Linear viscoelastic aqueous liquid automatic dishwasher detergent composition having improved anti-filming properties

A linear viscoelastic aqueous liquid automatic dishwasher composition comprising approximately by weight:

• (a) 10 to 40% of at least one alkali metal detergent builder salt, said alkali metal detergent builder salt being selected from the group consisting of alkali metal tripolyphosphate, alkali metal pyrophosphate, alkali metal metaphosphate, alkali metal carbonate, alkali metal citrate and alkali metal nitrilotriacetate and mixtures thereof;
• (b) 0 to 20% alkali metal silicate;
• (c) 0 to 8% alkali metal hydroxide;
• (c) 0 to 5.0% chlorine bleach stable, water-dispersible, organic anionic detergent active material;
• (e) 0 to 1.5% chlorine bleach stable foam depressant;
• (f) chlorine bleach compound in an amount to provide 0.2 to 4% of available chlorine;
• (g) 0.1 to 2.0% of at least one cross-linked polyacrylic acid thickening agent having a molecular weight of from about 1,000,000 to 4,000,000;
• (h) 0.005 to 1.75 of a long chain fatty acid or an alkali metal salt of a fatty acid;
• (i) 0 to 15% of a non-cross-linked polyacrylate having a molecular weight of about 1,000 to 100,000;
• and
• (j) 0.1 to 5% of an inorganic anti-filming agent;
• and
• (k) balance being water, wherein said polyacrylic acid thickening agent being selected from the group consisting of acrylic acid or methacrylic acid, water-dispersible or water-soluble salts, esters, or amides thereof, and water-soluble copolymers of these acids or their salts, ester, or amides with each other or with one or more other ethylenically unsaturated monomers, wherein substantially all of the normally solid components of the composition are present dissolved in the aqueous phase, except the inorganic anti-filming agent and substantially all of the water in the composition is tightly bound to the cross-linked polyacrylic acid thickening agent, said composition having a bulk density of from 1.26 g/cm.sup.3 to 1.42 g/cm.sup.3 and said composition does not exhibit phase separation and remains homogenous, when said composition is centrifuged at 1000 rpm for 30 minutes.
