Description

Foaming system and compositions detergents containing the same.

Field of the Invention

This invention relates to a new system of Foaming useful in a detergent composition. Plus particularly, the present invention relates to compositions granular detergents intended to clean tissues containing New foaming components.

Background of the invention

Foaming is desirable in various applications, such as during the washing process. In compositions detergents, specific surfactants are known for provide foaming in the wash water. The formation Foam or soaps is not only desirable, it is also desirable easily create foam and keep the foam for a duration desired. For example, it may be desirable for the foam to be produced. immediately upon contact with a detergent composition with water. Although there are several reasons why you want the formation of foam, a known reason is that consumers who use detergent compositions directly associate the formation of foam with the cleaning capacity of the detergent composition.

Although foaming is desirable, the Foam can pose problems during the washing process. By example, the drain of the soaps or foam during the process Washing can be difficult. Specifically for a washing process by machine, soaps or foam can prevent drainage of the washing solution of the machine before the rinsing phase. Therefore, it is desirable to gradually suppress foaming over time.

Therefore, it is necessary to produce foam early in the washing process, such as when the composition detergent comes into contact with water for the first time, as well as a foam suppressor component to control the foam after Your training

WO 93/01269 describes particles defoamers comprising an organic carrier material in form of particles, a specific silicone antifoam and a layer of covering.

None of the existing techniques provide All the advantages and benefits of the present invention.

Summary of the invention

This need is satisfied hereby. invention, which is directed to a foaming system controlled specially adapted for use in compositions detergents containing a foaming component capable to provide foaming or soaps without stirring, and a delayed release foam suppressor component conforming to claim 1. The present invention also relates to detergent compositions containing the formation system of controlled foam

These and other characteristics, aspects and advantages of the present invention will become apparent to the experts in the art with the reading of the present description and of the attached claims.

Detailed description of the invention

Although this specification concludes with claims that distinctively point out and in particular claim what is considered the invention, it is believed that the invention can be better understood by careful reading of the detailed description of the invention that follows. In this specification, all percentages, coefficients and proportions are by weight, all temperatures are expressed in degrees Celsius, molecular weights are average weights, and the decimal comes represented by the comma (,), unless otherwise indicated. The citation of any of the references does not imply an admission concerning no determination about its availability as state of the art for the claimed invention.

In the manner used in the present invention, "comprising" means that other steps can be added and other ingredients that do not affect the final result. That term encompasses the terms "consisting of" and "which essentially consists in".

In the manner used in the present invention, the term "alkyl" means a linear hydrocarbyl moiety or branched, saturated or unsaturated. Unless another one is specified thing, the alkyl moieties are preferably saturated or unsaturated with double bonds, preferably with one or two double bonds. Included in the term "alkyl" is the alkyl portion of the acyl groups.

The present invention is directed to a system of controlled foam formation specially adapted for use in detergent compositions containing a forming component foam capable of providing foam or soap information without stirring, and a foam release suppressor component delayed The delayed release foam suppressor component It is a silicone foam suppressing agent that is incorporated by release in a vehicle, thereby delaying the release of silicone foam suppressing agent.

When the foaming system controlled comes into contact with water for the first time, the Foaming component generates foam quickly and stable without stirring. When used in the present invention, the term "foaming" means any form of gas bubble formation, including soap formation and effervescence. Stirring is not necessary, but it can improve foam generation, so it may be preferable. Preferably, the foaming component produces the contact with water, gas bubbles with a particle size of average bubble of 400 micrometers or less, preferably 200 micrometers or less, and more preferably 100 micrometers or less.

After foaming, the component delayed release foam suppressor is released over time, suppressing or controlling foam formation or controlling this otherwise reducing the amount of foam. According to when the foam should be removed, the time interval can adjust by choosing the type of foam suppressor component suitable. For example, for some machine wash conditions, foam suppressor component reduces water gas bubbles as early as at the time of agitation, so that preferably after 120 seconds, the bubbles have reduced by at least 30%. Also, for example, in some others machine wash conditions, after 360 seconds at 600 seconds, the bubbles have been reduced to a percentage of 40 to a 70%, or otherwise substantially suppressed before the stage of cleared up.

