The purity percentage of potassium hydroxide is given in this article.Potassium hydroxide is an inorganic compound also known as caustic potassium. It has the chemical formula koh. There are hundreds of different uses for potassium hydroxide. It is used as an additive in commercially processed foods. Great for chemical peels of fruits and vegetables. It can also be found in chocolate and cocoa processing, soft drink processing and ice cream thickening. Potassium hydroxide is present in other items such as liquid soaps, lotions, shampoos, varnishes and toothpastes.Potassium hydroxide is an excellent pH regulator for soils with high acidity. Pharmaceutical, veterinary, paper production, chemical production and oil refining are other industries that use potassium hydroxide. Our potassium hydroxide is nutritionally safe.
Purity The amount of product that results from a reaction is called purity.If it has a factory that produces medical drugs, product efficiency will still be important, but the purity of the product may be even more important. This is because impurities can harm people who take these drugs.
NaOH and KOH are strong desiccants, meaning they absorb water easily and quickly from the air.
Soap makers often assume the percentage of alkaline purity of potassium hydroxide and NaOH in their soap mix, which is what the distributor says. Even if the purity is high when buying alkali, over time, the purity can decrease slightly.NaOH (potassium hydroxide KOH) does not break down over time. Exposure to water and carbon dioxide (CO2) in the air also affects it. If you can protect an alkali properly, you can If you do not protect it from water and CO2 (or other things it wants to react with), it will lose a lot of purity within hours or days.When NaOH or KOH absorbs water from the air, it gains water weight. One gram of NaOH due to water absorption is not one gram of pure NaOH. Some of this weight of water will be useless.When NaOH or KOH also absorbs CO2 from the air, NaOH reacts with CO2 to form sodium carbonate (baking soda) and KOH reacts with CO2 to form potassium carbonate. Carbonates are alkaline chemicals but do not react easily with fats to make soap. One gram of NaOH contaminated with sodium carbonate is not one gram of pure NaOH.The mere fact that NaOH or KOH is pure does not mean that it should not be used in soap making. But how do we know what purity really is? The best way is to test true purity. Otherwise we are basically guessing that when we have a number for purity, this information can be used to regulate the weight of alkali, so real alkali is used enough to make good soap this is a Applications of potassium hydroxide.
So what can be done to keep NaOH and KOH as pure as possible? A “dry bin” is a home storage method that works well to protect NaOH or KOH.Smaller containers are airborne and NaOH and KOH are placed in a strong 5 or 7 gallon plastic bucket. A commercial desiccant (water-absorbing chemical) is added to the large outer bucket to remove moisture from the air around smaller alkaline containers. The bucket is tightly covered with the main tightly closed lid or the “gamma” screw lid.
A dry bucket has other important benefits. In the event of a leak in a NaOH or KOH storage container, this leak will spill into a large bin and is not dangerous to children or pets.Important: Do not expose the desiccant to direct contact with NaOH or KOH. The desiccant should be placed in a larger dry bucket outside the alkaline container. If placed directly with alkali, it will not work properly.
NaOH or KOH itself is a strong desiccant. Much stronger than safe chemicals that are sold as desiccants such as silica gel, calcium sulfate, calcium chloride and so on.If NaOH accumulates in a space, it absorbs any water from the commercial dryer and also absorbs water vapor in the space. The “formal” desiccant will never work as long as it is in the same NaOH or KOH atmosphere.
