Remarks1.*Acid number is determined at time of production. Prolonged storage will result in slight oxidation, which will  produce an increase in acid number. The smaller particle size powder is more susceptible to surface oxidation. Acid number is expressed as an absolute value and is the mg of KOH required to neutralize the acid in a one-gram sample;
