Soap requires two major raw materials: fat and alkali. The alkali most commonly used today is sodium hydroxide. Potassium hydroxide can also be used. Potassium-based soap creates a more water-soluble product than sodium-based soap, and so it is called “soft soap.”
Consequently, what is soap made out of?
Today, soaps are made from fats and oils that react with lye (sodium hydroxide). Solid fats like coconut oil, palm oil, tallow (rendered beef fat), or lard (rendered pork fat), are used to form bars of soap that stay hard and resist dissolving in the water left in the soap dish.
What chemical is used to make soap?
Today, the term alkali describes a substance that chemically is a base (the opposite of an acid) and that reacts with and neutralizes an acid. The common alkalis used in soapmaking are sodium hydroxide (NaOH), also called caustic soda; and potassium hydroxide (KOH), also called caustic potash.
What are the ingredients of Dove soap?

What kind of oil is in Murphy’s Oil Soap?
Commercials for the product state that the product is ideal for cleaning wood surfaces. The other constituents of Murphy Oil Soap are sodium EDTA, propylene glycol, fragrance, surfactants, and water. Murphy Oil Soap is commonly used to clean and polish horse tack, such as bridles and saddles.
What is soap making?
COLD PROCESS: Cold Process soapmaking is the act of mixing fixed oils (common oils include Olive, Coconut and Palm) with an alkali (Sodium Hydroxide or Lye). The result is a chemical process called saponification, where the composition of the oils change with the help of the lye to create a bar of soap.
What is the use of saponification process?
Soaps are sodium or potassium salts of long chain fatty acids. When triglycerides in fat/oil react with aqueous NaOH or KOH, they are converted into soap and glycerol. This is called alkaline hydrolysis of esters. Since this reaction leads to the formation of soap, it is called the Saponification process.
How the plastic is made?
How plastics are made. Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used.
What chemicals are used to make detergents?
Other Chemicals. Chemicals, such as sulfur trioxide, sulfuric acid and ethylene oxide, are used to produce the water-loving end of the surfactant molecule.
What do you mean by saponification?
In simple terms, saponification is the name for a chemical reaction between an acid and a base to form a salt. When you make soap using the cold process soap making method, you mix an oil or fat (which is your acid) with Lye (which is your base) to form soap (which is a salt).
Where does lye soap come from?
A lye is a metal hydroxide traditionally obtained by leaching ashes (containing largely potassium carbonate or “potash”), or a strong alkali which is highly soluble in water producing caustic basic solutions.
Are detergents soluble in water?
These substances are usually alkylbenzenesulfonates, a family of compounds that are similar to soap but are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxylate (of soap) to bind to calcium and other ions found in hard water.
What is soap made out of?
Today, soaps are made from fats and oils that react with lye (sodium hydroxide). Solid fats like coconut oil, palm oil, tallow (rendered beef fat), or lard (rendered pork fat), are used to form bars of soap that stay hard and resist dissolving in the water left in the soap dish.
How lye is made?
To make lye in the kitchen, boil the ashes from a hardwood fire (soft woods are too resinous to mix with fat) in a little soft water, rain water is best, for about half an hour. Allow the ashes to settle to the bottom of the pan and then skim the liquid lye off the top.
How is soap made chemically?
Soaps are water-soluble sodium or potassium salts of fatty acids. Soaps are made from fats and oils, or their fatty acids, by treating them chemically with a strong alkali. First let’s examine the composition of fats, oils and alkalis; then we’ll review the soapmaking process.
Why soap is basic?
Treatment of fats or oils with strong bases such as lye (NaOH) or potash (KOH) causes them to undergo hydrolysis (saponification) to form glycerol and the salt of a long-chain fatty acid (soap). Because soaps are the salts of strong bases and weak acids they should be slightly basic.
What is the structure of soap?
The cleansing action of soap is determined by its polar and non-polar structures in conjunction with an application of solubility principles. The long hydrocarbon chain is of course non-polar and hydrophobic (repelled by water). The “salt” end of the soap molecule is ionic and hydrophilic (water soluble).
How does soap work against bacteria?
In other words, regular soap simply causes bacteria to loosen their grip on your hands, to be rinsed away. That helps explain why using water alone still seems to work just fine, as long as you rub your hands together vigorously. By contrast, antibacterial soap has additives that are designed to kill bacteria outright.
Can soap dissolve in water?
Polar compounds can dissolve in water. Most of what we call dirt is grease or oil which will not come off with just water. This is because oil and grease are non-polar, which means they will not dissolve in the water. Soap can mix with both water and with oil.
Are fats dissolved by soap?
Because of the two different parts of the molecule, a soap molecule is soluble in water and at the same time can dissolve fats. The fats are attracted to the non-polar tail part of the soap while the polar head makes the whole complex (soap + fat molecules) dissolve in water.
Why soap does not work well in hard water?
When soap is added to hard water, the Ca2+ and Mg2+ ions present in hard water react with soap. The sodium salts present in soaps are converted to their corresponding calcium and magnesium salts which are precipitated as scum. The insoluble scum sticks on the clothes and so the cleaning capacity of soap is reduced.
What is the chemical formula of soap?
write the chemical formula as well as structural formula of soaps and detergents. Soaps are sodium or potassium salts of long chain carboxylic acids. The formula for soap is C17H35COONa, or sodium stearate, Detergents: Detergents are generally ammonium or sulphonate salts of long chain carboxylic acids.
What chemicals are in soap?
These chemicals are used to produce lather and bubbles in soap. Some common sulfates are SLS (sodium lauryl sulfate) and SLES (sodium laureth sulfate). Sulfates strip the skin of its natural oils and increase penetration of the skin’s surface. They are also irritants for people with sensitive skin or eczema.
