Ahn, Jeong-Hyeon;Kim, Ki-Hyun;Kim, Yong-Hyun;Kim, Bo-Won published 《Characterization of hazardous and odorous volatiles emitted from scented candles before lighting and when lit》. The research results were published in《Journal of Hazardous Materials》 in 2015.Application of 78-69-3 The article conveys some information:
Scented candles are known to release volatile organic compounds (VOC) with pleasant aromas and toxic components before lighting (off) and when lit (on). This work examined compositional changes of scented candle VOC under various settings simulating indoor use. Carbonyl compounds and other VOC emitted from 6 different candle types were analyzed for on/off conditions. The 6 candle types were: clean cotton (CT); floral (FL); kiwi melon (KW); strawberry (SB); vanilla (VN); and plain (PL). Although a large number of chems. were released before lighting and when lit, their profiles were noticeably distinguishable. Before lighting, various esters (n = 30) demonstrated the most dominant emissions. When lit, formaldehyde had the highest emission concentration (2098 ppb [SB], 1022 ppb [CT], 925 ppb [PL]). For most lit scented candles, there was a general tendency for increased concentrations of low b.p. compounds For some scented candle products, VOC emissions occurred strongly before lighting and when lit. For example, in terms of total VOC (ppbC), highest concentrations were observed with KW candles: 12,742 ppbC (on) and 2766 ppbC (off). Hence, results suggested certain scented candles should act as potent VOC emission sources in indoor environments, regardless of conditions, i.e., un-lit or lit.3,7-Dimethyloctan-3-ol (cas: 78-69-3) were involved in the experimental procedure.
3,7-Dimethyloctan-3-ol(cas:78-69-3) is a fatty alcohol that is 3-octanol substituted by methyl groups at positions 3 and 7.Application of 78-69-3 Metabolite observed in cancer metabolism. It has a role as a human metabolite.
