CMIT/MIT is a liquid biocide with outstanding advantages such as rapid inhabitation of growth and macromolecule synthesis, broad spectrum activity, effective at low concentration and against biofilm as well as a wide pH range, biodegradable non-persistent in the environment, non-surface activity, infrequent dosing, easily deactivated, compatibility, low toxicity, water soluble, non-foaming, cost effectiveness etc. The active ingredient is a mixture of two isothiazolines. CMIT/MIT is ideally suited to meet the requirement of an industrial water treatment biocide for bacteria, fungi and algae paper mill slimicide.
Methyl tert-butyl ether (MTBE) is a colorless, transparent, low-viscosity, volatile liquid with a distinctive odor and an oxygen content of 18.2%. lts vapor is heavier than air. Diffuses along the ground and burns when co-existing with strong oxidants. The main use of methyl tert-butyl ether is as an organic solvent and can also be used as a gasoline additive to make it more antiknock. Application ethyl tert-butyl ether (MTBE) is mainly used as gasoline additive, has excellent knock resistance, improves octane number, and can also be cracked to produce isobutene has good miscibility with gasoline, less water absorption, no pollution to the environment, can be improved as an analytical solvent, extractant, in chromatography especially high pressure liquid chromatography as a removal agent, and some polar solvents such as water, methanol, ethanol and other azeotrope formation. Mtbe also has a mild narcotic effect.

Sugar Esters E473, CAS No.37318-31-3 , commonly known as Sucrose esters of fatty acids, manufacturing process by esterifying sucrose with fatty acids. By varying the degree of esterification of the sucrose molecule it is possible to obtain emulsifiers with HLB values ranging from 1 up to 16. It is a light yellow powder, a non-ionic surfactant and is used as an emulsifier in dairy products, baked goods, soft drinks, jelly, cake and candy. Sucrose Fatty Acid Esters are a mixture of mono-, di-, and tri-esters of sucrose with fatty acids derived from edible vegetable or hydrogenated vegetable oils and fats.
