(AOAC 920.160) In duplicate about 2g of the oil sample is added to a flask with 30ml of ethanolic KOH and is then attached to a condenser for 30 minutes to ensure the sample is fully dissolved. After sample has cooled 1ml of phenolphthalein is added and titrated with 0.5 M HCl until a pink endpoint has reached.

Saponification values are highly significant in the making of soap. It is important that the sap value is just right too high and the soap might contain too much alkali even though there is sufficient soapiness that it would react with skin whilst a sap value too small -the fatty acid salts will not be sufficient enough to remove or saponify the fat or oil and less soapiness.
The saponification value of an oil is the amount of alkali required to saponify a definite quantity of the sample.
It is expressed as the number of milligrams of potassium hydroxide (KOH) required to neutralize 1 gram of the sample.
You can find the saponification values of any oil, fat or butter through various websites with SAP charts. If you need to figure lye/water solution for oils/fats/butters to create soap, the formula is a simple algebra eqaution as follows: (x) . (y) = z (x) / (y) = z (x) - (y) = z More specifically : ( Oil Weight ) x ( SAP Value of Oil) = Amount of Lye Then.. ( Amount of Lye) / ( 0.3) = Total Weight of Lye/water solution Then.. (Total of Lye/Water Solution) - ( Amount of Lye) = Amount of water
The significance of saponification number is that it measures the exact value of potassium hydrate in milligrams. This will measure unbonded and bonded acids in fat.
Both saponification value and number is same
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.
Saponification is the process of producing soap. Refluxing is done in saponification to distill and remove fat droplets in order to complete the process.
Saponification is the reaction between triesters and alcohol.Mineral oil is composed of paraffins and alkanes ,it does'nt contain ester group hence it does not undergo saponification
Saponification
Insoluble soaps are not likely to exist, they won't work when not IN water. For more you can trust on this: his process is called saponification: fat + sodium hydroxide -> Sodium salts of fatty acid (Soap) + glycerol
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, 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.
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.

Ethanol is added to hasten saponification.

Saponification is not applied to pure stearic acid; stearic acid esters are used.
