The use of an appropriate Pyrrolidone-based surfactant (N-C1-C20-alkyl substituted pyrrolidone) guarantees the optimal solubilization of substituted Triazine derivatives such as Bis-Ethylhexyloxyphenol Methoxyphenyltriazin. Consequently, it limits or avoids the crystallization phenomena of the UV absorber which cans appear across the time, in cosmetic end-products, above a certain amount and it improves its UV protection efficacy.
