Q1: What is the primary function of BASF LS 104L in industrial formulations?
A: BASF LS 104L is a nonionic surfactant designed to provide effective wetting, dispersion, and emulsification—particularly in aqueous systems requiring low foam and good compatibility with electrolytes and other formulation components.
Q2: Is BASF LS 104L suitable for use in agrochemical concentrates?
A: Yes, it is commonly used in agrochemical SC (suspension concentrate) and EC (emulsifiable concentrate) formulations to stabilize active ingredients, improve spray droplet distribution, and enhance foliar adhesion—without compromising tank-mix compatibility.
Q3: How does BASF LS 104L perform under high-salinity or hard-water conditions?
A: It exhibits excellent stability and performance in the presence of multivalent ions and elevated salt concentrations, making it well-suited for formulations intended for use in challenging water quality environments.
Q4: Can BASF LS 104L be used in combination with ionic surfactants?
A: Yes, it is generally compatible with anionic and cationic surfactants when properly balanced in the formulation; however, compatibility testing is recommended to confirm colloidal stability and functional performance in specific end-use systems.
Q5: What are typical dosage ranges for BASF LS 104L in commercial formulations?
A: Dosage depends on formulation requirements and application method, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—based on total formulation mass.
