Science
Mechanism of Action
Forms a continuous, hydrophobic film upon application that adheres strongly to skin and hair. The polymer's molecular structure creates a flexible barrier that resists water penetration while maintaining breathability, simultaneously binding other active ingredients to enhance their staying power.
Research
Clinical Evidence
High confidence4%
Key findings
- 01 Demonstrated significant increase in rub-resistance and water-resistance in topical film-forming formulations
- 02 Evaluated in human repeat insult patch tests and found to be neither a primary irritant, sensitizer, nor photosensitizer
Transparency
Dusting Analysis
Not typically subject to dusting as it serves a specific film-forming function that requires meaningful concentrations to be effective
The Formula
Formulation
Stability
Inherently alcohol-soluble but requires neutralization with bases like Aminomethyl Propanol or Triethanolamine (10-100% neutralization) to achieve water solubility and optimize film flexibility
Synergies
- Aminomethyl Propanol (AMP)
- Triethanolamine (TEA)
- Other film-forming agents
Conflicts
- Unlined tinplated containers
- Highly cationic systems
Safety
Safety Profile
Large molecular weight prevents skin penetration, making systemic toxicity unlikely. Must be used in neutralized form for optimal safety profile.
