Magnesium Aluminium Silicate

I got redirected to this page when I typed in the term "Magnesium Aluminium Silicate " . This compound is listed as one of the ingredients in my Waleda toothpaste . Does anybody know what its purpose is in terms of toothpaste manufacture ? Also ; is it the same as pyrope ? Thank you . — Preceding unsigned comment added by 109.155.27.31 (talk) 18:44, 13 January 2015 (UTC)[reply]

Pyrope is certainly a magnesium aluminium silicate, but to paraphrase John Lennon, it is not the only one. In toothpaste the most likely mineral species to have been identified as "magnesium aluminium silicate" would be phlogopite mica, which can be mined and refined or generated synthetically. The synthetic form, usually actually fluorphlogopite (so called because the hydroxyl groups in regular phlogopite have been replaced by a fluorine atom), is almost pure white (hence, aesthetically pleasing in a toothpaste) and is used both as a bulking agent (it's cheap!) and as a mild abrasive (it scours the plaque off your teeth!) in toothpaste. Bringing this reply back to a Wikipedia editorial issue, I have no ideas why the magnesium aluminium silicate redirect points here, and I'll see if there is a more appropriate place for it. Pyrop e

Mineral Identification section needs cleanup. Reads like an advice column. Needs addition of key separations from similar minerals. SauliH 06:01, 26 January 2007 (UTC)[reply]
