Science
Mechanism of Action
This ingredient functions by forming a breathable, lightweight occlusive film on the stratum corneum, significantly reducing trans-epidermal water loss (TEWL). Its medium-chain fatty acid structure (C8-C12) allows it to act as a biocompatible penetration enhancer for other active ingredients while offering mild antimicrobial benefits by disrupting the lipid membranes of potential surface pathogens.

Key findings
- 01 A randomized controlled trial demonstrated that a 100% concentration application twice daily over 14 days resulted in a 74% increase in skin hydration for patients with senile xerosis.
- 02 Safety assessments by the CIR confirm the ingredient remains non-irritating and non-sensitizing even at concentrations as high as 95.6% in leave-on facial formulations.
Transparency
Dusting Analysis
As a primary emollient and carrier, it is typically used in significant functional percentages (1-20%+) to achieve the desired texture and barrier support. Concentrations below 1% in moisturizers may indicate it is being used merely for label claims or as a processing aid rather than for its clinical hydration benefits.
The Formula
Formulation
Stability
Highly resistant to oxidation due to its saturated fatty acid profile, ensuring a long shelf life. Stability is compromised in high-heat environments or extremely alkaline conditions, which can trigger hydrolysis.
