Abstract
ABSTRACT OF DISCLOSURE
The present invention relates to a non-aqueous built liquid detergent composition on the basis of nonionic detergent surfactants and builders. By using particular nonionic detergent surfactants, which contain ethylene oxide and propylene oxide in a molar ratio of 1:17 to 2:1 (propylene oxide to ethylene oxide) instead of the known ethylene oxide condensation products, the rate of dissolution of the composition in the wash liquor is substantially improved.
Furthermore, a low temperature bleach activator such as tetraacetylethylenediamine is substantially much more stable in compositions containing the particular nonionic detergent surfactant than in compositions on the basis of the well-known ethylene oxide type nonionic detergent surfactants.

Description
C 7067 (R) ~289~34 NO~I-AQUEOUS BVILT LIQUID DETERGENT COMPOSITION
The present invention relates to non-aqueou6 built liquid or pasty detergent compositions comprising a non-aqueous liquid medium which contains a nonionic detergent surfactant, and a builder suspended or dispersed in said liquid medium.
Non-aqueous built liquid detergent compositions of this type have already been proposed in the prior art, vide our British Patent Specifications 1 205 711, 1 270 040, and 1 292 352. These prior proposals involve the use of a suspending agent for the builders. More recently, a non-aqueous built liquid detergent composition comprising a liquid nonionic detergent surfactant and being free from dispersants for the solids has been proposed in European Patent Applic;s':ion 0030096.
In all the~e prior proposal~ the nonionic detergent surfactant can be of any type within the class of alkylene oxide condensation products with alcohols, alkylphenols, amides and 80 on.
However, non-aqueous built liquid detergent ~ compositions on the basis of nonionic detergent - surfactants do not always dissolve in an aqueous wash liquor sufficiently quickly, and although the rate of diss~olution can be improved by inclusion of high levels of non-aqueous solvents, that may jeopardize the ; storage stability of the non-aqueous liquid composition and may undesirably increase the costs of such compositions.
It has now been ~found that by using a specific class of nonionic detergent surfactants the rate of dis~olution may be ~ignificantly improved in compari~on with other ~nonionic surfactants, thereby obviating to a , ; ~ : :
' C 7067 (R) 1289~34 significant extent the use of non-aqueous solvents.
The specific class of nonionic detergent surfactants of the invention consists of an organic hydrophobic group, such as C8-C18 alkylphenols, C8-Cl8 primary or secondary, linear or branched-chain alcohols, C8-Cl8 fatty acid amides and so on, which has been condensed first with ethylene oxide (E0) and subse~uently with propylene oxide (P0). The molar ratio of P0 to E0 in the condensation products is critical;
too low a P0/E0 ratio does not offer an advantage, and too high a P0/E0 ratio influences the solubility negatively. The molar ratio of Po to E0 in the nonionic detergent surfactant~ of the invention should lie within the range of 1:17 to 2:1, preferably of 7:4 to 1:2.
The nonionic detergent surfactants of the in~n~ion ~hould furthermore not form high v~scosity liquid crystalline phases in the presence of water, ahd should have cloud points of above 5C. Suitable examples of nonionic detergent surfactants of the invention are C13-C15 primary alcohol, condensed with 7 moles of ethylene oxide and 4 moles of propylene oxide and C13-C15 alcohol, condensed with 4.9 moles of ethyler~e oxide and 2.7 moles of propylene oxide.
Preferably, the nonionic detergent surfactant~ of the ;~ invention are low-foaming.
Mixtures of nonionic detergent 6urfactants of the invention with other detergent surfactant~, such as anionic, cationic or ampholytic detergent surfactants, and soaps may also be used. If such mixtures are used, the mixture must be water-free and liquid at room temperature.
::
;~ Examples of suitable anionic detergent surfactants are 12894~4 C 7067 (R) alkali metal, ammonium or alkylolamine salts of alkylbenzene sulphonates having from 10 to 18 carbon atoms in the alkyl group, alkyl and alkylether sulphates having from 10 to 24 carbon atoms in the alkyl group and from 1 to 5 ethylene oxide groups, olefin sulphonates prepared by sulphonation of C10-C24-olefins and subsequent neutralisation and hydrolysis of the sulphonation reaction product.
