Title (EN) MOISTURIZING PERSONAL CARE COMPOSITIONS COMPRISING MONODISPERSE PHYTOGLYCOGEN NANOPARTICLES AND A FURTHER POLYSACCHARIDE
(FR) COMPOSITIONS DE SOINS PERSONNELS HYDRATANTES COMPRENANT DES NANOPARTICULES DE PHYTOGLYCOGÈNE MONO-DISPERSÉES ET UN AUTRE POLYSACCHARIDE
Abstract:
(EN) Compositions comprising monodisperse phytoglycogen nanoparticles and a further moisturizing polysaccharide are disclosed as exhibiting a synergistically enhanced ability to moisturize the skin. Preferably, the phytoglycogen is isolated from plant matter such as sweet corn kernels. The moisturizing polysaccharide may be a glycosaminoglycan, a chitosan, an alginate, or a beta glucan. In preferred embodiments, the polysaccharide is hyaluronic acid. The compositions may optionally further comprise various carriers, fillers, and active agents.
(FR) L'invention concerne des compositions comprenant des nanoparticules de phytoglycogène mono-dispersées et un autre polysaccharide hydratant, présentant une capacité synergiquement améliorée pour hydrater la peau. De préférence, le phytoglycogène est isolé d'une matière végétale telle que des grains de maïs sucré. Le polysaccharide hydratant peut être un glycosaminoglycane, un chitosan, un alginate ou un bêta-glucane. Dans des modes de réalisation préférés, le polysaccharide est l'acide hyaluronique. En outre, les compositions peuvent éventuellement comprendre divers supports, charges et agents actifs.
