    摘要: A personal care conditioning and/or styling composition for a keratin substrate comprising: (A) at least one conditioning and/or styling ter/tetra polymer obtained by polymerizing: (i) about 50 wt. % to 97 wt. % of at least one cationic or pseudo-cationic monomer selected from the group consisting of diallyl dimethyl ammonium chloride (DADMAC), Hydroxyethyl-pyrrolidone-methacrylate (MO6), and/or Vinylpyrrolidone (VP); (ii) about 1 wt. % to 30 wt. % of at least one anionic monomer selected from the group consisting of (a) acrylic acid (AA), (b) acrylamido methylpropyl sulfonate (AMPS), and/or (c) sodium methyl allyl sulfonate (SMAS); and (iii) about 0.1 wt. % to 20 wt. % of at least one hydrophobic monomer selected from the group consisting of (a) polyoxyethylene (PEG)-18-behenylether-methacrylate (BEM) (b) Lauryl-ethoxylated-methacrylate (LEM), (c) stearyl acrylate (SA), (d) Streath-10-allyl-ether, and/or (e) Vinylcaprolactam (V-cap); and wherein said ter/tetra polymer has a cationic degree of substitution (Cat-DS) of greater than about 0.001 units, and wherein the cationic charge density is in the range of about 1 meq/g to about 6.5 meq/g; (B) at least one cosmetically acceptable excipient; and (C) optionally, at least one effective amount of personal care active ingredient. Also, disclosed is a process of preparing said ter/tetra polymer, and its method of use.

    摘要: Disclosed herein is a water-soluble copolymer formed by copolymerizing N-vinylformamide and one or more vinyl C1-C10 alkyl esters, and then hydrolyzing from 30 to 100 mol % of the formyl groups from the copolymerized units to form amino groups and from 30 to 100 mol % of the C1-C10 alkyl ester groups from the copolymerized units to form hydroxyl groups, wherein the copolymer has a unimodal molecular weight distribution as evidenced by essentially one peak in a gel permeation gradient elution chromatographic analysis. A process to produce the polymer is also disclosed.

    摘要: The present invention is directed membrane active poly(vinyl ester) polymers and compositions for targeted delivery of RNA interference (RNAi) polynucleotides to cells in vivo. RNAi polynucleotides are conjugated to the poly(vinyl ester) polymers and the polymers are reversibly modified to enable in vivo targeted delivery. Membrane activity of the poly(vinyl ester) provides for movement of the RNAi polynucleotides from outside the cell to inside the cell. Reversible modification provides physiological responsiveness.
