What is Butyl salicylate?
Chemical properties
Butyl salicylate has a rough, herbaceous, chemical odor with a trace of wintergreen.
Occurrence
Reported found in mountain papaya.
The Uses of Butyl salicylate
Butyl salicylate is used in perfume compositions as a modifier for higher esters of Salicylic acid. It produces a Fougere-like note with Coumarin and Lavandin - with or without Oakmoss - but not as attractive as the one obtainable with the Amylester. Blends well with the herbaceous oils, with Pine needle oils and related chemicals (Bornyl family), with Cedarwood producls and it gives good fixative effect along with the simple Nitromusks in low-cost perfumes.
Preparation
By direct esterification of n-butanol with salicylic acid under azeotropic conditions.
Definition
ChEBI: Butyl salicylate is a member of phenols and a benzoate ester. It is functionally related to a salicylic acid.
Aroma threshold values
Detection 5 to 7 ppb; Recognition 10 ppb
