Stabilizing agents potassium chloride

The level of glucosamine base in a formulation depends upon whether the sulfate, hydrochloride, or A-acetyl form used is present as base or salt and included levels of either potassium or sodium chloride added as a stabilizing agent. ... 

Potassium chloride is also used widely in the food industry as a dietary supplement, pH control agent, stabilizer, thickener, and gelling agent. It can also be used in infant formulations. 

Sometimes sodium or potassium chloride (0.18-1.0%) is added to the desizing bath for pancreative enzymes to get its full activity. For malt a-amylase calcium ion is effective and sequestering agent must be avoided in the desize bath. These salts are particularly used for desize mixture by affording heat protection to enzyme, increased stability of the enzyme and efficiency. On the other hand, heavy metal ions such as copper, iron etc. may combine with enzyme and inhibit its activity [8]. Sometimes hydrocarbon solvents such as xylene (50 ml/1) along with suitable emulsifier (4 g/1) are also added to facilitate removal of waxy components of the size.

Complexing agents, which act as buffers to help control the pH and maintain control over the free metal—salt ions available to the solution and hence the ion concentration, include citric acid, sodium citrate, and sodium acetate potassium tartrate ammonium chloride. Stabilizers, which act as catalytic inhibitors that retard the spontaneous decomposition of the bath, include fluoride compounds thiourea, sodium cyanide, and urea. Stabilizers are typically not present in amounts exceeding 10 ppm. The pH of the bath is adjusted. 

In regards to necrosis, it is clear that the old adage an ounce of prevention is worth a pound of cure applies. Agents that stabilize ion homeostasis have proved to be effective in preventing necrosis in cell culture studies. For example, drugs that activate plasma membrane potassium ion channels or chloride ion channels can prevent membrane depolarization and so inhibit sodium and calcium ion influx. Agents that prevent large sustained increases in intracellular free calcium levels can also prevent neuronal... 

A systematic study of the influence of salts on foam films formed from nonionic surface active agents was carried out in these laboratories (3, 6). This paper reports an investigation of the effects of sodium chloride and potassium thiocyanate on the thickness of foam films formed from DMS. In addition to measurements on films, the electrophoretic mobilities of dodecane droplets stabilized with DMS were determined as a function of salt concentration, and the properties of insoluble mono-layers of octadecylmethyl sulfoxide (OMS) at the air-water interface have been examined using the classical methods largely developed by N. K. Adam (7). 

Chloroform is also prepared by chlorination of methane but also by treatment of ethanol with bleaching powder. Because of its tendency to decompose, chloroform contains phosgene, hydrogen chloride, and chlorine as well as other chlorination products of methane it is usually stabilized by addition of 0.5-1.0% of ethanol. The impurities formed by decomposition are removed by washing with water or dilute potassium hydroxide solution. Further purification, which is usually superfluous, can be effected as for methylene dichloride. The same drying agents as in that case may be used of these, calcium chloride and phosphoric oxide are most efficient in removing also the ethanol. 

Potassium trisiamylborohydride can now be made in a convenient manner and the reaction of cyclic boronic esters possessing a wide variety of sterlc requirements with potassium hydride gives rise to the corresponding borohydrides. These represent a new class of reducing agents whose stability and reactivity have been explored. Copper(I) alkylborohydrldes are obtained from 1 1 mixtures of cuprous chloride and sodium borohydride on reaction with alkenes in THF.
