Abstract

The invention aims at providing a pourable hand dish washing detergent that can be precisely dosed, provides excellent cleaning properties, is skin tolerable and stable to temperature and storage, wherein, optionally, the physically or chemically incompatible or sensitive ingredients are incorporated in a temperature, storage, transport stable and easy-to-use manner and presented in a corresponding optical form and wherein said ingredients are released before being directly used or during utilization. This is achieved by a thick, aqueous surfactant-containing agent with anion surfactant, amphoteric surfactant, polymer and microcapsules, in which one or more ingredients of the hand dish washing detergent are totally or partially included.

Description

"Dishwashing liquid with microcapsules"

The invention relates to thickened aqueous surfactant-containing agents, in particular hand dishwashing detergents, with anionic surfactant, amphoteric surfactant, polymer and microcapsules.

Attempts are made to use conventional agents to try out certain active ingredients (including skin feel-improving or nourishing additives such as liposomes, proteins, vitamins, plant extracts, etc .; performance-enhancing additives such as acetic acid, etc .; antibacterial additives such as lactic acid, benzoic acid, etc .; Esthetics (aesthetics, especially smell and appearance as well as haptics) improving additives, such as perfume oils, dyes, etc.) can be incorporated into a hand dishwashing liquid that can be precisely metered, excellently cleaned, skin-compatible, temperature and storage stable, pourable and ecologically particularly compatible there is a rapid loss of activity (e.g. with liposomes) due to the direct action of the surfactant components on the active ingredient. Another problem is the difficulty with the stable incorporation of active ingredients into the detergent formulation (e.g. with perfumes or antibacterial agents), discoloration (e.g. with plant extracts or proteins), odor problems (e.g. with the addition of vinegar, antibacterial agents or plant extracts) or incompatibilities between the active ingredient and the detergent.

An elegant method for incorporating sensitive, chemically or physically incompatible and volatile ingredients is the use of microcapsules, in which these ingredients are enclosed during storage and transportation and from which they are released mechanically, chemically, thermally or enzymatically for use.

Microcapsules are finely dispersed liquid or solid phases coated with film-forming polymers, in the production of which the polymers precipitate on the material (active ingredient) to be encased after emulsification and coacervation or interfacial polymerization. The active ingredient is enclosed in a shell-like membrane (microcapsule in the narrower sense) or enclosed in a matrix (microsphere or sphere). In the following, the term microcapsule is used in a summarizing sense for both variants, or if necessary both terms are placed side by side. The micro Skopically small capsules, also called nanocapsules, can be dried like powder. In this way, for example, gasoline, water, alcohol, pharmaceuticals, solvents, vitamins, enzymes, liquid crystals, food flavors and perfumes can be converted into a dry mass that cannot dry out. Microencapsulation is used, for example, for perfume powders, which are easier and longer effective to use as microcapsules.

From German published patent application DT 2 215 441 (Unilever NV), aqueous liquid dishwashing detergents with 20 to 45% by weight of anionic and / or nonionic surfactants, 3 to 10% by weight of electrolyte and capsules with a diameter of 1 to 4000 μm are made from the Polymer Carrageenan, polyvinyl alcohol or cellulose ether known, the polymer and the electrolyte concentration are selected so that the stability of the capsules in the agent and the dissolution of the capsules are guaranteed when diluted with water. Such a dishwashing detergent contains, for example, 10% by weight capsules with a diameter of 4000 μm, 25% by weight of sodium dodecylbenzenesulfonate, 5% by weight of coco monoethanolamide, 7% by weight of sodium sulfate, 1.5% by weight of synthetic clay or 5% by weight capsules with a diameter of 4000 μm, 20% by weight sodium alkylbenzenesulfonate, 5% by weight sodium C _14-16- α-olefin sulfonate, 5% by weight lauric acid diethanolamide, 7% by weight % Sodium xylene sulfonate, 3% by weight ethanol, 1% by weight potassium chloride,

1% by weight synthetic clay and 0.2% by weight EDTA.

DE 36 15 514 A1 (Lion Corp.) discloses an aqueous hand dishwashing detergent with 22% by weight sodium α-olefin sulfonate, 6% by weight magnesium alkylbenzenesulfonate,

2% by weight of sodium sulfate, 0.725% by weight of sodium chloride, 3% by weight of ethanol, 0.5% by weight of fragrance and 1.5% by weight of fragrance-containing microcapsules with a size of 200 to 500 μm, which can be found in the Dilute with water.

