Science
Mechanism of Action
This ingredient works by forming a hydrophobic, occlusive barrier on the stratum corneum, effectively locking in moisture and preventing transepidermal water loss (TEWL). Its unique alkyl modification enhances its lipophilicity, allowing it to integrate seamlessly with organic lipids to improve the spreadability and sensory profile of topical formulations.

Key findings
- 01 Human clinical repeat insult patch tests (HRIPT) confirm that this polymer is non-sensitizing and non-irritating to the skin.
- 02 Safety assessments by the Cosmetic Ingredient Review (2021) indicate the molecule is not dermally absorbed due to its high molecular weight.

Dusting Analysis
While often used as a texture enhancer at lower levels, therapeutic barrier protection is typically observed at higher concentrations. Formulations using this at negligible levels (below 0.5%) may be utilizing it for marketing claims rather than functional skin conditioning.
The Formula
Formulation
Stability
Demonstrates exceptional stability against oxidation and remains chemically inert across a broad pH spectrum. It is ideally suited for anhydrous systems or the oil phase of emulsions.
Synergies
- Organic oils
- Mineral UV filters
- Lipophilic active ingredients
Conflicts
- Highly polar aqueous systems
- Water-based gels without secondary emulsifiers
Safety
Safety Profile
