Q1: What is the primary mode of action of Lonzaserve 210 Biocide?
A: Lonzaserve 210 Biocide functions primarily through membrane disruption and interference with essential microbial metabolic processes, delivering broad-spectrum efficacy against bacteria, yeasts, and molds in industrial water-based systems.
Q2: In which types of formulations is Lonzaserve 210 typically used?
A: It is commonly incorporated into water-based industrial products such as metalworking fluids, latex paints, adhesives, construction chemicals, and cleaning concentrates—where long-term preservation against microbial spoilage is required during storage and use.
Q3: Is Lonzaserve 210 compatible with common surfactants and thickeners?
A: Yes, it demonstrates good compatibility with a wide range of anionic, nonionic, and amphoteric surfactants, as well as typical rheology modifiers including cellulose ethers and associative thickeners—though compatibility testing under actual formulation conditions is recommended.
Q4: How should Lonzaserve 210 be added to a formulation?
A: It is generally added during the cool-down phase or post-emulsification stage to avoid thermal degradation, and should be dispersed uniformly using low-shear mixing. Dosage depends on formulation requirements but typically ranges from 0.1% to 2% by weight of the final product.
