About
Specialty ester compound used as a fragrance and conditioning agent.
Dimethylbutyl crotonate (3-methyl-2-butenyl dimethylacrylate) is an unsaturated ester of crotonic acid. The crotonate structure contains an alpha-beta-unsaturated carbonyl system, which can be reactive. Limited toxicological data is available for this specific compound in cosmetic contexts. Not specifically listed in EU Annex II (banned) or Annex III (restricted) under Regulation (EC) No 1223/2009, but given the structural alerts and lack of safety data, caution applies. The compound is used primarily as a fragrance or flavor material.
Known concerns
- Insufficient toxicity data
- Structural alerts for reactivity
- Unknown sensitization potential
