Seeking the sweet smell of successBy our Editorial Team - 15th January 2018
Although there is no universal definition of what constitutes a HIAC, it is generally agreed that the material must have a low odour threshold (usually a minimum of around 10 ppb) and a recognisable character even at low concentrations. HIACs are used as key ‘top-note’ ingredients in flavour and fragrance applications.
“Most of our team have their own favourites, but a few examples are 3-(methylthio)butanal (which has strong French fries/chips characteristics), 2-propionylthiazole (strong rice notes) and the more well-known para-mentha-8-thiol-3-one (a strong blackcurrant odour),” he says.
Essence of innovation
Endeavour has two R&D laboratories that ensure the company’s processes are continually evolving to make use of new thinking.
Alongside its range of aroma chemicals, building blocks and reactive intermediates, Endeavour offers custom synthesis services.
“We are always looking to partner with customers on projects they wish to outsource, or for which we can provide a custom synthetic route,” declares Dr House. “The end product may be a feasibility report, a prepared sample or a larger target quantity. The chemistries are rigorously dissected by our R&D team and, with a combination of experience, innovative thinking and practical knowledge, we are usually able to give our customers what they require. Such is the nature of R&D work that, as excellent as the team is, we are not always successful. However, we will always provide options for our customers to work with.”
Treatt has been Endeavour’s exclusive global distributor of HIAC for more than 20 years and, in September 2017, Endeavour signed a new long-term distribution agreement with Treatt, ensuring continued global distribution of the company’s UK-manufactured HIAC to the flavour and fragrance sectors.
