Physical and Chemical Properties:

Ammonium hydroxide, also called Aqua Ammonia, solution of ammonia gas in water, a common commercial form of ammonia. It is a colourless liquid with a strong characteristic odour. In concentrated form, ammonium hydroxide can cause burns on contact with the skin; ordinary household ammonia, used as a cleanser, is dilute ammonium hydroxide.

Ammonium hydroxide is used in quite a few manufacturing processes too, including fertilizer and plastic and rubber production. One of the key ingredients of fertilizers is nitrogen, which can be derived from ammonium hydroxide (it's the N in the (NH4)OH). It can also be used to stain wood that contains tannic acids and synthesize chemicals like sodium carbonate.

Ammonium hydroxide may also be used as a neutralizer during processes that involve acidic chemicals. Its high alkalinity, however, also makes it very corrosive to certain metals, including aluminum, making it useful in industries like circuit board manufacturing, as companies can use it to etch circuit boards by corroding the metal away in a specific pattern.


Ammonium Hydroxide should be stored in a closed container and kept cool, otherwise, the ammonia gas will come out of solution and the material strength will be reduced.


Our chemicals can be tested by any impartial third party, such as SGS,BV,ISO,CE, etc.
