Surfactants hand soaps

The wax glycol distearate is added to make shampoos opaque and pearlescent. It has tiny flakes that mix well with surfactants, and stay in solution. They also add shear-thinning qualities, making liquid hand soaps pump out of the bottle more easily. 

Near the surfactant region the crystalline or lamellar phase is found. This is the region one finds in hand soaps. The ordinary hand soap is mainly the salt of fatty acid (coconut oil fatty acids or mixtures [85%] plus water [15%] and some salts. X-ray analyses have shown that the crystalline structure consists of a layer of soap separated by a water layer (with salts). The hand soap is produced by extruding under high pressure. This process aligns the lamellar crystalline structure lengthwise. If the degree of expansion versus temperature is measured, the expansion will be found... 

Surfactants and Detergents Uses. Perhaps tire largest use of sulfonic acids is the manufacture of surfactants and surfactant formulations. In almost till cases, the parent sulfonic acid is an intermediate which is converted to a sulfonate prior to use. The largest volume uses for sulfonic acid intermediates arc the manufacture of heavy-duty liquid and powder detergents, light-duty liquid detergents, hand soaps (see Soaps), and shampoos. 

Many anionic surfactants can react with a cationic dye such as methylene blue to form strong ion pairs that can be extracted by a suitable organic solvent and can be determined using colorimetric techniques. The anionic surfactants that respond to the methylene blue test are primarily the sulfonate (RS03 Na+) and the sulfate ester (R0S03 Na+) type substances. On the other hand, soaps and the alkali salts of fatty acids (C-10 to C-20) used in certain detergents do not respond to the above test. The various anionic surfactants and their characteristic structural features are presented in Figure 2.32.1. 

In personal care, washing involving the body, hair and teeth is the fundamental application of surfactants and there are also important roles played by surfactants as emulsifiers in skin care products. In the late 1970s the hand soap market was revolutionised by the introduction of liquid soaps based on synthetic surfactants as opposed to the bar soaps based on natural...

Soaps are still major components of modem detergents, On the one hand, the formation of lather will be controlled by the addition of soap with long carbon chains. On the other hand, soaps based on coconut oil acids are components of liquid soaps, where they form lime soap by reaction with the components in hard water. In this way, they bind the polyvalent ions resulting from the water hardness. The formed insoluble lime soap is dispersed by an excess of soap or by other surfactants in the product so that it cannot deposit on the fibres. The major application of soap lies mainly in the field of human cleansing agents. Toilet soaps with different properties are easily obtained by the addition of lime soap dispersants, perfume oils, re-fatting agents, herbal extracts and other active substances.

Liquid hand soaps are concentrated surfactant solutions that can be simply applied from a plastic squeeze bottle or a simple pump container. The formulation consists of a mixture of various surfactants such as alpha olefin sulphonates, lauryl sulphates or lauryl ether sulphates. Foam boosters such as cocoamides are added to the formulation. A moisturizing agent such as glycerine is also added. A polymer such as polyquaternium-7 is added to hold the moisturizers and to impart a good skin feel. More recently, some manufacturers used alkyl polyglucosides in their for-...