Preferably for washing conditions a machine, the foam suppressor component may not reduce the Water gas bubbles in the initial stages of washing, put It may be preferable to maintain the amount of foam for a longer period of time.

In a preferred embodiment, the component of Foaming and release foam suppressor component delayed are independent dry particles. The term "dry" should be understood as that particles of matter premiums are substantially free of water, that is, it has not been added water other than moisture from the same raw materials. From Typically, the water level is below 5% by weight of the total particle, preferably below 3% and more preferably below 1.5%.

For example in a detergent composition, such as a granular detergent composition, the final composition it contains a mixture of the two types of particles in addition to others conventional detersive components. In another embodiment preferred, one of the particles is present as part of another conventional detersive component. Having separate particles is particularly useful because you can control the different levels, thus providing a controlled supply of foaming component and suppression component at washing process, that is, one more supply can be achieved Efficient and on time, to provide optimal performance.

Although you do not want to be limited by the theory, it is believed that a detergent composition that has a system controlled foam formation, especially in the phases Early in the wash cycle, it has cleaning advantages. By For example, it is believed that the foam helps transfer the surfactant into the detergent composition to the stain to be removed and / or in the tissue. In addition, the foam is believed to help moisten and dissolve additional detergent composition. In addition, it is believed that the foam provides an early reserve of non-surfactant precipitate to moisten the tissues and that helps to suspend the dirt in the wash solution.

The controlled foam formation system It is also stable to storage. For example, the components do not degrade during storage while being exposed to air humidity In addition, because the training component of foam contains an effervescent granule, incorporating the controlled foam formation system in a composition detergent improves the dissolution characteristics of active ingredients present in the detergent composition.

Another advantage of the present invention is that of the improved dispensing characteristics associated with the detergent compositions of the present invention, for example, detergent compositions intended for use in a washing machine drum clothes In fact, a difficulty encountered with conventional high density granular detergent compositions is that they do not drag easily from the dispenser drawer of a washing machine: that is, when the granular composition becomes wet through the water flowing through the dispenser, the detergent ingredients can adhere to each other giving rise to considerable residues of moistened and adhered powder remaining in the drawer. Similar problems are observed when using these granular detergent compositions in a device dosage in the wash drum. The presence of the granule effervescent in granular detergent compositions provides an improved dispensing typically when used in a washing machine and good storage stability with respect to the potential of dispensed

B. Release foam suppressor component delayed

In the present invention an amount is used suds suppressor component foam suppressor delayed release The term "foam suppressor component of delayed release "means that the suppressor component of foam begins to suppress the foam after a while. Depending on when the foam should be removed, it can be adjusted the time interval choosing the appropriate type of component foam suppressor The term "suppressor amount of soaps "means that the formulator of the composition detergent has selected an amount of this component that will control the soaps in the desired magnitude. The amount of suppressor component will vary with the detergent component selected.

The release foam suppressor component Delayed is a silicone foam suppressor component. Saying silicone foam suppressor component contains an agent silicone foam regulator that has an average diameter of 1 to 50 micrometer droplet, incorporated by release into a water-soluble or water dispersible vehicle, practically not surfactant, detergent impermeable, and non-hydroscopic, being the substantially free silicone foam suppressor component of relatively hydroscopic and inorganic salts in the form of irregularly shaped particle with a minimum dimension of not less than 0.05 cm and with a maximum dimension at least 20% greater than the minimum dimension

The preferred suppressor component contains a silicone foam regulating agent that is practically isolated from the other detersive components of the composition Detergent. This "isolation" is achieved by incorporating the agent control in a water soluble organic vehicle matrix or dispersible in water. The matrix is a basically non-material non-hydroscopic surfactant that does not interact with the agent controller. In addition, the vehicle must be virtually impenetrable by detersive components to prevent interactions not desired silicone / detergent and / or silicone / alkalinity. Besides, the vehicle matrix in the present invention preferably not Contains added surfactants other than silicone. The vehicle is selected so that, when mixed with water, the matrix of the vehicle dissolves or disperses to release the regulatory agent from the silicone foam and that it performs its control function of soaps or foam.

