Abstract:
An aqueous, pink colored, linear viscoelastic liquid automatic dishwasher detergent comprising approximately by weight:(a) 1% to 25% of an alkali metal detergent builder salt selected from the group consisting of alkali metal salts of tripolyphosphate, metaphosphate, pyrophosphate, hexa-metaphosphate, orthophosphate, carbonate, citrate, and nitrilotriacetate;(b) 1% to 20% of an alkali metal silicate;(c) 1% to 10% of at least one alkali metal hydroxide;(d) 0.1% to 5% of an alkali metal mono- and/or di- (C.sub.8 -C.sub.11) alkyl diphenyl oxide mono- and/or di-sulphate;(e) 0.05% to 1.8% of a chlorine bleach stable foam depressant selected from the group consisting of an alkyl acid phosphate ester, an alkyl phosphoric acid ester wherein said esters contain one or two C12-C20 alkyl groups, ethoxylated alkyl groups, and mixtures thereof;(f) chlorine bleach compound in an amount to provide about 0.2 to 4% of available chlorine;(g) 0.1% to 1.5% of a hydrophilic cross-linked polyacrylic acid thickening agent having a molecular weight from about 500,000 to 5,000,000;(h) 0.1% to 4% of a non-crosslinked polyacrylate polymer having a molecular weight from about 2,000 to 20,000;(i) 0.001% to 0.5% of a red F.sub.2 O.sub.3 pigment; (j) 0.05% to 1% of a long chain fatty acid or a metal salt of a long chain fatty acid; and(k) the balance being water, wherein the composition has chromaticity coordinate values coordinates of x from about 0.3142 to about 0.3242 and y from about 0.3233 to about 0.3333.
