Hydroxycitronellol

What is Hydroxycitronellol?

Hydroxycitronellol is a synthetic aliphatic alcohol used exclusively as a perfuming agent in cosmetics. It features a branched hydrocarbon chain with a hydroxyl group, delivering a light, green floral aroma reminiscent of lily-of-the-valley blossoms. This ingredient appears as a colorless to pale yellow liquid and integrates into formulations like perfumes, creams, shampoos, and body washes at trace levels. In products, it contributes specific scent notes, blends with other aroma compounds to achieve harmony, and conceals undesirable base smells from raw materials. Its volatility aids in creating diffusion-balanced fragrances that evolve on the skin, enhancing the sensory quality without overpowering other elements.
