When formulating captivating fragrances, the choice of solvent is paramount. Two commonly used glycols in the perfumery industry are Dipropylene Glycol (DPG) and Propylene Glycol (PG). While both serve as effective diluents and carriers for fragrance oils, they possess distinct properties that make them suitable for different applications. Understanding these differences is crucial for any manufacturer aiming to achieve the desired scent profile, longevity, and overall product quality. As a leading supplier of high-purity chemical ingredients, NINGBO INNO PHARMCHEM CO.,LTD. offers insights into selecting the right glycol for your needs.

Dipropylene Glycol (DPG), with the CAS number 110-98-5, is a colorless, low-odor, and viscous liquid. Its key advantage in perfumery lies in its low volatility and high boiling point. This characteristic makes it an excellent fixative, meaning it helps to moderate the evaporation rate of fragrance oils. For a perfumer, this translates to a more stable and longer-lasting scent on the skin, allowing the top, heart, and base notes to unfold gracefully over time. DPG's uniform isomer distribution and excellent quality ensure that it does not interfere with the delicate aroma of the fragrance oils, preserving the perfumer's original intent. If you are looking to buy dipropylene glycol fragrance grade for superior performance, consider sourcing from a reputable manufacturer in China.

Propylene Glycol (PG), on the other hand, is a simpler glycol with a lower molecular weight and a more pronounced odor, though still relatively mild. While it is a good solvent and humectant, its higher volatility means fragrance notes may dissipate more quickly compared to DPG. PG is often used in applications where a faster evaporation rate is desired or when cost is a primary consideration. However, for premium fragrances requiring extended scent presence and complexity, DPG typically offers superior results.

The decision between DPG and PG often hinges on the specific requirements of the fragrance. For instance, if you are creating reed diffusers or potpourri where a slow and steady release of scent is desired, DPG is the preferred choice. Its ability to bind well with fragrance oils and release them gradually ensures a consistent aroma experience. For incense making, a common recommendation is to use a 2:1 ratio of DPG to fragrance oil to ensure proper binding and slow burning. When seeking a dependable dipropylene glycol supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. provides high-purity options that meet stringent industry standards.

For formulators prioritizing longevity, scent stability, and a smooth diffusion profile, sourcing high-quality DPG is a strategic decision. Purchasing DPG from an established manufacturer ensures consistent quality, competitive price points, and a reliable supply chain. Whether you are developing fine perfumes, personal care products, or even specific industrial applications requiring a high-performance solvent, understanding the nuances between DPG and PG is key.
