Science
Mechanism of Action
This ingredient operates on multiple levels: as an emulsifier, it expertly integrates disparate oil and water phases into stable, homogeneous mixtures. On the skin, it functions as an emollient, drawing and retaining moisture to improve suppleness and softness. Furthermore, it establishes a subtle, protective film on the epidermal surface, which not only prevents transepidermal water loss but also shields the skin from environmental stressors, contributing to sustained hydration.

Stability
Polyglyceryl Dimer Soyate belongs to a family of polyglyceryl esters known for exhibiting robust thermostability and resistance to acidic conditions. For optimal emulsion stability, initial mixing during formulation can be carried out at a pH exceeding 7.0, with the final pH subsequently adjusted to the range of approximately 5.0-7.5.
