The main difference between potassium and sodium soaps is consistency — usually, potassium makes a softer, more water-soluble soap than sodium.

What is potassium carbonate used for in soap?
Potassium carbonate’s usefulness as a raw material for soap is that instead of burning alkalis and then converting fatty acids to soap, the fats are neutralized by both the sodium and potassium.
Why is potassium hydroxide used for liquid soap?
Because soap is the product of the reaction between fatty acids and an alkali. There are other alkalis that can be and are used, such as potassium hydroxide. Potassium hydroxide produces a soft soap and is normally only used to make a liquid soap.
Why potassium soap is more soluble than sodium soap?
Both sodium and potassium are alkali metals. The relatively high concentration of salt (sodium chloride) in seawater lowers the solubility of soaps made with sodium hydroxide, due to the salting out effect. Potassium soaps are more soluble in seawater than sodium soaps and so are more effective with seawater.
Which is better potassium hydroxide or sodium hydroxide?
But their differences actually start all the way down at the molecular level. Potassium hydroxide is slightly smaller than sodium hydroxide which means it cuts through oil molecules faster than sodium hydroxide. This makes potassium hydroxide a great choice for soaps that need to remove caked-on oil.
How do you make soap from ashes?
- Step 1: Gather Ashes. To produce a good soap, you need hardwood ashes that have been burnt throughout.
- Step 2: Make Lye. There are two methods you can use to make lye from hardwood ashes.
- Step 3: Concentrating the Lye.
- Step 4: Add Your Fat.
- Step 5: Pour Into Molds.
- Using Salt to Make Harder Soap.
How do you make liquid soap from ashes?
Heat the lye water
Pour a half gallon of the boiling water over the ashes. Once that has seeped down, pour another half gallon and wait 30 minutes before pouring another half gallon into your bucket. If you don’t have a gallon of brown lye water in your pot, pour another one half gallon in 30 minutes.
How does potassium soap differ from sodium soap?
The main difference between potassium and sodium soaps is consistency — usually, potassium makes a softer, more water-soluble soap than sodium.
Is potash the same as lye?
Sodium Hydroxide is more commonly known as lye or caustic soda where Potassium Hydroxide is known as potash. Both are used to change fats into soap in a process called saponification.
Can you use potassium hydroxide to make bar soap?
It forms a solid, opaque bar soap. Potassium hydroxide makes liquid soap, which is flowing, clear, or translucent.
Why are potassium soaps soluble in water?
This is because hard water contains calcium and magnesium ions. These ions form insoluble calcium and magnesium soaps respectively when sodium or potassium soaps are dissolved in hard water.
Why potassium hydroxide is used in saponification test?
The saponification value corresponds to the mass in mg of potassium hydroxide (KOH – commonly known as potash) needed to neutralize the free fatty acids and saponify the esters contained in a gram of material.
Is potassium laurate a soap?
Potassium Laurate is skin cleansing compound containing fatty acid potassium soap and glycerin.
Which soap contains potassium hydroxide?
KOH is noteworthy as the precursor to most soft and liquid soaps as well as numerous potassium-containing chemicals. Dry potassium hydroxide is produced by evaporating the water from liquid potassium hydroxide (LKOH).

What is the pH of potassium hydroxide?
The pH of a 0.05 M solution of Potassium Hydroxide is 12.7.
Which lye is best for soap making?
About this item
- Lye is also known as sodium hydroxide and caustic soda.
- Technical grade lye (non-food grade) is the lye of choice for soap making.
- Lye has traditionally been used as the main ingredient in soap making.
- Lye is used as a drain cleaner and clog remover.
What is lye used for?
Uses of Caustic Soda or Lye
Lye is used for soap making, candle making, homemade biodiesel, frosting glass, making several foods, and for chemistry experiments.
Can soap be made without lye?
In short the answer is no. Soap must be made using lye. Lye is the key ingredient in making soap. All products that are legally allowed to be called soap, must have gone through the process of saponification.
Can you still buy lye?
Craft stores carry lye for soapmaking. There is also food-grade sodium hydroxide, sold in some specialty cooking stores. You can find sodium hydroxide online. You can purchase it at Amazon as sodium hydroxide or lye, pure lye drain opener, caustic soda, and pure or food-grade sodium hydroxide.
What is soap ash?
Soda ash is a by-product in soap making created when lye comes into contact with carbon dioxide. It is a reaction that occurs inconsistently, and sometimes can cover the entire bar in large crystals. The reason it happens is somewhat of a mystery, but any soap maker can tell you it’s a pain to deal with.
What is lye made from?
Lye, or sodium hydroxide, is a chemical made from salt. Yep, ordinary salt. A system similar to electroplating is used to change the salt to lye.
