GB/T 6369-2008 《Surface active agents - Determination of emulsifying power - Colorimetric method》 Related products

This standard specifies a Colorimetry method for measuring the emulsification force of surfactants. By mixing an emulsifying agent with a colored oil and oscillating it to form an emulsion, the oil in the emulsification layer is extracted with a solvent, the optical density value of the extract is determined, and the emulsification force is calculated from the working Linear dispersion. Suitable for the evaluation of the emulsification capacity of the effluent oil treatment agent.
