COMPOSITIONS
The following statement is a full description of this invention including the best method of performing it known to me:- .d1v-7 1 r

EXAMPLE 2 ^3 8984E FABRIC PRETREATMENT CLEANING COMPOSITIONS BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to pretreatment compositions for the cleaning of fabrics, especially aerosol mousse and liquid 00oo S’ spray type products.
o 0 0o s o 00 0 00 2. The Prior Art ao o o 0 0 o 0° 0* The present invention is concerned with laundry pretreater compositions in either aerosol mousse or liquid spray S form. Both of these forms require formulation of homogeneous a o e compositions.
S. .Laundry pretreaters or prespotters are designed to aid in the removal of recalcitrant stains. They are used neat on the I stain prior to the garment being washed in a machine with laundry i 5, detergent and other additives. Particularly recalcitrant stains are those of grease and oil, ground-in dirt (clay), blood and t other proteinaceous stains such as those caused by grass.
Aerosol products of every description, and most recently aerosol mousses discharged by inverting, are very popular in the 1 discharge of an unhomogeneous dosage may result in poor product performance, even unsafe performance due to imbalance of composition ingredients.
Likewise, during manufacture, compositions that are not homogeneous would have to be kept so with constant stirring and S. circulation of ingredients during container filling operation.
S dor” Without homogeneity, the aerosol unit could not be dosed with the 0 00 00 correct unit amount of ingredients. Precautions to insure homo- 0 0 0 0 geneity are quite burdensome. Thus, there is a need for stable o dU.S. Patent 4,652,389 (Moll) describes a foaming aerosol composition for the cleaning of carpet. Primary components include a solvent with consistent evaporation rate, a surfactant, o*00 and a propellant, all in an aqueous system. Solvent and surfactant admixture interact with the propellant to form an initial 00-00 foam upon dispensing. The foam then collapses into the carpet followed by a secondary re-foaming.
An aqueous laundry prespotting composition is described in U.S. Patent 4,595,527 (Gipp) which reports achieving satisfactory oily stain removal in an essentially organic s lvent free -2media. Evidently crucial to the success of this prespotter is the presence of a chelating agent such as ethylenediaminetetraacetic acid or citric acid salts and at least one nonionic solvent such that total surfactant HLB ranges from 9 to 13. Surfactant mixtures are suggested which include Neodol 25-7® and Neodol 25-3@ identified as C 12
-C
1 5 linear alcohol ethoxylates with, respectively, 7 and 3 moles ethylene oxide per alcohol unit.
04 01 0 0 o Prespotting compositions are disclosed in U.S. Patent 4,438,009 (Brusky et al.) which were said to exhibit special Q ro 0 a00 Seffectiveness against both oil and water-borne stains while util- 00 0 0 0 0 o. izing a relatively low percentage of solvent. Success of this 0 0 0 0 0 composition was attributed to a surfactant mixture of sorbitan fatty acid, ethoxylated nonylphenol or alcohol, and ethoxylated 15o. sorbitan fatty acid. Total HLB of the surfactant combination 0 o0 0 00 must range between 8.5 and 10.5.
0600 oo U.S. Patent 4,530,781 (Gipp) reports metastable prespotting compositions comprising a chelating agent, an organic 0 C Ssolvent, at least one nonionic surfactant, and water. The formulation typically forms at least two phases which are readily redispersed by shaking to provide a metastable composition.
Example 1 lists a combination of four surfactants including sorbitan monooleate, ethoxylated sorbitan monooleate, nonylphenol -thoxylate (6 moles EO) and nonylphenol ethoxylate (3.5 moles -3- EO). An isoparaffinic hydrocarbon, EDTA, citric acid, and water round out the formulation.
Evident from the aforecited art is that considerable technology is available with respect to laundry prespotting and pretreatment. Nevertheless, it is also evident that the known formulations have not been optimized for use with aerosol mousse and spray liquid type products.
Accordingly, it is an object of the present invention to 0 .o provide an aerosol mousse or spray liquid cleaning composition 0 00 for the pretreatment of fabric which has superior soil removal 0 properties for a wide variety of stains.
I Another object of the present invention is to provide a laundry pretreater composition containing both water and hydrocarbon solvent which components form into a clear homogeneous liquid that allows for uniform dosing in manufacturing and dispensing.
A still further object of the present invention is to provide an aerosol mousse type product that upon discharge forms a foam that alternately in repeating series peaks (expands) and 11 20 collapses before foam dissipation.
These and other objects of the present invention will become more apparent from the following more detailed description.

An aqueous, clear homogeneous liquid is disclosed comprising: from 1 to 20% of a mixture of non-soap surfactants comprising: a first ethoxylated nonionic surfactant having an HLB less than and (ii) a second ethoxylated nonionic surfactant having an HLB greater than the ratio of to (ii) being 3:1 to 1:3; from 1 to 30% of a hydrocarbon solvent chosen from the group consisting of kerosene, solvent naphtha, terpenes and chlorinated hydrocarbons and mixtures of any two or more thereof; and from 1 to 20% of a salt of a C 12
-C
22 fatty acid, said composition having a pH from to Lii r Other components useful in the formulation include chelating agents such as EDTA and coupling agents such as isopropanol and sodium xylene sulfonate. “Dancing” foam may best be achieved by having a propellant in an amount at least 20% by weight of the total composition. A particularly preferred fatty acid salt is that of triethanolamine oleate formed from triethanolamine and oleic fatty acids.
DETAILED DESCRIPTION OF THE INVENTION Compositions of this invention which must compatibilize water and hydrophobic solvent were found to require a special combination of nonionic surfactant. The combination must include a pair of ethoxylated nonionic detergent actives. The first of these actives must have an HLB of less than 10, preferably less than 8. Illustrative of the first type nonionic are alkoxylated

