Its dyeing auxiliaries are known for high performance and eco-friendliness, offering innovative solutions to the industry and exporting products to over 10 countries and regions worldwide.

‌Benzoic Acid and Its Derivatives: Enabling Dyeing with Diverse Applications‌

‌Benzoic acid (CAS No. 65-85-0)‌ serves as a preservative and pH regulator, and also supports dye synthesis and functional finishing, enhancing the color brightness and durability of textiles.

‌Benzyl benzoate (CAS No. 120-51-4)‌, a star product, is an eco-friendly dyeing carrier. It weakens intermolecular forces in polyester fibers, enabling dyeing at 98–100°C under normal pressure—reducing energy consumption and preventing fiber damage. It also offers excellent leveling and migration properties, helping correct minor dyeing inconsistencies and reducing waste. Non-toxic, odorless, and biodegradable, it rinses easily after dyeing, aligning with green dyeing principles.

‌Diethylene glycol dibenzoate‌ and ‌dipropylene glycol dibenzoate‌ can be blended with benzyl benzoate, doubling as eco-friendly plasticizers. They improve fabric softness and dyeing uniformity and are highly compatible with disperse dyes—requiring no modifications to existing equipment or processes.

‌Multifunctional Auxiliaries: Expanding Dyeing Possibilities‌

‌Benzophenone (CAS No. 119-61-9)‌ is a key intermediate in dye synthesis and acts as a UV blocker to enhance textile lightfastness. It aids functional finishing processes and can even impart a special fragrance to fabrics.

‌Benzyl chloride (CAS No. 100-44-7)‌ is a crucial intermediate in the synthesis of acid, direct, and reactive dyes, ensuring rich color variety and stability across various textiles.

‌Pentaerythritol (CAS No. 115-77-5)‌ functions as a crosslinking agent, emulsifier, and more, improving fabric wrinkle resistance, abrasion resistance, and dyeing uniformity.

‌Eco-carrier 95‌ integrates carrier, leveling, and correction functions. It disperses dyes, improves dyeing uniformity, and reduces pollution, supporting green manufacturing.
