Liquid octylisothiazolinone 98 oit biocide CAS 26530-20-1 

Chemical Name: 2-n-octyl-4-isothiazolin-3-one(OIT 98)


CAS No: 26530-20-1


OIT 98% biocide is a broad-spectrum fungicida that has been recommended and widely used for tankside control of fungi in metalworking central systems. The broad-spectrum biocide is also an effective fungicide for use in many metalworking fluid concentrates with the appropriate stabilizer package. Due to the wide variations in metalworking fluid formulations, laboratory or small-scale tests are recommended to evaluate this biocide in use- dilution and concentrate metalworking fluids before they are commercialized. The broad-spectrum biocide is a highly effective, industrial fungicide that exhibits excellent fungistatic and fungicidal activity against fungi, including yeasts and mold, and Gram-Positive bacteria, and limited activity against Gram-Negative bacteria. Commonly known as octhilinone, 2-N-octil-4-isotiazolin-3-one is the active ingredient of Octilisotiazolinona 98% biocide It is supplied as a 98 percent active liquid in propylene glycol.
Typical Properties
These properties are typical but do not constitute specifications
Appearance: Pale yellow to amber liquid
Active Ingredient: 98% 2-n-octyl-4-isothiazolin-3-one
Water: 1.0% max
PH(1% solution):4.0-7.0
Specific Gravity (g/ml) at 20°C:1.03-1.05
It is soluble in methanol, ethanol, propylene glycol, acetone, ethyl ether, et-hyl acetate, chloroform, butyl Cellosolve, corn oil, and mineral oil. The solubility in toluene is 25% w/v. The solubility in water at 25°C is 480 ppm (active ingredient), although this may be increased by using suitable surfactants and emulsifiers. OIT fungicida is insoluble in heptane.
In concentrate and use-dilution metalworking fluids, the compatibility is concentration-dependent and varies from formulation to formulation. It is compatible with most metalworking fluid additives, including surfactants and amines.
Compatibility with amines may vary by the type, concentration and pH. Strong reducing agents, such as sulfides, mercaptans, bisulfites and metabisulfites, or strong oxidizingagents, such as hypochlorites, may affect the efficacy of OIT biocide.  Laboratory or small-scale tests are recommended in order to evaluate it compatibility in use-dilution or concentrate metalworking fluids prior to commercialization.
In-Use Stability: It has excellent stability in end use dilutions of metalworking fluids. It is stable over a wide pH range (4-10) in water and in metalworking fluid systems. Concentrate Stability OIT Biocide stability, in metalworking fluid concentrates, is variable. We recommend checking stability and performance before commercialization of products.
Storage Stability
In general, the storage stability is excellent. The shelf life of the product is nominally twelve years at 25°C. It is strongly recommended, however, that both the stability and compatibility of OIT 98% fungicida in metalworking fluid formulations or systems be thoroughly examined before commercialization.
Key Features & Benefits

microorganisms, eliminates clogged lines and filters and musty odors caused by fungi
Highly soluble in water and does not foam
Easy to dose
Provides long lasting fungal control
Cost effective versus competitive tankside treatments
Fast acting
Quickly controls growth and activity of odor-causing fungi

Effective at low use rates and Biodegradable

Better for the environment
Does not contain, release or generate
Not subject to concern about formaldehyde, a known Formaldehyde carcinogen

Applications/ Directions for Use
Method of Addition
It should be directly dispensed into metalworking fluid concentrates or use-dilution metalworking fluids using a metering pump or other point-of-use device where possible and uniformLy dispersed throughout the fluid.
Fluid Concentrate
It should be added to metalworking fluid concentrates at a level that ensures the final use-dilution fluid will contain 55 to 167 ppm of product (25 to 75 ppm active ingredient). The stability in a given concentrate should be determined prior to commercialization.
Package:25Kg per drum, 200Kg per drum or 1000Kg per IBC drum.
