TRANS-2-HEXENAL
Description
Trans-2-hexenal is a naturally occurring organic compound found in various fruits and vegetables, particularly in green leafy plants. This aldehyde contributes to the fresh, green aroma associated with newly cut grass and certain fruits. In skincare formulations, trans-2-hexenal serves multiple purposes due to its unique properties.
As an active ingredient, trans-2-hexenal exhibits antimicrobial and antifungal properties, making it valuable in products aimed at combating acne-causing bacteria and fungal skin infections. Its ability to inhibit microbial growth can help maintain product integrity and extend shelf life.
Trans-2-hexenal also functions as a fragrance ingredient, imparting a natural, fresh scent to skincare products. Its low molecular weight allows for easy penetration into the skin, potentially enhancing the delivery of other active ingredients.
In higher concentrations, trans-2-hexenal may act as a mild irritant, stimulating blood flow and potentially promoting cell turnover. However, formulators must carefully balance its concentration to avoid skin sensitization. Typically used in concentrations below 0.1%, trans-2-hexenal can be found in various skincare products, including toners, serums, and moisturizers, particularly those marketed as "natural" or "botanical" formulations.
