The safety of Foot Powders and Sprays is established by selection of ingredients that are safe and suitable for this purpose. In addition, Foot Powders and Sprays are assessed for their potential to cause skin irritation or cause allergic reactions. Product safety is also established though strict adherence to the principles of Quality Assurance and Good Manufacturing Practices. This includes testing the compatibility of the product with packaging as well as shelf-life stability.

Companies include a phone number on their products where comments or complaints may be reported.
