About

1-methyl-4-methylethenyl-cyclohexene Sulfurized is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Sulfurized terpenes are associated with both potent sensitization potential and the generation of reactive sulfur compounds during storage or use. The unsaturated cyclohexene ring contributes to reactivity while the sulfurization introduces additional allergenic risk factors recognized by EU dermatological reviews. This ingredient type typically appears on IFRA restricted lists due to sensitization and phototoxicity concerns associated with sulfur-containing fragrance materials.
