Description

nomml IN OR RWATM n 9MMZ-c COMPOSITXQng
The present invention relates to liquid detergent compositions, especially compositions which dissolve and disperse satisfactorily in water.
Liquid detergent compositions comprising surfactants are known. Such compositions can be used, for example, for laundry use, for example for fine-fabric laundry use or for heavy duty laundry use, or as hand or machine dishwashing compositions. They may also be used in liquid toilet rim blocks and as hard surface cleaners. In general detergent compositions comprise a large amount of water. For example, hand dishwashing compositions often contain up to 80 wtt water. Such compositions do not generally have any compatibility problems when being diluted with a large
quantity of water.
I For some purposes it is desirable to have detergent compositions which are anhydrous or substantially anhydrous. However, such compositions may be difficult to disperse or dissolve in large quantities of water. In particular they may gel when diluted with water.
We have surprisingly discovered a composition which overcomes this problem of gelling.
Accordingly the present invention provides a liquid detergent composition comprising : a) an alkyl benzene sulfonic acid neutralised with an alkanolamine, said alkyl benzene sulfonic acid containing less than 20% of the 2-phenyl isomer; and b) an organic solvent : said composition containing less than 3 wt% water.
It is known that alkyl benzene sulfonic acids can be produced by a variety of processes in which an alkyl chain is attached to a benzene ring by a catalysed reaction. Various catalysts are known. It is usual in liquid detergents to use an alkyl benzene sulfonic acid produced using an AlC catalyst. Such alkyl benzene sulfonic acids typically contain at least 25% of the 2-phenyl isomer, that is the isomer in which the alkyl chain is attached to the benzene ring at the 2-position of the alkyl chain. The use of alkyl benzene sulfonic acids produced using other catalysts is in many cases avoided because they have disadvantages. For example, the alkyl benzene sulfonic acid produced by a process using a hydrogen fluoride (hop) catalyst is generally not used in aqueous compositions because the alkyl benzene sulfonic acid produced can give a cloudy appearance to the detergent composition, especially when used at a high concentration and in combination with electrolytes.
The liquid detergent composition of the present invention must contain an alkyl benzene sulfonic acid neutralised with an alkanol amine which contains less than 20% of the 2-phenyl isomer. Preferably it contains less than 15%, and more preferably less than 12% or less than 10% of the 2-phenyl isomer.
The alkyl benzene sulfonic acids produced using a HF catalyst contains less than 20% of the 2-phenyl isomer and can therefore be used in the present invention.
Such alkyl benzene sulfonic acids are commercially available, for example as Solfodac AC3-I from Condea or Petresul 550 from Petresa.
The alkyl benzene sulfonic acid may be produced using other catalysts, for example AlClj, if an additional
step, for example a separation step, is carried out to ensure that the final composition contains less than 20% of the 2-phenyl isomer in relation to the total amount of alkyl benzene sulfonic acid isomers present.
The alkyl benzene sulfonic acid contains other isomers, in particular the 3-, 4-, 5-and 6-phenyl isomers. These may be present in any proportions relative to each other. The alkyl chain may be linear or branched, although linear is preferred. The alkyl
chain is generally a C9-24 alkyl chain, for example a Cj alkyl chamA single alkylbenzene sulfonic acid, or a mixture of two or more, may be used.
The alkyl benzene sulfonic acid is neutralised with an alkanol amine. It is not possible to neutralise it with, for example, sodium or potassium hydroxide, since this leads to a solid product rather than a liquid product. The alkanol amine may contain one, two or three alkanol groups, which may be same or different. For example it can contain one, two or three methanol, ethanol, propanol or isopropanol groups. Desirably it is a monoethanolamine, diethanolamine or triethanolamine or a mixture thereof. Particularly desirable is a mixture of monoethanolamine and triethanolamine, for example in a weight ratio of from 1 : 1 to 1: 2, especially from 1 : 1.25 to 1: 1.75, more especially about 1: 1.5, which may lead to enhanced generation of foam.
