Description

Liquid detergent composition.

The present invention describes compositions liquid detergents of the kind having a formed structure by active detergent material, the detergent structure - active exists as a separate dispersed phase within a phase predominantly watery. This aqueous phase normally contains dissolved electrolyte. In particular, the present invention describes structured detergent-active liquid compositions that contain significant levels of detergent materials not ionic

The present invention describes compositions liquid detergents that are "internally structured" in those that the structure is constituted by ingredients of primary active detergents.

Such structuring is well known in the technique and can be carried out deliberately to get features such as flow properties preferred by the consumer and / or turbidity aspect. Many liquids detergent-active structured may also have suspended solid particles such as detergency additives and abrasive particles

Some of the different kinds of structures of detergent - active possible are described in the reference HE HAS. Barnes, "Detergents", Ch.2. in K. Walters (Ed), "Rheometry: Industrial Applications" ("Rheometry: Industrial Applications"), J. Wiley & Sons, Letchworth 1980. In general, the degree of management of such systems grows with increasing concentrations of surfactant and / or electrolyte. At very low concentrations, the surfactant can exist as a molecular solution, or as a dissolution of spherical micelles, being in both cases isotropic. With the addition of more surfactant and / or electrolyte, they can be formed structured systems (anisotropic). They are called respectively with various terms such as bar micelles (rod - micelle), flat lamellar structures, lamellar drops and liquid crystalline phases. Frequently, various operators have used different terminologies to refer to structures of detergent - active which, in reality, are the same. For example, in the memory of European Patent EP-A-151 884, to the drops lamellars are called "spheroids." The presence and identity of a surfactant structuring system in a liquid can determined by means known to those skilled in the art, for example, optical techniques, various rheometric measurements, X-ray or neutron diffraction, and sometimes, electron microscopy

Electrolytes can be dissolved only in the aqueous phase continues or may also be present as solid particles suspended. Material particles solids that are insoluble in the aqueous phase may be suspended alternatively or additionally to any particle solid electrolyte.

Three common forms of products of this type are liquids for severe washing of fabrics, abrasive liquids and cleaning agents in general. In the first class, solids suspended can include suspended solids that are substantially the same dissolved electrolytes that are in excess exceeding the solubility limit. This solid is normally present as a detergency additive, that is, for counteract the hardness effects of water, which the ion produces calcium, in the wash. In the second class, suspended solids they usually comprise a particulate abrasive, insoluble in the system. In that case the electrolyte, present to contribute to the structuring of the active material in the dispersed phase, is generally different from abrasive compounds. In certain cases, however, the abrasive may partially include salts soluble that dissolve when the product is diluted. In the third class, the structure is normally used for the thickening of the product in order to provide the properties of flow preferred by the consumer, and sometimes to suspend pigment particles

The first class compositions are describe, for example, the memory of our patent EP-A - 38,101 while some examples of those in the second category are described in our specification EP-104,452. The third category, for example, are described in US 4,244,840.

It is believed that the detergent structure - active dispersed in these liquids consists of a layer configuration concentric comprising concentric bilayers of molecules detergent agents, among which water is retained (aqueous phase). These detergent-active material configurations are designated sometimes like lamellar drops. It is believed that the packaging Next of these drops allows solid materials to remain in suspension. Lamellar drops are themselves a subset of lamellar structures that can be formed in systems detergent - aqueous assets / electrolyte. In general, the systems of lamellar drops are a preferred category of structures that They may exist in liquid detergents.

The present invention describes compositions structured detergent-active detergents comprising a significant level of nonionic surfactants.

It has been suggested in GB 2 123 846 (Albright and Wilson) Examples 49 to 55, formulate detergent compositions structured detergent - active with high levels of nonionic materials. However, it is believed that the compositions suggested in these examples are not satisfactory due to their instability.

Nonionic materials with glycerol terminal can optionally be prepared by subjecting a higher alcohol C 9 -C 25, to an addition reaction with alkylene oxide, especially ethylene oxide followed by epichlorohydrin or glycerol in an inert atmosphere using a acid catalyst or an alkaline catalyst. In the case of epichlorine, alcohol is ethoxylated with 1 to 3 moles of oxide ethylene per molecule according to well known procedures. The product then reacts with 1 to 1.5 moles of epichlorohydrin in the presence of an acid catalyst and the product is  Treat with acetylated potassium hydroxide and hydrolyze.

wherein R is an alkyl or alkenyl group that has 7 to 18 carbon atoms, R1 is a hydrogen or a alkyl group having 1 to 4 carbon atoms and X is a part of carbohydrate that contains a pentose unit or hexose

Mixtures of the non-ionic materials indicated above.

