OCTYL/ISOOCTYL BENZOTRIAZOLYL T-BUTYLPHENOLPROPANOATE

58

Safety score · 0–100

Moderate

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Benzotriazole UV absorbers (BUVAs) are a well-studied class including well-known cosmetic filters such as drometrizole trisiloxane and ethylhexyl triazone. This t-butyl phenylpropanoate derivative belongs to the same chemical family and is intended to function as a UV filter or stabiliser. The benzotriazole scaffold has been subject to some environmental scrutiny in the EU due to detection in aquatic environments. The specific octyl/isooctyl alkyl chain variation has limited dedicated toxicological study, and it falls below the threshold for specific EU CosIng restriction despite its UV filter classification in some jurisdictions.

Skin benefits

  • UV-absorbing properties for sun-protection formulations
  • Antioxidant stabiliser helping protect active ingredients

Known concerns

  • Limited specific toxicological data for this exact compound
  • Benzotriazole class under EU environmental review due to aquatic detection
  • Potential endocrine activity flagged for some benzotriazole UV absorbers
  • No specific EU CosIng entry with concentration limits identified
