I have been shrink-wrapping more soap and this lead me to review the recipes for said soap for when I label them. That lead me to wonder why some of my soaps are sweating more than others, which lead me to wondering if I should just go back to recipes from 2 years ago that never sweat, which lead me to reviewing many of my recorded soaping formulas in my notebooks. Then of course, I began to wonder why the exact same recipe used in July 2017 does not sweat, but when made in January, 2018 DOES sweat right now.
My husband thinks it has to do with the added moisture to the air when the soap was made in winter when we heat the house but also add moisture to compensate for the drying nature of heated air in the winter, whereas in the summer the AC is turned on and the de-humidifier pulls moisture from the air. To me this is all very confusing. My formula for 2 soaps is exactly the same down to dual lye and lye concentration, except in one case I used sugar as an additive, but that one does not sweat. It was made in July 2017. But in all cases where the soap was made in January 2018 and without sugar, that soap is sweating right now. But the soap made in July 2017 does not sweat. I am confused and can't come up with enough differences between the soaps to theorize the reasons for sweating vs non-sweating. Other than fragrance differences and time of year when the soap was made, and possibly different colorants (although all were micas from Micas & More), nothing else springs to mind.
I have had a headache for two days, so this just might not be the right time to try and figure this out, though. So I really should stop trying to concentrate on this topic for now, and maybe come back to it after my mind is more clear for thinking.
