About
TRIMETHYL-1-CYCLOHEXENYLBUTANE-1,3-DIONE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
Trimethyl-1-Cyclohexenylbutane-1,3-Dione is a 1,3-diketone with a trimethylcyclohexenyl substituent. The 1,3-diketone moiety can undergo tautomerization to the enol form, which influences reactivity and potential for skin interaction. The cyclohexenyl group is lipophilic, while the diketone is more polar, creating an amphiphilic character. It is not listed in EU Annex II (banned substances) or Annex III (restricted substances) of the Cosmetics Regulation. The 1,3-diketone structure can act as a ligand for metal ions.
Skin benefits
- Fragrance material with complex, aromatic notes

Known concerns
- 1,3-Diketone structure may undergo enolization affecting reactivity
- Metal binding potential from diketone functionality
- Limited comprehensive skin safety data
