Yes, there are that many flavors containing diacetyland there are just as many that contain acetyl proprionyl & acetoin (other "butter" flavors), especially since diacetyl has been limited or removed from many 'vaping flavors'. Diacetyl (IUPAC systematic name: butanedione or butane-2,3-dione) is an organic compound with the chemical formula (CH3CO)2. In this disease, the smallest airways in the lung (the bronchioles) become scarred and constricted, blocking the movement of air.

Low levels are present in butter (including unsalted butter, to which extra diacetyl is added to prolong its shelf life). Diacetyl is a naturally occurring ingredient that provides a creamy, buttery taste. Cooking or popping of products containing diacetyl and other butter flavoring chemicals should be done in a food preparation area with adequate exhaust ventilation. Some additives are considered safe or possibly beneficial. In the case of workers at microwave popcorn facilities across the Midwest, NIOSH studies found that mixers who worked with diacetyl and heated soybean oil for more than a year were exposed to higher levels of diacetyl fumes and experienced more shortness of breath than workers employed for less than 12 months or who worked elsewhere in the plant..
