Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides an improved textile product containing a detersively active surfactant mixed with a builder for use in washing textile products in an aqueous solution. Regarding detergent. In particular, the present invention seeks to further improve the environmental compatibility of active ingredient mixtures required for washing textiles.

[Prior Art] In the detergent industry, and in the chemical industry providing chemicals to the detergent industry, to improve the environmental problems associated with discharging used cleaning and cleaning solutions into waste water. Attempts have been made to redevelop the so-called builder systems necessary for the development and protection of the detersive power of surfactants, especially in hard water. In textile detergents commercially available in Europe, sodium trigylyphosphate (S T P), which in the past was almost the only builder, has been largely or completely replaced by sodium zeolites, especially the zeolite NaΔ. However, the quality of the washing process is closely related to the detergent-active surfactants used in detergent mixtures, which are present in various forms in the messy steps involved in washing. The surfactants most often used are mixtures of anionic and nonionic surfactants, significantly higher in quantity (the anionic surfactants used are alkylbenzene sulfonates (ABS or LAS), Examples of nonionic surfactants used in textile detergent mixtures include fatty alcohol polyethoxylates, which typically have short-chain polyglycol groups.Such surfactant mixtures are suitable for use in aqueous alkaline Their wetting power is high in the presence of builder systems in washing liquors.They are therefore an essential component of high-quality detergents, especially for textiles, due to their economical availability.

However, in recent years, on the basis of ecological data and, inter alia, the acute toxicity of widely used detergent-active surfactant compounds to aquatic organisms, the unrestricted use of textile formulations containing ABS or LΔS has been proposed. There is increasing criticism regarding. Multi-component washing machines developed in response to such criticisms can reduce the amount of surfactant, but only cover a small portion of the daily textile washing process.

OBJECTS OF THE INVENTION It is an object of the invention to eliminate the undesirable effects associated with the disposal of used laundry liquids by the use of a detersively active surfactant system with optimal environmental compatibility and, in particular, optimal acute toxicity to aquatic organisms. The aim is to further facilitate the disposal of used washing liquid, so that the effects are suppressed as much as possible. at the same time,
The present invention aims to maintain as much as possible the high detergency of current textile detergents. This means that in detergent testing, even in the complete or at least partial absence of the high wetting and high cleaning activity surfactants or surfactant systems commonly used in the past, current detergent primary It means that the detergency should reach or reach a high level.

[Structure of the Invention] The present invention relates to the use of di-salts of α-sulfonated fatty acids having 10 to 22 carbon atoms, preferably 14 to 18 carbon atoms, especially tallow fatty acids (
Based on the fact that the sodium di-salt (C,, -C,,) was found to have ecologically optimal properties (.

For example, acute toxicity tests on fish (Boltoffen (
Goldorfen), 48 hours), ABS or LA'S LC, value is 3.2 to 4.9 m? /12
It is. For daphnia (24 hours), 8°9-1

It is clear that compounds of this type are suitable as ingredients in detergents such as those mentioned above.

However, tests of the cleaning action of such sodium di-salts of α-sulfo fatty acids (hereinafter referred to as "sodium di-salts") have shown that 1% as a standard detergent mixture on standard soiled test textile products. Next, as a result of the measurement of detergency, it was found that the action as a detersive surfactant was very weak. Although detergency has been shown to be obtained by these sodium disalts, they have been shown to be unsuitable for practical use as a surfactant component or as the main surfactant component. Conceivable.

In the preparation of surfactants of a similar type, namely the sodium salts of α-sulfo fatty acid methyl esters,
It has been repeatedly pointed out in the relevant literature that the sodium disalt content formed by ester decomposition in such surfactants should be kept as low as possible. It is believed that this undesirable structure and solubility ratio of the sodium disalt results in its poor surface activity.

Tallow fatty acids with good detergency, especially C16-C5,
Sodium di-salts of fatty acids have poor solubility and are therefore considered unsuitable as detergent-active main surfactant components.

