Dipropylene Glycol (DPG) | Solvent | CAS# 25265-71-8

• Origin: Singapore/Thailand
• CAS Number: 25265-71-8

Dipropylene Glycol (DPG) It is a type of glycol commonly used in industry as a solvent, carrier, and dissolution aid. The product has CAS 25265-71-8, chemical formula... CH₁₄O₃DPG, which typically exists as a clear liquid with a certain viscosity, good solubility, and low volatility, is completely miscible with water and compatible with many organic solvents. Therefore, it is widely used in fragrance formulations, cosmetics, personal care products, paints and inks, plastics, and many other industrial fields.

In particular, DPG is highly regarded in the industry. perfumes and fragrances Thanks to its ability to dissolve many fragrance components, along with its relatively stable properties and low volatility, it is one of the ingredients commonly used as a base and carrier for fragrance formulations.

1. Key characteristics of Dipropylene Glycol

DPG possesses many properties suitable for formulations requiring a stable solvent and good solubility. This chemical is a clear liquid with relatively high viscosity, completely soluble in water, and compatible with many organic solvents. Its high boiling point and low volatility allow DPG to maintain its role as a solvent in formulations for longer periods compared to more volatile solvents.

In fragrance formulations, DPG is often chosen because of its very low base odor, minimizing its impact on the scent characteristics of the final product. At the same time, its solubility and carrier properties help to disperse fragrance components more effectively, contributing to a more consistent formulation.

2. What is DPG used for?

Dipropylene glycol (DPG) is primarily used as a solvent and carrier in many chemical formulations. In the fragrance industry, DPG helps dissolve essential oils, fragrance oils, and scent compounds, resulting in more uniform and stable formulations. Additionally, DPG is used in cosmetics and personal care products as a solvent, humectant, and viscosity modifier.

On an industrial scale, DPG is also used in the production of plastics, plasticizers, paints, coatings, printing inks, and some functional fluids.

4. Applications of Dipropylene Glycol in the Fragrance Industry

This is one of the important applications of DPG. In the production of perfumes, perfume oils, alcohol-free perfumes, fragrance products, and air care products, DPG can act as a solvent and carrier for fragrance components.

Thanks to its good solubility and low volatility, DPG helps to disperse and maintain fragrance components in formulations, while also contributing to product homogeneity. DPG is also used in fragrance formulations for cosmetics, personal care products, and space fragrances.
