Product Introduction:
Water-soluble UVA and UVB filter. Only short UVA (UVA-2, 290-360 nm) but not long UVA are filtered. Highly stable, does not degrade in sunlight but protects other UV blocking agents from UV-induced degradation. Benzophenone-4 is completely soluble in water, propylene glycol, glyerin, ethanol and isopropyl alcohol. Due to its high acidity (pH < 2.5 in a 1% solution), a neutralizing agent (e.g. triethanolamine) must be added to elevate the pH to >3.5.
Benzophenone ingredients absorb and dissipate UV radiation, which serves to protect cosmetics and personal care products. As part of sunscreen products, which are OTC drugs in the United States, Benzophenone-3 (Oxybenzone) and Benzophenone-4 (Sulisobenzone) protect the skin from the harmful effects of the sun.
Product Functions:
1. Water-soluble UVA & UVB filter. Used primarily as UVA filter.
2. Should be combined with other sunscreens (e.g. octocrylene, homosalate, ethylhexyl salicylate, OM-cinnamate) for effective UVB protection. Benzophenone-4 provides inadequate UVB protection when used alone.
3. Does not penetrate the skin to a large degree, but enhances the ability of other ingredients to penetrate.
4. Helps to stabilize UV sensitive formulations such as hair dyes, hair sprays and color enhanced formulations.
5. Provides protection of colorants against fading and help stabilize fragrances and active ingredients against oxidation.
Product Applications:
Sun care products, color cosmetics with sun protection, various cosmetics & fragrances for product protection.
