DESCRIPTION

Improvements related to fabric conditioners

Technical field

The present invention relates to diluted fabric conditioning compositions containing unsaturated TEA quaternary ammonium compounds that are stable and offer both perfume and odor benefits.

Background and prior art

Chlorinated phenyl ethers and, in particular, "Diclosan" (4,4'-dichloro-2-hydroxy diphenyl ether) are known for their use in laundry products to give a persistent antimicrobial effect that resists exposure to high temperatures and therefore both survive the dryer. It is known that antimicrobials have a side effect in preventing bad odors through various microbial pathways. These may include (among others) odors generated by skin bacteria, such as Staphylococcus epidermidis, urine breakdown or growth of pathogenic bacteria such as Proteus vulgaris, and the formation of foot odor by Micrococcus dermatophytes. Many antimicrobial materials are known or have been suggested for use in laundry products.

The effectiveness of such compositions in reducing microbial growth can be measured by several tests. A well-known and standard test is the AATCC100 test, which measures bacterial growth in textile materials. Although treatments of industrial textile materials and fiber modification (such as the incorporation of silver ions) give good results in this and other tests, it has been shown that it is difficult to achieve good scores in these tests for both gram-positive and gram-negative bacteria through treatments which can be used at home in various washing conditions that end users apply.

Rinsing conditioners are a type of laundry product and are essentially metastable dispersions of fabric softening active substances in a solvent / water phase. The dispersions are formulated in such a way that they are stable in storage and in transit, but in use they become unstable and the fabric softening active substance is deposited on the items being treated. The stability of the formulation depends on the type of softening active substance being used and the levels of both the active substance and the other softening components. Loss of stability can lead to changes in viscosity or, even worse, to the visible separation of the components of the formulation. Changes in the microstructure of a product can have unexpected effects on the behavior of the perfume and vice versa. Even small changes in a formulation can have consequences in relation to stability.

Therefore, when changing the main active substance present in a rinse conditioner, that is, the cationic softening material, it is almost invariably the case that the new active substance cannot simply be replaced by the old one without having to do other formulation changes

Invention Statement

It has been determined that the combination of a quaternary active substance based on triethanolamine with a non-ionic antimicrobial gives a stable formulation base that reduces odor and can be perfumed. As will be discussed in more detail below, other antimicrobials did not give this benefit in combination with the particular base.

In a first aspect of the invention an aqueous fabric conditioning composition is provided, comprising:

(to)

from 0.5 to 35%, by weight of the total composition, of a fabric softener active substance, wherein the fabric softener active substance comprises an ester-bound quaternary ammonium compound of triethanolamine,

(b)

from 0.002% to 0.4% by weight of the total composition, of a non-ionic, antimicrobial active substance that is not a perfume component, and,

(C)

from 0.01 to 10%, by weight of the total composition, of a perfume.

As described in greater detail below, it is especially preferred that at least a part of the perfume is encapsulated, preferably in polymer-coated core encapsulates having a water insoluble cover.

Surprisingly, the compositions of the invention showed an unexpected improvement in the efficacy of the antimicrobial in a range of washing conditions. The synergistic combination of the conditioning active substance with Diclosan allows economically sustainable fabric softener formulations capable of giving rise to a persistent antimicrobial action for a wide range of household washing practices.

The non-ionic antimicrobial

Preferably, the non-ionic antimicrobial is a halogenated material. Suitable materials include 5-chloro2- (2,4-dichlorophenoxy) phenol, o-benzyl-p-chlorophenol, and 4-chloro-3-methylphenol.

Alternatively, the material may be non-halogenated. Examples of suitable materials include 2-phenylphenol and 2- (1-hydroxy-1-methyl ethyl) -5-methylcyclohexanol.

Phenyl ethers are a preferred subset of non-ionic antimicrobials.

More preferably, the non-ionic antimicrobial is a bihalogenated compound. Most preferably, this comprises 4,4'-dichloro-2-hydroxy diphenyl ether and / or 2,2-dibromo-3-nitrilopropionamide (DBNPA). If the latter is used, the pH of the composition should be in the acidic range, where the DBNPA is stable. This does not present any difficulty with the rinse conditioning compositions, since they are usually formulated in that range.

