Understanding the fundamental chemistry of the raw materials you use is essential for optimizing product performance and innovation. Dipropylene Glycol (DPG), with its CAS number 110-98-5, is a chemical compound whose unique molecular structure dictates its valuable properties. As a leading supplier of high-quality DPG, we aim to provide insights into the science that makes this glycol so indispensable across industries.

DPG is an organic compound that belongs to the glycol family, specifically a diol, characterized by the presence of two hydroxyl (-OH) groups. Its chemical formula is C6H14O3. Structurally, it is a mixture of three isomers: 4-oxa-2,6-heptanediol, 2-(2-hydroxypropoxy)-propan-1-ol, and 2-(2-hydroxy-1-methylethoxy)-propan-1-ol. This structural complexity contributes to its versatile performance characteristics, including its high boiling point (around 230-231°C) and its ability to remain liquid over a wide temperature range, with a freezing point of approximately -40°C. The molecular weight is around 134.17 g/mol.

One of DPG's most significant attributes is its exceptional solvency. The presence of both ether linkages and hydroxyl groups makes it miscible with water and many organic solvents. This amphiphilic nature allows it to dissolve a broad spectrum of substances, including polar compounds like salts and sugars, as well as non-polar materials like oils and resins. This makes it an ideal solvent and carrier in applications ranging from cosmetic formulations and fragrances to industrial coatings and inks. For those looking to buy Dipropylene Glycol, its solvency power is a primary driver for its selection.

The low toxicity profile of DPG is another critical chemical property. Unlike some other glycols, DPG exhibits very low oral and dermal toxicity. This is particularly advantageous for its use in cosmetic, personal care, and potentially even food-related applications (though specific grades and regulations apply). Its minimal skin irritation and low vapor pressure also contribute to its safe handling and use in various manufacturing environments. As a responsible Dipropylene Glycol manufacturer, we ensure our product adheres to stringent purity standards, reinforcing these safety aspects.

Furthermore, DPG's hygroscopic nature – its ability to attract and hold water molecules – makes it an effective humectant. This property is leveraged in skincare products to help maintain skin hydration. In industrial settings, this characteristic can also be beneficial for controlling moisture in certain formulations or materials.

Understanding these chemical properties allows formulators and manufacturers to leverage DPG's capabilities to their fullest. Whether it's ensuring the stability of a fragrance, improving the flexibility of a resin, or achieving the desired texture in a cosmetic, the chemistry of Dipropylene Glycol provides the foundation for superior product performance. As a trusted supplier, we are committed to providing DPG of the highest purity to help you achieve your formulation and manufacturing goals.
