How is SAP value calculated?
Saponification Value = (A – B) x N x 56.1 W This method is used to determine the total acid content, both free and combined, of tall oil. … The saponification value is therefore a measure of tall oil quality. It is determined by measuring the alkali required to saponify the combined acids and neutralize the free acids.

What is high saponification value?
The higher the saponification value, the lower the fatty acids average length, the lighter the mean molecular weight of triglycerides and vice-versa. Practically, fats or oils with high saponification value (such as coconut and palm oil) are more suitable for soap making.
How much lye should I use?
If using more liquid oils in your soap, though, superfatting over 10% is probably going to result in a soft bar of soap that isn’t as cleansing. The default in the Soapcalc lye calculator is 5%. I think 5-8% is a good range to play with, depending on what type of soap you are making.What is lye discount?
An average superfat is usually between 1–7%. This means 1–7% of oils in the recipe are “free-floating” in the bar and were not turned into soap. A superfat is also referred to as a “lye discount.” This is because in order to turn fewer oils into soap, you reduce the amount of lye in the recipe.
What is the SAP value of rice bran oil?▶ Saponification value It helps to detect the presence of other oils/ fats. The saponification value of rice bran oil should be between 180 and 195.
Article first time published onWhich oils Saponify faster?
More saturated oils (like coconut and palm oils which are solid at room temperature) tend to saponify more quickly than less saturated oils such as olive oil.
What is the saponification value of ghee?
The mean saponification value for local ghee ranged from 156.19 ± 0.06 to 245.53 ± 0.19. L2, L4–L7, and L10–L14 samples’ mean saponification values were below 225 (Table 2). Enriching ghee with animal body fat and vegetable oil somewhat changed the saponification value [31].

Does shea butter have Saponify?

Which oils are not Saponifiable?
Baby oil, liquid paraffin and liquid petroleum are the mineral oils and they are not saponifiable. Explanation: The saponification of vegetable oil and animal oil is very high.
What is acetyl value?
Definition of acetyl value : a measure of the free hydroxyl groups in a substance (as a fat or oil) as determined by acetylation, being the number of milligrams of potassium hydroxide required for neutralization of the acetic acid formed by hydrolysis of one gram of the acetylated substance.
What is SAP in soap making?
These saponification values are also known as a “SAP value.” This SAP value equates to the number of milligrams of KOH (potassium hydroxide) it takes to convert or “saponify” a fat into soap. … It is the average molecular weight of the amount of fatty acids present.
Why is acid value important?
Acid value is taken as an important indicator of oxidation of oil. The acid value is the number of mg of potassium hydroxide required to neutralize the free acid in 1 g of the substance l. Acid base titration techniques in non-aqueous solvents mostly used for determination of acid value in oil.
What is the acetyl number?
[ə′sed·əl ‚nəm·bər] (analytical chemistry) A measure of free hydroxyl groups in fats or oils determined by the amount of potassium hydroxide used to neutralize the acetic acid formed by saponification of acetylated fat or oil.
What is acidic oil value?
The acid value is defined as the number of milligrams of Potassium hydroxide required to neutralize the free fatty acids present in one gram of fat. It is a relative measure of rancidity as free fatty acids are normally formed during decomposition of triglycerides.
How do you know if saponification is complete?
The zap test is when you stick a bar of soap to your tongue. If it zaps you like a 9-volt battery, your soap is still not saponfied. If it doesn’t, it is probably done with the process. Again, saponification takes about 24-48 hours.

What is the saponification value of vegetable oil?
Easter and Saponification values were ranged between 14.92-20.89 and 19.41-21.54 mg KOH/g oil in fresh oils respectively and between 16.11-21.60 and 21.15-22.44 mg KOH/g oil in frying oils respectively furthermore, Peroxide values ranged from 12.5 to 55 Meq/Kg in fresh oils and from 37.5 to 150 in frying oils were to …
What is Superfat in soap making?
Superfatting is the process of using less lye (or more fat) than industry standards so that there’s some leftover oil in the soap that’s not bound to lye. This leaves behind more unsaponified fat, providing more moisture in the soap. Every oil requires a different amount of lye to turn it into soap.
How do you make a 50 lye solution?
For example, if your recipe calls for 5 ounces of lye and 10 ounces of water, you would measure out 10 ounces of a 50:50 solution. (10 ounces of 50:50 solution would consist of 5 ounces of lye and 5 ounces of water.)
What percentage of soap is Superfat?
Oil that’s not turned into soap by the sodium hydroxide lye is called the “superfat.” An average superfat is anywhere from about 1-7%. The higher the superfat, the more “free-floating” oils in the soap. The terms “superfat” and “lye discount” can be used interchangeably.

What percentage of soap is lye?
Most recipes and tutorials here on Modern Soapmaking use a 33% lye solution, as it’s typically a manageable water discount during the soapmaking process, but also hardens up a little quicker to get the soap out of the mold! A strong water discount is typically referred to as a 40% lye solution.
