Fabric cleaning raw materials cover more than one product category. From dry cleaning solvents such as Tetrachloroethylene to nonionic surfactants, SLES and betaine types, the right choice depends on the application system. Dotachem supplies a range of cleaning and textile care chemicals from China, with product information, samples and export documentation available.

Learn why NP-9 Nonylphenol Ethoxylate is commonly used in industrial cleaning, textile processing and emulsification systems, and how Dotachem supports NPE grade selection.

Explore how Dimethylformamide (DMF) supports pharmaceutical intermediate synthesis, why solvent consistency matters, and how Dotachem provides sourcing support from China.

Tween 20 and Tween 80 are two commonly used Polysorbate surfactants. This article compares their HLB value, emulsification performance and application focus to help buyers choose the right grade.

Selecting the ideal Nonylphenol Ethoxylate grade requires balancing solubility, application temperature, and formulation type. For aqueous systems, NP-9 or NP-10 may offer the best compromise between solubility and emulsification. For oil-rich systems, lower EO grades such as NP-2 or NP-4 may perform better due to their higher cloud points and lower HLB.
