I am curious if anyone uses desiccant packets (silica gel) in boxed soaps packaging or storage. I have seen a few people here talk about storing soaps in paperboard shoe boxes with holes for aeration.
But since some soap seems to sweat a lot more than others, I've been considering buying some. In searching the right size to use, I found that a 10 gram packet is recommended for a 5 gallon bucket with an air-tight lid (approximately 1158 Cubic Inches in volume) so that gives me an idea of the size of packets to use for smaller areas. So about 1 gram per 115.8 CU IN. I'd have to do some box measurements, of course, for each calculation if I ever decide to go this route, but it's something I've been wondering about.
But the other concern I have is this: Do all silica desiccant packets also absorb odors? If that is the case, then I suppose they wouldn't be good for scented soaps. I can't seem to find a definitive answer to the odor absorption question.
