Science
Mechanism of Action
This ingredient functions as a Hydrophobically modified Ethylene oxide Urethane (HEUR) thickener. Its structure consists of a long water-loving backbone with branched oil-loving ends; these ends anchor to other oils and surfactants in the formula to create a reversible 3D network that provides a film-forming effect and unique shear-thinning properties upon application.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Patented research indicates that at levels between 0.1% and 1.5%, the polymer shows selective deposition on damaged keratin surfaces, improving skin barrier perception.
- 02 Studies on aqueous compositions at 0.5% concentration demonstrate over 90% light transmittance, confirming its utility in high-clarity, high-aesthetic serums.
Transparency
Dusting Analysis
Because this is a functional structuring agent rather than an active, its presence at low levels (0.1%+) is technically sufficient to alter formula rheology, though premium 'shape-memory' effects typically require slightly higher concentrations.
The Formula
Formulation
Stability
Highly stable across a broad pH spectrum and more salt-tolerant than traditional carbomers. It does not require alkaline neutralization to reach peak viscosity.
Synergies
- Micellar systems
- Oil-in-water emulsions
- Liquid crystal structures
Conflicts
- Extremely high electrolyte concentrations
- Strong oxidizing agents
Safety
Safety Profile
Its exceptionally high molecular weight prevents it from penetrating the skin barrier, making it inherently non-irritating and safe for leave-on use.
