Ceteareth-10 (Bris CSA10) is the kind of emulsifier that makes formulation feel effortless — a reliable, well-behaved nonionic surfactant derived from ethoxylated cetyl and stearyl alcohols that bridges the gap between oil and water phases with quiet efficiency. At the right concentration, it creates stable, uniform oil-in-water emulsions that stay together beautifully over time, without the separation, graininess, or instability that can plague under-emulsified formulations.
Its white to creamy solid form melts cleanly into the oil phase, and its moderate HLB value makes it particularly effective in O/W systems where a smooth, creamy texture and good skin feel are priorities. In creams and lotions, it contributes to that rich, even consistency that spreads effortlessly and absorbs cleanly. In hair conditioners, it helps distribute conditioning agents uniformly through the formulation. For formulators who need a dependable, versatile emulsifier that works across a wide range of cosmetic systems, Ceteareth-10 is a solid, proven choice.

Formulation Tips
Add to the oil phase and heat to 70–75°C alongside other oil-phase waxes and emollients before combining with the heated water phase. For best emulsion stability, combine with a co-emulsifier such as Cetearyl Alcohol or GMS to build a more robust emulsifier system. Adjust concentration based on the oil load of the formulation — higher oil content typically requires higher emulsifier levels. Compatible with most cosmetic actives, humectants, and preservative systems.
