Avobenzone (trade name: parsol 1789, eusolex 9020, escalol 517, etc.). Inci Name: butyl methoxydibenzoylmethane is the name of usan. It is a fat soluble component used in sunscreen products and can absorb UVA in all bands (about 315 to 400 nm). It is a derivative of dibenzoylmethane (DBM). Among them, avobenzone has the highest UVA absorption at the wavelength of 357 nm. Compared with other chemical sunscreen agents, it can absorb a wide range of ultraviolet light, so it is widely used in many advertised broad-spectrum sunscreen products.

Peptone is an organic compound. Peptone is a light yellow powder formed by hydrolyzing meat, casein or gelatin with acid or protease and drying, which has a special smell of meat flavor. Peptone can also be formed after protein is decomposed by acid, alkali or protease. One of the initial digestion products of protein in the stomach is peptone.

Tin is one of the earliest metals used by mankind and one of the most widely used metals in industry. It has the excellent characteristics of soft texture, low melting point, strong expansibility, strong plasticity and non toxicity. It is mainly used in the manufacture of solder, tinplate, alloy, chemical products and so on. It is widely used in electronics, information, electrical appliances, chemical industry, metallurgy, building materials, machinery, food packaging, atomic energy and aerospace industry.

Castor oil is the fatty oil extracted from the seeds of castor, a plant of the genus ricinus in the family Euphorbiaceae. It is a clear viscous liquid almost colorless or slightly yellow at room temperature, slightly smelly, light and then slightly pungent. Insoluble in water, soluble in ethanol, benzene and carbon disulfide, freely mixed with absolute ethanol, ether, chloroform or glacial acetic acid, but insoluble in mineral oil. The relative density is 0.956 ~ 0.969 (25 ℃), the refractive index is 1.478 ~ 1.480, the acid value is < = 2.0, the saponification value is 176 ~ 186, and the iodine value is 82 ~ 90. Castor oil is mainly a glyceride of higher fatty acids composed of castor alkyd (12-hydroxyoctadecane-9-enoic acid) and oleic acid. R1, R2 and R3 in the molecule can be the same or different, including 80% ~ 88% castor alkyd, 3% ~ 9% oleic acid, palmitic acid, stearic acid, linoleic acid and linolenic acid, Dihydroxystearic acid, glycerol ester is composed of 68.2% tririci nolein, 28.0% di RICINOLEIN, 2.9% monoricinolein and 0.9% non RICINOLEIN. Ash contains a large amount of calcium, iron and silicon, as well as inorganic elements such as aluminum, copper and magnesium and a small amount of manganese, titanium, nickel and zinc.
