Sprayable composition comprising high molecular weight charged polymer
View Patent ↗Disclosed herein are sprayable compositions comprising: a complex of (A) at least one charged (or pseudo-charged) polymer having a molecular weight of about 125,000 amu or more; and (B) a least one oppositely charged, rheology modifying, crosslinked polymer having at least one carboxylic functional group. The composition may provide a spray with a median particle size of less than about 175 μm. Also disclosed are methods for preparing the compositions as well as creating the spray. The invention enables the spray of the high molecular weight charged (or pseudo-charged) polymer in any number of uses including personal care and performance chemicals application.
1. A sprayable composition comprising: a complex of
(A) at least one anionic, pseudo-anionic, cationic or pseudo-cationic polymer having a molecular weight of 250,000 amu or more; and (B) at least one cationic, pseudo-cationic, anionic or pseudo-anionic rheology modifying crosslinked polymer having at least one carboxylic functional group, wherein, said complex is selected from the group consisting of:
(i) poly(N-vinyl-2-pyrrolidone-co-dimethylaminopropylmethacrylamide) copolymer and poly(N-vinyl-2-pyrrolidone-co-acrylic acid) crosslinked copolymer;
(ii) PQ-55 and poly(N-vinyl-2-pyrrolidone-co-acrylic acid) crosslinked copolymer;
(iii) poly(N-vinyl-2-pyrrolidone-co-dimethylaminopropylmethacrylamide) copolymer and poly(maleic anhydride-co-methylvinylether) 1,10-butadiene crosslinked copolymer;
(iv) poly(N-vinyl-2-pyrrolidone-co-dimethylaminopropylmethacrylamide) copolymer and crosslinked polyacrylates; and
(v) poly(N-vinyl-2-pyrrolidone-co-dimethylaminoethyl methacrylate) copolymer and poly(N-vinyl-2-pyrrolidone-co-acrylic acid) crosslinked copolymer,
wherein, said sprayable composition provides a spray with a median droplet size, dv(50), of less than about 175 μm.
