Precipitated calcium carbonate (PCC) is a fine, white, odorless powder used in the pharmaceutical industry as an excipient in many medications, supplements, and antacids. It's produced through a chemical reaction to create a high-purity calcium carbonate product that meets British Pharmacopoeia (BP) and United States Pharmacopeia (USP) standards for safety and quality.

PCC has many uses in pharmaceuticals, including:

• Calcium source: PCC can provide the body with calcium, which helps prevent osteoporosis and contributes to healthy bones. It's often used in calcium-based antacid tablets and liquids, and can also be used to formulate high dosage calcium supplements.
• Buffering agent: PCC can be used to buffer pH levels during the fermentation of antibiotics.
• Antacid: PCC can relieve heartburn and indigestion.
• Controlled release: PCC can help control the release of active ingredients in medications.
• Binding properties: PCC can enhance the binding properties of tablets. 

PCC also has low impurity content, high chemical stability, and exceptional bioavailability.

PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals. The most common arrangement for both precipitated and ground calcium carbonates is the hexagonal form known as calcite. A number of different calcite crystal forms are possible: scalenohedral, rhombohedral and prismatic. Less common is aragonite, which has a discrete or clustered needle orthorhombic crystal structure. Rare and generally unstable is the vaterite calcium carbonate mineral.

How Is Precipitated Calcium Carbonate (PCC) Made?

• Almost all PCC is made by direct carbonation of hydrated lime, known as the milk of lime process. The milk of lime process is simple in concept:

Mine high purity calcium carbonate rock:

• Crush the rocks to the particle size needed for processing – small stones or powder.

Separate some of the impurities from the crushed rock:

• Calcine (heat) in a kiln to 1850° F, which takes the calcium carbonate apart, forming lime (CaO) and carbon dioxide gas (CO2). The carbon dioxide can be captured for reuse. CaCO3 + Heat → CaO + CO2 ↑
• Add the lime to water to form calcium hydroxide (hydrated lime or slake).
• CaO + H2O → Ca(OH)2

Separate out additional impurities from the slaked lime:

• Combine the captured carbon dioxide with the slaked lime. Calcium carbonate reforms, and since it is insoluble in water, precipitates out.
• Ca(OH)2 + CO2 → CaCO3 ↓ + H2O

Separate additional impurities and grit from the PCC slurry:

• If the PCC is to be used in a paper mill or shipped to a latex paint plant, the lower solids slurry may be used as is, or processed to bring up the solids level, then tested before transfer or shipment.
• If the PCC is to be used as a dry product, the slurry is dewatered, dried, milled, packaged and tested.

Precipitated calcium carbonate (PCC) is a synthetic mineral that is widely used in various industries as a filler, pigment, coating agent, and extender. PCC is produced by precipitating calcium hydroxide and carbon dioxide in a controlled process, resulting in a fine, white powder with uniform particle size and shape. PCC has many advantages over natural calcium carbonate, such as higher brightness, whiteness, purity, and chemical stability.

Food grade PCC is a special type of PCC that meets the stringent requirements for food applications. Food grade PCC is safe, inert, and compatible with food ingredients and additives. Food grade PCC can be used to enhance the texture, appearance, flavor, and nutritional value of various food products, such as bakery, dairy, confectionery, beverages, and supplements. Food grade PCC can also improve the shelf life and stability of food products by acting as an anti-caking agent, moisture absorber, pH regulator, and buffering agent.

Our food grade PCC powder has the following specifications:

- Particle size: D50 = 2-3 microns, D97 = 10-15 microns
- Brightness: 95-98%
- Whiteness: 95-98%
- Purity: 98-99%
- Moisture: <0.5%
- pH: 9-10
- Heavy metals: <10 ppm
- Microbial count: <100 cfu/g

We offer food grade PCC powder in various grades and packaging options to suit different customer needs. We also provide customized solutions for specific applications and requirements. Our food grade PCC powder is certified by ISO 22000, HACCP, HALAL, KOSHER, and FSSAI. We guarantee the quality and consistency of our products and services.

RealChem Precipitated calcium carbonate (PCC) is a synthetic mineral that is widely used as a filler and coating pigment in the paint industry. PCC has several advantages over natural calcium carbonate (GCC), such as higher brightness, whiteness, opacity, and gloss. PCC also has a finer and more uniform particle size distribution, which enhances the dispersion and rheology of the paint.

PCC paint grade is a special type of PCC that meets the specific requirements of the paint industry. PCC paint grade has a high purity, low abrasiveness, and excellent compatibility with various binders and additives. PCC paint grade can improve the performance and durability of the paint, as well as reduce the cost and environmental impact.

Some of the specifications of PCC paint grade are:

- Brightness: 95% min
- Whiteness: 97% min
- Particle size: D50 0.7-1.2 microns, D97 3-5 microns
- Oil absorption: 20-30 g/100g
- pH: 9-10
- Moisture: 0.5% max
- Bulk density: 0.6-0.8 g/ml

Precipitated calcium carbonate (PCC) is a synthetic mineral that is used in toothpaste as a whitening agent and filler. It is also used in other oral care products and a wide variety of consumer products, such as cosmetics, plastics, and food supplements. 

PCC is used in toothpaste for a number of reasons, including:AbrasivePCC with 0.7 micron particles is an effective abrasive that helps remove plaque, staining, and other deposits from tooth enamel. 

ThickeningPCC with particles between 2 and 4 microns acts as a mild thickening agent. Cleaning and polishingPCC's smaller and more uniform particle size enhances the toothpaste's cleaning and polishing action. 

Binding and dispersionPCC's higher surface area and porosity improves the binding and dispersion of toothpaste ingredients.
 Viscosity
PCC can modify the toothpaste's viscosity, making it easier to squeeze and apply. CostPCC is less expensive than other dentifrice abrasives like silica and dicalcium phosphate. 

Precipitated Calcium Carbonate is the key ingredient in paan chuna, the white edible paste applied to betel leaves, where it serves as a source of calcium, aids digestion, and provides a traditional flavour. This calcium-rich substance is made from high-quality limestone and is processed to be edible, safe, and free from impurities for use in paan and other health-conscious applications. 

What it is and its purpose -

• A Source of Calcium:Chuna is an edible form of calcium, which contributes to bone strength and overall health when consumed in small quantities.
• Digestive Aid:Historically, chuna has been used for its digestive benefits, supporting gut health and aiding in calcium assimilation.
• Flavor and Texture:It provides a characteristic taste and texture that complements the other ingredients in paan.

How it's made and used

• Edible Quality:The calcium carbonate used in paan is specifically a high-grade, edible quality derived from natural limestone. 
• Processing:This limestone is finely graded and purified to create a white, paste-like consistency that is ready for use. 

• Application in Paan:A small amount of chuna paste is spread on the betel leaf, which is then filled with other ingredients like gulkand, elaichi, and supari for consumption.
