  2. Step 2: Design Your Soap Recipe.
  3. Step 3: Measure Your Olive Oil/Heat Olive Oil.
  4. Step 4: Measure Your Lye.
  5. Step 5: Add Essential Oils.
  6. Step 6: Stir the Solution (Saponification Process)
  7. Step 7: Pour Soap Into Molds.

Also Know, what is the chemical reaction for making soap? Saponification is the name of the chemical reaction that produces soap. In the process, animal or vegetable fat is converted into soap (a fatty acid) and alcohol. The reaction requires a solution of an alkali (e.g., sodium hydroxide or potassium hydroxide) in water and also heat.

In this regard, how can you make soap in laboratory?

Soap is made in the laboratory by the process of Saponification. The process involves reacting a vegetable oil like palm oil or olive oil with an alkali like Sodium Hydroxide. This reaction is exothermic in nature, liberating heat during the reaction.

How are soaps prepared?

Soap is prepared by hydrolyzing a fat under alkaline (basic) conditions. The reaction is called saponification, and produces one molecule of glycerin and three molecules of soap, for each molecule of fat taken.

What happens when you add HCL to soap?

Treatrment of a soap solution with dilute hydrochloric acid produces a mixture of fatty acids. Fatty acids are long-chain carboxylic acids (C10 to C18 ) which may be saturated or unsaturated .

How do I know if my soap is safe?

An extremely common recommendation I found as a method of checking the soap pH is to touch a bar of soap to your tongue. If touching the bar of soap to your tongue zaps similar to touching your tongue to a battery, it indicates a soap is lye heavy.

Why is nacl added in saponification?

Why is common salt added after the process of saponification? When we add salt which is sodium chloride, it gets ionised in water and the sodium ions causes the sodium ions of soap to combine with the fatty acid ions and separate as solid soap. This helps in complete removal of soap from the reaction mixture.

How does soap remove dirt?


When greasy dirt or oil is mixed with soapy water, the soap molecules arrange themselves into tiny clusters called micelles. The water-loving (hydrophilic) part of the soap molecules sticks to the water and points outwards, forming the outer surface of the micelle.

Is soap an ester?

Soaps. Soaps are made from naturally occurring animal fats and vegetable oils. The animal fats and vegetable oils are esters of the alcohol, propane-1,2,3-triol (glycerol) CH2OHCHOHCH2OH and long chain carboxylic acids (often known as fatty acids) RCO2H, where the alkyl groups contain between 7 and 21 carbon atoms.

Is Lye an acid or base?

The assassins typically use sodium hydroxide or potassium hydroxide, strong bases commonly known as lye. (The Times story misidentified their reagent of choice as an acid.) Heated to 300 degrees, a lye solution can turn a body into tan liquid with the consistency of mineral oil in just three hours.

What is the purpose of making soap?

Soap is a surface active agent, or surfactant, according to the Essential Chemical Industry, help to reduce the surface tension of the water so it can spread and wet the surface and speed up the cleaning process. Some people describe this as soap making "water wetter."

What are the chemicals used in soap?


Sodium Hydroxide (Lye) is the chemical used in soap making. There are other ingredients used such as: Olive Oil, Coconut oil, Castor oil, Distilled water. Other ingredients to add color that can be used are called Micas.

What does adding salt to soap do?

Adding salt does not result in an overall harder finished bar of soap, but it does make the bar get harder faster. By adding a small amount of salt to your recipe, you can get your bars out of the mold faster and they're actually easier to remove.

Why does nacl precipitate soap?

Soaps are sodium salts of fatty acids. Addition of sodium chloride reduces the solubility of the soap salts. The soaps precipitate due to a combination of common ion effect and increased ionic strength. In the presence of excess sodium ions the solubility of soap salts is reduced, making the soap less effective.

How do you purify soap?

These impurities are removed by boiling the crude soap curds in water and re-precipitating the soap with salt. After the purification process is repeated several times, the soap may be used as an inexpensive industrial cleanser. Sand or pumice may be added to produce a scouring soap.

What is the other name for saponification?

The other name for is saponification is soaps.
Saponification is a process by which triglycerides are reacted with sodium or potassium hydroxide (lye) to produce glycerol and a fatty acid salt, called "soap."

Why is my homemade soap brittle?


Soap with a dry, crumbly texture could be caused by too much lye in your recipe. If your soap has a crumbly texture, ensure it is not lye heavy. If the pH is safe to use, the crumbly texture could also be caused by soaping with cool temperatures. Soaping cool (100 °F or below) can increase the chance of soda ash.

Does saponification value affect the quality of soap?

Saponification value is also used in checking adulteration. The larger the saponification number, the better the soap making ability of the oil [3]. Saponification value for unrefined vegetable oils may also be affected by the compounds in the nonsaponifiable fraction.

What is the structure of soap?

A soap molecule consists of a polar ionic hydrophilic (water "loving") end, which is shown in blue in the structure above, and a non-polar hydrophobic (water "hating") end, which is the hydrocarbon chain shown in red above.
