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.

Phase transfer catalysts for organic synthesis, curing accelerators for polymer polymerization, organic electrolytes in electronics industry, oil field chemicals, molecular sieve template agents, phase change cold storage materials, high performance liquid chromatography analysis reagents, surfactants, descaling agents, adsorption agents, oil-displacing agents, etc.

Benzalkonium bromide, also known as benzalkonium bromide and Bromogeramine, is a kind of quaternary ammonium salt cationic surface active broad-spectrum bactericide. It has the characteristics of strong and rapid bactericidal effect, low toxicity, no irritation to skin and tissue, strong penetration, no corrosive effect on metal and rubber products, etc.

Lithium is a metal element with the element symbol Li. The corresponding elemental substance is silver white soft metal, which is also the metal with the lowest density. It is used in atomic reactors, light alloys and batteries. Lithium itself is not as polarizable as other lithium ions or alkali compounds, because lithium itself is not as polarizable as other lithium ions. This affects the stability of it and its compounds.

Nickel is located in group 10 (VIII) and is the third element in the special triples (Fe, Co, Ni) of the first series of transition elements. Nickel is a hard, silvery white, malleable metal block or gray powder. Nickel powder is pyrophoric and can spontaneously ignite. It may react violently with titanium, ammonium nitrate, potassium perchlorate and hydrodicarboxylic acid. It is incompatible with acids, oxidants and sulfur. The chemical and physical properties of nickel, especially its magnetism, are similar to those of iron and cobalt. Some acids attack nickel, but it also provides good protection against air and sea water corrosion. This makes it very suitable for electroplating other metals to form a protective coating. Nickel is also an excellent alloy metal, especially iron, which can be used to make stainless steel and protective armor for military vehicles. It is extensible and can be drawn into lines. About a pound of nickel metal can be pulled to about 200 miles of thin wire.
