A free-flowing, substantially dry-to-the-touch, particulate composition comprises (A) finely particulate hydrophobic silicone-treated silica having a surface area of from 80 to 300 m2/g, (B) trimethylglycine, and (C) water, wherein the content of component (A) is greater than 2% and less than 8% by weight based on the total weight of components (A), (B) and (C) and wherein the content of component (B) is greater than 30% and less than 65% by weight based on the total weight of components (A), (B) and (C), said composition being in the form of particles of an aqueous solution of component (B) the surfaces of which particles are coated with a coating of component (A). The particulate composition is useful as a moisturising component in skin-care or cosmetic formulations.
