Our wax melts are made from an all natural soy tart wax specifically formulated for wax burners and melters (including Scentsy melters). Our melts contain an 18% fragrance load, which gives our melts an extra 33% boost in performance and life, in comparison to other waxes used for producing waxt melts. Formulated from a blend of veggie and soy wax, our melts contain no additives or dyes...making them the cleanest wax melt on the market. All our fragrances are phthalate free and are safe to use in any domain.