The organic solvent may be any organic solvent, although it is desirable that it is miscible with water. Examples of organic solvents are glycols, glycerine or an alcohol. Preferred organic solvents are CI-4 alcohols such as ethanol or propanol, and Cl glycols such as monoethylene glycol and monopropylene glycol.
The composition of the present invention may contain further surfactants such as anionic, nonionic, amphoteric, cationic or zwitterionic surfactants, or a mixture thereof.
Anionic surfactants may include anionic organic surfactants, usually employed in soluble salt forms, preferably as alkali metal salts, especially as sodium salts. Although other types of anionic surfactants may be utilized, such as higher fatty acyl sarcosides, soaps of fatty acids (including metal soaps and amine soaps), preferred anionic surfactants are those which are described as of a sulfonate or sulfate type, which may be designated as sulfon) ates. These include linear higher alkylaryl sulfonates (for example alkylbenzene sulfonates), higher fatty alcohol sulfates, higher fatty alcohol polyalkoxylate sulfates, olefin sulfonates, a-methyl ester sulfonates and paraffin sulfonates. An extensive listing of anionic detergents, including such sulf (on) ate surfactants, is given on pages 25 to 138 of the text Surface Active Agents and Detergents, Vol. II, by Schwarz, Perry and Berch, published in 1958 by Interscience Publishers, Inc. Usually the higher alkyl group of such anionic surfactants has 8 to 24 carbon atoms, especially 10 to 20 carbon atoms, preferably 12 to 18 carbon atoms, and the alkoxylate content of such anionic surfactants that are alkoxylated (preferably ethoxylated or ethoxylated/propoxylated) is in the range of 1 to 4 moles of alkoxy groups per mole of surfactant.
One class of anionic surfactants comprise alkali metal (preferably sodium) alkylaryl sulfonates (especially alkylbenzene sulfonates), preferably having linear Cglz alkyl groups.
Another preferred class of anionic surfactants comprises alkali metal (preferably sodium) alkyl sulfates,
preferably having linear alkyl groups of 12 to 18 carbon atoms.
Another preferred class of anionic surfactants comprises alkali metal (preferably sodium) alkoxylated sulfates, preferably having linear alkyl groups of 12 to 18 carbon atoms, and preferably having 1 to 4 moles of alkoxy groups per mole of surfactant.
Non-ionic surfactants may be selected from, for example, alcohol alkoxylates such as alcohol ethoxylates, also known as alkylpoly (ethylene oxides) and-alkylpolyoxyethylene ethers, alkylphenol ethoxylates, ethylene oxide/propylene oxide block copolymers, alkyl polyglucosides, alkanolamides and amine oxides. Alcohol ethoxylates, alkylphenol ethoxylates and ethylene oxide/propylene oxide block copolymers are condensation products of higher alcohols with lower alkylene oxides.
In such non-ionic surfactants the higher fatty moiety will normally be of 11 to 15 carbon atoms and there will usually be present from 3 to 20, preferably from 3 to 15, more preferably from 3 to 10, and most preferably from 3 to 7, moles of alkylene oxide per mole of higher fatty alcohol.
Non-ionic surfactants of interest include alkyl polyglucosides, the hydrophobic carbon chain length varying from 8 to 16 carbon atoms depending on the feedstock (oleochemical or petrochemical) and the hydrophilic polyglucose chain length varying between one and more than eight units of glucose.
Amphoteric surfactants may be selected from, for example, alkyl betaines, alkylaryl betaines,
amidoalkyl betaines, imidazolinium-type beta. ines, sulfobetaines and sultaines.
The anionic surfactants, including the alkyl benzene sulfonic acid neutralised with an alkanolamine, are suitably present in a total amount of at least 10 wt%, and more preferably at least 20 wt% based on the total weight of the composition. The anionic surfactants are also suitably present in an amount of up to 95 wt%, preferably up to 70 wt%, more preferably up to 60 wt%, based on the total weight of the composition.
