Function of HD-100 in Liquid Laundry Detergents
Recommended dosage: 0.18% – 0.3%
HD-100 is a high-performance anti-redeposition and soil-release polymer designed specifically for modern liquid laundry formulations. When added at 1.8–3‰, it significantly enhances overall washing performance and fabric care.
HD-100 works through multiple synergistic mechanisms:
1. Prevents soil from reattaching to fabrics
During the washing process, dirt and colored particles are lifted from textiles but tend to float in the wash liquor. Without protection, these soils can easily redeposit, especially on light-colored garments. HD-100 forms a protective hydrophilic film on fiber surfaces, ensuring suspended soils remain dispersed and are rinsed away efficiently.
2. Improves whiteness retention and brightness
By blocking secondary staining, HD-100 helps detergents maintain long-term whiteness and prevent greyish or yellowish buildup. Even after repeated washes, fabrics stay cleaner and brighter.
3. Enhances washing performance in low-temperature and short-cycle washes
Modern consumers increasingly use cold-water and fast-wash modes. HD-100 compensates for the reduced washing strength in these conditions by stabilizing soils and improving detergent effectiveness.
4. Provides fabric-care benefits
The polymer layer deposited by HD-100 reduces fiber surface friction, helping to protect fabric structure, minimize pilling, and extend garment life. This makes it suitable for delicate textiles and premium laundry products.
5. Excellent compatibility
HD-100 shows strong compatibility with surfactants, enzymes, optical brighteners, and fragrance systems. It remains stable in a wide pH range and resists hydrolysis, making it ideal for both concentrated and standard-grade liquid detergents.

Additional Advantages of HD-100 in Liquid Laundry Applications
Beyond its core anti-redeposition performance, HD-100 also delivers several extended functional benefits to modern laundry detergent systems:
6. Boosts particulate soil removal
HD-100 improves the detachment of fine particulate soils such as dust, carbon black, and clay. These particles are usually difficult to remove because of their small size and strong adherence to fibers. HD-100 helps break soil–fiber interactions and keeps the particles suspended throughout the wash cycle.
7. Stabilizes detergent formulations
HD-100 enhances system stability by improving the dispersion of insoluble components, reducing phase separation, and preventing viscosity drift during long-term storage. This gives manufacturers greater flexibility in designing both high-active and cost-optimized formulations.
8. Supports enhanced enzyme efficiency
By modifying the fabric surface and preventing soil re-deposition, HD-100 helps enzymes (such as protease, amylase, cellulase) maintain direct contact with stains. This synergistic effect improves stain removal performance and allows formulators to lower enzyme dosage while maintaining washing quality.
9. Reduces fabric greying over repeated cycles
One of the biggest complaints in laundry care is that clothes, particularly cotton, gradually turn dull or grey. HD-100 minimizes cumulative soil build-up, ensuring that fabrics retain their original color tone and brightness even after dozens of washes.
10. Suitable for eco-friendly and phosphate-free detergents
As global regulations push for more sustainable formulations, HD-100 serves as an effective performance booster in phosphate-free, low-builder, and low-alkalinity systems. It compensates for the loss of traditional builders, allowing eco-detergents to achieve high cleaning performance.
11. Excellent performance even at low dosage
At just 0.18–0.3%, HD-100 delivers impressive cleaning enhancement without significantly increasing formulation cost. Its high efficiency makes it ideal for mass-market detergent brands as well as premium concentrates.
12. Enhances user experience
Clothes washed with HD-100 not only look cleaner but also feel softer and smoother due to its mild fabric-conditioning effect. Consumers notice a tangible difference—cleaner whites, brighter colors, and a fresher washing appearance.
