Other treatments for skin cancers including melanomas is the use of Cansalve cream. It will kill any external malignant growth from the roots up within days. Only kills malignant growth and leaves the rest alone. —Preceding unsigned comment added by 124.187.38.98 (talk) 01:58, 20 August 2008 (UTC)[reply]

neutrality?

I nominated for a neutrality check because, although rose bengal is used frequently in medicine and science labs (including my own), this article focuses almost entirely on a set of products by some biotech company. —Preceding unsigned comment added by Belizefan (talk • contribs) 16:54, 5 November 2010 (UTC)[reply]

Etymology

So, who knows where the name comes from? "Rose" is obviously its color, but....? DS (talk) 14:43, 29 November 2011 (UTC)[reply]

"Rose Bengal is red in base and is about the same color in dilute solution as the decorative Indian happiness wart color worn by Bengali women at the center of the hairline to symbolize marriage. This was the source of its name." ^[1] --132.199.54.54 (talk) 11:50, 30 October 2017 (UTC)[reply]

Molecular diagrams

Sigma-Aldrich (http://www.sigmaaldrich.com/) and Tokyo Chemical Industry Co., Ltd (http://www.tcichemicals.com/) present "Rose Bengal lactone" (CAS Number 4159-77-7) as

and "Rose Bengal disodium salt" (CAS Number 632-69-9) as

It appears that CAS number 11121-48-5 is inoperative.

Rose bengal is a photodynamic therapy agent.

Solubility of variants

Original rb is described above as 'oily' - does that imply insoluble in water ? How soluble in water is rb, the disodium salt, and PV-10 ? - Rod57 (talk) 13:15, 26 April 2016 (UTC)[reply]

Use as a food coloring

According to the Japanese entry this is also used as a food coloring in Japan: red 105 101.50.43.2 (talk) 08:22, 4 January 2023 (UTC)[reply]
