Industrial commercial fat-based detergents
Healthy Cleaning This section is intended to be a valuable information resource about cleaning products for consumers, educators, students, media, government officials, businesses and others. Water, the liquid commonly used for cleaning, has a property called surface tension. In the body of the water, each molecule is surrounded and attracted by other water molecules. However, at the surface, those molecules are surrounded by other water molecules only on the water side.VIDEO ON THE TOPIC: Soap and Detergent Manufacturers - Ropella

Keeping up with detergent chemistry
The first soaps were manufactured in ancient times through a variety of methods, most commonly by boiling fats and ashes. Archeologists excavating sites in ancient Babylon have found evidence indicating that such soaps were used as far back as B.
By the second century A. In Europe, the use of soap declined during the Middle Ages. However, by the fifteenth century, its use and manufacture had resumed, and an olive-oil based soap produced in Castile, Spain, was being sold in many parts of the known world. Castile soap, which is still available today, has retained its reputation as a high-quality product. During the colonial period and the eighteenth century, Americans made their own soap at home, where most continued to produce it until soap manufacture shifted away from individual homes to become an industry during the s.
The first detergent, or artificial soap, was produced in Germany during World War I. In , the first built detergent appeared, comprising a surfactant a surface-acting agent or soap and a builder a chemical that enhances the performance of the surfactant as well as rendering the laundering process more effective in other ways.
Pushed along by economic prosperity and the development of relatively inexpensive washing machines in the wake of World War II, detergent sales soared; by , they had surpassed soap sales in the United States. Although people commonly refer to laundry detergent as "soap," it is actually a synthetic combination that functions much like soap, with certain major improvements. Soap cleans because each soap molecule consists of a hydrocarbon chain and a carboxylic group fatty acids that perform two important functions.
The carboxylate end of the soap molecule is hydrophilic, meaning that it is attracted to water, while the hydrocarbon end of the molecule is both hydrophobic repelled by water and attracted to the oil and grease in dirt. While the hydrophobic end of a soap molecule attaches itself to dirt, the hydrophilic end attaches itself to water.
The dirt attached to the carboxylate end of the molecule is chemically dragged away from the clothes being cleaned and into the wash water. Properly agitating and rinsing the clothes furthers the cleansing process. The major difficulty with using soap to clean laundry shows up when it is used in hard water—water that is rich in natural minerals such as calcium, magnesium, iron, and manganese.
When these chemicals react with soap, they form an insoluble curd called a precipitate. Difficult to rinse out, the precipitate leaves visible deposits on clothing and makes fabric feel stiff. Even water that is not especially hard will eventually produce precipitates over a period of time. While the hydrocarbons used in soap generally come from plants or animals, those used in detergent can be derived from crude oil. Adding sulfuric acid to the processed hydrocarbon produces a molecule similar to the fatty acids in soap.
The addition of an alkali to the mixture creates a surfactant molecule In the blender method of making powder laundry detergent, the ingredients—surfactant, builders, antiredeposition agents, and perfumes—are simply blended together in a mixer, released onto a conveyor belt, and packaged accordingly. This method is favored by smaller companies.
In addition to a surfactant, modern detergent contains several other ingredients. Among the most significant are builders, chemicals which serve several purposes. Most importantly, they increase the efficiency of the surfactant.
They also sequester minerals in hard water, meaning that they hold them in solution, preventing them from precipitating out. Furthermore, builders can emulsify oil and grease into tiny globules that can be washed away.
Some, like sodium silicate, inhibit corrosion and help assure that the detergent will not damage a washing machine. Still other builders contribute to the chemical balance of the wash water, making sure that it conduces to effective washing. Modern detergents have several other ingredients including antiredeposition agents, chemicals that help prevent soil from settling back on washed clothes. Fluorescent whitening agents are also common.
By converting invisible ultraviolet light into visible blue light, these help to maintain brightness or whiteness. Oxygen bleaches such as sodium perborate improve the detergency of the mixture, especially in low-phosphate or no-phosphate products, as well as helping to remove some types of stains. Processing aids such as sodium sulfate are also used to prevent caking and to standardize product density.
Enzymes and perfumes are also found in commercial detergents. Enzymes a type of protein break down some stains to make them easier to remove and are an essential ingredient in various pre-soak products used to treat heavily soiled clothes prior to laundering. Perfumes or fragrances cover the odor of the dirt and any chemical smell from the detergent itself. Suds control agents also have a role in detergents—too many suds can cause mechanical problems with a washing machine.
Although there are three ways of manufacturing dry laundry detergent, only two are commonly used today. In the blender process favored by smaller companies, the ingredients are mixed in large vats before being packaged. The machines used are very large: a common blender holds 4, pounds 1, kilograms of mixed material, but the blenders can accommodate loads ranging from to 10, pounds to 4, kilograms.
By industry standards, these are small batches for which the blender process is ideal. While some settling may occur, the resulting detergent is of high quality and can compete with detergents made by other processes.
The second commonly used method of production is called the agglomeration process. Unlike the blender process, it is continuous, which makes it the choice of very large detergent manufacturers. The agglomeration process can produce between 15, and 50, pounds 6, and 22, kilograms of detergent per hour.
In the third method, dry ingredients are blended in water before being dried with hot air. Although the resulting product is of high quality, the fuel costs and engineering problems associated with venting, reheating, and reusing the air have led to this method being largely replaced by agglomeration. Manufacturers constantly monitor the quality of their detergents, and they utilize the same testing methods to assess the effectiveness of new products. In one method, light is shined onto a piece of fabric that has been soiled and then washed in the test detergent.
The To make liquid detergent, the dry powder is simply mixed back in with a solution consisting of water and chemicals known as "solubilizers.
A reflection rate of 98 percent is considered quite good and indicates that the detergent has cleaned properly. Another method involves laboratory burning of a small amount of material that has been soiled and then laundered. The weight of the ashes, plus the weight of the gaseous results of the burning, reveal how much of the dirt remained in the fabric after laundering.
A result that is much higher than a clean test sample indicates that a significant amount of dirt was retained in the laundered sample. Naturally, the goal is to come as close to the weight of a clean control sample as possible. In recent years, the laundry detergent industry has been faced with two environmental challenges, both of which have seem to have been dealt with successfully.
Environmentalists were concerned that phosphate builders added large amounts of phosphorous compounds to the nation's waterways. Acting as a fertilizer, the phosphorus stimulated the growth of algae, and these unnaturally large crops of algae significantly depleted the amount of dissolved oxygen in water. This decrease in free oxygen harmed other marine life, thus threatening to disrupt normal ecological patterns.
This problem, and the environmental pressure and legislation it prompted in the late s, led manufacturers to develop effective builders that did not contain phosphates. Today, detergents sold in many states are phosphate-free. Although this adjustment did not entail a change in the manufacturing process, it did require a research effort that took several months to devise a satisfactory alternative.
An earlier environmental problem was that of excess detergent foam appearing in the nation's waterways. In the early s, when home use of washing machines and laundry detergents grew at an explosive rate, there were several instances of large amounts of foam appearing in rivers and streams, although detergent may not have been the only cause of the foaming. Over a period of five years, from to , it was found that a common surfactant, ABS alkyl benzene sulfonate , the detergent ingredient that contributed to foaming, was responsible.
ABS's complex molecular structure did not biodegrade rapidly enough to keep it from foaming once washing water was discharged. A proven replacement was not immediately available. Beginning in , however, manufacturers replaced ABS with LAS linear alkylate sulfonate , which biodegrades rapidly, and since that time, LAS has been the primary foaming agent in detergents.

