Abstract
ABSTRACT OF THE DISCLOSURE Novel liquid hard surface cleaning compositions are provided in the form of a homogeneous aqueous solution which comprises a glycoside surfactant, a water miscible organic solvent, a water soluble detergent builder and water and which effectively cleans soiled hard surfaces without rinsing and without leaving an objectionable residual film on such surfaces after clean-ing.
Description
~L~
BACKGROUND OF THE INVENTION
The present invention relates to aqueous liquid detergent compositions and to the use of same for the cleansing of soiled hard surfaces such as appliance cabinets or housings, wal Is, windows and the I ike .
Alkyl glycoside materials such as, for example, higher alkyl monoglycosides and higher alkyl polyglycosides are known materials; are known, at least in certain circumstances, to function as nonionic surfactants; and have been suggested as being suitable for use in certain specially formulated detergent composi-tions. See in this regard, for example, Published European Patent Application Numbers 0070074; 0070075;
0070076; and 0070077, all of which published on January 19, 1983 as well as Published European Patent Applica-tion Numbers 0075994; 0075995; and 0075996 which pub-lished on April 6, 1983.
A relatively specialized category of cleaning composition of interest to the art is one which is often referred to as a liquid detergent hard surface cleaning composition and which is specifically designed or for-mulated such that it can be applied to a soiled hard surface of interest (e.g., glass, painted walls, woodwork, etc . ) and removed therefrom ( for example as by wiping with a dry or damp cloth) without a subse-quent rinsing operation and without leaving a significant or unsightly residual film upon the surface after clean-ing. Thus, for example, in Published South African Patent Application No. 666,781 there is described a hard surface cleaner composition which comprises from 1 -10%
of an anionic surfactant (e.g., alkyl sulfate or alkyl aryl ~, ...
sulphonate~ or a nonionic surfactant (e.g., an ethylene oxide condensate of a fatty alcohol or of an alkyl phenol) and at least 20~ of a 1:1 to 4:1 ratio mixture of an alkali metal (or ammonium) borate and sodium carbonate and which, at a 1% concentration in water, has a pH of at least 9 . 6 .
On the other hand, U. S. Patent 3,591,510 to 10 William Edward Zenk (issued July 6, 1971) describes certain liquid hard surface cleaning compositions consist-ing essentially of from about 0. 25 to 4~ of certain select-ed anionic or zwitterionic detergents; from about 0. 5 to about 63 of certain water soluble builder components;
15 from about 1 to about 10% of certain selected organic solvents or solvent mixtures; and the balance being water .
In a recent journal article, namely "A Greasy Soil Hard Surface Cleaning Test" by Morris A. Johnson, 20 JAOCS, Vol. 61, No. 4, pages 810-813 (April 1984), a series of commercially available solvent-based and water-based cleaners were tested for greasy soil removal ef~ectiveness at various dilution ratios.
Hard surface cleaning formulations are also 25 discussed in "Formulation of Hard Surface Spray Clean-ers" by R. E. Johnson and E. T. Clayton, detergents and specialties, June 1969, pages 28-32 and 56. Formu-lations discussed in such article included ~a) one which was composed of 1 weight percent of a nonionic 30 surfactant (linear alcohol ethoxylate), 2. 5 weight percent of anhydrous tetrapotassium pyrophosphate ~builder), 5 weight percent of ethylene glycol monobutyl ether (solvent) and the balance water and (b) another which 39~
was the same as the former except that the indicated nonionic surfactant was replaced with a corresponding 5 amount of a linear alkylbenzenesulfonate anionic surfactant. In said article it is noted that the afore-mentioned nonionic surfactant-based formulation exhibited slightly more filming li.e. being given a "moderate" film rating) than its corresponding anionic surfactant-based 10 counter-part (which obtained a "moderate-good" film rating ) .

