2,6,6-TRIMETHYL-2-CYCLOHEXENE-1-ACETALDEHYDE

Description

2,6,6-Trimethyl-2-cyclohexene-1-acetaldehyde, also known as β-Homocyclocitral, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This colorless to pale yellow liquid compound belongs to the aldehyde family and possesses a distinct floral, green, and fruity odor profile with subtle woody undertones.

In skincare formulations, this ingredient primarily functions as a fragrance enhancer, contributing to the overall sensory experience of the product. It is often incorporated in low concentrations due to its potent scent. While not directly involved in skin benefits, its pleasant aroma can improve user compliance and satisfaction with skincare routines.

2,6,6-Trimethyl-2-cyclohexene-1-acetaldehyde has a molecular weight of 180.28 g/mol and is soluble in various cosmetic solvents. It is stable under normal storage conditions but may oxidize when exposed to air. This ingredient is generally considered safe for use in cosmetics when formulated at appropriate levels, typically below 0.1% in leave-on products and 0.5% in rinse-off products.

Formulators should be aware of potential skin sensitization in some individuals and consider alternative fragrance options for products targeted at sensitive skin types.
