Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. While sodium neutralized polyacrylic acids are the most common form used in industry, there are also other salts available including potassium, lithium and ammonium. The origins of superabsorbent polymer chemistry trace back to the early 1960s when the U.S. Department of Agriculture developed the first super absorbent polymer materials.[2] ApplicationsSodium polyacrylate and other derivatives of polyacrylic acid have a wide variety of commercial and industrial uses. These include: {{div col}}
Safety for humansAcrylic acidAs a leftover of producing sodium polyacrylate, acrylic acid would cause a rash when contacts with skin. It should be less than 300 PPM as the absorbent material in paper diaper.[14] References1. ^{{Cite web|url=https://www.supplieer.com/water-absorbing-material-sodium-polyacrylate-uses-list/|title=Water absorbing material – Sodium polyacrylate|last=|first=|date=|website=|archive-url=|archive-date=|dead-url=|access-date=}} 2. ^1 {{cite web | url = http://www.m2polymer.com/html/history_of_superabsorbents.html | title = History of Super Absorbent Polymer Chemistry | publisher = M2 Polymer Technologies, Inc. | accessdate = 29 April 2009}} 3. ^1 2 {{Cite web|url=https://www.howtor.com/superabsorbent_polymer_sap.html|title=Superabsorbent polymer (SAP)|last=|first=|date=|website=Howtor|archive-url=|archive-date=|dead-url=|access-date=}} 4. ^{{Cite web|url=https://www.howtor.com/easy-get-rid-horse-manure-urine-smell-sodium-polyacrylate.html|title=Easy to Get Rid of Horse Manure / Urine Smell|last=|first=|date=|website=|language=en-US|archive-url=|archive-date=|dead-url=|access-date=2018-02-02}} 5. ^1 2 3 4 5 6 7 8 9 10 11 12 13 {{Cite web|url=https://www.howtor.com/super-absorbent-polymer-uses.html|title=Sodium polyacrylate uses|last=|first=|date=|website=Howtor|archive-url=|archive-date=|dead-url=|access-date=}} 6. ^{{cite web|url=https://householdproducts.nlm.nih.gov/cgi-bin/household/brands?tbl=chem&id=2897|title=Chemical Name: Sodium Polyacrylate|date=August 2015|work=Household Products Database|publisher=U.S. Department of Health and Human Services|accessdate=August 29, 2016}} 7. ^{{cite web|url=https://web.archive.org/web/20160403034750/http://disposablediaper.net/faq/what-are-the-components-of-a-typical-disposable-diaper/|title=What are the components of a typical disposable diaper?|access-date=January 8, 2015}} 8. ^{{Cite web|url=https://www.howtor.com/diaper-polymer-sodium-polyacrylate-superabsorbent-polymer-sap.html|title=Sodium polyacrylate for diapers|last=|first=|date=|website=|archive-url=|archive-date=|dead-url=|access-date=}} 9. ^{{Cite web|url=https://www.howtor.com/industrial-waste-liquid-management-sodium-polyacrylate.html|title=Best way for industrial waste liquid management: Sodium Polyacrylate|last=|first=|date=|website=|archive-url=|archive-date=|dead-url=|access-date=}} 10. ^{{Cite web|url=https://www.howtor.com/sodium-polyacrylate-absorbent-material-inflatable-sandbags.html|title=Sodium polyacrylate – the absorbent material of Inflatable sandbags|last=|first=|date=|website=|archive-url=|archive-date=|dead-url=|access-date=}} 11. ^{{Cite web|url=https://www.howtor.com/sodium-polyacrylate-for-cables.html|title=Sodium polyacrylate in waterproof tape of cables|last=|first=|date=|website=|archive-url=|archive-date=|dead-url=|access-date=}} 12. ^{{citation|title=Artificial Snow|url=http://www.m2polymer.com/html/artificial_snow.html|publisher=M² Polymer Technologies, Inc.|accessdate=August 29, 2016}} 13. ^{{Cite web|url=https://www.howtor.com/sodium-polyacrylate-hot-cold-therapy-gel-pack.html|title=Sodium Polyacrylate for Hot Cold Therapy Gel Pack|last=|first=|date=|website=|archive-url=|archive-date=|dead-url=|access-date=}} 14. ^{{Cite web|url=https://www.supplieer.com/sodium-polyacrylate-safety/|title=The Safety of sodium polyacrylate for human|last=|first=|date=|website=|archive-url=|archive-date=|dead-url=|access-date=}} 2 : Acrylate polymers|Organic sodium salts |
