Arctic Chemical Factory Supply 99.5% Min Dipropylene Glycol DPG CAS 25265-71-8 C6H14O3 Multi-Grade Industrial & Fragrance Cosmetic Solvent Wholesale

Arctic Chemical branded 99.5% dipropylene glycol (DPG) with CAS number 25265-71-8 is a premium polyol industrial solvent refined through multi-stage continuous rectification and impurity separation technology, supplied in industrial grade and low-odour fragrance cosmetic grade, widely exported to global perfume, personal care, coating, adhesive, resin synthesis and tobacco manufacturing industries.

Physically, this product is a clear, slightly viscous liquid with negligible peculiar odour and mild sweet flavour, possessing powerful hygroscopic capacity when exposed to humid air. It can be freely mixed with deionized water, ethanol, acetone, ethyl acetate and aromatic solvents without layering or precipitation, showing outstanding universal solubilizing and coupling capacity for polar and non-polar raw materials. Its high boiling point and stable slow volatilization characteristic make it an irreplaceable high-boiling point co-solvent for paint and ink formulations, delivering flat, flawless coating surface after drying without whitening, bubbles or orange peel texture defects that commonly occur with fast-evaporating low-boiling solvents.

Our strict GC-controlled 99.5% purity standard limits water, free acid and trace organic impurities to ultra-low ppm levels, which solves two major pain points for downstream manufacturers: residual odour interfering with perfume and cosmetic aroma, and acid impurities triggering side reactions during polyester resin polymerization. The specially customized low-odour cosmetic grade undergoes secondary deodorization and deep purification, with zero interference on delicate perfume notes, widely adopted by fragrance factories as carrier solvent for essential oil, artificial flavour and reed diffuser formulations. In skin care and hair care cosmetics, DPG acts as mild humectant to boost product moisturizing performance while reducing formula irritation index, suitable for facial lotion, sunscreen, shampoo and body wash production.

In coating and printing workshops, DPG is compounded with other ester and alcohol solvents to prepare slow-drying mixed thinner for nitrocellulose paint, PU varnish and gravure printing ink, improving ink leveling property and printing pattern fineness. Resin factories use high-purity DPG as monomer raw material to synthesize flexible unsaturated polyester resin and non-toxic plasticizer, enhancing resin toughness and low-temperature resistance. For adhesive production, it adjusts PU glue slurry viscosity and extends glue open time to simplify construction operation. Tobacco processing enterprises add DPG as exclusive humectant raw material to lock tobacco internal moisture, reduce dry burning irritation and smooth smoke taste during smoking.
