Ceteareth-20 (ELOTANT CSAE 120) is the highest-ethoxylation member of the Ceteareth series in your catalog — and that higher ethoxylation count translates directly into stronger hydrophilicity, more robust O/W emulsification, and a greater capacity to thicken and stabilize formulations compared to its Ceteareth-10 and Ceteareth-12 counterparts. It is one of the most widely used and well-characterized emulsifiers in the cosmetic industry, trusted by formulators globally for its reliability, versatility, and consistent performance across a broad range of formulation systems.
Available in convenient white to creamy flakes, it weighs accurately, handles cleanly without dust, and melts smoothly into the oil phase at standard processing temperatures. Once in the formulation, it reduces interfacial tension between oil and water phases, builds a stable emulsion network, and contributes meaningful viscosity and body to the finished product — giving creams and lotions that rich, luxurious consistency that feels premium in the hand and on the skin. In hair conditioners and styling products, it helps distribute conditioning actives evenly while contributing to the creamy, spreadable texture that makes a conditioner feel genuinely nourishing. A cornerstone emulsifier for professional cosmetic formulation.

Formulation Tips
Add to the oil phase and heat to 70–75°C alongside other wax-phase ingredients — the flake form melts readily and incorporates cleanly. For maximum emulsion stability, combine with Cetearyl Alcohol as a co-emulsifier to build a robust lamellar emulsifier system — this is the classic Ceteareth-20 / Cetearyl Alcohol combination used in countless professional cream formulations. Ceteareth-20 can also be used alongside Ceteareth-10 or Ceteareth-12 in blended emulsifier systems to fine-tune HLB, texture, and viscosity. Compatible with most cosmetic actives, humectants, and preservative systems across a wide pH range.
