Abstract

The scent-containing carrier on a gel base contains a water- and/or alcohol-containing polyurethane-polyurea polymer as carrier material. This carrier is obtained by reacting isocyanato-containing prepolymers of polyethers containing at least 40% by weight of ethylene oxide units with di- or polyamines or water as chain extender in water and/or alcohols in the presence of scents.