The use of di-salts in detergent mixtures has often been proposed in the past. West German Published Patents No. 2144592 and No. 2161726 contain, in addition to the usual detergent-active nonionic and/or anionic surfactant components, alkaline salts of α-sulfonated saturated fatty acids having 14 to 20 carbon atoms. Detergents for textile products are described. Such sodium di-salts are stated to be used alone as builders for surfactant components or in conjunction with conventional builder combinations consisting primarily of builder salts capable of complexing and/or precipitating calcium ions. has been done. Further improvements regarding the use of sodium di-salt as a builder component are described in EP 0070190 and EP 0070191. Therein, the sodium di-salt of an alpha-sulfonated carboxylic acid is used as co-builder with sodium zeolite as the main builder component in textile detergent mixtures consisting of standard surfactant mixtures. None of these proposals address the problems that the present invention seeks to solve (i.e., problems in the related surfactant field).
(Developing such sodium di-salts with favorable monomorphic properties for use as functionally important components of i-product detergents or as sole detergent-active surfactant components) I haven't.

The applicant's earlier patent application No. P3604039.8 includes:
Sodium di-salts as mentioned above, especially natural and/or
The use in detergents for textile products together with highly swellable fine particulate layered silicates selected from the group consisting of crystalline smectites or crystalline smectites with a synthetic highly swellable layered structure is described.

The aim is to impart improved, especially synergistically enhanced, softness to washed and dried textile products. It is contemplated to use in combination a surfactant selected from the group consisting of N1 fatty alcohol sulfates, alkyl glucosides, fatty N1 alkanolamides and/or ether amines. Again, there is no mention of the use of sodium di-salts as the sole or main surfactant component in textile detergent formulations in order to optimize the first wash results.

Japanese patent literature also describes the use of sodium disalts as surfactants or co-surfactants in textile detergents. For example, JP-A-60-18
No. 592 describes a bleaching detergent mixture containing (A) 1-15 tlIm% of an alkali di-salt of a sulfo-fatty acid as described above and (B) 3-15 tlIm% of sodium percarboxylate. It is contemplated to use in combination other surfactants and suitable builders as well as customary detergent components. AnS or LAS are mentioned as particularly suitable surfactants.

In addition to limited ff1 (4-10% by weight) sodium di-salt of α-sulfofatty acid methyl ester, multi-fft (
LAS or sodium α-olefin sulfonate (15 fft%) is used in the examples. JP-A-58-125849 discloses #a textile softener containing (A) 5 to 30ffff1% of an anionic surfactant and (B) 0.1 to 10% by weight of a quaternary ammonium compound. Detergents are listed. Surfactant component (A
) are stated to be selected primarily from alkali or alkaline earth salts of α-sulfo fatty acids and/or esters of α-sulfo fatty acids. It is contemplated to use other co-surfactants, especially ABS or LAS. Examples of such formulations are given in the Examples.

In addition to limited amounts of sodium di-salt, large amounts of LAS and/or alpha-sulfofatty acid methyl ester salts are present.

The technical teachings described below according to the present invention for solving the above problems have not been described directly or indirectly in related documents in the related art.

In order to achieve the desired objective of obtaining a high primary detergency using a surfactant consisting of said sodium di-salt, the present invention requires, on the one hand, adjusting the parameter of the Pu number in the composition of the detergent concentrate. On the one hand, and on the other hand, it is based on the surprising discovery that it is necessary to have a certain concentration of the detergent composition prepared according to the invention in the washing liquor.

Therefore, in its most general aspect, the present invention provides a method for enhancing the primary detergency of sodium di-salts of natural and/or synthetic alpha-sulfonated fatty acids having, inter alia, 10 to 22 carbon atoms. , sodium sulfate, sodium zeolite and/or sodium tripolyphosphate (S T P), optionally together with other alkalizing sodium alkaline builder ingredients for textile detergents ( (detergent concentrates) containing α-sulfonated fatty acid sodium di-salt as a detersive active surfactant component, sodium sulfate, sodium zeolite and/or S T +
1 Ut of the α-sulfonated fatty acid sodium di-salt contains at least about 20 III m% of 3, and the concentration of the di-salt in the washing liquid during use of the detergent is at least about 1 g/l, preferably at least about 1.5 g/2. Regarding detergents for textile products that are selected as follows.

The sodium di-salt content in the detergent concentrate is preferably such that when the concentrate is used, the sodium di-salt content in the laundry liquor is at least about 1.7 g/l, especially at least about 2 y/l.
1. The sodium disalt content in the washing liquid is about 1.7 to 3.5 g/l, especially about 2 to 39/1.
2, high primary cleaning power can be achieved.

