CA 2367875
The invention relates to the use of nanoscalar water-soluble .beta.-(1,3) glucans, which are essentially free from (1,6) links and have particle diameters ranging from 10 to 300 nm for producing cosmetic and/or pharmaceutical preparations. When applied topically, the especially fine dispersion of the particles compared to prior art glucans facilitates their rapid penetration of both the stratum corneum of the skin and the keratin fibres of the hair.
Cette invention concerne l'utilisation de .beta.-(1,3)-glucanes nanométriques hydrosolubles, quasiment exempts de liaisons (1, 6) et présentant des diamètres de particules compris entre 10 et 300 nm, pour produire des préparations cosmétiques et/ou pharmaceutiques. Par rapport aux glucanes existants, la finesse toute particulière des particules de ces glucanes leur permet de pénétrer rapidement dans la couche cornée et dans les fibrilles de kératine des cheveux, en application topique.
