Q1: What is the primary mode of action of Lonza Lonzaserve S10 Biocide?
A: Lonza Lonzaserve S10 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 and polymer systems.
Q2: In which types of formulations is Lonzaserve S10 typically used?
A: It is commonly incorporated into water-based industrial coatings, adhesives, construction chemicals, and water treatment systems where long-term preservation against microbial spoilage is required—particularly in applications sensitive to formaldehyde-releasing or isothiazolinone-based alternatives.
Q3: How should Lonzaserve S10 be dosed in a formulation?
A: Dosage depends on formulation requirements, challenge level, and regulatory context, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—to achieve effective preservation without compromising product stability or performance.
Q4: Is Lonzaserve S10 compatible with common surfactants and thickeners?
A: Yes, Lonzaserve S10 demonstrates good compatibility with a wide range of nonionic and anionic surfactants, as well as common rheology modifiers such as hydrophobically modified alkali-swellable emulsions (HASE) and cellulosic thickeners—though compatibility testing under actual formulation conditions is recommended.
