Abstract: The invention relates to novel biosourced polyamide derivatives able to form gels, the method for preparing same, the gels formed from these gelling polyamides, as well the compositions containing them, in particular cosmetic compositions.

Abstract: The invention relates to new oil gelling polyurethanes useful for preparing clear gels in organic media (oils, solvents) and to a process for their preparation. The invention also relates to the gels formed from these gelling polyurethanes and to compositions containing them, in particular cosmetic compositions.

Abstract: The invention relates to an aqueous viscoelastic solution comprising: at least one polymer selected from among hyaluronic acid and the salts thereof, and cellulosic derivatives and the salts thereof, in particular hydroxypropyl methylcellulose and the salts thereof; and at least one water-soluble polymer of the polyether-polyurethane or polyether-polyester-urethane type, and to the use thereof in a device intended for the injection of an intraocular implant.

Abstract: The invention relates to an intraocular lens comprising at least one pharmaceutically-acceptable photochromic polymer that enables all or part of the intraocular lens to change colour reversibly when exposed to light.

Abstract: The invention relates to a sizing composition intended to be applied to mineral fibers, especially glass or rock fibers, which contains at least one polycarboxylic acid and at least one polyamine. It also relates to a method of preparing the composition, to its use for sizing mineral fibers for the purpose of forming, in particular, thermal and/or acoustic insulation products, and to the products obtained.

Abstract: The invention relates to a composition for treating and/or preventing snoring, comprising at least one thermogelling polymer that includes water-soluble units as well as units having a lower critical demixing temperature in water. Said composition has the specific feature of being liquid in the packaging thereof and becoming a gel upon contacting mucus membranes at 37° C. Thermogelling makes it possible to precisely target the area to be treated while avoiding any running or migration of the material, and makes the sprayed composition difficult to wash off, thus increasing the duration of the presence thereof in the treatment area.

Abstract: The invention relates to novel compounds of formula (I): in which R1, R2 and R3, identical or different, independently represent: hydrogen a halogen a C1 to C15 hydroxy or hydroxyalkyl group a C1 to C15 linear or branched alkyl group a, b and c independently lying between 0 and 5. R4 is linked to the naphthalene unit at position 1, 2 or 3 via a —CH2—O— bond and represents: either a divalent group which is (co)polymerisable with a monomer; in which case d lies between 1 and 3 or a monovalent group which is (co)polymerisable with a monomer; in which case d is equal to 2 or 3 and R5 is linked to the naphthalene unit at position 1, 2 or 3 and represents: hydrogen, a halogen, a C1 to C15 hydroxyalkyl group, a C1 to C15 linear or branched alkyl group, and e is an integer lying between 0 and 2 and such that d+e=3. It also relates to the method for synthesising these compounds and to their use for the manufacture of photochromic or photosensitive polymers.

Abstract: Polymers which comprise polymer chains of terpolymer type which are constituted by poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) of PEO-PPO-PEO form, which are modified at their termini by groups which can essentially be other chains of PEO-PPO-PEO, acid segments, amine groups or PEOs, these chains being linked to the terpolymer chains via chemical bridges which are constituted by urethane bridges, urea bridges, allophanate bridges and biuret bridges, and which comprise more than 80% by weight of said PEO-PPO-PEO. Thermoreversible physical gels of high viscosification index, which contain these polymers, and their uses. Preparation of these polymers and of these gels.
