Citric Acid Monohydrate

Gandi Chemical Solutions supplies Citric Acid Monohydrate (CAS 5949-29-1) to mines, concentrators and mineral processing plants. It is supplied as food grade. Packaging: 25kg bag. Priced by quotation, with a current safety data sheet on every consignment.

Citric acid monohydrate is a naturally derived organic acid supplied here at food grade, making it suitable for both industrial processing and applications with stricter purity requirements. It arrives as white to translucent crystals or powder that dissolve readily in water, giving a mildly acidic solution useful for descaling, metal cleaning, pH adjustment, and as a chelating agent in water treatment. Handlers should still avoid prolonged eye contact, as concentrated solutions can cause irritation. Store in a dry area since the monohydrate form is prone to caking if exposed to moisture.

Where citric acid monohydrate is used

• Acidulant and flavour adjustment in food and beverage production
• Chelating agent for metal ions in cleaning and descaling formulations
• Boiler and membrane cleaning, where it lifts scale without chloride attack
• pH buffering in cosmetics, detergents and household products
• Sequestrant in electroplating and metal-finishing baths

Key features

• Food grade grade. Colourless, white or translucent crystals or powder.
• CAS 5949-29-1, C6H8O7.H2O.
• Also ordered as Acidum citricum monohydrate, Citiric acid, Soothe Chewable.
• Supplied in 25kg bag, with larger units quoted on request.
• Classified Warning (H319). Current SDS ships with every consignment.

Specification and grade

Food-grade citric acid monohydrate, CAS 5949-29-1, supplied as colourless to white crystals or powder. Bulk density is around 900 kg/m³ at 20°C and a 50 g/L solution sits at pH 1.8. The monohydrate carries one water of crystallisation, so dose calculations written for the anhydrous form need adjusting by roughly 8.6%.

Handling and storage

Classified H319 — causes serious eye irritation — signal word Warning. The practical storage risk is caking: citric acid monohydrate picks up moisture and sets solid in a humid store. Keep bags sealed, off the floor and away from steam lines. Goggles and gloves are enough for normal handling; dust control matters more than corrosion protection here.

Packaging and supply

Standard pack is a 25kg bag. Because this is a food grade, each consignment ships with a certificate of analysis and the safety data sheet, and we can supply allergen and GMO declarations on request — ask for them with the quotation rather than after delivery.
