APS or SPS?
Both are highly soluble and radical-forming in water. Choose sodium persulfate when you need to keep ammonium out of the process. Polymerizing a gel? We also supply the MBA cross-linker.
Storage and handling
Both are class 5.1 oxidizers. They do not burn, but they do promote fire and can decompose under poor conditions. Keep bags sealed, cool and dry, and away from reducing agents and organic material. Dust can irritate and sensitize skin and airways, so read the safety data sheet before use.
