Oxidized starch

Oxidized Starch used in paper industries. It is manufactured from highly refined starch with controlled conditions of SOP

Oxidation is the only type of modification where two different forms of modification take place simultaneously a degrading and stabilization like the acetylation

Native starches are treated with a variety of oxidizing agents.
Oxidized starches have shorter chain lengths than native starches.
It improves whiteness and reduces microbiological content. In addition, the hydrogen bonding reduces the tendency to retro gradation.
It producing soft-bodied gels of high clarity,
Oxidized starches are the best thickener for applications requiring gels of low rigidity.
It improves adhesion.
Oxidized starch is widely used in surface sizing for paper industry and for warp sizing in textile industry.
It is used as a wet end additive for surface treatment of the paper & board
It improves the surface strength and provides hold out of printing inks

The oxidized starches - in high concentrations - are characterized by giving a very low viscosity during boiling and a very high viscosity during cooling due to the high content of dry matter
It Improved printability and pigment coating
