Description

Double-layer cleansing lotion and preparation method thereof

Technical Field

The invention discloses a makeup remover and a preparation method thereof, in particular to a double-layer makeup remover, and belongs to the technical field of cosmetics.

Background

With the development of the color makeup market, makeup removal concepts are more and more concerned by beauty-lovers, and in addition, air pollution makes products such as isolation, BB cream, sun protection and the like become necessary matters for people, the color makeup products are frequently used, and if the cleansing is not proper and the makeup removal is not thorough, pores are easily blocked, so a series of skin problems are caused, so the makeup removal products become an indispensable important component in skin care.

The makeup removing products on the market mainly comprise makeup removing oil and makeup removing water, and the appearance of the makeup removing products is uniform liquid. The makeup remover oil is grease added with an emulsifier, can be easily fused with color makeup and oil stains on the face according to the principle of similarity and intermiscibility, and takes away dirt on the face in a water emulsification mode during washing to play a role in makeup removal. The makeup remover is also called washing lotion, the water content is about 90 percent, the main function is to remove the makeup from the face and has certain moisturizing function. The cleansing oil has strong cleaning capability on oil-soluble dirt, but the skin feels thick due to high grease content, so pores can be blocked again; the cleansing water has higher moisture content, light skin feel and small irritation, but has poor cleaning capability on oil-soluble dirt. Aiming at the problems, the makeup remover has oil-water layered makeup remover in recent years, integrates the advantages of the makeup remover and the makeup remover, and solves the defects of heavy skin feel of a single product or incomplete cleaning of oil-soluble makeup.

At present, double-layer makeup removing products in the market mainly achieve the purpose of layering by using the difference between oil-water incompatibility and specific gravity, and generally have common appearance and cannot attract consumers because the upper layer is a transparent oil phase and the lower layer is a transparent water phase. In order to meet the requirements of consumers on product diversification and solve the problems of product appearance and dosage form singleness, a novel double-layer makeup removing product needs to be developed.
