Myrcene, with the CAS number 123-35-3, is a synthetic aroma chemical commonly used in perfumery for its fresh, green, and slightly fruity character. It is often found in formulations that aim to evoke natural scents, as it can mimic the aroma of certain essential oils. Myrcene is typically used in the top or middle notes of a fragrance, contributing to the overall brightness and complexity of the scent profile. In addition to its olfactory properties, myrcene is also noted for its potential to enhance the diffusion of other fragrance ingredients, making it a valuable component in many compositions. From a safety perspective, myrcene is subject to regulatory scrutiny, and perfumers should be aware of any applicable IFRA restrictions when formulating with this ingredient. While it is not commonly listed as a major allergen, it is always advisable to consider the overall allergenic potential of a fragrance blend, especially in products intended for sensitive skin. — AI-generated summary, 2026-09-02.

Colorless or very pale straw-colored mobile liquid. It may acquire a pale amber color and it may eventually resinify (polymerize) upon exposure to daylight and air.
Insoluble in water, soluble in alcohol, miscible with most perfume oils.
Sweet-balsamic-resinous gum odor of poor tenacity. The odor of the purified Myrcene is refreshing, almost citrusy, but warm-balsamic, and ethereal-sweet.
The taste is sweet-balsamic-herbaceous at concentrations below 10 ppm. Higher concentrations tend to give pungency, bitterness or gassy taste.
This terpene finds use in perfume formulations where its spicy-balsamic and refreshingly light character introduces desirable notes in citrus and spice colognes, or it finds more extensive use in masking odors for industrial purposes, mainly because of its low cost. It is also used as a component of artificial essential oils, and as a fresh note in common household products.
Trace amounts of Myrcene are used in flavor compositions such as root-beer, citrus, coriander, fruit-complexes, etc. The concentration in the finished product will normally be from 0.5 to 5 ppm.
Produced by thermal isomerization of beta-Pinene (pyrolysis).
