Sepimax Zen – Advanced Multifunctional Thickening and Stabilising Polymer

Sepimax Zen is a multifunctional polymer powder developed by Seppic, a renowned manufacturer of high-performance cosmetic ingredients. Designed for use in a wide range of cosmetic and personal care formulations, Sepimax Zen acts as a thickening, stabilising, and texturising agent. Its versatility, ease of use, and superior aesthetic performance make it a valuable addition to any formulator’s toolkit.

At its core, Sepimax Zen is a pre-neutralised powder polymer that effortlessly forms crystal-clear aqueous gels with a smooth, velvety, and elegant skin feel. These gels can range from fluid and sprayable to thick and luxurious, depending on usage level and formulation context. Because of its ready-to-use nature and broad compatibility with both water- and oil-based ingredients, Sepimax Zen is ideal for both seasoned formulators and those newer to cosmetic formulation.

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.

Ideal for Alcohol-Based Formulations

Sepimax Zen is exceptionally well-suited for use in hand sanitisers and hydroalcoholic gels. While Seppic indicates that a 3% concentration can support up to 70% alcohol, their own formulation for a 68% alcohol sanitising gel uses just 0.8% of the polymer.

Based on our own testing and experience, we recommend the following formulation for a simple, effective hand sanitiser:

Recommended Recipe:

• Isopropyl Alcohol (70%) – 952g

• Glycerine or Zemea Propanediol – 40g

• Sepimax Zen – 8g

Optional: Add 2–3 drops of essential oils such as tea tree, peppermint, or eucalyptus for added antimicrobial benefits and fragrance. Mix the essential oils into the alcohol and humectant phase before sprinkling in Sepimax Zen for best results.

This recipe yields a crystal-clear, stable hand sanitiser gel with excellent skin feel and minimal stickiness. The inclusion of glycerine or propanediol helps to counteract the drying effects of alcohol and leaves the skin feeling soft and moisturised.
