Citronellal, also recognized as Rhodinal and identified by CAS 106-23-0, is celebrated in the fragrance industry not just for its chemical structure but predominantly for its distinct olfactory character. Understanding the citronellal olfactory profile is fundamental to appreciating its extensive use in perfumery and other scented products.

The primary descriptor for Citronellal's aroma is a strong, sweet grass scent. This characteristic note is what makes it so recognizable and versatile. It possesses a fresh, lemony, and slightly green quality, often reminiscent of lemongrass itself. This makes it an excellent component for recreating or enhancing citrus and green notes in fragrance compositions.

Within the perfumer's palette, Citronellal serves multiple roles. It is frequently used to impart a vibrant, lemony freshness, particularly in top and middle notes. Its ability to blend seamlessly with floral ingredients, such as rose and muguet (lily of the valley), allows for the creation of complex and layered accords. The citronellal uses in perfumery are vast, ranging from creating classic floral bouquets to adding a bright, clean edge to modern scents.

Beyond its primary scent contribution, Citronellal also acts as a fixative and a modifier. As a fixative, it helps to prolong the diffusion of other, more volatile fragrance components, ensuring the scent lasts longer on the skin. As a modifier, it can subtly alter or enhance the overall character of a fragrance, adding depth and complexity.

The citronellal chemical properties, such as its molecular formula (C10H18O) and its physical state as a clear, light yellow liquid, are important for formulation. However, it is the citronellal aroma that dictates its primary applications in creating appealing scents for perfumes, cosmetics, soaps, and air fresheners.

Moreover, Citronellal's pleasant aroma is complemented by its functional properties, such as its efficacy as an insect repellent and its use as a flavoring agent. This multifaceted nature ensures its continued relevance across various consumer product categories.

For manufacturers seeking to leverage its unique scent profile, sourcing high-quality Citronellal from reliable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. is crucial. The consistent quality and accurate olfactory description of Citronellal are key to successful fragrance development and customer satisfaction.
