Description and usage notes:
Very intense, classic aliphatic aldehyde valued for its floral and citrus enhancement as well for imparting the recognisable aldehydic quality to a fragrance. Much used in laundry and soap fragrances as well as in fine fragrance.
Arctander describes the odour like this: “Sweet, waxy-herbaceous, very fresh and clean-floral odor (Lily-Violet-like in dilution) with a faint, balsamic undertone. The odor is often referred to as ‘fresh-laundry-odor’, but it is only pleasant in extreme dilutions. The concentrated material has a rather fatty-waxy odor.”
He goes on to say: “It is one of the most extensively used alifatic aldehydes in perfumery. Its versatility is probably its greatest asset: from Pine to Violet, from detergent perfumes to luxury lotion fragrances it finds its way into a multitude of fragrance types: Pine, Pine needle, floral, “modern”, Citrus complexes, Chypres, etc.”
This is one of those superpower ingredients that is used in traces. If you normally work with ingredients diluted to 10%, we recommend using this at 1% or even 0.1% – it’s very easy to overdose. It is supplied here at 10% in ethanol because this is one of the least stable of the aliphatic aldehydes with a strong tendency to polymerise on lengthy storage. If ethanol would be unsuitable for the application you have in mind for the aldehyde, we also offer it at 10% in Benzyl Alcohol, which is much more suitable for use in soaps, wax and so on, but still provides the stabilising effect needed to keep the aldehyde in good condition.
Bedoukian writes that “Lauric aldehyde has an extremely powerful fatty note, noticeable even in high dilutions. Because of its higher molecular weight it is long lasting, a property which adds to its value. In general it is use in conjunction with undecylenic, and to a lesser degree, with decyl aldehyde.”
