Abstract: A fixative polymer is provided, comprising: structural units of monoethylenically unsaturated C1-12 alkyl (meth)acrylate monomer; structural units of monoethylenically unsaturated carboxylic acid containing monomer; structural units of monoethylenically unsaturated hydroxy functionalized C1-16 alkyl (meth)acrylate monomer; and structural units of carbosiloxane monomer of formula (I) wherein a is 0 to 3; wherein d is 0 or 1; wherein R1 is hydrogen, C1-10 alkyl, aryl, —OSi(R9)3 or —X—SiOSi(R9)3; wherein R2 and R9 are hydrogen or C1-10 alkyl; wherein R8 is —OSi(CH3)2OSi(CH3)3; wherein Y is formula (II), (III), (IV) or (V) wherein R4, R6 and R10 are hydrogen or C1-4 alkyl; wherein X, R3 and R5 are a divalent linking group; wherein R7 is a C1-10 alkyl group; wherein b is 0 to 4 and wherein c is 0 or 1.

Abstract: A silicone-(meth) acrylate copolymer and methods for the preparation and use of the copolymer are provided. The copolymer is soluble in ethanol under ambient conditions. The copolymer, or homogeneous ethanol solution thereof, may be used as a film forming agent in a personal care composition, such as a foundation.

Abstract: Described herein are emulsion polymers, spray dried powders made with said emulsion polymers, and cementitious compositions made with said emulsion polymers or said spray dried powders. Emulsion polymers described herein comprise a shell portion comprising an alkali soluble resin (ASR), a core portion formed from polymerized units of at least one hydrophobic ethylenically unsaturated monomer, wherein no crosslinker is present when the shell portion and core portion are combined, and a nonionic water-soluble polymer.

Abstract: Esterified cellulose ethers comprising groups of formula —C(O)—CHR?—CHR?—COOA, wherein, R? and R? are hydrogen or (—S)m(—R1)n-R2, wherein R1 is a hydrocarbon group having 1 to 4 carbon atoms, R2 is an optionally substituted 5- or 6-membered cyclic group, m and n each independently are 0 or 1, and A is hydrogen or a cation, with the proviso that in each group CHR?—CHR? one of R? and R? is hydrogen and the other one is (—S)m(—R1)n-R2, are useful as excipients for maintaining the concentration of poorly water-soluble drugs in aqueous liquids at supersaturation levels.
