Alicyclic Musk - in 1975, Ciclomusk was presented, an alkyl from the very simple structure and very different from all known structures of synthetic Musks. It was followed by Helvetolide of Firmenich in 1990 and then Romanolide
This class of synthetic Musks seems to have solved almost all possible toxicity problems, real or alleged, attributed to other musks.
and contact sensitization of nitro musk perfume raw materials.
Synthetic musks have been used, for far more acceptable costs, to spice up a myriad of products: detergents, Toiletry products, perfumes and body lotions, insecticides and foods such as chocolate, liquorice, sweets, chewing gums. Even the fruit flavours and vanilla used in the kitchen contain some (5). Between 1995 and 2000, from 200 to 300 tonnes of Musk Ketone and Musk Xylene were produced and only in the year 2000, at least 4.000 tonnes of polycyclic musks have been consumed (6). The European market for synthetic musks has accounted for 95% for four substances, Musk Ketone, Musk Xylene, Tonalide and Galaxolide (7) which is the "clean smell" of almost all detergents, softeners and environment deodorants and even toothpastes. Because of their widespread use in detergents and products such as shampoo and bath foam, they end up in water and since they are not easily metabolised, they are reintroduced into the food chain. Accumulations have been found in animal and human tissues. Actually, there is still no certain data on their direct toxicity, but they are under careful investigation and research is today oriented in finding alternative substances that are more easily biodegradable. Of course one cannot imagine a perfumery without Musk!
Perfumes have been known to exist in some of the earliest human civilizations, either through ancient texts or from archaeological digs. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as or , which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics alone.

Drawing on his experience as Halston's international fragrance director, he published a guide that took the hassle out of selecting a new fragrance. What started as a simple yet innovative reference for staff in perfumeries and department stores has evolved into the world's most comprehensive fragrance manual. Fragrances of the World 2001 classifies more than 2,600 female and male fragrances.
Synthetic musk : definition of Synthetic musk and …
In contrast to ketones, aldehydes can easily be oxidized into acids; that means they also have reducing characteristics. Formaldehyde changes to formic acid and acetaldehyde to acetic acid. With unprotected open storage especially the aromatic aldehydes may chemically change into the respective substituted benzoic acids. Accordingly, essential oils and perfumes that are rich in aldehydes may change their scent with extended storage.
The conversion products of 2 alcohol molecules with an aldehyde or ketone molecule have a particularly agreeable scent. Acetals and ketals are formed in this process while the water escapes. The substances also occur in natural surroundings and may easily be synthetically manufactured. They are frequent components of perfume compositions.
In cases where the remaining alcohol group of an aldose (carbonyl group at the end of a monosaccharide) or of a ketose reacts with an alcoholic HO-group, specific acetals or ketals will form which belong to the group of glycosides. This substance class is widely spread in natural surroundings (as e.g. in saccharose or lactose). After contact with acids, acetals, ketals and glycosides will decompose into their basic components. This is why they are also called disguised aldehydes and ketones. And by the way: vitamin C also is a disguised ketone.
