Galaxolide is the trade name from International Flavors & Fragrances Inc. (IFF) for the fragrance material with CAS Registry Number1222-05-5 and CAS chemical name cyclopenta(g)-2-benzopyran, 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethyl-. Galaxolide is also known by its IUPAC name 4,6,6,7,8,8-hexamethyl-1,3,4,6,7,8-hexahydro-cyclopenta[g]-isochromen...
Galaxolide is a mixture of isomers. It has chiral centers at carbon atom 4 and 7. The isomers are (4R,7R), (4R,7S), (4S,7S) and (4S, 7R). Galaxolide has a molecular formula of C18H26O and a molecular weight of 258.4 g/mol. At room temperature, it occurs as a highly viscous liquid. Its melting point is -20 °C and its boiling point is estimated to be...
Galaxolide was discovered at IFF in the 1960s, by Heering and Beets. It was first synthesized in 1965 and its discovery was mainly due to the work by Beets on the osmophoric group of the polycyclic musks, where they tried to improve existing synthetic musks by making them more stable and hydrophobic
Galaxolide has become the key synthetic musk ingredient belonging to the polycyclic musk group as defined by the International Fragrance Association (IFRA). Its odor is described as a “clean”, sweet, floral, woody musk, Research has shown that it is in particular the (4S,7R) and the (4S, 7S) forms of galaxolide that are the most powerful musk notes...
Galaxolide has a measured bioconcentration factor (BCF) in fish in a range of 600-1600 and a log octanol-water partition coefficient (Log Kow) of around 5.5 (5.3 – 5.9). Given its lack of bioaccumulation and toxicity, the EU determined that galaxolide does not meet the criteria for being a substance classified as Persistent, Bioaccumulative and Tox...
Galaxolide is not an irritant, not toxic, not a CMR substance nor a sensitizer.Based on test data, the EU Scientific Committee for Consumer Safety included galaxolide in their proposal for extending the allergen information on cosmetic products as it claims to have seen only up to 100 individual cases worldwide in the last several decades who have ...
In 2002, The Scientific Committee on Cosmetics and Non-Food Products (SCCNFP), the expert scientific board that advises the European Commission on human health issues, reviewed the human safety of galaxolide, when used in cosmetic products, and issued a final opinion on 17 September 2002.The SCCNFP stated that "...HHCB [galaxolide] can be safely us...
