Patent ID: 8057786

Claim:
A cosmetic and/or dermatological composition comprising as an effective amount of a conditioning system: a) between 0.01-10.0 wt. % of a linear or branched modified starch polymer of the general formula where R 1 -R 11 are independently H or a hydroxyalkyl residue of the general formula â€”CH 2 â€”CHOHâ€”R 12 with R 12 being â€”CH 3 or â€”CH 2 NR 13 (CH 3 ) 2 + X âˆ’ with R 13 â•â€”CH 3 or a linear or branched C 4 -C 22 -alkyl residue and with X âˆ’ â•Cl âˆ’ , Br âˆ’ or I âˆ’ , where n is such that the average molecular weight of the polymer (I) is in the range of 200,000-1,000,000 Da and where the amount of hydroxyl groups carrying a cationic charge is between 25 wt. % and 50 wt. %, which corresponds to a degree of quaternization of D.S.=0.75 and 1.50 and b) between 0.01 and 10.0 wt. % of a linear or branched modified starch polymer of the general formula where R 1 -R 11 are independently H or a hydroxyalkyl residue of the general formula â€”CH 2 â€”CHOHâ€”R 12 with R 12 formula being â€”CH 3 or â€”CH 2 NR 13 (CH 3 ) 2 + X âˆ’ with R 13 â•â€”CH 3 or a linear or branched C 4 -C 22 -alkyl residue and with X âˆ’ â•Cl âˆ’ , Br âˆ’ or I âˆ’ , where m is such that the average molecular weight of the polymer (II) is in the range of 2,000,000-8,000,000 Da and where the amount of hydroxyl groups carrying a cationic charge is between 2 wt. % and 20 wt. %, which corresponds to a degree of quaternization of D.S.=0.06 and 0.60 in a cosmetic acceptable medium.
