Comprehensive Guide to Sodium Alginate CAS No 9005-38-3: Properties, Uses, and Sourcing Essentials
Sodium Alginate, identified by CAS No 9005-38-3, is a naturally derived polysaccharide extracted from brown seaweed (algae) such as Laminaria digitata and Ascophyllum nodosum. This versatile hydrocolloid has become indispensable in food manufacturing, pharmaceuticals, and industrial applications due to its unique gelling, thickening, and stabilizing properties. Chemically, it is the sodium salt of alginic acid, a linear copolymer of β-D-mannuronic acid (M) and α-L-guluronic acid (G) units, with molecular weights typically ranging from 10,000 to 600,000 Daltons.
In the context of buying CAS No 9005-38-3 for your USA-based operations, understanding its structural nuances is key. The ratio of M to G blocks determines its functionality: high-G alginates form rigid, brittle gels ideal for encapsulation, while high-M variants provide elastic, smooth textures perfect for dairy products. Our Sodium Alginate CAS No 9005-38-3 is sourced from premium North Atlantic kelp, processed through advanced alkaline extraction, purification, and spray-drying to achieve 99% purity with low heavy metals (<10 ppm lead).
Historically, Sodium Alginate CAS No 9005-38-3 gained prominence in the 1940s during WWII for textile printing but exploded in food use post-1950s with FDA approval as GRAS (Generally Recognized as Safe). Today, global demand exceeds 50,000 metric tons annually (Statista 2025 forecast), driven by clean-label trends. In food applications, it prevents syneresis in yogurt (at 0.1-0.5% usage), stabilizes ice cream emulsions, and forms restructured gels in plant-based meats – reducing costs by 25-30% compared to synthetic alternatives.
For pharmaceutical buyers, CAS No 9005-38-3 excels in controlled-release tablets (viscosity grades 100-2000 cps), wound dressings (e.g., Kaltostat®), and dental impressions. Its biocompatibility (non-toxic, biodegradable) aligns with USP/NF monographs. In industrial sectors like textiles and paper, it acts as a warp sizing agent, improving fabric strength by 15%.
Key specifications for food-grade Sodium Alginate CAS No 9005-38-3 include:
- Appearance: White to off-white powder
- pH (1% solution): 6.5-7.5
- Viscosity: 400-800 cps (LV), customizable
- Moisture: ≤12%
- Microbial Limits: Total plate count <1000 CFU/g (FDA compliant)
Sourcing challenges arise from China's dominance (70% global supply, per UN Comtrade 2025), where raw material volatility from El Niño affects yields. Yet, factories like ours mitigate this with dual fermentation lines and corn-starch backups for consistent output. Regulatory compliance is paramount: our product meets FDA 21 CFR 184.1724, EU E401, and Kosher/Halal standards, with full CoA (Certificate of Analysis) per batch.
In-depth on applications: In bakery, Sodium Alginate CAS No 9005-38-3 (0.2%) enhances gluten-free dough hydration, boosting volume by 20% (Journal of Food Science, 2024). For beverages, it suspends pulp in smoothies without sedimentation. Pharma case: A USA client used our high-G alginate for probiotic encapsulation, achieving 85% survival rate through gastric acid. Industrial welding rods benefit from its binding at 2-5%.
Environmental edge: Biodegradable within 6 months in soil (vs. synthetics), aligning with 2026 USA sustainability mandates (EPA guidelines). Pricing dynamics: Bulk USA imports average $8-12/kg; our direct factory pricing starts at $4.5/kg FOB Tianjin, with volume discounts to $3.8/kg for 20MT+.
Quality control at Shijiazhuang Standard IMP&EXP: ISO 9001/HACCP certified, with in-house labs testing via ICP-MS for arsenic (<3 ppm). We offer OEM/ODM, customizing viscosity/MG ratios for your formulations. Logistics: High-speed delivery via COSCO to LA/Long Beach in 15-20 days, beating competitors' 30+.

3 Critical Pain Points When Sourcing Sodium Alginate CAS No 9005-38-3 for USA Operations
You know the drill: Supply chain disruptions hit hard.
- 1. Skyrocketing Prices: Competitors charge $10+/kg due to middlemen – eroding your ROI by 25-40%.
- 2. Inconsistent Quality: Low-grade imports fail FDA tests (e.g., high viscosity drift), causing 15% batch rejections (industry avg., Food Dive 2025).
- 3. High Shipping Costs & Delays: $2,000+ per container from distant ports, plus 4-week waits amid Red Sea issues.
- 4. Regulatory Headaches: Non-compliant alginates trigger holds at US Customs.
- 5. Limited Customization: Off-the-shelf products don't fit your formulations.
Don't let these derail your 2026 targets. See our fix →
