KimaCell® EC N10 ethyl cellulose is a kind of water-insoluble cellulose ether and can be used as a transparent film-forming agent and oil-phase thickener. Applying it to oil-in-water lip gloss can bring For a fresh, hydrated skin feel and long-lasting radiance. It can thicken the oil phase and absorb pigment particles to firmly adhere to the lip skin. The incompatible silicone oil phase in the formula precipitates to the upper layer to form an anti-transfer oil film. Oil-based lip glazes have better resistance to color transfer.

KimaCell® EC N10 ethyl cellulose is used in The lip makeup market, and the growth rate of lip gloss is the fastest. Lip gloss dosage forms include traditional pure oil wax type and emulsified type, and emulsified type includes oil-in-water type and water-in-oil type. Among them is a new type of oil-in-water lip gloss. Through reasonable formula technology and selection of raw materials, it can get rid of the thick and sticky feeling of traditional lip gloss, and has a moist and refreshing skin feeling. Better moisturization and durability. The formula of this new type of oil-in-water lip gloss has superior performance, but due to the oil phase, the incompatible silicone oil phase and the pigment phase are mixed and suspended in the water phase, so the formula is unstable, and the oil-soluble ethyl cellulose The oil phase dispersed into the water-based lip gloss by emulsification to achieve the stability of the formula is the key reason.
The formula of the new oil-in-water lip glaze is relatively difficult to stabilize, and the addition of ethyl cellulose can increase the stability of the formula. The possible mechanism is that ethyl cellulose can thicken the oil phase. In addition, due to the special structure and solubility of ethyl cellulose, it is an ethyl ether of cellulose, which is insoluble in the water phase and only partially soluble Oils, such as octyldodecanol in the formula, are not soluble in other parts of the formula. This special structure and solubility make them mainly distributed at the oil phase and the water-oil interface, and the resulting position The anti-repulsion effect makes the emulsified formula droplets more stable and difficult to separate.