The silicone materials used such as Preferred silicone foam regulating agents herein invention may be alkylated polysiloxane materials of various types, unique or in combination with various solid materials such as the silica aerogels and the xerogels and hydrophobic silicas of various types. In industrial practice, the term "silicone" has become a generic term that encompasses several polymers of relatively high molecular weight that they contain siloxane units and various hydrocarbyl groups types. Generally speaking, soaps controllers of silicone can be described as siloxanes that have the chain Main general structure.

where x goes from 20 to 2,000 and R y R 'are each of them alkyl or aryl groups, especially methyl, ethyl, propyl, butyl or phenyl. Polydimethylsiloxanes (R and R 'are methyl) which have a molecular weight within the range of 200 to 200,000, and higher, are all useful regulatory agents of foam. Silicone materials are marketed by Dow Corning Corporation under the trade name Silicone 200 Fluids®. Suitable polydimethylsiloxanes have a viscosity of 2 x 10-5 to 1.5 x 10-3 m 2 s -1 (20-1500 cs), at 25 ° C when It is used with silica and / or resin siloxane

Additionally, other silicone materials in where the side chain groups R and R 'are alkyl groups, aryl, or mixed alkyl and aryl hydrocarbyl exhibit properties Soap control tools. These materials are prepared easily by hydrolysis of alkyl, aryl or dichlorides of alkylaryl or aralkyl silicone mixed with water in the manner well known in the art. As specific examples of such silicone foam regulating agents useful herein invention can be mentioned, for example, diethylpolysiloxanes; dipropyl polysiloxanes; the dibutyl polysiloxanes; the methyl ethyl polysiloxanes; phenylmethyl polysiloxanes. Dimethyl polysiloxanes they are particularly useful in the present invention because of their low Cost and easy availability.

The "droplets" of silicone in the matrix of vehicle preferably have an average diameter of 1 to 50 µm, preferably 5 to 40 µm, more preferably 5 to 30 um for maximum efficiency. Droplets below 5 µm in diameter are not very effective and above 30 µm of Diameters are becoming less effective. Similar sizes are required for other silicone foam regulating agents described to continuation.

A second highly preferred type of agent silicone foam regulator useful in the present invention comprises a mixture of an alkylated siloxane of the type described above and solid silica. Such mixtures of silicone and silica can be prepared by attaching the silicone to the silica surface (SiO2), for example by means of the catalytic reaction described in US Pat. No. 3,235,509. The agents foam regulators comprising mixtures of silicone and silica prepared in this way preferably comprise silicone and silica in a silicone ratio: silica from 19: 1 to 1: 2, preferably from 10: 1 to 1: 1. Silica can be chemically bonded or physically to the silicone in an amount that is preferably of 5% to 20%, preferably 10 to 15%, by weight, based on the silicone. The particle size of the silica used in such Silica / silicone foam regulating agents should preferably be no more than about 1000, preferably no more than 100 nm, preferably 5 nm to 50 nm, more preferably from 10 to 20 nm, and the specific surface area of the silica should be greater than 5 m 2 / g., preferably more of 50 m 2 / g.

Alternatively, the regulatory agents of foam containing silicone and silica can be prepared by mixing a silicone fluid of the type described above with a silica hydrophobic with a particle size and surface area in the range described above. Any of the various methods can be used. known to make a hydrophobic silica that can be used in the present invention in combination with a silicone as agent foam regulator. For example, one can react smoked silica with a trialkylchlorosilane (i.e. "silanada") to fix hydrophobic trialkylsilane groups in the surface of the silica In a preferred and well known process, smoked silica is contacted with trimethylchlorosilane, preparing a silanated preferred hydrophobic silica useful in the present compositions.

In an alternative procedure, a silica hydrophobic useful in the present compositions is obtained by putting Contact the silica with any of the following compounds: metal, ammonium and long chain substituted ammonium salts fatty acids, such as sodium stearate, aluminum stearate, silylhalides, such as ethyltrichlorosilane, butyltrichlorosilane, tricyclohexylchlorosilane; and long chain alkylamines or salts of ammonium, such as cetyltrimethylamine and chloride cetyltrimethylammonium.

