How to use
- Select an oil from list of oils in the center.
- Soap Qualities
- The approximate percentage of the fatty acids that
contributes to that quality in the soap.
- The Iodine absorbtion value for the oil.
- The INS value for the oil.
- Fatty Acids The
approximate percentage of each fatty acid in the oil.
- SAP Value The
saponification factor for the oil.
- With an oil selected, click one of the
Plus buttons to add the oil to the Oil/Fat recipe list on the
right. Selecting another oil from the list and clicking the same Plus button again will replace the first oil
with the second.
- Design your soap.
- Select each oil in your recipe and click a Plus button to place it on the Oil/Fat recipe
list.
- Enter the percent of each oil in the % column. The total per cent must equal
100%
- Select either NaOH (Lye) or KOH (Potassium Hydroxide)
- Total Oil Weight: Select
the unit of weight you will use: Pounds, Ounces or Grams. Then
enter the total weight of all the oils you will use. (One pound
of oils will produce about 1.37 pounds of soap, plus or minus,
depending on oils, amount of water and additives.
- (Top right) Enter the per cent of water in the recipe.
- (Top right) Enter the per cent of super fat.
- Fragrance Ratio:
(Optional) Enter the fragrance ratio.
- Click the Compute Recipe
button on the bottom. If there are no error messages, the results of
your recipe will be displayed.
- If there are error messages, make the correction and
click Compute Recipe again.
- Note: If the ratio of Lye to Water in your recipe is
too high to be generally considered safe, a warning will display.
However, the calculation will complete.
- View the results
- The combined column
under Soap Qualities and Fatty Acids now displays computed values based on
the percentages of each oil and the recipe's combined oil qualities.
- At the bottom of the screen are the weights of your
recipe ingredients. Values are given in Pounds, Ounces and Grams.
- If you entered a Fragrance Ratio, the amount of
fragrance will display.
- Save your recipe
- Your recipe can be saved as a Cookie on your Computer.

Notes:
Every reasonable attempt has been made to provide accurate
calculations.
SAP values have been obtained from various sources on the web.
It is recommended that the superfat value be set to at least several
percent in the Soap Formulator - the default value is 5%.
Iodine values
are averages of those available from various sources and are meant to
be a general
indicator for the hardness that the oil or fat will contribute to the
soap. A lower iodine value will produce a harder soap. Some
Iodine values are estimated.
If you'd like an oil added to the calculator, please provide the following with your request. Thank you.
- Name of the oil (alternate names would also be helpful)
- SAP (Na or KOH, specify which)
- Fatty Acid profile: per cent of lauric, linoleic, linolenic,
myristic, oleic, palmitic, ricinoleic, stearic.
- Iodine value
- INS (if available, if not it will be estimated from the iodine and
SAP values)
