What's a Soap-free Cleanser? Soap is made of a compound of natural oils or fats with sodium hydroxide or another strong alkaline solution, Dr. Banks says. It is mainly used as a surfactant for washing, bathing and cleaning.. So that means soapless products are made without the combination of fats and alkaline products. But taking out the soap doesn't mean there is no lather. Most soap-free products lather just as well as soap products, Dr. Bank says.

High-Quality Sodium Hydroxide ( NaOH) and Potassium Hydroxide ( KOH) for Making Soap Calculating and Measuring Water. Water is needed to dissolve the lye (sodium hydroxide) and for the hydrolysis of the fats. Using too much water may produce soft bars of soap, may demand extra drying time, or may encourage rancidity.alculating and Measuring Water.

How Saponification Makes Soap Hydrolysis of the fats and oils occurs, yielding glycerol and crude soap. In the industrial manufacture of soap, tallow (fat from animals such as cattle and sheep) or vegetable fat is heated with sodium hydroxide. Once the saponification reaction is complete, sodium chloride is added to precipitate the soap. The water layer is drawn off the top of the mixture and the glycerol is recovered using vacuum distillation. The crude soap obtained from the saponification reaction contains sodium chloride, sodium hydroxide, and glycerol.

What is Lye? Lye is a caustic, alkaline chemical that is useful for many purposes but also is hazardous. It can dissolve sticky substances such as fat and has a high degree of reactivity with other materials. Modern lye typically is the chemical sodium hydroxide, but potassium hydroxide was once the chemical compound that was commonly used.

Lye Lye is a stronger alkaline than baking soda or sodium bicarbonate, with a pH reading ranging from around 13 to 14.2 Its base of sodium hydroxide is created commercially by the electrolysis of sodium chloride solution, as well as reacting calcium hydroxide with sodium carbonate, according to the FDA.

- A mixture of tallow (animal fat) and coconut oil is mixed with sodium hydroxide and. heated. The soap produced is the salt of a long chain carboxylic acid. Step 2 - Glycerine removal. Glycerine is more valuable than soap, so most of it is removed. Some is left in the soap to. help make it soft and smooth.

Ingredients -- Sodium stearate is one of the main compounds in common soap. To make soap, you start with beef fat. If you treat beef fat with steam you get tallow, a mixture of fats, one of which is glyceryl tristearate, a tri-glyceride containing three stearic acid molecules attached to a glycerine molecule.

Can You Make Soap Without Lye (Sodium Hydroxide)? Lye is also made from wood ash, but that lye is inconsistent and makes a very soft bar. If you want to learn how to make lye this way, there are many tutorials available on the internet. I’ve wanted to try making Black Soap using banana leaves that is done much the same way.

- Lye is commonly the alternative name of sodium hydroxide (NaOH) or historically potassium hydroxide (KOH). Today, sodium hydroxide is commercially manufactured using a membrane cell chloralkali process. It is one of the highest volume industrial chemicals with world-wide annual production of 45 million tons in 1998.

What chemical compound (s) make up soap? Best Answer: Soap is made from boiling fat with lye. Sodium or potassium hydroxide can be used for the lye. Any fat will work. The lye splits the fat, a triglyceride into fatty acids and glycerol. The fatty acid combine with the sodium to produce soap, sodium oleiate ,

Base Oils Water. Water is used to create the lye solution that is mixed into the oils. The amount of water is dependent on the specific soap recipe, but it must be enough to allow the lye and oil molecules to get together and make soap, but not so much as to result in a soft bar of soap.Much of the water evaporates out of the soap as it cures and ages.here are two types of lye used by soapmakers-sodium hydroxide and potassium hydroxide. Sodium hydroxide is used to make solid soap; potassium hydroxide is used to make liquid soaps. A combination of the two is used to make cream soaps.

What is Lye Soap? Additionally, lye soap doesn't contain fragrances or other synthetic ingredients that can irritate skin, so many people with conditions like eczema and psoriasis use it too. It is also commonly used to relieve the itching caused by insect bites, poison ivy, and sunburn.

How Does Soap Work? Soaps are sodium or potassium fatty acids salts, produced from the hydrolysis of fats in a chemical reaction called saponification. Each soap molecule has a long hydrocarbon chain, sometimes called its 'tail', with a carboxylate 'head'. In water, the sodium or potassium ions float free, leaving a negatively-charged head. Soap is an excellent cleanser because of its ability to act as an emulsifying agent.

Detergents and soaps A detergent is a chemical substance you use to break up and remove grease and grime, while soap is simply one kind of detergent. Soap has a long history and was originally made from purely natural products like goat's fat and wood ash.

- Sodium soaps are hard soaps. When the alkali is potassium hydroxide, a potassium soap is formed. Potassium soaps are softer and are found in some liquid hand soaps and shaving creams. The carboxylate end of the soap molecule is attracted to water. It is called the hydrophilic (water-loving) end.

High-Quality Sodium Hydroxide ( NaOH) and Potassium Hydroxide ( KOH) for Making Soap . People often think of lye soap as a soap that is unpleasant to use because too much lye was used in the soap formula and lye (sodium hydroxide) remained in the bar of soap to irritate and burn the skin.Soap cannot be made without using lye. When made correctly, no lye will remain in the bar of soap.aponification is the chemical process of making soap that involves an exothermic reaction between lye (sodium hydroxide) and a fat (usually oils). What is commonly known as. yields a glycerin-rich soap, which used to be referred to as. .

How to Make Soap (With or Without Lye) In other words, without Lye, you just have a bucket of chunky, fatty oils floating in water. The important part is to make sure that the correct amount of Lye is used for the particular soap you make (more on that below) as different oils and fats require different ratios of lye.
