SAP may absorb 500 times its weight (from 30-60 times its own volume) and can become up to 99.9% liquid, but when put into a 0.9% saline solution, the absorbency drops to maybe 50 times its weight.
The largest use of SAP is found in personal disposable hygiene products, such as baby diapers, adult protective underwear and sanitary napkins. SAP is also used for blocking water penetration in underground power or communications cable, horticultural water retention agents, control of spill and waste aqueous fluid, artificial snow for motion picture and stage production. The first commercial use was in 1978 for use in feminine napkins in Japan and disposable bed liners for nursing home patients in the USA.

The price per quantity supplied is about the best, if you don't need a whole pound or more.
Remember that a little goes a very long way.
I found that if mixed into your potting soil bag, all the work is done.
