Science
Mechanism of Action
Creates a hydrophobic protective film on the skin surface that reduces transepidermal water loss while simultaneously acting as a non-aqueous thickening agent. Its large molecular structure prevents dermal penetration, making it function purely at the surface level to enhance product slip, texture, and barrier properties.
Research
Clinical Evidence
High confidenceN/A
Key findings
- 01 Non-sensitizing and non-irritating in human patch tests when used in lip products at maximum concentrations
- 02 Zero sensitization or irritation responses in human dermal studies at full concentration
Transparency
Dusting Analysis
As a functional polymer used for viscosity control and film formation, this ingredient serves essential formulation purposes rather than marketing benefits, making dusting unlikely.
The Formula
Formulation
Stability
Exceptionally stable across all cosmetic pH ranges and standard temperature conditions due to its chemically inert polyolefin structure
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
FDA approved as indirect food additive under 21 CFR 177.1570. Large molecular weight prevents dermal absorption, rendering it biologically inert.
