DIMETHYLSPIROUNDECANONE

Description

Dimethylspiroundecanone, also known as Spiromusk, is a synthetic musk fragrance ingredient commonly used in skincare and personal care products. This colorless to pale yellow liquid possesses a clean, woody-musky odor with subtle floral undertones. Its molecular structure features a spirocyclic ring system, contributing to its unique olfactory profile and stability.

In skincare formulations, dimethylspiroundecanone serves primarily as a fragrance fixative, enhancing the longevity of scents in various products. It exhibits excellent stability in both acidic and alkaline environments, making it versatile for use in a wide range of cosmetic applications. This ingredient demonstrates good solubility in common cosmetic solvents and oils, facilitating easy incorporation into diverse formulations.

Dimethylspiroundecanone is known for its low volatility, which helps maintain consistent fragrance performance throughout product use. It also displays good biodegradability, addressing environmental concerns associated with some synthetic musks. Typically used at concentrations between 0.1% to 1% in leave-on products and up to 0.5% in rinse-off formulations, it complies with international fragrance safety standards when used within recommended limits.
