Definitions
- the present invention relates to alkoxylated polyalkyleneimine hydrophobic soil dispersants which are suitable for use as soil dispersant in applications.
- Soil dispersants act by sequestering dirt once it is dissolved or dispersed in the laundry liquor and keeps the suspended soil in the laundry liquor where it can be carried away during the normal rinsing process.
- bleaching agents especially peroxygen bleaches which are formulated into both liquid and granular laundry detergent compositions
- the formulator must consider the instability of a particular soil dispersant toward bleach.
- Many sucessful dispersants have polyalkyleneamine or polyalkyleneimine backbones which are susceptible to oxidation at the amine functionalities and potentially to breakdown or fragmentation by bleaching agents which may be present. From another view, the interaction of bleaching agents with these polyalkyleneimine- based dispersants depletes the amount of bleach present therefore affecting the bleaching performance.
- polyalkyleneimines having a backbone molecular weight of from about 600 daltons to about 25000 daltons wherein the backbone nitrogens have been substituted by an average degree of mixed alkyleneoxylation per N-H unit of from 12 to about 50 alkyleneoxy units provides an enhanced hydrophobic soil dispersant which is compatible with bleach.
- the polyamine backbone is first modified by placement of from 1 to 10 propyleneoxy units, butyleneoxy units, and mixtures thereof followed by ethyleneoxy units such that the total degree of alkyleneoxylation does not exceed about 50 units.
- the alkoxy- lated polyalkyleneimines of the present invention are suitable for use in high and low density granular, heavy duty and light duty liquids, as well as laundry bar detergent compositions.
- the present invention relates to a soil dispersant having the formula:
- R is C -C 6 linear alkylene, C 3 -C 6 branched alkylene, and mixtures thereof; B is a continuation by branching; E is an alkyleneoxy unit having the formula:
- R 1 is 1, 2 -propylene, 1, 2 -butylene, and mixtures thereof;
- R 2 is ethylene;
- R 3 is hydrogen, C ⁇ -C alkyl, and mixtures therof ;
- m is from about 1 to about 10;
- n is from about 10 to about 40;
- w, x and y are each independently from about 4 to about 200; provided at least one - (R 1 0) unit is attached to the backbone prior to attachment of an - (R 2 0) unit and further provided m + n is at least 12.
- the present invention relates to polyalkyleneimine dispersants which are polyalkyleneoxy substituted wherein propyleneoxy units, butyleneoxy units, and mixtures thereof are attached to the back- bone nitrogens prior to subsequent attachment of polyethyleneoxy units.
- the polyamine backbones of the present invention have the general formular: E B
- backbones prior to subsequent modification comprise primary, secondary and tertiary arnine nitrogens connected by R "linking" units.
- the backbones are comprised of essentially three types of units, which may be randomly distributed along the chain.
- the units which make up the polyalkyleneimine backbones are primary units having the formula:
- R is C -C 6 linear alkylene, C 3 -C 6 branched alkylene, and mixtures therof, preferred branched alkylene is 1, 2 -propylene, preferred R is ethylene.
- the preferred polyalkyleneimines of the present invention have backbones which comprise the same R unit, for example, all units are ethylene. Most preferred backbone comprises R groups which are all ethylene units.
- polyalkyleneimines of the present invention are modified by substitution of each N-H unit hydrogen with an alkyleneoxy unit having the formula:
- R 1 is 1, 2 -propylene, 1, 2 -butylene, and mixtures thereof, prefeably 1, 2 -propylene.
- R 2 is ethylene.
- R 3 is hydrogen, C 1 -C 4 alkyl, and mixtures thereof, preferably hydrogen or methyl, more preferably hydrogen.
- at least one propyleneoxy or butyleneoxy unit must be attached to the backbone nitrogen units prior to substitution with any other alkyleneoxy unit.
- the value of the index m is from about 1, preferably from about 2 to about 10, prefeably to about 6, more preferably to about 5.
- the value of the index n is from about 10, prefeably from about 15, more preferably from about 20 to about 40, preferably to about 35, more preferably to about 30.
- m + n is prefeably at least 12, more preferably from about 15, most prefeably from about 20 to about 40, more preferably to about 35.
- An example of a preferred polyalkyleneoxy substituent comprises three 1, 2 -propyleneoxy units prior to sub- sequent ethoxylation, especially when the rectifge value of m + n is about 30.
- the preferred molecular weight for the polyamine backbones is from about 600 daltons, preferably from about 1200 daltons, more preferably from about 1800 daltons, most preferably from about 2000 daltons to about 25000 daltons, preferably to about 20000 daltons, more preferably to about 15000 daltons, most preferably 5000 daltons.
- An example of a preferred molecular weight for a polyethyleneimine backbone is 3000 daltons.
- the indices x and y needed to achieve the preferred molecular weights will vary depending upon the R moiety which comprises the backbone. For example, when R is ethylene a backbone unit averages about 43 gm and when R is hexylene a backbone unit averages about 99 gm.
- the polyamines of the present invention can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc.
- a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc.
- Specific methods for preparing these polyamine backbones are disclosed in U.S. Patent 2,182,306, Ulrich et al . , issued December 5, 1939; U.S. Patent 3,033.746, Mayle et al . , issued May 8, 1962; U.S. Patent 2,208,095, Esselmann et al . , issued July 16, 1940; U.S Patent 2,806,839. Crowther, issued September 17, 1957; and U.S Patent 2,553,696, Wilson, issued May 21, 1951; all herein incoporated by reference.
- R means —CH 2 —CH—
- the polyethyleneimine thus represented has an average backbone molecular weight of about 3000

- R 2 is ethylene
- R 3 is hydrogen
- m + n is equal to about 30.
- the modification of the N-H units in the polymer with propylene oxide, butylene oxide and ethylene oxide units is carried out by first reacting the polymer, preferably polyethyleneimine, with propylene oxide, butylene oxide and mixtures thereof and then adding ethylene oxide.
- polyethylenei- mine is first reacted with propylene oxide in the presence of up to about 70 % by weight of water at a temperature of from 25 to 150°C in an autoclave fitted with a stirrer.
- propylene oxide is added in such an amount that nearly all hydrogen atoms of the N-H-groups of the polyethylenei- mine are converted into hydroxy propyl groups.
- the water is then removed from the autoclave.
- a basic catalyst for example sodium methylate, potassium tertiary buty- late, potassium hydroxide, sodium hydroxide, sodium hydride, potassium hydride or an alkaline ion exchanger in an amount of 0,1 to 15 %, by weight with reference to the addition product obtained in the first step of the propoxylation
- further amounts of propylene oxide are added to the reaction product of the first step so that a propoxylated polyethyleneimine is obtained which contains 1-10, preferably 2 to 5, most preferably 3 to 4, propylene oxide units per N-H group of the polymer.
- the second step is carried out for instance at temperatures of from 60 to
