How can cellulose ether improve its decontamination ability and foam stability in detergent?
Cellulose ether(such as sodium carboxymethyl cellulose (CMC), hydroxyethyl cellulose (HEC), etc.) as functional additives in detergent can improve the decontamination ability and foam stability by adjusting the rheological properties of the system, enhancing the interface effect and cooperating with other components. The specific functions and mechanisms are as follows:
1、 Improvement effect and mechanism of decontamination ability
2、 Improvement of foam stability and its mechanism
3、 Precautions in practical applications
Usage control The amount of cellulose ether added should be moderate (usually 0.1%~0.8%): Low dosage: Insufficient thickening and foam stabilization effects; Too high dosage: the solution viscosity is too high, and the foam is too viscous, which will affect the washability (foam is not easy to clean), and may increase production costs. Type Selection Carboxymethyl cellulose sodium (CMC): cost-effective, with thickening, dispersion, and certain chelating ability, suitable for mid to low end dishwashing detergents; Hydroxyethyl cellulose (HEC): It has better salt and temperature resistance, excellent compatibility with surfactants, longer foam stability, and is suitable for hard water resistant formulations. Compatibility with other components Dishwashing detergent often contains enzyme preparations (such as protease, lipase), preservatives, etc. Please pay attention to: Cellulose ethers (especially CMC) may precipitate with high valence metal ions (such as Fe ³ ⁺), and the pH of the system needs to be controlled (usually neutral to weakly alkaline); Avoid mixing with strong oxidants to prevent the breakage of cellulose ether molecular chains and loss of function. summary Cellulose ether in detergent can enhance decontamination ability through thickening and retention, dispersion and suspension, and cooperating with surfactant. At the same time, it can improve the stability of foam by strengthening the strength of foam film, delaying drainage, and controlling bubbles. Its essence is to optimize the rheological properties and interface behavior of detergent by using the hydrophilicity of molecular chain, long chain structure and synergistic effect with other ingredients, which not only improves the actual decontamination efficiency, but also meets the consumer's demand for "rich and lasting foam" experience. In formula design, it is necessary to select the appropriate type and dosage of cellulose ether based on cost, water quality, and performance requirements to achieve optimal results.
