What is UV-9?

UV-9, chemically known as 2-hydroxy-4-n-octyloxybenzophenone, is a widely used UV absorber belonging to the benzophenone class of compounds. In the field of chemical raw materials and polymer materials science, UV-9 plays a vital role, especially in plastics, coatings, adhesives and personal care products, for protection against UV-induced degradation and aging.

The chemical structure of UV-9 contains a benzene ring and a ketone group, as well as a hydroxyl group (-OH) and a longer alkoxy chain (n-octyloxy) attached to the benzene ring. This specific structure gives it good light stability and UV absorption ability, especially for UVA band (about 320-400 nanometers) light with high absorption effect. Its molecular formula is C18H22O3 and its molecular weight is 286.36 g/mol.

UV-9 Uses

1. Plastics and rubber industry
Anti-aging protection: UV-9 can effectively absorb ultraviolet rays in the wavelength range of 290-400nm, significantly reducing the photo-oxidative degradation of plastics (such as PE, PP, PVC) and rubber products caused by ultraviolet irradiation, preventing material discoloration, strength reduction and embrittlement and extend the service life of the product.
Application of transparent products: For plastic products that need to maintain transparency, such as films, sheets, and transparent packaging materials, UV-9 is an ideal choice because of its good transparency.

2. Coatings and paints
Enhanced outdoor weather resistance: In the fields of architectural coatings, ship paint, automobile paint, etc., the addition of UV-9 can significantly improve the weather resistance of the coating, prevent fading, powdering and cracking of the coating caused by ultraviolet rays, and maintain bright colors and structure Integrity.
Wood protection: Used as a protective coating for wooden furniture and outdoor wooden structures, UV-9 can effectively prevent the aging and cracking of wood due to ultraviolet radiation and extend the service life of the wood.

3. Cosmetics and personal care products
Sunscreen formula: In sunscreen, isolation cream and other cosmetics, UV-9 is used as a sunscreen agent in the UVA segment. It can absorb high-energy UVA radiation and prevent skin from sunburn, tanning and photoaging. It is an indispensable ingredient in sunscreen products. one.
Skin care products: In anti-aging and whitening products, UV-9 helps protect skin health and reduce the formation of spots by preventing skin damage caused by ultraviolet rays.

4. Agricultural film
Light control: Adding UV-9 to agricultural plastic films can control the amount of transmitted ultraviolet rays, protect crops from ultraviolet damage, and at the same time adjust light conditions to promote crop growth.

5. Adhesives and Sealing Materials
Stable performance: Used as adhesives and sealing materials for outdoor use, UV-9 can prevent performance degradation caused by ultraviolet rays, maintain adhesion and elasticity, and is suitable for roof waterproofing, building sealing, etc.

UV-9 Prominent Applications in Cosmetics

1. High-efficiency UVA protection
UV-9 specializes in absorbing ultraviolet rays in the UVA band (320-400 nanometers). Although this part of ultraviolet rays is not as direct as UVB to cause sunburn, it can penetrate into the dermis of the skin and cause skin photoaging, such as the formation of wrinkles, sagging, and spots. Therefore, UV-9 is used as the main UVA protection ingredient in sunscreens, primers and other sunscreen cosmetics to provide comprehensive anti-photoaging protection for the skin.

2. Photostability and long-lasting protection
UV-9 has good photostability and chemical stability. Even under long-term sunlight exposure, it can maintain its ability to absorb ultraviolet rays and provide long-lasting protection for the skin. This stability enables sunscreen products containing UV-9 to effectively resist ultraviolet rays for a long time, reduce the frequency of re-application, and improve user experience.

3. Formula compatibility
As an organic chemical raw material, UV-9 has good compatibility in cosmetic formulas and can be integrated with a variety of emulsification systems, oils, and other sunscreens (such as UVB absorbers) to form a stable and efficient sunscreen system. This makes it highly practical in the development of sunscreen products. It can be used alone or in combination with other sunscreens to achieve a broad-spectrum sunscreen effect.

4. Transparency and skin feel
The molecular design of UV-9 makes it transparent in the visible light range, without affecting the transparency or color of cosmetics, and is suitable for all types of transparent or colored sunscreen products. In addition, it feels lighter on the skin and does not leave a heavy or greasy feeling, which improves the comfort and acceptance of cosmetics.
