The World of Wax: Wax Crystal Morphology:
Crystal Morphology
In liquid oils (solvents), the critical gelling concentrations of waxes are attributed to the polarity of the solvents, and to the nature of wax-wax and wax-solvent interactions. The gelling behavior of natural waxes in liquid oil is governed by the wax crystal morphology, which are determined by the nature and chain length of the chemical components present in waxes. In addition, the gelling behavior of wax-based oleogels can be tuned by altering the cooling and shear rates, and by changing the time and temperature of cooling. Even within one type of wax, the chemical composition can vary greatly depending on the growing conditions, the maturity stage and the geographic origin of the plant/animal from which the waxes are extracted.
In natural waxes, the chemical composition, polarity, chain length, and melting point of the dominant components determine the crystal morphology and crystalline structure of waxes.
Anhydrous systems usually consist of several waxes combined with emollients and other functional ingredients. Complex structures get formed very dependent on the properties of the single components. Even small changes in production procedure can significantly impact the characteristics of the oleogel. Unfavorable combinations or unsuitable production conditions can cause instabilities that are often irreversible.
This presentations gives an overview of the crystal morphologies of commonly used natural waxes and insights how to improve the stability of oleogels.
