More particularly, this invention relates to phase separation and gelling stable and easily pourable non-aqueous liquid detergent compositions and methods of using these compositions for cleaning soiled fabrics.

For example, compositions of this type are described in US Pat.

These applications relate to non-aqueous liquid non-ionic detergent compositions.

Liquid detergents are often considered easier to use than dry powder or granular formulations, and are actually preferred by consumers. Liquid detergents are readily available, dissolve quickly in the water to be washed, can be easily applied as a concentrated solution or dispersion to soiled areas of clothing to be washed, and are dust-free. , usually requiring only small storage space.

Additionally, liquid detergents may also include in their composition materials that are often preferred for use in the manufacture of granular detergent products, but which cannot withstand drying operations without deterioration. Although liquid detergents have many advantages over single or granular solid products, they also often have certain inherent disadvantages that make it difficult to produce an acceptable detergent product. We must overcome this. Some products, such as foam, are difficult to foam and separate during storage, while others separate on cooling and are difficult to redisperse. In some cases, the product viscosity changes, becoming too thick and unpourable, or too dilute with a watery appearance. Some clear products become cloudy during storage, and some products become cloudy during storage.

The present invention relates to the study of the behavior of non-ionic liquid surfactant systems containing suspended particulate matter. Of particular concern are the settling problems of non-aqueous bilge-containing liquid laundry detergent compositions and suspended builders and other laundry additives, as well as the gelling problems associated with nonionic surfactants. These considerations have an impact on, for example, product stability, pourability, and dispensability.

One of the major problems with builder liquid detergent for washing
It is well known that one of the major factors is their physical stability. This problem arises from the fact that the density of solid particles dispersed in nonionic liquid surfactants is greater than the density of liquid surfactants.

Therefore, dispersed particles tend to settle.

There are 52 basic solutions to solve the settling problem: increasing the viscosity of the nonionic liquid and decreasing the particle size of the dispersed solid particles.

Add inorganic or organic thickeners or dispersants, such as very high surface area inorganic materials such as pulverulent silica, clays, organic thickeners such as cellulose ethers, acrylic polymers, acrylamide polymer polyelectrolytes, etc. It is well known that suspensions can be stabilized against sedimentation by temperature control.

However, such an increase in suspension viscosity would of course be limited by the requirement that the suspension be pourable and flowable even at low temperatures. Furthermore, such additives do not contribute to the cleaning performance of the composition.

Milling to reduce particle size provides the following benefits: 1. The wetting of the particles by the dispersing vehicle (non-ionic liquid) is correspondingly improved. 2. The average distance between dispersed particles is reduced. However, particle-particle interactions increase with stiffness. These effects contribute to increasing the static-gel strength and suspension yield stress, respectively, while comminution reduces the plastic viscosity.

Yield stress is defined as the minimum stress required to induce plastic deformation (flow) of the suspension. Nucleons dispersed in suspension 0
) When the applied stress is lower than the yield stress, the suspension behaves like an elastic gel and no plastic flow (10) occurs.Once the yield stress is exceeded, , this network breaks in some places and the sample begins to flow, but the apparent viscosity (or very high).If the shear stress is much higher than the yield stress, some of the pigment will Thus, the apparent viscosity decreases.Finally, if the shear stress is much higher than the yield stress value, the dispersed particles will completely shear-unravel and the apparent viscosity will become very low and the particles will not interact with each other. It's as if it has no effect at all.

Therefore, the higher the yield stress of the suspension, the higher the apparent viscosity at low shear rates and the better the physical stability of the product against settling.

Non-aqueous laundry detergents based on liquid non-ionic surfactants have problems with sedimentation or phase separation, as well as the fact that non-ionic surfactants have difficulty producing stable foam and tend to gel when added to cold water. It has the disadvantage that there is This problem,
This problem is particularly important in the normal use of European domestic automatic washing machines, in which the user dispenses washing detergent compositions into the machine's dispenser (e.g., dispensing case).

During washing machine operation, the detergent in the dispenser is exposed to a stream of cold water which transfers the detergent into the main body of the washing solution. Particularly during the winter months when the detergent composition and the grate water supplied to the distributor are very cold, the particle size of the detergent increases significantly and gels form. As a result, some of the detergent may not be completely flushed from the dispenser during machine operation, and deposits of the composition may form over repeated wash cycles, and in some cases the user may have to remove the dispenser with hot water. You will need to wash it off.

Gelling phenomena also become a problem when it is desired to wash with cold water, as is undesirable for certain synthetic delicate fabrics which shrink in hot or hot water.

The tendency of concentrated detergent compositions to gel during storage is enhanced by storing the compositions in unheated storage areas or by transporting the compositions in unheated vehicles during the winter months. Partial solutions to the gelling problem in substantially builder-free aqueous compositions have been proposed, including, for example, replacing liquid nonionic surfactants with lower alkanols such as ethyl alcohol. (
(see U.S. Pat. No. 2,953,380); alkali metal formates and adipates (U.S. Pat. No. 4,398,14);

In a preferred embodiment of the invention, the detergent composition comprises a fullkylene glycol monoalkyl ether and a phosphate alkanol ester antisedimentation stabilizer. Anti-gelling agents in acid-terminated nonionic surfactants, such as those disclosed in commonly assigned patent application Ser. It should not be added to the composition as it forms with the ions calcium salts which are suds suppressants.

