Product Description
Calcium Hydrogen Phosphate is an inorganic calcium phosphate commonly known as Dicalcium Phosphate, Dibasic Calcium Phosphate or DCP. It is supplied as a white powder or granule in anhydrous and dihydrate forms.
Depending on its grade and specification, DCP may be used as a calcium and phosphorus source, food-processing ingredient, feed material, pharmaceutical excipient or functional mineral ingredient.
Food, feed and pharmaceutical applications require the appropriate regulated grade. One grade should not be assumed suitable for every application.

The order specification, product label and Certificate of Analysis should clearly identify the required hydration form.
Calcium Hydrogen Phosphate is inorganic. It consists of calcium ions and hydrogen phosphate ions and contains no carbon-based organic structure.
Commercially, it is generally classified as an inorganic phosphate, functional mineral ingredient or fine inorganic chemical. It is supplied as a finished ingredient rather than a chemical synthesis intermediate.
Anhydrous DCP contains no crystallization water. It may be selected where lower loss on drying, controlled mineral content or specific formulation behavior is required.
DCP dihydrate contains two molecules of crystallization water. Its molecular weight and drying-loss specification differ from those of the anhydrous form.
The two forms should not be substituted solely on an equal-weight basis without reviewing the formulation and elemental calcium and phosphorus contribution.
Common grades include:
Food grade
Feed grade
Pharmaceutical or excipient grade
Oral-care grade
Industrial grade
Reagent grade
The required regulatory standard and application must be confirmed before quotation. Food-grade approval does not automatically establish pharmaceutical or feed compliance.
Specification | Purchasing Importance |
Hydration form | Distinguishes anhydrous DCP from DCP dihydrate |
Assay | Confirms calcium hydrogen phosphate content |
Calcium content | Important for mineral and feed formulations |
Phosphorus content | Critical for feed and nutritional formulations |
Loss on drying or ignition | Helps verify hydration and moisture |
Fluoride | Important for food and feed grades |
Arsenic and lead | Required for regulated applications |
Acid-insoluble matter | Indicates unwanted insoluble material |
Particle size | Influences blending, flow and processing |
Bulk density | Affects packaging and formulation handling |
Microbiological limits | May be required for food or pharmaceutical grades |
The contractual specification and COA should identify the hydration form, analytical method and applicable standard.
Approved food-grade DCP may be used as a dough conditioner, yeast food, mineral ingredient or processing aid where permitted by local regulations.
Feed-grade DCP provides calcium and phosphorus in compound feed, mineral premixes and feed concentrates. Buyers should confirm phosphorus, calcium, fluoride, moisture and particle-size requirements.
A suitable pharmacopeial or excipient grade may be used as a formulation excipient or mineral source. Compliance with the required pharmacopeia and manufacturing standard must be verified.
Selected grades may be used in oral-care formulations and other technical applications where controlled particle size, abrasiveness and purity are required.
Application suitability depends on the exact grade and should be evaluated in the customer’s formulation.
Before requesting a quotation, provide:
Required anhydrous or dihydrate form
Food, feed, pharmaceutical or industrial application
Required standard or specification
Calcium and phosphorus limits
Fluoride and heavy-metal limits
Powder or granular form
Required particle-size range
Packaging, quantity and destination
A representative sample should be evaluated before commercial production when particle size, flowability or formulation performance is important.
Calcium Hydrogen Phosphate is commonly supplied in moisture-resistant bags with an inner liner. Exact packaging depends on product grade, order quantity and destination.
Store it in a clean, dry and ventilated location. Keep bags sealed and protect the product from moisture, contamination and incompatible materials.
Avoid generating or breathing dust. Wear suitable eye protection, gloves and respiratory protection when workplace exposure conditions require them. Follow the current Safety Data Sheet.

Food, feed and industrial specification matching
Powder or granular product options
COA, SDS and technical-document support
Sample evaluation
Export packaging and logistics coordination
Pre-shipment quality verification
Regulatory status, certification and specification limits should be confirmed for the exact grade and production source before purchase.
Yes. Calcium Hydrogen Phosphate, Dicalcium Phosphate and Dibasic Calcium Phosphate are commonly used names for DCP.
They contain the same calcium hydrogen phosphate component but have different water content, molecular weight and drying-loss specifications. The required form must be stated on the order.
No. Food-grade material must comply with the applicable food-additive standard and impurity limits. Industrial or feed grades should not automatically be used in food.
Specify the hydration form, grade, standard, particle size, quantity, packaging and destination. For feed applications, also provide the required calcium, phosphorus and fluoride limits.
Contact AOZUN with your required DCP form, grade, specification, particle size, order quantity and delivery destination.
