Avobenzone Biological Activity
| Description |
Avobenzone is an oil soluble ingredient used in sunscreen products
to absorb the full spectrum of UVA rays and a dibenzoylmethane
derivative.Target: OthersAvobenzone is an oil soluble ingredient used in
sunscreen products to absorb the full spectrum of UVA rays and a
dibenzoylmethane derivative. It can degrade faster in light in
combination with mineral UV absorbers like zinc oxide and titanium
dioxide, though with the right coating of the mineral particles this
reaction can be reduced. A manganese doped titanium dioxide may be
better than undoped titanium dioxide to improve avobenzone's stability.
It reacts with minerals to form colored complexes. Manufacturers of
avobenzone, like DSM recommend to include a chelator to prevent this
from happening. They also recommend to avoid the inclusion of iron and
ferric salts, heavy metals, formaldehyde donors and PABA and PABA
esters[1]. |
