Biocides are formulated into the concentrates of products at anywhere between 20-25 times the end-use concentration. The preservative system must be soluble in the concentrate which may be a mixture of oil and water. The concentrate may then be stored anywhere between three months to one year. During this period of time, the biocide must remain active if it is to be efficacious when the product is used. There are many components in a metalworking fluid formulation that can deactivate certain types of biocides. For example, the presence of primary amines in many products rapidly deactivate isothiazolinone biocides, making this class of biocides unsuitable for use in the vast majority of metalworking fluid concentrates. 

It is soluble in water to about 4g/l it is more common to use this biocide as its sodium salt, improving its water solubility. It is incorporated into metalworking fluid concentrates at typically between 2 to 4% by weight. 

There are three major types of metalworking fluid straight (generally mineral oils), soluble (straight oils diluted with water and additives) and synthetic (water and addi-... 

Eisen et al. (1992) performed a cohort mortality study of 46 384 workers employed for three or more years before 1985 in three United States auto parts manufacturing facilities. Exposure to all three types of metalworking fluid (straight oils (insoluble or cutting oils), soluble oils (water-miscible or emulsifier oils) and synthetic oils (chemical fluids, containing ethanolamines)), the last two introduced in the 1940s, existed and no... 

Most alkanolamides are made with lauric-range (C12-C14) fatty acids or methyl esters. Increasing the carbon chain length decreases the water solubility, which is why higher-molecular-weight versions are used in oil-soluble applications (e.g. metalworking fluids). 

Dazomet s spectrum of activity is attractive for application of the compound in a number of industrial systems, e.g. as a slimicide in closed water circuits, paper machine systems, as a broad spectrum microbicide which prevents fungal blooms in metalworking fluid systems, or is suitable for the wet state preservation of a wide range of formulations, products for which the incorporation of a powder microbicide is necessary included. Compatibility with anionic, cationic and non-ionic surfactants increases formulation opportunities and improves effectiveness. However, there are limitations poor water solubility, instability, release of H2S and accordingly coloration by reaction with heavy metal salts. 

Random copolymers of ethylene oxide and propylene oxide containing more than 40 to 50 percent ethylene oxide are water soluble at room temperature. These liquid copolymers are used as functional fluids and lubricants, hydraulic fluids, and metalworking lubricants. Block copolymers—copolymers with "blocks" of oxyethylene followed by "blocks" of oxypropylene along the polymer chain—are soluble or dispersible in water and are a valuable and unique class of surface-active agents widely used as emulsion breakers of water-in-oil emulsions in the petroleum industry, as defoamers, and as low-sudsing detergents. 

These esters are recommended as lubricity additives for the metalworking market and are oil soluble water emulsif-iable. Especially as a replacement for mineral oil in cutting fluids and drawing compounds. STEPAN C-40 finds application in the formulation of aluminum beverage can drawing lubricants.
