Carboxymethyl cellulose (CMC) is a common water-soluble polymer compound, widely used in washing powder formula as a stabilizer.
1. Thickening effect
CMC has good thickening properties and can effectively increase the viscosity of washing powder solution. This thickening effect ensures that the washing powder will not be too diluted during use, thereby improving its use effect. High-viscosity laundry detergent can form a protective film on the surface of clothing, allowing the active ingredients to play a better role and enhance the decontamination effect.
2. Suspension stabilizer
In the washing powder formula, many active ingredients and additives need to be evenly dispersed in the solution. CMC, as an excellent suspension stabilizer, can prevent solid particles from precipitating in the washing powder solution, ensure that the ingredients are evenly distributed, and thus improve the washing effect. Especially for washing powder containing insoluble or slightly soluble components, the suspension ability of CMC is particularly important.
3. Enhanced decontamination effect
CMC has a strong adsorption capacity and can be adsorbed on stain particles and clothing fibers to form a stable interface film. This interfacial film can prevent stains from being deposited on clothes again, and play a role in inhibiting secondary pollution. In addition, CMC can increase the solubility of detergent in water, making it more evenly distributed in the washing solution, thereby improving the overall decontamination effect.
4. Improve the laundry experience
CMC has good solubility in water and can quickly dissolve and form a transparent colloidal solution, so that the washing powder will not produce floccules or insoluble residues during use. This not only improves the use effect of the washing powder, but also improves the user’s laundry experience, avoiding secondary pollution and clothing damage caused by residues.
5. Environmentally friendly
CMC is a natural polymer compound with good biodegradability and low toxicity. Compared with some traditional chemical synthetic thickeners and stabilizers, CMC is more environmentally friendly. Using CMC in the washing powder formula can reduce pollution to the environment and meet the requirements of modern society for environmental protection.
6. Improve the stability of the formula
The addition of CMC can effectively improve the stability of the washing powder formula and extend its shelf life. During long-term storage, some active ingredients in washing powder may decompose or become ineffective. CMC can slow down these adverse changes and maintain the effectiveness of washing powder through its good protection and stabilization.
7. Adapt to various water qualities
CMC has strong adaptability to water quality and can play a good role in both hard water and soft water. In hard water, CMC can combine with calcium and magnesium ions in water to prevent the influence of these ions on the washing effect, ensuring that washing powder can maintain high decontamination ability under different water quality environments.
As an important stabilizer in the formula of washing powder, carboxymethyl cellulose has multiple advantages: it can not only thicken and stabilize the washing powder solution, prevent the precipitation of solid particles, and improve the decontamination effect, but also improve the user’s laundry experience, meet environmental protection requirements, and enhance the overall stability of the formula. Therefore, the application of CMC is indispensable in the research and development and production of washing powder. By using CMC reasonably, the quality and performance of washing powder can be significantly improved to meet the needs of consumers.
