Problems solved by technology

However, both technologies contain emulsifiers or surfactants, which are likely to cause some irritation to sensitive skin
[0004] In the technical field of cosmetics, the oil-water two-phase dispersion system that does not contain surfactants in the existing public documents has a relatively single choice of oil, and many types of oil cannot be selected, so many oil-soluble functional ingredients cannot be added, and The content of oil is less, and the particle size of oil distributed in the water phase is larger, so the stability of the material body is poor

Abstract

The invention provides a two-phase skin care composition, which comprises the following components: 0.05-0.5% of tocopherol, 1.5-3% of white pond flower seed oil, 1-3% of isononyl isononanoate, caprylic / capric glycerin Triglyceride 1.5-3.5%, Coco-Caprylate / Caprate 4-10%, Humectant 3-8%, Chelating Agent 0.03-0.1%, Preservative 0.8-2.0%, Thickener 0.22-0.85 %, sodium hyaluronate 0.05-0.2%. The two-phase skin care composition is composed of a water phase and an oil phase. By selecting a suitable thickener and a special three-step preparation process, the oil phase is uniformly dispersed with a smaller particle size without adding an emulsifier. in the water phase. Moreover, the present invention selects more types of oils, which can have better compatibility with various active functional ingredients; and the present invention has high oil content, good material stability and better skin feel. Since the invention does not contain any emulsifier or surfactant, the irritation to the skin is reduced and the skin feels mild.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a two-phase skin care composition and a preparation method thereof. Background technique [0002] With the popularization of the use of cosmetics, more and more consumers are increasingly pursuing the efficacy of cosmetics. Cosmetics of all-water system have a simpler skin feel, and the skin is lipophilic. The pure water system has less effect on the skin and emollient and promotes the penetration of functional ingredients than the system containing oil; and some active ingredients are oil-soluble, The pure water system limits the selection of active ingredients, so that oil-soluble functional ingredients cannot be selected. Most products on the market combine oil phase and water phase in cosmetics through emulsification, but cosmetics are products that are in direct contact with the skin, and the surfactants in the products have a certain stimulating effect on sen...
