The present disclosure relates to delivery systems. More particularly, the present disclosure relates to a process for releasing an active ingredient including a step of contacting a powdered composition with a medium having a pH≤7. The powdered composition includes granules made of a water soluble polymer matrix, an oil phase dispersed in said matrix and carbonate particles. Consumer products such as an antiperspirant or deodorant composition or a powder soft drink beverage composition including the powdered composition are also object of the present disclosure.

The invention relates to an extract of flowers, preferably calyxes, from kapok trees, in particular Bombax costatum, to a process for preparing same and to the extract obtainable by said process. The invention also relates to a composition comprising such an extract, the composition being advantageously a cosmetic, pharmaceutical or dermatological composition. The invention also relates to such a composition or such an extract for use in preventing or treating disorders or diseases of the skin, the mucous membranes or keratinous appendages and for use in preventing or treating vascular disorders. The invention finally relates to a cosmetic care process for the skin, the keratinous appendages or the mucous membranes, with a view to improving the condition thereof or the appearance thereof, which process consists in administering such a composition or such an extract.

The present disclosure relates to compositions for altering the tone or color of the hair, the compositions comprising at least one amino acid, at least one carboxylic acid, monoethanolamine, an oxidation base chosen from toluene-2,5-diamine, acid salts thereof, or solvates thereof, and a coupler system comprising one or more couplers chosen from 2,4-diaminophenoxyethanol, meta-aminophenol, and 4-amino-2-hydroxy toluene, derivatives thereof, addition salts thereof, solvates thereof, solvates of salts thereof, or mixtures thereof. The disclosure also relates to methods of using the compositions and kits comprising the compositions.
