Dusting Analysis
While it is a film-former, there is no specific data indicating Ammonium Shellacate is commonly dusted in typical cosmetic applications or has established dusting thresholds.
The Formula
Formulation
Stability
An aqueous solution requiring a pH above 7.0 for stability, as it precipitates below pH 6.0 when the resin reverts to its acid form.
Conflicts
- Acidic ingredients (causes precipitation)
- Cationic surfactants
- Strong electrolytes
Safety
Safety Profile
Ammonium Shellacate itself has not been CIR-reviewed, but its components, Ammonium Hydroxide and Shellac, are considered safe for cosmetic and food uses respectively when properly formulated.
