Carnauba Wax - Composition

Composition

Carnauba consists mostly of aliphatic esters (40 wt%), diesters of 4-hydroxycinnamic acid (21.0 wt%), ω-hydroxycarboxylic acids (13.0 wt%), and fatty acid alcohols (12 wt%). The compounds are predominantly derived from acids and alcohols in the C26-C30 range. Distinctive for carnauba wax is the high content of diesters as well as methoxycinnamic acid.

Carnauba wax is sold in several grades, labeled T1, T2, and T4, depending on the purity level. Purification is accomplished by filtration, centrifugation, and bleaching.

Famous quotes containing the word composition:

    Those Dutchmen had hardly any imagination or fantasy, but their good taste and their scientific knowledge of composition were enormous.
    Vincent Van Gogh (1853–1890)

    Viewed freely, the English language is the accretion and growth of every dialect, race, and range of time, and is both the free and compacted composition of all.
    Walt Whitman (1819–1892)

    If I don’t write to empty my mind, I go mad. As to that regular, uninterrupted love of writing ... I do not understand it. I feel it as a torture, which I must get rid of, but never as a pleasure. On the contrary, I think composition a great pain.
    George Gordon Noel Byron (1788–1824)
