Sodium Carboxymethyl Cellulose Chemical Formula: In-Depth Technical Guide

The sodium carboxymethyl cellulose chemical formula is a cornerstone for industrial buyers sourcing this versatile additive. Known as CMC or cellulose gum (E466 in food applications), its precise structure is [C₆H₇O₂(OH)₂OCH₂COONa]_n, where n represents the degree of polymerization, typically ranging from 200 to 2000 for commercial grades.

This anionic polysaccharide derivative starts with native cellulose, a β-1,4-linked D-glucose polymer. Through carboxymethylation, hydroxyl groups (-OH) on the glucose units react with sodium monochloroacetate (ClCH₂COONa) under alkaline conditions, substituting -OCH₂COONa groups. The degree of substitution (DS) averages 0.7-1.2, directly impacting viscosity and solubility—critical for your formulations.

Visually, the sodium carboxymethyl cellulose chemical structure features a linear cellulose backbone with pendant carboxymethyl groups providing negative charges for water-binding and thickening. FTIR spectroscopy confirms peaks at 1600 cm^-1 (COO^- asymmetric stretch) and 1420 cm^-1 (symmetric stretch), verifying purity above 99.5% in our products.

Why does the formula matter for you? In food additives, it ensures suspension stability in sauces; in pharma, controlled release in tablets. US FDA GRAS status (21 CFR 182.1745) mandates exact specs—our CMC matches with viscosity 800-1200 cps (2% solution), pH 6.5-8.0.

Breaking down the formula: Each anhydroglucose unit (AGU) formula weight ~323 g/mol (DS=1). Polymerization yields molecular weights of 90,000-600,000 Da. Solubility stems from hydrophilic -COONa groups, swelling in water to form reversible gels. Compared to HPMC, CMC's lower gel strength suits high-shear processing.

Manufacturing aligns with the formula via alkalization (NaOH), etherification, purification, and drying. Our two fermentation departments use corn starch-derived cellulose, ensuring batch consistency. Export data: 500+ tons/month to USA, Brazil, Australia—zero recalls since 2004.

Long-tail searches like sodium carboxymethyl cellulose chemical structure reveal its repeating unit: C₆H₉O₄(OCH₂COONa). NMR (¹H/¹³C) shows shifts at 4.3 ppm (-CH₂COO) and 100-105 ppm (anomeric C1). Purity tests (HPLC) detect <0.1% insoluble matter.

For feed additives, the formula enables ice-cream texturing (up to 0.5% usage) per EU Reg 1333/2008. Pharma grades (USP/NF) require heavy metals <10 ppm—our QA exceeds this. LSI terms: carboxymethylcellulose sodium formula, CMC Na structure, E466 molecular weight.

Historical context: Developed in 1918 by Lezer, commercialized post-WWII. Today's grades: high-viscosity (HV-CMC) for drilling muds, low-viscosity (LV-CMC) for beverages. Our USP: OEM customization of DS for your exact sodium carboxymethyl cellulose chemical formula needs.

Analytical validation: Gel permeation chromatography (GPC) confirms Mw/Mn polydispersity <2.0. Thermal stability to 250°C (TGA). In solutions, zeta potential -20 to -40 mV ensures stability. For US importers, harmonized tariff 3912.31.00 applies—our docs streamline customs.

Applications decode the formula's power: 0.2-0.5% in gluten-free doughs mimics elasticity; 1-3% in toothpaste binds abrasives. Safety: LD50 >5000 mg/kg (rat). Ready to spec your formula?

Your CMC Procurement Challenges in 2026

As a purchasing manager, you face skyrocketing prices—up 28% YoY per ICIS reports—due to supply chain disruptions from China competitors prioritizing domestic needs.

• High Prices: Middlemen inflate costs by 40%, eroding your ROI on food/pharma lines.
• Low Quality: Inconsistent DS leads to 15% batch failures, per USDA audits.
• High Shipping Costs: Delays average 45 days, with surcharges hitting $2/kg to USA ports.
• Unreliable Service: Poor OEM support wastes 20 hours/week on re-quotes.
• Quality Variability: Subpar formula purity causes viscosity drops in humid storage.
• Regulatory Risks: Non-FDA compliant CMC risks recalls, costing $100K+.

Scenario: Your ice-cream line gels prematurely—lost $50K production. See our fix.