SUMMARY OF THE INVENTION
It has now been discovered that the use of nonionic glycoside surfactants in certain hard surface liquid cleaning compositions provides compositions which have excellent cleaning characteristics and which also have an unexpectedly and/or surprisingly low propensity to deposit or leave an undesirable residual film upon hard surfaces cleaned therewith, even in the absence of a separate rinsing step or operation. Accordingly, the present invention, in one of its aspects, is a liquid detergent composition which comprises:
(a) a nonionic surfactant component, at least about 10 ( preferably at least about 25, more preferably at least about 50 and more preferably still at least about 75) weight percent of wh;ch (on a total nonionic surfactant component weight basis) is a glycoside surfactant, said nonionic surfactant component typically constituting from about 0.1 to about 50 weight percent of the total weight of said detergent composition;
(b) a water miscible organic solvent, typically in an amount of from about 0.1 to about 50 weight percent on a total detergent composition weight basis;
(c) a water soluble detergent builder, typically in an amount of from about 0.1 to about 50 weight percent on a total detergent composition weight basis; and ~2~
(d) water, typically in the range of from about 10 to about 99 . 7 weight percent on a total deter-gent composition weight basis~
The detergent composition of the present invention can, if desired, suitably take the form of a dilutable liquid concentrate for the purposes of its 10 convenient and economical initial manufacturing or formu-lation operations, transport or distribution, and/or marketing and can then be subsequently diluted (e. g ., by the final distributor or the ultimate user) with water prior to its ultimate use for hard surface cleaning pur-1 5 poses.
In their aforementioned concentrated form, thecompositions of the present invention will typically comprise, on a total concentrate composition weight basis:
a. from about 5 to about 50 (preferably from about 5 to about 30) weight percent of the aforementioned nonionic surfactant component;
b. from about 10 to about 50 ( preferably from about 10 to about 30) weight percent of the water miscible organic solvent;
c. from about 10 to about 50 (preferably from about 10 to about 30) weight percent of the water soluble detergent builder; and d. from about 10 to about 75 ( preferably from about 20 to about 60 and most preferably from about 30 or 40 to about 50 or 55) weight percent water.
7~39~
On the other hand, the compositions of the present invention in their diluted for ultimate hand 5 surface cleaning purpose form will typically comprise, on a total diluted composition weight basis:
a. from about 0.1 to about 10 (preferably from about 1 to about 5) weight percent of the above-identified nonionic surfactant component:
b. from about 0.1 to about 10 ( preferably from about 1 to about 5~ weight percent of said water miscible organic solvent;
c. from about 0.1 to about 10 (preferably from about 1 to about 5) weight percent of said Y~ater soluble detergent builder; and d. from about 60 to about 99.7 (preferably from about 60 to about 97 ) weight percent w ater .
In another of its broad aspects, the present 20 invention is also represented by a method for cleaning a soiled hard surface by the application thereto and lhe subsequent removal therefrom of an effective amount of the above-described, diluted-form hard surface cleaning composition of the instant invention.

_ETAILED DESCIRIPTION OF THE INVENTION
Glycoside surfactants suitable for use as a 5 significant proportion (e.g. at least about 10 weight percent, preferably at least about 25 weight percent, more preferably at least about 50 weight percent, even more preferably at least about 75 weight percent and most preferably constituting essentially all) of the 10 nonionic surfactant component of the present invention include those of the formula:
R0(R'0)y (Z)x wherein R is a monovalent organic radical (e. g ., a monovalent saturated aliphatic, unsaturated aliphatic or 15 aromatic radical such as alkyl, hydroxyalkyl, alkenyl, hydroxyalkenyl aryl, alkylaryl, hydroxyalkylaryl, arylalkyl, alkenylaryl, arylalkenyl, etc. ) containing from about 6 to about 30 ( preferably from about 8 to about 18 and more preferably from about 9 to about 13) carbon 20 atoms; R' is a divalent hydrocarbon radical containing from 2 lo about 4 carbon atoms such as ethylene, propylene or butylene (most preferably, the unit (R'O)y represents repeating units of ethylene oxide, propylene oxide and/or random or block combinations thereof); y is 25 a number having an average value of from 0 to about 1~;
Z represents a moiety derived from a reducing saccharide containing 5 or 6 carbon atoms (most preferably a glucose unit); and x is a number having an average value of from 1 to about 10 ( most preferably ~`~ 30 from 1 to about 3).
Glycoside surfactants of the sort mentioned above, and various preferred subgenera thereof, are fully discussed in U. S. Patent 4,483,779 to Llenado et , ~Z~ 37~L
al. (issued November 20, 1984), Nonionic glycoside surfactants of particular interest for use in the practice of the present invention preferably have a hydrophilic-lipophilic balance (HLB) in the range of from about 10 to about 18 and most prefer-10 ably in the range of from about 12 to about 14.
