Science
Mechanism of Action
This ingredient functions as a temperature-sensitive molecular 'sponge.' Upon application, skin heat (32°C–37°C) triggers the polymer's hydrophobic blocks to contract, effectively squeezing entrapped water molecules out of the hydrogel matrix and directly into the stratum corneum for immediate, targeted hydration.
Research
Clinical Evidence
Medium confidence12%
Key findings
- 01 Clinical evaluation demonstrates that a 12% concentration successfully creates a photo-polymerized network that releases moisture specifically at skin temperature, significantly outperforming standard humectants in sustained hydration delivery.
Transparency
Dusting Analysis
Because this is a functional structural polymer, concentrations below 1% are typically insufficient to achieve the 'water-drop' or thermo-responsive effect, indicating potential 'label dressing' or dusting.
The Formula
Formulation
Stability
Highly stable in aqueous environments with minimal degradation (under 10%) over six months at room temperature. Its performance is highly dependent on cross-linking density.
Synergies
- Aqueous humectants
- Low-electrolyte botanical extracts
Conflicts
- Strong oxidizing agents
- High electrolyte concentrations
- Ionic surfactants
Safety
Safety Profile
While the parent Poloxamer 407 is well-established as safe, this specific derivative is primarily utilized in advanced K-beauty formulations and lacks a formal CIR monograph, though it is unrestricted in the EU.
