A personal care conditioning and/or styling composition for a keratin substrate comprising: (i) about 50 wt. % to 95 wt. % of at least one cationic or pseudo-cationic monomer selected from the group consisting of acrylamidopropyl trimethylammonium chloride (APTAC) 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) Stream-10-allyl-ether, (e) Vinylcaprolactam (V-cap), and/or (f) Hydroxyethyl-pyrrolidone-methacrylate (M06). Also described is a process of preparing said polymer, and its method of use.

Personal care composition for a keratin substrate comprising conditioning and/or styling polymer

The invention relates to novel, stable bi-molecular cationic inverse emulsion polymers (W/O) with both different molecular weights and cationic activities that are assembled via an 'in situ' emulsion polymerization of a high molecular weight cationic polymer in the presence of a low molecular weight polymer in the aqueous phase. The low molecular cationic polymer is produced in a pre-polymerization in solution. The novel, stable cationic water-in-oil emulsion is easy invertible and useful as flocculant, dewatering aid and retention aid in papermaking.

The invention relates to water-in-water polymer dispersions containing cross-linked cationic polymers, methods for their preparation and their use. The water-in-water polymer dispersions are useful inter alia as flocculants, dewatering (drainage) aids and retention aids in papermaking.
