Description

DETERGENT COMPOSITIONS COMPRISING A MODIFIED POLYAMINOAMIDE

FIELD OF THE INVENTION The present application relates to detergent compositions which have good soil removal properties and good dispersing properties for hydrophobic particulate soil, especially clay minerals through the use of modified polyaminoamides. BACKGROUND OF THE INVENTION Certain polymers are known to be useful for preventing the redeposition of soil by stabilizing the soil in the wash liquor. Amongst these are carboxymethylcellulose (CMC), huminic acid, polyacrylic acid and copolymers of maleic acid and acrylic acid (see Powdered Detergents, Editor: Michael S. Showell, Surfactant Sci. Ser.,Vol. 71, Marcel Decker, New York 1998, pages 111-114; Liquid Detergents, Editor: Kuo-Yann Lai, Surfactant Sci. Ser., Vol. 67, Marcel Decker, New York 1997, page 303). Polyaminoamides are known to be polymers whose backbone chain contains both amino functionalities (NH) and amide functionalities (NH-C(O)). Modified polyaminoamides containing polyetlier side chains, which are attached to the amino nitrogen atoms of the polymer backbone and, if present, to the amino nitrogen atoms of the end-groups of the polymer, are known e.g. from GB 1218394, EP 1025839, EP 1192941 and WO03/050219. In the modified polyaminoamides of prior art the number average of the repeating units in the polyether side chain is in most cases from 1 to 6. Up to now, polyaminoamides have neither been suggested as anti- redeposition agents nor to be useful for assisting in soil removal. Consequently, there is ongoing need for compounds which are useful as detergent auxiliaries for preventing redeposition of soil and for assisting in soil removal.

Since the non-modified polyaminoamides have a linear stmcture, the number average of the molecular weight can be determined from the ratio of the integrals of the NMR-signals. Modification Of The Non-Modified Polyaminoamide

The modified polyaminoamide for use the detergent composition of the claimed application may be produced by the general process: i) reacting the non-modified polyaminoamide with at least 10 moles, per mol of amino hydrogens in the non-modified polyaminoamide, of at least one epoxide of formula (XIII)

wherein R¹ and R² are as defined for formula (II); ii) reacting the modified polyaminoamide of step i) with at least one alkylating moiety, formula (IV) [-RX], wherein R and X are as defined above in formula (IV), thereby obtaining a cationically modified polyaminoamide; and iii) optionally esterifying/etherifying the hydroxyl groups in the cationically modified polyaminamide obtained in step ii) with: (a) sulfuric acid or phosphoric acid or with an ester-forming derivative thereof; or (b) etherification of the hydroxyl groups in the cationically modified polyaminamide obtained in step ii) with a compound of the formula (XIV) L-B³-A', wherein A' of formula (XIV) is selected from -COOH, -S0₃H and -PO(OH) ₂, B³ of formula (XIV) is selected from Cι-C₆-alkandiyl; and L of formula (XIV) is a leaving group, which can be replaced by nucleophiles. Step i) of the process of the application can be achieved in analogy to know methods of alkoxylating amines. Preferably, the non-modified polyaminoamide starting material is reacted in a first step with an epoxide of formula (XIII) in the absence of a catalyst. A polyaminoamide where most or all of the amino hydrogens are replaced by a radical CH₂-CR'R²-OH, wherein R¹ and R² of formula (II) is as above with p of formula (II) being equal to 1. To obtain modified polyamidoamines with p of formula (II) being greater than 1, further amounts of epoxide of formula (XIII) is used, preferably in the presence of a base as catalyst. Examples of suitable bases are alkali metal and alkaline earth metal hydroxides, alkali metal alkoxides, sodium hydride, calcium hydride and alkali metal carbonates. Preferred bases are the alkali metal hydroxides and alkali metal alkoxides. The base is generally used in an amount of from 0.05 to 10% by weight, preferably 0.5 to 2 % by weight, based on the total amount of the starting materials. The alkoxylated polyaminoamides obtained in step i) are then reacted with an alkylating moiety (step ii). As used herein, the term "alkylating moiety" refers to a formula (IV) [-RX], wherein R and X is as defined above in formula (IV). See generally Houben-Weyl, Methoden der organischen Chemie, 4^th ed., vol. XI/2, p. 608-613. The amount of alkylating moiety determines the amount of quatemization of the amino groups in the polymer backbone, i.e. the amount of quatemized moieties shown in formulae (a), (bl) and (b2). In general, the amount of the alkylating moiety is from 0.1 mol to 2 mol, especially from 0.5 mol to 1.5 mol, and more preferred from 0.7 mol to 1.2 mol per mol of amino groups in the modified polyaminoamide obtained in step i). In general, the amount of epoxides used as alkylating agent is from 0.1 mol to 2 mol, especially from 0.5 mol to 2 mol and more preferred from 0.7 mol to 1.5 mol per mol of amino groups in the modified polyaminoamide obtained in step i). The thus obtainable cationic modified polyaminoamides carry hydroxyl groups as terminal groups of the formula (II) and, if present, in the form of groups Alk-OH of formulae (III), when A of formula (III) is selected as hydrogen. These hydroxyl groups can be esterified in step iii), thereby esterfied polyaminoamides, wherein A of formulae (II) and (III) is selected from - PO(OH)₂ and -S(0)₂OH.

