Dipropylene Glycol (DPG) is a versatile chemical with various applications, but not all grades are created equal. For industries like perfumery and cosmetics, using the correct grade of DPG is paramount to ensure product safety, quality, and performance. NINGBO INNO PHARMCHEM CO.,LTD., a prominent manufacturer in China, highlights the critical differences between Fragrance Grade DPG and Industrial Grade DPG.

Fragrance Grade DPG is specifically manufactured to meet the stringent requirements of the fragrance, cosmetic, and personal care industries. Key characteristics of this grade include high purity (typically exceeding 99.5%), a virtually odorless profile, and very low levels of impurities. These attributes are essential because DPG in these applications comes into direct contact with skin or is used in products where scent integrity is crucial. The low odor ensures that the DPG itself does not impart any unwanted scent, allowing the fragrance oils to shine through. Furthermore, its low toxicity and low skin irritation potential make it safe for topical application when formulated correctly.

Industrial Grade DPG, on the other hand, may contain a broader range of impurities and might have a more noticeable odor. While suitable for many industrial applications such as in the production of polyurethanes, resins, or as an antifreeze component, it is generally not recommended for use in products intended for skin contact or in high-end fragrances. The presence of impurities could potentially affect the scent profile, color, or safety of cosmetic and perfumery products.

Choosing the right grade of DPG is therefore critical. For those looking to buy DPG for fragrance compounding, perfumery, or personal care products, opting for Fragrance Grade DPG from a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD. is essential. This ensures that the ingredient will perform as expected, maintaining the purity of scents and the safety of finished goods. Understanding these distinctions helps formulators make informed decisions, securing the best possible ingredients for their product development, and ensuring compliance with industry standards for cosmetic ingredients.
