Isocil is a manufacturing use product which can be used to make high performance biocides. It has extremely broad spectrum activity, controlling bacteria, fungi and yeasts while being compatible with most components in a formulation. Very low use levels make this product one of the most cost effective solutions on the market.
Chemical Composition
Isocil is comprised of two primary active compounds, 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one, in a dilute aqueous solution that permits easy and safe handling.
Active Ingredients (% WT/WT)
5-Chloro-2-methyl-4-isothiazolin-3-one (10.80%)
2-Methyl-4-isothiazolin-3-one ( 3.83%)
Total active ingredients (14.63%)
Inert Ingredients
Magnesium salts (As Mg(NO3)2 ( ~23% )
Water (~63%)
Typical Properties
Appearance : Clear Liquid
pH:2-4
Odor: Mild
Compatibility
Isothiazolinones are generally compatible with most components of industrial formulations. However, the presence of a few agents will cause degradation of the active ingredients (and therefore some care is necessary). Agents such as thiols, mercaptans, secondary amines, sulfides and other nucleophiles are to be avoided in formulations. Conditions of high heat for long periods of time ( > 50C) and pH above 9 will lead to loss of activity.
Biocidal Performance
Isocil isothiazolinone is a more cost effective biocide preservative due to the extremely low use levels required. While the specific use levels are application dependent, the following MIC values for isothiazoline activities are indicative of the effectiveness of the product.
Safety and Handling
Isothiazolinones at 14% active, are corrosive and potential skin sensitizers. As such, keeping these solutions away from the skin is essential. Due diligence must be maintained at all times while handling these materials. When working with Isocil, ensure that workers will not come in direct contact with the product. Proper selection of personal protective equipment is essential. Even if the slightest spill were to be absorbed onto a worker’s clothing, it may work its way through and cause a delayed skin burn. If significant aerosolization is expected, then the appropriate self contained breathing apparatus is required.
