■ The above data are obtained from specimens in the solution by soaking the product into solvent, the results of references can only be taken as reference for actual use. In addition, with the brackets, according to its structure and material manufacturers data obtained inference results. Since the majority of users have different working environment, therefore, please contact us for consultation before  actual use of our products. In general, the hydrocarbon-based drugs have the carbon content of different sizes, the smaller the carbon content, the expansion of the stronger the effect.
