Science
Mechanism of Action
As an electrophilic compound, Dibutyl Maleate interacts with skin proteins via Michael-type conjugate additions. It can also enhance contact sensitization by facilitating dendritic cell trafficking and increasing cytokine production.

Clinical Evidence
Low confidenceN/A
Key findings
- 01 Human patch tests at 0.1% reported sensitization reactions.
- 02 Direct skin application of 0.2-0.3 mL caused slight burning, prickling, and erythema (15-20 cm²) within 30-60 minutes.
- 03 Animal studies indicate enhanced contact hypersensitivity.

The Formula
Formulation
Stability
Chemically stable under recommended conditions, but transposes to fumaric acid dialkyl ester with heat or in presence of acids/bases. Contact with acids, bases, or strong oxidizing agents can lead to violent, exothermic reactions.

- strong oxidizing agents
Safety
Safety Profile
Dibutyl Maleate is not CIR reviewed and is considered an irritant and skin sensitizer, causing redness and burning even at 0.1% in humans. FDA listings for this ingredient are solely for industrial uses in adhesives and coatings, not direct cosmetic application.
