Nonionic triblock copolymer based on poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) architecture.
High molecular weight (approx. 10,300 g/mol) offering enhanced steric stabilization and viscosity-modifying capability.
Excellent water solubility across a broad temperature range with reversible thermogelling behavior above its cloud point.
Low toxicity profile and regulatory acceptance for use in pharmaceutical, cosmetic, and food-contact applications.
Effective emulsifier and solubilizer for hydrophobic actives, oils, and fragrances in aqueous formulations.
Stabilizer and viscosity enhancer in topical pharmaceutical gels and ointments.
Carrier and solubilizing agent for poorly water-soluble APIs in oral liquid formulations.
Emulsifier in high-performance personal care products including cleansing creams and moisturizers.
Template and structure-directing agent in nanoparticle synthesis and mesoporous material preparation.
Dispersant and wetting aid in agrochemical suspension concentrates (SCs) and microemulsions (MEs).
