Vanilline Propylene Glycol Acetal stands out as a specialized compound created through the reaction of vanillin and propylene glycol. Also known by its systematic designation, this material draws interest from researchers and manufacturers for its unique scent profile, compatibility in formulations, and reliability as a raw material. It provides a sweet, creamy fragrance layered with warm vanilla notes, often adding depth and complexity in various applications. Chemically, this acetal presents a defined molecular structure, C13H18O4, with a molecular weight of 238.28 g/mol. These features carve out a distinct role in industries ranging from perfumery to specialty chemical manufacturing.
Crystal forms, powders, and flakes all exist within the range of Vanilline Propylene Glycol Acetal options, showing how diverse the raw material can be in its presentation. The typical appearance features off-white to pale-yellow crystalline solids, although finely milled powders and irregular flakes are not unusual across batches. Measured density hovers between 1.16 and 1.22 g/cm3, situating it among medium-density solid chemicals used in formulation and blending. Melting points generally settle around 70 – 75°C, and a gentle, almost creamy solubility appears in alcohols and propylene glycol itself. In clear liquid solutions, the acetal provides transparent and stable dispersions, simplifying the task of mixing in finished products.
The vanillin-derived backbone and acetal linkage make this compound chemically stable under neutral and mild acidic conditions, while strong acids tend to revert it toward its parent components. From a safety standpoint, the material does not behave like volatile solvents or aggressive chemicals, but it should never be dismissed as benign. Direct inhalation of dust or contact with mucous membranes may cause irritation; gloves, goggles, and dust masks have earned their place during handling, particularly in large-scale or industrial environments. The HS Code for shipment and customs classification commonly falls under 2912410000, which covers aromatic aldehydes and their derivatives, including chemically modified vanillin materials.
Vanilline Propylene Glycol Acetal earns trust due to consistent composition and aroma stability, making it a favored ingredient for perfumers chasing nuanced, long-lasting vanilla notes. Its solubility and stability enable seamless integration in everything from fine fragrances to technical blends used in detergents or air care products. This adaptability stretches into food-safe formulations under specific conditions, provided all relevant certification and purity requirements are met. In practice, users often prefer solid pearls and flakes as these present minimal dust while allowing simple weighing and metering. The solid forms can be milled or dissolved directly, depending on the desired end-use and manufacturing equipment on hand.
Experience shows that storage plays a critical role in maintaining the physical and olfactory integrity of Vanilline Propylene Glycol Acetal. Exposure to light, air, and moisture slowly degrades aroma quality and can lead to clumping or unwanted coloration. Keeping this material in tightly sealed containers away from direct sunlight and in dry, cool environments prevents most common quality losses. Some of the best results come from bulk packaging in lined cartons, drums, or moisture-barrier bags built to withstand warehouse fluctuations.
Chemical suppliers, safety professionals, and end-users all share responsibility for careful handling of Vanilline Propylene Glycol Acetal. Although classed as having low toxicity, it does not excuse carelessness. Spills involving large amounts require prompt clean-up to avoid slip hazards or localized exposure to dust clouds, especially in poorly ventilated work areas. Proper labeling, clear hazard statements, up-to-date Safety Data Sheets, and employee training programs contribute to a safer workplace. Waste or expired batches need to be disposed of in line with local hazardous waste guidelines, avoiding direct release into soil, drains, or waterways.
Ongoing attention to supply chain transparency makes a difference, particularly with synthetic flavor and fragrance raw materials like Vanilline Propylene Glycol Acetal. Traceable documentation, reliable quality control testing, and routine audits year after year raise standards for purity and sustainable production. Chemical buyers benefit from direct engagement with manufacturers who adhere to international standards, offer full batch testing data, and communicate openly about source materials used during synthesis. Implementing sustainable chemistry and waste minimization practices can reduce the environmental footprint, supporting both regulatory compliance and brand value.
