The viscosity of aqueous dispersions of normally solid organic peroxides may be advantageously lowered through the use of surfactants which are polyglyceryl esters of C6-C12 fatty acids. The reduction in viscosity facilitates milling the peroxides to reduce particle size and also provides dispersions of small particle size peroxides which may be readily poured or pumped. The aqueous dispersions are useful as components of pharmaceutical, personal care, and cleaning products and the like and are effective decolorizing agents for food products, industrial products and the like.

The disclosure provides methods and apparatuses for removing a yellow color of riboflavin in a lactose solution. The methods include exposing a lactose solution (e.g. milk) containing riboflavin to light under conditions that breakdown riboflavin comprised within the solution to thereby remove the yellow color of riboflavin. The conditions that breakdown include a specific wavelength of light (e.g. light having a wavelength of 360-475 nm) and a specific temperature range (e.g. a temperature of 0-80 C.). In certain embodiments, the duration of the treatment is such that the lactose solution is exposed to a total of 5-20 kW of light.
