Description

1,2-Propanediol, 3-(Isooctadecyloxy) CAS NO 78145-84-3 is a high-purity, long-chain alkyl ether derivative of propylene glycol, valued for its unique combination of lipophilic character and surfactant properties. This specialty chemical serves as a critical non-ionic surfactant and solubilizing agent, enabling the formulation of stable emulsions and dispersions in demanding environments. It is essential for manufacturers in the personal care, coatings, and industrial lubricant sectors seeking to enhance product performance and stability.

Application

• Personal Care & Cosmetics: Acts as a non-ionic emulsifier and solubilizer in creams, lotions, and sunscreens, improving texture and active ingredient delivery.
• Coatings & Inks: Functions as a wetting and dispersing agent for pigments and fillers, enhancing color development and stability in solvent-based systems.
• Industrial Lubricants & Metalworking Fluids: Used as a surfactant and coupling agent to stabilize oil-water emulsions and improve lubricity.
• Agrochemical Formulations: Serves as an adjuvant and emulsifier in pesticide and herbicide concentrates, aiding in spray application and leaf adhesion.
• Textile Processing: Employed as a softening agent and lubricant in fiber treatments and dyeing processes.
• Polymer & Resin Modification: Acts as a plasticizer and compatibilizer to modify the flexibility and processing characteristics of certain polymers.
