Benefits of calcium carbonate cas number 471 34 1
alcium carbonate particles, available in various sizes (from micron to nanoscale) and forms, offer a range of benefits across industries, from healthcare to manufacturing. Here’s a breakdown of their key advantages:
1. High Calcium Content for Nutritional & Pharmaceutical Use
Premium Calcium Supplement: As a primary ingredient in dietary calcium supplements, calcium carbonate particles provide the highest elemental calcium content (40% by weight), making them an efficient choice for addressing calcium deficiencies. This is critical for bone health, muscle function, and nerve transmission, especially for populations at risk of osteoporosis (e.g., postmenopausal women, older adults).
Antacid Action: In medicinal formulations, fine calcium carbonate particles neutralize excess stomach acid, relieving heartburn, indigestion, and acid reflux. Their large surface area (in micronized form) ensures rapid reaction with gastric acid for fast-acting relief.
2. Versatile Industrial Filler & Reinforcing Agent
Enhanced Material Properties: In plastics, rubber, and polymers, calcium carbonate particles act as fillers to improve mechanical properties (e.g., tensile strength, hardness, impact resistance) while reducing production costs. Their inert nature ensures compatibility with most matrices, making them ideal for products like pipes, automotive parts, and packaging.
Texture & Stability in Coatings/Adhesives: In paints, coatings, and adhesives, these particles enhance opacity, thickness, and surface smoothness. They also improve resistance to weathering and UV degradation, extending the lifespan of industrial and decorative finishes.
3. Controlled Particle Size for Targeted Applications
Nanoscale Particles for Advanced Uses: Nano-calcium carbonate offers unique properties, such as increased surface area and reactivity, making it valuable in:
Drug Delivery Systems: Encapsulating medications for targeted release or enhanced bioavailability.
Cosmetics: As an additive in sunscreens (UV scattering) or creams (texture improvement), with nano-sized particles ensuring seamless application without chalkiness.
Micronized Particles for Food & Agriculture: In food products, micronized calcium carbonate serves as a fortifier (e.g., in flours, juices) and anti-caking agent. In agriculture, it adjusts soil pH and provides calcium to plants, improving crop health and yield.
4. Environmental & Sustainability Benefits
Carbon Capture & Storage (CCS): Calcium carbonate particles are used in industrial processes to absorb CO₂, such as in flue gas desulfurization (FGD) systems to reduce sulfur emissions from power plants. They also play a role in mineral carbonation, a method to permanently store CO₂ as stable carbonates.
Biodegradable Composite Support: In eco-friendly materials, calcium carbonate fillers enhance the biodegradability of plastics by promoting fragmentation and microbial assimilation, reducing environmental waste.
5. Cost-Effective & Abundant Natural Resource
Economical Production: Derived from limestone, marble, or chalk—abundant natural sources—calcium carbonate particles are cost-effective to mine, process, and modify for various applications. This affordability makes them a preferred choice across industries, from low-cost supplements to high-volume industrial materials.
Regulatory Safety: Widely recognized as safe (GRAS) by regulatory bodies (e.g., FDA, EFSA) for use in food, pharmaceuticals, and consumer products, ensuring compliance and consumer trust.
6. Precision in Medical & Dental Applications
Bone Graft Substitutes: In orthopedics, porous calcium carbonate particles (e.g., synthetic coral-like structures) act as scaffolds for new bone tissue growth, promoting osseointegration in joint replacements or spinal fusion surgeries.
Dental Fillings & Whitening: Fine particles are used in toothpaste as an abrasive to remove stains gently while providing calcium to remineralize enamel, supporting oral health.
Calcium carbonate particles stand out for their adaptability, combining high calcium potency in healthcare with mechanical and functional enhancements in industry, all while offering environmental and cost advantages. Their versatility across scales and sectors makes them an indispensable ingredient in modern manufacturing and wellness.
APPLICATIONS
CALCIUM CARBONATE PARTICLES: A KEY INGREDIENT IN FOOD FORTIFICATION
Dense Calcium Source: With the highest elemental calcium content of any supplement (40% by weight), calcium carbonate particles deliver a concentrated dose of this essential mineral. This makes them ideal for fortifying foods to meet daily recommended intakes (e.g., 1,000–1,300 mg/day for adults), especially for populations at risk of deficiency—such as vegetarians, older adults, or those with limited dairy intake.
Acid-Activated Absorption: In the stomach, calcium carbonate reacts with gastric acid to release ionic calcium, which is readily absorbed in the intestines. While its absorption efficiency is slightly lower than organic calcium forms (e.g., citrate), its sheer calcium density makes it a cost-effective choice for large-scale fortification, ensuring meaningful calcium delivery when paired with vitamin D (which enhances uptake).
