Problems solved by technology

At present, some cosmetic milks have relatively simple functions, only have basic moisturizing functions, and cannot meet the diverse needs of people. Although some cosmetic milks have certain bactericidal and sunscreen functions, due to the complexity of the components, especially chemical sunscreens Adding it is very easy to cause allergic reactions to sensitive skin, so people urgently need an oil-controlling cosmetic milk that can improve oily skin quality, has sunscreen effect and antibacterial effect to solve the above problems

Abstract

The invention discloses oil controlling makeup cream for improving oily skin and a preparation method of the oil controlling makeup cream. The oil controlling makeup cream is prepared through the steps of firstly, preparing porous microspheres by using polylactic acid, hexamethylene oxide, low-hydrogen silicon oil and the like as raw materials, and loading nanometer silver granules on the porous microspheres through a reduction reaction of silver nitrate and sodium borohydride so as to obtain first modified microspheres; and grafting the porous microspheres with chitosan, enabling a chemical ultraviolet absorption agent to be adsorbed to the holes of the porous microspheres, and sealing the outlets of the holes of the porous microspheres with cyclodextrin to obtain solid second modified microspheres. Through synergistic reaction of the first modified microspheres and the second modified microspheres, the prepared makeup cream has excellent properties of controlling oil and improving skin, the bacteriostasis properties and the sunproof capacity are excellent, the lustrousness is good, the makeup cream is free from alcohol and essence, and is nonirritant to skin, people having sensitive skin can also use the makeup cream without worrying, and the makeup cream has good application prospects.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to an oil-control cosmetic emulsion for improving oily skin quality and a preparation method thereof. Background technique [0002] Ultraviolet light is a kind of light with a short wavelength but high energy, which has a strong destructive power on the skin. Exposing the skin to sunlight for a long time will not only lead to the deposition of melanin in the skin, darken the skin, and affect the appearance. It is also easy to accelerate the aging of skin cells, causing problems such as pigmentation, fine lines, redness and swelling, and causing irreversible damage to the skin; the current sunscreen methods in cosmetics are mainly divided into physical sunscreen and chemical sunscreen; although chemical sunscreen can be shielded to a certain extent Ultraviolet rays are harmful, but their properties are not stable, and the additives are more complicated, which is easy to cause damag...
