Hydroxypropyl Phosphate

Updated: 2026-09-13

Overview

Hydroxypropyl Phosphate is a chemical compound widely used in industrial applications due to its multifunctional properties. It serves as an emulsifier, stabilizer, and flame retardant, making it valuable in sectors such as textiles, coatings, and plastics. The compound is synthesized through the reaction of propylene oxide with phosphoric acid, resulting in a versatile product that enhances material performance. Its ability to improve stability and fire resistance has led to its adoption in various manufacturing processes.

Physical and Chemical Properties

Hydroxypropyl Phosphate typically appears as a colorless to pale yellow liquid, soluble in both water and organic solvents. Its chemical structure allows it to act as a bridge between hydrophilic and hydrophobic substances, making it an effective emulsifier. While specific data on melting and boiling points may vary, the compound is known for its stability under normal storage conditions. Its solubility profile and reactivity with other chemicals make it suitable for diverse industrial formulations.

Main Applications

The primary use of Hydroxypropyl Phosphate is in industrial processes where emulsification and stabilization are required. It is commonly found in textile treatments, where it enhances flame retardancy and fabric durability. Additionally, the compound is used in coatings and plastics to improve material properties such as adhesion and thermal resistance. Its versatility also extends to niche applications in specialty chemicals and research laboratories.

Safety and Storage

Handling Hydroxypropyl Phosphate requires adherence to safety protocols to minimize risks. It is essential to use personal protective equipment (PPE), including gloves and goggles, to prevent skin and eye contact. Storage should be in a cool, dry, and well-ventilated area, away from incompatible materials such as strong oxidizers. Proper labeling and containment measures are recommended to ensure safe handling and transportation.

B2B Procurement Guide

When procuring Hydroxypropyl Phosphate, buyers should verify the CAS number and purity specifications to ensure product suitability for their applications. Suppliers may offer technical data sheets (TDS) and material safety data sheets (MSDS) for reference. Bulk orders often qualify for discounts, making it cost-effective for large-scale industrial use. It is advisable to source from reputable manufacturers with a track record of quality and reliability.
