What can replace stearic acid in soap making?
Organic beeswax offers an all-natural substitute to stearic acid or e-wax as an emulsifier, although it is not as effective of an emulsifier, which may lead to a watery consistency in cosmetics and candles. Lecithin is another emulsifier that can be a substitute for stearic acid.
How do you mix stearic acid with oil?
As with the cetyl alcohol experiment, this one uses ratios: 3:1 through 1:6, with the first number being the stearic acid and the second being liquid olive oil. I used a single gram as my unit, so 3:1 is 3 grams stearic acid, 1 gram olive oil.
Which acid is used in soap?
Acids commonly added to soap include lemon juice (citric acid), vinegar (acetic acid), and yogurt (lactic acid). Adding these acids complicate the soap making process, because they react faster and more easily with NaOH or KOH than fatty acids can react.

Do I need stearic acid?

What can I use instead of stearic acid?
Heat to 70 to 800C and add sulphuric acid to remove the calcium as calcium sulphate. Pour off the liquid and allow it cool. The resulting greasey solid will have a melting point arround 690C similar to stearic acid and would be an acceptable alternative.
What does palmitic acid do for skin?
As a fatty acid, palmitic acid can act as an emollient. When applied to the skin by lotions, creams or bath oils, emollients can soften the skin and help it retain moisture by forming an oily, water blocking layer that slows the loss of water through the skin.
