UNDECENAL

Description

Undecenal, also known as undecylenal or undecylenic aldehyde, is a versatile organic compound used in both skincare and haircare formulations. This linear aldehyde, with the chemical formula C11H22O, is derived from castor oil through a process of pyrolysis and oxidation. Undecenal is characterized by its fresh, clean scent with subtle floral and citrus notes, making it a popular choice in fragrance compositions.

In skincare, undecenal serves multiple purposes. It acts as an effective antimicrobial agent, helping to combat acne-causing bacteria and fungal infections. Its mild antiseptic properties contribute to maintaining skin hygiene without causing irritation. Undecenal also functions as an emollient, improving skin texture and providing a smooth feel to products.

In haircare formulations, undecenal is valued for its ability to impart a pleasant fragrance and its potential to enhance the overall sensory experience of hair products. It may also contribute to the control of scalp microflora, potentially aiding in the management of dandruff and other scalp conditions.

Undecenal is generally well-tolerated and can be used in a wide range of concentrations, typically between 0.1% to 1% in finished products. Its multifunctional nature makes it a valuable ingredient in various personal care formulations.
