ETHOXYLATED AMINE COMPOUNDS HAVING CLAY SOIL
REMOVAL/ANTI-~EDEPOSITION PROPERTIES USEFUL
IN DETERGENT COMPOSITIONS
'I Down N. Rubingh Eugene PO ~osselink TECHNICAL FIELD
The present application relaxes to ethoxylated amine , compounds having clay-soil removal/anti-redeposition properties when used in detergent compositions.
AYE particularly important property of a detergent composition is its ability to remove particulate type soils from a variety of i fabrics during laundering. Perhaps the most important particulate soils are the clay-type soils. Clay soil particles generally ( comprise negatively charged layers of aluminosilicates and post-¦15 lively charged cations (e.g. calcium) which are positioned between and hold together the negatively charged layers.
A variety of models can be proposed for compounds which would shave clay soil removal properties, One model requires that thy compound have two distinct characteristics. The first is the ,~`20 ability of the compound to adsorb onto the negatively charged slayers of the clay particle. The second is the ability of the compound, once adsorbed, to push apart (swell) the negatively charged layers so that the clay particle loses its cohesive force Andy can be removed in the wash water.
one class of clay-soil removal compounds which appears to work according to this model are the polyethoxy zwitterionic surfactants disclosed in US. Patent 4,301,044 to Gentler et at., issue Nabber 17, 1981. Representative of such compounds are those having the formula:
R1 No -(CH2)x~-O-(CH2CH20)ySO3 SHEA
wherein R1 is a C14-C20 alkyd group; x is 1 or an integer of from 3 to 5; and y is from 6 to 12. See also US. Patent 3,929,678 to ` Laughlin et at. 3 issued December 30, 1975 (detergent composition containing polyethoxy zwitterionic surfactant plus other detergent `: ;

Patent 4,165,334 to Gosselink et at., issued AU9LISt '21, 1979 (sulfonium-type polyethoxy zwitterionic surfactants).
These polye~hoxy zwitterionic surfactants are generally computable with other detergent surfactants such as the non ionic, ;10 zwitterionic and ampholytic types. However, as indicated in the Gentler et at. patent, most anionic surfactants interfere with the particulate soil removal performance of these compounds; anionic soils such as fatty acids likewise interfere. Because anionic detergent sur~actants form the most important class of such materials for use in deterrent compositions, the lack of compute-ability between these polyethoxy zwitterionic surfactants and anionic surfactants poses a significant handicap where particulate clue) soil removal is desired.
In addition to clay soil removal, one of the other properties mentioned in the Laughlin et at. patents with regard to these polyethoxy zwitteribnic surfactants is the ability to keep the removed soil in suspension during the laundering cycle. Soil which is removed from the fabric and suspended in the wash water Icon redeposit onto the surface of the fabric. This redeposited .25 soil causes a dulling or "graying" effect which is especially noticeable on white fabrics. Because soil is normally hydropho-big, this graying effect is a particularly important problem for those fabrics made in total or in part from hydrophobic fibers, e.g. polyester.
To minimize this problem, anti-redeposition or whiteness maintenance agents can be included in the detergent composition.
Besides the previously mentioned polyethoxy zwitterionic surface tents, there are a variety of other compounds which can be used as anti-re~eposition agents. One class of agents are the water-soluble copolymers of acrylic or methacrylic acid with acrylic or methacrylic acid-ethylene oxide condensates disclosed in US.

While effective to keep soil suspended, these 1, compounds may lack additional clay soil removal properties.
Moreover, as disclosed in the Doyle and Jean et at. patents, mixtures of compounds can be required to achieve the anti-redeposition benefit. To the extent that there are combined anti-redeposition/clay soil removal benefits as disclosed in the ; Camber patent mixtures ox compounds are also required.

