Description

Tetrapropylene Glycol CAS NO 24800-25-7 is a polyether glycol derived from propylene oxide, valued for its excellent solvency and humectant properties. This versatile chemical intermediate is crucial for formulators seeking to enhance product performance, particularly in applications requiring controlled viscosity and moisture retention. It is an essential raw material for manufacturers in the polyurethane, personal care, and specialty chemical industries.

Application

• As a key polyol component in the production of flexible polyurethane foams and elastomers.
• As a humectant and solvent in personal care products, cosmetics, and pharmaceutical formulations.
• As a chemical intermediate for synthesizing plasticizers, lubricants, and specialty surfactants.
• As a viscosity modifier and carrier fluid in functional fluids, hydraulic liquids, and industrial lubricants.
• In the formulation of inks, dyes, and coatings where solvency and flow properties are critical.
• As a reaction medium or processing aid in various organic synthesis and polymerization processes.

Quality Control

Our Tetrapropylene Glycol is produced under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing to verify key parameters such as purity, hydroxyl value, and water content. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
