Water-soluble UVA and UVB filter. Highly stable, does not degrade in sunlight but protects other UV blocking agents from UV-induced degradation. Benzophenone-4 is easily 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. Only short UVA (UVA-2, 290-360 nm) but not long UVA are filtered.


Benzophenone-4 is widely used to safeguard cosmetics and personal care products from deterioration by absorbing, reflecting, or scattering UV rays. Benzophenone ingredients absorb and dissipate UV radiation, which serves as a protection for cosmetics and personal care products. Water-soluble UVA & UVB filter.
