Why Choose Non-phosphorus and Non-nitrogenous Sequestering and Dispersing Agent?
In the dyeing and finishing process, metal ions in water (such as Ca²⁺, Mg²⁺ , and Fe³⁺) may have side reactions with dyes or auxiliaries, which will cause precipitation, dyeing defects, and color spots and seriously affect the dyeing evenness and the quality of the finished product. With increasing global environmental regulations, traditional sequestering agents containing phosphorus or EDTA are facing compliance challenges.
Are you facing these issues?
- Dyeing defects and precipitation in reactive dyeing processes?
- Restrictions on the use of EDTA or DTPA, and an urgent need for environmentally friendly alternatives?
- Hard water and high heavy metal ion content, reducing dye utilization efficiency?
- Poor stability of conventional auxiliaries under high-temperature or strong-alkaline conditions? processes, ordinary auxiliaries have poor stability?
BLUELAKECHEM 11035 sequestering and dispersing powder is precisely an environmentally-friendly and efficient sequestering and dispersing solution developed to solve these problems.
What is Non-phosphorus and Non-nitrogenous Sequestering and Dispersing Powder？
- Type: Organic polycarboxylate complex
- Appearance: Colorless transparent granule, Soluble in water
- Nature: Weak anionic, Non-phosphorus, Non-nitrogenous, Biodegradable
- Application Process: Can be applied in each process of desizing, scouring, bleaching, dyeing, soaping, and finishing, etc.
- pH/ Thermal Adaptability: High stability. Suitable for high-temperature (> 130°C) and strong-alkali (pH > 12) conditions.
Performance Test
The sequestering ability of calcium ions in BLUELAKECHEM 11035 far exceeds that of conventional products.
| Chelating Ability (Ca²⁺) | 11035 | Mainstream Product | Improved Extent |
| mg CaCO₃/g | 504.4 | 284.2 | ↑ 77% |
The result shows that: Under the same using condition, 11035 can effectively capture more calcium ions, significantly improve the stability of the dyeing bath, and reduce dyeing defects or mending caused by metal ions.
Advantages of Non-phosphorus and Non-nitrogenous Sequestering and Dispersing Powder
1. Environmentally-friendly formula. Pass the international audit easily.
- Contains no phosphate, nitrogen, EDTA, or DTPA.
- Strong degradability. Meet international environmental protection standards such as EU REACH, ZDHC, OEKO-TEX, and GOTS.
2. Excellent control ability of metal ions
- High chelating value. Can effectively block Ca²⁺, Mg²⁺ , and Fe³⁺, etc.
- Reduces precipitation. Prevents the instability of the dyeing bath.
3. Has excellent dispersing performance and scale inhibition performance

- Not easy to decompose or become ineffective. Keeps the long-term effectiveness of chelating.
Application Recommendations
| Process | Proposed Dosage | Target Effect |
| Exhaust dyeing | 0.3 – 0.5 g/L | Improve the stability of dyeing bath. |
| Oxygen bleaching / Cold-pad-batch bleaching | 0.5 – 1.0 g/L | Improves whiteness. Avoids precipitation. |
| Pad dyeing / Padding | 1.0 – 2.0 g/L | Improve the stability of the dyeing bath. |
| Soaping | 0.3 – 0.5 g/L | Prevents sedimentation. Cleans more thoroughly. |
Overview of Results
- Saves dyes: Improves the utilization rate of dyes by 25%. Saves 0.51kg of dyes for each ton of fabric.
- Reduces wastewater emission: Non-phosphorus and environmentally-friendly formula.
- Decreases energy consumption: Extends cleaning period. Saves steam and labor costs.
- Reduces mending: Improves evenness of dyeing. Decreases the mending rate by more than 30%.
