[0038] Glycerin: also known as propylene glycol, is a colorless, transparent, viscous liquid that has a good moisture absorption and moisturizing effect and has a significant moisturizing effect on human skin.

[0039] Propylene glycol: It is a colorless, transparent, viscous liquid with a slightly special smell. It has mild and refreshing moisturizing properties, low stickiness, excellent moisturizing effect and use effect, good safety, and is non-irritating and non-sensitizing.

[0040] Sodium ascorbyl phosphate, vitamin E: Vitamins are essential organic substances for the human body. Adding vitamins and their derivatives has the effects of whitening the skin and anti-aging. Sodium ascorbyl phosphate is a vitamin C derivative with stable physical and chemical properties. It is processed with vitamin C as raw material. After entering the human body, it is rapidly enzymatically hydrolyzed by phosphatase to release vitamin C, exerting its unique physiological and biochemical functions. Vitamin C has strong antioxidant properties and can promote collagen synthesis and inhibit collagen decomposition; vitamin E is a natural antioxidant that can promote metabolism and improve skin elasticity. Vitamin C and vitamin E have the effect of synergistically scavenging free radicals.

[0041] Aloe extract: It is a colorless, transparent, slightly viscous liquid with strong moisturizing properties. Aloe's anthraquinone compounds have the properties of astringent, softening, moisturizing, anti-inflammatory, and bleaching the skin. They also have the effects of relieving hardening, keratinization, and improving scars. They can not only prevent small wrinkles, eye bags, and sagging skin, but also keep the skin moist and delicate. At the same time, they can also treat skin inflammation, and have a good effect on acne, freckles, acne, burns, knife wounds, insect bites, etc. It is also effective for hair, keeping hair moist and smooth and preventing hair loss.

[0042] Hydroxyethyl cellulose: It is a white or light yellow, odorless, non-toxic fibrous or powdered solid, generally used as a thickener, protective agent, adhesive, stabilizer and additive for the preparation of emulsions, jellies, ointments, lotions, eye cleansers, suppositories and tablets.

[0043] Phenoxyethanol: It is a colorless, slightly viscous liquid with an aromatic odor. It is slightly soluble in water and easily soluble in ethanol and sodium hydroxide. Phenoxyethanol has antibacterial effects and low toxicity. It is chemically inactive to copper and lead, so it usually acts as a preservative in cosmetics, skin care products, vaccines and medicines.

[0044] Lavender oil: It is a colorless to light yellow liquid. Its main components are linalyl acetate, lavandinol, linalool, terpineol, geraniol, nerol, camphor, borneol, terpineol acetate, lavandin acetate, nonanal, pinene, myrcene, ocimene, etc. It has a sweet floral scent. Medical research shows that after the aromatic smell is absorbed by the human body, it acts on the whole body through breathing. The volatile aroma can strongly stimulate the human respiratory center, thereby promoting the body to inhale oxygen and expel carbon dioxide, thus making the body energetic, relaxed and happy, promoting blood circulation, and enhancing immunity and functional vitality.

[0045] Menthol: It is a terpene organic compound extracted from the leaves and stems of mint. It is a white crystal and is the main component of mint and peppermint essential oils. Menthol can be used as a flavoring agent in toothpaste, perfume, beverages and candies. It is used as a stimulant in medicine and cosmetics, acting on the skin or mucous membranes, with a cooling and antipruritic effect. It can be taken internally as a wind-repellent for headaches and inflammation of the nose, pharynx and throat.

[0046] Sodium polyacrylate: It is a new functional polymer material and an important chemical product. The solid product is white or light yellow block or powder. It is often used as a water treatment agent, brine refining and latex thickening. It can also be used as a thickener and emulsifier for food and cosmetics.

[0047] Bisabolol: Bisabolol is divided into α-bisabolol and β-bisabolol. β-bisabolol is generally derived from corn, cotton, and camphor oil, and is generally used as a flavoring agent in the food field. The present invention is preferably α-bisabolol, which is a natural monocyclic sesquiterpene alcohol and the main component extracted from chamomile. It has anti-inflammatory, antibacterial, soothing and other effects, and has a certain inhibitory effect on skin inflammation. It can be used in skin protection and skin care cosmetics as an active ingredient to protect and care for allergic skin.

[0048] Generally speaking, substances that can keep the moisture in the stratum corneum of the skin are called moisturizers. According to the mechanism by which moisturizers exert their moisturizing effect, moisturizers can be divided into two categories: the first category is hydrophilic substances, such as glycerin, hyaluronic acid, etc., which mainly achieve moisturizing by enhancing the water absorption and water binding ability of the stratum corneum of the skin; the second category is oily substances, such as octadecyl alcohol, lanolin, vaseline, etc., which can form a continuous oil film on the surface to reduce the volatilization of moisture in the skin and prevent or reduce the loss of moisture in the stratum corneum. The skin composition in the present invention belongs to the first category and can be used in corresponding types of cosmetics.

[0049] Compared with the prior art, the present invention has the following characteristics:

[0050] 1) Through a large number of screening tests, including screening of component types and dosages, and optimizing the preparation method, the best formula with moderate viscosity and mild skin feel and its corresponding preparation process were finally screened out, thereby obtaining a skin composition with good moisturizing and soothing effects, and the skin composition is non-irritating, safe and reliable, and has significant effects.

[0051] 2) The addition of menthol not only makes the skin composition have a cool and refreshing feeling, but also promotes the absorption of functional components (such as sodium ascorbyl phosphate, vitamin E, aloe extract, etc.).

[0052] 3) The addition of hydroxyethyl cellulose and sodium polyacrylate increases the viscosity of the skin composition, improves the adhesion, and prevents the skin composition from drying up quickly after being applied to the skin. DETAILED DESCRIPTION