British Patent 1,471,406 (Unilever Ltd.) relates to liquid aqueous detergents containing at least 2% by weight of triethanolamine lauryl sulfate and a total of 8 to 50% by weight of surfactant and 0.5 to 2% by weight of water-soluble crosslinked polyacrylic acid with a molecular weight of more than 1,000,000 and 0.1 to 5% by weight of suspended phase, for example spheroidal capsules with a diameter of 0.1 to 5 mm, and have a pH of 5.5 to 11. The invention was based on the object of providing a precisely meterable, excellently cleaning, skin-compatible, temperature and storage stable, pourable hand dishwashing liquid in which the possibly physically or chemically incompatible or sensitive ingredients in temperature, storage and transport stable, easy to handle and are integrated in a visually appealing form and only release them immediately before or during use.

The invention relates to a thickened aqueous surfactant-containing agent, in particular hand dishwashing agent, containing anionic surfactant, amphoteric surfactant, polymer and microcapsules, in which one or more ingredients of the agent are wholly or partly enclosed.

In contrast to the ingredients related to the entire hand dishwashing detergent, the active ingredients only mean the part contained in the microcapsules.

The present invention also relates to the use of the agent according to the invention as a hand dishwashing agent.

In addition to crockery, the detergents are just as good at cleaning other hard surfaces made of glass, ceramic, plastic or metal in the home and business. Accordingly, the present invention further relates to the use of the agent according to the invention as a cleaning agent for hard surfaces.

The combination of anionic surfactant and amphoteric surfactant on the one hand brings about a particularly advantageous cleaning action and on the other hand, in conjunction with the polymer, a spatially particularly stable suspension of the microcapsules. The otherwise usual use of large amounts of electrolyte salt to stabilize the microcapsules is therefore not necessary. Visible microcapsules allow particularly precise, reproducible dosing by counting the microcapsules contained in the metered amount of hand dishwashing liquid.

In the context of the present invention, unless otherwise stated, fatty acids or fatty alcohols or their derivatives are representative of branched or unbranched carboxylic acids or alcohols or their derivatives, preferably having 6 to 22 carbon atoms. The former are preferred for ecological reasons, in particular because of their vegetable basis than based on renewable raw materials, without but to limit the teaching of the invention to them. In particular, the oxo alcohols or their derivatives obtainable, for example, according to ROELEΛ / oxo synthesis can also be used accordingly.

Whenever alkaline earth metals are mentioned in the following as counterions for monovalent anions, this means that the alkaline earth metal is naturally only present in half the amount of the substance - sufficient to balance the charge - like the anion.

INCI means that the following - or possibly preceding - name is a name according to the International Dictionary of Cosmetic Ingredients from The Cosmetic, Toiletry, and Fragrance Association (CTFA). The statement CAS means that the following sequence of numbers is a designation of the Chemical Abstracts Service.

Microcapsules

The microcapsules that can be used are all the surfactant-stable capsules and capsule materials or spheres and spherical materials available on the market, such as Hallcrest Microcapsules (capsule material gelatin, gum arabic) from Hallcrest, Ine (US), Coletica Thalaspheres (capsule material from Maritime Collica) (FR), Lipotec milk capsules (capsule material alginic acid, agar-agar) from Lipotec SA (ES), Induchem Unispheres (capsule material lactose, microcrystalline cellulose, hydroxypropylmethyl cellulose) and Unicenn C30 (capsule material lactose, microcrystalline cellulose (hydroxypropylmethyl cellulose), derypropylmethyl cellulose CH), Kobo Glycospheres (capsule material modified starch, fatty acid esters, phospholipids) and Softspheres (capsule material modified agar agar) from Kobo (US) as well as Kuhs Probiol Nanospheres (capsule material phospholipids) from Kuhs (DE) and others The microcapsules can have any shape in the production-related frame, but they are preferably ovoid or ellipsoidal or approximately spherical. Depending on the active ingredient and application, the diameter along its greatest spatial extent can be between 100 nm (not visually recognizable as a capsule) and 10 mm. The preferred diameter is in the range between 0.1 mm and 7 mm, microcapsules with a diameter between 0.4 mm and 5 mm are particularly preferred.

