About
An acetal derived from cinnamaldehyde that shares structural alerts for skin sensitization despite acetal modification.
Cinnamaldehyde dimethyl acetal is structurally related to cinnamaldehyde, a well-documented skin sensitizer. While acetal formation can reduce direct reactivity, metabolic hydrolysis may regenerate cinnamaldehyde on skin. Not currently restricted under EU cosmetics law, but the structural alert warrants caution in leave-on products for sensitive skin.
Skin benefits
- Fragrance material with spicy, cinnamon-like notes
Known concerns
- Potential skin sensitization (structural analogue to cinnamaldehyde)
- May hydrolyze to cinnamaldehyde on skin
