A powdery composition, comprising: a) core-shell particles having a shell of hydrophobic or hydrophobized particles; and b) a carrier powder comprising a carrier and at least one of an at least partially water soluble liquid and a water reactive substrate reversibly bound to the carrier by at least one of the capillary action, absorption and adsorption is provided. The core-shell particles have a core, comprising: water; and 0 to 10 wt. % of a total core weight of a dissolved or emulsified material. The carrier comprises at least one material selected from the group consisting of silica, a silica-metal mixed oxide, phyllosilicate, starch, hollow glass spheres, nylon, sugar, cyclodextrines and polysaccharides, and a weight ratio of the carrier powder to the core-shell particles is from 1/1 to 1/9. A creamy composition is manufactured from the powdery composition-by an energy input in form of pressure, shear, temperature, vibration and/or solvent addition, the energy input being sufficient to release the liquid water or the liquid aqueous phase from the core-shell material and subsequently dissolving or flushing the produce or products from the carrier. |