The nonionic microbial active substance is present in an amount of from 0.002% to 0.4% by weight of the total composition. The preferred inclusion range for the non-ionic microbial active substance is 0.025 to 0.1% by weight, by weight of the total composition.

Suitable materials are known in the market as "Diclosan" and are available as products such as Tinosan ™ HP 100 example of BASF.

In addition to non-ionic antimicrobial agents, other antimicrobial agents may also be present, provided that they are not present at a level that causes instability in the formulation. Among such other useful additional antimicrobial agents are chelating agents, which are particularly useful in reducing the resistance of gram-negative microbes in hard water. Acid biocides may also be present.

In one aspect of the invention, the process for preparing the perfume particles is preferably a two-stage process, in which the first stage forms a particle comprising the beneficial agent and the second stage applies a coating to the capsule which includes a deposition adjuvant.

The first stage may be a stepwise growth or addition polymerization and the second stage is preferably addition polymerization.

In the alternative a particle can be formed that does not contain the perfume, but is capable of adsorbing it at some later time. Then, this particle is optionally decorated with the deposition aid, thus performing a two-stage procedure analogous to that described above. Then, the particle is exposed to the perfume, which diffuses into the particle. Conveniently, this can be done in the product, for example by adding the particles with deposition adjuvant to a partially or fully formulated product containing the perfume. Then, the perfume is adsorbed by the particle and retained within the particle during the use of the product, whereby at least part of the perfume is released from the particles after the fabric treatment procedure, when the particles have been deposited on the cloth.

A single stage encapsulation can also be used. In general, particles encapsulated in a single stage have an adjuvant deposition. The single-stage perfume particles can be formed by stepwise growth polymerization or addition polymerization.

Suitable classes of monomers for stepwise polymerization are given in the group consisting of the melamine / urea formaldehyde class, the isocyanate / diol class (preferably polyurethanes) and polyesters.

Melamine / urea formaldehyde and polyurethane classes are preferred.

Suitable classes of monomers for addition / free radical polymerization are provided in the group consisting of olefins, ethylene, vinyl aromatic monomers, vinyl alcohol esters with mono and dicarboxylic acids, esters of α, β-monoethylenically unsaturated mono and dicarboxylic acids with alcohols, nitriles of α, β-monoethylenically unsaturated mono and dicarboxylic acids, conjugated dienes, α, β-monoethylenically unsaturated mono and dicarboxylic acids and their amides, methacrylic acid and its esters with alcohols and diols, dimethyl or dibutyl maleate and acid vinyl sulfonic and its water-soluble salts, and mixtures thereof. The polymeric particle may comprise mixtures of monomer units.

The polymeric particle may optionally comprise monomers that are crosslinkers. Such crosslinkers may have at least two unsaturated double bonds not ethylenically conjugated. Examples are alkylene glycol diacrylates and dimethacrylates. An additional type of suitable crosslinking monomers are those that are conjugated, such as divinyl benzene. If present, these monomers constitute 0.1 to 10% by weight, based on the total amount of monomers to be polymerized.

The monomers are preferably selected from: styrene; α-methyl styrene; o-chlorostyrene; vinyl acetate; vinyl propionate; vinyl n-butyrate; esters of acrylic, methacrylic, maleic, fumaric or itaconic acid with methyl, ethyl, n-butyl, isobutyl, n-hexyl and 2-ethylhexyl alcohol; 1,3-butadiene; 2,3 dimethyl butadiene; and isoprene. Preferred monomers are vinyl acetate and methyl acrylate.

Optionally, the monomers are used as comonomers with one or more of acrylic acid, methacrylic acid, maleic acid, fumaric acid, itaconic acid, monoacrylates and monomethacrylates of poly (alkylene oxide), N-vinyl pyrrolidone, methacrylic and acrylic acid, acrylates and 2-hydroxyethyl methacrylates, glycerol acrylates and methacrylates, methacrylates and acrylates of poly (ethylene glycol), N-vinyl pyrrolidone, acryloyl morpholine, vinyl formamide, n-vinylacetamide and vinyl caprolactone, acrylonitrile (71 g / l), 71 g / l) and methacrylamide at levels of less than 10% by weight of the monomer unit content of the particle; 2- (dimethylamino) ethyl methacrylate, 2 (diethylamino) ethyl methacrylate, 2- (tert-butylamino) ethyl methacrylate, 2-aminoethyl methacrylate, 2- (2-oxo-1imidazolidinyl) ethyl methacrylate, vinylpyridine, vinylcarbazole , vinyl imidazole, vinyl aniline, and its cationic forms after treatment with alkyl halides.