One or more non-ionic surfactant (s}, when present, is/are suitably present in an amount of at least 0.1 wt%, preferably at least 0.5 wt%, more preferably at least 1 wt%. Good compositions can also be prepared with higher amounts of non-ionic surfactant (s), for example in an amount of at least 2 wt%, preferably at least 4 wt%, and most preferably at least 8 wt%, based on the total weight of the composition. One or more non-ionic surfactant (s), when present, is/are suitably present in an amount of up to 80 wt%, preferably up to 70 wt%, more preferably up to 50 wt%, most preferably up to 35 wtt, and especially up to 20 wt%, based on the total weight of the composition.
One or more amphoteric surfactant (s), when present, is/are suitably present in an amount of at least 0.1 wt%, preferably at least 02 wt%, more preferably at least 04 wt%, based on the total weight of the composition. Good compositions can also be prepared with higher amounts of amphoteric surfactant (s), for example at least 1 wt%, preferably at least 2 wt%, more preferably at least 5 wt%, based on the total weight of the composition. One or more amphoteric surfactant (s), when present, is/are suitably present in an amount of up to 30 wt%, preferably up to 20%,
more preferably up to 15 wt%, based on the total weight of the composition.
A preferred laundry detergent composition includes as surfactant (s) the one or more alkyl benzene sulfonic acids neutralised by an alkanolamine, optionally one or more further anionic surfactants, and one or more non-ionic surfactant (s). Preferably such surfactant (s) is/are the only surfactant (s) or the major surfactant (s) present in the composition. By this we mean such surfactants including alkyl benzene sulfonic acids neutralised with an alkanolamine are present in a larger amount by weight than all other surfactant types in total, and preferably constitute at least 60 wt%, preferably at least 80 wt%, more preferably at least 95 wt%, and most preferably 100 wt% of the total weight of surfactants in the composition.
Especially preferred compositions employ the alkyl benzene sulfonic acid neutralised with an alkanolamine as the cleansing surfactant (s) and no further surfactants. Alternative preferred compositions also employ one or more non-ionic cleansing surfactants, the weight ratio of the former to the latter being at least 2: 1, preferably at least 4: 1.
The surfactants in total suitably provide at least 10 wt%, more preferably at least 20 wt%, most preferably at least 30 wt%, and especially at least 50 wtt of the total weight of a laundry detergent composition.
Suitably the surfactants in total provide (s) up to 99 wt%, especially up to 95 wtt, for example up to 70 wt%, of the total weight of the composition.
A detergent composition of the present invention may include one or more further components such as
desiccants, sequestrants, enzymes, silicones, emulsifying agents, viscosifiers, acids, bases, pH regulators (buffers), bleaches, bleach activators, hydrotropes, opacifiers, builders, foam controllers, solvents, preservatives, disinfectants, pearlising agents, limescale preventatives, such as citric acid, optical brighteners, dye transfer inhibitors, thickeners, gelling agents, colour fading inhibitors and aesthetic ingredients, for example fragrances and colourants.
Suitable foam controllers are soaps, for example based on coconut fatty acids. Such controllers may be present in an amount of up to 20 wt%, for example up to 10 wt%, preferably 1 to 5 wt%, especially 2 to 3
wt%, especially about 2. 5 wt%, of the composition based on the total amount of the composition.
The alkyl benzene sulfonic acid neutralised with an alkanolamine is preferably present in the composition of the present invention in an amount of up to 70 wt%, for example from 10 to 60 wt%. For concentrated compositions an amount of 40 to 60 wt% may be appropriate whereas for dilute compositions an amount of from 10 to 30 wt% may be more appropriate.
The organic solvent may be present in the composition in any amount, for example in an amount of up to 50 wt%. Preferably it is present in an amount of from 5 to 30 wt%, especially from 10 to 20 wt%, especially about 15 wt%.
The composition of the present invention contains less than 3 wt% water. Compositions containing more than 3 wt% water may not be stable on storage or may have a cloudy appearance. Desirably the composition contains less than 2 wt% water, even more desirably less than 1
wt% water. Most preferably, the composition is substantially anhydrous.
