Uses & applications

Versatile performance across industries.

Food & beverage

Certified food-grade material is used as an acidulant, pH regulator, flavouring aid, chelating agent and formulation ingredient.

Cleaning & descaling

Used in controlled formulations to remove compatible mineral and scale deposits from process equipment and surfaces.

Water treatment

Used in selected pH-adjustment, chelation, cleaning and scale-removal processes after suitable process review.

Stainless-steel passivation

Used in standard-controlled citric-acid treatments for clean stainless-steel surfaces where applicable.

Cosmetics & personal care

Suitable certified grades are used for pH adjustment in shampoos, creams, gels, lotions and related formulations.

Detergents & chemicals

Used in cleaning, detergent and chemical formulations for acidity, chelation and mineral-deposit control.

Stainless-steel passivation

Apply an appropriate standard.

ASTM A967/A967M includes immersion treatment using citric-acid solution as one option for chemical passivation of stainless-steel parts.

Process qualification is required. Formulation, temperature, exposure time, pre-cleaning, rinsing, neutralisation and acceptance testing must be established for the stainless-steel grade and applicable standard.

Descaling is not the same as passivation

Cleaning, descaling and passivation have different objectives. Confirm the required surface condition, standard, chemistry and verification method before selecting a treatment programme.

Grade & certification

Use the correct grade for regulated applications.

Only appropriately certified food, pharmaceutical or cosmetic material should be used for regulated applications. Confirm the required grade, purity, applicable specification, traceability, Certificate of Analysis and packaging before ordering.
