This essay focuses on compounds similar to soap.. Detergents, like soaps, work because they are amphiphilic. Partly hydrophilic (polar) and partly hydrophobic (non-polar). Their dual nature facilitates the mixture of hydrophobic co
For each of the following brands/products, determine which of the five generic strategies are being used. Give your reasons. · Swatch watch · McDonald’s Dollar Menu ·
These substances are usually alkylbenzene sulfonates. A family of compounds 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.
In domestic contexts, the term detergent by itself refers specifically to laundry detergent or dish detergent. As oppose to hand soap or other types of cleaning agents. Detergents are commonly available as powders or concentrated solutions. Detergents, like soaps, work because they are amphiphilic. Partly hydrophilic (polar) and partly hydrophobic (non-polar). Their dual nature facilitates the mixture of hydrophobic co
The alkylbenzene portion of these anions is lipophilic and the sulfonate is hydrophilic. Two different varieties have been popularize, those compounds similar to soap with branche alkyl groups and those with linear alkyl groups. The former were largely phase out in economically advance societies because they are poorly biodegradable. An estimated 6 billion kilograms of anionic detergents are produce annually for domestic markets.
Bile acids, such as deoxycholic acid (DOC), are anionic detergents produce by the live to aid in digestion and absorption of fats and oils.
Cationic detergents are similar to the anionic ones, with a hydrophilic component, but. Instead of the anionic sulfonate group, the cationic surfactants have quaternary ammonium as the polar end. The ammonium sulfate compounds similar to soap center is positively charge
Typical non-ionic detergents are based on polyoxyethylene or a glycoside. Common examples of the former include Tween, Triton, and the Brij series. These materials are also know as ethoxylates or PEGylates and their metabolites, nonylphenol. Glycosides have a sugar as their uncharged hydrophilic headgroup. Examples include octyl thioglucoside and maltosides. HEGA and MEGA series detergents are similar, possessing a sugar alcohol as headgroup.
Zwitterionic detergents possess a net zero charge arising from the presence of equal numbers of +1 and −1 charged chemical groups. Examples include CHAPS
mpounds (like oil and grease) with water. Because air is not hydrophilic, detergents are also foaming agents to varying.
