Huffman, Absorption and scattering of light by small particles, John Wiley, New York 1983. The incident laser light interacts with the particle leading to absorption and scattering. Although the particles in a colloid are too small to see, they are big enough that they scatter light. The size distributions from three individual measurements show that the majority of ultrafine particles in RPMI medium are present as single particles or small agglomerates of two to three particles. It is non-irritating and non-allergenic, therefore it is claimed to be very suitable for Because of its small particles, the nano size Zinc Oxide does not scatter light and therefore does not appear white. Colloids are particles of an intermediate size that stay suspended in water and are too small to see. Publisher: John Wiley & Sons Page Count: 533. μm particles; B: 0.05 μm particles). It can occur when light travels in transparent solids and liquids, but is most C.F. DLS can only be used for smaller particle, best results if the particle sizes are smaller or close to wavelength of laser i.e. The light bounces off in different directions Riboflavin has a high absorbance in the purple part of the light spectrum (450 nm = 13153 abs/cm M), the remaining light passing through the solution would have a yellowish hue. Ultrafine particle size in RPMI medium was further analyzed by dynamic light scattering. The amount of IL-8 was determined by comparing the absorbance of the samples with standard recombinant human IL-8. Rayleigh scattering (named after the English physicist Lord Rayleigh) is the elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the light.

When used as an ingredient in sunscreen, Zinc Oxide, a mineral powder, is claimed to sit on the skin's surface scattering and absorbing ultraviolet rays without being absorbed into the skin.