Preferred sodium di-salts for use in the present invention are saturated C,4-C,@α-sulfo fatty acids, especially the corresponding C
1°-C1, derived from fatty acids or mixtures thereof.

Furthermore, the content of primary detergency-enhancing builders, namely sodium sulfate, sodium zeolite and/or STP, in the detergent concentrate is adjusted to at least about 25 fflm
%, especially at least about 30% by weight. A suitable builder content is, for example, about 30 to 80
ITIm%, preferably up to about 70ffflTt%. m is 1rim% based on the total weight of detergent concentrate
It is.

The present invention has surprisingly shown that using a textile detergent as described above containing sodium disalt as an active surfactant component, on the one hand, the disalt surfactant component content is relatively high in the wash liquor. This is based on the discovery that good primary detergency can be obtained when, on the other hand, the action is strengthened by the combined use of mineral builder components such as those mentioned above. Some notable findings related to this will be described in detail in Examples. As long as the above-mentioned sodium disalt is used as the cleaning active surfactant component, the surfactant content in the washing liquid is within the normal range (approximately 1.2y/ff
up to or at most about 1.5 y/(!), increasing the surfactant content does not significantly increase the primary detergency. In this case, even if the amount of builder ingredient is increased,
The primary cleaning power level does not increase much and does not reach the level of commercially available detergents. However, when the amount of active substance (AS) sodium di-salt in the washing liquid exceeds approximately 1.5 g/(2), the situation suddenly changes, and the primary cleaning power is optimized to improve the performance of standard high-quality textile detergents. In this respect, the presence of said mineral builder components plays an important role.In this context, electrolyte salts (e.g. sodium sulfate) are currently widely used in terms of their builder effect. It is surprising that the sodium disalt concentration in the washing liquor is substantially equivalent to that of the sodium zeolite (especially the crystalline sodium zeolite of the zeolite NaA type) used in the present invention. In high cases, sodium sulfate is also equivalent to STP in terms of builder effect.The mineral builder components mentioned above may be used alone or as a mixture of two or more;
In either case, the desired high primary cleaning power is achieved. That is, for example, sodium sulfate 10-45T [fff
i%, zeolite Na8 and/or STP about 20
It can be initially introduced into the detergent concentrate with ~40% by weight, preferably about 20-30% by weight. The washing results obtained in this case are as good as those obtained when using, for example, sodium sulfate or zeolite NaA as the sole mineral pilgu component, at a suitable dose of sodium di-salt within the range mentioned above. .

The content of sodium sulfate, sodium zeolite and/or STI' in the detergent concentrate is such that the content of those components which enhance the primary detergency is at least about 2y/(1, Especially 2-8y/(l
It is preferable to adjust it so that Approximately 2.5-6y
A content of /(l is particularly suitable.

The preferred content of sodium di-salt in the detergent concentrate is about 1
5 to 40% by weight, more preferably 15 to about 30%, with about 17 to 25% by weight being particularly suitable. Such detergent concentrates are suitable for preparing aqueous detergent solutions having a concentration of at least about 7.59 g/e, especially about 7.5 to 15 g/+2. A typical dosage of solid detergents as described above is about 1
09/1! on the order of, for example about 8-12y/
It is 2.

In addition to the sodium di-salt, the detergent concentrates and aqueous laundry liquors of the invention may contain other detergent-active surfactants or detergency-enhancing agents. In a preferred embodiment of the invention, the amount of such detergent co-surfactant used in the detergent is:
substantially the same as the amount of sodium di-salt or less than the amount of sodium soap (especially about 80 m of di-salt)
% by weight, preferably not more than about 60 ffil11%.

The amount of detersive active co-surfactant preferably does not exceed 50ffif1% of the sodium di-salt, smaller amounts, for example not exceeding 35% by weight, especially not exceeding 20% by weight, are particularly suitable. obtain. Such cosurfactants are selected, on the one hand, in order to achieve the desired washing results (i.e. in particular to further improve the primary washing results). However, in an important aspect of the invention, particularly considering the overall composition of the detergent mixture of the invention, there is still another parameter of particular importance, namely the ecological compatibility of such co-surfactants. It is about being sexual. It is preferred to use co-surfactants with minimal toxicity (eg, as measured against aquatic toxicity models as described above). By choosing an environmentally compatible cosurfactant, on the one hand, and by lowering its usage in detergent concentrates, on the other hand, an optimization is achieved with respect to the problem that the present invention seeks to solve. (i.e. high environmental compatibility can be achieved as well from a surfactant point of view).

