Bloomberg News hired a lab to analyze samples of store brand aloe gel purchased at Wal-Mart, Target, and CVS. As the first or second ingredient (after water), all the products listed aloe barbadensis leaf juice — another name for aloe vera. None of the samples contained any. From Bloomberg:
Aloe's three chemical markers — acemannan, malic acid and glucose — were absent in the tests for Wal-Mart, Target and CVS products conducted by a lab hired by Bloomberg News. The three samples contained a cheaper element called maltodextrin, a sugar sometimes used to imitate aloe. The gel that's sold at another retailer, Walgreens, contained one marker, malic acid, but not the other two. That means the presence of aloe can't be confirmed or ruled out, said Ken Jones, an independent industry consultant based in Chapala, Mexico.
Target Corp. declined to comment. Spokesmen for Wal-Mart Stores Inc., CVS Health Corp. and Walgreens Boots Alliance Inc. said their suppliers confirmed to them that their products were authentic.
