Deep cracks that may bleed When to see a doctor Most cases of dry skin respond well to lifestyle and home remedies. See your doctor if:
Chemical classification of detergents[ edit ] Detergents are classified into three broad groupings, depending on the electrical charge of the surfactants.
Anionic detergents[ edit ] Typical anionic detergents are alkylbenzenesulfonates. The alkylbenzene portion of these anions is lipophilic and the sulfonate is hydrophilic.

Two different varieties have been popularized, those with branched alkyl groups and those with linear alkyl groups. The former were largely phased out in economically advanced societies because they are poorly biodegradable.
Bile acidssuch as deoxycholic acid DOCare anionic detergents produced by the liver to aid in digestion and absorption of fats and oils.
Three kinds of anionic detergents: Cationic detergents[ edit ] Cationic detergents that 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 center is positively charged. Typical non-ionic detergents are based on polyoxyethylene or a glycoside. Common examples of the former include TweenTritonand the Brij series. These materials are also known as ethoxylates or PEGlyates and their metabolites, nonylphenol.
Glycosides have a sugar as their uncharged hydrophilic headgroup. Examples include octyl thioglucoside and maltosides. See surfactants for more applications.The Soap and Detergent Association Risk Assessment Guidance for Enzyme-Containing Products. Soaps form a scum in hard water, which is not easy to rinse away and is known to turn laundry, a grayish hue.
The insoluble film that soap leaves can leave a residue on the laundry same like as would see in a shower stall where hard water is present.
Symptoms. Dry skin is often temporary — you get it only in winter, for example — but it may be a lifelong condition. Signs and symptoms of dry skin depend on your age, your health, where you live, time spent outdoors and the cause of the problem.
Soaps, will react with metal ions in the water and can form insoluble precipitates.

A fatty acid is an organic compound most often of animal or plant origin.
Detergents have some similarities. But are often of synthetic origin. They. Soaps and detergents may also remove the protective waxes that cover the insect, causing death through excess loss of water.
