Yangzhou Guanmin Detergent Chemicals Co., Ltd.

Yangzhou Guanmin Detergent Chemicals Co., Ltd. is located in Yangzhou, China and lists 14 active detergent‑related products. The catalogue covers synthetic zeolite builders such as Zeolite 4A Detergent Grade (HS 3824.90) and Zeolite Detergent Grade (HS 2842.10), sodium silicate based builders including Modified Sodium Disilicate (HS 2839.19) and Complex Sodium Disilicate (HS 2835.39, 3402.90). It also offers anionic surfactants like Sodium Lauryl Ether Sulphate (SLES) (HS 3402.11) and a fluorescent whitening agent CBS‑X (HS 3204.20). Additional items include Carboxymethylcellulose Sodium (CMC) for liquid detergents (HS 3912.31) and enzyme blends for liquid detergent and dishwash applications.

The product list further contains STPP substitute options based on zeolite A, a Best STPP Substitute (HS 2835.39) and a Complex Sodium Disilicate - best STPP substitute (HS 2839.19). Two entries for Sodium Lauryl Ether Sulphate appear without HS codes, reflecting the same anionic surfactant chemistry. The catalogue also mentions phosphate‑free detergent builders and mixed enzyme systems, providing a comprehensive set of ingredients used in industrial and household detergent formulations.

The catalogue includes Zeolite 4A Detergent Grade (synthetic Na12Al12Si12O48·27H2O, HS 3824.90) which in the industry is typically supplied with particle sizes of 3 - 5 µm, moisture below 5 % and purity > 99 %. Modified Sodium Disilicate (HS 2839.19) is usually sold with a Na2O/SiO2 ratio of 1:2 and a bulk density around 1.4 t/m³. Sodium Lauryl Ether Sulphate (SLES) listed under HS 3402.11 is commonly offered as a 30 % - 40 % active liquid, with an anionic surfactant content measured by titration and a cloud point below 30 °C. CBS‑X, a stilbene‑derived fluorescent whitening agent (HS 3204.20), is normally supplied at 0.1 % - 0.5 % concentration with a spectral emission peak near 440 nm. CMC Sodium (HS 3912.31) is provided as a powder with a degree of substitution around 0.7 and a viscosity of 5000 - 15000 cP at 1 % solution.

Industry practice for detergent builders such as zeolite A (STPP substitute) and complex sodium disilicate includes bulk packaging in 20‑ft containers, 25 kg drums or 1‑ton polyethylene bags, with moisture barriers to preserve performance. Enzyme blends for liquid detergent and dishwash are usually supplied as liquid concentrates with activity expressed in protease units per gram, and require cold‑chain handling below 25 °C. Buyers often request compliance with REACH registration, a Material Safety Data Sheet (MSDS), and a Certificate of Analysis (CoA) that confirms the stated purity, particle size distribution, and pH range.
