Dipropylene Glycol

(DPG) - Low Odor - Technical Grade

Dow® Chemical Product

Dipropylene glycol (DPG) is a clear, colorless, and odorless liquid that is commonly used as a solvent, humectant, and emulsifier in a wide range of industries. It is a derivative of propylene glycol and consists of two propylene glycol molecules connected by an ether bond. Dipropylene glycol is less hygroscopic than propylene glycol and has a higher molecular weight, which makes it more viscous and less likely to evaporate quickly.

In the fragrance and cosmetic industries, DPG is often used as a carrier for essential oils, perfumes, and other aromatic compounds, helping to dissolve and evenly distribute them in formulations. It helps improve the texture of creams, lotions, and other personal care products, while also enhancing their stability and shelf life.

Due to its low toxicity, DPG is considered safe for use in food and cosmetic products in regulated amounts. However, as with many chemicals, prolonged or excessive exposure may lead to skin irritation or sensitivity in some individuals. As defined by OSHA Hazard Communication Standard, this product is not known to be a hazardous chemical.

Applications and Uses for DPG:

Fragrance and Perfume Industry: DPG is commonly used as a carrier or solvent for essential oils and fragrance compounds. It helps to dilute and stabilize fragrances, making them easier to apply and ensuring that the scent lasts longer.
Cosmetics and Personal Care Products: DPG is a key ingredient in many personal care products such as lotions, creams, shampoos, deodorants, and soaps. It acts as a humectant (moisture-retaining agent), solvent, and emulsifier, helping to improve the texture, stability, and overall effectiveness of the product.
Fog Solution: dipropylene glycol is frequently found in fog juice / liquid, where it works as a base to create heavy low hanging fog vapor. Where as propylene glycol produces a lifting lighter fog vapor that tends to go towards the ceiling. Our low odor formula make it perfect for indoor fog applications.
Pharmaceuticals: In the pharmaceutical industry, dipropylene glycol is used as a solvent in medications, especially in liquid formulations like oral solutions, syrups, and injectable drugs. It helps dissolve active ingredients and stabilize the formula.
Industrial Applications: DPG is used in the manufacture of paints, coatings, cleaning agents, and lubricants. It functions as a solvent and helps improve the consistency and spreadability of these products.
Antifreeze and De-icing Products: While less common than propylene glycol, dipropylene glycol can also be used in some antifreeze and de-icing formulations due to its low freezing point and excellent solvency properties.
Food and Beverages: Though not as widely used as propylene glycol, DPG can be found in certain food and beverage products, where it serves as a solvent or stabilizer for flavorings, colorants, and other additives.
Textile and Leather Industry: DPG is used as a softener and finishing agent for textiles and leather products, contributing to a smooth texture and enhancing the durability and quality of the materials.
