To comply with the California Health and Safety Code - HSC § 11107.2, we have introduced a naturally occurring plant-based odorant known as grapefruit mercaptan or p-Menthene-8-thiol with a chemical purity of 99%. Mercaptans, also known as thiols, are organic compounds containing a sulfur atom bonded to a hydrogen atom (-SH group) in their chemical structure. Both grapefruit mercaptan and ethyl mercaptan (also known as ethanethiol) possess an extraordinarily low smell perception threshold, defined as the lowest concentration of a substance in the air detectable by the human sense of smell. Even a minute quantity can be readily detected. EGI adheres to th
