The saponification number or saponification value refers to the number of potassium hydroxide or sodium hydroxide required to saponify one gram of oil under specified conditions. This number is a value of the average molecular weight of all fatty acids present as triglycerides in the oil sample. The higher this value, the lower the average length of the fatty acids and the lighter the average molecular weight of the triglycerides. The opposite is also true. Practically, oils such as coconut and palm oil have a higher saponification value, and their fats or oils are considered more suitable for soap making.
Fats are generally classified as solid fats and liquid fats. These are glycerol esters. Typically, three different fatty acids are attached to a glycerol molecule. These are known as triglycerides. It is possible to add other fatty acids, therefore fats do not have fixed properties such as melting point or fracture point. For this reason, characteristic values such as iodine number, saponification number, acid number, peroxide number, and ester number of fats are investigated.
The saponification number is one of several characteristic values of oil and indicates how much potassium hydroxide is required to saponify 1 gram of oil.
In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests carried out in this context, there are also saponification number determination services.
