Product Overview

Surfactant Free

Surfactant Free particles are specially made for applications that cannot tolerate the presence of surfactant. Our surfactant free particles are sold as both unmodified and carboxylated. The products listed below with a diameter larger than 0.7 um are essentially surfactant-free. For particles smaller than 0.7 um, a small percentage of surfactant is present (<0.05%). For these particles, the smaller the diameter, the higher the percentage of surfactant.
