Alcohol esters of soybean oil may be substituted directly for soybean oil in news, sheet-fed, cold-set and business forms inks to obtain the minimum concentration standard.  The minimum soybean oil concentration for heat-set inks increased to 15% (by weight) when alcohol esters of soybean oil replace soybean oil in this formulation.
