Product Overview
Citric Acid 25% Solution is a premium, pre-diluted aqueous formulation of citric acid designed specifically for direct industrial operations. This high-purity liquid solution completely eliminates the intensive operational steps required to dissolve solid crystalline citric acid, thereby preventing hazardous dust generation and ensuring immediate homogeneity within your chemical process streams. As an organic acid, citric acid serves as an exceptionally effective chelating agent, pH adjuster, and chemical intermediate across a wide spectrum of manufacturing sectors. Alliance Chemical distributes this precise formulation in multiple packaging configurations, ranging from convenient quarts to heavy-duty industrial drums and totes, ensuring we meet your facilities' specific procurement and handling requirements seamlessly.
The raw material utilized to manufacture this 25% aqueous solution has a molecular structure represented by the chemical formula C6H8O7, a molecular weight of 192.12, and is identified by CAS number 77-92-9. Providing a highly consistent 25% concentration allows facilities to completely bypass manual hydration and dilution processes, dramatically reducing labor costs while eliminating critical mixing and calculation errors. This pre-formulated liquid concentration is ideal for automated chemical dosing systems where precise volumetric control and predictable chemical behavior are required. For comprehensive quality assurance, a dedicated Certificate of Analysis (COA) is available upon request for every single manufacturing lot.
Why This Grade
Although no specific regulatory grade is defined — the grade is not applicable for this raw material stream — this industrial-strength 25% concentration offers significant processing and safety advantages over dry anhydrous alternatives. Handling dry citric acid crystals introduces substantial airborne dust hazards, which requires expensive air filtration systems and poses inhalation risks to floor operators. Furthermore, dry crystals are highly prone to caking and solidifying in humid storage environments, which complicates bulk handling. A stabilized liquid solution ensures a consistent density and viscosity, facilitating highly predictable, uninterrupted flow rates through industrial chemical dosing pumps without the risk of crystallization or line clogging.
Utilizing an incorrect chemical concentration or attempting to perform manual on-site dilution introduces severe failure modes in industrial processes. An under-concentration below the required 25% threshold can lead to inadequate pH adjustment, which fails to neutralize alkaline process streams and can ruin sensitive chemical batches. Conversely, attempting to handle over-concentrated solutions can lead to localized precipitation, forming solid citric acid crystals that block piping, damage pumps, and cause expensive unscheduled plant downtime. By relying on our standardized 25% solution, facilities maintain tight operational tolerances. Explore our acids collection to review alternative chemical options for your plant.

Hazmat & Shipping
Citric Acid 25% Solution is classified as a regulated hazardous material for transportation under Department of Transportation regulations. It is shipped under the United Nations identification number UN1760, hazard class 8 (Corrosive), and packing group III. The proper shipping name required for transit documents is Corrosive liquid n.o.s. (Citric acid). The designated GHS signal word for this material is WARNING. Because it is classified as a corrosive liquid, specialized transport protocols must be strictly followed, and Alliance Chemical ensures that all packaging and logistics comply fully with domestic and international hazmat regulations.
In strict compliance with GHS safety guidelines, handling this solution requires appropriate personal protective equipment (PPE) to protect operators. This liquid formulation carries the GHS hazard statements H319 (Causes serious eye irritation) and H335 (May cause respiratory irritation); there are no GHS pictograms associated with this specific hazard classification in the canonical data. Operators must wear chemical-resistant gloves, protective clothing, and eye protection as dictated by precautionary statement P280. If accidental exposure occurs, refer immediately to the precautionary statements such as P305+P351+P338 for eye contact. A detailed Safety Data Sheet (SDS) is provided with every order to support your facility's safety and regulatory compliance programs.
Handling & Storage
Proper storage of Citric Acid 25% Solution is necessary to maintain product stability and prevent equipment damage. Keep the chemical stored in a cool, dry, well-ventilated warehouse, ideally maintained within a temperature range of 50°F to 85°F to prevent any localized freezing or evaporation. Suitable storage container materials include high-density polyethylene (HDPE), polypropylene, and fiberglass-reinforced plastic (FRP). Avoid storing this acidic solution in carbon steel, copper, or aluminum vessels, as the corrosive nature of the acid can react with these metals to generate hydrogen gas. Keep containers tightly closed when not in use, and store away from incompatible materials such as strong bases, strong oxidizing agents, and metal nitrates.
