1️⃣ Introduction to Sodium Alginate

Sodium Alginate (Algin) is a natural hydrocolloid extracted from brown seaweed. It is widely used in food, pharmaceuticals, cosmetics, textiles, and industrial applications due to its thickening, gelling, stabilizing, and emulsifying properties.

At Chibio Biotech, we provide a wide range of sodium alginate products with different viscosity levels and gel strengths to meet diverse industry needs.
