UNDECADIENAL

Description

UNDECADIENAL is a potent aromatic compound naturally found in small quantities in certain citrus fruits, particularly grapefruits. This aldehyde is widely used in the fragrance and cosmetic industries due to its distinctive fresh, citrusy scent profile with green, waxy undertones. In skincare formulations, UNDECADIENAL serves multiple purposes beyond its olfactory properties.

As an active ingredient, it demonstrates antimicrobial activity, potentially helping to combat acne-causing bacteria and maintain a balanced skin microbiome. Its ability to penetrate the stratum corneum allows for enhanced delivery of other active ingredients in formulations. UNDECADIENAL also exhibits antioxidant properties, which may contribute to protecting the skin from environmental stressors and free radical damage.

In haircare products, UNDECADIENAL can impart a refreshing scent while potentially offering scalp-balancing benefits. Its molecular structure allows it to work synergistically with other ingredients, enhancing overall product efficacy. However, due to its potency, it is typically used in minute concentrations (0.01-0.1%) to avoid potential skin sensitization. As with any fragrant component, patch testing is recommended for individuals with sensitive skin or known fragrance allergies.