Preferably the proportion of weights between the first non-ionic material and the second non-ionic material is between 10: 1 and 1:10, more preferably from 10: 1 to 1: 1, Especially preferred is 8: 1 to 2: 1, with the most preferred being 6: 1 to 3: 1.

Advantages have been found when using combinations of non-ionic materials containing materials whose length of hydrophobic chain is approximately equal. Preferably the ratio between the number of carbon atoms in the hydrophobic group of the first non-ionic material and the number of carbon atoms in the hydrophobic group of the second material not ionic is between 1.5: 1 and 1: 1.5, more preferably between 1.2: 1 and 1: 1.2.

The compositions according to the invention can Optionally include small amounts of anionic materials. These materials, when present, are at a lower level 50% by weight of the total active surfactant materials, plus preferably at a level less than 40% and especially preferred at a level less than 30%. Particularly preferred are formulations. containing less than 10% active anionic surfactants, it they prefer compositions that do not substantially comprise any anionic surfactant.

Suitable anionic surfactants are usually water-soluble alkali metal salts of organic sulfates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term "alkyl" being used to encompass the alkyl portion of higher acyl radicals. Examples of suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulfates, especially those obtained by sulfation of higher alcohols (C 8 -C 18) produced, for example, from coconut oil or grease, (C 9 -C 20) alkyl sodium and potassium benzene sulphonates, particularly C 10 -C 15 alkyl, secondary linear sodium benzene sulfonates; sodium alkyl glyceryl ether sulfates, especially the ethers of the higher alcohols derived from fat or coconut oil and synthetic petroleum-derived alcohols; monoglyceride sulfates and fatty sulfonates of sodium coconut oil; sodium and potassium salts (the sulfuric acid esters of alcohol oxide - higher fatty alkylene (C 8 -C 18), particularly ethylene oxide, reaction products; the reaction products of fatty acids such as fatty acids of coconut esterified with isethionic acid and neutralized with sodium hydroxide; sodium and potassium salts of methyl taurine fatty acid amides; alkane monosulfonates such as those derived from the reaction of alpha-olefins (C 8 -C 20) with sodium bisulfite and derivatives (the reaction of paraffins with SO2 and Cl2 and subsequent hydrolysis with a base to produce a random sulfonate; and olefin sulfonates, the term of which is used to describe the material formed by the reaction of the olefins, particularly C 10 -C 20 alpha olefins, with SO 3 and subsequent neutralization and hydrolysis of the reaction product.The preferred anionic detergent compounds are alkyl

It is also possible and sometimes preferred, include other anionic materials in the composition, such as alkaline metal soaps of a fatty acid, especially a soap of an acid having 12 to 18 carbon atoms, for example oleic acid, ricinoleic acid, and fatty acids derived from castor oil, rapeseed oil, peanut oil, coconut, palm seed oil or mixtures thereof. Can be used the sodium or potassium soaps of these acids.

In many cases (but not all), the material Active detergent can be from 2% to 60% by weight of the total composition, for example 5% to 40% and typically 10% 30% by weight.

Liquid compositions according to the present invention, preferably have a pH of about 7.0, being more preferred from 7.5 to 12.0, ideally between 8.5 and 11.0 a 25 ° C

The compositions according to the invention are with physically stable preference in that they produce no more than 2% by volume phase separation when stored at 25 ° C for 21 days from the moment of its preparation.

The viscosity of the compositions according to the The present invention is preferably less than 2500 mPas, more preferably less than 1500 mPas and especially preferred among 30 and 1000 mPas at 21 s -1.

A way to regulate viscosity and stability of the compositions according to the present invention is include polymeric viscosity regulating materials.

The viscosity regulating polymers and / or stability that are preferred for incorporation into compositions according to the invention include deflocculating polymers that have a hydrophilic skeleton and at least one side chain hydrophobic Such polymers are described, for example, in our European application 346 995, pending with the Present.