Optional crosslinkers include vinyl toluenes, divinylbenzene, ethylene glycol diacrylate, 1,2-propylene glycol, 1,3-propylene glycol diacrylate, 1,3-butylene glycol diacrylate, 1,4-butylene glycol diacrylates, ethylene glycol dimethacrylate, 1,2-dimethacrylate -propylene glycol, 1,3-propylene glycol dimethacrylate, 1,3butylene glycol dimethacrylate, 1,4-butylene glycol dimethacrylate, divinylbenzene, vinyl methacrylate, vinyl acrylate, allyl methacrylate, allyl acrylate, diallyl malate of diallyl, methylene bisacrylamide, cyclopentadienyl acrylate, and triallyl cyanurate.

It is preferable that the ratio of the monomers used in the formation of the general cover and those used in the fixation of the deposition adjuvant are the ratio of 100: 1 to 5: 1 (as a mass cover former: linker of the deposition) Preferably, the ratio is 100: 1-50: 1.

As indicated above, the process for preparing the particles is preferably a two-stage process, in which the first stage forms a capsule around the beneficial agent and the

Second stage applies a coating to the capsule that includes a deposition aid. The first stage may be a stepwise growth or addition polymerization and the second stage is preferably addition polymerization.

It is particularly preferable that the first stage uses monomers selected from melamine / ureaformaldehyde or methyl methacrylate or isocyanate / diol, and the second stage uses monomers selected from vinyl acetate and / or methyl acrylate. It is particularly preferred that the deposition aid is not added until the second stage.

For stage polymerization, some heating is generally required to cause polymerization to proceed. Initiators and chain transfer agents may also be present in the polymerization mixture in which use is made of any addition polymerization. Those skilled in the art will recognize that in general a chemical initiator will be necessary for addition polymerization, but that there are cases in which alternative forms of initiation will be possible, for example, ultrasonic initiation or irradiation initiation.

The initiator is preferably a chemical or chemical products capable of forming free radicals. Normally, free radicals can be formed either by homolytic cleavage (i.e., homolysis) of a single bond or by transfer of individual electrons to or from an ion or molecule (e.g., redox reactions). Suitably, in the context of the invention, homolysis can be achieved by the application of heat (usually in the range of 50 to 100 ° C). Some examples of suitable initiators in this class are those that possess peroxide (-OO-) or azo (-N = N-) groups, such as benzoyl peroxide, t-butyl peroxide, hydrogen peroxide, azobisisobutyronitrile and ammonium persulfate . Homolysis can also be achieved by the action of radiation (usually ultraviolet), in which case it is called photolysis. Examples are the dissociation of 2,2'azobis (2-cyanopropane) and the formation of free radicals from benzophenone and benzoin. Redox reactions can also be used to generate free radicals. In this case an oxidizing agent is paired with a reducing agent, which then undergo a redox reaction. Some examples of suitable pairs in the context of the invention are ammonium persulfate / sodium metabisulfite, cumyl hydroperoxide / ferrous ion and hydrogen peroxide acid / ascorbic.

Preferred initiators are selected from the following group:

Homolytics: benzoyl peroxide, t-butyl peroxide, hydrogen peroxide, azobisisobutyronitrile, ammonium persulfate, 2,2'-azobis (cyanopropane), benzophenone, benzoin,

Redox: mixture of ammonium persulfate / sodium metabisulfite, mixture of cumyl hydroperoxide / ferrous ion and / or mixture of hydrogen peroxide / ascorbic acid.

