Dusting Analysis
There is no available data to suggest that CYCLO(PROLYLPROLINE) is commonly used at concentrations that would be considered 'dusting' or a red flag in cosmetic formulations.
The Formula
Formulation
Stability
Research indicates an optimal pH of approximately 10.7 at 55 °C for the *synthesis* of cyclo-Pro-Pro, with no formation observed under neutral or acidic conditions. However, this observation relates to its creation, not its stability within a finished cosmetic product. Specific data on the optimal pH range for the stability of CYCLO(PROLYLPROLINE) in cosmetic formulations is not available.
Safety
Safety Profile
No dedicated safety assessments by major regulatory bodies such as CIR, SCCS, or FDA for CYCLO(PROLYLPROLINE) specifically for cosmetic applications have been identified. While general information on other cyclic dipeptides or cosmetic ingredients exists, it cannot be directly extrapolated to this particular compound, leaving its specific cosmetic safety profile unestablished.
