Compositions comprising superhydrophilic amphiphilic copolymers and methods of use thereof
View Patent ↗Provided are compositions comprising a superhydrophilic amphiphilic copolymer and a carrier and composition comprising a superhydrophilic amphiphilic copolymer, a micellar thickener and a carrier.
1. A composition comprising a carrier and a superhydrophilic amphiphilic copolymer comprising a starch-based or cellulose-based polysaccharide modified with a hydrophobic reagent comprising at least one 3-chloro-2-hydroxypropylalkyldimethylammonium chloride, wherein the superhydrophilic amphiphilic copolymer comprising the starch-based or cellulose-based polysaccharide modified with the hydrophobic reagent comprising at least one 3-chloro-2-hydroxypropylalkyldimethylammonium chloride has a weight average molecular weight that is less than about 200,000 and a solution viscosity of less than about 9 centipoise, wherein the superhydrophilic amphiphilic copolymer modified with the hydrophobic reagent comprising at least one 3-chloro-2-hydroxypropylalkyldimethylammonium chloride is prepared by forming an aqueous solution of the starch-based or cellulose-based polysaccharide in water by dissolving from about 25% to about 75% of the starch-based or cellulose-based polysaccharide in water, based on total weight of the aqueous solution, to produce the aqueous solution comprising the starch-based or cellulose-based polysaccharide, adding the hydrophobic reagent comprising at least one 3-chloro-2-hydroxypropylalkyldimethylammonium chloride to the aqueous solution, and reacting the hydrophobic reagent comprising at least one 3-chloro-2-hydroxypropylalkyldimethylammonium chloride with the starch-based or cellulose-based polysaccharide dissolved in the aqueous solution at a pH of 11.5 or greater to form an aqueous solution of the superhydrophilic amphiphilic copolymer comprising the starch-based or cellulose-based polysaccharide modified with the hydrophobic reagent comprising at least one 3-chloro-2-hydroxypropylalkyldimethylammoniumchloride.
2. The composition of claim 1 , wherein the superhydrophilic amphiphilic copolymer has a mole percent of amphiphilic repeat units that is from about 1 to about 8.5.
3. The composition of claim 1 , wherein the superhydrophilic amphiphilic copolymer has a DP between 4 and about 500.
4. The composition of claim 1 , wherein the superhydrophilic amphiphilic copolymer has a Dynamic Surface Tension Reduction, t γ=55 , of less than about 120 seconds.
5. The composition of claim 1 wherein the superhydrophilic amphiphilic copolymer has a PMOD % of less than about 90%.
6. The composition of claim 1 wherein said superhydrophilic amphiphilic copolymer is a starch-based polysaccharide derived from potato or tapioca.
7. The composition of claim 1 wherein said carrier is a cosmetically-acceptable carrier.
