Allyl Cyclohexyl Propionate brings a unique combination of properties, making it distinct among organic compounds often utilized in flavor and fragrance chemistry. The molecular formula stands as C12H20O2, showing a structure that merges an allyl group with a cyclohexyl propionate motif. The outcome is a compound with the ability to mimic the sweet, fruity nuances needed in food and cosmetic fragrances. Unlike simple esters, this one offers layered complexity, giving formulators material for full-bodied aromatic blends. The CAS number for reference aligns with regulatory databases, ensuring traceability and compliance during global transportation and sale.
This molecule looks straightforward on paper: a cyclohexyl ring adheres to an allyl moiety, both attached through a propionate ester linkage. By measuring density (around 0.97–0.99 g/cm³ at 20°C), manufacturers and users get clarity for dosing or preparing stock solutions, whether handling liquid or seeking to predict solubility in various carrier systems. Temperature changes shift the appearance: in most conditions, Allyl Cyclohexyl Propionate holds as a transparent fluid, not as a powder, flake, pearl, or crystal. With a molecular weight close to 196.29 g/mol, the compound remains mobile at standard laboratory and processing temperatures. At volumes exceeding a liter, the typical pale yellow tint may intensify, hinting at light sensitivity or gradual oxidation—a common story for unsaturated esters exposed to air.
Commercially, the compound arrives in drums or high-density polyethylene containers, liquid state preferred to allow for direct metering into reactors. Powder, flakes, or pearls are not practical forms due to volatility and stability factors. Producers list purity above 98%, with acidity and water content tightly controlled well below 0.5% to avoid unwanted hydrolysis during storage. Chemists in the field often test batches by GC or HPLC to assure conformity before using it as a raw material in perfumes or as a test substrate in olfaction panels. Its boiling point settles near 257°C, which grants safe headroom during process heating, though contact with open sparks or flames should be avoided due to the allylic function’s moderate reactivity, documented in material safety data sheets (MSDS) and by agencies referring to the HS Code 2915 70 00, indicating import obligations or taxation for cross-border shipments.
Even though the compound serves the flavor and fragrance industry, direct skin contact or inhalation over long periods can irritate, so working facilities post clear hazard signage and enforce good handling habits. Goggles, nitrile gloves, and local exhaust ventilation keep workspaces comfortable. From experience in laboratory and pilot plant settings, the most common exposure scenario follows from a leaky valve during drum transfers. Cleanup teams count on absorbent material like diatomaceous earth to prevent slips and spills reaching the drain. Documentation lists the material as harmful if ingested, referencing data from animal studies, though typical concentrations in finished products remain well below thresholds of health concern. Under transport, labeling aligns with GHS pictograms for flammable or hazardous materials, so every technician in the supply line knows what to expect.
Formulators choose Allyl Cyclohexyl Propionate for the full-bodied, fruity profile it brings to apple, pineapple, or pear bases. In soaps, it adds longevity, surviving the harshest lye environments where other esters fail. Aromatherapists employ minute doses, appreciating the depth it imparts alongside herbal, citrus, or balsamic notes. To minimize risk and optimize shelf-life, facilities now offer inert gas blanketing and dark, temperature-stable storage. Waste mitigation combines activated carbon scrubbing for exhaust and on-site neutralization to render any residues non-reactive before disposal. As industry moves towards greater traceability, manufacturers print lot-specific data on drum labels, connecting every batch back to source plant audits and quality records, supporting transparency and consumer trust demanded by regulators, especially those in the EU, US, and Asian markets. Advances in green chemistry push for biological or less energy-intensive synthesis, and research into renewable feedstocks, aiming for environmental stewardship without losing product efficacy.
