TRIMETHYL-7-OXABICYCLOHEPTYL)-3-BUTEN-2-ONE

Description

TRIMETHYL-7-OXABICYCLOHEPTYL)-3-BUTEN-2-ONE, commonly known as Karanal, is a synthetic fragrance ingredient used in various skincare and personal care products. This compound belongs to the class of polycyclic musks, prized for their long-lasting and complex scent profiles. Karanal exhibits a woody, amber-like aroma with subtle floral undertones, making it a versatile choice for perfumers and formulators.

In skincare formulations, Karanal serves primarily as a fragrance enhancer, helping to mask unpleasant odors from active ingredients while providing a pleasant sensory experience for users. Its molecular structure allows for slow evaporation, contributing to the longevity of the scent in products. Karanal has demonstrated good stability in various cosmetic bases and is compatible with a wide range of other ingredients.

While primarily used for its olfactory properties, Karanal may also contribute to the overall preservation of formulations due to its antimicrobial properties. However, as with many fragrance ingredients, it should be used judiciously in skincare products, particularly those intended for sensitive skin. Dermatologists recommend patch testing products containing this ingredient to ensure individual tolerance.
