Dowicil 75 Preservative 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride Dow Chemical Preservatives / Biocides / Fungicides ADHESIVE >> Water-based DOWICIL 75 Preservative is the Dow product designation for 1-(3-chloroallyl)-3,5,7-triaza-1- azoniaadamantane chloride combined with a stabilizer (sodium bicarbonate). It is designed to provide highly effective antimicrobial activity in aqueous formulations, including adhesives, paints, construction materials, latexes, and detergents, to name just a few. Adhesives based on starches, latexes, proteins, and natural or synthetic gums are subject to attack by bacteria and fungi during manufacturing, storage, and use. Microbial attack may cause loss of adhesive properties, changes in viscosity, pH drop, and/or odor formation. DOWICIL 75 can be used to preserve adhesives with no adverse effects on formulation properties. Starch-based adhesives used to make corrugated board are a special case because of their alkaline pH. Only a small group of organisms has adapted to this harsh environment, but they can cause significant problems. DOWICIL 75 has been shown to provide effective protection of these adhesives for up to two weeks when used at concentrations between 0.03 and 0.05% by weight (300 - 500 ppm). Effective at low concentrations DOWICIL 75 Preservative provides highly effective antimicrobial activity at low concentrations – typically 0.01 to 0.27% by weight in formulations. You get maximum antimicrobial effectiveness with minimum potential for undesirable effects on your formulation. Broad-spectrum activity A formulation preserved with DOWICIL 75 is protected against a wide variety of bacteria and fungi. DOWICIL 75 Preservative is particularly effective against Pseudomonas aeruginosa, the most common spoilage organism. The preservative is also effective against other frequently encountered organisms, such as Bacillus subtilis, Aspergillus niger, and numerous others. Excellent formulation compatibility DOWICIL 75 Preservative has been shown to be compatible with many formulation systems. Anionic, cationic, and nonionic surfactants will not inactivate DOWICIL 75. Further, DOWICIL 75 Preservative has very little effect on the surface tension of aqueous systems, and it has no solubilizing-coupling action. Cost-effective Because it provides highly effective antimicrobial activity at low concentrations, DOWICIL 75 is one of the most cost-effective aqueous system preservatives available. In many applications, such as acrylic latex paints, it’s difficult to find equivalent antimicrobial protection at a cost lower than that of DOWICIL 75 Preservative. High water solubility Because spoilage microorganisms must have water for metabolic processes, they will thrive only in the aqueous phase of a formulation. DOWICIL 75 Preservative is highly soluble in water, and has very low solubility in oils and organic solvents. So DOWICIL 75 Preservative will stay in the water phase of a formulation, where it’s needed. Wide pH latitude Most microorganisms require an environment with a pH between 5 and 9. Occasionally, certain species will survive at a pH as low as 2 or as high as 12. The antimicrobial activity of DOWICIL 75 Preservative has been demonstrated in formulations with a pH ranging from 2 to 12.5. That means you get good pH compatibility with almost any formulation, plus a margin of assurance in the event of moderate pH drift by the formulation over time. 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride combined with a stabilizer (sodium bicarbonate). Used as preservative in water based adhesives based on starches, latexes, proteins, and natural or synthetic gums. Provides highly effective antimicrobial activity. Offers efficiency at low concentrations, broad-spectrum activity and wide pH latitude.
