Science
Mechanism of Action
By lowering the interfacial tension between water and oil, this transester forms a hydrophilized lipid film on the stratum corneum. This microscopic film structures water into a 'cushion' capable of retaining six times its weight in moisture, significantly reducing transepidermal water loss while providing a smooth sensory profile.

Key findings
- 01 Manufacturer data (Gattefossé) indicates that concentrations between 2.5% and 6.0% create a measurable 'water cushion' effect, optimizing moisture retention.
- 02 A 2016 CIR safety assessment confirmed that concentrations up to 2.0% are non-irritating and non-sensitizing in diverse cosmetic applications.
Transparency
Dusting Analysis
While this ingredient functions as an emulsifier at lower levels (0.5-2%), therapeutic hydration and the signature 'water cushion' sensory effect require a concentration of at least 2.5%.
