The present invention relates to the use of a mineral blend as cosmetic agent for a wet cosmetic composition, wherein the mineral blend comprises a first component being selected from natural ground calcium carbonate and/or precipitated calcium carbonate, and a second component being a surface-reacted calcium carbonate, as well as to a wet cosmetic composition comprising said mineral blend.

A solid cosmetic composition including 12 to 50% by weight of a non-volatile liquid fatty phase and 40 to 85% by weight of a pulverulent phase including spherical fillers that are surface-treated with a metallic soap. Also, a process for preparing such a solid cosmetic composition and a method for making up the skin or lips using such a solid cosmetic composition.

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.
