Abstract

THE RATE OF SOLUTION OF A SUBSTANTIALLY NON-AQUEOUS, BUILT LIQUID DETERGENT COMPOSITIONS COMPRISING A WATER-FREE LIQUID DETERGENT SURFACTANT, AN INORGANIC CARRIER MATERIAL AND A BUILDER IS IMPROVED BY THE INCORPORATION THEREIN OF A SMALL AMOUNT OF AN ACID SUBSTANCE.

Description

United States Patent Int. or. (31111 3/075, 7/42 US. Cl. 252l36 7 Claims ABSTRACT OF THE DISCLOSURE The rate of solution of a substantially non-aqueous, built liquid detergent composition comprising a water-free liquid detergent surfactant, an inorganic carrier material and a builder is improved by the incorporation therein of a small amount of an acid substance.

BACKGROUND OF THE INVENTION Field of the invention The present invention relates to a built liquid detergent composition. More particularly, it relates to a readily water-soluble or dispersible, substantially non-aqueous built liquid detergent composition that contains a small, effective amount of an acid substance.

Description of the prior art Aqueous built liquid detergent compositions are wellknown in the art. They are either water-based or contain a mixture of water and alcohol. These compositions typically contain a relatively small percentage of a detergent surfactant. According to the prior art, it is difficult to include a very high proportion of a detergent surfactant without considerably impairing the desired physical properties of these liquid compositions. These compositions either contain a considerable proportion of water or they suffer from manufacturing difficulties, eg the need for collodial builder and a hydrotrope. Because of the high water content of aqueous built liquid detergent compositions, which increases their transport and storage costs, their use is uneconomical. The packaging costs are particularly high in relation to the content of active ingredients, when the products contain much water.

It has already been proposed in Dutch patent application 6,801,099 to produce a substantially non-aqueous stable built liquid detergent composition which allows the incorporation of large percentages of inorganic builder salts and detergent surfactants. According to this proposal, the substantialy non-aqueous built liquid detergent composition contains as essential ingredients a liquid detergent active, an inorganic carrier material and an anhydrous inorganic builder salt.

Although these non-aqueous built liquid detergent compositions do not show the disadvantages inherent in aqueous built liquid detergent compositions as described before, the rate of solution or dispersion of these non-aqueous built liquid detergent compositions in water is often not the optimum for practical purposes.

As described in the co-pending application Ser. No. 3,192, filed Jan. 15, 1970, a substantially non-aqueous built liquid detergent composition that essentially contains a liquid detergent surfactant, an inorganic carrier material and an organic builder has an improved rate of solution in comparison with that of such a composition containing an anhydrous inorganic builder salt.

SUMMARY OF THE INVENTION It has now been found surprisingly that the rate of solution or dispersion in water of a substantially non- See aqueous built liquid detergent composition that comprises a substantially water-free liquid detergent surfactant, an inorganic carrier material and a builder can be significantly improved by the addition thereto of a small, effective amount of an acid substance.

The present invention therefore provides a substantially non-aqueous built liquid detergent composition with an improved rate of solution or dispersion in water, said composition comprising a substantially water-free liquid detergent surfactant, an inorganic carrier material and a builder, wherein the improvement comprises the incorporation therein of a small, effective amount of an acid substance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The acid substance which is used according to the present invention may be any organic and/or inorganic substance, which acts as a proton-donor in the compositions of the invention. Examples of suitable acid substances are inorganic acids, such as hydrochloric, carbonic, sulphurous and phosphoric acids; inorganic acid salts, such as potassium monohydrogen sulphate, potassium monohydrogen phosphate, potassium dihydrogen phosphate, sodium monohydrogen phosphate, potassium dihydrogen pyrophosphate, tetrasodium monohydrogen triphosphate; organic acids such as formic, acetic, propionic acid, trichloroacetic acid, succinic, lactic, citric, amino acetic, benzoic, salicylic, phthalic, nicotinic, ascorbic and nitri'lotriacetic acids; organic acid salts such as disodiumethylenediaminetetraacetic acid can also be used. Furthermore, acid anhydrides such as acetic acid anhydride, phthalic acid anhydride, succinic acid anhydride can be used.

