For businesses in the chemical, cosmetic, food, and pharmaceutical sectors, selecting the right raw materials is paramount. Propane-1,3-Diol (PDO), also known as Dihydroxypropane or Trimethylene Glycol, stands out as a highly versatile chemical intermediate. As a leading manufacturer and supplier of PDO in China, we understand the critical factors that influence purchasing decisions. This guide aims to provide R&D scientists, formulators, and procurement managers with essential insights into PDO grades and its diverse applications, empowering you to make informed decisions and secure high-quality products at competitive prices.

Propane-1,3-Diol is a diol, meaning it contains two hydroxyl (-OH) groups. Its unique chemical structure, with hydroxyl groups positioned at the 1 and 3 carbons of a three-carbon chain, imparts desirable properties such as excellent hygroscopicity, solvency, and low toxicity. These characteristics make it an indispensable ingredient across a wide spectrum of industries. When you look to buy Propane-1,3-Diol, understanding the available grades is the first step.

Understanding PDO Grades for Your Application

PDO is typically available in various grades to meet specific industry standards: Food Grade, USP Grade, and Industrial Grade. For those sourcing ingredients for the food and pharmaceutical industries, USP (United States Pharmacopeia) and Food Grade are critical. These grades ensure minimal impurities and adherence to strict safety regulations. For instance, if you're formulating dietary supplements or pharmaceutical excipients, sourcing USP grade PDO from a reputable supplier like ourselves is non-negotiable. Conversely, industrial applications such as polymer synthesis, paints, and coatings may utilize Industrial Grade PDO, which still offers high purity (often exceeding 99%) but may have slightly different specifications tailored for manufacturing processes.

Key Applications Driving Demand for PDO

The demand for Propane-1,3-Diol is driven by its performance in numerous applications:

  • Cosmetics and Personal Care: PDO is widely recognized for its excellent humectant properties, meaning it attracts and retains moisture. It's a popular ingredient in moisturizers, lotions, serums, and hair care products, providing hydration and improving skin feel. Its low irritation potential makes it suitable for sensitive skin formulations. When looking to buy cosmetic-grade PDO, consider suppliers who can provide detailed Certificates of Analysis (COA) to ensure product safety and efficacy.
  • Food Industry: In food applications, PDO serves as a solvent for flavors and colors, a humectant, and a plasticizer. It contributes to the texture and shelf-life of various food products. Manufacturers seeking reliable food-grade PDO can benefit from our bulk supply options.
  • Pharmaceuticals: The pharmaceutical industry utilizes PDO as a solvent, stabilizer, and excipient in various dosage forms, including ointments, suppositories, and oral solutions. Its compatibility with many active pharmaceutical ingredients (APIs) makes it a valuable intermediate. Procuring pharmaceutical-grade PDO from a trusted manufacturer ensures compliance and quality.
  • Industrial Manufacturing: PDO is a crucial monomer in the production of high-performance polymers like polytrimethylene terephthalate (PTT), used in textiles and carpeting. It also finds applications as a plasticizer, a component in paints and coatings, and an intermediate in pesticide formulations. For industrial users, understanding the performance requirements and sourcing competitive pricing from a reliable supplier is key.
