Description

Emollient oil containing water soluble active and its preparation method Technical Field The invention relates to the field of cosmetics, in particular to skin-moistening oil containing water-soluble active substances and a preparation method thereof. Background In recent years, the concept of 'nourishing skin with oil' rapidly lays down the skin care market by virtue of the unique skin care logic, and the proportion of pure oil system skin care products is steadily improved year by year. The product is favored, and has the core that the product can provide lasting and deep moisturizing effect for skin, is more easily compatible with skin sebum membrane in pure oil compared with the traditional water emulsion system, can rapidly relieve skin problems such as dryness and roughness, can enhance the absorption efficiency of skin to functional components, and meets the requirements of consumers on efficient skin care. However, most of the key functional components in the skin care field, such as nicotinamide with whitening effect, antioxidant VC ethyl ether, various water-soluble essences for moisturizing, and the like, are water-soluble substances. The natural characteristic of the obvious polarity difference between the oil and the water causes that the water-soluble active substances and the skin-care oil are difficult to be naturally fused to form a stable and uniform system, which becomes a core technical bottleneck for restricting the efficacy upgrading of the skin-care product of a pure oil system, so how to effectively and safely blend the water-soluble active substances in the skin-care oil becomes an important subject to be solved in the industry. In the current technical background, a solution commonly adopted in the industry is to combine water-soluble ingredients with emollient oils by means of the action of surfactants. Specifically, as disclosed in chinese patent application CN112957299a, a large amount of surfactant is added into the formulation to form reverse micelle by using the amphiphilic structure, and the water-soluble active substance is encapsulated therein, so as to achieve emulsification or solubilization of the water-soluble component, and finally prepare the related product containing the emollient oil. However, the technical scheme has certain defects that on one hand, the addition of a large amount of surfactant can destroy the self barrier function of skin, reduce skin resistance, easily cause allergic or stimulating reactions such as redness, stinging and the like, and are not friendly to sensitive muscle groups, on the other hand, products containing high proportion of surfactant are easy to generate foam when being shaken in the use process, destroy the smooth use feeling of the skin-moistening oil, and bring certain heavy feeling and greasy feeling to influence the use pleasure of consumers. In addition, the process has strict requirements on the type and the proportion of the surfactant, the research and development difficulty and the production cost of the product are increased intangibly, and the prepared product can also have stability problems such as layering, turbidity and the like in the long-term storage process. With the continuous improvement of safety, mildness and use experience requirements of consumers on skin care products, the existing technical scheme relying on a large amount of surfactants is difficult to meet market demands. The industry urgently needs a brand-new preparation method, which can break through the difficult problem of fusion of water-soluble active substances and skin-moistening oil, realize stable carrying of functional components, and avoid the irritation risk and the uncomfortable feeling caused by the surfactant. The ideal technical scheme has the characteristics of clear and transparent product appearance, good fluidity, strong stability and the like, simplifies the preparation process, reduces the production cost, further improves the efficacy and the use experience on the basis of keeping the mild safety attribute of the pure oil skin care product, and promotes the development of the oil skin care product to a more efficient, milder and better direction. Disclosure of Invention In order to solve the technical problems, the first aspect of the invention provides a skin-moistening oil containing water-soluble active substances, which comprises, by mass, 0.1-1 part of phase A, 3-15 parts of phase B and 80-100 parts of phase C, wherein the phase A is a water-soluble component, the phase B is a solvent, and the phase C is skin-moistening oil. As one practical example, the water-soluble component includes one or more of deionized water, VC ethyl ether, ascorbyl glucoside, sodium ascorbyl phosphate, magnesium ascorbyl phosphate, glutathione, α -arbutin, tranexamic acid, nicotinamide, panthenol, ceramide, acetylglucosamine, inositol, allantoin, or vitamin B6. Further, the phase A comprises one or more of deionized water, VC ethyl ether and ni
