2,5-DIMETHYL-2-VINYLHEX-4-ENAL

Description

2,5-Dimethyl-2-vinylhex-4-enal is a synthetic fragrance ingredient commonly used in both skincare and haircare formulations. This colorless to pale yellow liquid compound belongs to the aldehyde family and is known for its fresh, green, and fruity odor profile with subtle floral undertones. Its molecular structure allows for excellent stability in various product types, making it a versatile choice for formulators.

In skincare and haircare applications, 2,5-dimethyl-2-vinylhex-4-enal serves primarily as a masking agent, helping to neutralize unpleasant odors associated with certain active ingredients or base formulations. It also contributes to the overall sensory experience of products, enhancing their olfactory appeal. Typically used in concentrations ranging from 0.01% to 0.1%, this ingredient is effective at low levels, minimizing the risk of skin sensitization.

While not an active ingredient in terms of skin or hair benefits, 2,5-dimethyl-2-vinylhex-4-enal plays a crucial role in product acceptability and user compliance. Its pleasant scent can improve the perceived efficacy of formulations, potentially leading to more consistent product use. However, as with all fragrance ingredients, patch testing is recommended for individuals with sensitive skin or known fragrance allergies.
