What is Ammonia Solution?

Ammonium hydroxide (Ammonium Hydroxide) usually refers to a solution formed by ammonia (NH3) dissolved in water. Its chemical formula can be written as NH3·H2O or NH4OH.

Ammonium hydroxide actually exists in the form of monohydrated ammonia (NH3·H2O) in aqueous solution. This is because ammonia (NH3) will partially ionize in water to form ammonium ions (NH4+) and hydroxide ions (OH-), but most of the ammonia molecules still exist in molecular form and form monohydrated ammonia with water molecules.
Chemical equilibrium equation: NH3 + H2O ⇌ NH4+ + OH-

Ammonia Solution Uses

  1. Agriculture and Fertilizer Industry
    Ammonia Solution is an important raw material for the manufacture of nitrogen fertilizers, such as urea, ammonium nitrate and ammonium phosphate. Nitrogen is an essential nutrient for plant growth, and ammonia water can promote crop growth as a nitrogen source.
    In agriculture, ammonia water can be directly applied to the soil to provide a quick-acting nitrogen source and increase crop yields.
  2. Chemical Production
    Ammonia Solution is used to produce a variety of chemicals, including plastics, synthetic fibers, rubber, dyes, coatings and explosives.
    It plays a key role in the preparation of inorganic salts, such as ammonium sulfate, ammonium chloride and other ammonium salts.
    In fine chemicals, ammonia water participates in organic synthesis reactions as an aminating agent and is used to produce pharmaceutical intermediates and other organic compounds.
  3. Pharmaceutical Industry
    Ammonia Solution is used as a raw material or reaction medium in the pharmaceutical process and participates in the synthesis and refining of drugs.
    As a weak base, ammonia water is used to adjust the pH value and affect the stability and activity of drugs.
    The synthesis of some drugs requires ammonia water as an aminating agent or reducing agent.
  4. Metal Processing and Cleaning
    Ammonia Solution is used for metal surface treatment, such as removing oxide layers, grease and rust from metal surfaces.
    In the electroplating industry, ammonia is used as a complexing agent to help control the solubility and stability of metal ions.
  5. Wastewater Treatment
    Ammonia Solution can be used to adjust the pH of wastewater and neutralize acidic wastewater to make it suitable for further treatment or discharge.
    During wastewater treatment, ammonia helps precipitate heavy metal ions and reduce pollution.
  6. Electronics and Semiconductor Industry
    Ammonia Solution is used in the electronics industry to prepare circuit boards because it can clean and activate metal surfaces.
    In semiconductor manufacturing, ammonia is used in the cleaning and etching processes of wafers.
  7. Laboratory and Research
    Ammonia Solution is often used as a weak base in chemical experiments and participates in a variety of chemical reactions.
    As an analytical reagent, it is used for qualitative and quantitative analysis, such as determining the concentration of acids in titration analysis.
  8. Cleaning Products
    Ammonia Solution is an ingredient in many household and industrial cleaners used to clean glass, metal and hard surfaces.
    Its alkalinity can help break down oil stains and dirt.
  9. Military and Special Applications
    Ammonia Solution is an alkaline disinfectant that can be used in the military to neutralize certain chemical weapons, such as sarin nerve agent.
    In some special industrial processes, ammonia is used as a catalyst or reaction medium.

Ammonia Solution's Prominent Applications in Cosmetics

pH Regulator:
Ammonia Solution is a weak base that can neutralize acidic ingredients and help adjust the pH value of cosmetics to the appropriate range to match the physiological conditions of the skin. The pH value of human skin is usually between 4.5 and 5.5.
pH adjustment is essential to ensure product stability and safety, as an inappropriate pH value may cause product deterioration or irritation to the skin.

Perm Agent:
In hair products, especially perms and hair dyes, Ammonia Solution can open the cuticle of the hair, making it easier for dye molecules to penetrate into the hair shaft, thereby achieving a lasting dyeing effect.
It can also help control the reaction rate during chemical perms to ensure uniform and lasting curling effects.

Emulsifiers and Dispersants:
Although Ammonia Solution itself is not an emulsifier, it can enhance the efficiency of emulsifiers by adjusting the pH value of the system and help the oil and water phases mix more stably.
It can also act as a dispersant to help solid particles be evenly distributed in the liquid medium to prevent agglomeration and precipitation.

Preservative function:
The weak alkaline environment of Ammonia Solution is not conducive to the growth of microorganisms, so it can indirectly play a preservative role and extend the shelf life of the product.

Neutralization of ingredients:
In some cases, Ammonia Solution can neutralize the strong acidic ingredients in the formula, such as fruit acid or salicylic acid, to reduce their irritation to the skin.

Cleansing products:
In cleaning products, such as cleansers and makeup removers, Ammonia Solution can enhance the cleaning ability while adjusting the pH value to make the product more gentle.

Exfoliating and whitening products:
Ammonia Solution can help remove dead skin cells and promote skin renewal. It is sometimes used in whitening products to accelerate the removal of pigmentation.
