Description

2-(Octadecyloxy)-1,3-Propanediol is a high-purity, long-chain alkyl ether derivative of propanediol, serving as a versatile non-ionic surfactant and intermediate. This compound is valued for its ability to modify surface properties, acting as an effective emulsifier, dispersant, and viscosity modifier in complex formulations. It is essential for manufacturers in the personal care, coatings, and specialty chemical industries seeking to enhance product stability and performance.

Application

• As a key emulsifying agent and co-emulsifier in cosmetic and personal care products like creams, lotions, and sunscreens.
• As a dispersant and wetting agent in pigment preparations, coatings, and ink formulations to improve color consistency and stability.
• As a viscosity modifier and rheology control agent in industrial lubricants and functional fluids.
• As a chemical intermediate for the synthesis of more complex surfactants and specialty esters.
• As a softening agent and textile auxiliary in fiber processing and fabric treatment.
• In the formulation of release agents and mold lubricants for polymer and rubber processing.
• As a component in agricultural adjuvants to improve the spreading and adhesion of agrochemicals.
• Potential use in pharmaceutical formulations as an excipient for topical drug delivery systems.

Quality Control

Our 2-(Octadecyloxy)-1,3-Propanediol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting purity, assay, and impurity profiles is available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and performance. Keep away from strong oxidizing agents.
