Abstract:
1. A slow release solid tablet composition for industrial water systems which comprises: a) from about 2 through about 40% by weight of an amphiphilic, liquid compound of Formula (I) b) from about 20 through about 40% by weight of a hydrophilic polymer selected from hydroxypropyl methylcellulose (HPMC), methyl cellulose (MC), hydroxypropylcellulose (HPC), hydroxyethylcellulose (HEC), and polyethylene glycol (PEG), or mixtures of them; and c) from about 8 through about 50% by weight of an ionic compression agent selected from dicalcium phosphate (DCP) and CaSO d) from 0 through about 50% by weight of a scale inhibitor selected from polyacrylate, acrylate copolymers and maleate copolymers wherein the polymers are of low to medium molecular weight, [e.g. M e) from 0 through about 20% by weight of a corrosion inhibitor selected from ZnCl f) that the total of the components of a)-e), plus when present any other typical tablet components, equal 100% by weight of the tablet composition; and
