Diisopropyl Adipate
Ingredient Info
Diisopropyl adipate is a lightweight synthetic oil derived from adipic acid. In skincare, it acts as an emollient and penetration enhancer, helping other active ingredients absorb into the skin while providing a smooth, non-greasy feel.
Benefits
- Improves absorption of active ingredients like retinoids into the skin
- Provides lightweight moisture without a heavy or occlusive feel
- Helps stabilize and deliver other skincare actives more effectively
Potential concerns
- May increase skin penetration of other ingredients, which is beneficial for actives but requires careful formulation
- Suitable for most skin types, but those with very sensitive skin should monitor tolerance
Science: Research shows diisopropyl adipate acts as a penetration enhancer for topical actives, particularly retinoids and anti-inflammatory compounds like diclofenac. Studies confirm it moderately enhances skin permeation compared to heavier oils, making it useful in formulations designed for better ingredient delivery.
