One of the fragrance ingredient groups that many people with a bit of knowledge of fragrance have at least heard of is the Aldehydes. Made famous by their inclusion in Chanel 5 they have been in widespread use in perfumes since the 1920s.<\/span><\/p>\n

\nWhen we talk about aldehydes in the context of perfumery what is usually meant is the group of odorous chemicals more accurately called saturated<\/a> aliphatic<\/a> aldehydes<\/a><\/i><\/b>.  There are in fact quite a lot of other<\/i> aldehydes routinely used in perfumery including such commonplace materials as vanillin<\/a> (the key component in vanilla) but in this post I’m focussing on that particular group with the characteristic aroma, described by perfume people as ‘aldehydic<\/i>‘.<\/span><\/div>\n

\nBesides being olfactorily interesting these materials also have some special characteristics from the perspective of storage and use.  All are very powerful and hence tend to be used in very low doses but they can have a very high impact on the scent.  Several are found in nature, notably in citrus oils where they contribute to the bright, sparkling, fresh nature of those materials.<\/span><\/div>\n