Preferred initiators are ammonium persulfate and the mixture of hydrogen peroxide / ascorbic acid. The preferred level of initiator is in the range of 0.1 to 5.0% w / w by weight of the monomer, more preferably, the level is in the range of 1.0 to 3.0% w / w by weight of the monomer. monomer

Optionally, chain transfer agents can be used. A chain transfer agent contains very labile hydrogen atoms that are easily abstracted by a propagation polymer chain. This terminates the polymerization of the growing polymer, but generates a new reactive site in the chain transfer agent which can then proceed to initiate further polymerization of the remaining monomer. Chain transfer agents in the context of the invention typically contain the thiol (mercaptan) functionality and may be represented by the general RS-H chemical formula, such as n-dodecyl mercaptan and 2-mercaptoethanol. Preferred chain transfer agents are monothioglycerol and n-dodecyl mercaptan, used at levels of preferably 0 to 5% w / w based on the weight of the monomer and more preferably at a level of 0.25% w / w based in the weight of the monomer.

Although it is preferred to use polymer particles, preferably core-encapsulated capsules, many other types of particles can be provided. as the perfume vehicle, and then encapsulate. Perfumes have been adsorbed onto a clay or zeolite material which is then mixed in detergent particulate compositions: US Patent No. 4,539,135 discloses particulate casting compounds comprising a clay or zeolite material bearing perfume . Perfume combinations generally with larger pore zeolites such as zeolite X and Y are also taught in the art. East German Patent Publication No. 248,508 refers to perfume dispensers containing a faujasite-type zeolite (eg, zeolite X and Y) loaded with perfume. In addition, East German Patent Publication No. 137,599, published on September 12, 1979 teaches compositions for use in powder washing agents to provide thermo-regulated perfume release. Zeolites A, X and Y are taught for use in these compositions. Other perfume release systems are taught in WO 97/34982 and WO 98/41607, published by The Procter & Gamble. WO 97/34982 discloses particles comprising perfume-laden zeolite and a release barrier, which is an agent derived from a wax and having a size (i.e., a cross-sectional area) larger than the size of the pore openings of the zeolite vehicle. WO 98/41607 discloses vitreous particles comprising agents useful for washing

laundry or cleaning compositions and a crystal derived from one or more of the hydroxylic compounds at least partially soluble in water.

Silicas, amorphous silicates, non-stratified crystalline silicates, stratified silicates, calcium carbonates, double salts of calcium / sodium carbonate, sodium carbonates, sodalites, alkali metal phosphates, pectin, chitin microbeads, carboxy alkylcelluloses, gums, resins, gelatin, gum arabic, porous starches, modified starches, carboxyalkyl starches, cyclodextrins, maltodextrins, synthetic polymers such as polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), cellulose ethers, polystyrene, polyacrylates, polymethyl acrylates, poly-acrylates and mixtures thereof can all provide a base for perfume particles.

However, polymer particles are preferred, especially polymer particles comprising a water insoluble shell comprising an aminoplast polymer. These include core shell encapsulates of which the water insoluble shell comprises the reaction product of an amine selected from urea and melamine, or mixtures thereof, and an aldehyde selected from formaldehyde, acetaldehyde, glutaraldehyde

or mixtures thereof.

Perfume-bearing particles are typically of a size (measured as D4.3) between 100 nanometers and 50 micrometers. Particles larger than this are entering the visible range.

The preferred particle size range is in the submicron range in the micrometer range.

Suitable particles in the submicron range include nanoparticles, latex, and miniemulsion products with a typical size range of 100-600 nanometers.

Suitable particles in the micrometer range include known types of aminoplast encapsulates, silica, clays, starch and zeolite particles and coacervated with a typical size range of 1-50 micrometers, preferably 5-30 micrometers.

As mentioned above, the particles may be provided with a deposition aid. These are polymeric materials fixed to the outer surface of the particle that are nouns for cotton and / or polyester. Suitable deposition aids include natural or modified polysaccharides that are nouns for cotton and / or polyester, or phthalate-containing species that are nouns for cotton and / or polyester.

Useful components of the perfume include both natural and synthetic materials. They include individual compounds and mixtures. Specific examples of these components can be found in the current literature, p. eg, in Fenaroli’s Handbook of Flavor Ingredients, 1975, CRC Press; Synthetic Food Adjuncts, 1947 by M. B. Jacobs, edited by Van Nostrand; o Perfume and Flavor Chemicals by S. Arctander 1969, Montclair, N.J. (USA.). These substances are well known to the person skilled in the art of perfuming, flavoring and / or aromatizing consumer products, that is, of conferring a smell and / or a taste or taste to a traditionally scented or flavored consumer product, or modify the smell and / or taste of said consumer product.

