The present lipid-based wax compositions commonly include a polyol fatty acid ester component (made up of partial and/or completely esterified polyols). Generally, at least a portion of the polyol fatty acid ester has been subjected to a transesterification reaction. Lipid-based wax compositions having a melting point of about 48~C to about 75~C can be particularly advantageous for use in forming candles. The wax may contain other components such as mineral wax, plant wax, insect wax, and/or other components. The polyol fatty acid ester component can include triacylglycerols such as those derived from plant oils (soybean oil, palm oil, etc.). The polyol ester component may be characterized based on one or more of its physical characteristics, such as SFI-40, SFI-10, typical crystal structure, IV, melting curve, and/or other properties.

L'invention concerne des compositions de cire à base lipidique qui comportent généralement un composant d'ester d'acide gras polyol (à base de polyols partiellement et/ou entièrement estérifiés). D'ordinaire, au moins une partie de l'ester d'acide gras polyol est soumis à une réaction de transestérification. Les compositions de cire à base lipidique ayant un point de fusion situé entre environ 48 ·C et environ 75 ·C peuvent être particulièrement intéressantes pour former des bougies. La cire peut contenir d'autres composants, par exemple une cire minérale, une cire végétale, une cire d'insecte et/ou d'autres composants. Le composant d'ester d'acide gras polyol peut comporter des triacylglycérols tels que ceux dérivés d'huiles végétales (huile de soja, huile de palme, etc.). Le composant d'ester polyol peut être caractérisé sur la base d'une ou de plusieurs caractéristiques physiques telles que SFI-40, SFI-10, structure crystalline type, IV, courbe de fusion, et/ou d'autres propriétés.
