ISOPENTANAL

Description

Isopentanal, also known as 3-methylbutanal, is a volatile organic compound with the molecular formula C5H10O. This colorless liquid aldehyde is characterized by its strong, fruity odor reminiscent of apple or peach. In skincare formulations, isopentanal serves multiple purposes, primarily as a fragrance ingredient and solvent.

The compound's low molecular weight allows for rapid evaporation, making it useful in products that require quick-drying properties. Isopentanal's ability to dissolve various substances enhances the overall formulation stability and helps in the uniform distribution of active ingredients.

In cosmetic applications, isopentanal is often employed in small concentrations due to its potent scent profile. It can mask unpleasant odors of other ingredients while imparting a fresh, fruit-like aroma to the final product. However, its use requires careful consideration, as some individuals may experience skin sensitization or irritation.

From a regulatory standpoint, isopentanal is generally recognized as safe (GRAS) by the FDA for use in food applications, which has influenced its acceptance in topical formulations. Nonetheless, formulators should adhere to recommended usage levels and conduct appropriate safety assessments to ensure product integrity and consumer safety.
