Monoammonium phosphate (MAP) (also known as ammonium dihydrophosphate or monobasic ammonium phosphate) is an inorganic compound with the formula NH4H2PO4.

In horticulture, MAP provides the soil with nitrogen and phosphorus elements in a form suitable for plants. Its NPK label is 12-62-0 with 12% elemental nitrogen and (nominally) 62% phosphorus pentoxide P2O5 or 27% elemental phosphorus. MAP is often used as a source of nutrients in greenhouses and hydroponics. In addition to being an efficient source of phosphorus, ADP helps plants to absorb phosphorus naturally present in the soil. This is due to the presence of ammonium (NH4+), which improves the availability of phosphorus, while the presence of hydrogen ions (H+) lowers the pH in the root zone and also promotes phosphorus uptake. Ammonium dihydrogen phosphate is recommended at the beginning of the growing season, when phosphorus availability is essential for root formation. MAP can be mixed with other fertilisers to meet the nutritional needs of plants throughout the growth cycle. Suitable for the preparation of fertiliser mixtures and liquid fertilisers. MAP should not be mixed with calcium or magnesium fertilisers as insoluble magnesium/calcium phosphates are formed. Fertilisation is used to accelerate flower formation and flowering. High phosphorus content intensifies flower colour. It is advisable to start fertilising with monoammonium phosphate when the first flower buds appear. It is also recommended for high-sugar fruit trees at the time of fruiting to increase the sugar content and improve fruit quality. Fertilisation by irrigation: 1-2% solution for most plants. Foliar fertilisation: fertilise every 8-10 days with a 0.2% solution (20g/10l water). For strawberries, flowers, apple trees, pears, foliar fertilisation at a concentration of 0,1-0,2% (10-20g/10l water). For tomatoes, 0,3% (30g/10l of water) foliar concentration. For shrubs, 0,2% (20g/10l of water). MAP is compatible with most pesticides and fertilisers used. Iron, manganese, zinc and copper must be in the form of chelates, otherwise insoluble compounds may form.

In cosmetics, ammonium dihydrogen phosphate is used in skin care products to adjust and maintain (buffer) the pH of the formula, keeping it acidic (pH ~ 4-5). This component is found naturally in the human body, where it is used for cell and tissue repair and growth, and was therefore considered safe for use in cosmetics. It is used as an emulsifier, emulsion stabiliser, thickener and penetration enhancer. Ammonium dihydrogen phosphate improves the level of adsorption of the other ingredients and prolongs their action. It is also used as a preservative enhancer, which is particularly effective in the combination of fatty acids used in creams, moisturising oils and masks. Its functions (INCI)

  • pH regulator: stabilises the pH of cosmetics
  • Oral care/hygiene product: Provides a cosmetic effect on the oral cavity (cleansing, deodorising and protecting)

In the cleaning industry,monoammonium phosphate is used both as a main ingredient and as an auxiliary ingredient. A 1% solution gives a pH of 4.0-4.7, i.e. a mildly acidic solution capable of reacting with calcareous soils, and can therefore be used to clean a wide range of surfaces that are resistant to acidic media. MAP is used as a buffer to prevent strong pH fluctuations. Its properties are of great use in the manufacture of detergents as it bleaches fabrics, refreshes colours thanks to the properties of monoammonium phosphate, and at the same time does not damage the structure of the fabrics, as the natural fibres (cotton, wool, etc.) are resistant to acidic media.

In extinguishing systems,ammonium dihydrogen phosphate is used as a constituent of some dry chemical extinguishers ABC powder. This compound absorbs a large amount of heat, thus lowering the combustion temperature, while at the same time forming a fluffy, non-combustible phosphate layer and thus inhibiting the combustion process. MAP can be found in wood flame retardants in combination with other components, where at higher temperatures it starts to form a non-combustible and oxygen-impermeable porous crystalline layer which increases the ignition temperature of the wood and thus protects it from ignition.

In animal husbandry, amophos is used as a feed additive. The H4 ion is synthesised and converted into proteins, while the H2POion also supports many metabolic processes in animals and is used to maintain the body's electrolyte balance and the structure of DNA.

In metalworking, MAP is used for mild acid cleaning and to provide anticorrosive protection as the solution has a pH of 4,0-4,7. These properties are important when machining metals with different types of patinas.

MAP is used in school experiments because it is relatively non-toxic and is also a popular material for recreational crystal growing, sold as toy kits mixed with different coloured paints.

In biotechnology, MAP is also used for yeast fermentation. It can be used in a wide range of processes: brewing, wine fermentation, production of active pharmaceutical ingredients by fermentation, etc.