Defloculation polymers for use in detergent formulations according to this The invention can be of an anionic, non-ionic or cationic nature. Non-ionic defloculation polymers are preferred.

The hydrophilic polymer skeleton is typically a homo-, co- or ter-polymer containing groups carboxylic acids or (more preferably) their salt forms, by example maleate or acrylate polymers or copolymers of these together or with other monomer units such as vinyl ethers, styrene, etc. The hydrophobic chain or chains are selected typically, of saturated and unsaturated alkyl chains, for example which have 5 to 24 carbon atoms and are optionally bonded to the skeleton by means of an alkoxy or polyalkoxy linkage, by example a polyethoxy, polypropoxy or butyloxy bond (or mixtures of the same) that have 1 to 50 alkoxylene groups. So, in some forms the side chain (s) will essentially have the character of a nonionic surfactant. Preferred polymers are described in our European application patent 346 995, In process.

Preferably, the amount of polymer viscosity regulator is between 0, 1 and 5% in weight of the total composition, being more preferred between 0.2 and two%.

In many cases it is preferred that the aqueous phase continuous have dissolved electrolyte. As used in this document, the term electrolyte refers to any material Water soluble ionic. However, in drop dispersions lamellar, not all electrolyte is necessarily dissolved, but that there may be suspended solid particles because the Total electrolyte concentration of the liquid is greater than the solubility limit of the electrolyte. Can also be used mixtures of electrolytes, with tino or more of the electrolytes that they are in the dissolved aqueous phase and one or more that are substantially only in the suspended solid phase. They can also distribute two or more electrolytes approximately in proportion, Between these two phases. In part, this may depend on the procedure, for example, the order of addition of the components. On the other hand, the term "salts" comprises any material organic and inorganic that may be included, other than surfactants and water, whether or not ionic, and this term encompasses the subset of electrolytes (water soluble materials).

The only restriction of the total amount of active and electrolyte detergent material (if any) is that in the compositions of lamellar drops considered herein invention, together with them can occur the formation of a lamellar aqueous dispersion. Thus, in the scope of this invention a very wide variation in types and levels is possible of surfactant. Any expert in the art may select the types of surfactant and their proportions, in order to obtain a stable liquid with the required structure. However, it can mention that an important subclass of useful compositions is that in which the active detergent material comprises mixtures of different types of surfactants.

In the case of mixtures of surfactants, the precise proportions of each component that will result said stability and viscosity will depend on the type (s) and quantity (s) of electrolytes, as is the case with detergent structured liquids - conventional assets.

The compositions also optionally contain electrolyte in sufficient quantity to cause structuring of the active detergent material. Although preferably, the compositions contain from 1% to 60%, especially 10 to 10 45% of a salt displacement electrolyte. The electrolyte of saline displacement has the meaning described in memory of EP - A - 79 646, that is, all electrolytes that have a liotropic number less than 9.5. Optionally, they can be included also some saline retention electrolytes (as defined in later memory), provided it is of a class and in a quantity compatible with the other components, and that the composition still agree with the definition of the invention claimed here. Some or all electrolytes (either from salt retention or salt displacement), or any salt substantially insoluble in water that may be present, may have detergency additive properties. In any case, it prefers that the compositions according to the present invention include additive detergency materials, some of which or all They can be electrolytes. The additive material is anyone capable of reduce the level of free calcium ions in the wash solution and preferably will provide the composition with other properties beneficial such as the generation of an alkaline pH, the suspension of the dirt removed from the tissue and the dispersion of the clay fabric softener material.

Examples of inorganic detergent additives containing phosphorus, when present, include salts water soluble, especially alkali metal pyrophosphates, orthophosphates, polyphosphates and phosphonates. Specific examples of inorganic phosphate additives include tripolyphosphates, phosphates and sodium and potassium hexametaphosphates. Can also be used phosphonate inhibitor additives.

Examples of inorganic detergent additives that do not contain phosphorus, when present, include carbonates water-soluble alkali metal, bicarbonates, silicates and crystalline and amorphous aluminosilicates. Specific examples include sodium carbonate (with or without calcite particles), potassium carbonate, sodium and potassium bicarbonate, silicates and ceolites

In the context of inorganic additives, we prefer to include electrolytes that promote the solubility of other electrolytes, for example the use of potassium salts to promote the solubility of sodium salts. In this way, the amount of dissolved electrolyte can be increased considerably (crystalline solution) as described in the patent specification UK GB 1 302 543.

