Abstract: The present invention concerns a method for determining the concentration of cationic polymers present in a sample, according to the following steps: —bringing the cationic polymer or polymers present in the sample into contact with, and enabling the interaction thereof with, a developer solution comprising lanthanide (III) ions and at least one bonding agent, and —exciting the sample at an excitation wavelength ?exc and detecting, by time resolved photoluminescence, a signal originating from the lanthanide (III) ions having interacted with the at least one bonding agent having previously interacted with the cationic polymer or polymers, at an emission wavelength ?em, and —determining the cationic polymer concentration of the sample by using the signal detected at the emission wavelength ?em, the sample originating from water originating from municipal or industrial water or sludge treatment processes.

Abstract: The present invention relates to a method for determining the anionic charge density of at least one polymer present in a sample, according to the following steps: bringing the at least one polymer present in the sample into contact with, and enabling the interaction thereof with, a developer solution comprising lanthanide (III) ions, exciting the sample at an excitation wavelength ?exc and detecting, by time-resolved photoluminescence, a signal originating from the lanthanide (III) ions that have interacted with the at least one polymer at an emission wavelength ?em, and determining the anionic charge density of the at least one polymer of the sample using the signal detected at the emission wavelength ?em.

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.

Abstract: The present invention concerns the use of a specific copolymer to homogenize compositions that include coloring pigments and/or pearlescent pigments and film-forming polymers, as well as the cosmetic compositions containing said copolymer.

Abstract: Cosmetic compositions for make-up containing acrylic comb copolymers having the advantage of increasing the intensity of the color produced by these compositions when they are applied to the skin or to keratin derivatives such as the hair or the eyelashes. Not only are the aesthetic properties conferred by these compositions thus improved, but their useful life is also increased, since they allow access to the desired shade (and good intensity) right from the first application.
