Basic Information:

Oxalic acid, also known as oxalic acid, is widely found in plant-source foods.Oxalic acid is a colorless columnar crystal, easily soluble in water and insoluble in organic solvents such as ether. Oxalate root has a strong coordination effect and is another type of plant-source food.Metal chelating agent.When oxalic acid is combined with some alkaline earth metal elements, its solubility is greatly reduced, such asCalcium oxalicateAlmost insoluble in water.Therefore, the presence of oxalic acid has a great impact on the bioavailability of essential minerals; when oxalic acid is combined with sometransition metalWhen the elements are combined, a soluble form is formed due to the coordination of oxalic acid.complex, its solubility is greatly increased.

Oxalic acidIt begins to sublimate at 100°C, sublimates rapidly at 125°C, sublimates heavily at 157°C, and begins to decompose.Can react with alkali, esterification can occur,Nicheation and amidation reactions.Reduction reactions can also occur, which occur when heateddecarboxylation reaction.Aquatic oxalic acidYesHygroscopic.Oxalic acid can form water-soluble metals with many metalsCompatrion.

Instructions:

Oxalic acid has a certain degree of toxicity. Try not to come into direct contact with the skin. It is best to wear gloves when cleaning.

   1. Direct use: Apply an appropriate amount of oxalic acid powder to the area that needs to be cleaned, and then clean it with a rag dipped in water.

   2. Blend into oxalic acid solution for use.Be careful to use hot water for blending. The hotter the water, the better the blending effect. You can also directly blend with boiling water.The mass ratio of oxalic acid and hot water is 15~25g oxalic acid added to 100g water for blending. This concentration is enough for ordinary stains.If the stain is particularly strong, you can add more oxalic acid (but oxalic acid is toxic, so it is not recommended to add too much).

   3. After the oxalic acid solution is blended, use a rag to dip the oxalic acid solution into the stained area.Or put the solution into a small spray bottle and spray it wherever there are stains. After spraying stubborn stains, wait for a while and then wipe with a rag.

   4. After wiping, clean the wiped area again with clean water.The purpose of this is to prevent skin from coming into contact with residual oxalic acid solution, making it safer.

Things to note:

   1. Please test a sample before use and adjust to the appropriate concentration according to the actual situation before use.

   2. Avoid contact with skin and clothing. Please wear rubber gloves and other protective equipment when using.

   3. Do not enter eyes, do not take orally, and keep away from children.

   4. In case of accident, rinse immediately with clean water and seek medical treatment if necessary.
