Observations with the Infrared Space Observatory led to a breakthrough in our understanding of the chemical composition and the lifecycle of cosmic grains. Now, a complete inventory of cosmic ices is possible and the nature of the carriers of the Unidentified Infra Red (UIR) bands can be better understood. A lot of new information has been collected for oxidic grains, including the detection of crystalline silicates in a large variety of environments. The paper will review what has been learned from ISO observations for oxygen-based dust grains. The ISO spectra contain quite a lot of features the carriers of which are still not identified. Among these features are the strong 21 and 30 micron bands which have been found in carbon-rich evolved stars. The paper will discuss the new constraints coming from ISO for the nature of the carriers of these features.
