Jinan Tonex Chemical Co.,Ltd

Based in China, Jinan Tonex Chemical Co.,Ltd lists six active products in its catalogue. The company’s offerings fall under the broader categories of Optical Brightening Agents and Optical Brighteners, which are part of the chemicals and allied products sector. Each product is identified by a distinct trade name such as FP-127, OB-1, CBS‑X, SWN, Er‑i L (Ps‑1) and BA. The catalogue does not provide HS codes, so buyers must reference the general HS chapter for organic chemicals when arranging customs documentation. The supplier is classified in the harbor trust tier, indicating a baseline level of verification in trade platforms.

The six listed items are all variants of optical brightening agents used to enhance the whiteness of textiles, paper, and detergents. Product names suggest different chemical families, for example the “FP‑127” line and “CBS‑X” series, which are typical nomenclature for stilbene‑based brighteners. Buyers can expect these chemicals to be supplied as powders or liquid concentrates, common formats for this category. The catalogue’s focus on optical brighteners excludes other chemical families, keeping the product portfolio narrowly targeted. Potential importers should note that the supplier’s location in China aligns with the country’s large‑scale production of textile‑grade optical brighteners.

Jinan Tonex Chemical Co.,Ltd’s catalogue comprises six optical brightening agents: FP‑127, OB‑1, CBS‑X, SWN, Er‑i L (Ps‑1) and BA. These products are typical of the stilbene‑type or coumarin‑type brighteners that deliver fluorescence under UV light, raising the perceived brightness of fabrics and paper. In the industry, optical brighteners are graded by fluorescence intensity, purity (often >99 %), and solubility in water or organic solvents. Common specifications include a maximum moisture content of 1 %, particle size below 100 µm for powder forms, and a UV‑absorption peak around 340‑380 nm.

Buyers of optical brighteners usually require compliance with REACH registration in the European Union and SDS (Safety Data Sheet) documentation. ISO 9001 quality management certification is a frequent prerequisite for large‑scale detergent manufacturers. The products may be offered in 25 kg drums, 500 kg bulk bags, or 20 ft containers, matching standard logistics for bulk chemicals. Typical grades are designated by trade names rather than numeric codes, but the industry distinguishes between high‑purity grades for textile finishing and lower‑purity grades for household detergent formulations.
