Description

High-permeability moisturizing composition, skin moisturizer and preparation method
Technical Field
The invention relates to a daily-use fine chemical product, in particular to a high-permeability moisturizing composition, a skin moisturizer and a preparation method.
Background
The skin is the largest organ of the human body and plays an important role in preventing water loss of the human body, external pollution, irritation and the like. With the internal and external reasons such as age, working pressure, living habits, ultraviolet irradiation, environmental pollution and the like, the skin is more severely deficient in water.
Skin care products on the market at present mainly focus on products such as moisturizing water, lotion, cream and the like. These products are mostly made by adding emulsifiers, thickeners and conditioning ingredients to a moisturizing solvent based on water and alcohol. The moisturizing component mainly comprises water and polyhydric alcohol, while the water is volatile, and the polyhydric alcohol is relatively difficult to volatilize but is easy to generate skin irritation.
Many moisturizing components mainly comprising water and polyhydric alcohol have low permeability, stay on the skin surface, and are prevented from further penetration after the skin stratum corneum is soaked and foamed after contacting the skin. There are also products that aim to increase the residence time of moisturizing ingredients, mainly by adding ingredients such as carbomers that increase viscosity to form a high viscosity serum, but this also reduces the freshness of the skin care product.
Sensitive skin has a certain relationship with the structure of the skin itself and the immediate state of the sensory nerves in addition to the influence of contact and action of specific substances and specific irradiation, and also needs to have better adaptability to the sensitive skin for high-permeability moisturizing ingredients.
With the improvement of living standard, the product is environment-friendly, has low stimulation, and can effectively penetrate skin and keep moisture, so that the product is more easily accepted by the market.