In this context, perfume not only means a fully formulated product fragrance, but also selected components of that fragrance, particularly those that tend to get lost, such as the so-called 'high notes'.

Poucher (Journal of the Society of Cosmetic Chemists 6 (2): 80 [1955]) defines the high marks. Examples of well-known high notes include citrus oils, linalool, linalyl acetate, lavender, dihydromyrcenol, rose oxide and cis-3-hexanol. Typically, the high notes comprise 15-25% by weight of a perfume composition and in those embodiments of the invention that contain an increased concentration of high notes, it is anticipated that at least 20% by weight are present within the form encapsulated

Typical perfume components that are advantageous to encapsulate include those that have a relatively low boiling point, preferably those that have a boiling point of less than 300, preferably 100-250 degrees Celsius and profragances that such components can produce.

It is also advantageous to encapsulate perfume components that have a low Clog P (ie, those that will be distributed in water), preferably with a Clog P of less than 3.0. These relatively low boiling and relatively low Clog P materials have been called the "late blooming" perfume ingredients and include the following materials:

allyl caproate, amyl acetate, amyl propionate, anisic aldehyde, anisole, benzaldehyde, benzyl acetate, benzyl acetone, benzyl alcohol, benzyl formate, benzyl isovalerate, benzyl propionate, beta gamma hexenol, camphor gum, levo-carvone, d-carvone, cinnamic alcohol, cinnamyl formate, cis-jasmona, cis-3-hexenyl acetate, cuminic alcohol, cyclal C, carbinol dimethyl benzyl, dimethylbenzylcarbinol, ethyl acetate, ethyl acetoacetate, ethyl amyl ketone, ethyl benzoate, butyrate

Preferred non-encapsulated perfume ingredients are those hydrophobic perfume components with a Clog P above 3. As used herein, the term "ClogP" means the logarithm calculated on the basis of the octanol / water partition coefficient. (P). The octanol / water partition coefficient of a PRM is the ratio between its concentrations in the octanol and water equilibrium. Since this measure is a proportion of the concentration in the equilibrium of a PRM in a non-polar solvent (octanol) with its concentration in a polar solvent (water), Clog P is also a measure of the hydrophobicity of a material - the more High is the value of Clog P, the more hydrophobic is the material. Clog P values can be easily calculated from a program called "CLOGP" that is available from Daylight Chemical Information Systems Inc., Irvine Calif., USA.

An oily sugar derivative is a liquid or soft solid derivative of a cyclic polyol (CPE) or a reduced saccharide (RSE), said derivative resulting from 35 to 100% of the hydroxyl groups in said polyol or in said saccharide which It is esterified or etherified. The derivative has two or more ester or ether groups independently linked to a C8-C22 alkyl or alkenyl chain.

Advantageously, the CPE or RSE does not have a substantial crystalline character at 20 ° C. Instead, it is preferably in a liquid or soft solid state as defined herein at 20 ° C.

Liquid or soft solid CPE or CSR (as defined above) suitable for use in the present invention result from 35 to 100% of the hydroxyl groups of the starting cyclic polyol or groups of the starting cyclic polyol or the reduced starting saccharide being esterified or etherifying with groups such that the CPEs or CSRs are in the liquid state or in the soft solid state. These groups typically contain unsaturation, branching or mixed chain lengths.

Typically CPEs or CSRs have 3 or more ester or ether groups or mixtures thereof, for example 3 to 8, especially 3 to 5. It is preferred if two or more of the ester or ether groups of the CPE or RSE are independently linked from each other to a C8 to C22 alkyl or alkenyl chain. The C8 to C22 alkyl or alkenyl groups may be branched or linear carbon chains.

Preferably 35 to 85% of the hydroxyl groups, most preferably 40-80%, even more preferably 45-75%, such as 45-70% are esterified or etherified.

Preferably, the CPE or the RSE contain at least 35% of esters or higher esters, for example at least 40%.

