  • Patent number: 5482600
    Abstract: The present invention process involves the exposure of antiperspirant salt solutions to ultraviolet light to cause lightening in color. The ultraviolet light can be in the wavelength range of 180 to 400 nanometers, with the longer wavelengths preferred and at an exposure time of 1 to 120 minutes. The color of the antiperspirant solutions treated with ultraviolet light approaches the color of water, commonly known in the cosmetic industry as water white. These exceptionally low color antiperspirant salt solutions are useful in development of clear and colorless antiperspirant gels, roll-ons and stick formulations.
