DETER~;ENT COMPOSITIONS

Ramon A. Llenado Field of the Invention This invention relates to surfactant combinations which provide good detergency and, optionally, good fluorescer effectiveness and/or suds control and/or corrosion inhibition in a laundry context. Such compositions can be either built or unbuilt, granular or liquid, and can contain the usual auxiliary ingredients common to such compositions.
Description of the Prior Art Alkylpolyglycosides which are surfactants have been disclosed in U.S. Patents 3,598,865; 3,721,633; and 3,772,269. These patents also disclose processes for making alkylpolyglycoside surfactants and built liquid detergent compositions containing these surfactants. U.S. Patent 3,219,656 discloses alkylmonoglucosides and suggests their utility as foam sta~ilizers for other surfactants. Various polyglycoside surfactant structures and processes for making them are disclosed in U.S. Patents 3,640,998; 3,839,318;
3,314,936; 3,346,55~; 4,011,389, ~,223,129.
Summary of the Invention This invention relates to the discovery of certain ~ombinations o surfactants which provide unusually good detergency, especially in cool water, for a variety of fabric typesO Specifically this invention relates to detergent compositions comprising:
(l? from about 1~ to about 90~ of alkylpolysaccharide detergent surfactant having the formula RO (R ) y (Z) x where R is an alkyl, hydroxy alkyl, alkyl phenyl, alkyl benzyl, or mixtures thereof, said alkyl groups containing from akout 8 to about 18 carbon atoms, where each R' contains from 2 to about 4 carbon a~oms, .. ~. .

L7~ -preferably an ethoxy, propoxy, or cJlyceryl ~roup, and y is from O to about 12; and whare each Z ;s a rno;ety derived from a reclucing saccharide containin~3 5 c>r 6 carbon atoms, and x is a number Fro~ about 1-1- to about 10;
~2~ from about 1O to about 90% of a nonionic deterqent surFactant; and (3) from 0~ to about 90g~ of a deterge~lcy builder, th~ ratio of ~1~ to (2~ being from about 1:10 to about 10:1, pre-ferably from abo-~t 3:1 to about 1:3.
A highly preferred variation also comprises frorn 2bout 0 . 01 to about ~.0~ o~ an anionic fluorescer toptical l~rightener~
In another highly preferred variationr ths nonionic cletergent surFactant is selected from the group consistif~g of ~min~ oxid~
cleterg~nt surfactants, amide detergent surfact3nts and mixtures thereof, and the composition additionally comprise~ fro~ about 1~
to about 10~ of an unsaturated soap containin~ frorn ~bout 16 to about 22 carbon atoms, and, preferatlly, frorn ~Ibout 0% ~o 2bout 10-~ of a synthetic anionic detersent surFact2nt ~0 Description of the Preferred Embodiments The Alkyl?olysaccharide Surfactant I t has surprising!y been found that the cosur~actants inter-act ~ith the ~Ikylpolysaccharide surfactant oF this invention -to provicle good laundry detergency for a ~/idz ran~e o f ~abrics .
The alkylpolysaccharicles are those havin~ a hydrophobic ~3roup containing from about 6 to about 30 carbon atoms, preferably ~ro~n about 10 to about 16 carbon atoms and a polysaccharide, e 9., a polyglycoside, hydrophilic group containin~J from about 1~ to about 10, preferably from about 1~ to about 3, most preferably frorn about 1.6 to about 2.7 saccharide units. ~ny reJ-Jcing sacc~arld~
containing 5 or 6 carbon atoms can be useci f e. c~ cos~, ~alactose and galactosyl moieties can substitute for th~ ~1ucosyl rnoieties. ~Optionally the hydrophobic group is attachec3 ~t l:ne 2, 3, 4 etc. positions thus givincJ a glucose or galactose as o~posed to a cJlucoside or Jalac;oside. ) The intersaccharide bonds can be, e.g., between the one po,ition of the additional saccharide units ~2~ '7~

