Contraindications, precautions for use

As a recent UV filter on the market, bis-ethylhexyloxyphenol methoxyphenyl triazine has limited documentation on its long-term adverse effects.

However, current data indicate a good tolerability profile. Although rare cases of skin irritation have been reported, it is considered safe and suitable for all skin types, including the most sensitive.

Additional studies in vitro have shown that it does not exhibit intrinsic estrogenic or androgenic activity, unlike some older sunscreen filters.

Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine is a next-generation chemical/organic UV filter known for its efficacy in absorbing UV rays between 280 and 400 nm. At low concentrations in skin and hair care, it helps prevent sun-induced damage. It provides high photostability and enhances the stability of other light-sensitive UV filters.
