Sodium ethylxanthate is a chemical substance.

Sodium ethylxanthate is a yellow to brown powder that is soluble in water and ethanol. It has the characteristics of thickening and stabilizing lotion and gel.

The preparation method of sodium ethylxanthate is generally through chemical synthesis. Reacting xanthan acid with sodium hydroxide to produce the intermediate of sodium xanthate. Then, through esterification reaction, ethanol is reacted with the intermediate of sodium xanthate to obtain ethyl sodium xanthate.
It should not come into contact with the skin, eyes, and mucous membranes to prevent irritation and damage. When using, gloves and protective goggles should be worn, and good ventilation in the work area should be ensured.

Sodium Hydrosulfite 90 technical grade is widely used in the textile industry for reducing dyeing reduction cleaning printing and decolorization and as a bleaching of silk wool nylon and other fabrics It can also be used in organic synthesis such as dyes pharmaceuticals as a reducing agent or bleach Sodium Hydrosulfite is the most suitable bleaching agent for wood pulp paper Its used for chemical processing cleaners gas purification and environmental improvement
