7-HYDROXY-3,7-DIMETHYL-OCTANAL/INDOLE

Description

7-Hydroxy-3,7-dimethyl-octanal, also known as Hydroxycitronellal, is a versatile synthetic fragrance compound widely used in skincare and haircare formulations. This colorless to pale yellow liquid possesses a delicate, sweet floral scent reminiscent of lily of the valley. Its molecular structure allows for excellent fixative properties, enhancing the longevity of other fragrance components in a formulation.

In skincare applications, Hydroxycitronellal serves primarily as a masking agent, helping to neutralize unpleasant odors from active ingredients. It also contributes to the overall sensory experience of products, potentially improving user compliance. However, it's important to note that this ingredient can be a potential allergen for some individuals, particularly those with sensitive skin.

Indole, on the other hand, is a naturally occurring compound found in various essential oils and floral absolutes. In haircare formulations, Indole is valued for its ability to impart a rich, floral scent at low concentrations. It can enhance the complexity of fragrances, adding depth and naturalness to hair products. However, formulators must use Indole judiciously, as higher concentrations can produce undesirable fecal odors.
