Caustic Chemicals Used in Soap Making

Soap keeps our world safe. It cleans homes and businesses, offices, and manufacturing plants — versatile, gentle, and effective, it is in many ways the essential product. Without soap, proper sanitation is nearly impossible. Humans have made basic soaps for millennia — archaeologists have found fragments of soap recipes dating from as early as BCE. According to one legend, the word "soap" comes from ancient Rome, where animal fat unintentionally mixed with wood ash during religious ceremonies on Mount Sapo.

People discovered the resulting paste was an effective cleaning agent, and they called it "sapo" in recognition of its origins. However, soap-making has evolved since Rome, and modern soap looks much different. What is the process of producing soap, and what are its chemical components?

In this guide, we will provide an overview of the typical chemicals involved with liquid soap production, as well as examine the differences between liquid soaps and other everyday cleaning products. For centuries, humans have known the basic recipe for soap — it is a reaction between fats and a strong base.

The final molecule is called sodium stearate and is a type of salt. Depending on the metal cation, soaps are either potassium salts or sodium salts arranged as long-chain carboxylic acids. Typically, the formation of these chains involves combining potassium hydroxide with an animal or vegetable fat, or sometimes with acetic acid. A soap molecule does two things — it bonds to both water and debris. That is due to its hydrophilic, or "water-loving," and hydrophobic, or "water-fearing," components.

A molecule of soap has a hydrophilic anionic "head" and a hydrophobic "tail" made of hydrocarbons. The head of the molecules is attracted and dissolves in water, while the hydrocarbon tail is attracted to dirt and grease, and repelled by water. Soap is also a surfactant — it reduces the surface tension of water. Water has a strong surface tension , which causes drops to bead on a variety of surfaces ranging from metal to fabric.

That slows water's wetting process and inhibits its ability to clean. Because soaps lessen the surface tension of water, it can spread and wet more easily. Also, surfactants loosen and emulsify dirt and debris, dispersing it in water and allowing it to get rinsed away.

Today, the process of making soap most commonly involves reacting an organic acid with an alkaline chemical like potassium hydroxide or sodium hydroxide. Industrially, the caustic soda base used most often is sodium hydroxide, which is also called lye.

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

A standard method involves the saponification of oils and fats, which requires heat. In this method, fats and oils get heated and then reacted against a liquid alkali — this process produces soap, plus excess water and glycerine.

Another common way to make soap is by neutralizing fatty acids with an alkali, most often sodium hydroxide. First, oils and fats get hydrolyzed, or split, using high-pressure steam. This step separates the fats into crude fatty acids and glycerine. Next, the fatty acids get purified through distillation and then neutralized by an alkali, which produces soap and water. If the alkali is potassium hydroxide , the result is a potassium soap.

Potassium soaps are the "soft" liquid soaps that quickly dissolve in water. Alternately, if the alkali is sodium hydroxide, the result is a sodium soap. These are called "hard" soaps and are less water-soluble than soft soaps. In modern liquid soaps, the ingredient list extends far beyond fats and bases. Below is a list of the seven most common ingredients in liquid soap, along with their functions.

Water-based soap will need a preservative — if not, the product can become rancid and develop mold and bacteria. Even cold-process soaps made without water will need preservatives if they will contact water, which is true of most cleaning products.

Sodium benzoate is the sodium salt of benzoic acid , used as an anti-corrosive and preserving agent in a wide range of industries. It goes by a variety of names, including benzoate of soda, sobenate, natrium benzoicum, and benzoic acid. In cleaning, sodium benzoate is beneficial for its antifungal and intrinsic preserving qualities. As a preservative, sodium benzoate extends the shelf life of liquid soap and prevents fungi like yeast and mold from colonizing.

Sodium benzoate is often an alternative to parabens in cleaning products such as dishwashing detergent, toilet bowl cleaners, and upholstery cleaners. Sodium laureth sulfate SLS is both a surfactant and emulsifier and contributes a sudsing and foaming element in soap. Also known as sodium dodecyl sulfate , SLS is highly effective at removing oils and residues. Since it can clean grease from engines and floors, industrial settings often use liquid SLS soaps in high amounts.

For personal care soaps and household products, SLS is more common in less concentrated amounts. In addition to emulsifying oils, SLS suspends dirt and soil in water, allowing it to wash away easily. It reduces the surface tension of water, allowing it to more thoroughly wet and clean surfaces.

Both chemicals individually work to inhibit bacteria growth, but they are most often combined. Powerful biocides , they eradicate the slime-forming fungi, algae, and bacteria that can develop in many industrial settings, including fuel storage tanks, water cooling systems , paper , and pulp mill water systems and oil extraction systems. CAPB derives from chemicals found in coconut oil and is the result of mixing raw coconut oil with the chemical dimethylaminopropylamine.

