Description
Technical Field
The invention relates to the field of skin care products, and particularly relates to a sunscreen composition and application thereof.
Background
Sunlight is an indispensable part of life and includes X-rays, ultraviolet rays, visible rays, infrared rays, and the like. Most of them are blocked by the atmosphere, and if the ecological environment on which people live is further damaged, especially the ozone content of the ozone layer is further reduced, the intensity of ultraviolet rays entering the earth will be increased. When a human is exposed to ultraviolet radiation for a long time and in a large dose, the human can cause great damage to the skin and even the whole body. Because the skin is the outermost organ and tissue of the body, the damage caused by ultraviolet rays is more prominent and obvious.
Ultraviolet rays are the part of the solar spectrum with wavelengths of 200-400nm, accounting for about 6.1% of sunlight, and are divided into 3 segments according to their wavelengths: short-band ultraviolet (UVC, 200-280 nm), medium-band ultraviolet (UVB, 280-320 nm), and long-band ultraviolet (UVA, 320-400 nm). Wherein, the UVC area is called as a sterilization area, the penetration force is weak, the UVC area is almost completely absorbed in the atmosphere, the ground reaching amount is small, the transmission capacity can only reach the horny layer of the skin, and the skin cannot be damaged; UVB has the strongest action on skin, can denature nucleic acid or protein in epidermal cells of the skin, and generates acute dermatitis, namely sunburn (erythema or burn); UVA can oxidize the reduced melanin in the epidermis to directly tan the skin, has strong penetrating power, slow and lasting effect and accumulative property, can cause skin aging after a long time, and increases the damage of UVB to the skin.
Sunscreen has become an important link in skin care, and sunscreen products on the market are classified into spray type, oil-in-water type, water-in-oil type and shaking-shaking type according to the product formulation, and are classified into chemical sunscreen products and physical sunscreen products and products combining chemical and physical sunscreens according to the type of sunscreen used. Among them, the shaking preparation is usually refreshing in skin feeling and good in water resistance. From the safety point of view, people prefer physical sun-proof products. However, products mainly based on physical sun protection usually have thick skin feel and are easy to dry, the physical sun protection used alone hardly achieves a high sun protection index, and a false-white phenomenon after being smeared is obvious, so that the experience feel of the products in use is greatly influenced. In addition, the shake-shake dosage form usually needs specific equipment to realize variable filling while stirring during filling, so that the problem of poor uniformity of products is avoided, troubles are caused to production, and the stability of the product quality is greatly tested.
Patent CN109394588A discloses a sunscreen composition, a sunscreen product, a preparation method and an application thereof, wherein the sunscreen composition comprises the following components in parts by weight: 0.1 to 8.0 parts of sandalwood seed oil, 0.1 to 10.0 parts of calabash seed oil, 0.1 to 12.0 parts of cyperus oil and 0.1 to 8.0 parts of bitter tree seed oil. The sunscreen composition provided by patent CN109394588A is composed of components containing natural plant components, has characteristics of refreshing, quick absorption, good dispersibility, strong stability, good spreadability, good sunscreen effect, high SPF value, water resistance and moisture retention capability, is easy to be evenly applied on the surface of skin, and is not easy to rub mud and ball; and also has anti-inflammatory, free radical scavenging, and anti-erythema effects. The patent CN109394588A provides a sunscreen product containing a large amount of chemical sunscreen agent, which is low in safety.
