Application:
2-Hydroxy-4-Methoxybenzophenone-5-Sulfonic Acid Hydrate (UV Absorber Sulisobenzone; Benzophenone-4; UV-284) (CAS: 4065-45-6) is a kind of ultraviolet UVB sunscreen. It is a water-soluble chemical sunscreen. It is allowed to be used in the European Union. It is irritating to the skin and eyes. Although it will not be absorbed by the skin, it will increase the skin's resistance to other chemicals in the sunscreen. Material absorption. Product Features Ultraviolet absorber BP-4 is a benzophenone type ultraviolet absorber, mainly for 280nm-360nm ultraviolet rays. The ultraviolet absorber BP-4 is easily soluble in water, and the aqueous solution is acidic, so it needs to be neutralized in the process of using Chemicalbook. If the pH of the solution is greater than 9, the absorption wavelength will be narrowed. It is mainly used in skin care products such as daily sunscreen to prevent skin aging caused by ultraviolet rays. It can also be used in water-based paints, dyes, and washing products. Uses: UV absorber BP-4 belongs to benzophenone compounds. It is a white or light yellow powder at room temperature, which can effectively absorb ultraviolet light of 285~325Im. It is a kind of high absorption rate, non-toxic, non-photosensitizing, non-teratogenic, and good light and heat stability. The broad-spectrum UV line absorber is widely used in sunscreen cream, honey, lotion, oil and other cosmetics. Sunscreen is generally applied to the surface of the skin and has a sunscreen effect to protect the skin. The ultraviolet absorber BP-4 has good light and heat stability, and is widely used in sunscreen cosmetics such as sunscreen creams, creams, honey, lotions, oils, etc. A water-soluble broad-spectrum ultraviolet absorber with a maximum absorption wavelength of 288nm, good light and thermal stability, high absorption efficiency, and can absorb UV-A and UV-B at the same time. In the water phase of cosmetics, it is widely used in sunscreen creams, creams, honeys, lotions, oils and other cosmetics, non-toxic, no allergenic and teratogenic side effects, and the addition amount is 5-8%.Sufficient Capacity: Sufficient facilities and technicians
