I have read pages and pages of useful information, but will feel better about trying Golden Wax 415 after I have feedback on what I think I learned by reading the various threads. For the uninitiated, Golden Wax 415 = partially hydrogenated soybean oil. According to the SoapMakingFriend calculator, the NaOH SAP is .136 for soybean oil and 27% hydrogenated soybean oil, and .137 for 100% hydrogenated soybean oil. As others seem to have indicated in previous threads, it doesn’t really matter which version of soybean oil I pick from the oil list because the SAP varies so little. But, how do we get the correct fatty acid profile in the calculator? I’m a bit worried about the high percentage of linoleic oil in the unhydrogenated fraction of soybean oil. ETA: If you don’t want to read all of the details of how I got there, you can find my current best estimate of the fatty acid profile for Golden Wax 415 in post #8. Golden Wax 415 is partially hydrogenated, but exactly how partially hydrogenated seems a bit up in the air. According to the calculator and the threads, the degree of hydrogenation affects the FA profile as follows - the more hydrogenated, the less linoleic oil. In one of the threads, a contributor mentioned the manufacturer’s spec sheet, which I never found linked, and also linked this paper. Specifically, Table 1 provides the FA profiles of partially hydrogenated soybean oil based on iodine value (IV). The IV for Golden Wax 415 averages around 50, based on the Certificates of Analysis posted on the Candle Science website, here. If the relationship between IV and FA composition is a general one, and the IV is the same as the “iodine” in a soap calculator, then maybe the FA profile of GW 415 can be determined based on the IV (fingers crossed)... Like this: Edited on October 12, 2019 to remove an approximation of the composition of GW 415 that could be misleading for newbies (like me!). It remains available as an attachment. ETA: But, looking at it again, I see that the resulting FA percentages don’t match the ones in the table in the paper. (Time to quit for the night!) If someone has the manufacturer’s spec sheet and would be willing to share it or knows where it is linked and can send me there, please do. TIA!
