Carrageenan (E407)

Description

1. Product Overview

Carrageenan (E407) is a high-performance, seaweed-derived hydrocolloid used as a stabilizer, gelling agent, and thickener in industrial formulations. Primarily sourced from red algae (Kappaphycus and Eucheuma species), it delivers reliable rheology control across food, pharmaceutical, personal care, and technical applications. Its key value proposition is predictable viscosity and gel strength at commercial scale, enabling formulators to reduce variability, extend product shelf life, and simplify process control. Strategically, Carrageenan (E407) is a critical ingredient for manufacturers seeking scalable, cost-effective structuring and stabilization solutions that meet regulatory and supply-chain expectations.

2. Key Specifications & Technical Characteristics

• Chemical composition: Polysaccharide family of sulfated galactans (kappa, iota, lambda fractions present depending on grade).

• Functional groups: Sulfate esters and 3,6-anhydro-D-galactose units (typical of carrageenan types).

• Purity/grade: Food-grade E407; pharmaceutical and technical grades available on request (specify batch certificate).

• Active content: Total polysaccharide content typically ≥ 85–95% depending on grade and processing.

• Moisture content: Typical 12–16% (adjustable per specification).

• Ash content: Typical 5–12% (grade-dependent).

• Sulfate content: Varies by type; kappa ~20–30% (typical range), iota/lambda accordingly—certificate of analysis provided per shipment.

• Physical form: Powder or coarse flake options.

• Color: Cream to off-white.

• Particle size: Standard powder mesh range (e.g., 80–200 mesh) or flakes size options; custom milling available.

• Bulk density: Approximately 0.3–0.6 g/mL (packed density dependent on form).

• Solubility/processing: Soluble/swellable in hot or cold water depending on type and formulation; forms firm gels (kappa), elastic gels (iota), or thickening dispersions (lambda).

• pH stability: Functional between pH 3–10; performance varies with cations and co-ingredients.

• Temperature stability: Gelation and viscosity profiles optimized for industrial thermal processing; specifics provided in technical data sheet.

• Packaging options: 25 kg multi-ply kraft bags with inner PE liner; 500–1,000 kg bulk bags (FIBC); ISO tank-compatible slurry supply on request.

• Shelf life: 24 months under recommended storage (cool, dry, <40% RH) when unopened; storage and handling guidance on TDS/MSDS.

3. Core Industrial Applications

• Food & Beverage: Stabilizer and gelling agent in dairy (chocolate milk, desserts), meat processing (binding, moisture retention), confectionery (gummies, jellies), and plant-based alternatives (texture structuring). Offers consistent mouthfeel and synergies with proteins and polysaccharides.

• Pharmaceuticals & Nutraceuticals: Excipient for controlled-release matrices, capsule and suspension stabilizer, and viscosity modifier in topical formulations. Meets stringent quality documentation for regulatory submissions when pharmaceutical grade is supplied.

• Personal Care & Cosmetics: Rheology control in creams, lotions, shampoos, and hydrogel masks. Enhances emulsion stability, sensory profile, and product yield.

• Industrial & Technical: Used in drilling fluids, fire retardants, adhesives, and textile printing pastes for tailored viscosity and film properties. Robust performance under shear and temperature variations.

• Why it outperforms alternatives: Carrageenan provides a unique combination of gel strength, thermo-reversibility, and compatibility with salts and proteins where many synthetic thickeners fail; it often allows lower usage levels to achieve target rheology, reducing material costs and formulation complexity.

4. Competitive Advantages

• Quality consistency: Manufactured under ISO-aligned controls with lot-to-lot certificate of analysis ensuring predictable functional performance.

• Supply reliability: Secured raw-material sourcing and long-term contracts with coastal harvesters plus safety stock buffers to support continuous industrial supply.

• Logistics capability: Flexible packaging and bulk handling, FOB/CIF shipments, experienced export documentation, and regional distribution hubs for expedited replenishment.

• Price competitiveness: Economies of scale and optimized processing deliver competitive unit pricing for large-volume buyers; tailored pricing tiers for contract volumes.

• Sustainability: Responsibly sourced seaweed with traceability options; options for certified sustainable harvests and lower-carbon transport solutions available on request.

• Technical support: Dedicated technical service with formulation guidance, rheology profiling, TDS/MSDS, COA per lot, and on-request lab trials and scale-up assistance.

• Regulatory support: Documentation to support food-grade regulatory compliance (E-number labeling), and provision of allergen, heavy metals, and microbiological test results.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT.

• Loading capacity (per container): Typical loading capacities — 20-foot container: up to 20 MT (bagged, depending on palletization and packaging); 40-foot container: up to 24–25 MT (FIBC optimization may increase capacity). Specific loading plan provided per order.

• Lead times: Standard lead time and production scheduling provided upon inquiry; expedited production available for contracted volumes.

• Terms: Supply agreements available with volume-based pricing, quality guarantees, and logistics terms to suit global B2B procurement.
