Title (EN) AEROSOL PRODUCT,METHOD FOR PREPARING AN AEROSOL PRODUCT AND DEVICE FOR IMPLEMENTING SUCH METHOD
(FR) PRODUIT AEROSOL, PROCEDE POUR LA PREPARATION D"UN PRODUIT AEROSOL ET DISPOSITIF POUR LA MISE EN OEUVRE DU PROCEDE
Abstract: front page image
(EN)The aerosol product, for exemple a cosmetic or pharmaceutical preparation, contains an active agent, a propelling agent and a solvent; with a view to protect the environment and the users the propelling agent is comprised exclusively of, helium, neon, argon, krypton or mixtures of these gases. A percentage of at least 80% by weight of argon with respect to the total weight of the propelling agent has proved to be particularly interesting. The method consist mainly in contacting the active agent and the solvent into an autoclave, introducing a compressed noble gas in a predetermined amount and collecting the mixture obtained. The mixing process may be repeated in other autoclaves with different noble gases. The device comprises mixtures (1, 2; 3) for storing the active agent and the solvent connected, as well as a pressure accumulator (a) for noble gases, to an autoclave (12) on which an outlet connexion (14) is fixed, above the ground. Several autoclaves (15, 18) may be provided as well as a filter having the shape of a candle (22, 10a), arranged after the last autoclave (18) and/or before the first autoclave (12).
(FR)Le produit aerosol, par exemple une preparation pharmaceutique ou cosmetique, renferme un agent actif, un agent propulseur et un solvant; l"agent propulseur est constitue exclusivement, en vue d"assurer la protection de l"environnement et des usagers, d"helium, de neon, d"argon, de krypton ou de melange de ces gaz. Un pourcentage en argon d"au moins 80% pds par rapport au poids total de l"agent propulseur s"est revele particulierement interessant. Le procede consiste principalement a mettre en contact l"agent actif et le solvant dans un autoclave, a introduire un gaz noble comprime en quantite determinee et a recueillir le melange obtenu. Le processus de melange peut etre repete dans d"autres autoclaves avec differents gaz nobles. Le dispositif comprend des melangeurs (1, 2, 3) pour le stockage de l"agent actif et du solvant relies, ainsi qu"un accumulateur de pression (12a) pour gaz nobles, a un autoclave (12) sur lequel est fixe un raccord de sortie (14), au-dessus du sol. On peut prevoir plusieurs autoclaves (15, 18) de meme qu"un filtre en forme de bougie (22, 10a), dispose apres le dernier autoclave (18) et/ou avant le premier autoclave (12).
