Provided is a cosmetic composition which includes at least one silicone resin and at least one emulsifier.

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 production of a cosmetic cake (8) is described, consisting of a base supporting and anchoring layer (6) and an overlapping cosmetic product layer (4), wherein said base layer (6) is formed using a dried and solidified aqueous mixture of only natural non-synthetic ingredients.

There is described the manufacturing of a support (6) for cosmetic products, which consists of a dry and solidified set of a mixture consisting of non-synthetic ingredients of natural origin only. The support can be manufactured so as to form a base for supporting and anchoring a cosmetic product inside a container (9) or a biodegradable container in the shape of a rigid and self-supporting cosmetic wafer for anhydrous or gel cosmetic products.

Provided is an oil powder foundation which utilizes advantageous features of a powder foundation and an oil foundation and has solved problems that these foundations have, and which gives natural finish having high hiding power. The oil powder foundation may include (a) spherical particles, (b) titanium dioxide, (c) a film-forming agent, (d) a volatile oil agent, and (e) a surfactant. Using a urethane powder, acrylic powder, nylon powder, silicone powder, cellulose powder, silica powder, or calcium carbonate powder having an average particle diameter of 5 to 20 μm as the component (a), the oil powder foundation is prepared so that the total of the component (a) and the component (b) is contained in an amount of 35 to 55% by mass and the mass ratio of the component (a) and the component (b) is 1 to 1.5:1.5 to 1.
