Safety score · 0–100
Caution
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
An isobutylethylidene bisphenol monomer used in polymer chemistry, sharing structural and endocrine-disruption concerns with the bisphenol class and lacking a recognized cosmetic safety profile.
Skin benefits
- Functional bisphenol-class monomer used in some polymer and resin chemistries
- Provides polymer chain rigidity in non-cosmetic industrial uses
Known concerns
- Bisphenol-class compounds are widely flagged for endocrine disruption potential
- Not a recognized cosmetic INCI ingredient with established safety review
- Structural similarity to bisphenol A raises estrogenic activity concerns
- Potential for skin absorption with poorly characterized chronic exposure data
