Petroleum jelly smell when pure. It does not oxidize on exposure to the air and is not readily acted on by chemical reagents. It is insoluble in water. It is soluble in dichloromethane, chloroform, benzene, diethyl ether, carbon disulfide and oil of turpentine. Depending on the specific application of petroleum jelly, it may be USP, B.P., or Ph. Eur. grade. This pertains to the processing and handling of the petroleum jelly so it is suitable for medicinal and personal-care applications. Because they feel similar when applied to human skin, there is a common misconception that petroleum jelly and glycerol (glycerine) are physically
Jelly-falls can lead zones around jelly-falls to become hypoxic and inhospitable to larger scavengers. Researching jelly-falls relies on direct observational data such as video, photography, or benthic trawls. This means that jelly-falls are not always observed in the time period in which they exist. Because jelly-falls can be fully processed and degraded within a number of hours by scavengers and the fact that some jelly-falls will not sink below 500m in tropical and subtropical waters, the importance and prevalence of jelly-falls may be underestimated. Jelly-falls Jelly-falls are marine carbon cycling events whereby gelatinous zooplankton sink to the seafloor and enhance carbon
