What does SAP mean 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.
What is the SAP value of mango butter?
| Oil Sap Value | Lanolin 0.074 | Lard 0.138 | Macadamia Nut Oil 0.139 | Mango Butter 0.135 |

What is the SAP value of Crisco?
| Fat or Oil Lye (Sodium Hydroxide), NaOH Caustic Potash (Potassium Hydroxide), KOH | Crisco® Vegetable Shortening 0.1369 0.1928 | Emu Oil 0.1377 0.1939 | Evening Primrose Oil 0.1362 0.1918 | Flaxseed Oil 0.1358 0.1913 |

Which 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.
Why is SAP value important?
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 do you use values in SAP?
Once you have the SAP value for each oil in your formula, multiply the amount of each oil by its SAP value . This will give you the amount of caustic soda that you will need for each oil. Then add up all the amounts of caustic soda, and this will be the amount needed to turn ALL the oils into soap.
Can coconut oil be Saponified?
Saponification refers to the process by which a vegetable or plant oil is turned into soap! ... For instance, if you saponify coconut oil, the result is a very bubbly and glycerin-rich soap . Glycerin is an important product for its usefulness in helping retain moisture and prevent dry, itchy skin.
What is the SAP value of canola oil?
| Lipids SAP NAOH (oz.) | Calabash Oil 170 – 180 0.125 | Camelina Oil 185 – 197 0.136 | Candelilla Wax Pellets 43 – 65 0.039 | Canola Oil 173 0.123 |

What is a high saponification value?
A high saponification value indicates that the sample has a shorter fatty acid chain and a lower molecular weight . A low saponification value indicates that the sample has a longer fatty acid chain and a higher molecular weight.
How do you calculate saponification value of coconut oil?
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. (Acid number only measures the free acid). The combined acids are primarily esters formed by reaction with the neutral components present in the original tall oil.
How do you calculate soap?
- Calculate the volume of the mold in cubic inches.
- Multiply the volume of the mold by 0.4 to find the total amount of oils in the recipe. ...
- Enter that amount of oils into an online lye calculator to get the final recipe quantities.
What is soap value?
The saponification value is the amount of base required to saponify a fat sample . Soap makers formulate their recipes with a small deficit of lye to account for the unknown deviation of saponification value between their oil batch and laboratory averages.
What oil makes the hardest soap?
| Base Oil, Butter or Fat Soft, Hard or Brittle Recommended Usage | Coconut Oil – Learn more about coconut oil in soap making. Hard 15-50% | Palm Oil Hard 25-50% | Olive Oil – Learn more about olive oil in soap making. Soft 25-80% | Lard Hard 25-50% |

Which oil is best for soap?
Olive oil is generally the #1 oil in most soap makers’ recipes – and for good reason. Olive oil soaps are very moisturizing, make hard, white bars of soap (though high % olive oil soaps take a longer time to cure) and are exceptionally mild. But the lather from Castille soap is low and a bit slimy.
What oil makes soap bubbly?
- Coconut Oil – This is the number one soap making ingredient for creating lather with big, luxurious bubbles. ...
- Castor Oil – This is often used in a low percentage in soap recipes. ...
- Sunflower Oil – This oil helps to stabilize the lather so it doesn’t disappear right away.
