TRO
Many here suggest TRO (sulphonated castor oil) or castor oil along with Pine oil for making White Phenyl. I really do not know why. Phenyl is based on Pine oil and is an oil-in-water emulsion. The oil needs to be well emulsified and added slowly into RO treated water. Choice of emulsifier does the trick. Synthetic non-ionic thickeners are used to increase the viscosity. The ideal end pH is between 5.5 and 6.5 and the emulsion will be stable for many months without any separation.
