Science
Mechanism of Action
This ingredient acts as a crystal-growth inhibitor, preventing the 'blooming' or crystallization of other waxes to ensure a perfectly smooth application. It forms a flexible, breathable film that anchors active ingredients—particularly UV filters—while suppressing transepidermal water loss through its refined lipid structure.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Demonstrated to significantly boost SPF values at 3-15% concentrations by optimizing the homogeneity of UV filter distribution.
- 02 Identified as an effective emollient for reducing TEWL and stabilizing emulsion architecture at 1-15%.
- 03 Validated as a non-sensitizing primary structuring agent in lip care at 20% for prolonged hydration.

Dusting Analysis
This ingredient is typically used at functional levels (1-20%) to achieve specific textural or SPF-boosting objectives; concentrations below 1% generally fail to provide the required structural or barrier benefits.
The Formula
Formulation
Stability
Highly resistant to oxidation and hydrolysis; features a high melting point (80-90°C) which provides excellent thermal stability for stick and balm formats.
Synergies
- Mineral UV filters
- Chemical UV filters
- Vegetable waxes
Conflicts
- Cold-process formulations (requires heating to 85°C+)
Safety
Safety Profile
Classified under the CIR safety assessment for Fatty Acids and Fatty Acid Salts; noted for its lack of sensitization even at high concentrations.