The amount in which the acid substance is used must be such that the physical characteristics of the composition are not significantly altered.

In general, the amount will be in the range of from 0.025 to about 3% by weight of the final composition. The concentration of the acid substance must be such that the composition remains substantially anhydrous as hereinafter defined.

The liquid detergent surfactant which is used according to the present invention must be liquid at room temperature and must be substantially free from water. If necessary, the liquidity of the detergent surfactant may be adjusted with an organic thinning agent, such as ethyl alcohol and the like. The lower the viscosity of the liquid detergent is, the more suitable it is in compositions of the invention. Any liquid detergent surfactant may be used. Suitable liquid detergent surfactants are nonionic detergent surfactants that are liquid at room temperature.

Nonionic detergent surfactants are well-known in the art. They normally consist of a water-solubilizing polyoxyalkylene group in chemical combination with an organic hydrophobic group derived, for example, from alkylphenols in which the alkyl group contains from about 6 to about 12 carbon atoms, dialkylphenols in which each alkyl group contains from 6 to 12 carbon atoms, primary, secondary or tertiary aliphatic alcohols having from 8 to 20 carbon atoms, monocarboxylic acids having from 10 to about 24 carbon atoms in the alkyl group, polyoxypropylene, fatty acid monoand dialkylol amides in which the alkyl group of the fatty acid radical contains from 10 to about 20 carbon atoms and the alkylol group is a lower alkylol group having from 1 to 3 carbon atoms, and ethoxylated derivatives thereof, e.g. tallow fatty acid amide condensed with 20 moles of ethylene oxide.

The nonionic detergent surfactant should have a molecular weight of from about 300 to about 11,000.

Mixtures of different nonionic detergent surfactants may also be used, provided the mixture is iiquid at room temperature. Mixtures of nonionic detergent surfactants with other detergent surfactants such as anionic. cationic, ampholytic detergent surfactants and soaps may also be used. If such mixtures are used, the mixture must be liquid at room temperature.

Examples of suitable anionic detergent surfactants are alkali metal, ammonium or alkylolamine salts of alkylbenzene sulfonates having from 10 to 18 carbon atoms in the alkyl group, alkyl and alkylether sulfates having from 1024 carbon atoms in the alkyl group and from 1-5 ethylene oxide groups, olefin sulfonates prepared by sulfonation of C C a-olefins and subsequent neutralization and hydrolysis of the sulfonation reaction product. Examples of cationic detergent surfactants are aliphatic or aromatic higher alkyl-ditlower alkyl)-ammonium halides and examples of soaps are the alkali metal saltS of (E -C fatty acids.

In general, the composition of the invention contains the substantially Water-free liquid detergent surfactant in an amount of at least 10% by Weight of the total composition. The amount of liquid detergent surfactant present in the composition may be as high as about 90%. but in most cases the practical amount will lie between 30 and 70%, and preferably between 20 and 50% by weight of the composition.

The inorganic carrier material which is used according to the invention should have a particle size of l-l m./ an average surface of 50800 m. /g.as measured by the B.E.T. (Brenauer, Emmett and Teller) method-and a bulk density of from to 180 g./l.

Suitable inorganic carrier materials are light. highly voluminous metal oxides and metalloid oxides such as silica, alumina, magnesia. ferric oxide. titanium oxide and the like. Mixtures of highly voluminous metal oxides and metalloid oxides, for example a mixture of silica and alumina, may also be used. Suitable highly voluminous inorganic carrier materials, particularly silicas. may readily be obtained commercially. They are sold. for instance, under the registered trade names Aerosil and Cab- O-Sil.

Whilst any highly voluminous inorganic carrier material having the specified physical characteristics may be employed in the composition of the invention, it is preferred that the carrier material should have a bulk density within the range of from to 150 g./'l.. more particularly from to 100 g./l., and an average surface area lying within the range of from 150 to 400 mfi/g. The particle size of the inorganic carrier material should be from 1 to 100 m./ by which is meant that substantially all of the particles of the carrier material should lie within the specified range.

