DETERGENT TABLET

摘要

A multi-phase detergent tablet for use in a washing machine, the tablet comprising a first phase in adhesive contact with one or more second phases, at least one second phase being in the form of a compressed particulate solid incorporating liquid adhesive and having an average porosity of less than about 0.15 ml/g. The liquid adhesive is preferably selected from polyethylene glycols having an average molecular weight in the range from about 200 to about 700 and is preferably applied by post-addition to the particulate solid prior to compression. The multi-phase tablets provide improved interphase adhesivity, robustness and strength together with excellent dissolution and cleaning characteristics.
