Properties of dust in the interplanetary dust cloud and in cometary comae are approached through polarimetric observations, including polarimetric imaging and analyses of the phase angle and wavelength dependences. Local changes are clues to changes in the properties of the dust particles. They are likely to correspond to modifications in the size distribution and to evolution processes related to the evaporation (or alteration) of ices and organics partly constituting some dust particles
