Description
9 i 1 1 A 1 j- PHOSPHATE- AND SILICATE-FREE LAUNDRY DETERGENT COMPOSITIONS
The invention relates to phosphate and silicate free aqueous washing compositions that contain alkali and a combination of a polycarboxylate and a phosphonate.
It is desirable to avoid having washing compositions containing phosphates and/or silicates. Phosphates are well known to be ecologically undesirable and indeed in certain countries are no longer permitted. Silicates have the disadvantage that they tend to form deposits in the particular washing machine in which they are used.
According to the invention there is provided a phosphate and silicate free aqueous washing composition comprising (i) 5-45% of alkali, (ii) 0.5-20% of polycarboxylate and (iii) 0.1-107. of phosphonate, the balance comprising water.
When preparing compositions according to the invention, the polycarboxylate and/ or the phosphonate can be formed in situ by adding the corresponding free acid which on contact with the alkali forms the salt or by adding the salt form per se.
All percentages given in the compositions according to the invention are by weight of the active compound or material and relate to the total composition.
Further, compositions according to the invention may contain further additives for example other sequestering agents and/or corrosion inhibitors.
Preferably in compositions according to the invention, the ratio Case 150-5302 of polycarboxylate to phosphonate is 1:1 to 30:1, more preferably 1.5:1 to 12:1.
Compositions according to the invention may be used as alkali donors in industrial washing processes. Preferably such a composition according to the invention comprises (i) 15-35%, more preferably 18-30% of alkali, (ii) 3-10%, more preferably 4-7% of polycarboxylate and (iii) 0.2-1.5%, more preferably 0.5-1.2% of phosphonate, the balance being water and one or more compounds selected from sequestering agents and corrosion inhibitors.
Compositions according to the invention may also be used as washing liquids for use in a dish washer. Such compositions must be free of any chlorine containing compounds. Preferably such a composition according to the invention comprises:
(i) 10-35%, more preferably 13-20% of alkali, (ii) 0.5-15%, more preferably 0.5-10.5% of polycarboxylate and (M) 0.2-5%, more preferably 0. 4-3% of phosphonate, the balance comprising water.
The pH of these compositions is preferably over 10.
Preferred alkali used in the aqueous compositions according to the invention are alkali metal -hydroxide or -carbonate, more preferably sodium or potassium hydroxide or carbonate. The alkali can be used in solid form or as a very strongly concentrated aqueous solution.
Preferably in a composition according to the invention the polycarboxylate is one that is preferably derived from medium to high molecular weight polymers (preferably having a molecular weight of 800 1 4 b c - 3 - Case 150-5302 to 500,000, more preferably 1,000-250,000, especially 4,000-120,000); more preferably it is derived from one of the following acids:
methacrylic acid, acrylic acid, a-hydroxyacrylic acid, maleic acid or copolymers thereof.
Such polycarboxylic acids are in aqueous solution. Preferably the polycarboxylic acid is in the form of an alkali metal salt, preferably sodium or potassium salts. Preferably the polymer is a polyaerylate polymer.
Preferred phosphonates are those derived from hydroxy Cl-4alkylene phosphonic acid or aminomethylene phosphonic acid or phosphonic Cl4alkylene carboxylic acid. More preferably the phosphonic acid is one derived from:
1-hydroxyethane-l,l-disphosphonic acid (HEDP), aminotri(methylenephosphonic acid) (ATMP), ethylene diamine tetra(methylene phosphonic acid) (EDTMP), Diethylene triamine penta(methylene phosphonic acid) (DETPMP), hexamethylene diamine tetra(methylene phosphonic acid), amine oxide tri(methylene phosphonic acid) and 2-phosphono butane -1,2,4-tricarboxylic acid (PBTC).
Preferably compositions according to the invention contain one or more sequestering agents selected from salts of nitrilotriacetic acid and citric acid. Preferably the amount of sequester ing agent used is from 320%, based on the weight of the composition Preferred salt forms are those derived from the alkali metals, e.g. sodium and potassium.
Where a composition according to the invention is to be used as dish washing machine liquid (and therefore does not contain any chlorine containing compounds), then it optionally includes one or more corrosion inhibitors. Preferred corrosion inhibitors are selected 4 a from sodium nitrite, benzotriazoles or tolyltriazoles. Preferably when a corrosion inhibitor is present it is preferably present in an amount selected from 0.5-1% of sodium nitrite and 0.2-0.4 of benzotriazole or tolyltriazole.
Compositions according to the invention when used as dish washing machine liquids (i.e. without the chlorine containing compounds) have extremely good wash and cleaning properties and also do not have the abovementioned disadvantages associated with phosphate and silicate containing washing liquids.
Compositions according to the invention when used as alkali donors in industrial washing liquids produce stable, strong alkali concentrates, which through the addition of anionic or nonionic surface active agents make up useful industrial washing liquids.
a D The invention will now be illustrated by the following examples in which all amounts are given in percent by weight of the composition.
Polyacrylic acid A has a molecular weight of 100,000 and is used as 29% solution of the half neutralised acid (sodium salt form), polyacrylic acid B has a molecular weight of 4,500 and is used as 49X solution, the sodium salt of nitrilo triacetic acid (NTA) is used as 40% solution, the diethylenetriamine penta(methylene phosphonic acid) (DETPMP) is used as 50% solution and the 1-hydroxyethane-l,l-diphosphonic acid (HEDP) is used as 60% solution, all solutions being in water.
