A manufacturing method for porous resin microparticles comprising steps of: heating a polyester thermoplastic resin having biodegradability to a temperature of 80° C. or higher and 200° C. or lower in a glycol ether solvent to obtain a solution, and cooling the solution to precipitate the polyester thermoplastic resin as porous resin microparticles.

A cosmetic having excellent properties in transparency, spreadability, smoothness, skin compatibility and safety is prepared using a synthetic talc that is flake-like particles containing 2:1-type laminar crystals of silicate which have a basic structure of an octahedron sheet sandwiched between two tetrahedron sheets. The flake-like particle has a mean volume particle diameter of 0.5 to 100 μm, and 0.3° or less of half width at half maximum of peak present at 2θ equal to 9.4°±1° when measured by unoriented powder X-ray diffractometry (XRD) using CuKα rays, and the cosmetic is substantially free of Mg.sub.3Si.sub.2O.sub.5(OH).sub.4.

An apparatus and method for depositing a particulate containing composition onto mammalian skin such that when the particles contact the mammalian skin they have a momentum defined by ρvr, which is within the range of about 0.1 kg/ms≦ρvr≦about 12.0 kg/ms. The particles can be in the range of from about 10 nanometers to about 10 micrometers, in size. And the particles may be selected from the group consisting of titanium dioxide, zinc oxide, iron oxide, polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, polyvinyl chloride, glass, silica and mixtures thereof. The particles are imbedded below the first layer of dead skin cells in the stratum corneum but they do not pass all the way through the stratum corneum into the living cells of the epidermis or dermis layers of the skin.

The disclosure discloses a liquid foundation using starch as a filler and a preparation method thereof, belonging to the technical fields of deep processing of starch and preparation of cosmetics. In the disclosure, starch is modified by an OSA reagent and then homogenized and micronized to obtain a starch filler; powder materials and the water phase in the formula of the liquid foundation are sequentially added to the oil phase at a certain temperature; the mixture is sheared at low speed, homogenized, and cooled to room temperature; and the starch filler is added to prepare the liquid foundation using starch as a filler, wherein the formula includes 10-20 parts of oil phase, 65-75 parts of water phase, 5-10 parts of toner, and 5-15 parts of starch filler. The starch filler in the disclosure is hypoallergenic, environmental and safe, and the liquid foundation containing the starch filler is refreshing and not easy to clog pores, solves the problems of traditional fillers which are thick and greasy, unbreathable, easy to aggravate facial acne, and the like, and is in line with the current propensity to consume of consumers for green and safe beauty products.
