beta-Napthyl methyl ether Crystals Description and usage notes: A powerful traditional perfumery material with a sweet floral aroma of orange blossom, acacia and neroli. Widely used in classic fragrances.   This is a highly refined >99% pure grade, made especially for use in perfumery. It comes as pearlescent powdery crystals, that are rather beautiful but take quite a lot of agitation to dissolve successfully so for those who don’t have access to an automatic stirrer or shaker we also offer it at 20% in DEP through this product. The diffusion and persistence of this product is really remarkable and it performs exceptionally well in air-care applications. Arctander gives us some useful data: “The odor of highly purified material is intensely sweet, Orangeblossom-Acacia-like, very tenacious, but many commercial grades are poorly refined and display rather harsh notes, an odor description generally used for this material... This ether is used extensively in low-cost fragrances for household products, soaps, detergents (but rarely in dishwashing detergents), and particularly in products where heat-and-alkali-stability are required. It is also used as masking odor for acrylic or other 'plastic' odors, synthetic rubbers, etc., which requires good retentiveness. A very inexpensive, non-purified grade is available for industrial masking purposes, and it offers powerful odor and good fixation. There is a considerable difference in price between the crude and the refined grades. [the crude] product is brownish, dark amber-colored or pale purple colored, usually in lumps of crystalline structure... [quite different from] the white refined product.”