A preferred foam regulating agent in the The present invention comprises a silanated hydrophobic silica (with maximum preference trimethylsilanada) having a size of particle in the range of 10 nm to 20 nm and a specific area of surface area above 50 m 2 / g intimately mixed with a dimethyl silicone fluid having a molecular weight in the range from 500 to 200,000, with a silicone to silica weight ratio silanada from 10: 1 to 1: 2. Such foam regulating agents preferably they comprise silicone and the silica silanada in a silicone weight ratio: silica silica from 10: 1 to 1: 1. The hydrophobic silica silanada (especially trimethylsilanada) agents silicone foam regulators provide regulators of the foam in a wide range of temperatures, presumably due to the controlled release of silicone from the surface of the silica silanada.

Another type of foam regulating agent in the The present invention comprises a silicone material of the type described above adsorbed to, and in, a solid. Such agents foam regulators comprise silicone and solid in a silicone ratio: solid from 20: 1 to 1:20, preferably from 5: 1 to 1: 1. Examples of solid sorbents suitable for silicones in The present invention include clay, starch, earth diatoms, batan land. The alkalinity of solid sorbents does not affect the compositions in the present invention, since it is has discovered that silicones are stable when mixed with they. As described above, the sorbent plus the agent Silicone foam regulator should be coated or otherwise incorporated into a vehicle material of the type described below to effectively insulate the silicone of the detergent component of instant compositions.

Another type of foam regulating agent Preferred silicone in the present invention comprises a fluid of silicone, a silicone resin and silica. Silicone fluids useful in such regulating mixtures of soaps are of any of the types described above, but are preferably dimethyl silicones The silicone "resins" used in such compositions may be any alkylated resins of silicone, but they are usually those prepared from Methylsilanes Silicone resins are commonly described as "three-dimensional" polymers arising from the hydrolysis of alkyltrichlorosilanes, while silicone fluids are "two-dimensional" polymers prepared by the hydrolysis of dichlorosilanes. The silica components of such compositions are microporous materials such as smoked silica aerogels and the xerogels that have particle sizes and areas of surface described above.

The mixed fluid materials of silicone / silicone resin / silica useful herein compositions can be prepared in the manner described in the patent US 3,455,839. These mixed materials are marketed by Dow Corning Corporation. According to the patent US 3,455,839, such materials can be described as mixtures consisting basically of: per 100 parts by weight of a polydimethylsiloxane fluid having a viscosity in the range from 2 x 10-5 to 1.5 x 10-3 m 2 s -1 (20 cs. to 1500 cs.) at 25 ° C, (a) from 5 to 50, preferably 5 to 20, parts by weight of a siloxane resin composed of units (CH 3) 3 SiO 1/2 and of SiO_ {units} in which the proportion of the units (CH 3) 3 SiO 1/2 with respect to the units of SiO2 is within the range of 0.6 / 1 to 1.2 / 1; and (b) from 1 to 10, preferably 1 to 5, parts by weight of a solid silica gel, preferably an airgel.

Again, such foam regulating agents Mixed silicone / silicone resin / silica should be combined with a detergent impermeable vehicle material to be useful in Compositions in the present invention.

The silicone foam regulating agents of type above are preferably incorporated in (i.e. coated, encapsulated, covered by, internalized, or some another way basically contained in) a vehicle material basically water soluble or water dispersible and not hydroscopic, which must be impervious to detergents and alkalinity and that in itself must be virtually no surfactant. By virtually no surfactant it it means that the vehicle material itself does not interact with the silicone material so as to emulsify the material of silicone or otherwise disperse excessively before its release in the wash water. That is, the particle size of The silicone droplet should be kept above 1, plus preferably above 5 mm.

Of course, when preparing a composition dry or granulated powder detergent, it is preferable that the silicone foam regulator component of it also be basically dry and not sticky at room temperatures. So, it is preferred in the present invention to use as a material vehicle, or vehicle, plastic, organic compounds that can melt or mix conveniently with the regulating agent of the silicone foam, and then cool to form flakes solid. There is a wide variety of such vehicle materials useful in the present invention. Since the regulatory agent of silicone foam will be incorporated so that it can be released in the vehicle, so that the silicone is released in the bathroom aqueous at the time of mixing the composition, it is preferred that the vehicle material is water soluble. However, they are also useful water dispersible materials, since they also release the silicone at the time of its addition to an aqueous bath.

