Water-based cerumenolytics, including water itself, work by hydrating ear wax, fragmenting corneocytes (a type of skin cell) within the ear wax itself. [1] Cerumenolytics with peroxides release oxygen upon contact with the skin, inducing effervescence (bubbling) that mechanically fragments ear wax. [ 9 ]
All-purpose cleaners are usually concentrated solutions of surfactants and water softeners, which enhance the behavior of surfactant in hard water. Typical surfactants are alkylbenzene sulfonates, an anionic detergent, and modified fatty alcohols. A typical water softener is sodium triphosphate.
Side effects of oral minoxidil may include swelling of the face and extremities, rapid heartbeat, or lightheadedness. Cardiac lesions, such as focal necrosis of the papillary muscle and subendocardial areas of the left ventricle, have been observed in laboratory animals treated with minoxidil. [ 8 ]
Other options include topical or systemic spironolactone or flutamide, although they have a high incidence of feminising side effects and are better tolerated in female androgenic hair loss. More advanced cases may be resistant or unresponsive to medical therapy, however, and require hair transplantation.
In the 1960s scientists recognized that phosphates in water caused eutrophication. [23] There was disagreement at that time about whether water with high phosphate came to have the chemical because of somehow being polluted with it. [23] By the 1970s it was established that high phosphate levels in water were a consequence of pollution. [23]
Condensate polishers are important in systems using the boiling and condensing of water to transport or transform thermal energy.Using technology similar to a water softener, trace amounts of minerals or other contamination are removed from the system before such contamination becomes concentrated enough to cause problems by depositing minerals inside pipes, or within precision-engineered ...
It is also used as a precipitating water softener, which combines with hard water minerals (calcium- and magnesium-based minerals) to form an insoluble precipitate, removing these hardness minerals from the water. [5] It is the carbonate moiety which forms the precipitate, the bicarbonate being included to moderate the material's alkalinity.
Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ...
