Arctander writes very extensively about vanillin and some extracts are presented here: “among the more common perfume materials, vanillin is one of the most tenacious odors known.”; “its intense sweetness is utilized in industrial masking odors and in high-cost luxury perfumes, and it can be used in almost any type of fragrance, from woody or herbaceous to oriental or floral.” he also points out that because vanillin is such a high volume product it is chemically one of the purest materials used in perfumery. this together with improvements in base products mean that the use of low doses of vanillin in fragrances for functional products such as white soaps and creams is no-longer the hazard it once was, though discolouration can still occur where higher amounts are involved.
