With the temperature rise of the color make-up market, the potential of the make-up removal product is also released rapidly. It is expected that with the increasing health consciousness of residents and the increasing living standard, more and more female consumers will use makeup removing products, and the importance of the makeup removing products in cosmetics is increasingly prominent, and the market demand of the makeup removing products is also increasing. According to the different makeup removing principles, the makeup removing product can be further divided into makeup removing water/liquid, makeup removing oil, makeup removing cream, makeup removing emulsion, makeup removing gel, makeup removing wet tissues and the like. The research report of the authorities shows that the market share of the online makeup remover is being transferred to the types of makeup remover, makeup remover wet tissues and the like. The cleansing cream is popular among all brands as cleansing cream which is convenient to carry, combines washing and cleansing and can remove concentrated makeup rapidly. In the face of new consumer complaints and new consumption scenes, on the basis of urban high-rhythm life pressure background, new products of the makeup removal cream need to be continuously optimized and innovated in terms of factors such as using freshness, makeup removal capability, emulsification cleaning effect or external packing design, for example, the product is declared to be clean without intentional emulsification by the primary explosion type single-product bilberry moringa seed makeup removal cream; the cream can be emulsified for 3 seconds when in use, can be cleaned for one time and achieves the subtle balance of cleaning force and temperature; for example, the Mikania micrantha grease cleansing cream is declared to be body-feel cleansing cream, and small molecular grease penetrates into pores to wrap cleansing residues, so that the cleansing residues are emulsified for one second and secondary cleaning is not needed.

Make-up removal products can be broadly divided into make-up removal oils/creams and make-up removal ointments;

The make-up remover has relatively few comparative documents, and reference is made to the following documents:

d8: CN201510266286 discloses a mild no-clean cleansing cream, which is characterized by comprising the following components in percentage by weight: 2 to 10 percent of polyethylene, 2 to 20 percent of cetyl alcohol ethyl caproate, 2 to 20 percent of PEG-10 isostearate, 2 to 20 percent of PEG-20 glycerol triisostearate, 0.2 to 1 percent of tocopheryl acetate, 2 to 10 percent of phenyl trimethicone, 0.2 to 3.0 percent of dextrin palmitate and the balance of caprylic acid/capric acid triglyceride.

The nonionic emulsifier is used, and is specifically PEG-20 glycerol triisostearate and PEG-10 isostearate. Both HLB values are about 11, the dissolution strength of polar synthetic oil is high, but the dissolution performance of the p-phenyl siloxane and the cyclic siloxane is poor, so that the residual oil film feeling after makeup removal is enhanced, and the freshness after makeup removal is reduced.

D9: 103191027a discloses a solid make-up remover with warm feel in use, wherein more than 15% of polyol is added in the formula to enable the make-up remover to generate warm feel when contacting skin through hydration, and a polyol thickener of polyglycerol-10 behenate/eicosanedioate is added to thicken the polyol, so that the polyol with high addition amount can be mixed with other oil components to be solidified and stabilized.