Examples of cationic detergent surfactants are aliphatic or aromatic higher alkyl di(lower alkyl) ammonium halides and examples of soaps are the alXali metal salts of C12-C24 fatty acids-In general, the composition of the invention contains the nonionic detergent surfactant in an amount of atleast 10~ by weight of the total composition. The amount of nonionic detergent surfactant present in the compo~ition may be as high as about 90%, but in mo8t cases the practical amount will lie between 20 and 70%
and preferably between 20 and 50% by weight of the composition.
The builder which i8 used according to the present invention may be either a preferably anhydrous inorganic builder or an organic builder. Suitable organic builders are the alkali metal salts of aminopolycarboxylic acids, such as ethylene diaminetetraacetic acid (EDTA), nitrilotriacetic acid ~; (NT ), diethylenetriamine pentacetic acid (DEPTA), hydroxythylaminodiacetic acid and the like; alkali metal salts of ethane hydroxyphosphonic acids, aminophosphonic acids and the like: polyelectrolytes such as alkali metal salts of hydrolysed copolymers of ethylene with maleic anhydride and alkali metal polyacrylates; alkali metal alkenylsuccinates and the like, and sodium phytate. Suitablè inorganic builder ~re zeol1t-~, the alkal1ne ortho-, poly-, pyro- and , 1289434 C 7067 (R) metaphosphates, Rilicates, borates, carbonates and the like. Also mixtures of organic and inorganic builders may be used. The organic builders need not be anhydrous, but can be used in the hydrated form in which they are normally fiold, for example NTA lH20, EDTA 2H20 and 50 on.
The amount of builder present in the composition may be from 1 to 70% by weight of the composition. For most commercial purposes the amount of builder is from about 10% to about 60% by weight of the composition. The builder should have a particle size of less than 300/u, preferably less than 200/u.
m e weight ratio of the nonionic detergent surfactant to builder should generally lie within the range of 10:1 and 1:4, and for most commercial purposes within the range of 4:1 to ls4, the preerred ratio being about ls2.
The liquid detergent composition of the invention is substantially anhydrous, by which is to be understood that the final composition should contain not more than 5%, and preferably less than 2% by weight of water;
this does not include any water of hydration.
The stability behaviour of the products may be further improved by the incorporation of a few per cent of an 9~ emul~-lfier or a thixotropic agent, such as lauric 30-~ diethanolamide,~ ethoxylated lanolin, sodium dioctyl sulphosuccinate and the like.
The viscosity of the composition will vary, depending upon its ConJtituent~. In order to ensure that the composition may be poured satisfactorily, it is preferred that~the viscosity ~houid be in the range of from 100 to 3,000 cP, although higher viscosities up to .:
.
.: . : . . ~, ::
1289434 C 7067 (R) 60,000 cP can be satisfactory. If desired, the viscosity of the composition may be adjusted by the addition of amounts of up to 20~ of a thinning agent, for example ethyl alcohol, hexane, heptane, benzene, xylene, toluene, tetrahydrofuran, dimethyl sulphoxide, and the like.
The composition may furthermore contain other materials which are considered normal and desirable additives in detergent compositions. For instance, bleaching agents such as alkali metal perborates (either anhydrous or in one of their hydrate forms) may be incorporated in an amount of from about 5 to about 30% by weight of the composition. Without substantially modifying the fundamental characteristi~s of the compositions of the invent$on, there can furthermore be incorporated enzymes, such as amylases and proteases, lipases, colouring agents, fluorescers, bleaching agent precursor~ and activators, bleach ~tabil~zers, perfumes, bactericides, soil suspending agents and corrosion-inhibitors.
In this respect, it has surprisingly been found that bleach precursors such as tetraacetylethylene diamine are more stable in the non-aqueous detergent compositions of the present invention than in non-aqueous liquid detergent compositions on the basis of ' nonionic detergents other than those according to the invention.
Optionally, suspending agents such as highly voluminous metal oxide~ and metalloid oxides such as silica may also be included in an amount of 1-5% by weight.
The invention is illustrated by the following Examples in which tbe~ percentages are by weight.

The rates of solution of the composition were measured by adding the non-aqueous liquid detergent at a concentration of6.5 9/1 to tapwater of room temperature under constant stirring (100 rpm) and measuring the conductivity of the resulting mixture. The time at which the conductivity does not change anymore i6 recorded as the dissolution time.
