Concentrated Liquid Polymer for Clean Beauty

Winner of Ringier Technology Innovation Awards 2021 in China, SEPIPLUS™ K is a liquid polymer produced by inverse emulsion polymerization. In concentrated form, the transport of water can be reduced in comparison to standard (non-concentrated) grades.

To remember
  1. A solvent, preservative and EO (ethylene oxide)-free polymer, which is suitable for clean cosmetics.
  2. A concentrated liquid polymer which brings high performance in formulation.
  3. Silicone-like gliding skin feel


SEPIPLUS™ K is a rheological modifier which combines clean, performing and sensorial assets.

SEPIPLUS™ K is solvent, preservative and EO (ethylene oxide)-free, which is suitable for clean cosmetics. It provides high performance in terms of thickening, oil stabilizing and resistance to electrolytes. It imparts a silicone-like gliding skin feel and adds a graceful touch to the formulation.
