Abstract
The present disclosure relates to a cosmetic agent for treating keratin fibres, in particular human hair, wherein the cosmetic agent in a cosmetic carrier comprises a first polymer, which is a polyimide, and a second polymer, which is a film former, wherein the pH value of the cosmetic agent lies between about 2 and about 5 and the viscosity lies between about 8000 and about 25000 mPa s.
Claims21
A cosmetic agent for treating keratin fibres, wherein the cosmetic agent in a cosmetic carrier comprises
- (a) at least one first polymer comprising the structural units of formulas M1, M2 and M3
- wherein
- R1 is a group comprising oxyalkylene groups,
- R2 and R3 independently of one another are an alkyl group comprising from about 1 to about 3 C atoms,
- n is a number between from about 1 and about 5, and
- R4 and R5 independently of one another are hydrogen or an alkyl group comprising from about 1 to about 3 C atoms, with the proviso that either R4 and R5 are hydrogen or one of R4 and R5 is hydrogen, wherein
- x, y and z each lie between about 0.05 and about 0.95 parts wherein the sum of x, y and z is equal to about 1, and
- (b) at least one second polymer, which is a film former,
- wherein the pH value of the cosmetic agent is between about 2 and about 5, and the viscosity is between about 8000 and about 25000 mPa s, measured at 20° C. with a Brookfield viscometer DV-II, spindle 6 at 20 rpm.

A cosmetic agent for treating keratin fibres, wherein the cosmetic agent in a cosmetic carrier comprises
- (a) at least one first polymer comprising the structural units of formulas M1, M2 and M3
- wherein
- R1 is chosen from a group of general formula M4
- in which o and p are each a number between about 1 and about 50,
- R2 and R3 independently of one another are an alkyl group comprising from about 1 to about 3 C atoms,
- n is a number between from about 1 and about 5, and
- R4 and R5 independently of one another are hydrogen or an alkyl group comprising from about 1 to about 3 C atoms, with the proviso that either R4 and R5 are hydrogen or one of R4 and R5 is hydrogen,
- wherein x, y and z each lie between about 0.05 and about 0.95 parts wherein the sum of x, y and z is equal to about 1,
- wherein the first polymer is included in the cosmetic agent in an amount of from about 0.01 to about 2 wt. %, and
- (b) at least one second polymer, which is a film former, wherein the second polymer representing the film former is derived from the monomer units 1-vinyl-2-pyrrolidone and vinyl acetate, wherein the second polymer representing the film former is included in the cosmetic agent in an amount of from about 1 to about 9 wt. % in relation to the total weight of the cosmetic agent,
- wherein the pH value of the cosmetic agent is between from about 3 and about 4 and the viscosity is between 12000 and 16000, measured at 20° C. with a Brookfield viscometer DV-II, spindle 6 at 20 rpm.