Active substances in the sense of the invention include dermatologically active substances such as vitamin A, vitamin B2, vitamin B12, vitamin C, vitamin E, D-panthenol, sericerin, collagen partial hydrolyzate, various vegetable protein partial hydrolyzates, protein hydrolyzate -Fatty acid condensates, liposomes, cholesterol, vegetable and animal oils such as Lecithin, soybean oil, etc., plant extracts such as e.g. Aloe vera, azulene, witch hazel extracts, algae extracts, etc., allantoin, A.H.A. complexes. Active substances in the sense of the invention are also antibacterial active substances, such as e.g. Benzoic acid, lactic acid, salicylic acid, sorbic acid or mixtures thereof or their salts. Among active ingredients within the meaning of the invention are essential oils such as. B. perfumes, limes, geraniol, nerol as well as additives to improve the wash load gloss, e.g. Understand vinegar. Colorants, color pigments or pearlescent components are added to improve the appearance.

Accordingly, in a preferred embodiment, the hand dishwashing detergent according to the invention contains microcapsules in which one or more representatives from the group comprising dermatologically active substances, antibacterial active substances, essential oils and additives for improving the wash load gloss and the appearance are included.

The active ingredient can be released from the microcapsules both by grinding the microcapsules during the cleaning process and by breaking them open using a suitable metering device. It is also conceivable to release the active ingredient by changing the temperature (introducing it into warm soapy water), by shifting the pH value, changing the electrolyte content, etc.

The content of microcapsules is usually from 0.01 to 10% by weight, preferably from 0.1 to 5% by weight, in particular from 0.2 to 3% by weight and extremely preferably from 0.3 to 2% by weight, wherein the agent according to the invention can contain only identical microcapsules or else mixtures of different types of microcapsules.

viscosity

The viscosity which is favorable for the agents according to the invention is at 20 ° C. and a shear rate of 10 s ^-1 between 300 and 20,000 mPa-s, preferably between 700 and 15,000 mPa-s, particularly preferably between 1,000 and 10,000 mPa-s, or at 20 ° C and a shear rate of 30 s ^{' 1} between 500 and 18,000 mPa-s, preferably between 700 and 13,000 mPa-s, particularly preferably between 900 and 10,000 mPa-s, in particular between 1,100 and 8,000 mPa-s, extremely preferably between 1,300 and 6,500 mPa-s, for example between 1,000 and 4,000 mPa-s.

Preferred zero shear viscosity values η ₀ for favorable storage properties are between 100 and 5,000 Pa s, preferably between 200 and 3,000 Pa s.

Many of the mixtures investigated according to the invention have a viscosity profile that changes over time. This is particularly desirable since a more fluid composition is preferred in the production process, but in terms of storage stability and ease of use, value is placed on higher-viscosity products.

The viscosity of the agents according to the invention can be adjusted by the polymer. The amounts required can vary from polymer to polymer. The surfactant composition used also plays a role in the choice of quantity, as does the presence of solubilizers.

Solution broker

As solubilizers, for example for dyes and perfume oils, for example alkanolamines, polyols such as ethylene glycol, 1, 2-propylene glycol, glycerol and other mono- and polyhydric alcohols and alkylbenzenesulfonates with 1 to 3 carbon atoms in the alkyl radical can be used.

To stabilize the hand dishwashing detergent according to the invention, in particular when the surfactant content is high, one or more dicarboxylic acids and / or their salts, alone or in a mixture, can be added, in particular a composition of Na salts of adipic, succinic and glutaric acid, such as those sold under the trade name Sokalan ^® DSC is available. The use here is advantageous in amounts of 0.1 to 8% by weight, preferably 0.5 to 7% by weight, in particular 1, 3 to 6% by weight and particularly preferably 2 to 4% by weight.

A change in the dicarboxylic acid (salt) content - especially in amounts above 2% by weight - can contribute to a clear solution of the ingredients. It is also possible to influence the viscosity of the mixture by this agent within certain limits. This component also influences the solubility of the mixture. This component is particularly preferably used at high surfactant contents, in particular at surfactant contents above 30% by weight.

