  • Publication number: 20140112966
    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. The use of such emulsions simultaneously allows there to be no obligation to use surfactants and organic solvents other than water, and allows the thickening phenomenon to be activated for pHs of less than 7: this latter characteristic is particularly advantageous for formulations intended to be used in contact with skin.

  • Patent number: 8461098
    Abstract: The invention pertains to a new method for formulating active fragrance ingredients in such a way as to protect them and to slow the evaporation method of said active ingredients. It relies upon the use of thickening acrylic emulsions, at a pH above 5 and containing hydrophobic groups in order to trap said active ingredients. The invention also pertains to various methods of realizing the active ingredients thus formulated: a mixture in water of these active ingredients with thickening emulsions, dispersion of solid particles of these polymers and of these active ingredients after acidification, and solid particles obtained in a dry state after water is eliminated. Finally, the invention pertains to the use of these various formulations in order to protect an active ingredient and slow its evaporation kinetic.