The amount of the inorganic carrier material which is used may be from 0.l10% and is preferably in the order of from 1 to 5% by weight of the composition.

The builder which is used according to the present invention may be either an inorganic or an organic builder. A builder is an alkaline salt which complexes the ions of hard water and which increases the level of detergency attainable with a detergent surfactant. The benefit of the invention is obtained with inorganic as well as with organic builders. Suitable organic builders are the alkali metal salts of aminopolycarboxylic acids, such as ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA), diethylenetriamine pentaacetic acid tDEPTA), hydroxyethylaminodiacetic acid, etc.; ethane hydroxyphosphonic acids, aminophosphonic acids, etc.; polyelectrotlytes such as copolymers of ethylene with maleic anhydride; polyacrylates; alkenylsuccinates, etc.; soduim phytate. Suitable inorganic builders are anhydrous alkaline poly-, pyroand metaphosphates, silicates, borates, carbonates and the like. Also mixtures of organic and inorganic builders may be used. it is preferred that the organic builder in the compositions of the present invention is or comprises an alkali metal salt of nitrilotriacetic acid, in particular a hydrated alkali metal salt thereof. The amount of organic builders may be present in the composition may be from 1 to 70% by weight of the composition. For most commercial purposes the amount of organic builder may be from about 10% to about 60% by weight of the composition. The organic builder should have a particle size of less than 300 preferably less than 200g.

The weight ratio of the liquid detergent surfactant to organic builder should generally lie Within the range of 10 to l and 1 to 4, and for most commercial purposes within the range of 4:1 to 1:4, the preferred ratio being about 1:2.

The liquid detergent composition of the invention is ubstantially anhydrous, by which is to be understood that the final composition should not contain more than 5%. and preferably less than 2% by Weight of water. This does not include any water of hydration.

It has been found that the stabilities of the compositions are sometimes improved if they contain a small amount of water. It is believed that thereby the possible equilibrium reaction between silanol groups and alcohols at the surface of silica is shifted to the left. A small amount of water. in the order of a few tenths of percents is already sufiicient. The stability behaviour of the products may be further improved by the incorporation of a few percent of an emulsifier or a thixotropy maker, such as lauric diethanolamide, ethoxylated lanolin, disodium dioctyl sulfosuccinate and the like.

The viscosity of the composition will vary, depending upon its constituents. In order to ensure that the composition may be poured satisfactorily, it is preferred that the viscosity should be in the range of from to 3,000 cp.. although higher viscosities up to 10,000 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, etc.

In general the liquid detergent surfactant, the inorganic carrier material and the organic builder should together constitute at least 30% by weight of the final composition. Preferably they should constitute at least 50% by weight of the final composition. The final composition may even consist solely of the essential constituents, but usually the composition contains other materials which are considered normal and desirable additives in detergent compositions.

For instance, bleaching agents such as alkali metal perborates may be incorporated in an amount of from about 5 to about 30% by weight of the composition.

Without substantially modifying the fundamental characteristics of the compositions of the invention, there can furthermore be incorporated enzymes, such as amylases and proteases, lipases, colouring agents, fluorescers, bleaching agent precursors and activators, bleach stabilizers, perfumes, bactericides, soil suspending agents, corrosion inhibitors, alkali metal salts such as borates, carbonates, sulphates, silicates, and so on.

The invention is illustrated by the following examples in which the percentages and parts are by weight. The viscosities in all the examples were determined, after shaking, with the Brookfield viscometer, using spindle No. 4, at 60 r.p.m. at 25 C. The rates of the solution of the compositions were measured by first shaking and then adding the required amount (2.5 g./l. unless otherwise indicated) of the composition to water to 25 C., letting it stand for 1 minute and subsequently stirring the water and measuring the time necessary for the compositions to dissolve.
