A major application of phosphonates is in treatment of cooling and boiler water systems as scale inhibitors. In particular, for ATMP and its sodium salts, prevention of the formation of calcium carbonate scale.

Phosphonates of this type are also used to prevent scale formation in "squeeze" applications in off‐shore oilfield use.

Phosphonates are used as stabilizers for peroxides, particularly in pulp bleaching in paper industry or in the scouring and bleaching processes of textile industry. Phosphonates of this category are used in consumer detergent applications as additives to provide a range of properties such as anti‐redeposition and soil dispersion or as perborate and percarbonate stabilizers preventing decomposition by transition metals. These substances act as a chelating agent and hydrogen

peroxide stabilisers in personal care products such as bar soaps and hair care preparations. Further uses in specific industrial and professional detergent formulations may be found in hard surface cleaning, vehicle washing and dairy cleaning.

The substances are also dispersant and scale inhibiting agent in some agricultural fertilizer preparations.

They may be used also as a dispersant and viscosity conditioner in coatings and in ceramics slurry, they will be degraded in case of high temperature process. Phosphonates can be used as chelating agent in weaving and dyeing industries and as metal surface treatment agent.
