TETRAMETHYL-3-CYCLOPENTENEBUTANOL

Description

Tetramethyl-3-cyclopentenebutanol, also known by its trade name Karmentin, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This colorless to pale yellow liquid possesses a distinctive woody, amber-like scent with subtle floral undertones. Its molecular structure consists of a cyclopentene ring with four methyl groups and a butanol side chain.

In skincare formulations, tetramethyl-3-cyclopentenebutanol serves primarily as a fragrance component, enhancing the overall sensory experience of products. It is particularly valued for its ability to impart a warm, sophisticated aroma that can mask less pleasant odors associated with active ingredients. This compound exhibits good stability across a range of pH levels and temperatures, making it suitable for various product types.

While its primary function is olfactory, some studies suggest that tetramethyl-3-cyclopentenebutanol may have mild antimicrobial properties, potentially contributing to product preservation. However, its use in formulations is typically limited to concentrations below 1% to comply with safety regulations and minimize the risk of skin sensitization. As with any fragrance ingredient, patch testing is recommended for individuals with sensitive skin or known fragrance allergies.
