Aldehyde C9 Overview

What is Aldehyde C9?

Aldehyde C9, with the chemical formula C9H18O and the CAS number 124-19-6, is a linear aldehyde that boasts a diverse range of applications, particularly in the fragrance and flavor industries. Its scent is often described as citrus-aldehydic, with prominent notes of sweet orange alongside hints of waxy, green nuances. This complexity makes it a popular choice for perfumers seeking to create vibrant, uplifting scents.

Where Does Aldehyde C9 Come From?

Natural occurrence of Aldehyde C9 is notable, as it can be found in several essential oils, including lemon oil and rose oil. Additionally, it can be isolated from cinnamon and other natural sources. However, for commercial applications, synthetic production is favored due to the consistency and availability of the ingredient.

Characteristics of Aldehyde C9

Odor Profile

One of the most striking aspects of Aldehyde C9 is its strong and distinct scent. The fragrance profile combines the refreshing attributes of citrus with an underlying waxy quality that sets it apart. When used in formulations, Aldehyde C9 serves to enhance and brighten other scents, making them more pronounced. This quality is particularly useful for enhancing floral and fruity notes, giving perfumes a lively touch.

Concentration and Usage

Due to its powerful olfactory properties, Aldehyde C9 is typically used in very low concentrations, often suggested to be diluted to a ratio of 1% in formulations. This dilution helps to control the intensity of its scent and ensures that it integrates seamlessly with other fragrance components.

Storage Recommendations

To maintain the integrity and potency of Aldehyde C9, it should be stored in a cool, dark place. This not only prolongs its shelf life but also prevents any undesirable changes to its chemical composition that could occur due to light or heat exposure.

Usage in Cosmetics and Personal Care

Beyond perfumery, Aldehyde C9 finds its way into cosmetic products. It serves to impart a fresh scent to lotions, shampoos, and body washes, elevating the overall sensory experience of the items. The evocative nature of its scent profile makes it a desirable ingredient in products aimed at creating a relaxing or uplifting ambiance.

Flavoring in Food and Beverage

Interestingly, Aldehyde C9 is also utilized within the food and beverage industry. Although it plays a minimal role compared to its applications in fragrance, it can contribute to the flavor profiles of certain products, particularly in creating citrus-like flavors that are perceived as refreshing and clean.
