    Study Notes

    Chemical Process Industry

    • Solvents are used not to irritate the human skin, and the slight natural odor of the alcohol is removed by deodorizing or "pre-fixation" of the alcohol
    • This is accomplished by adding a small amount of gum benzoin or other resins to the alcohol and allowing it to mature for a week or two.
    • The result is an almost odorless alcohol
    • In an ordinary solution of perfume substances in alcohol, the more volatile materials evaporate first, and the odor of the perfume consists of a series of impressions rather than the desired ensemble.
    • To obviate this difficulty, a fixative is added.
    • Fixatives may be defined as substances which retard and even up the rate of evaporation of the various odoriferous constituents.
    • Types of fixatives include animal fixatives, essential oils, and synthetic chemicals.
    • Fixatives are not necessarily contributing to the main fragrance of the finished product, if they do contribute, they must blend with the other constituents.

    Animal Fixatives

    • Of all animal products, castor or castoreum (a brownish orange exudate from the perineal glands of the beaver is employed in the greatest quantity).
    • Benzyl alcohol, acetophenone, l-borнеоl, and castorin (a volatile resinous component of unknown structure)
    • Civet, found in countries like Ethiopia, is a soft, fatty secretion of the perineal glands of civet cats.
    • The crude civet is disagreeable in odor, but on dilution and aging, the skatole odor disappears, and a sweet and somewhat floral odor of civetone, a cyclic ketone, appears.

    Musk

    • Musk is the dried secretion of the prepucial glands of the male musk deer, containing a cyclic ketone muskone.
    • Musk is useful, even when diluted, in perfumes due to its own odor.
    • Ambergris, the least used of the animal fixatives, is a secretion from certain whales.
    • It is composed of 80 to 85% ambrein, (triterpenic tricylic alcohol), resembling cholesterol.
    • The odor of the tincture is decidedly musty and has great fixative powers.
    • Musk zibata is a new animal fixative derived from the Louisiana muskrat.