The CPE or the RSE has at least one of the chains independently linked to the ester or ether groups having at least one unsaturated bond. This provides a cost effective way to make the CPE or CSR a liquid or a soft solid. This is preferred if predominantly unsaturated fatty chains, derived from, for example, rapeseed oil, cottonseed oil, soybean oil, oleic, tallow, palmitoleic, linoleic, erucic or other sources of unsaturated vegetable fatty acids, are linked to the ester / ether groups.

These chains are referred to below as the ester or ether chains (of the CPE or RSE).

The ester or ether chains of the CPE or RSE are preferably predominantly unsaturated. CPEs or CSRs include sucrose tetrasebacate, sucrose tetracolcinate, sucrose tetraoleate, sucrose tetraesters of soybean oil or cottonseed oil, cellobiose tetraoleate, cellobiose trioleate, sucrose tricolzate, sucrose pentaoleate, pentacholine of sucrose, sucrose hexaoleate, sucrose hexacolzate, sucrose triesters, pentaesters and hexaesters of soybean oil or cottonseed oil, glucose trioleate, glucose tetraoleate, xylose trioleate, or tetra-, tri-, penta -o sucrose hexa-esters with any mixture of predominantly unsaturated fatty acid chains.

The most preferred CPEs or CSRs are those with monosaturated fatty acid chains, that is, where any polyunsaturation has been removed by partial hydrogenation. However, some CPE or CSR based on polyunsaturated fatty acids, for example sucrose tetralinoleate, can be used since most of the polyunsaturation has been removed by partial hydrogenation.

The most highly preferred liquid CPEs or CSRs are some of the above but where polyunsaturation has been removed by partial hydrogenation. Preferably 40% or more of the fatty acid chains contain an unsaturated bond, more preferably 50% or more, most preferably 60% or more. In most cases 65% to 100%, for example 65% to 95% contain an unsaturated bond.

CPEs are preferred for use with the present invention. Inositol is a preferred example of a cyclic polyol. Inositol derivatives are especially preferred.

In the context of the present invention, the term cyclic polyol encompasses all forms of saccharides. In fact, saccharides are especially preferred for use with this invention. Examples of preferred saccharides for CPE or CSR to be derived from them are monosaccharides and disaccharides.

Examples of monosaccharides include xylose, arabinose, galactose, fructose, sorbose and glucose. Glucose is especially preferred. Examples of disaccharides include maltose, lactose, cellobiose and sucrose. Sucrose is especially preferred. An example of reduced saccharin is sorbitan.

Liquid or soft solid CPEs can be prepared by procedures well known to those skilled in the art. These include acylation of the cyclic polyol or reduced saccharide with an acid chloride, transesterification of the cyclic polyol or esters of reduced saccharide fatty acids using a variety of catalysts; acylation of the cyclic polyol or the reduced saccharide with an acid anhydride and acylation of the cyclic polyol or the reduced saccharide with a fatty acid. See, for example, US 4 386 213 and AU 14416/88 (both from P&G).

This is preferred if the CPE or RSE has 3 or more, preferably 4 or more ester or ether groups. If the CPE is a disaccharide it is preferred if the disaccharide has 3 or more ester groups or ether groups. Particularly preferred CPEs are esters with an esterification degree of 3 to 5, for example, tri, tetra and penta esters of sucrose.

Where the cyclic polyol is a reducing sugar it is advantageous if each ring of the CPE has an ether or ester group, preferably in the C1 position. Suitable examples of such compounds include methylglucose derivatives.

Examples of suitable CPE include alkyl (poly) glycoside esters, in particular alkylglucoside esters having a polymerization degree of 1 to 2.

The length of unsaturated chains (and saturated if present) in the CPE or RSE is C8-C22, preferably C12-C22. It is possible to include one or more C1-C8 alkyl chains, however, these are less preferred.

Liquid or soft solid CPEs or CSRs for use in the present invention are characterized as materials having a solid: liquid ratio between 50:50 and 0: 100 at 20 ° C as determined by relaxation time T2 of NMR, preferably between 43:57 and 0: 100, most preferably between 40:60 and 0: 100, such as, 20:80 and

0: 100 The T2 NMR relaxation time is commonly used to characterize solid: liquid proportions in soft solid products such as fats and margarines. For the purpose of the present invention, any component of the signal with a T2 of less than 100 μs is considered to be a solid component and any component with T2 ≥ 100 μs is considered to be a liquid component.

