Science
Mechanism of Action
This high-molecular-weight ester utilizes a unique thixotropic network to create a breathable, occlusive barrier. Its structure, featuring phytosteryl and behenyl groups, allows it to anchor firmly to the skin surface, significantly increasing water-holding capacity and refracting light for a high-gloss effect while stabilizing pigments within the formula.
Research
Clinical Evidence
High confidence11.25%
Key findings
- 01 In vivo sensory evaluations confirmed that at an 11.25% concentration, this ingredient creates a uniform, comfortable deposit that improves glide and color transfer resistance.
- 02 L'Oreal clinical assessments identified a 3% to 20% range as the gold standard for achieving high-shine remanence without tackiness in both liquid and solid anhydrous formats.
Transparency
Dusting Analysis
Because this ingredient is primarily used for its sensory profile and film-forming properties, concentrations below 3% may fail to provide the characteristic high-shine and barrier-repair benefits, potentially serving only as a label claim.
The Formula
Formulation
Stability
Highly stable against oxidation due to its saturated dimer structure; preferred over natural oils for long-term shelf stability at room temperature.
Synergies
- Pigment dispersions
- Anhydrous waxes
- Emollient oils
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
The CIR Expert Panel classifies this as a non-penetrating, high-molecular-weight ingredient, making it exceptionally safe for topical use, including lip applications where ingestion risk is higher.
