Description

[Detailed description of the invention] liquid detergent composition A type of liquid detergent in which the agent active structure is present as a separate phase dispersed within the filtrate phase. The present invention relates to a composition. This aqueous phase generally contains dissolved electrolytes. Special In addition, the present invention provides a liquid detergent active structure containing significant levels of non-ionic detergent components. The present invention relates to a body composition.

The present invention provides an "internal structure" in that the structure is formed primarily of detergent active ingredients. The present invention relates to a structured liquid detergent composition.

This type of structuring is well known in the art and, for example, provides consumer-friendly flow properties and This is done on purpose to contribute to properties such as a cloudy and/or cloudy appearance. Many Many detergent active structuring fluids can be Particulate solids can also be suspended.

The various different types of detergent active structuring that are possible are described in the publication [H, A, Bar +u3'Dejetgea+s'', Ch, ii, in K, Wtlters (εd).

Lerchvar (h19N).In general, systems of this type are aligned The degree to which this occurs increases with increasing surfactant concentration and/or electrolyte concentration.

At very low concentrations, the surfactant is present as a solution of single molecules or as a solution of spherical micelles. Both of these are isotropic. In addition, surfactant Addition of electrolyte and/or electrolyte results in a structured (anisotropic) system. this They each have various names, such as rod micelles, planar lamellar structures, and lamellar structures. called droplets and liquid crystalline phases.

Different researchers often refer to detergent active constructs that are actually the same as different Name is used. For example, European patent EP-A-151!184 The lamellar droplets are called "spherulites". Surface activity in liquids The presence and identification of sex agent structured systems can be determined by means known to those skilled in the art, such as optical techniques. , various rheological measurements, X-ray or neutron diffraction and often electron microscopy. You can decide.

The electrolyte can be dissolved only in the aqueous continuous phase, or it can exist as suspended solid particles. It is also possible to exist. Particles of solid substances that are insoluble in the aqueous phase are used as solid electrolyte particles. They can also be suspended in place of or in addition to the particles.

Three common product forms of this type are liquid and liquid abrasives for heavy-duty fabric washing; It is also a general purpose cleaner. In the first type, the suspended facepiece is connected to the dissolved electrolyte and the real Consisting of qualitatively identical suspended solids present in excess of the solubility limit Can be done. This solid is commonly present as detergent buildup, i.e. in laundry liquids. Calcium ions antagonize the effects of water hardness.

In the second type, the suspended solids consist of particulate abrasives that are generally insoluble in the system. . In this case, the electrolyte contributes to the structuring of the active ingredient from the abrasive compound, so exists in However, in some cases, the abrasive may consist of partially soluble salts. , which dissolves when the product is diluted. In the third type, the structure is Generally used to thicken the product to give the consumer favorable flow characteristics, and sometimes Used to suspend pigment particles.

) Ill type compositions are described, for example, in European patent EP-A- No. 38,101, and an example belonging to the second type is provided to the applicant. It is described in European Patent EP-1t14.40. third type For example, US Patent No. 4. ! ! 44. ! Described in Publication No. 140 There is.

It has an onion-like structure consisting of two concentric layers of substance molecules, with water (aqueous phase) intervening between them. It seems to be that. Such structures of detergent actives are often called lamellar droplets. Ru. The close packing of these droplets seems to keep the solid material in suspension. Droplets can form themselves. Lamellar droplet systems may generally be present in detergent solutions. This is the preferred type of structure.

Preferably, the amount of viscosity-modifying polymer is between 0.1 and 5% by weight, based on the total composition. The content is preferably 0.2 to 2%.

In many cases it is preferred that the aqueous continuous phase contains dissolved electrolyte. used here The term electrolyte refers to ionic water-soluble substances. However, lamellar droplets In the dispersion of electrolytes, not all of the electrolyte is necessarily dissolved; It may be suspended as a child. This is because the total electrolyte concentration of the liquid is This is because it is higher than the solubility limit. A mixture of electrolytes, one or more of them. the upper one is present in the dissolved aqueous phase and one or more are present substantially only in the suspended solid phase It can also be used like this. two or more types of electrolytes between these two phases. It can also be distributed approximately proportionally. In part, this is a processing process, Depends on the order of addition of the minutes. On the other hand, the term "salt" can be used even in ionic form. also includes all organic and inorganic substances contained other than surfactants and water; Nago means soluble substance.

The only limit on the total amount of detergent actives and electrolytes (if present) is These do not form an aqueous lamellar carpet in lamellar droplet compositions included in It is a must.

