Who it's for
Description
A chemical sunscreen agent that gives strong protection in the UVB (280-320nm) range with its peak protection at 306 nm. Its special property is that unlike most sunscreen agents, it is not oil but water soluble, so it is ideal to create light, oily skin compatible formulas. It is also fairly photostable and can be used to protect other less stable UV filters (like famous UVA blocker, avobenzone) in the formula. It is approved worldwide and can be used up to 4% in the US and up to 8% in the EU.
