HPMC is commonly used in laundry detergents as a thickener, stabilizer, and emulsifier. It helps to improve the texture and viscosity of the detergent, making it easier to apply and ensuring that it stays mixed together properly.
 

In laundry detergents, HPMC can help to prevent the separation of the different components of the detergent, such as the surfactants and the builders, which can occur when the product is stored for long periods of time. It can also improve the suspension of the cleaning agents in the water, ensuring that they are evenly distributed throughout the wash.

HPMC can also improve the overall performance of laundry detergents by providing benefits such as:

1. Enhanced cleaning power: HPMC can help to improve the ability of the cleaning agents in the detergent to dissolve and remove dirt and stains from fabrics.

2. Better stain removal: HPMC can help to improve the ability of the detergent to remove stubborn stains, such as oil, grease, and grass stains.

3. Improved rinsing: HPMC can help to ensure that the detergent is thoroughly rinsed from fabrics, leaving them clean and fresh-smelling.

When selecting an HPMC powder for use in laundry detergents, it is important to choose a product that is compatible with the other ingredients in the formulation and that meets the desired specifications for viscosity, texture, and stability. It is also important to consider factors such as the purity and consistency of the product, as well as the reliability of the manufacturer.