Instead of or in addition to the dicarboxylic acids and / or their salts, other organic acids or their salts, such as, for example, sodium formate, sodium acetate, sodium citrate and sodium tartrate, and inorganic salts, such as e.g. Sodium chloride, magnesium chloride and magnesium sulfate, or also salts of the aforementioned anions with other alkali or alkaline earth metals can be used individually or in mixtures.

solvent

Another advantageous component of the agents according to the invention are solvents, in particular lower alcohols, preferably ethanol, n-propanol or / ^' so-propanol, particularly preferred ethanol. They contribute to the incorporation of perfume and dye, prevent the formation of liquid-crystalline phases and play a part in the formation of clear products. The viscosity can be reduced by increasing the amount of solvent. However, too much solvent causes the viscosity to drop too much. Therefore, according to the invention, one or more solvents are usually present in amounts of 0.1 to 12% by weight, preferably 1 to 10% by weight, particularly preferably 3 to 8% by weight, for example 5 to 6% by weight .

Auxiliaries and additives

A further improved cleaning performance, especially in the case of burnt-on dirt, is obtained when using abrasives, preferably water-soluble abrasives, in particular alkali metal bicarbonate, alkali metal sulfate.

In addition, other auxiliaries and additives customary in hand dishwashing detergents, in particular UV stabilizers, perfumes, pearlescent agents (INCI opacifying agents; for example glycol distearate, for example Cutina ^{1 '} AG S from Henkel KGaA, or be, usually no longer contain the Euperlane ^® from. Henkel KGaA), dyes, corrosion inhibitors and / or preservatives in amounts of 5 wt .-% as mixtures comprising, for example.

PH value

The pH of the agents according to the invention can be adjusted by means of customary pH regulators, for example citric acid or NaOH, a range from 5 to 8, preferably 5.5 to 7.5, in particular 5, essentially due to the required hand compatibility. 7 to 7 is preferred.

Manufacturing

The hand dishwashing detergents according to the invention can be produced by stirring the individual components together in any order. The order of preparation is not decisive for the preparation of the agent.

Water, surfactants and, if appropriate, further ingredients mentioned above are preferably stirred together. If perfume and / or dye are used, they are then added to the solution obtained. Finally, the polymer is added, optionally in the form of an aqueous solution, to facilitate its homogeneous dissolution. The pH is then adjusted as described above and the microcapsules are finally mixed in.

Examples

Agents E1 to E16 according to the invention were prepared as described above and their pH, viscosity and storage stability were determined.

The compositions of the agents E1 to E16 according to the invention in% by weight and the specific properties are shown in Tables 1 to 3. In addition, a number of the agents E1 to E16 according to the invention contained traces of dye. The pH of the agents E1 to E16 according to the invention was adjusted to between 5.5 and 7 with citric acid.

The viscosity of the agents E1 to E16 according to the invention was determined at 20.degree. C. according to Brookfield (viscometer βroo // e / o'V DV // +; spindle 25; rotational frequency 30 min ^"1 ).

The stability of the agents was checked by visually assessing the agents after four weeks' storage at room temperature of 20 ° C, at an elevated temperature of 40 ° C or in the cold at a temperature of 5 ° C. None of the agents showed - regardless of the storage temperature - a visually perceptible change after 4 weeks, in particular, neither a change in the shape of the capsules nor in their spatial distribution was observed on average.

The microcapsules used were clearly visible to the naked eye from a distance of approximately 0.5 m. The diameter of the microcapsules was 0.8 ± 0.4 mm in formulation E1, 2 ± 0.5 mm in formulations E2, E7, E10 and E15 and 4 ± 0.5 mm in formulations E5, E8, E11 and E14.

The rinsing performance of the recipes according to the invention was also largely determined - apart from E9, E10 and E16. The determination was determined in a semi-automatic plate test apparatus using two different pure grease stains I and II or a greasy mixed stain in an application concentration of 4 and / or 8 g / 10 l. The plates were soiled with the test dirt at a constant temperature of 40 or 45 ° C in 5 l of water with a hardness of 16 ° under constant conditions compared to a high-quality classic hand dishwashing liquid as a laboratory standard until the foam - which had formed before the start of the test - was destroyed was and the plates were no longer clean. The concentration of the agent was 4 or 8 g per liter of water. The number of dishes washed is shown in Tables 1 to 3 as a percentage in relation to a commercially available high-performance hand dishwashing detergent used as washing performance on the respective dirt at the concentration specified.

In particular, agents E3 to E7 and E15 demonstrate the superiority of inventive hand dishwashing detergents due to their high washing performance.
