Semisolid oral dispersions for improving the health and/or appearance of the oral cavity. The semisolid oral dispersions include hydrophilic active agent particles in hydrophobic phase. The hydrophilic active agent particles can include bleaching agents, antimicrobial agents, anticalculus agents, and/or combinations thereof. The hydrophilic active agent particle can have a solubility in water of at least about 20 parts, by weight of the particles, in about 100 parts, by weight, of water.

The present disclosure provides low-water oral care compositions comprising a whitening agent and a flavor system encapsulating one or more flavor ingredients, wherein the flavor system provides improved taste to the consumer, masking the negative taste attributes of the whitening or oxidizing agents, and is also believed to be able to improve the flavor stability over the life of the product, and methods of using the same.

Provided are: a glycerin dispersion in which the dispersibility and storage stability of a hydrophobized inorganic powder are improved; and a cosmetic containing the glycerin dispersion. A glycerin dispersion containing a hydrophobized inorganic powder, in which an inorganic powder is used as a base and hydrophobicity is imparted by coating the inorganic powder with an organic surface treatment agent, a polyglycerin-based nonionic surfactant, and glycerin is provided.

The invention relates to a process for producing a plurality of capsules, each comprising an external shell of crosslinked hydrogel surrounding a central core, according to which a hydrogel solution and a composition of interest, intended to form the central core, are concentrically co-extruded so as to form mixed drops, each comprising a layer of hydrogel solution surrounding a drop of liquid composition of interest, characterized in that the co-extrusion step is carried out above a crosslinking aerosol so that the mixed drops pass through said crosslinking aerosol, such that the layer of hydrogel solution at least partially crosslinks around the drop of liquid composition of interest on contact with said aerosol.
