2,4-DIMETHYL-3-CYCLOHEXENE CARBOXALDEHYDE

Description

2,4-Dimethyl-3-cyclohexene carboxaldehyde, also known as Ligustral or Triplal, is a synthetic fragrance ingredient widely used in cosmetics and personal care products. This colorless to pale yellow liquid compound has a distinct floral, green, and aldehydic odor profile, reminiscent of fresh cucumber and lilac notes.

The molecular structure of this aldehyde contributes to its stability and longevity in formulations. It is particularly valued for its ability to impart a natural, fresh scent to products without overwhelming other fragrance components. In skincare and cosmetic applications, 2,4-dimethyl-3-cyclohexene carboxaldehyde is often used in concentrations ranging from 0.1% to 1%.

This ingredient is known for its excellent fixative properties, helping to extend the overall fragrance performance of a product. It blends well with various other fragrance materials, including floral, woody, and citrus notes. While primarily used for its olfactory properties, some formulators also appreciate its subtle cooling effect on the skin.

Safety assessments have shown that 2,4-dimethyl-3-cyclohexene carboxaldehyde is generally well-tolerated when used at recommended concentrations. However, as with any fragrance ingredient, patch testing is advisable for individuals with sensitive skin or known fragrance allergies.