1 2 alkyl phenols.
Especially preferred are C 12
-C
15 fatty alcohols ethoxylated with an average 3 moles ethylene oxide (EO) such as in Neodol 25-3@.
0* S. A second type nonionic detergent active required for the S° composition is one which has an HLB of greater than 10, preferably at least 13. Illustrative of the second type detergent ooo active are higher alkoxylated C9-C 18 alkyl fatty alcohol and lower alkoxylated C 6
-C
12 alkyl phenol. Especially preferred within this category are C 12
-C
1 5 alcohol ethoxylated with an average 9 moles ethylene oxide (EO) such as Neodol 25-98.
Amount of first to second ethoxylated nonionic surfactant will range in a ratfo from about 3:1 to 1.3, preferably 2:1 to 1:2, optimally 1:1.
The compositions of this invention are intended to be effective against both hydrophilic and hydrophobic stains. As a consequence, the formulation will contain water as a carrier for the hydrophilic and hydrocarbon solvent as a carrier for the hydrophobic stains. Water may range in an amount from 10 up to preferably between 15 and 50%, optimally between 20 and The hydrocarbon solvent may be present from about 1 to 30%, preferably from 5 to 20%, optimally around Hydrocarbon solvent is considered to be any hydrophobic organic liquid having at least moderate volatility. Within this category may be included such hydrocarbon solvents as deodorized kerosene, solvent naphtha, terpenes and chlorinated hydrocarbons.
1 0 Within the kerosene and solvent naphtha category there may be Sincluded paraffins, naphthenes, aromatics, olefins and isoparaffins. Chlorinated solvents include 1,l,l-trichloroethane, perchloroethylene and methylene chloride.
Particularly preferred are the hydrocarbon solvents sucA as 50, Shellsol 71® and Shell 460 Solvent®.

2 2 fatty acid, i.e. soap, is a further important component. Sodium soap may be utilized but the amine type soaps have been found to have special advantage. This comoaooo ponent aids in stain removal and helps achieve homogeneity. More than this, however, the soap forms a film around the propellant of the composition entrapping propellant and thereby assisting in the foam delay. Particularly effective are the ammonium and alkanolammonium, including the triethanolammonium, salt of
C

-C
22 fatty acid. Oleic fatty acids are preferred. Most effective has been found to be the triethanolammonium salt of oliic acid which combination can be formed in situ from triethanolamine and free oleic acid present in equimolar proportion.
Soap will be present in the composition in an amount I OACoAo-4, from about to 1% preferably from about 2 to optimally around 3%.
Coupling agents are also desirably present in the formulation. Amounts of these agents may range from about 1% to 20%, preferably from 8% to 20%, optimally around 15%. As the name implies, the coupling agent helps to compatibilize various j components of the composition. Suitable materials for this purpose are C 1
-C
4 alkanols and sodium C 1
-C
3 alkyl phenol sulfonate salts. Examples of these materials are ethanol, isopropanol, sodium xylene sulfonate and sodium toluene sulfonate. The Ssulfonates also aid in low temperature stability connected with the freeze-thaw cycles. Isopropanol also performs the dual function of being a foam depressant.
Builders, especially those of the chelating variety, may be employed with formulations of the invention. Examples of such builders include sodium ethylenediaminetetraacetate (EDTA) available as Trilon BO, sodium citrate, and phosphonic acid derivatives such as the Dequest® products. Builder will normally -8-
I
i be present in amounts ranging from 0.5 to 10%, preferably from 1 to optimally around 3%.
Enzymes may also be included in the compositions. These enzymes may include proteases, amylases, lipases, cellulases and combinations thereof. When present, the enzymes will range in i amount from about 0.005 to about preferably from about 0.1 to optimally around Normally, the presence of enzymes also requires the presence of stabilizing agents. Among such agents I are hydrated sodium borate and/or propylene glycol. These stabilizers will be present in amounts anywhere from 0.1% up to i preferably from 1% to 15%, optimally around S Aerosol mousse compositions of this invention will also require the presence of a propellant to deliver and build the Ij first foam. Although not limited to, the propellant usually is a
C

-C
10 hydrocarbon such as methane, ethane, n-propane, n-butane, ii isobutane, n-pentane or isopentane and mixtures thereof.
Halogenated hydrocarbons may also be utilized but these are not preferred because of environmental problems. The amount of pro- Spellant relative to the combined other ingredients will range from about 4:1 to 1:4, preferably about 2:1 to 1:1, optimally about 3:2. Where the aerosol mousse is required to “dance” having alternate foam expansion and collapse, it is necessary to have a minimum of 20% and maximum of 80% propellant by weight of the total composition.
-9- Other important aspects of the invention include the pH which normally should range from about 7.5 up to 10, preferably between 8.5 and 9.5, optimally about The following examples will more fully illustrate the embodiments of this invention. All parts, percentages and proportions referred to herein and in the appended claims are by weight unless otherwise illustrated.

Without Shellsol 71@, it is sufficient to have a single surfactant, i.e. Neodol 25-9®, to achieve homogeneity as shown in Formulation 6. Of course, not all surfactants even in the absence of a solvent will lead to homogeneous solutions. See Formulation No. 9 with Neodol 91-2.5@ where separation was observed.