and the 2-, 3-, 4-, and/or 6 positions on thne precedin~
saccharide units.
Optionally, and less desirably, there can ~e a polyalkox;de chain joining the hydrophobic moiety and the polysaecharide moiety. The preferred alkoxide is ethylene oxic~e. Typical hydrophobic groups include alkyl groups, either saturatecl or unsaturated, branched or unbranched containin~3 From a~out S to about 18, preferably from about 10 to about 16 carbon ~tomsA
Preferably, th~ alkyl group is a straight chain satur~tecl alkyl group. The alkyl group can contain up to 3 hydroxy ~3roups andlor the polyalkoxide chain can contain up to about 10, pref~r-ably less than 5, most preferably 0, aikoxide rnoieties. S~Jita~ie alkyl polysaccharides are octyl, nonyldecyl, unclecyldoclecy~
tridecyl, tetradecyl, pentadecyl, he~cadecyl, heptacl~cyl, anc}
octadecyl, di-, tri-, tetra~, penta-, and hexaglucosides, galactosides, lactosides, ~lucoses, fructosides, fructoses, and~or yalactoses. Suitable mi~ctures inciude coconut alkyl, cli-, tr;-, tetra-, and pentaglucosides and tallow alkyl tetra-, pent~ 3nd hexa~ lucosid~s .
2~ The preferred alkylpolyglycosides have the formula Fi OtCn~l2nO)~t9lycosyl)x wherein F~ is selected from the group consistin~ of alkyl, 21kyl-phenyl, hydroxyalkyl, hydroxyalkylphenyl, and mixtures therevf in ~hich said alliyl gro~ups contain From about 10 to abc~u~ 18, preferably from about 12 to about 14 carbon atorns; n is ~ or 3, preferably 2; t is from 0 to about t0, preferably 0: and x is from 1-' to about 10, pre~erably from about 1~ -to about 3, mos~
preferably from about 1.6 to about 2.7. The glycosyi is pre~erably derived from glucose. To prepare compounds ~h~
alco'nol or alkylpolyethoxy alsohol is formed first and therl reactecl with glucose, or a source of glucose, to ~nrm the gluco~sde (attachment at the l-position). The addition~l ylycosyl units ~re~
attached between their l-position and the precedin~3 ~Iycosyl ~nits 2-, 3-, 4- andlor 6- position, preferably preclominately the 3s 2-position.

Preferably the content of alkylmonoglycoside is lo~t, prefer-ably less than about 60~, more preferably less than about 50~
Surprisingly, anionic fluorescers which are normally rela-tively ineffective in the presence of conventional ethoxylated S nonionic cietergent surfactants at high levels in the al)sence of substantial levels of anionic detergent surfactants, are very ef~ective when the alkylpolyglycoside surf2ctants ~re present.
For brightener effectiveness, the ratio of ~31kylpolyglycosid2 detergent surfactant to nonionic detergent surfactant should b~
10 greater than about 1:4 preferably greater than about 1:3, most preferably greater than about 1:1. .
THE ~ION!ONIC DETERGENT SURFACT~N T
Nonionic Surfactant Nonionic surFactants, including those having an HLa of from 15 about S to about 17, are well l;nown in the detergency art. They are included in the compositions of the present invention togeth~r ~vith the, e.g., alkylpolyglycoside surfactants defined hereinbe-fore. They may be used singly or in combination ~`Jith one or more of the preferred alcohol ethoxylate nonionic surfactants, 20 described below, to form nonionic surfactant mixtures useful in combination with the alkylpolyglycosicl~.s. Examples of such surfactants are listed in U.S. Pat. No. 3,717,630, Booth, issued Feb. 20, 1973, and U.S. Pat. No. 3,332,8~0, Kcssler et al, issued J~lly 25, 1967, 25 Nonlimiting examples of suitable nonionic surfactants ~vhich may be used in the present invention arè as follo~s:

pounds has a molecular weight of from about 1500 to 1800 and cxhibies water insolubility. The addition of polyoxyethylen~
moieties to this hydrophobic portion tends to increase the water solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where ihe polyox~,~ethyl~n~
content is abou~ 50~ of the total weight of the condensatton product, which corresponds to condensation with up to about ~0 35 moles of e~hylene oxideO Examples of compoun~Js o~ this type !

