Beschreibung
Zusammenfassung:	A method of producing balls (filled capsules) for cosmetic products comprises forming capsules by adding one or more calcium salts to a solution of alginate before coextruding it with an active principle in a coaxial flow of air, and gelling in an oil bath containing acid(s). The extruded solution is introduced into the bath drop by drop using a peristaltic pump. The capsules are then recovered from the oil bath on an inclined rolling belt ,with the separated oil being reintroduced into the oil bath. The process is continuous. Independent claims are included for: (1) Balls produced by the method and containing caffeine as the active ingredient; and (2) A cosmetic product comprising the balls. L'invention concerne un procédé de fabrication de billes d'alginate renfermant au moins un actif cosmétique, les billes d'alginate ainsi obtenues et les produits cosmétiques susceptibles d'incorporer ces billes d'alginate.Le procédé de fabrication de billes destinées à être incorporées à un produit cosmétique est du type comprenant une étape de formation desdites billes par extrusion d'une solution d'alginate et d'au moins un actif cosmétique avec flux coaxial d'air. Selon l'invention, le procédé comprend une étape d'adjonction d'au moins un sel de calcium à ladite solution et une étape de gélification de ladite solution extrudée à l'aide d'un bain huileux (51) contenant au moins un acide.
