A great number of detergent compositions using a-sulfo fatty acid esters are given in the patent literature. The a-ester sulfonates are major or minor components, besides other surfactants and builders [68-76]. Some examples of laundry and dishwashing detergents are given below. 

Typically, there are five different compositions of laundry detergents, shampoo, and dishwashing powder ... 

The composition of a typical powdered laundry detergent is given below ... 

It is useful in perfume compositions for, for example, laundry detergents. 

Rogers [1] and Blokzijl [2] used substituted polysaccharides as macroinitiator intermediates for the preparation of polysaccharide graft polymers and in the preparation of macroinitiators. The polysaccharide graft polymers were designed to impart sod release and/or fabric care benefits to laundry detergent or fabric treatment compositions. 

The final and most important component of the evaluation of laundry detergents is the consumer test. A select group of consumers is provided with a product and instructed to use it with their normal laundry loads. Their feedback on various aspects of cleaning and product aesthetics is collected and analyzed. These data play a significant role in any decision regarding the composition of the liquid laundry detergent. 

Most of the emphasis in this section has focused on the expanding boundaries of patent art and technology, and ascertaining its impact on future (liquid) detergent compositions. The laundry detergent markets in the U.S., Europe, and Japan... 

Studies have shown zeolites to be slower than STPP at removing Ca2+ from the wash solution [27], In addition, their insolubility in aqueous solutions has limited their use to powder detergents, especially in the laundry industry. A comprehensive review of the chemistry of aluminosilicates in detergent compositions is available [28], Patents for LADD products utilizing zeolites have appeared in the literature [29-31]. The attraction is due to their low cost and low toxicity. 

Detergents Choose a laundry detergent to research and write an essay about its chemical composition. Explain how it removes oil and grease from fabrics. 

At the same time, surfactants like alkylbenzene sulfonates remain the most widely used basis for laundry detergents. Anionics remain the main products for making detergent compositions. Some of the application aspects of relatively new types of anionics (a-olefin sulfonates, sulfocarboxylic acids, alkyl phosphates etc.), whose commercial manufacture began in the 60-ties - 70-ties of the 20 century, are described by Stache [95]. The application of conventional types of nonionics like ethoxylated alcohols or alkyl phenols is presented in [13 -14], Alkyl polyglycosides were widely used in the last 5-8 years [96]. However, the main tendency in the development of new generation detergents is the use of surfactant mixtures in their optimum composition [97, 98]. 

A wide range of perfumes, predominandy based on synthetic ingredients, are used in household products. They are used to make cleaners smell more pleasant than their chemical ingredients. Some of the cleaners that usually contain fragrances in their compositions are softeners and laundry detergents, dishwashing products, floor cleaning products, furniture polish, and bathroom cleaners. Air fresheners also contain perfumes in their formulations. 

Laundry detergents vary widely in compositions and particular uses and can be partial-built, complete-built, prewash, main wash, bleaching, or enzyme detergents. The liquid detergents can be structured or unstructured.
