Manufacturing Process Phase A: Add Allantoin to water and heat to 40 °C. Stir until complete dissolution. Add Glycerin and Cosphaderm® Propanediol natural. While stirring add Cosphaderm® X 34. Stir until complete dissolution. Then add Aristoflex® AVC and stir until complete dissolution. Phase B: Prepare phase B and separately heat phase A and phase B to 80 °C. Add phase B to phase A while stirring.
Manufacturing Process Phase A: Combine all ingredients of phase A and stir until complete dissolution. Adjust the pH value to 5.5 +_ 0.05. Phase B: Prepare phase B in a separate beaker. Add phase B to phase A without stirring and pour mixture into spray flask. Specification Appearance: Two-phase system with oil phase on top of translucent water phase pH: 5.5 +_ 0.05 Stability: Microbiological stabil
