FORMULATIONS

Phase A: Combine all ingredients and dissolve Phase A at 40°C.
Phase B: Add phase B to phase A and adjust the pH to 5.0 – 5.5.
Phase C: Add phase C to phase A/B under soft stirring.
Phase D: Dissolve Cosphaderm® Magnolia Extract 98 in Cosphaderm® Propanediol natural and Cosphaderm® TOM. Add phase D to phase A/B/C under stirring.
Adjust the pH to 5.0 ± 0.05.

Appearance: Yellowish, translucent gel
pH: 5.0 ± 0.05
Stability: No separation after centrifugation (4000 rpm, 30 min), stable for 3 months at room temperature and 40 °C
Microbiological stability: proven

Phase A: Combine all ingredients of phase A and stir until everything is dissolved.
Phase B: Slowly add phase B to phase A under stirring. Stir until complete dissolution.
Adjust pH to 5.5 ± 0.05 and heat phase A and B to 70 °C.
Phase C: Combine all ingredients and heat phase C to 70 °C. Add then phase C to phase A and B under strong stirring and homogenise the formulation.
Adjust pH to 5.2 ± 0.05.

Appearance: Slightly yellowish gel cream
pH: 5.2 ± 0.05
Stability: No separation after centrifugation (4000 rpm, 30 min), stable for 3 months at room temperature and 40 °C
Microbiological stability: proven

Phase A: Combine all ingredients of phase A and raise the pH to 11 under stirring to dissolve cinnamic acid. Afterwards, adjust the pH to 5.5 ± 0.05 by adding Citric Acid.
Phase B: Add phase B to phase A and stir until everything is completely dissolved.
Heat phase A+B to 60 °C and add phase C under strong stirring.
Phase D: Add phase D to phase A+B below 40 °C.
Adjust the pH to 5.5 ± 0.05.

Appearance: Transparent, yellow gel
pH: 5.5 ± 0.05
Stability: No separation after centrifugation (4000 rpm, 30 min), stable for 3 months at room temperature and 40 °C
