Description

  The present disclosure relates to mosquito coils.

  Mosquito coils are accompanied by a unique irritating odor when smoked. The peculiar irritating odor is caused by a burning odor generated by the combustion of a flame retardant such as wood powder. Such pungent odors are generally attempted to be improved by using fragrances. As a fragrance | flavor, the heat diffusion fragrance | flavor (patent document 1) which has a comparatively high boiling point, sandalwood, mandala, etc. are used, for example. However, in the conventional method, improvement of the irritating odor is insufficient, the irritating odor is suppressed, and a mosquito coil with a pleasant scent is desired.
