Makeup is a polite gesture to others in etiquette, and makeup is also a method of facial modification needed in modern society. All of this ultimately involves makeup removal. If makeup is not removed after application, the skin will be like wearing a "mask" to sleep, which will cause the facial skin to be unable to breathe normally for a long time, and thus will cause negative skin problems such as acne or accelerated aging. Therefore, after makeup, a makeup removal product is needed to remove dirt, excess oil, residual makeup, dust, and the like on the face, and to help the skin maintain a clean and fresh state to avoid causing large pores and blockage.

[0003] Currently, there are many types of makeup removal products on the market, such as makeup removal cream, makeup removal milk, makeup removal jelly, makeup removal oil, and makeup removal water. For example, CN 111920711 A discloses a gel composition comprising polyol, emulsifier, and oil, the emulsifier being selected from at least one of sodium di(lauroamidoglutamate) lysine, PEG-20 glyceryl triisostearate, and sodium iturin.
