Sodium silicate is added to detergents to control viscosity and achieve the desired density in powder detergents. It helps bind particles together, providing appropriate hardness while not affecting water solubility. Sodium silicate enhances several properties of detergents, including:
1.Moisture Control: It reduces the surface tension of liquids.
2.Wetting Ability: It ensures proper wetting of the hard surfaces of plant fibers during washing.

Emulsification: Sodium silicate disperses grease into fine droplets in the cleaning solution, allowing the grease to be removed along with the rinse water.

Deflocculating: Sodium silicate breaks down inorganic stains or particles into smaller particles in the cleaning solution.
3.Anti-redeposition: Dirt suspended in water will not redeposit onto clean areas.
4.Power buffer: Due to its alkaline nature, silicate helps control the pH of acidic detergent solutions and reduces pH fluctuations.
5.Corrosion protection: Silicate helps protect metal surfaces susceptible to corrosion from other ingredients in detergents.
6.Separation power and conditioner: Silicate removes minerals, thereby reducing the hardness of rinse water through ion exchange mechanisms that form compounds.
