What is the use of HPMC in dishwashing liquid?

Hydroxypropyl methylcellulose (HPMC) is a synthetic polymer derived from cellulose, a naturally occurring polysaccharide found in plants. It is a white, odorless, tasteless powder that is soluble in cold water and forms a gel when heated. HPMC is used in a variety of industries, including pharmaceuticals, cosmetics, food, and detergents. In the detergent industry, HPMC is used as a thickening agent in dishwashing liquids.

The use of HPMC in dishwashing liquids provides several benefits. First, it helps to thicken the liquid, giving it a more viscous and creamy texture. This makes it easier to spread and lather, ensuring that the detergent is evenly distributed on the dishes. Additionally, the thickening agent helps to suspend dirt and grease particles in the liquid, allowing them to be more easily removed from the dishes.

HPMC also helps to stabilize the dishwashing liquid, preventing it from separating into layers. This ensures that the detergent is effective and consistent throughout its shelf life. Additionally, HPMC helps to reduce the amount of foam produced by the detergent, making it easier to rinse off the dishes.

Finally, HPMC helps to improve the cleaning performance of the dishwashing liquid. The thickening agent helps to increase the surface tension of the liquid, allowing it to adhere better to the dishes and penetrate into the dirt and grease particles. This helps to lift and remove the particles more effectively, resulting in cleaner dishes.

In summary, HPMC is a synthetic polymer derived from cellulose that is used as a thickening agent in dishwashing liquids. It helps to thicken the liquid, suspend dirt and grease particles, stabilize the detergent, reduce foam, and improve cleaning performance. All of these benefits make HPMC an essential ingredient in dishwashing liquids.