Classified as an amphoteric surfactant detergent, CAPB can function as either an acid or a base, depending on its chemical surroundings. With a polar head and a hydrocarbon tail, CAPB helps soap break down debris and wash it away in water. CAPB acts as a thickening agent in many liquid soaps. CAPB also has some antiseptic properties, which makes it a common addition in personal sanitary products.

Many liquid soaps contain some fragrance. The exact ingredients vary from manufacturer to manufacturer — currently, the law doesn't require the fragrance industry to disclose the specific chemicals they use in their scents. In one fragrance, there could be hundreds of ingredients or just a few — more than 3, oils and chemicals are approved for use in fragrance products.

These add a perfuming element to soap, helping it deodorize as well as clean surfaces. Synthetically produced fragrance oils are the most popular choices for scented liquid soaps. When compared to other fragrance options like essential oils, synthetic fragrances are inexpensive and relatively easy to produce.

That makes them an economical and attractive choice for many companies. In chemistry, pH is the measure of the acidity or alkalinity of a solution or surface. The higher the pH number, the more alkaline a substance is — low numbers indicate acidity.

A neutral pH is seven — pH numbers lower than seven are acidic, and numbers higher than seven are alkaline. The human body has a natural pH of 7.

By nature, soap is an alkaline substance and will have a high pH balance. However, if a soap will come into contact with humans, it should never have a pH higher than 10 — the closer the soap's pH is to the pH of human skin, the better.

If the pH of the soap is too high, it will be irritating and even toxic to humans. In liquid soaps, some chemical ingredients alter the pH balance of soap. Most often, the pH adjusters in liquid soaps will be citric acid or sodium chloride. Citric acid is a naturally occurring chemical in citrus fruits and results from the fermentation of carbohydrates. An acid, this product lowers the pH of soaps, making them less alkaline.

Citric acid enhances the effectiveness of preservative and antioxidant ingredients in soaps. Sodium chloride, or salt, reduces the pH of soap solutions. It acts as a stabilizing agent, helping pH levels remain steady. A thickening agent, sodium chloride also has a de-greasing effect, enhancing the cleaning potential of liquid soap.

In liquid soaps, dyes give the soap an appealing color. Like fragrances, the exact ingredients of synthetic dyes depend on the specific manufacturer. Often, they chemically derive from petroleum and coal tar. The purpose of dyes is purely aesthetic — they make the product visually appealing and have little to no functional value. Because of this, many companies choose synthetically produced dyes and colorants, as opposed to naturally derived compounds, since synthetic dyes are almost always cheaper and more readily available.

The best dyes have long-term color stability and resist fading. Common color choices for liquid soaps are yellow, blue, and green, but the right dye can achieve almost any color. Sodium hydroxide , also called caustic soda or lye, is a traditional ingredient for soap-making. While potassium hydroxide is more common in liquid soap-making, it is possible to produce liquid soaps using caustic soda.

One of the most commonly used chemicals in the soap industry, sodium hydroxide is a strong base with a broad range of potential applications.

Sodium hydroxide is a water-soluble compound that comes in pellets, granules, flakes, or powders. Sodium hydroxide forms through the electrolysis of sodium chloride, and is a powerful alkali.

When added to water, sodium hydroxide increases the pH of a substance, which makes it a valuable pH adjuster in acidic formulas. An inorganic base, sodium hydroxide does not contain any carbon atoms, similar to water. When mixed with water, sodium hydroxide dissociates completely to just hydroxyl and sodium ions.

The hydroxyl ions carry a negative charge, and the sodium ions have a positive one. This influx of ions leads to a strong exothermic reaction, which helps hydrolyze fats in the saponification process to form soaps. Sodium hydroxide is a reagent, or a substance used in a chemical reaction to produce other substances.

Caustic soda causes saponification and is an essential ingredient in soap-making.

Soap Manufacturing Process

Soaps are cleaning agents that are usually made by reacting alkali e. A soap is a salt of a compound known as a fatty acid. A soap molecule consists of a long hydrocarbon chain composed of carbons and hydrogens with a carboxylic acid group on one end which is ionic bonded to a metalion, usually a sodium or potassium. The hydrocarbon end is nonpolar and is soluble in nonpolar substances such as fats and oils , and the ionic end the salt of a carboxylic acid is soluble in water. Soap is made by combining tallow or other hard animal fat or vegetable or fish oil with an alkaline solution. The two most important alkalis in use are caustic soda and caustic potash. A detergent is an effective cleaning product because it contains one or more surfactants.
