Is potassium hydroxide harmful to the skin?

The main use of potassium hydroxide is relatively wide in the industrial scope. It can be mainly used in the production of many fuels and elements. It also has many uses. However, many people do not know its basic uses and what the preparation methods are. There is no way for everyone to appreciate a lot of related knowledge and deeper understanding. The following will introduce to you whether potassium hydroxide is harmful to the skin and whether it is really safe during use?

Basic Uses

In the inorganic industry, it is used as raw material for producing potassium salts such as potassium permanganate, potassium nitrite, and dipotassium hydrogen phosphate. In the daily chemical industry, it is used as raw material for making potassium soap, cleaning soap, shampoo soap, vanishing cream, cold cream, shampoo, etc. The pharmaceutical industry is used to manufacture raw materials such as progesterone and vanillin.

The dye industry is used to make melamine dyes. The battery industry is used to manufacture alkaline batteries. [4] It is used as a desiccant and absorbent in the manufacture of potassium soap, oxalic acid and various potassium salts. It is also used in electroplating, engraving, lithography, etc. It is mainly used as a raw material for the production of potassium salts, such as potassium permanganate and potassium carbonate.

In the pharmaceutical industry, it is used to produce potassium borohydride, spironolactone, serratol, progesterone and testosterone propionate, etc. In light industry, it is used to produce potassium soap, alkaline batteries, and cosmetics (such as cold cream, vanishing cream, and shampoo). In the dye industry, it is used to produce vat dyes, such as vat blue RSN, etc.

In the electrochemical industry, it is used for electroplating, engraving, etc. In the textile industry, it is used for printing and dyeing, bleaching and mercerizing, and is widely used as the main raw material for manufacturing artificial fibers and polyester fibers. In addition, it is also used as a metallurgical heating agent and leather degreasing. Basic chemical raw materials, used in medicine, daily chemicals, etc. ;Used as analytical reagent, saponification reagent, absorbent of carbon dioxide and water, and also used in the pharmaceutical industry.

Preparation method

Electrolysis

Potassium hydroxide can be produced by electrolysis of saturated potassium chloride solution, and the principle is the same as the electrolysis of saturated salt water.

2KCl+2H2O=electrolysis=2KOH+H2↑+Cl2↑[6]

Ancient Method

1. Produce calcium oxide by heating calcium carbonate at high temperature

CaCO?=high temperature=CaO+CO?

2. Calcium oxide reacts with water to form calcium hydroxide

CaO+H?O===Ca(OH)?

3. Calcium hydroxide reacts with wood ash to produce potassium hydroxide

Ca(OH)?+K?CO?===CaCO?↓+2KOH[6]

Storage method

Storage precautions: Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. The warehouse temperature shall not exceed 35°C and the relative humidity shall not exceed 80%. The packaging must be sealed and kept away from moisture. It should be stored separately from flammable materials, acids, etc. and should not be mixed. The storage area should be equipped with suitable materials to contain leaks.
