Oxidized starch

Oxidized starch (CAS 65996-62-5) is a chemically modified starch produced by treating native starch with oxidizing agents to introduce carbonyl and carboxyl groups into the polymer chain.

Where is Oxidized starch used?

• Paper: binder and coating agent applied at the size press or in surface coating formulations to improve smoothness, ink holdout and surface strength
• Textile: warp sizing agent for yarn coating
• Food: thickener and stabilizer in sauces, puddings and processed foods
• Construction: binder in adhesives and gypsum board formulations to control rheology and improve adhesion to mineral substrates
• The modification reduces viscosity, improves film-forming capacity and increases paste clarity compared to native starch.

Good to know: Degree of oxidation and viscosity grade vary by application; suppliers typically offer multiple viscosity profiles to match specific process requirements.

Commercial specifications

• Derived from corn, potato, tapioca or wheat starch bases
