摘要：
The invention concerns particles consisting essentially of fibers of an organogelling substance in the form of xerogel (dry gel), the fibers being essentially oriented in a common direction and randomly aligned around the longest fiber. The organogelling substance is preferably 1,3: 2,4-di-O-benzylidene-D-sorbitol. Said particles, which are in the form of spindles, have interesting optical properties they have a total light transmittance higher than 0.80, with a diffuse transmittance higher than the specular transmittance. The invention also concerns a method for preparing said particles by solvent evaporation process, by solvent diffusion/evaporation process or by shearing process. The invention finally concerns active particles consisting of said particles whereon is immobilized a dermocosmetically active principle, a dermocosmetic composition comprising said particles or said active particles and a cosmetic treatment method which consists in applying on the skin said dermocosmetic composition.
