  • Publication number: 20220195333
    Abstract: Proposed is a natural wax composition including 80 to 95 parts by weight of natural plant oil being a mixture of different kinds of oil, 3 to 20 parts by weight of wax, and 1 to 3 parts by weight of a preservative. Therefore, a natural wax composition can be provided that enables anyone to easily and conveniently mold Do-it-Yourself (DIY) scented candles even without the need for any expert knowledge for making scented candles. The natural wax composition can exhibit cream-type properties, leading to a reduction in liquefaction time compared to solid wax, thereby significantly reducing the manufacturing time of scented candles.
