The present invention relates to the technical field of scented booster beads, and more particularly to heat-resistant scented booster beads and a method for producing the same. [Solution] The scented booster beads have a melting temperature of >50°C, and the scented booster beads are packaged using a modified starch with a weight-average molecular weight of 5,000-20,000. The heat-resistant scented booster beads of the present invention can have an improved melting temperature by using a modified starch with a high melting temperature as the packaging material. This ensures that the scented booster beads can withstand high temperatures during shipping and prevents the scented booster beads from becoming ineffective. Furthermore, the use of a modified starch with a predetermined weight-average molecular weight increases the melting temperature and shortens the setting time. Therefore, when producing scented booster bead particles using a screw extruder, the particles can be quickly molded. Furthermore, by thoroughly encasing the essence, the scented booster beads can release their aroma for a long period of time and reduce aroma loss.

Maintaining or enhancing the solubility and stability of natural products in personal products is a desirable characteristic that can be attained by using natural eutectic solvents (NADES).