Suitable cosurfactants are, for example, fatty alcohol sulfates and/or alkyl glucosides and detergency enhancers (eg fatty acid alkanolamides).

In the present invention, fatty acid soaps, especially natural and/or
or synthetic C, -C0, preferably C11-C11
, more preferably C, -C, fatty acid sodium soaps are of interest as co-surfactants for the sodium di-salts.

In one important embodiment, both the sodium di-salt and the soap used as co-surfactant are derived from the same natural and/or synthetic fatty acid or fatty acid mixture. In this case, it is clear that the preparation of such surfactant mixtures can be carried out particularly simply by controlling the partial sulfonation of the carboxylic acid or carboxylic acid derivative starting material.

In one important aspect of the present invention, ABS or LAS detergent surfactants, which are currently widely used, are not used.

In the detergent concentrates according to the invention, an increase in detergency can be achieved by the coexistence of further standard builder components (in particular sodium-alkaline builder components, such as water glass and/or soda). Water glass, i.e. soluble sodium silicate, e.g.
Amounts up to ffiflt% may be used. A suitable amount of soda is, for example, 5 to 35% by weight. However, E.D.
It is also possible to use calcium complexing agents known in the detergent industry, such as TA, NTA and/or polycarboxylates. Other standard additives in detergent mixtures are polymer components, for example based on carboxymethylcellulose, to improve the soil suspending power, as well as enzymes, fragrances, pigments and other auxiliaries customarily used in detergents. . All of these additives are typically present in small amounts, especially in amounts not exceeding about 35%, preferably not exceeding about 10-20% by weight of the detergent concentrate. All these amounts are weight percent based on the detergent concentrate.

The use of bleaching ingredients (in particular percarboxylic acids or peroxide compounds) and activators suitable therefor (eg tetraacetylethylenediamine or tetraacetylglycoluril) is also encompassed by the invention. However, in a preferred embodiment, the sodium perborate salt commonly used in detergents is used. The detergents or detergent concentrates of the invention contain sodium perborate in an amount not exceeding 15fflff1%, and especially preferably do not contain sodium perborate.

A preferred amount of soluble sodium silicate as an additional reinforcement builder component in the detergent concentrate is, for example, about 5 to 10% by weight. If soda and/or carbohydrates are required, for example about 5-25 ffl! It may be used in an amount of %.

In one important aspect, the components described in the applicant's earlier West German patent application P3604039.8 may also be used. In this embodiment, preference is given to adding swellable micronized layered silicates selected from 11V, which consist of natural or synthetic crystalline smectites having a highly swellable scrap structure. Particularly suitable sheet silicates are smectites, for example mica-like sheet silicates with a three-layer structure selected from the group comprising montmorillonite, hectorite, saponite, beidellite.

Bentonite is a suitable natural material known to contain layered silicates with a predominantly montmorillonite structure. Corresponding smectite clays are commercially available under various trade names.

[LaponiLe RDJ, [Dis-This-Extra]
) J, “Thixogcl J, [Softclark J, etc.] may be mentioned by way of example.

The amount of softening swellable island silicates present in the detergent concentrates of the present invention is from about 3 to 25% by weight, preferably from about 3 to 15%, more preferably from about 5 to 10% by weight. It is. It has been found that such additives can also provide a builder effect with respect to primary detergency to some extent.

However, in this aspect of the invention, inter alia, the advantages of softening in the washing liquor can be exploited as described in detail in the above-mentioned West German patent application P3604039.8.

The detergent concentrates of the invention may be prepared in either liquid or solid form. Solid multi-component detergent mixtures are generally preferred. Particularly preferred are powdered and/or granular formulations.

EXAMPLES Example 1 The following comparative laundering tests were carried out on a standard test textile product (II-DS-PRC) consisting of dust/fat soiled polyester/refined cotton. The test was carried out under the following washing conditions: Round-o-meter washing at 260°C; washing and rinsing with Benraad water with a hardness of 6°Gh; bath ratio: 1:30: 10 steel balls; 30 minutes. Washing: Rinse 4x30 seconds.