Water-soluble salts of the higher fatty acids t i .e ~, "soaps" are useful anionic surfactants in ~he compositions herein. This includes alkali metal soaps such as the sodium, potassium, ammonium, and alky1olammonium salts of higher fatty acids containing from about 8 to about ~4 carbon atoms, and pre~erably from about . .

~2~J~

12 to about 18 carbon atoms~ Soaps can be made by direct saponification of fa~s and oils or by the neutraiizatior3 of free fatty acids. Particularly useful are the sodium and potassium salts of the mixtures o-f fatty acids derived from coconut oil and taliow, i . e , sodium or potassium tallow and coconut soap~ The pre-ferred soap, as discussed hereinbefore and hereinafter, especially in combination with semipolar or amide nonionic detergent sur-factants, is at least partially lJnsaturated.
The Unsaturated Soap t 0 The unsaturated fatty acid soap of this invention contains from about 16 to about 22 carbon atoms, preferably in a straight chain configuration. Preferably the nurnber of carbon atoms in the unsaturated fatty acid soap is from abollt 16 to abou~ 18.
The unsaturated soap, in common with other anionic deter~
~;ent and other anionic materials in the detergent comp~sitions of this invention, has a cation which renders the soap water-soluble and/or dispersible. Suitable cations include socli--m, potassium, ammonium, monoethanotar~monium, die~hanolamonium, triethanol~
amrnonium, tetramethylammonium, etc. cations. Sodium ions are preferred although in liquid formula;ions ammoniu~, and triethanolammonium cations are useful.
A level of at least about 120 of the ~nsa~uratec~ f~tty acid soap is desirable to provide a noticeable recluction in suclsing and corrosion. Prererred levels of unsaturatecl fatty acid soap are from about 1% to about 15~6, preferably from about 1~ tc~ a~out lû~, most preferably frorl about ~ to about 5O. The unsaturated fatty acid soap is preferably present at a level tha~ tilt provide a level of from about 15 ppm to about 200 ppm, prefera~ly from about 25 ppm to about 125 ppm in the ~vash solution at r~om~
mended U.S. usage levels and from about 30 ppm to a~out loOn ppm, preferably from about 50 ppm to about 50~ pp~n for European usage levels.
~lono-, di-, and triunsaturated fatty acids are all ess~nti~lly equivalent so it is pre'erred to use mostly mon~unsaturat~d soaps to minimize the risk of rancidity. Suitable sources of l.nsaturated , , IL7~

fatty acids are well known. For example, see Bailey's Industrial Oil and Fat Products, Third Edition, Swern, publishecJ by inter-science Publisher ( 1964), Preferably, the levei of saturated soaps is kept as low as s pos~ible, preferably less than about 60~, pre,erably less than about 50~ of the total soap is saturated soap I lowever, lo:Y
levels of saturated soaps can be used. Tallow and palrn otl soaps can be used.

Composition 3 formed an unsightly soap scum in the rinse water despite the presence of rnaterials known to ;nhibit formation oF such scums. Composition 3 also formed a thiclc gel rather than a free flowing, clear liquid. It is clear that there rnust not be a substantial excess of saturated soap over unsatura-tecl. The soap must be at least about 40~ unsaturated soap.
It has additionally been cliscovered that the performance of these compositions is improved if the total fr-ee fatty alcohol containing from about 8 to about 20 carbon atoms is less than about 5~, preferably less than about 2~, most preferably less than about 1~.
