Abstract
A hybrid wax compositions that are suitable for use in manufacturing wax articles (e.g., candles) by compression molding. The combination of a hydrogenated natural oil-based wax and a paraffin wax having a select distribution of hydrocarbon chain lengths provides the hybrid wax compositions with improved properties, such as improved compressive strength and improved de-molding characteristics, for example, as evidenced by reducing scarring and/or flashing. The hybrid wax compositions comprise: (a) a wax comprising a hydrogenated natural oil; and (b) a paraffin wax, wherein the paraffin wax comprises less than about 50% by weight of the hybrid wax composition, and wherein about 52% or greater of hydrocarbons in the paraffin wax have carbon chain lengths ranging from C25 to C29.
