HPMC (Hydroxypropyl Methylcellulose) is widely used in detergents. Its main uses include thickening, improving foam stability, and serving as a suspending agent and gelling agent.
1. Thickener
HPMC is a high molecular weight cellulose derivative with excellent thickening properties. Adding HPMC to detergents can significantly increase the viscosity of detergents, making the detergents have better fluidity and coating properties. This is crucial for many types of detergents (e.g. liquid laundry detergent, dish soap, etc.) as proper viscosity can improve the experience of using the product.
2. Improve foam stability
Another important role of HPMC in detergents is to improve foam stability. Foam is an important indicator of detergent cleaning performance. HPMC can form stable foam and increase the durability of the foam, thereby improving the cleaning effect of the detergent. Its foam stability is especially obvious during use, making the detergent’s foam last longer during use and improving user experience.
3. Suspending agent
HPMC has excellent suspension properties and can effectively prevent solid particles in detergents from settling. It is often necessary to add some granular ingredients to detergents, such as detergents or detergents. HPMC can help these particles to be evenly distributed in the liquid and avoid sedimentation or stratification. This ensures consistency and effectiveness of the detergent during use.
4. Gelling agent
HPMC can also be used as a gelling agent to provide certain gelling properties for detergents. By adjusting the concentration of HPMC, the fluidity and consistency of the detergent can be controlled. This is particularly important for detergent products that require a specific viscosity. For example, some detergents need to have gel-like properties to make them easier to apply or to focus on cleaning certain areas.
5. Improve stability
HPMC has good chemical and thermal stability and can maintain its physical and chemical properties under various pH and temperature conditions. This allows HPMC to function stably under different formulations and storage conditions, improving the overall stability of the detergent.
6. Other functions
Lubricity: HPMC can give the detergent a certain degree of lubricity, reducing the wear on surface materials during the washing process, especially when cleaning delicate items.
Non-toxic and biodegradable: As a natural cellulose derivative, HPMC has good biodegradability and non-toxicity, ensuring the safety of the environment and users.
The application of HPMC in detergents mainly focuses on thickening, improving foam stability, suspension, gelling, etc., which significantly improves the performance and usage experience of detergents. Its good chemical stability and biodegradability also make HPMC a very popular additive and plays an important role in the detergent industry.
