Physical description & handling notes

Solid
Stable under recommended storage conditions.
pKa = 1.99 /sulfuric acid moiety/
When exposed to UV ecamsule undergoes reversible photoisomerization followed by photoexcitation. The absorbed UV is then released as thermal energy, without penetrating the skin, thereby protecting the skin from UV exposure.
