Usage:
Sunscreen agent-1789 is the most effective fat soluble UVA filter and is a safe and effective UVA sunscreen approved by the US FDA for sale on the counter. It can effectively block UVA, thereby increasing the SPF value of sunscreen products. It can improve the efficacy of sunscreen products when used in combination with UVB filters, and BL-200 has the best effect when used in combination with octyl methoxycinnamate. BL-200 can increase its stability in the product. It has an extremely effective protective and repairing effect on human skin.
Application:
This product is soluble in oil and can be formulated into a cream using the usual method. However, the product turns red when it encounters metal ions, so other components such as formula water should not introduce metal ions. The equipment should be made of pure stainless steel, and an appropriate amount of EDTA-2Na should be added to the formula water phase to chelate with metal ions.
Product name: Avobenzone INCI Name: BUTYL METHOXYDIBENZOYLMETHANE Molecular Formula: C20H22O3 Molecular Weight: 310.39 Appearance: White fine powder Purity: 99% CAS NO.: 70356-09-1 EINECS No.: 274-581-6 Supplier: ZHENYIBIO Avobenzone is an oil-soluble ingredient used in sunscreen products to absorb the entire spectrum of UVA rays.Avobenzone powder is a derivative of dibenzoylmethane.Avobenzone exists in the ground state as a mixture of enol and ketone forms,which is beneficial to the chelated enol.Compared with many organic sunscreens,its ability to absorb a wider range of ultraviolet wavelengths has allowed avobenzone uses in many commercial formulations sold as "broad-spectrum" sunscreens.Avobenzone in skin care can absorb a wider range of ultraviolet wavelengths.It absorbs ultraviolet-A (380-315 nm, related to long-term skin damage) and ultraviolet-B (315-280 nm that cause sunburn) rays.Avobenzone for skin protection from sunscreen.
Application field Avobenzone is a sunscreen blocker. Avobenzone is a topical, broad range UV protector and blocks UVA I, UVA II, and UVB wavelengths, thereby limiting the impact of UV rays on skin. Technical Specification Appearance: White or pale yellow crystalline powder Absorptivities at 360nm do not differ by more than 3.0% Loss on drying 0.5% max Assay (GC) 95.0~105.0% Impurity (GC) Individual impurity: 3.0% max Total impurity: 4.5% max Residual solvents Methanol: 3000ppm max
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.

JADEWIN UV 1789(AVOBENZONE) is broad spectrum UV absorber with effective absorbtion in both UVA and UVB region JADEWIN UV 1789(AVOBENZONE) is suggested to be used in sunscreen products and formulation of protective hair-care, medicated Skin-Care and also to quench phototoxic skin reactions initiated by weak phototoxic materials. JADEWIN UV 1789(AVOBENZONE) is incompatible with formaldehyde,formaldehyde donor preservatives and heavy metals Pink-Orange Color with Iron, formulation with PABA and its esters develop a yellow color. It can form complexes with aluminium above PH.7. So JADEWIN UV 1789(AVOBENZONE) should avoid Iron and Ferric Salts, Heavy metals,Formaldehyde donors, PABA and PABA esters.
Butyl Methoxydibenzoylmethane, also known as Avobenzone, the CAS Number is 70356-09-1, which is an efficient broad-spectrum oil-soluble UVA filter. Long-term use can effectively reduce wrinkles, stains, rough skin and other problems, and can prevent skin cancer. Mainly used in cosmetic sunscreens, sunscreens and other products, and can also be used as a photodegradation stabilizer to prevent cosmetics and perfumes.
2-Phenylbenzimidazole-5-sulfonic acid, also called Ensulizole, the abbreviation is UV-T, which is a high-efficiency UVB absorber, with an ultraviolet absorption rate of at least 920 at about 302nm, and can also absorb a small part of the UVA band. It belongs to water-soluble chemical sunscreens. It is often used in combination with other ingredients such as avobenzone, titanium dioxide, zinc oxide, or tinosorb. Its protective power and quality of protection do not gradually decrease over time when exposed to sunlight, thus somewhat mitigating the breakdown of other UVB blockers in sunscreens. The non-greasy texture also converts ingested UV radiation into less harmful infrared radiation and heat.
