Description

Ppg-36-Buteth-36 is a high-purity, non-ionic surfactant and emulsifier belonging to the class of polypropylene glycol butyl ethers. This versatile chemical intermediate is valued for its excellent solubilizing, wetting, and coupling properties in complex formulations. It is essential for manufacturers in the personal care, cosmetics, pharmaceuticals, and industrial cleaning sectors seeking reliable performance and consistent quality in their end products.

Application

• Personal Care & Cosmetics: Acts as a solubilizer for fragrances and essential oils, a coupling agent in clear gels, and a viscosity modifier in shampoos, creams, and lotions.
• Pharmaceuticals: Used as a solvent and co-solvent in topical formulations and as an excipient to enhance the solubility of active pharmaceutical ingredients (APIs).
• Industrial & Institutional Cleaning: Serves as a surfactant and coupling agent in heavy-duty degreasers, hard surface cleaners, and solvent-based cleaning systems.
• Coatings & Inks: Functions as a flow and leveling agent, as well as a solvent carrier, in various coating and printing ink formulations.
• Chemical Synthesis: Employed as an intermediate and reaction medium in the production of specialty chemicals and polymers.
• Agricultural Formulations: Used as an adjuvant and emulsifier in pesticide and herbicide concentrates to improve stability and application.
