About
A fruity-green ester with a character reminiscent of tropical fruits, classified as an environmental hazard (H411) requiring careful handling and disposal but not directly restricted in EU cosmetic formulations.
cis-3-Hexenyl 2-methylbutyrate is an unsaturated ester with a distinctive fruity-green odor profile. It carries GHS hazard statement H411 (toxic to aquatic life with long-lasting effects), which requires environmental risk assessment in cosmetic product life-cycle; however it is not listed in EU CosIng Annex III restrictions. It is not considered a strong sensitizer but must be declared as a fragrance allergen in EU cosmetics above threshold levels under Regulation (EC) No 1223/2009.
Known concerns
- H411 — toxic to aquatic life with long lasting effects
- fragrance allergen — EU label declaration required
