Science
Mechanism of Action
It creates a breathable, non-occlusive film on the stratum corneum to significantly reduce trans-epidermal water loss (TEWL) and soften skin texture. Beyond surface conditioning, it acts as a carrier solvent, enhancing the penetration and uniform distribution of oil-soluble ingredients within a formulation.

Dusting Analysis
As a functional emollient and solvent, Dicetearyl Succinate is typically included at concentrations above 1% to achieve the desired textural impact. It is rarely used as a 'label claim' ingredient at sub-functional levels.
The Formula
Formulation
Stability
Highly stable and resistant to oxidation; maintains integrity better than many natural plant oils. It is susceptible to saponification in environments with a pH exceeding 9.0.
