Science
Mechanism of Action
On the skin, Diisooctyl Adipate imparts a smooth, lubricating feel, significantly improving the spreadability and application of cosmetic products. It contributes to skin conditioning by forming a protective film that helps minimize moisture loss, leaving the skin feeling soft and hydrated. As a solvent, it facilitates the dissolution and even dispersion of other ingredients, such as UV filters, which is crucial for optimizing overall formulation stability and performance.
