Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a synthetic organic detergent composition containing Pilgoo. More specifically, the present invention provides
y) ratio of polyacetal carboxylate builder for synthetic organic detergents. The invention also relates to a method for cleaning soiled textile materials, in which the composition or components thereof are utilized.

Synthetic organic detergent compositions used as anionic and/or nonionic detergents or detergent ingredients and in which organic or inorganic builder salts are present are among the six synthetic organic detergents that have been used commercially for a long time. In the past, anionic detergents were generally preferred;
Mixed anionic-nonionic products have also been successfully marketed. A variety of organic and inorganic builder salts have been included in commercial household laundry detergent compositions.

And of these, until very recently, sodium tripolyphosphate has been almost consistently the most preferred. Such polyphosphates are excellent builders that are consumer safe and reasonably priced, yet highly effective for their intended enhancing properties. Recently, however, phosphorus has been blamed for the contamination of inland waters due to eutrophication, and for that reason its use in detergent compositions has been suppressed, restricted, or even banned in various administrative authorities. . Efforts have therefore been made to produce detergent compositions that are both linen-based and yet effective heavy-duty detergents.

Among the specific phosphorus compounds that have been suggested for use as builders in detergent compositions are polyacetal carboxylates. Such compounds have been described in various US and foreign patents, including US patents! PJ4,144゜226 (Monsanto Company) and PJ4,146,495 (Monsanto Company)
Usually, according to the patent, the molecular weight of the substance is 1°000.
~40,000 or more, preferably 1,000-20.0
00, more feminine would be between 5,000 and 10,000. However, the anionic and nonionic synthetic detergents and polyacetal carboxylates of the present invention have been disclosed in the prior art as components of detergent compositions. However, the use of combinations with polyacetal carboxylates in a relatively narrow range has been implicated and unclear. Such compositions of undeveloped November exhibit improved cleaning action, difficult-to-remove properties during cold water washing in medium hardness water, compared to similar compositions containing high molecular weight polyacetal carboxylates. It shows good removal of dirt and stains and is also superior to the control composition using polyphosphate builder instead of polyacetal carboxylate.

According to the invention, in particular 50 to 1 as calcium carbonate
Built-in synthetic organic detergent compositions useful for laundering in cold water with hardness in the 50 ppm range include 5 to 30% anionic synthetic organic detergents and nonionic synthetic organic detergents and mixtures thereof. a synthetic organic detergent selected from the group consisting of, said detergent containing at least one ethoxy group/molecule; a polyacetal carboxylate builder of 5 to 95%, said builder having 3.0
and the remainder, if present, of one or more auxiliaries and/or fillers and/or diluents. Preferably, the anionic organic detergent is a sulfurized higher aliphatic alcohol ethoxylate, and the nonionic organic detergent is a condensation product of ethylene oxide and a higher aliphatic alcohol. Although granular detergent compositions are preferred, the compositions may be of other types, e.g.
), cakes, liquids, pastes and powders. When preparing granular products, various methods can be used, such as spray drying, spray cooling, agglomeration, granulation, milling and compaction.

It is also within the scope of the present invention to use said composition to wash soiled textile materials in hardness water ranging from 50 to 150 ppm at temperatures ranging from 10 to 70°C, preferably from 10 to 30"C. Further, a method of washing laundry with the synthetic organic detergent component and the acetal carboxylate component of the composition is part of the present invention.

Although cationic detergents and/or amphoteric detergents can be included in the relatively uninvented compositions, they are
If f4 is used, it will normally be limited to a total of 10%, and preferably less than 5%. The principal detergents used according to the invention are anionic and/or nonionic. Among anionic detergents, sulfated and/or sulfonated lipophilic materials having 8 to 20 carbon atoms, preferably 10 to 18 carbon atoms, more preferably 12 to 16 carbon atoms Select.

Various water-soluble salt-forming cations, such as ammonium and lower alkanolamines (e.g., triethanolamine) can be used to form the desired soluble [M- and sulfonated detergents, usually alkali metals. For example, sodium or potassium is used, and very preferably such cation is sodium.

Among the various anionic detergents useful in the practice of this invention, linear higher alkylbenzene sulfonates, monoglyceride sulfates, higher aliphatic alcohol sulfates, paraffin sulfonates, and olefin sulfonates are useful in the practice of this invention. In all of the above compounds, the alkyl (or ary-root for monoglyceride sulfate) present will be in the range of 10 or 12 to 18 carbon atoms.

