Abstract: Cosmetic compositions comprising calcium citrate and at least one N-acylated aminoalcohol according to formula (I). Provided is a method of treating aged skin, comprising topically applying to the aged skin a composition comprising a compound of Formula (I) in an amount effective to provide an anti-ageing effect. The compound of Formula (I) is used to prevent skin and/or to help to maintain or improve moisture retention and/or to fight against the signs of skin ageing. The N-acylated aminoalcohol of formula (I) acts as a ceramidase inhibitor. The combination of at least one compound of formula (I) and calcium citrate stimulates keratinocyte differentiation.

Abstract: A process for making hydrophobicized powders of micro- and/or nanocapsules involving the steps of: (a) providing an aqueous polymer solution containing at least one active ingredient and at least one hydrophilic polymer; (b) providing an oil component heated to a temperature above a gel point of the aqueous polymer solution; (c) dispersing (a) in (b) in the presence of a water-in-oil emulsifier to form a dispersion; (d) cooling the dispersion to a temperature below the gel point of the aqueous polymer solution to form micro- and/or nanocapsules containing the active ingredient encapsulated therein; (e) harvesting the micro- and/or nanocapsules from the dispersion; and (f) contacting the micro- and/or nanocapsules with an oil-absorbing auxiliary ingredient.

Abstract: Methods for treating the skin and/or hair comprising: (a) providing a composition comprising a sugar ester; and (b) contacting a substrate selected from the group consisting of skin and hair with the composition are described.

Abstract: A matrix for preparing microparticles or nanoparticles, method for making the particles and resulting particles, more particularly a matrix for forming microparticles or nanoparticles by hot dispersion in a non-miscible gas or liquid medium, characterised in that it consists of at least a solid hydrophobic element at room temperature and of at least a liquid element, hydrophobic and/or lipophilic, hot mixed by solubilizing the solid element(s) in the liquid element(s), the matrix having a melting point ranging between 25° C. and 85° C.
