Innovation of Alkyl Polyglucosides in Laundry Detergents
Laundry detergents in the market are primarily divided into two categories: liquid and powder, with one of the most crucial performance indicators being stain removal capability. Generally, cationic surfactants exhibit relatively poor performance in this aspect. However, among them, components like C12-14 CAPG, representing cationic alkyl polyglucosides, possess exceptional stain removal capabilities. Not only do they exhibit powerful stain removal on their own, but they also significantly enhance the stain removal efficiency of anionic surfactants in the original system when added.
Cationic alkyl polyglucoside exhibits excellent performance stability, and their addition to laundry liquids and powders does not alter their original properties. They adapt well to various processing requirements and demonstrate substantial compatibility with different systems. Furthermore, the incorporation of cationic alkyl polyglucosides enhances the fineness of foam in laundry detergents, simultaneously reducing friction and imparting a softening effect to fabrics. This is particularly advantageous for the delicate washing of garments with high detailing requirements.
The application of cationic alkyl polyglucosides in laundry detergents demonstrates strong adaptability. Not only does it perform well in cold-water washing, but its addition also reduces the irritability of the system, making it more suitable for hand washing. Furthermore, its inclusion enhances anti-static properties, softness, and reduces shrinkage, providing better results in the washing of fabrics such as silk and wool.

Innovation of Alkyl Polyglucosides in Dishwashing Detergents
Dishwashing detergents are widely used in people's daily lives, and whether for handwashing or machine washing, they are required to meet criteria such as low toxicity, strong degreasing ability, easy rinsing, and no residue. In recent years, there has been a continuous pursuit of "two-in-one" dishwashing detergents that combine cleaning and disinfecting properties. The introduction of cationic alkyl polyglucoside quaternary ammonium salts has achieved this goal, providing powerful support for the innovation of dishwashing detergents.
In dishwashing detergents, the addition of cationic alkyl polyglucosides not only does not alter the performance of anionic surfactants but also results in significant improvements in stain removal capability and foaming properties. The mixed system exhibits excellent performance, and the process is simple, providing an efficient and feasible approach for enhancing dishwashing detergents.
The comprehensive properties of cationic alkyl polyglucoside quaternary ammonium salts, including low toxicity, potent antibacterial effects, and enhancement of the performance of anionic surfactants, make them easily compatible with anionic surfactants without causing precipitation. Its overall performance in dishwashing detergents improves aspects such as stain removal, foam, and residue-free cleaning, making it a significant innovative highlight in dishwashing detergents.
