Problems solved by technology

At present, most facial cleansers have the effect of exfoliating. Some products mostly add a certain concentration of fruit acid or BHA to soften the cuticle and help exfoliate the old waste cuticle. However, it is irritating to a certain extent, and sensitive skin needs to be used with caution.

Abstract

The invention aims to provide a biomass microsphere for beauty treatment and keratin removal and a preparation method thereof. The biomass microsphere is prepared by the following steps: compounding starch with iron oxide, ferriferrous oxide, or other magnetic particles and then carrying out self-assembly among the processed starch, titanium dioxide, and active carbon. The magnetic starch maintains the advantages of starch and also has the advantages of good biocompatibility, excellent magnetic responsibility, and good loading and sustained release function. The biomass microsphere is usually added into a common facial cleanser so as to remove the keratin quickly. The magnetized starch and titanium dioxide only rub the cuticle of face, thus the friction will not hurt the skin, and the biomass microsphere has an adsorption effect and can absorb fine keratin so as to prevent the contact between the keratin and skin during the washing process.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a biomass microsphere used for cosmetic exfoliation and a preparation method thereof. Background technique [0002] The stratum corneum is the outermost layer of the skin and has the function of protecting the skin and locking in moisture. The keratin that should be naturally metabolized will become unable to metabolize normally due to skin aging, incomplete cleansing, sun exposure, oil production, changes in work and rest, and weather changes. Moderate exfoliation is very important. In addition to feeling the smooth touch of the skin, it can also make the ingredients of skin care products easily absorbed by the skin, thereby maintaining the metabolism of the skin, and many skin problems can be more or less improved. [0003] The skin originally has the ability to remove old dead skin cells, but modern people are affected by factors such as exposure to external env...