The surfactant-containing detergent used in the first test was α-
It was a sodium salt of sulfo C1@C1@tallow fatty acid. This surfactant was used in the absence of other ingredients at a dose of 0 to 3.0 g of active substance di-salt/i2 washing liquor.

The second test used the same detersively active surfactant with a Na*SO- of 2.0 in each test. The test was carried out under the same conditions as described above.

The rinsed and dried test textiles were treated with EIrefomaL;
Table 1 shows the standard reflectance values measured using the Rl Zeiss Co., Ltd.).

Table 1 (Regular reflectance values) Table 2 shows the results of a similar test using soft water (0''Gh).

Table 2 (Conventional Reflectance Values) From the results in Tables 1 and 2, it can be seen that the problems that the present invention sought to solve were solved as follows: α-sulfo c , -c Washing liquids containing ts fat fatty acid sodium base as a detersive active surfactant have little or no bleaching effect on soiled standard test textile products up to ASff1l-1.5g/i2 in the washing liquid. Not shown. When the surfactant ΔS content in the washing liquid increases, the desired washing effect can suddenly be obtained.

Such a sudden improvement in detergency occurs in principle in the same way, but more markedly, when sodium sulfate is added. In that case, such a phenomenon that depends on the ΔS content m in the washing liquid will occur at a lower HeS concentration, and the detergency will also be further enhanced.

This is influenced to some extent by the hardness of the water in the wash liquor. When using soft water, a sudden increase in activity when adding sodium sulfate builder occurs at a sodium content of only about 1 g/+2 salt A S fill in the wash liquor. When using water with medium hardness (16°Qh),
Surfactant ASf also in the presence of sodium sulfate builder
It is necessary that l be at least about 1.5 g/e. Washing results at two salt concentrations of the present invention (conventional reflectance values)
However, it is interesting that the results are clearly better when using hard water (16°Gh) than when using soft water.

In any test series, once the di-salt concentration in the wash liquor reaches or exceeds a threshold, the primary cleaning power increases from an initial very low level to a relatively high level comparable to commercially available detergents. The level suddenly rose.

In another wash test carried out under the above conditions, soiled test textiles 1 (-DS-P RC) were washed with medium hardness (
α-Sulfo-CI@-Cts fatty acid sodium base salt 2 Op/(l) is contained as a sole surfactant in water of 16° Gh), and sodium sulfate 8.0 g/l is further contained as a detergent-enhancing pill. The standard reflectance value measured for the washed and dried test textile was 73.9. This value was compared to that measured using a commercial detergent in a round-o-meter under similar conditions. The results obtained are sufficiently comparable.

Example 2 To test the relationship between di-salt and sodium sulfate content and detergency, a wash test was carried out under the following conditions: Round-o-meter wash R1: 60°C; water hardness = 16
°Gh Bath ratio: 1:30; 10 steel balls; wash for 30 minutes; rinse 4X30 seconds.

I-f-D S-P as a dirty standard test textile product
RC was used.

In both tests, the detergent dosage was 7.5 g/a. On the other hand, the di-salt content is 1Qffiff1%, 201
[If1%, 301f1flt% OJhi 40fft11
The detergents were prepared in such a way that the amount of sodium sulfate was increased in steps from 0 to 60% on the other hand. The remaining water was added as needed.

The washing results obtained are shown in Table 3. The water control value under similar wash conditions was 25.9 (% Conventional Reflectance).

The data presented in Table 3 show that, on the one hand, increasing the disalt content in the washing liquor and, on the other hand, at a constant disalt content, the sodium sulfate builder in the washing liquor in relation to the desired enhancement of the primary detergency. This is the value when ■ is increased. Under the selected test conditions, increasing the di-salt content by 0.75 glQ resulted in a greater degree of detergency enhancement than a similar increase in the amount of sodium sulfate. The results in Table 3 show that a sudden increase in primary detergency occurs at a concentration of about 1.5 g di-salt/i2 washing liquid, and that standard reflectance values at the level obtained by standard detergent formulations are achieved. It is also reflected in

Other factors that must be taken into account in this regard are, inter alia, that the detergent mixtures used in this test series do not contain additional detergency-enhancing ingredients.