Some of the alkyls may be slightly branched, but still have carbon chain lengths within the desired range, and the anionic detergents described above are useful in the practice of this invention. In combination with polyacetal sulfoxylate hildar, those considered to be most useful and effective are anionic detergents containing ethoxy groups. Most preferred among these are sulfated polyethoxylated higher alkanols which can be synthetic or organic and have a content of 3 to 20 or 30 ethoxy groups per mole. Preferably, the detergent is an alkali metal salt, such as a sodium salt, and the higher alcohol is 12-18
carbon atoms, and the detergent contains ethoxy groups in a proportion of 3 to 12, preferably 3 to 7, for example 3 or 5 mol per mol.

Nonionic detergents can be used as primary detergents in place of anionic detergents, or can be used together with anionic detergents, preferably to clean solid materials (especially solids) under normal conditions. or when incorporated into a granular product), and T t L < is the condensation product of ethylene oxide and higher aliphatic alcohol;
Higher aliphatic alcohols usually have 10 to 10 carbon atoms, Or
Preferably an average of 12 to 15 carbon atoms, e.g. about 12
~13 carbon atoms, and the content of ethylene oxide is 3 to 20 mol per mol of aliphatic alcohol,
Preferably 3 to 12 moles, more preferably 5 to 9 moles, for example #y6.5 or 7 moles of ethylene oxide. Examples of other nonionic detergents that are also useful are ethylene oxide condensation products of alkylphenols having 5 to 12 carbon atoms in the alkyl group, such as /nylphenol, where the ethylene oxide content is 3 to 12. 30 moles is 1 mole. Additionally, condensation products of ethylene oxide and propylene oxide, e.g.

Sold under the trademark Pluronic ■.

As well as other non-ionic detergents of the well-known group can be used, where aliphatic groups such as higher alkyls, alkylphenyls, polyoxy-lower alkylenes such as polyoxypropylene to polyoxyethylene ethanol can be used. Bonded by reaction with ethylene oxide.

Polyacetal carboxylates are disclosed in U.S. Patent No. 4,1
No. 44,226 can be considered and can be manufactured by the methods described therein. A typical such /l-substrate would have the formula R+-(CHO)n-1(*OOM where M is an alkali metal, ammonium, 1 to 4 carbon atoms alkyl groups, tetraalkyl ammonyl groups, and alkanolamine groups (both having 1 to 4 carbon atoms in the alkyl moiety), n is on average at least 6, and R1 and R2 are alkaline Any chemically stable group that stabilizes the polymer against rapid depolymerization in solution. Preferably, the polyacetal carboxylate is M or an alkali metal, e.g.

6,000. Preferably 4°000-s, ooo, more preferably 4,500-5.500, e.g.
It is 250.

Preferred polyacetal carboxylates are those mentioned above or, if they have the same molecular weight, as described in various patents of MOnsanto Co., Ltd. for said compounds, methods of making said compounds, and compositions. Other such polyacetal carboxylates or related organic builder salts may be substituted, completely or partially, at least in part. The various patents mentioned above, especially U.S. Patent No. 4.1.
44,226 can be utilized, provided they have the desired stabilizing properties, depolymerize the aforementioned builders in an acidic medium, and are or maintain their stability in alkaline waxes, such as cleaning solutions.

Although other builders other than polyacetal carboxylates may be present in the compositions of the invention,
Since this is not necessary and it is often desirable to avoid the presence of phosphorus in detergent compositions, polyphosphates (particularly pentansodium tripolyphosphate) are the builders of choice in the detergent sector for many years. Preferably, they are excluded from the formulations of the invention. Note that in some cases they may be present at least in a relatively small proportion, for example up to 5% or 10%. Polyphosphates, such as 1 sodium 1. ) Among builders other than lipolyphosphate, tetranatrium, and pyrophosphate, the enhancing effect of polyacetal carboxylate (buildin

If necessary, it can be present to increase the amount of product. In liquid compositions, the composition should normally be used immediately after preparation and may contain diluents such as soluble V, dispersants, bulking agents and antifreeze agents, as well as adjuvants, thickeners and stabilizers. It is possible to make it exist. Common milling agents include water, ethanol, impropatol and propylene glycol, and adjuvants include gums, clays, polymers and salts.

For example, it is known that sodium carbonate and water are often present together with polyacetal carboxylates in Hilder U, which is the source of the polyacetal carboxylates of the present invention.

Moisture will normally be present in the solid (including particulate) compositions of the present invention as l6irII moisture or in the form of one or more hydrates. Moisture is not an essential component of these improved formulations. It is usually present because of the use of water in manufacturing and, as is usually desired, solubilizes the other components of the composition and

It has a calculated weight average molecular weight of 0 and 3.9% sodium carbonate), with the remainder being mostly water.

