• ⚗️Uses — Octahydrocoumarin is highly valued in the fragrance industry for its unique ability to add depth, warmth, and a comforting sweetness to fragrance mixtures. Its uses span a wide array of applications, including:

  1. Perfumes and Eau de Toilettes: It is often incorporated into the base notes of perfumes to provide a lasting, warm foundation that complements floral, citrus, or spicy top and middle notes, enhancing the overall complexity and appeal of the scent.

  2. Personal Care Products: In shampoos, conditioners, lotions, and body washes, octahydrocoumarin adds a subtle, warm sweetness that enriches the sensory experience of these products, making them more inviting and enjoyable to use.

  3. Candles and Home Fragrances: Its comforting aroma makes it a popular choice for candles, diffusers, and room sprays, creating a cozy and welcoming atmosphere in indoor spaces.

  4. Ambient Scenting and Air Care Products:Used in air fresheners and scent marketing products, octahydrocoumarin can imbue environments with a warm, comforting presence, enhancing mood and customer experience in commercial settings.

  5. Soap Making: Its stability and appealing scent profile make it a favorite for artisanal and commercial soap making, adding a touch of warmth and sophistication to the final product. Through these diverse applications, octahydrocoumarin plays a pivotal role in fragrance formulations, contributing to the creation of memorable, multi-dimensional scents that resonate with a broad audience.

To write an overview of the molecule "octahydrocoumarin" (CAS number: 4430-31-3), including all chemical data, smell, and flavor, we can synthesize insights from related research and studies on coumarin and its derivatives, since direct references to octahydrocoumarin specifically are limited. However, some insights can be extrapolated based on the characteristics and behaviors of closely related compounds within the same chemical family.

Chemical Data

Octahydrocoumarin, a derivative of coumarin, is part of a family of compounds known for their presence in many plants, contributing to chemical protection against predators. Coumarin itself is known for its colorless, crystalline solid form with a bitter taste and sweet vanilla-like odor. It exhibits anti-coagulant, anti-fungal, anti-tumor, and anti-inflammatory properties, which are used in treating various skin diseases. The fluorescence intensity and emission wavelength of coumarin derivatives, including octahydrocoumarin, can be influenced by pH due to internal charge transfer (ICT) effects in various solvents of differing polarity (Huda et al., 2021).

Smell and Flavor

While specific data on octahydrocoumarin's smell and flavor are not directly available, coumarin is well-known for its pleasant sweet-herbaceous and cherry flower-like odor. This characteristic is common among coumarin derivatives and contributes significantly to their use in flavoring and fragrance applications. Dihydrocoumarins, which are related to octahydrocoumarin, play an important role as flavor and fragrance compounds, and can be prepared efficiently from o-hydroxycinnamaldehydes in a mild, atom-economic process (Zeitler & Rose, 2009).

Given the structural similarities and chemical properties, it's plausible that octahydrocoumarin shares the vanilla-like, sweet-herbaceous scent profile characteristic of its coumarin base, with potential variations depending on specific substitutions and modifications in its structure. These compounds' flavor and aroma profiles make them valuable in the creation of synthetic fragrances and flavors, where they can impart depth, warmth, and complexity to various products.

This overview provides a starting point for understanding octahydrocoumarin, drawing on the broader context of coumarin and its derivatives' chemical properties, smell, and flavor contributions. Further specific studies on octahydrocoumarin would offer more detailed insights into its unique characteristics.