The introduction of the formula (XIV) L-B³-A' at the termini of polyether side chains, especially of a carboxylic acid functionality -B₂-COOH of formulae (II) and (III) can be achieved by etherification of terminal hydroxyl groups with halocarboxylic acids Hal-B²- COOH {Hal = halogen, especially chlorine or bromine, B² of formulae (II) and (III) as defined above, especially with α-halocarboxylic acids such as chloroacetic acid. The etherification can be performed in analogy to known methods for the production of caboxy methylcellulose (Houben- Weyl E20, p. 2072-2076 and Ullman, 5th ed., A5, p.477-478).

Step I. Synthesis of non-modified polyaminoamides

At room temperature (15-20°C) charge a polyalkylenepolyamine into a 2 1 glass round bottom flask equipped with a destination bridge. Purge the reactor with nitrogen and add x g (x is defined below in Table 1) of deionized water. The temperature will rise to about 50°C. Heat the mixture to 60°C and add adipic acid within 5 minutes. The temperature will rise to about 100°C. Heat the reaction mixture to 120°C and stir at this temperature for one hour. Slowly increase the temperature to 180-190°C and distill off water and unreacted amine for at least 3 hours until the amount of condensated water had reached at least the theoretical value for a fully condensed product and the acid number is below 10 mg KOH/g. Cool the reaction mixture to between 120°C and 180°C and dilute with y g (y defined below) of deionized water to give a white or slightly yellow polyaminoamide solution with an active content from 60 to 90% by weight. Depending on the active content, the degree of condensation and the identity of the amine and acid component the product is a liquid of high viscosity or a solid. The starting materials and the amounts employed are given in Table 1. Table 1

Reaction with 1 mol ethylene oxide per mol NH-groups Charge the aqueous solution of the polyaminoamide into a 2 1 metal reactor and then render it inert by applying 3 to 5 bar of nitrogen 3 times. Heat the reactor contents to 90-130°C and add the required amount of ethylene oxide was added in portions (total amount equimolar to the amino hydrogens present in the polyaminoamide) in such a way so as to slowly raise the pressure. Increase the pressure further by adding nitrogen until a pressure of 500-800 kPa (5-8 bar) is reached and then stir the reaction mixture at 90-130°C until the pressure remains constant. Cool the reaction mixture to 70-80° C. Flush the reactor with 300 kPa (3 bar) of nitrogen and remove residual ethylene oxide on a rotary evaporator. The resulting alkoxylated polyaminoamide is yellow or lightly brown in color and depending on the active content, the degree of condensation and the identity of the amine and acid component the product is a liquid of high viscosity or a solid.
