TETRAHYDRO-METHYL-METHYLPROPYL)-PYRAN-4-OL

Description

Tetrahydro-methyl-methylpropyl-pyran-4-ol, also known as Hydroxycitronellal, is a versatile synthetic fragrance ingredient commonly used in skincare and cosmetic formulations. This colorless to pale yellow liquid possesses a delicate floral scent reminiscent of lily of the valley, making it a popular choice for adding a fresh, clean aroma to various products.

In skincare applications, Hydroxycitronellal functions primarily as a masking agent, helping to neutralize unpleasant odors associated with active ingredients. Its mild, pleasant scent can enhance the overall sensory experience of skincare products without overpowering other fragrances. While not an active ingredient itself, it contributes to product stability and user satisfaction.

It's important to note that Hydroxycitronellal is a potential allergen and must be used judiciously in formulations. The European Union requires its declaration on product labels when concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products. Formulators should be aware of regulatory limits and conduct appropriate safety assessments when incorporating this ingredient.

Despite its synthetic nature, Hydroxycitronellal is biodegradable and considered to have a low environmental impact when used in typical cosmetic concentrations.
