Talk:Aluminium hydroxide

The "Uses" section has 100M tonnes/year production, 90% of which is for aluminum metal production. I can believe the second of these figures. But given that aluminum metal production 51.5M tonnes/year September 2013-August 2014 ^[1], and the molar mass ratio of Al(OH)₃:Al is 78:27, Al(OH)₃ production for the aluminum metal industry is at least 144M tonnes/year, probably over 150M to account for yield losses. This brings the world total up to around 160M tonnes.

The same reference also has world alumina (Al₂O₃) production, which it gives as 108M tonnes 9/2013-8/2014,^[2] which would put Al(OH)₂ production above 160M tonnes/year. Hazelsct (talk) 19:17, 7 October 2014 (UTC)

I look on the label of my "Pearl Drops" toothpaste and see that it has Aluminum Hydroxide and read this article to find out why it would be in there. The part of the article that says "Red Mud" is toxic makes me wonder whether Aluminum Hydroxide is toxic, and why it's in my toothpaste.

Any toxicity associated with red mud may have nothing to do with aluminum hydroxide, and the term toxic is vague anyway ("the dose makes the poison"). Considering all the pharmaceutical applications of aluminum hydroxide listed in this article, you shouldn't worry that the small amount in your toothpaste will cause any problems. -- Ed (Edgar181) 20:03, 1 December 2015 (UTC)

I ran into this and was about to simply flag it with a "fact" tag before I went here and saw that people were already complaining. So I instead rewrote the section. The person who made that edit is confusing red mud (a waste product of aluminum hydroxide production) with aluminum hydroxide itself, and confusing "caustic" (from the sodium hydroxide in the red mud) with "toxic". -- 213.176.153.100 (talk) 10:42, 6 December 2015 (UTC)

 The manufacturer of Alhydrogel was incorrectly listed as Brenntag.  Brenntag is a chemical distributor.  They do not manufacture any of the products that they sell.  Corrected to the actual trademark holder for Alhydrogel, and included reference link to Sergeant Adjuvant website.  — Preceding unsigned comment added by 24.191.231.29 (talk) 17:27, 5 March 2016 (UTC)

This edit removed a sourced paragraph from this section, saying "remove nonsense - not a reliable source".

However aluminum has been linked in studies to Autism and Alzheimers and is synergistic in it's damaging effects when combined with mercury to cause greater harm.^[1]

The assertion was initially inserted without citing a supporting source. I reverted the insertion, but later unreverted and added a source supplied to me on my talk page by the original inserter. I did not vet the source at the time, and I now see that its reliability is called into question at Association of American Physicians and Surgeons#Journal of American Physicians and Surgeons. it looks to me as if, with this supporting source, this does not meet the requirements of WP:DUE. The assertion (which does not say flatly that aluminum is linked to Autism, Alzheimers, etc, -- it says that it "has been linked in studies ..") might meet those requirements with a better supporting source cited. If it reappears, it should probably be balanced with WP:RS supported asertions giving alternative POVs. Wtmitchell (talk) (earlier Boracay Bill) 10:41, 19 September 2018 (UTC)

Apart from the grocer's apostrophe there is a problem with saying "linked to" - a weasel expression beloved of sensational sources. AFAIK it's a long-discredited myth that aluminium "causes" AD. Alexbrn (talk) 11:17, 19 September 2018 (UTC)

The publication in Journal of American Physicians and Surgeons mentioned above is written by a journalist, not a PhD or MD. The first sentence is "Aluminum is a neurotoxin,.." Just sayin'.--Smokefoot (talk) 11:59, 19 September 2018 (UTC)

According to this article the solubility of Aluminium hydroxide is 0.0001 g/100 ml which is equal to 0.001 g/l, while calculations from k_sp suggests a much lower value of 0.0000002262 g/l which is equal to 0.00000002262 g/100 ml. Also the k_sp of Aluminium hydroxide according to this article is 3×10^-34 while truly it is 1.9×10^-33.
