OCTRIZOLE.

Avoid CAS 3147-75-9 / UV ABSORBER

Octrizole functions as a chemical UV filter, designed to protect the skin from harmful ultraviolet radiation across both UVA and UVB spectrums. Its primary role is to prevent UV-induced skin damage and mitigate the signs of photoaging, making it suitable for sun protection formulations.

Summary

UV absorber Photoprotective agent

Science

Mechanism of Action

Octrizole operates by absorbing harmful UVA and UVB radiation, effectively acting as a broad-spectrum ultraviolet filter. This absorption mechanism prevents these damaging rays from penetrating the skin, thereby reducing cellular stress and minimizing photoaging effects.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

Octrizole has been identified in Germany as a Substance of Very High Concern (SVHC) due to its classification as very persistent and very bioaccumulative (vPvB). Cosmetics Europe has initiated a 'Call for Interest' regarding its potential regulatory defense. While not assessed by CIR for cosmetic safety, it is listed by the FDA as a Food Contact Substance (FCS) for specific packaging materials under 21 eCFR 178.2010.

Our Assessment

Verdict

Avoid

Despite its capacity as a UV absorber, Octrizole's classification as a Substance of Very High Concern (SVHC) due to very persistent and very bioaccumulative (vPvB) properties, coupled with an 'not reviewed' CIR status, necessitates its avoidance in precision skincare formulations.
