>>Is that polymer approved for human consumption?
While the product is not considered toxic/hazardous based on laboratory animal tests it is NOT intended or meant for human consumption at all. Or for reptiles, mammals, birds, etc. The polymer swells up A LOT when it comes in contact with water. Can you imagine how much room just a couple of crystals can ultimately take up in a stomach when those crystals can swell up to 3 inches in size? The polymer should only be given to feeder insects and only when full hydration capacity has been reached.
I've been doing an absorption experiments with some crystals. I took 5 grams of dry crystals (equal to the weight of a nickel). I filled a large bowl with water and added the crystals.
After 4 hours, I drained the excess water off and weighed the crystal gel. The crystals had absorbed enough water to weigh in at 693 grams. I refilled the bowl with water and at the 18 hour mark the gel had continued to absorb water and weighed in at 976 grams. After 24 hours (i.e. today at 4:30pm) I was still seeing some tiny bit of absorption going on. The gel now weighed in 978 grams. Now imgagine seeing that little 5 gram sample now weighing in at over 2 lbs. Talk about super absorbancy. dunno if my math is right but that is like a 19,500% increase.
I am going to let the gel continue to hydrate for another 6 hours to see if it is capable of taking in anything more though I think I finally hit the plateu.
The original use for the crystals was as a soil additive to help maintain moisture levels in the soil so that one did not need to water as frequently and the swelling/shrinkage action of the crystals also helped to aerate soils.
