Silicates in solution offer numerous advantages in detergent formulations:
- Protection against corrosion of the metal parts of washing machines.
- High buffering capacity in the pH range of 9 – 12.
- Alkalinity that neutralizes acids.
- Efficient emulsification and saponification of oils and fatty acids.
- Deflocculation and suspension of particulates.
- Compensation of water hardness
Furthermore, silicates do not harm the environment and are compatible with many other raw materials used in detergents. Potassium silicates are sometimes preferred in formulations aimed at preventing solubility issues. In industrial detergent formulations, the presence of silicates is higher.
These products are intended for demanding applications that involve contact with fats and oils (metal cleaning, dairy cleaning, meat industry cleaning, etc.) or for specific surfaces (floor cleaners).
Prochin silicates guarantee two vital characteristics in these applications: excellent saponification and a deflocculating effect.
