Dispersant polymers are used in institutional cleaners, such as industrial and commercial cleaning agents, to improve the cleaning performance and prevent soil re-deposition. They are also known as anti-redeposition agents or anti-soil redeposition agents.

The functions of dispersant polymers for institutional cleaners include:

1. Soil suspension: Dispersant polymers help to suspend soils and prevent them from settling back onto the surface being cleaned. They do this by forming a protective layer around the soil particles, which keeps them in suspension.
2. Stain prevention: Dispersant polymers help to prevent stains from forming by keeping the soil particles suspended in the cleaning solution. This prevents them from settling onto the surface and forming stains.
3. Scale prevention: Dispersant polymers can also prevent scale formation by sequestering metal ions that can cause scaling.
4. Improved cleaning efficiency: Dispersant polymers can improve the efficiency of cleaning agents by helping to disperse soils and improve the cleaning solution’s wetting ability. This can help to reduce cleaning time and effort.
5. Compatibility with other cleaning agents: Dispersant polymers are typically compatible with a wide range of other cleaning agents, making them a versatile and effective additive for institutional cleaners.
