message: By the end of the 20th century, many products that formerly contained TSP are now manufactured with TSP'
doesn't make sense, I think it's intended to say "without TSP" but I'm not sure enough to want to edit it to that effect.

message: Up until the 2010 ban on phosphates in the U.S. for consumer dishwashing detergent, I don't think TSP was even an ingredient. Anyone editing the article to say TSP was in automatic dishwasher detergent, I want to see good references. I am not too sure about laundry detergents, but since they have been free of phosphates for a long time now, I don't know if it would be easy to find an historical source about them. Maybe they had TSP in them... I think they might have, or at least some of them might have.
As for dishwashing detergent, I believe the phosphates responsible for the water softening were things like STTP, which is Sodium tripolyphosphate. I changed the article to note the fact that these compounds are easy to get confused. 
There was a long NY Times article on dishwashing, but since it never mentioned TSP, I removed the source, mainly because this source made no mention of any specific compounds responsible for either the softening or algae growth effects. I think people falsely attribute TSP to the phosphate chemicals formerly used to soften dishwashing water. I like to saw logs! (talk) 04:07, 27 March 2011 (UTC)

message: I followed the "^ Hotton, Peter (26 August 2010). "Handyman on Call". The Boston Globe." link and it makes no reference to any other materials relative to TSP at all, you can hardly call it a reference supporting the statement that substitute cleaning agents aren't as effective.
I'm sure there is literature out there that has information on this. Surely sodium carbonate and sodium silicates are the most comparable in terms of applications. In my opinion silicates are better cleaners anyway, you just have to look out for corrosion issues.  — Preceding unsigned comment added by 81.138.11.111 (talk) 09:48, 4 February 2014 (UTC)

message: On Jun 24, 2014, the article includes:
Food additive[edit]
Sodium phosphates (monosodium phosphate, disodium phosphate, and trisodium phosphate) are approved as a food additive in the EU; used as emulsifying agents, E339.[12]
If you click the E339 link, however, the table has:
E339	Sodium phosphates (i) Monosodium phosphate (ii) Disodium phosphate (iii) Trisodium phosphate	antioxidant	Approved in the EU.[17]
where the "antioxidant" value is in a column headed "Purpose".  So instead of saying "used as emulsifying agents", IMHO it seems like it ought to be "used as antioxidant".

thread_title:  the "Food Additive" section says "emulsifier", but the E number listed is for "antioxidant" 

message: The article classifies trisodium phosphate as H318, yet the ECHA website which gives the currently accepted classification for thousands of chemicals gives the material a classification of H319.
Here it is:

message: I've seen the formula Na3PO4·12 H2O referred to as sodium phosphate tribasic 12-hydrate (for example, by chemical.net https://www.chemical.net/sodium-phosphate-tribasic-12-hydrate-crystal-3). What exactly does the tribasic in this name mean?  — Preceding unsigned comment added by Secretkeeper12 (talk • contribs) 04:26, 3 October 2016 (UTC)
replies: text: Tribasic refers to the number of basic molecules (NaOH) that reacted with each molecule of H3PO4 to form the product. Orthophosphoric acid is a triprotic acid, and therefore there are three positions where it can react with a molecule of a base. 71.248.161.176 (talk) 03:37, 31 October 2016 (UTC)

message: "While TSP is not toxic per se,"
The MSDS http://www.ilo.org/dyn/icsc/showcard.display?p_lang=en&p_card_id=1178 also http://ecswestern.org/filebrowser/download/2615 say the following:
Ingestion	
ACUTE HAZARDS / SYMPTOMS
Cough. Sore throat. Abdominal pain. Burning sensation. Shock or collapse. 	
PREVENTION
Do not eat, drink, or smoke during work. Wash hands before eating. 	
FIRST AID / FIRE-FIGHTING
Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Rest. Refer immediately for medical attention. 
Anytime I see something that says "Do NOT induce vomiting" or "Refer immediately for medical attention" puts up red flags for me.  
If it isn't toxic, why the need for immediate medical attention?
