Aldehyde C18

Aldehyde C18, commonly known as Oleic Aldehyde, is a classic aldehydic aroma chemical widely used in fine perfumery and cosmetic fragrance formulations. It is especially valued for its fresh, green, citrusy, and slightly fatty floral character, which adds natural brightness and elegance to fragrance compositions. Aldehyde C18 is an essential material for perfumers who aim to create realistic green, floral, and aldehydic accords.

In modern fragrance design, Aldehyde C18 is used to introduce freshness and lift while maintaining softness and balance. Unlike sharper aldehydes, C18 offers a smoother and more rounded profile, making it suitable for both fine fragrances and functional products. Its ability to blend seamlessly with floral, citrus, and green notes makes it a versatile and reliable ingredient in professional perfumery.

Chemical & Physical Characteristics

Aldehyde C18 is typically supplied as a clear to pale yellow liquid with good stability under recommended storage conditions. It has good solubility in alcohol and most fragrance solvents, which allows easy incorporation into perfume bases and finished products. The odor profile is described as green, citrusy, fatty, and floral, often reminiscent of crushed leaves, citrus peel, and fresh air.

Due to its aldehydic nature, Aldehyde C18 is generally used in low concentrations. Proper formulation knowledge is essential to achieve balance and avoid overpowering other fragrance components.
