  • METHOD FOR THICKENING A COSMETIC FORMULATION USING AN ALKALI SWELLABLE EMULSION OF A POLYMER WITH AMPS AND WHICH IS RICH IN ACRYLIC ACID
    Publication number: 20170027846
    Abstract: Process for thickening a composition, through the use of a direct emulsion in water, which is alkali-swellable, of a polymer of the ASE or HASE type, which is both rich in acrylic acid and which has a certain quantity of AMPS.

  • Amphiphilic and non-water soluble (meth)acrylic comb polymers
    Patent number: 9359463
    Abstract: Non water-soluble polymers with a comb structure and a (meth)acrylic skeleton on which are grafted side chains containing at least one hydrophobic monomer of the styrene or (meth)acrylic ester type on C1 to C4, and at least one hydroxy or methoxy polylakylene glycol monomer. The levels of monomers are such that the polymer is amphiphilic because it is both rich in hydrophobic monomer and polylakylene glycol monomer. These products, used in paper coating dispersions, enable an increase in their Brookfield™ viscosity, a reduction in their ACAV viscosity, and an improvement in their water retention, which makes them particularly well suited for dry extract and/or high deposit speed coatings.
