With the development of cosmetic technology, cosmetics play an increasingly important role in people's daily life. However, after the face is made up, if the face is not cleaned completely, the residual cosmetics can cause the pore blockage of the face skin, so that the oil and water secretion of the skin is disordered, and the puzzling skin problems such as acne, comedo and blackhead are caused. Therefore, the makeup removing link of the skin is very important.

The existing makeup removing cosmetics mainly comprise makeup removing oil and makeup removing water. The cleansing oil mainly comprises grease and an emulsifier, and can remove some residual makeup oil stains on the face according to the principle that the grease is compatible with each other, thereby achieving the effect of dissolving stains. The makeup removing oil is required to be used for massaging and dissolving oil stains on the skin under the condition of drying hands and faces, water is required to be used for emulsification after massage, stains are washed off, and the makeup removing oil has strong cleaning power on oil-soluble stains. Because the cleansing oil has high oil content, heavy skin feel and high irritation, the cleansing oil is not suitable for oily skin, acne skin and sensitive skin, and is easy to remain on the skin, pores are easy to block if the cleansing oil is not cleaned for the second time, and the secondary cleaning is easy to excessively remove the oil on the skin to damage the barrier capability of the skin. The makeup remover can dissolve dirt, residual cosmetics and the like on the skin through water-insoluble components contained in the makeup remover, so that the effect of removing the makeup is achieved. The makeup remover mainly comprises water, has light skin feel and small irritation, can supplement water for the skin while removing the makeup, and is suitable for various skin types, particularly sensitive skin and oily skin; but the oil content is less, so that the oil-soluble makeup oil stain cleaning force is insufficient.