The ratio of synthetic organic detergent to polyacetal carboxylate is from 1:10 to 2:1, preferably from 1.50 to 1:1, more preferably from 1:3 to 4:5, for example 5:8. Although said ratio includes detergents other than those containing at least one ethoxy/molecule, said detergents, if present,
It will be only a small portion of the total detergent, preferably less than 115, more preferably less than 1/10.

In addition to the one or more synthetic organic detergents and the sodium polyacetal carboxylate, other components of the compositions of the invention include one or more other "builders and/or fillers and/or solvents and and/or diluents and/or dispersants and/or adjuvants. Technically, detergents and polyacetal carboxylates are the only necessary ingredients of the invention in the broadest sense, although conventional ingredients may also be present due to their supportive properties. The auxiliary builder substances that may be present are usually limited to 50%, preferably 2 or 3 to 40%,
Examples of more preferred auxiliary builders, more preferably from 5 to 30%, are sodium carbonate, g1 sodium carbonate, zeolite A (but other zeolites can also be used), 1.°1.6 to 1:3. O1 preferably in the range of 1:2.0 to 1:2.6 (7) Na2O:Si

%, and the amount of sodium silicate is more preferably 3-12%. If polyphosphate is present, its proportion will preferably be limited to 10% or less.

The content of fillers in the formulations of the invention is usually above 70%, preferably in the range 10-60%, more preferably 10-40%. The filler is usually sodium sulfate, but it can also contain a small proportion, less than half, of other filler materials, such as sodium chloride.

The total amount of adjuvants in the compositions of the present invention is usually not more than 20%, preferably not more than 10%.

bleaching substances 1 (for example, when using sodium perborate, it can constitute up to about 30% of the product), and preferably the total auxiliary content is less than 5%, with the individual auxiliary The content generally does not exceed 3% or 5% and preferably individually less than 1 or 2%. Thus, if a high-grade (10-18 carbon atoms) sodium soap is present, it may be desirable to use it at 1-4% (due to its foam-reducing properties), and When using sodium carboxymethylcellulose (as an anti-redeposition agent), the ratio is 0.
It can range from 3 to 3%, preferably about 1%. In liquid preparations, highly porous silica, such as that sold under the tradename Cab-0-Sit, is used in a proportion of 0.5 to 5% to suspend the polyacetal carboxylate. and 1-5% of one or more hydrotropes, such as sodium xylene sulfonate, may be present to promote physical stability and homogeneity of the product. The moisture content of the products of the invention is usually between 3 and 20% for solid or granular products, preferably between 5 and 15%, more preferably between 5 and 12%, and between 20 and 12% for liquids.

The percentage of co-solvents (e.g. ethanol), if present, will typically range from 2 to 30%, preferably from 5 to 20%, to facilitate solubilizing the components of the composition. and can be used to adjust the viscosity of the product.

The preparation of the compositions of the invention can be carried out in any suitable conventional manner, whether to produce solid or liquid products. For liquid products, the diluent (solvent or dispersant) can have various ingredients added to it, usually preferably a hydrotrope or other dispersant, of the polyacetal carboxylate and any other insoluble materials present. Therefore, when mixing various components, it is present in a liquid medium. Mixing can be sequential or simultaneous, with sequential mixing being commonly used. The order of addition is usually not critical, but usually the color and flavor will be mixed near the end of the procedure. Also, viscosity modifiers are often added after other ingredients. In some cases, it may be desirable to retain some of the solvent for the final addition, so that the final dilution of the mixture can be carried out, when required, using mixers of various types. The use of a homogenizing mixer is preferred in such cases. Instead of a liquid with a viscosity in the readily flowable range that can be dispensed through the narrow neck of a bottle in a practical manner, a non-flowing paste can be produced, which usually contains a large proportion of thickener and It will contain a small proportion of solvent or diluent.

Particle Size in the Range of No. 8-120 or 10-100 Sieve To create the preferred particulate solid composition, spray dry as much of the formulation as possible to form small spherical particles of substantially uniform shape. It is often preferable to obtain Since the polyacetal carboxylates of the compositions of the present invention can be adversely affected by heat, the polyacetal carboxylates of the polyacetal carboxylates, which have been previously spray dried and formed into what may be called "base" beads, are It may be desirable to post-add the rate. If the polyacetal carboxylate is post-added, it will preferably have essentially the same shape, particle size and similar density as the rest of the composition to prevent segregation during transportation and storage. However, finer powdered polyacetal carboxylates, e.g.
Even when using polyacetal carboxylates with particle sizes in the range of ~200 or 325 meshes (or sieve numbers), such particles often adhere to larger beads, keeping the product within the desired size range. and was found to be essentially non-segregating (though of course the results would not be as good in this regard as when the various components of the composition were of similar size, shape and bulk density) .