Cleaning Products , Educational , Simple Science. Back to News. The earliest evidence of soap can be traced back to B. Soap making is mentioned in ancient Roman documents written as early as 70 A. Fast forward to Medieval Europe where soap making is an established craft with centers in France, Spain and Italy. During that time the use of soap was a luxury enjoyed mainly by those who could afford it. Widespread use of soap during this period can be attributed to advertising campaigns touting the relationship between good personal hygiene and health.

The detergent industry is highly competitive, mostly recession proof, and, thanks to chemistry, always changing ever so slightly. It has been years, however, since cleaning chemistry has been the driving force in detergent innovation. Instead, the environment rules in laundry rooms and kitchens.
Simple Science: The Difference Between Soap and Detergent
Laundry detergents have come a long way since the first bar soaps made from animal fat and lye were offered for sale in the s. The introduction of synthetic detergents to the marketplace in the s offered homemakers more options for fabric care. But it was the s that brought the most significant innovation in the laundry, the addition of enzymes that "attack" specific types of stains.

We've seen that carboxylic acid derivatives react with nucleophiles to give substitution products in which the leaving group is replaced by the attacking nucleophile. This same pattern describes the first steps in the reaction of esters with lithium aluminum hydride and Grignard reagents, but in both cases the reaction proceeds further because the first product formed also reacts with the reagent. For an example, lets look at the reduction of an ester with lithium aluminum hydride. When the "hydride ion" H: - from lithium aluminum hydride replaces the OR' group of the ester, an aldehyde is formed.

Laundry detergent , or washing powder , is a type of detergent cleaning agent used for cleaning laundry. Laundry detergent is manufactured in powder and liquid form. While powdered and liquid detergents hold roughly equal share of the worldwide laundry detergent market in terms of value, powdered detergents are sold twice as much compared to liquids in terms of volume. From ancient times, chemical additives were used to facilitate the mechanical washing of textile fibres with water.