For CPEs and CSRs, the prefixes (for example tetra and penta) indicate only the average degrees of esterification. The compounds exist as a mixture of materials that vary from monoester to fully esterified ester. It is the average degree of esterification used in this document to define CPEs and CSRs. The HLB of the CPE or the RSE is typically between 1 and 3.

Where present, the CPE or RSE is preferably present in the composition in an amount of 0.5-50% by weight, based on the total weight of the composition, more preferably 1-30% by weight, such as 2-25 %, for example 2-20%.

The CPEs and RSEs for use in the compositions of the invention include sucrose tetraoleate, sucrose pentaerucate, sucrose tetraerucate and sucrose pentaoleate.

Example 2: stability test:

20 Response to the dose by weight of Diclosan on the basis of ASD as described in Example No. 1 for viscosity at 84 days of storage gave the results presented in the table below at the temperature as indicated. The viscosity (mPas) was measured at 106 sec-1. It will be seen that, except in the harshest conditions, the viscosity of the product remained within the preferred range of 55-200 mPas and the trend is towards a better viscosity stability as more Diclosan is included.

Example 5: Synergistic interaction with the active substance.

The treated fabric (~ 10g) was quantitatively extracted by repeated reflux and concentration in ethanol (Soxhlet extraction). After fifteen cycles of extraction, the volume of ethanol was reduced to 5 to 10 mls, allowed to cool and weighed accurately.

An aliquot was taken and made alkaline by the addition of an equal volume of aqueous NaOH (0.01 M); After this step, the mixture was centrifuged to remove any solid and an aliquot of the supernatant was taken for high performance liquid chromatography (HPLC). An Agilent 1100 HPLC separation column

20 equipped with guard and Hypersil ODS (C18) was used with an eluent comprising 70 parts of acetonitrile to 30 parts of aqueous buffer of 0.03M H3PO4 / 0.0825M Na2HPO4

One microliter of the alkaline extract was injected and eluted at 1.5 ml / min through the column, incubated at 40 ° C and with a UV-vis diode array detection. It was found that Diclosan had a retention time of approximately 4.2 minutes, was quantifiable at 280 nm or 210 nm by reference to a previously calibrated

25 determined and clearly separated from other compounds extracted from the fabric.

The TEA 2 base with and without 0.05% by weight of Diclosan was prepared as indicated in the following table.

The TEA 2 base was used in the final rinse in 35 g doses using European washing conditions, that is, a Zanusi FLA machine at 40 ° C, cotton program, with a wash load comprising 1.5 kg of point of cotton and 1.5 kg of polyester in which the main thing was carried out using a dose of 85 g of Persil

5 non-biol powder detergent in water 26ºFH. After drying, the cotton spot of these washes was analyzed using the AATCC TM100 surface procedure.

Fabrics treated with Diclosan were also prepared by uniform humidification of the fabric with Diclosan solutions (90:10 in water: ethanol) and then evaporating to dryness. Diclosan levels retained in the fabric were extracted and quantified as previously described. These fabrics treated with Diclosan are

10 analyzed using the AATCC TM100 surface procedure. This procedure provides an indication of the dose response of the Diclosan level necessary to achieve a reduction in bacterial growth.

The results of the AATCC TM100 test and the Diclosan levels recovered are presented in the following table. Examples 5.B-5.G below provide data for drying solutions and examples 5.A and 5.1 provide data for fully formulated products.

Extraction of the cotton knitted fabric treated with the TEA 2 base containing 0.05% by weight of Diclosan reveals that Diclosan deposition is 2.5 mg / kg of cotton (est. Deviation = 0.8 ), and a reduction better than 4 log (number of bacteria) was obtained (example 5.1). This observation is consistent with a synergistic contribution to

20 kill from the base, from the examples of direct dose / response 5.B to 5.G the deposition of Diclosan only at levels greater than 6 mg / kg (examples 5.E-5.G) was necessary for a reduction of 4 log in S aureus.
