DECANAL

Description

Decanal, also known as n-decanal or capric aldehyde, is a potent aromatic compound naturally occurring in various citrus fruits and essential oils. This linear aldehyde consists of a ten-carbon chain with a characteristic aldehydic functional group, contributing to its unique olfactory profile. In skincare formulations, decanal serves multiple purposes, primarily as a fragrance ingredient and potential active component.

The compound exhibits antimicrobial properties, making it valuable in preservative systems for cosmetic products. Research suggests decanal may possess antioxidant capabilities, potentially offering protection against free radical damage in the skin. Its lipophilic nature allows for easy penetration into the stratum corneum, enhancing its efficacy in topical applications.

Decanal is commonly used in concentrations ranging from 0.1% to 1% in skincare products, depending on the desired effect and formulation type. It imparts a fresh, citrusy scent with subtle floral undertones, often employed to mask less pleasant odors in cosmetic preparations. While generally well-tolerated, decanal may cause skin sensitization in some individuals, necessitating patch testing before widespread use. Formulators should consider its volatility and potential for oxidation when incorporating decanal into skincare products.
