Abstract (en)
[origin: US2011129540A1] The present invention relates to a novel family of polymers of acrylic and/or methacrylic type, comprising alpha-tocopherol grafts, capable of forming nanoparticles in an aqueous medium at a neutral pH. It also relates to the use of such nanoparticles, non-covalently combined with an active ingredient, in particular an active ingredient of low or average aqueous solubility, for conveying, solubilizing and/or increasing the aqueous solubilization of said active ingredient.