That is, within the scope of the present invention, extreme variations in the type and amount of surfactant A wide range of changes are possible. surface to obtain a stable liquid containing the desired structure. The selection of the type of active agent and its proportions is well known to those skilled in the art. however An important class of useful compositions is that the detergent active is a mixture of different types of surfactants. It can be said that it is made of a compound.

In the case of mixtures of surfactants, the precision of each component to provide this kind of stability and viscosity The appropriate ratio depends on the type and amount of electrolyte, as in conventional detergent active structuring fluids. Depends on.

These compositions contain a sufficient amount to effect structuring of the detergent active as required. Contains electrolytes. Preferably the composition has a salting-out property of 1 to 60%, especially 10 to 45%. Contains electrolytes. Salting-out electrolytes are covered by European patent EP-A-79,64. No. 6, i.e. all electrolytes have a synergic number (li) of less than 9.5. oj+opicnall+bξr). Salt-soluble electrolysis of species as required (as defined in the Application Specification above), provided that this is compatible with the other ingredients. In addition, the composition should be determined according to the definition of electrolyte (salt-soluble or salting-out property). Substantially water-insoluble salts in accordance with or present in detergent formulations It can also have secondary characteristics. In any case, the composition according to the invention Preferably, the electrolyte contains an electrolyte, all or some of which is an electrolyte. Birgu – Substances can reduce the level of free calcium ions in laundry fluids , preferably e.g. generation of an alkaline pH, suspension of soils to be removed from the fabric, and imparting other advantageous properties to the composition such as dispersion of clay materials for fabric softening L especially alkali metal pyrophosphates, orthophosphates, polyphosphates and phosphonates includes.

Contains.

Electrolytes that promote the solubility of other electrolytes within the range of inorganic compounds, e.g. It is preferred to include a potassium salt which promotes the solubility of the um salt. This results in , the amount of dissolved electrolyte can be increased (UK Patent No. 1.3G2.543) ).

When organic detergents are present, e.g. alkali metals, ammonium and substituted ammonium polyacetates, carboxylates, polycarboxylates, poly Includes acetyl carboxylates and polyhydroxysulfonates. A specific example is Ethylenediaminetetraacetic acid, nitrilotriacetic acid, oxydisuccinic acid, CMO9 Sodium, potassium, melittic acid, benzene polycarboxylic acid and citric acid , including lithium, ammonium and substituted ammonium salts.

Preferably, the level of non-soap building material is between 0 and 50% by weight of the composition, such as The amount is preferably 2 to 40% by weight, particularly preferably 5 to 30% by weight.

Within the range of organic bilgoux, EP-LGI, [as described in No. 2, water It is particularly important to achieve buildability with polymers that are only partially soluble in the continuous phase. I can do it. This is because the undissolved portion will occur if substantially all of it dissolves. This is because it does not cause significant instability. Typical amounts are 0.5-4.5% by weight. Ru.

Furthermore, the compositions of the present invention contain water instead of or in addition to the partially dissolved polymer. Other polymers can also be included that are almost completely soluble in the phase; More than 5 g of sodium nitrilotriacetate in 100 d of 5% by weight aqueous solution of Rimer It has electrolyte resistance of 30%. This Yoiji polymer was further diluted with a 20% aqueous solution. 2% by weight or more aqueous solution of polyethylene glycol with an average molecular weight of 60H , and the second polymer has a molecular weight of at least 100+1.

The use of polymers of this type is generally described in EP 301,883 by the applicant. has been done.

Soluble polymer formulations offer improved physical stability at the same viscosity (soluble polymer ) or a composition with the same stability but lower viscosity. Allows to be prescribed. Additionally, soluble polymers have a viscosity drop as well as a decrease in viscosity. Lift can also be reduced. Here, improved stability and lower viscosity This means that the effect is higher than that produced by peptizing polymers.

Blending soluble polymers with partially soluble polymers that have large amounts of insoluble components It is particularly suitable to Because the build ability of partially dissolved polymer is good However, viscosity reduction is not optimal (because only a small amount can be blended stably). (does not dissolve). Thus, the soluble polymer brings the viscosity to a more ideal level. It can effectively act to lower the temperature to a level of For example, soluble polymer 0.05 -20% by weight, but generally 01-2.5% by weight of the total composition. Sufficient, especially 0.2 to 1.5% by weight. often higher levels causes instability.

Adding a small amount of hydroropel in addition to water-miscible solvents Preferably, the compositions of the present invention are substantially free of aqueous substances. Inside Aqueous substances are substances related to the solubility of surfactants in aqueous solutions.
