Description

Facial cleanser for cleaning skin and preventing skin from depositing solid particles and preparation method thereof

Technical Field

The invention belongs to a facial cleanser, and particularly relates to a facial cleanser for cleaning skin solid particles and preventing skin from depositing the solid particles and a preparation method thereof.

Background

The facial cleanser is a facial cleaning product for cleaning skin, has good cleaning ability and a certain nursing function. With the improvement of living standard of people, facial cleanser is gradually accepted by consumers as a facial cleaning product. Aiming at facial cleanser products, products sold on the market at present are mainly classified into deep decontamination type, mild type, moisturizing type and the like, wherein the deep decontamination type facial cleanser mostly takes fatty acid soap as a main active substance, and the product can thoroughly remove facial oil stains, but the product is usually dry and tight in skin after washing due to strong alkalinity of the product and is mostly suitable for oily skin; the mild facial cleanser mostly takes amino acid type surfactant as a main active substance, has poor detergency, is mild to skin, has small irritation, and is suitable for neutral and dry skin; for moisturizing facial cleansers, some moisturizing components are mostly added into the two types of facial cleansers, and the whole formula system is not changed greatly.

Although the awareness of environmental protection of people is enhanced at present, dust pollution happens occasionally, and if dust suspended particles are not cleaned, skin conditions such as large pores and excessive secretion of grease can be caused, so that fine lines, wrinkles, sagging and dryness of the skin occur, and problems such as acne and acne are caused.
