The number of gel products on the market is not sufficient at present, and most of the gel products are obtained by adding polymers, and only a few gel products are not added polymers.

Conventional gel product formulations without added polymer, for example: a polyol-in-oil gel composition having mild cleansing action, the composition comprising, based on the total weight of the composition: 20-70 wt% of a polyol; 0.4-10% by weight of an emulsifier; 20-80 wt% of an oil or fat; wherein the sum of the components in the composition is 100 wt%, and the emulsifier is selected from sucrose laurate, hydrogenated lecithin, cetostearyl glycoside, inulin lauryl carbamate, or combinations thereof. For another example: a vegetable oil nano emulsion prepared by a D-phase emulsification method is characterized by comprising the following raw materials in percentage by weight: 5-30% of vegetable oil; 1-8% of an emulsifier; 5-20% of polyhydric alcohol; the balance of water; the emulsifier is a compound mixture consisting of any one or more than two of fatty alcohol-polyoxyethylene ether, ethoxylated hydrogenated castor oil, glyceryl stearate, fatty acid polyoxyethylene ester, sorbitan fatty acid ester and polyoxyethylene sorbitan fatty acid ester. The traditional gel product formula without the added polymer has the effects of cleaning skin, moistening skin and the like.

However, when the conventional gel product formula is used for cleaning skin, especially for removing makeup, the makeup removing effect for different makeup product types is different. Therefore, consumers often need to purchase corresponding makeup removing products for different makeup product categories.
