How is soap made in chemistry?
Soap making involves the hydrolysis of a triglyceride (fat or oil) using an alkaline solution usually lye, chemical name sodium hydroxide. Triglycerides are typically triesters consisting of 3 long-chain aliphatic carboxylic acid chains appended to a single glycerol molecule (see Equation 1).
How do you make a soap chemistry class?
- If you are starting with solid sodium chloride (rather than liquid), weigh 15 g of sodium chloride and put it in a 100-mL beaker.
- Add 50 mL of water and stir until dissolved.
- Heat the salt solution until it is almost boiling.
How do you make soap in organic chemistry?
How do you make soap step by step?

- Step 2: Mix the Water and Lye.
- Step 3: Mix the Oils with the Lye Water.
- Step 4: Bring the Soap Mix to Trace.
- Step 5: Add to the Mold.
- Step 6: Leave to Rest.
How do you make soap for beginners?
- Mix water and lye, set aside to cool.
- Melt oils, set aside to cool.
- Blend lye water and oils to form a soap “batter”

What are the 3 main ingredients in soap?
If you only rinse them with water, they still feel greasy. However, if you add soap to the water, the grease washes away, and the result is clean dishes. There are 3 key ingredients in soap: oil or fat, lye and water.
What 3 ingredients are needed to make soap?
- Soap Base. With a soap base, you don’t need to start the process of soap making from scratch or have to deal with dangerous lye solution – metal hydroxide that needs to be handled very carefully.
- Essential Oils.
- Natural Ingredients.
What is soap chemical reaction?
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.
What is the soap formula?
The formula for soap is C17H35COONa.
Which chemical is used for making soap?
Sodium hydroxide is employed as the saponification alkali for most soap now produced. Soap may also be manufactured with potassium hydroxide (caustic potash) as the alkali. Potassium soaps are more soluble in water than sodium soaps; in concentrated form, they are called soft soap.
What is the main ingredient in soap?
Soap is the Result of Saponification At the heart of all cold process soap recipes are two main ingredients: oil and lye, also known by its chemical name sodium hydroxide. Your soap-making recipe will, through a simple but controlled process, chemically bond these two ingredients into a new compound – soap!
What is the science behind soap?
But soap molecules have two different ends to them. One end is attracted to water molecules – this is called hydrophilic – and the other end loves oil and fat molecules – this is called hydrophobic. Soap is able to bind to the oils on our hands, and then mix with the water to wash all the germs away.
What is the easiest way to make soap?
Melt and pour soaps are the best way to make homemade soaps without using lye. And it’s real easy to do. You simply melt your soap base, add the essential oils and other additives you want like herbs or flowers, pour into the soap molds and let it cure. Melt and pour soaps are perfect beginner soap recipes.
What is the process of making hot soap?
- What you will need.
- Step 1: Measure and prepare.
- Step 2: Melt your oils.
- Step 3: Mix up your lye solution.
- Step 4: Combine melted and liquid oils.
- Step 4: Time to Make the Soap!
- Step 4: Cook it!
- Step 5: Craft your masterpiece.
Is soap easy to make?
Making soap is really very easy. All you have to do is to mix a lye solution by mixing the lye with water. (Pour the lye into the water and not the other way around.
How hard is it to make soap?
Soap making can be very simple or you can make it as complicated as you like. First, the beauty of making your own is that you can make it with the ingredients that you choose and the fragrances that you like. And adjustments aren’t hard but do take some practice.
How do you make soap without heat?
What makes a good soap?
A good bar soap balances hardness, lather quality, and moisturizing. Doing all three is tricky. Each of these properties comes from different fatty acids in the vegetable oils we use. Different oils make different contributions.
Can soap be made without lye?
NO, chemically-speaking, soap itself cannot be made without lye. Soap is made by blending oils (like olive oil or coconut oil), a liquid (water, goat’s milk, etc.), and an alkali (lye). Lye is needed to convert oils into soap.
What is natural soap made of?
So to answer the original question in a short and sweet summary, natural soap is made from natural oils mixed with lye, fragranced with essential oils and coloured using only natural ingredients such as turmeric, spinach and alkanet root.
How do you make soap bases without chemicals?
- 1 cup baking soda.
- 2-5 tablespoons water.
- 10 drops eucalyptus essential oil.
- 10 drops peppermint essential oil.
- 10 drops lavender essential oil.
- Soap colorant (optional)
- Silicone mold.
What is the pH of soap?
Results: Majority of the soaps have a pH within the range of 9-10. Majority of the shampoos have a pH within the range of 6-7.
What acid is used in soap?
Today, the process of making soap most commonly involves reacting an organic acid with an alkaline chemicals like potassium hydroxide or sodium hydroxide. Industrially, the caustic soda base used most often is sodium hydroxide, which is also called lye.
How does soap experiment work?
- Fill one bowl with water. Fill the second bowl with a small, soapy mixture.
- Add pepper (acting as germs) on top of the bowl filled with just water.
- Dip your finger in the soapy mixture, then dip your finger into the water bowl with pepper in it. Watch what happens!
