Ethyl mercaptan is a flavoring agent added to propane-butane and natural gas to give them a distinctive smell. The process and exact amount of flavoring added are strictly monitored.  <\/p>\n<p>The addition of ethyl mercaptan to LPG is also the reason why propane-butane cylinders smell stronger when they are almost empty. The flavoring agent is less volatile than the propane in which it is dissolved. This is why, as the cylinder empties, the smell of ethyl mercaptan becomes stronger.  <\/p>\n<p>Most people describe the smell of ethyl mercaptan as garlic, rotten eggs, or cabbage. Others cannot smell it and rely on electronic sensors to detect gas leaks. <\/p>\n<p>An interesting fact is that flies like the smell of ethyl mercaptan. So if you notice them circling around LPG bottles or appliances that use it, make sure there are no gas leaks and that the cylinders are closed. <\/p>\n<p><em>You can find out more <\/em><a href=\"https:\/\/v-gas.bg\/en\/the-history-of-propane-butane\/\"><em>interesting facts about LPG<\/em><\/a><em> by regularly following our blog and <a href=\"https:\/\/www.facebook.com\/VGasBG\/\" target=\"_blank\" rel=\"noopener\"><em>the Facebook page of Vi-Gaz Bulgaria EAD<\/em><\/a><em>.<\/em><\/em><\/p>\n<p><a href=\"https:\/\/v-gas.bg\/wp-content\/uploads\/2019\/09\/lpg-smell.png\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-1915 aligncenter\" src=\"https:\/\/v-gas.bg\/wp-content\/uploads\/2019\/09\/lpg-smell.png\" alt=\"\" width=\"640\" height=\"400\"><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Did you know that propane-butane is odorless, but an odorizer\u2014ethyl mercaptan\u2014is added to it so that any leaks can be easily detected?
