The chemistry of soap manufacturing stayed essentially the same until 1916. During World War I and again in World War II, there was a shortage of animal and vegetable fats and oils that were used in making soap. Chemists had to use other raw materials instead, which were “synthesized” into chemicals with similar properties.
A detergent is a surfactant or a mixture of surfactants with cleansing properties in dilute solutions. These substances are usually alkylbenzene sulfonates, 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.
Jun 01, 2017·Preparation of detergents During the preparation of detergents, a long- chain hydrocarbon obtained from petroleum fractions is converted into an organic acid through a series of steps. The organic acid is then neutralised with sodium hydroxide solution to produce a neutral salt which is a detergent.
Mar 25, 2020·Detergent is an emulsifying agent that is scientifically referred to as sodium dodecyl benzene sulphonate and has a chemical formula of C18H29NaO3S. This chemical compound has an incredible foaming ability, and can be easily compounded with various other additives.
Sep 13, 2020·Soaps and Detergents Last updated; Save as PDF Page ID 5871; Contributors; Carboxylic acids and salts having alkyl chains longer than eight carbons exhibit unusual behavior in water due to the presence of both hydrophilic (CO 2) and hydrophobic (alkyl) regions in the same molecule.Such molecules are termed amphiphilic (Gk. amphi = both) or amphipathic.
Jun 06, 2020·Detergents can be defined as sodium or potassium salts of long-chain benzene sulphonic acid. Detergents can be biodegradable or non-biodegradable. The detergents having a branched hydrocarbon chain are included in non-biodegradable detergents. Detergents can work well with hard water, saline water, or acidic water.
One of the most basic and yet important applications of chemistry in our everyday lives is soap. In fact, all types of cleaning agents, which includes soaps and detergents, are made from chemicals. Let us learn about these cleansing agents in some detail.

Detergent builders (or chelating agents) are important components of soaps and detergents in that they complex with polyvalent cations in aqueous solution and eliminate the harmful effects of metallic impurities (Erickson et al., 1970). ... Surface and Interface Chemistry of Clay Minerals.
Dec 10, 2010·Detergents are a class of chemical compounds that are used for cleaning because of their dual hydrophobic and hydrophilic properties. Due to its chemical structure and reactivity, a detergent can bind to an oily stain and be washed away in water, making it ideal for cleaning. The chemistry behind a detergent is pretty basic and can be understood with little effort.
2. Prepare a detergent solution by dissolving about 1 g your laboratory made detergent in 60 mL (4 tablespoons) of warm water. . (Distilled water is preferred, but not essential) (If desired, you can prepare solutions of your lab detergent and a household detergent.) 3. Dip a clean glass stirring rod into each solution, the soap and the detergent.
Detergent. Detergents have some similarities. But are often of synthetic origin. They are not made insoluble by hard (mineralized) water. Instead of a carboxylic acid group, detergents contains a more intensely ionic group. It may be a sulfate or a sulfonate group (-OS(O) 2-OH). In addition, detergents can include aromatic rings.
Dirt and stains typically consist of particles such as minerals from soil, protein and other organic matter from living things, or bits of black carbon. The particles are trapped on cloth fibers by grease and oil, which cannot be dissolved in water. By understanding the chemistry of stain removal, you can solve almost all stain problems. Don't procrastinate. The sooner you attend to a stain ...
Dec 29, 2017·Detergent powder, or commonly known as “bleach” are mixtures of many chemical compounds which are similar to soap but are less affected by hard water. The following are the ingredients of Ariel detergent: * Alcohol Ethoxylate (AE) Non-ionic surfac...
Jan 16, 2020·A detergent is a surfactant or mixture of surfactants that has cleaning properties in dilute solution with water. A detergent is similar to soap, but with a general structure R-SO 4-, Na +, where R is a long-chain alkyl group.Like soaps, detergents are amphiphilic, meaning they have both hydrophobic and hydrophilic regions.
The detergent molecules also help to make the washing process more effective by reducing the surface tension of the water. Surface tension is the force which helps a blob of water on a surface hold its shape and not spread out. The surfactant molecules of the detergent break apart these forces and make water behave, well, wetter! Back to the top.
Polyglucosides, or detergents that work in hard water, consist of paired glucose molecules with hydrophobic side chains. Soap Molecule A soap molecule consists of a long-chain fatty acid, which undergoes a reaction with an alkaline substance, a process that gives the acid a hydrophilic end and a hydrophobic end.
May 27, 2011·To know what is required to achieve effective cleaning, it is necessary to have a basic understanding of the chemistry of soaps and detergents. Water, the liquid, which is primarily used for cleaning, has a characteristic known as surface tension. Under the surface of water, each water molecule is surrounded and attracted by other molecules. ...
This is why the GDCh-division “Detergent Chemistry” was founded in Bamberg in 1974. Currently the division has 400 members. The aim of the Detergent Chemistry division is to create a forum of interested persons from industry, governmental agencies, universities, institutes and media in which discussions about all technical questions ...
Detergents, as we have learned so far, consist of surfactants, chelating agents and builders. Remember that surfactants are designed to remove dirt from a soiled surface. Chelating agents and builders are added to the formula to keep water hardness from interfering with the cleaning process.
