Preparation containing a water soluble or water dispersible copolymer obtainable by radical copolymerization useful as a cosmetic or pharmaceutical preparation, a protective colloid, and in the textile-, paper-, or printing industries

摘要

A cosmetic or pharmaceutical preparation containing a water soluble or water dispersible copolymer (A) obtainable by radical copolymerization of: (1) (meth)acrylic acid amide; (2) alpha-beta-ethylenically unsaturated amide group containing compounds starch, starch derivatives and their mixtures; and (3) at least one cosmetically acceptable carrier is new. A cosmetic or pharmaceutical preparation containing: (1) at least one water soluble of water dispersible copolymer (A) obtainable by radical copolymerization of (wt.%): (a) (meth)acrylic acid amide (5-90); (b) at least one alpha-beta-ethylenically unsaturated amide group containing compounds of formula R1-C(O)-NR2R3 (I) (0-85): (c) at least one component different from (a) and (b) with a copolymerisable unsaturated water soluble compound (0-40), where the sum of (b) and (c) is at least 5 wt.%, optionally in the presence of up to 25 wt.% on the total weight of components (a) and (b) of at least one water soluble component (d) selected from: (i) polyether containing compounds; (ii) polymers having at least one 50 wt.% repeating units derived from vinyl alcohol; and (iii) starch and starch derivatives and their mixtures; and (2) at least one cosmetically acceptable carrier. R1, R2 = CH2=CR4; R4 = H or 1-4C alkyl; R1, R2, R3 = H, alkyl, cycloalkyl, heterocycloalkyl, aryl or heteroaryl; provided that: (1) either R1 is CH2=CR4 and R2 is H, alkyl, cycloalkyl, heterocycloalkyl, aryl or heteroaryl or joined with R3 or R2 is C=R4 and R1 is H, alkyl, cycloalkyl, heterocycloalkyl, aryl or heteroaryl or joined with R3; and (2) both of R2 and R3 are not H. An Independent claim is also included for a copolymer A obtainable by radical polymerization of (wt.%)::(a) methacrylic acid amide (10-45) and (b) vinylpyrrolidone and/or vinylcaprolacatam (60-90), (c) at least one different from (a) and (b) copolymerisable unsaturated water soluble compound (0-25), optionally in the presence of up to 25 wt.% on the total weight of (a)-(d) of polymers (d2) and/or starch or starch derivatives.