A wide variety of carrier materials are known that satisfy the solubility / dispersibility characteristics.
The essential characteristics of being practically non-surfactant, practically non-hydroscopic and practically impervious to detergents. However, polyethylene glycol (PEG), which has virtually no surfactant characteristics, is highly preferred in the present invention. A PEG with molecular weights of 1,500 to 100,000, preferably 3,000 to 20,000, more preferably 5,000 to 10,000 can be used.

Surprisingly, fatty alcohols very ethoxylates such as condensed tallow alcohol with at least 25 molar proportions of ethylene oxide are also useful in the present invention Other alcohol condensates containing extremely high proportions of ethoxylate (25 and more) too They are useful in the present invention. Such high ethoxylates lack seemingly sufficiently of surfactant characteristics to interact or otherwise interfere with the properties desired foam regulation of silicone agents in the present invention Various others can also be used. materials useful as vehicle agents in the present invention, e.g. eg, jelly; agar; gum arabic; and various gels derived from algae.

A highly preferred carrier material is a mixture from 0.2% to 15%, preferably from 0.25% to 5%, more preferably from 0.25% to 2% of fatty acids containing 12 to 30, preferably from 14 to 20, more preferably from 14 to 16, atoms Carbon and PEG balance. Such vehicle material provides a more desirable pattern of soaps for the duration of the washing process, providing more soapy needles at the beginning and less soaps at the end than PEG alone. Fatty acid retards the solubility of the antifoam particle and therefore delays the silicone release. Soap and / or wax can also be used instead of fatty acid.

The regulating component of silicone foam particle of preferred irregular size can be prepared so suitable in a highly preferred form of flake, mixing the silicone foam regulating agent with a carrier material molten, mixing to form the silicone drop size appropriate and forming the flakes, for example by crushing or extrusion to form a thin sheet, cooling to solidify the carrier material, and decomposing the particulate sheet of the appropriate size. In another preferred process, sheets may be formed. thin cooling molten vehicle material with antifoam scattered on it in, p. ex. a cooling laminator or refrigerator belt and subsequently decomposing said film into flakes of the right size. The thickness of the flake should be 0.05 to 0.15 cm, preferably 0.05 to 0.1 cm. When this is used procedure, the silicone foam regulating agent is contained in the vehicle material in such an effective manner that when this material is eventually mixed with, or incorporated into, a detergent composition, silicone practically does not enter contact with the surfactant detergent ingredient.

To obtain a foam regulator component granular, non-sticky useful in granular detergent compositions dried, the silicone foam regulating agent flake and the Vehicle material must be virtually solidified. This can achieved through the use of cooling belt coolers quickly leaves or flakes so that the vehicle hardens molten. Extrusion techniques can also be used.

It must be recognized that the amount of vehicle used to insulate the silicone foam regulating agent in the present invention of the detergent component of the Compositions in the present invention is not critical. It is only necessary to use a sufficient amount of vehicle to provide sufficient volume so that virtually all of the Silicone can be incorporated into it. Similarly, it is preferred have enough vehicle material to provide resistance enough to the resulting granule to resist premature breakage. Generally a weight ratio of more than 2: 1 is used, preferably from 5: 1 to 100: 1, more preferably from 20: 1 to 40: 1, from vehicle to silicone foam regulating agent.

The particle size of the component foam regulator used in the present compositions is select to be compatible with the rest of the composition Detergent. The foam regulating components herein invention are not segregated unacceptably in the composition Detergent. In general, particles with a maximum dimension of 600 to 2000, preferably 800 to 1600 µm are compatible with spray dried detergent granules. Therefore, the Most particles should have these maximum dimensions. Most particles should have a ratio of maximum to minimum diameter of 1.5: 1 to 5: 1, preferably 1.5: 1 to 4: 1.
