Saponification value, or SAP value, is an approximated "value" assigned to the fats and oils used in soap making. Because essential oils contain no lipids, they will not saponify. Consequently, they have no SAP value.
soponification value/number of an oil is defined as the milligram of KOH requird to sopanify fatty material present in 1gm of oil. sahil chhapola: for any enquiry about chemical engg. mail me at: sahilchhapola90@gmail.com
Well you see, everything has a value. Therefore, it does in fact have a value. Even a aluminum can has a value. Even a broken pot has a value. You see, nomatter if the value is nothing, or 1,000,000,000,000$ it still has a value in one way

Theories of value, or value theory, is a philosophy that examines what people value, how much they value it, and why. Value theory is often applied economically in an exchange of goods, but can also be applied ethically with regards to virtue and vice.
margarine has saponification value more then butter
Glycerin and soap are the bye-products of saponification. The saponification value of glycerine are values of the percentage of lye it takes to convert one unit of fat, oil or fatty acid into glycerin.
This value is between 4 and 10.
Saponification value is the amount of pure sodium hydroxide needed to saponified 100 grams of oil No. saponified castor oil is from 12.5 to 13 grams
Heat the flask on a steam bath.
To prevent formation of soap (by substitute the water with alcohol). But indeed KOH forms an ester with fatty acids. Explain a bit the role of alcohol please. Sometimes KOH is used to conjugate and Fatty acid. When lead to saponification and when to conjugation?

determination of saponification value (or "saponification number", also referred to as "sap" in short) represents the number of milligrams of potassium hydroxide or sodium hydroxide required to saponify 1g of fat under the conditions specified. It is a measure of the average molecular weight (or chain length) of all the fatty acids present. As most of the mass of a fat/triester is in the 3 fatty acids, it allows for comparison of the average fatty acid chain length. If more moles of base are required to saponify N grams of fat then there are more moles of the fat the chain lengths are relatively small, given the following relation: Number of moles = mass of oil/relative atomic mass Handmade soap makers who aim for bar soap use NaOH sap values which are derived from the saponification value calculated by laboratories (KOH sap value). To convert KOH values to NaOH values, divide the KOH values by the ratio of the molecular weights of KOH and NaOH (1.403). Standard methods for analysis are for example: ASTM D 94 (for petroleum) and DIN 51559. The calculated saponification value is not applicable to fats and oils containing high amounts of unsaponifiable material, free fatty acids (>0.1%), or mono- and diacylglycerols (>0.1%).
1gm fats or oils in the presence of water get hydrolyses ,obtained free fatty acids,to neutralise these acids,num of milligram of KOH required.....is safonification value.
