Q1: What is the primary functional role of Pluronic RPE 3110 in formulations?
A: Pluronic RPE 3110 is a nonionic triblock copolymer surfactant designed primarily for emulsification, solubilization, and stabilization of oil-in-water systems. Its balanced hydrophilic-lipophilic character supports performance in demanding applications such as agrochemical concentrates, industrial cleaning, and specialty coatings.
Q2: How does Pluronic RPE 3110 compare to other Pluronic grades in terms of cloud point and temperature sensitivity?
A: Pluronic RPE 3110 exhibits a moderate cloud point—higher than low-EO variants like L-series but lower than high-EO grades such as F127—making it suitable for ambient-to-warm process conditions without premature phase separation. Its performance remains stable across typical formulation and storage temperatures encountered in industrial use.
Q3: Is Pluronic RPE 3110 compatible with common electrolytes and acidic or alkaline media?
A: Yes, this surfactant demonstrates good tolerance to moderate concentrations of salts and maintains functionality across a broad pH range (approximately pH 3–11), supporting its use in formulated systems containing fertilizers, corrosion inhibitors, or pH-adjusted cleaners.
Q4: What are typical dosage ranges for Pluronic RPE 3110 in commercial formulations?
A: Dosage depends on formulation requirements and target performance, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—in emulsion concentrates, solubilizing aids, and wetting agents.
Q5: Can Pluronic RPE 3110 be used in food-contact or pharmaceutical applications?
A: Pluronic RPE 3110 is not intended for direct food contact or pharmaceutical use. It is formulated and qualified for industrial, agricultural, and technical applications. Customers requiring regulatory-compliant surfactants for sensitive end uses should consult BASF’s portfolio of food-grade or pharma-qualified Pluronic grades.