As is implied above, conventional nonionicsurfactants different from the above-described glycoside type can, if desired, optionally be employed in conjunc-tion with (i.e., as a nonionic cosurfactant with) the 15 aforementioned glycoside surfactants so long as the amount of such nonionic cosurfactant is controlled to a sufficiently low level so as to avoid causing the resulting formulation to have an unacceptable propensity to leave a visually detectable (or unacceptable) residual film follow-20 ing the use of same, in diluted form, in hard surfacecleaning applications. Surprisingly, it has been found that even conventional nonionic cosurfactants which by themselves have an unacceptably high propensity to leave a visually unacceptable residual fil~n when used as ~5 the sole nonionic surfactant in hard surface cleaning compositions can, when used in conjunction with glycoside surfactants in accordance with the present invention, constitute as much as about 90 weight percent (preferably about 75 percent or less and most preferably 30 about 50 percent or less) of the total weight of the nonionic surfactant component without imparting unacceptably high residual film-forming properties to the resulting hard surface cleaning composition of interest.

As a general rule, however, it will typically be convenient to first admix the water arld the water miscible organic solvent together and to thereafter add thereto (and dissolve therein) the re-mainder of the ingredients to be employed within the subject liquid hard surface cleaning composition.
As has been noted above, the hard surface cleaning compositions of the present invention, if desired, can suitably be initially formulated, trans-ported, distributed and/or marketed in the forrn of a dilutable aqueous concentrate composition and, in such event, can be diluted to the ultimately desired, end-use active ingredient strength by the eventual end-user or by a distributor at the retail or wholesale level. Alter-natively, the liquid hard surface cleaning compositions hereof can also suitably be initially and directly manu-factured or formulated, transported, rnarketed and used or consumed in its pre-diluted, ready-to-use form as previously described in accordance with the present invention .

The above-described hard surface cleaning compositions proYide efficient and effective cleaning of S soiled hard surfaces (such as, for example, glass, painted walls, stove tops, woodwork, ceramic tile, appli-ance housings, etc. ) without rinsing and without leaving an objectionable residuai film upon such surfaces after cleaning .
In evaluating the relative cleaning effective-ness of the subject cleaning compositions, it is conven-ient to employ a Gard~r Washability Apparatus (using a standard soil tile and at standard pressure and sponge stroke settings), to determine or quantify the cleaning 15 efficiency of a given cleaning composition of interest. In determining the cleaning efficiency, reflectance values are determined using a Gardner Lab Scan Reflectometer for each of the following: a clean unsoiled panel, a soiled panel and a soiled panel following Gardner 20 Washability Apparatus scrubbing. Such reflectance values are then employed to calculate % cleaning efti-ciency according to the following formula:
% cleaning efficiency = Rw - Rs 1 OOg6 Ro - Rs wherein:
Rw = Reflectance of the washed tile or panel Rs = Reflectance of the soiled tile or panel and Ro = Reflectance of the clean, unsoiled tile or panel.
The propensity of a given hard surface clean-ing composition of interest to leave an undesired residual film upon a surface following cleaning ~i.e., spray on -~i7~39~
wipe off with no rinsing ) therewith is conveniently determined by applying 10 drops of the cleaning formu-5 lation of interest upon the surface of a 4" x 4" blackceramic tile wiping dry using 20 strokes with an adsorbent paper towel; and measuring the gloss of the ti le surface using a Glossgard 11 Glossmeter. The gloss reading of the black tile surface is determined both 10 before and after application (and wiping off) of the cleaning formulation of interest. The difference in gloss reading as between the before treatment reading and the after treatment reading is determined and is recorded as "~ Gloss Reduction".
Filming propensity of various cleaning formu-lations of interest can also be evaluated visually by visually inspecting the aforementioned black ceramic tile following app1ication thereto (and removal or wiping therefrom) of the cleaning formulation and visually 20 categorizing the degree of filming propensity as either "heavy", "moderate", "light", "trace" or "no filming" or as being at borderline locations in between two of the aforestated categories.
The present invention is further illustrated 25 and understood by reference to the following examples thereof in which al I parts and percentages are on a weight basis unless otherwise indicated.
