Description

Poly(Ethylene Glycol-Ran-Propylene Glycol) Monobutyl Ether is a high-performance, non-ionic block copolymer surfactant and functional fluid. This versatile chemical is valued for its excellent solubility, low toxicity, and tunable hydrophilic-lipophilic balance (HLB), making it a critical component in demanding formulations. It is essential for manufacturers in the personal care, pharmaceutical, agrochemical, and industrial cleaning sectors seeking reliable performance modifiers and solubilizers.

Application

• Personal Care & Cosmetics: Acts as a solubilizer for fragrances and essential oils, a coupling agent in clear gels, and a moisturizing agent in creams and lotions.
• Pharmaceuticals: Used as a solvent, co-solvent, and stabilizer in topical formulations, transdermal patches, and oral liquid preparations.
• Agrochemicals: Functions as a penetrant, wetting agent, and emulsifier in pesticide and herbicide formulations to enhance efficacy and stability.
• Industrial & Institutional Cleaning: Serves as a coupling agent and hydrotrope in heavy-duty degreasers, hard surface cleaners, and alkaline formulations.
• Coatings & Inks: Employed as a flow modifier, dispersant, and viscosity control agent in water-based systems.
• Textile Processing: Utilized as a lubricant, anti-static agent, and dyeing assistant in fiber treatment baths.
