Science
Mechanism of Action
Acts as a solvent system that dissolves fragrance components and improves product texture, while providing mild emollient properties through its diester structure. As a lactic acid derivative, it may offer subtle skin-softening benefits without functioning as an active exfoliant.

Dusting Analysis
Primarily used as a fragrance and solvent component rather than an active ingredient, making dusting practices uncommon in this application category.
The Formula
Formulation
Stability
Maintains stability as a liquid but undergoes hydrolysis in extreme pH environments, breaking down into lactic acid, butyric acid, and butanol components. Requires protection from light and heat exposure.
