Synthrapol is an industrial strength, pH neutral, liquid detergent used as a prewash and afterwash for dyed or painted fabrics and as a wetting agent for fabric dyes and paints. Synthrapol has the unique property of keeping loose dye suspended during washing, thus preventing backstaining while aiding in the removal of excess color.
