Unlike pump based deodourants where the fragrance is released only when the pump is pressed and smell lasts only few seconds, the Gel releases fragrance continuously at very low concentration at all times. Here there is no danger of spillage, like in Liquid air fresheners. They do not damage any surface. They are very safe to use and handle. They do not contain any hazardous ingradients. They are Environmentally friendly as they do not contain any volatile solvent.