When spray drying polyacetal carboxylates with detergent compositions, care is taken to prevent degradation of the polyacetal carboxylates due to exposure to the high temperature drying air of the spray tower. When spray drying is not effective or when cost is to be minimized, the various components of the compositions of the present invention can be prepared as powders. can be mixed together and agglomerated to the desired 10-100 sieve size;
Or they are usually 100.160 or 200~
It can be mixed together as a fine powder in the range of 325 mesh. When the non-ionic detergent is to be present in a unique proportion in the product, the main proportion can be post-sprayed onto previously spray-dried beads or onto particles of other components of the composition. I can do it. Typically, based on the final product, more than about 4% of the nonionic detergent will not be present in the spray dried product. Unless added after spray drying, nonionic detergents can decompose at high column temperatures when more than a relatively small proportion is present in the crutcher slurry being spray dried. Other temperature-sensitive components of the product are similarly post-added to avoid undesirable exposure to high temperatures. Thus, if bleach 1, for example sodium perborate, is present in the formulation, it is added afterward, as are enzyme powders, fragrances and other heat-sensitive ingredients. In contrast, inorganic builders, such as sodium carbonate, sodium bicarbonate, sodium silica and zeolites, and fillers, such as! Sodium acid is strong;
They promote the formation of attractive, free-flowing, spray-dried beads and are preferably incorporated into the clarification slurry to be dried and sprayed for their physical properties as well as their strengthening and filling functions. There will be.

Soiled (and contaminated) textile materials, e.g. cotton,
polyester-cotton blend, polyester, acrylic,
In the practice of the cleaning method of the invention, ordinary fabrics and "laundry" fabrics of nylon, acetate, rayon and various blends thereof are washed in an aqueous cleaning medium.
The medium will contain a suitable detergent and a polyacetal carboxylate of the desired calculated weight average molecular weight, as described. Preferably, such ingredients will be part of the detergent composition, but it is also within the scope of the present invention to provide said materials separately to the wash water.Improvements in the cleaning action of the preferred non-ionic detergents described above also fall within the scope of the present invention. With the described composition based on the compositions described, it is possible to obtain at intermediate or moderate water hardness and also during high hardness, during both cold and hot water washing, but the most significant in such cases Improvements are obtained when the washing water is of medium hardness. Also, when the detergent is a preferred anionic detergent, the most significant improvement is obtained with cold water washes using medium water, and cold water washes with high hardness water also improve, but to a lesser extent. not big. Thus, the preferred conditions for cleaning with the compositions of the present invention are medium hardness (as calcium carbonate 50-150 ppm) in cold water (10-30°C). Such preferences also apply when the active ingredients are used and added separately to the wash water in automatic washing machines. Moreover, in many cases the wash water has a high hardness, e.g. 150 or 200-3
00 or 400 ppm and at elevated temperatures, often up to 70'C.

Preferably, the wash n1 is carried out using the composition of the invention and from 0.05 to 0.5%, more preferably from 0.1 to 0.5%.
0.3% of the composition is used, most preferably about 0.15%. Washing water used is 0.0025-0.15%
of synthetic organic detergent and 0.0025-0.475% polyacetylene carboxylate. The preferable range of each of the above substances is 0.005 to 0.0.
075% and 0.01-0.15%, and at 0.15% of the composition, the preferred proportions of detergent and polyacetal carboxylate are each about 0.02
25% and about 0.0375%, the water used preferably has a hardness of 50 to 150 ppm and a hardness of 10 to 7
0°C, preferably in the range of 10-30°C, for example 21°C
temperature. The water hardness is more preferably about 1100 pp calcium carbonate (usually the calcium to magnesium ratio is 1:1 to 10:1, e.g. 3.2 to 4
: within the range of 1).

Under the conditions described, improved cleaning is obtained using the preferred anionic and/or cationic detergents of the present invention in conjunction with the low molecular weight polyacetal carboxylates described. When low molecular weight polyacetal carboxylate is replaced in the composition by a similar material but with a higher min-r content (8034), cleaning is significantly inferior in cold water washing in medium hardness water. Other detergents other than those taught herein as preferred when used with the polyacetal carboxylates of the invention described.

The results obtained are significantly inferior to those using the preferred detergents with the polyacetal carboxylates mentioned above.Also, with the other detergents, the polyacetal carboxylates of the polymeric gutter are slightly less than the lower molecular weight polyacetal carboxylates. was observed to appear to be effective, which is contrary to the results observed for the compositions of the present invention.Also, one of the standard and preferred builders of the prior art in place of the builder of the present invention When using sodium tripolyphosphate, the cleaning results are significantly inferior to those of the present invention.

The invention is further illustrated by the following examples.
