Science
Mechanism of Action
It functions as an emollient by forming a protective film, and as a solvent, notably aiding in the solubilization of UV filters within sunscreens. Additionally, it acts as a plasticizer, improving formula spreadability and enhancing the skin penetration of other ingredients.

Stability
Dibutyl Adipate is generally stable with a reported pH of 6.0. It exhibits good compatibility with UV filters like Octisalate and Homosalate, helping to reduce the melting temperature of other ingredients.
Synergies
- UV filters (e.g., Octisalate, Homosalate)
- Lactic acid (enhances skin penetration)
Conflicts
- Oxidizing agents (nitrates, oxidizing acids, chlorine bleaches, pool chlorine)
- Strong oxidizing acids (potential for vigorous exothermic reaction)
- Natural rubber, butyl rubber, EPDM, polystyrene (material incompatibility for handling)
Safety
Safety Profile
The CIR Expert Panel deemed Dibutyl Adipate safe for cosmetic use up to 8%, being non-toxic and non-carcinogenic. While generally well-tolerated, repeated exposure may cause skin drying or flaking, and it should not be applied to open or irritated skin.
