ETHYLBENZENE.

Avoid CAS 100-41-4 / PERFUMING

Ethylbenzene is an aromatic hydrocarbon recognized primarily for its industrial solvent properties rather than any beneficial dermatological actions. It is readily absorbed through human skin and is associated with significant irritant and toxicological concerns, making it unsuitable for skincare formulations.

Summary

Science

Mechanism of Action

Ethylbenzene does not possess any beneficial mechanism of action on the skin. Its interaction is characterized by solvent effects that can compromise the skin barrier and induce irritation. Once absorbed transdermally, it is metabolized internally, contributing to its systemic toxicological profile.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

The International Agency for Research on Cancer (IARC) classifies ethylbenzene as possibly carcinogenic to humans (category 2B), though regulatory bodies in the US and EU do not classify it as a carcinogen. The US EPA suspended its assessment in 2019. It is a documented skin and serious eye irritant. Prolonged dermal exposure can lead to drying, scaling, and blistering of the skin. Its application as a solvent in consumer or professional sectors is not recommended, and its presence in cosmetic formulations is generally considered an impurity due to its hazardous characteristics.