Disinfectants or bleaching agents and bleach activators can be added to improve the bleaching and cleaning properties of the composition.

In one embodiment of the invention, the builder component of the composition is
Grinding to a particle size of less than 0 microns, preferably less than 40 microns, can further improve the stability of suspensions of builder components in liquid non-ionic surfactant detergents.

Viscosity control for nonionic surfactants - Adding an effective amount of a low molecular weight rephilic compound to a detergent composition to serve as an antigelation agent substantially improves the shelf life of the composition. Viscosity-modifying anti-gelling agents help lower the gel formation temperature when nonionic surfactants are added to water. Such viscosity-modifying antigelling agents are, for example, low molecular weight alkylene oxide lower monoalkyl ether amphiphiles. Amphiphilic compounds are believed to have the same chemical structure as ethoxylated and/or propoxylated fatty alcohol liquid nonionic surfactants, but with relatively short hydrocarbon chains (C2-C8) (31) and its ethylene oxide content is low (approximately 2 to 6 ethylene oxide groups per molecule). Suitable amphiphilic compounds have the following general formula: or methyl, n represents a number from about 1 to 6 on average].

Other suitable viscosity-modifying anti-gelling agents, supplied by Dow Chemical Company, that can be used in the present invention include Dowanol PIB-
T, which is a mixture of mono-, di- and tri-propylene dalicol monomethyl ethers.

The addition of low molecular weight lower alkylene dalicol monoalkyl ethers to the composition reduces the viscosity of the composition, making it easier to pour, improves sedimentation stability, and improves the stability of the composition when added to hot or cold water. Dispersibility is improved.

As set forth in commonly assigned co-pending patent application Ser. Acidic organophosphorus compounds with can enhance the stability of suspensions of builders in non-aqueous liquid non-ionic surfactants. Acidic organophosphorus compounds are, for example, partial esters of phosphoric acid and alcohols, such as lipophilic alkanols, having from 5 to 20 carbon atoms, for example from 8 to 20 carbon atoms.

A particular example is the partial ester of phosphoric acid and the 016-CI8 furcanol (EmpiphO8 5632 from Marchon Kara);
It is composed of approximately 35% monoesters and 65% diesters.

Very small amount of acidic organic phosphorus compound (e.g. 0.3% by weight)
When added, the suspension becomes sedimentary stable on standing but still pourable; the plastic viscosity of the suspension generally decreases for low concentrations of stabilizer.

Additions of more than about 0.3%, such as about 1.0% or more, should be avoided since high concentrations of organic phosphorus esters are believed to inhibit foaming.

Breaking down to less than microns, preferably less than 40 microns, more preferably less than 10 microns, improves the stability of the builder salt of the composition during storage and the dispersibility of the composition in water. Solid builders, such as sodium tripolyphosphate (TPP), are generally supplied in particle sizes of about 100.2004 to 400 microns.

A solid builder can be mixed into the non-ionic liquid surfactant phase before or after carrying out the milling operation.

G) In a preferred embodiment of the present invention, the mixture of liquid nonionic surfactant and solid component is placed in an attrition mill to reduce the particle size of the solid component to less than about 10 microns.
average particle size from 2 to less than 10 microns (e.g. 1
microns). It is preferred that less than about 10%, especially less than about 5%, of the total suspended particles have a particle size greater than 10 microns. (4) Compositions in which the dispersed particles have such a small particle size have improved phase separation stability or sedimentation stability during storage. The addition of acid-terminated nonionic surfactant compounds reduces the yield stress of such dispersions and helps improve the dispersibility of the dispersion without correspondingly compromising the sedimentation stability of the dispersion.

In the milling operation, the proportion of solids is such that the solid particles are in contact with each other and are not substantially shielded between the particles by the nonionic surfactant liquid (e.g., at least about
%, especially about 50%). After the milling step, remaining 0) liquid non-ionic surfactant can be added to the milled composition. Mills using grinding balls (ball mills) or similar movable grinding elements give very good results.
It's coming back. Therefore, a laboratory punch grinder with an 8-diameter steatite grinding ball could be used. For large-scale processing, 1 to 1.5
Continuously working mills (e.g. Co Ba1l mills) operating with 111J11 diameter grinding balls can be used;
If such a mill is used, the nonionic surfactant, solid ingredients, and blend may be first passed through a less fine grinding mill (e.g., a colloid mill) to reduce the particle size to 1.
Preferably, the particles are reduced by less than 0.00 microns, such as about 40 microns, followed by a milling step in a continuous ball mill to an average particle size of about 10 microns or less.

In the preferred heavy liquid laundry detergent compositions of the present invention, typical proportions of the ingredients (in % based on the total weight of the composition unless otherwise specified) are as follows: Liquid C9-CII Alkyl (CH2CH2O) 5OH nonionic surfactant detergent in the range of about 10-60%, preferably 20-60%, such as about 30-45% detergent builder (e.g. sodium tripolyphosphate) about 1
