TRANS-2-DECENAL

Description

TRANS-2-DECENAL is an organic compound belonging to the class of unsaturated aldehydes. It is a colorless to pale yellow liquid with a distinctive, powerful green and fatty odor reminiscent of fresh cilantro or orange peel. In haircare formulations, TRANS-2-DECENAL serves as a fragrance ingredient, imparting a fresh, natural scent to products.

This compound is naturally occurring in various essential oils and foods, including cilantro, orange peel, and rice. Its use in haircare products is primarily for its aromatic properties rather than direct hair benefits. TRANS-2-DECENAL is typically used in very low concentrations due to its potent odor profile.

In formulations, it can contribute to masking unpleasant base odors of other ingredients while adding a natural, herbal note to the overall fragrance composition. It is often combined with other fragrance components to create complex, layered scents in shampoos, conditioners, and styling products.

While generally considered safe for cosmetic use at low concentrations, formulators should be aware of potential skin sensitization in some individuals. Proper dosage and adherence to regulatory guidelines are essential when incorporating TRANS-2-DECENAL into haircare formulations.
