Abstract

The invention discloses double-layer emulsion comprising the following components by weight: 5 to 30% of an oil phase, 0.1 to 2.5% of an emulsifier, 0.3 to 10% of a moisturizer and 0.01 to 0.2% of a stabilizer; the emulsifier comprises inulin lauryl carbamate; the inulin lauryl carbamate in the double-layer emulsion has a weight percentage of 0.1 to 1%. The double-layer emulsion can be shaken wellbefore use to form a single-phase emulsion, a smooth and moisturizing grease protection film can be formed on the face after application, skin water loss can be reduced, and skin hydration degree canbe increased. The time required for the product to be returned to the bilayer state after being shaken and mixed after being left standing is short, the double-layer emulsion has the effects same asthat of the single phase emulsion, and meanwhile a suspension stabilizer is not specially needed, so that the spreadability of the emulsion is better, and the skin feeling is more refreshing.

Description

technical field [0001] The invention relates to an emulsion, in particular to a double-layer emulsion. Background technique [0002] With the improvement of people's living standards and the enhancement of skin care awareness, both women and men pay more and more attention to skin care issues. Among them, cleansing the skin is the basis of skin care, and moisturizing care after cleaning is also essential. Therefore, lotion products have become an indispensable household daily necessities in daily life. [0003] When human skin is in a healthy and normal state, a very thin layer of sebum is secreted on the surface of the skin to keep the skin shiny and lubricated. After cleansing the skin, the protection of the skin's sebum layer becomes weak. If no moisturizing measures are taken, the skin will become dry due to the increased rate of transepidermal water loss, and even itching and dandruff will fall off. [0004] Some developers try to make a stable double-layer emulsion s...
