Science
Mechanism of Action
Forms a continuous, hydrophobic film upon application that creates a protective barrier on the skin surface. The butylated modification reduces hydrogen bonding between polymer chains, allowing the ingredient to dissolve in oils and organic solvents while maintaining film integrity against water and sweat.

Dusting Analysis
Not typically used for dusting purposes as this ingredient functions specifically as a film-forming polymer rather than a marketing additive
The Formula
Formulation
Stability
Maintains optimal stability in slightly acidic conditions. Alkaline environments above pH 8.5 significantly accelerate formaldehyde release. Heat exposure above 150°C can cause hazardous decomposition.
Conflicts
- Strong oxidizing agents
- Strongly alkaline ingredients
- High heat applications
Safety
Safety Profile
Classified as formaldehyde-releasing agent with approximately 0.2% free formaldehyde content. Under regulatory scrutiny in some jurisdictions due to potential formaldehyde exposure concerns.
