Formulation Tips & Usage Recommendations

Please note: The following usage guidelines are based on extensive hands-on experience with Sepimax Zen and are not official manufacturer recommendations.

1. As a Thickener and Stabiliser in Creams
   Use Sepimax Zen at 0.3–0.4% to provide effective thickening and stabilisation in emulsions. For optimal performance, add it to the heated water phase:

• Heat your water phase (including Sepimax Zen and any other water-phase ingredients) to approximately 80°C.

• While maintaining this temperature, sprinkle Sepimax Zen over the water surface and immediately blend with a stick blender on high speed to disperse.

• Once fully hydrated and dispersed, add the heated oil phase to form the emulsion.

• Works beautifully with emulsifiers like Olivem 1000 and Montanov 68 for stable, elegant creams and lotions.

2. As a Gelling Agent
   To create clear, stable gels:

• Use Sepimax Zen at 1.5% to 3% concentration.

• Sprinkle it onto the surface of cold water without stirring.

• Allow it to hydrate for 6–8 hours (overnight is ideal).

• Once fully hydrated, gently stir with a spatula or similar implement to obtain a clear, bubble-free gel.
