Wetting agents, soaps

In environmental stress cracking the material fails by breaking when exposed to mechanical stress in the presence of organic liquids or wetting agents (soap solutions, etc.). A well-known example is the action of carbon tetrachloride in polycarbonate a little drop of this liquid on a strip of this polymer causes a very fast cracking upon a little bending of the strip.

Use Alkyd resins, wetting agents, soaps, detergents, cosmetics, insecticides, food additives. 

Lubricating and anti-tack solutions are water-based and include a wetting agent (soap or detergent) and a powder such as magnesium silicate, calcium carbonate, etc. 

Amidosulfonates. Amidosulfonates or A/-acyl-A/-alkyltaurates, are derived from taurine, H2NCH2CH2S02Na, and are effective surfactants and lime soap dispersants (Table 9). Because of high raw material cost, usage is relatively small. Technically, amidosulfonates are of interest because they are stable to hydrolysis, unaffected by hard water, and compatible with soap. They have been used in soap—surfactant toilet-bar formulations. With shorter, acyl groups, they make excellent wetting agents. 

Aqueous solutions of non-electrolytes, especially of non-polar solutes, may show the reverse effect and increase the proportions of ice-like components. The non-polar part of organic electrolytes such as soaps and wetting agents may predominate in increasing the ice component. Thus solutes can be divided into two classes structure making and structure breaking, and in some metal-finishing process solutions both types of solute may be added. 

Many rubber compounds have a tendency to stick in the mould cavity after vulcanisation and require some type of mould release agent. The substances used are surface-active materials such as detergents, soaps, wetting agents, silicone emulsions, aqueous dispersions of talc, mica and fatty acids, applied by spray or brush. Alternatively, dry types based on polytetrafluoroethylene or polyethylene, usually carried in a solvent, can be aerosol applied. An alternative is the addition of an incompatible material to the rubber compound which will bleed to the rubber surface during vulcanisation.

Emulsifiers and wetting agents (detergents and/or surfactants) are composed of anionic, cationic, or nonionic detergents, metal soaps, polyamines, and tall oils or fatty acids [28]. They facilitate the formation of a stable dispersion of insoluble liquids in water (invert-emulsion). Wetting agents are used to ensure that the solids in mud... 

WETTING AGENT. A surface-active agent that, when added to water, causes it to penetrate more easily into, or to spread over the surface of, another material by reducing Hie surface tension of Lite water. Soaps, alcohols, and fatty acids are examples. 

Aqueous suspensions comprise a wide range of adhesives. These will contain as additives the various soaps, surfactants, and wetting agents necessary to stabilize the emulsion or latex. Additives are also incorporated into aqueous formulations to provide system stability under repeated freeze-thaw cycles during storage. 

The ability of soap to help wet a surface makes it a good surfactant or wetting agent . The major problem with soap is that, with any calcium ions present, as in...
