Arbutin is a hydroquinone glycoside compound, its chemical name is 4-Hydroquinone-alpha-D-glucopyranoside (4-Hydroquinone-alpha-D-glucopyranoside), which exists in plants such as bearberry and bilberry. It is a natural whitening active substance emerging that is non-irritating, non-allergenic and compatible. There are two structural and functional functional groups in the molecular structure of arbutin: one is glucose residue; the other is phenolic hydroxyl group. The physical state of �±-arbutin is white to light gray powder, which is easily soluble in water and ethanol.
Avobenzone is an oil-soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays.Avobenzone was patented in 1973 and was approved in the EU in 1978. Its use is approved worldwide.
Pure avobenzone is a whitish to yellowish crystalline powder with a weak odor, dissolving in isopropanol, dimethyl sulfoxide, decyl oleate, capric acid/caprylic, triglycerides and other oils. It is not soluble in water.
Avobenzone absorbs both UV-(380-315 nm that is associated with long term skin damage) and UV-B (315-280 nm that causes sunburn) rays. Avobenzone is known as one of the most effective sunscreen ingredients.
Vitamin A acetate is A fat-soluble vitamin and is referred to as Vitamin A nutritional supplement. Vitamin A is involved in a variety of physiological processes, and Vitamin A deficiency can lead to impaired rod cell function, anemia, decreased immune function, and poor growth. Therefore, Vitamin A fortified foods are widely used in many countries. Vitamin A acetate is A kind of unsaturated esters, oily, easy oxidation, soluble in fat or organic solvent, but insoluble in water, it is difficult to uniformly added in food J, application scope is limited, so after the micro capsule, it can improve the water solubility and stability of it, and form into powder by oil, easy handling and processing progress.
Used for the extraction of spices and essences and as a solvent. Ethyl butyrate can be used in daily chemical fragrance formulations, but the amount is very small. It is widely used in edible flavor formulations, such as bananas, pineapples, etc., and can be formulated with a variety of fruit flavors and other flavors.

Application
Lithium metasilicate is an inorganic compound that has a high resistance to heat and acid. It is used as an additive to zirconium oxide membranes, which are used in membrane separation processes. It has been shown to have a high transport capacity for water vapor and sodium carbonate. This property makes it suitable for use in the clinical setting where it has been shown to have biological properties and clinical relevance.
(-) -Epigallocatechin Gallate CAS NO. 989-51-5 is white crystal, soluble in organic solvents such as DMSO, derived from tea.
(-) -Epigallocatechin Gallate CAS NO. 989-51-5 is the most effective active ingredient in catechins, accounting for about 8% to 13% of the gross weight of green tea, and (-) -Epigallocatechin Gallate CAS NO. 989-51-5 is also the component with the highest content in catechins.
(-) -Epigallocatechin Gallate CAS NO. 989-51-5The ester formed by benzopyran with gallic acid has phenolic antioxidant properties, and (-) -Epigallocatechin Gallate CAS NO. 989-51-5 molecular structure has six adjacent phenolic hydroxyl groups, thus having many properties superior to other catechins.
