-alkyl, benzyl or phenyl,
- Z1 and R2, independently of one another, are OH, NHR3 or a radical of the formula II
- —(CH2CH2O)v(CH2CH(CH3)O)w—H (II),
- where
- in the formula II the alkylene oxide units can be in any order, and
- v and w, independently of one another, are an integer from 0 to 200, where the sum of v and w is >0,
- R3 is hydrogen, C1-C8-alkyl or C5-C8-cycloalkyl;
- polysiloxanes of the formula I.2
- in which
- the siloxane units can be in any order,
- the radicals R4 are each, independently of one another, C1-C8-alkyl,
- d is an integer from 5 to 1000,
- e is an integer from 2 to 100,
- f is an integer from 2 to 8,
- Z3 is OH, NHR3, where R3 is as defined above, or a radical of the formula III
- —(OCH2CH2)x(OCH(CH3)CH2)y—OH (III),
- where
- in the formula III the alkylene oxide units can be in any order,
- x and v independently of one another, are an integer from 0 to 200, where the sum of x and v is >0,
- and mixtures thereof,
- c) at least one polyisocyanate.
