As an emulsifier, this product is mainly used in O/W silicone emulsion formulation. For example, it can emulsify Dimethicone, Phenylmethhicone,Hydroxyl silicone oil, Amido Dimethicone, Alkyl Dimethicone, etc, and achieve stable low-viscosity O/W silicone emulsions.


Mix this product and silicone oil and stir until uniform (System A). Add a small amount of water at one time into System A and stir. It can achieve the initial emulsion like cream. Then continue to add water. At this stage, the amount of water should be adjusted according to the formulation. Add water gradually and stir at the same time. The stable silicone emulsion can be achieved.

The recommended dosage is 2~10% (according to the total formulation amount).


The product is supplied in 50Kg plastic pails and 200Kg plastic pails.

Samples are available upon request in bottles.
