About

Tetrabutyl Ethylidenebisphenol is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Tetrabutyl ethylidenebisphenol is a bisphenol-A analog bearing four butyl substituents and an ethylidene bridge between the phenolic rings. Bisphenol compounds are under increasing regulatory scrutiny in the EU due to endocrine disruption concerns. The ingredient carries H315 (skin irritation), H319 (eye irritation), and H335 (respiratory irritation) classifications. While not currently listed on EU cosmetic Annex II/III restrictions, its bisphenol structure places it under regulatory watch.
