The effect of dimethyol urea (DMU) viscosity on a composite obtained from the reactive modification of DMU and epoxidized cotton seed oil ECSO was successfully investigated in this work. Some physico-chemical parameters of the Dimethyol urea obtained at different DMU viscosities (13.75 – 27.80 mpa.s) were evaluated. The Density, formaldehyde emission, melting point, refractive index were seen to increase with increasing DMU viscosity. DMU viscosity below 22.08 mpa.s was seen to produce DMU/ECSO blend soluble in water and beyond this value the composite became insoluble. The processing of DMU/ECSO composite by formulators for the development of an emulsion paint could therefore be suggested below the value.
