Science
Mechanism of Action
The acetylation of hydrogenated vegetable glycerides creates a hydrophobic molecule, enabling it to form a protective barrier on the skin surface. This film prevents moisture evaporation and provides a non-greasy emollient feel by filling gaps between skin cells.

Key findings
- 01 General safety and occlusive benefits for related glycerides are noted across a broad range (0.0001-70%).
- 02 Related acetylated lipids showed high comedogenicity at 100% (4-5) but significantly reduced potential (1) when diluted below 2.5%.

The Formula
Formulation
Stability
Highly stable due to hydrogenation, which prevents rancidity and oxidation. Acetylation also enhances resistance to hydrolysis compared to simpler esters.
Conflicts
- Strong oxidizing agents
- Highly acidic environments (may cause slow hydrolysis of the acetyl group)
