Suractants & Emulsifiers


(2000)

My name is Horacio form Brownsville, Texas. I used to fabricate an anti-rust product that sold well in Mexico's coastlines, but 3 years ago I cancelled production since one of my raw material production was cancelled by it's company. This product was a Polyol that served as a emulsifier and surfactant and could stand acid mixtures. Who can recommend me a good surfactant ?

thanks

Depends on the acids:

For phosphoric and HCl acids Alcohol ethoxylates are suitable. For sulphuric I would suggest Dowfax 2A1 or 3B2.