Examples of organic detergent additives, when present, include alkali metal, polyacetates of ammonium and substituted ammonium, carboxylates, polycarboxylates, polyacetyl carboxylates and polyhydroxysulfonates. Examples Specific are the sodium, potassium, lithium, ammonium and ammonium salts substituted of the following acids: acid ethylenediaminetetracetic, nitrilitriacetic acid, acid oxidisuccinic, CMOS, melitic acid, benzene acids polycarboxylic and citric acid.

Preferably the level of additive material not Soap is 0-50%, more preferably 2-40%, the more preferably 5-30% by weight of the composition.

In the context of organic additives, also it is convenient to incorporate polymers that are only partially dissolved in the continuous aqueous phase as described in EP 301,882. This allows a reduction in viscosity (due to polymer that is dissolved) while incorporating a amount high enough to make a profit secondary, especially constructive, because the part that is not dissolved does not cause instability that would occur if substantially everything was dissolved. Typical quantities are 0.5 to 4.5% by weight.

It is also possible to include in the compositions of the present invention, alternatively, or in addition to the polymer partially dissolved, yet another polymer that is substantially soluble entirely in the aqueous phase and have a resistance of electrolyte greater than 5 grams of sodium nitrilotriacetate in 100 ml of a 5% by weight aqueous solution of the polymer, having said second polymer also a vapor pressure in solution 20% aqueous, equal to or less than the vapor pressure of a 2% or more aqueous solution of polyethylene glycol reference which It has an average molecular weight of 6000; having said second polymer a molecular weight of at least 1000. The use of Such polymers are generally described in our EP 301,883.

The incorporation of the soluble polymer allows the formulation with better physical stability at the same viscosity (in compositional ratio without soluble polymer) or less viscosity with the same stability. Soluble polymer also can reduce the derived viscosity since it also produces viscosity reduction Here, the best stability and the least viscosity means overcoming any of the effects produced by the deflocculating polymer.

It is especially preferred to incorporate the polymer soluble with a partially dissolved polymer that has a large insoluble component. This is because although the ability to create of partially dissolved polymer is good (since they can stably incorporate relatively high amounts), the viscosity reduction will not be optimal (as it will dissolve little bit). In this way, the soluble polymer can have the function useful to reduce the additional viscosity, to an ideal level. The soluble polymer may, for example, be in a range that it comprises from 0.05 to 20% by weight, although it is usually sufficient with 0.1 to 2.5% by weight of the total composition, and especially 0.2 to 1.5% by weight. Frequently, levels above These can cause instability.

Although it is possible to incorporate smaller quantities of hydrotropes other than water miscible solvents, we prefer that the compositions of the present invention be substantially free of hydrotropes. Hydrotrope means any water soluble agent that tends to improve solubility  of the surfactants in aqueous solution.

In addition to the aforementioned ingredients, there may also be several optional ingredients, for example foam producers such as alkanolamides, particularly monoethanolamides derived from palm kernel fatty acids and coconut fatty acids, fabric softeners such as clays, amines and amine oxides, foam reducers, inorganic salts such as sodium sulfate and, normally present, in much smaller amounts fluorescent agents, perfumes, enzymes such as proteases, amylases and lipases (including Lipolase R ex Novo ), germicides and dyes .

Among these optional ingredients, as has been mentioned above, there are agents for whom dispersions, lamellar without deflocculant polymer have a highly sensitive stability and under this invention, can be incorporated in larger and more useful amounts. These agents cause a problem because they tend to promote flocculation of lamellar drops. Examples of such agents are fluorescents such as Blankophor R RHH, TinopaI R LMS, TinopaI R DMS-X and Blankophor R BBM, as well as agents chelators of metal, especially of the phosphonate type, for example the Dequest R range sold by Monsanto.

The compositions according to the invention can be prepared by procedures well known in the art. A particularly preferred procedure for the preparation of Compositions includes the formation of a non-aqueous pre-mixture comprising at least the two nonionic materials, followed by the dispersion of this pre-mixture in water. This procedure is particularly advantageous in that it cancels the difficulties in dissolution of the second non-ionic material less soluble in Water.