The ethoxylated amine compounds of the present invention provide clay soil removal benefits while being anionic detergent surfactant compatible. At most wash oh's, it is believed that the nitrogen atoms of these compounds are partially protonated. The resulting positively charged centers (and remaining polar nitrogen atoms) are believed to aid in the adsorption of the compound onto the negatively charged layers of the clay particle. It is also believed that the hydrophilic ethics units of the compound swell the clay particle so what it loses its cohesive character and is swept away in the wash water.
The anti-redeposition benefits provided by these ethoxylated amine are also believed to by due to the formation of positively charged centers together with the remaining polar nitrogens, in Ills adsorption onto soil suspended in the wash water. As more and more of these compounds adsorb onto the suspended soil, it becomes encased within a hydrophilic layer provided by the attached ethics units. As such, the hydrophilicly encased soil is prevented from redepositing on fabrics, in particular hydrophobic fabrics such as polyester, during the laundering cycle.
Ethox~ated Amine Compounds the water-soluble ethoxylzted amine compounds useful in the '~35 present invention area selected from ethoxylated dominoes and ~LZ~3~
.- g o ethoxylated po7yamines, and mixtures thereof as previously de-fined.
In the preceding formulas, Al can be bran hod S ego. -CH2-CH-, -SHEA -), cyclic (e.g. ) or most preferably linear ego. -CH2CH2-9 -CH2-CH2-CH2-, -SHEA OH-) alkaline, hydroxyalkylene~ alkenylene, alkarylene or oxyalkylene. R is preferably C2-C6 alkaline for the ethoxylated I dominoes. For the ethoxylated dominoes, the minimum degree ofethoxylation required for suitable clay soil removal/ant;-redepo-session properties decreases on going from C~-C3 alkaline [ethyl-one, propylene) to hexamethylene. Each R is preferably the moiety -L-X.
In the preceding formulas, hydrophilic chain L usually j consists entirely of the polyoxyalkylene moiety I O)m(CH2CH20)n~- The moieties -trim- and -(Shoeshine- ox the polyoxyalkylene moiety can be mixed together or preferably form blocks of ~~R50)m~ and -(Shoeshine- moieties. R5 is prefer-i ably C3H6 (propylene). For the ethoxylated pylons, m is preferably from 0 to about 5. For all ethoxylated amine compounds of the present invention, m is most preferably n, i.e. the polyoxyalkylene moiety consists entirely of the moiety 2$ -(Shoeshine-. The moiety -(Shoeshine- preferably comprises at least about 85~ by weigh of the polyoxyalkylene moiety and most preferably lox by weight (m is 0).
In the preceding formula, X can be any compatible non ionic group, anionic group or mixture thereof. Suitable non ionic groups include Cluck alkyd or hydroxyalkyl ester or ether groups, preferably acetate and methyl ether, respectivelyi,hydrogen (Ho; or mixtures thereof. The particularly preferred non ionic group is H.
With regard to anionic groups, P03 and S03 are suitable. The particularly preferred anionic group is 503-. It has been found that the percentage of anionic groups relative to non ionic groups can be important to the clay soil removal/anti-redeposition I
- 1 o properties provided by the ethoxylated amine compound. A mixture no from 0 to about 30% anionic groups and from about 70 to 100~
non ionic groups provides preferred properties. A mixture of from about 5 to about 10% anionic groups and from about 90 to about 95 non ionic groups provides the most preferred properties. Usually, ! a mixture from 0 to about 80X anionic groups and from about 20 to 100% non ionic groups provides suitable clay soil removal/anti-re-deposition properties.
Preferred ethoxylated dominoes have the formula:
' 10( ~2cH2o)n-N-cH2~cH2-(cH2)a-N-(cH2cH2o) -x (Shoeshine X (l~H2CH20)n-X
wherein X and n are defined as before, and a is from 0 to 4 (e.g.
ethylene, propylene, hexamethylene). For preferred exulted dominoes, n is at least about 12 with a typical range of from ' 15 about 12 to about 42.
- In the preceding formula for the ethoxylated palominos R3 `' (linear, branched or cyclic) is preferably a substituted C3-C6 alkyd, hydroxyalkyl or aureole group, Jo 20 A is preferably -ON-; n is preferably at least about 12, with a H

The ethoxylated amine compounds of the present invention provide clay soil removal benefits while being anionic detergent surfactant compatible. At most wash oh's, it is believed that the nitrogen atoms of these compounds are partially protonated. The resulting positively charged centers (and remaining polar nitrogen atoms) are believed to aid in the adsorption of the compound onto the negatively charged layers of the clay particle. It is also believed that the hydrophilic ethics units of the compound swell the clay particle so what it loses its cohesive character and is swept away in the wash water.
The anti-redeposition benefits provided by these ethoxylated amine are also believed to by due to the formation of positively charged centers together with the remaining polar nitrogens, in Ills adsorption onto soil suspended in the wash water. As more and more of these compounds adsorb onto the suspended soil, it becomes encased within a hydrophilic layer provided by the attached ethics units. As such, the hydrophilicly encased soil is prevented from redepositing on fabrics, in particular hydrophobic fabrics such as polyester, during the laundering cycle.
