Alginate de sodium 300-800CPS-Haute pureté pour les applications alimentaires et cosmétiques
Sodium Alginate 300-800 CPS is a refined, high-purity polysaccharide extracted from sustainably harvested brown seaweed (Phaeophyceae). With a controlled viscosity range of 300–800 centipoise (1% aqueous solution, 20°C), this versatile hydrocolloid serves as a critical texturizing agent in food innovation and cosmetic science. Its unique ability to form heat-stable gels, create protective films, and modify rheology makes it indispensable for clean-label, plant-based, and high-performance applications.
Core Functional Properties
1. Precision Viscosity Control
- Delivers 300–800 cP viscosity at 1% concentration (Brookfield LVF, spindle 3, 60 rpm)
- Exhibits pseudoplastic behavior with shear-thinning recovery >90% (ISO 2555)
- Maintains viscosity stability across pH 5–11 (FDA 21 CFR 184.1724 compliant)
2. Ion-Responsive Gelation
- Forms instant thermo-irreversible gels with calcium ions (0.2–2.0% Ca²⁺)
- Gel strength range: 100–500 g/cm² (Bloom method, calcium-dependent)

Formulation Guidance
Standard Gel Preparation
- Hydrate 1–2% alginate in deionized water (40–50°C, 30 min)
- Add 0.1–0.5% calcium salt (lactate/gluconate for slow gelation)
- Adjust pH to 6–7 for optimal crosslinking
Synergistic Systems
- Plant-based cheese: 1.2% alginate + 0.3% κ-carrageenan
- Hydrating serum: 0.8% alginate + 1% hyaluronic acid
- Low-oil dressing: 0.4% alginate + 0.2% xanthan gum
Sodium Alginate 300-800 CPS bridges natural sourcing with cutting-edge functionality, empowering formulators to achieve texture innovation while meeting clean-label and sustainability targets. Its unique ionic reactivity and thermal stability enable breakthroughs in alternative protein development, reduced-additive cosmetics, and circular economy packaging solutions.
