6-ETHYLIDENEOCTAHYDRO-5,8-METHANO-2H-1-BENZOPYRAN-2-ONE

Description

6-Ethylideneoctahydro-5,8-methano-2H-1-benzopyran-2-one, also known as Tonalide, is a synthetic musk compound widely used in the fragrance industry and personal care products, including skincare formulations. This ingredient belongs to the polycyclic musk family and is prized for its long-lasting, warm, and woody scent profile. In skincare applications, Tonalide serves as a fixative, helping to stabilize and prolong the fragrance of products. Its molecular structure allows it to bind well with other ingredients, enhancing the overall scent experience of skincare formulations.

While primarily utilized for its olfactory properties, Tonalide may also contribute to the texture and feel of skincare products. Its low water solubility and high lipophilicity enable it to blend seamlessly with oils and emollients, potentially enhancing the smooth application of creams and lotions. However, it's important to note that Tonalide has faced scrutiny due to environmental concerns, particularly its potential to bioaccumulate in aquatic ecosystems. As a result, some formulators are exploring alternative fragrance options. When used in skincare, Tonalide is typically present in small concentrations, usually less than 1% of the total formulation.