The liquid detergent composition of the present invention may have a wide variety of uses. Thus it may be used, for example, as a laundry detergent composition, for example, for fine fabrics such as wool or for heavy duty laundry use such as for a normal wash. It may also be used as a hard-surface cleaner or in a liquid toilet rim block of the type described in EP-A-538, 957 or EP-A-785,315. The composition may also be used as a hard-surface cleaning composition or as a liquid hand or machine dishwashing composition.
The present composition is especially suitable for use in a water-soluble container where the container is simply added to a large quantity of water and dissolves, releasing its contents. The favourable dissolution and dispersion properties of the composition of the present invention are particularly useful in this context.
Thus the present invention also provides a watersoluble container containing a composition as defined above.
The water-soluble container may comprise a thermoformed or injection moulded water-soluble polymer. It may also simply comprise a water-soluble film. Such containers are described, for example, in EP-A-524, 721, GB-A-2,244, 258, WO 92/17,381 and WO 00/55,068.
In all cases, the polymer is formed into a container or receptable such as a pouch which can receive the composition, which is filled with the composition and
then sealed, for example by heat sealing along the top of the container in vertical form-fill-processes or by laying a further sheet of water-soluble polymer or moulded polymer on top of the container and sealing it to the body of the container, for example by heat sealing.
Desirably the water-soluble polymer is a poly (vinyl alcohol) (PVOH). The PVOH may be partially or fully alcoholised or hydrolysed. For example, it may be from 40 to 100% preferably 70 to 92%, more preferably about 88%, alcoholised or hydrolysed, polyvinyl acetate. When the polymer is in film form, the film may be cast, blown or extruded.
The water-soluble polymer is generally cold water (20oC) soluble, but depending on its chemical nature, for example the degree of hydrolysis of the PVOH, may
be insoluble in cold water at 20oC, and only become soluble in warm water or hot water having a temperature of, for example, 30oC, 40oC, 50oC or even 60duc. Because the composition contains only up to 3 wt% water, the composition will not attack the PVOH container.
The containers of the present invention find particular use where a unit-dosage form of the composition is required. Thus, for example, the composition may be a dishwashing or laundry detergent composition, especially for use in a domestic washing machine. The use of the container may place restrictions on its size. Thus, for example, a suitable size for a container to be used in a laundry or dishwashing machine is a rounded cuboid container having a length of 1 to Scm, especially 3.5 to 4. 5cm, a width of 1.5 to 3.5cm, especially 2 to 3cm, and a height of 1 to 2cm, especially 1.25 to 1. 75cm. The
container may hold, for example, from 10 to 40g of the composition, especially from 15, 20 or 30 to 40g of the composition for laundry use or from 15 to 20g of the composition for dishwashing use.
The composition of the present invention may have a pH of, for example, 5 to 9, especially 5.5 to 7, more especially 5.5 to 6.5. The viscosity, measured using a Brookfield viscometer, model DV-II+, with spindle S31 at 12 RPM and at 20oC, is desirably 500 to 3000 cps, especially 800 to 1500 cps, more especially about 1100 cps.
The present invention is now further described in the following Examples, in which all of the parts are parts by weight unless otherwise mentioned.

Marlinat 242/90M is a C-Cl, alcohol polyethylene glycol (2EO), ether sulfate, monoisopropanolammmonium salt.
The composition was mixed until homogeneous. A Multivac thermoforming machine operating at 6 cycles/min. and at ambient conditions of 25C under 35% RH (i5% RH) was used to thermoform a PVOH film.
This was Monosol M8534 obtained Chris Craft Inc., Gary, Indiana, USA, having a degree of hydrolysis of 88% and a thickness of 100 um. The PVOH film was thermoformed into a rectangular mould of 39mm length, 29mm width and 16mm depth, with its bottom edges being rounded to a radius of 10mm at 115 to 118 C. The thus formed pocket was filled with 17ml of the above composition, and is 75 am thick film of Monosol M8534 PVOH was placed on top and heat sealed at 144 to 14SoC.
The detergent composition was found to dissolve satisfactorily in domestic laundry machines. It was also found to dissolve quickly when added to a large quantity of water having a hardness of 25 F at 20oC to provide a final solution containing the detergent composition in an amount of 5 wt%.
