What Causes Yellow Armpit Staining?
By Smart Marketing

Are you faced with tough stains on the underarms of your clothes when laundry day arrives? Are your white shirts tinged an unpleasant yellow that is difficult to remove? Your anti-perspirant could be the culprit!
Yellow armpit staining can be caused by many factors including an individual’s sweat composition. Your sweat consists of water, ammonia, urea, salts, and sugar, and on its own, is colourless and odourless. However, when your sweat reacts with chemicals such as active ingredients in your antiperspirant, laundry detergent, or bacteria, it can turn yellow and cause stubborn yellow stains.
The only circumstances under which your sweat may not be colourless is if you suffer from apocrine chromhidrosis, a rare condition which can cause your sweat to be green, blue, or black, dependent on the chemical modification in individual cases. If you think you are suffering from aprocrine chromhidrosis, contact your GP.
How To Avoid Yellow Pit Stains
If you are sick of unsightly yellow stains, it might be worth switching your anti-perspirant to a natural deodorant. These yellow stains are often caused by a chemical reaction between your sweat and the aluminium in your anti-perspirant, which causes your sweat to turn yellow and stick to your clothes. By switching to a natural deodorant such as those in the Salt of the Earth range, you can eliminate this ingredient while remaining protected against body odour.
