Introduction

The ladies and gentlemen inventor of the present invention has been surprisingly found that at least one fluid composition in comprising hypohalite or hypohalogenous acids bleaching components to comprise a kind of 2, the soluble-salt of 4,6 sym-toluenesulfonic acid salt adds the stability of the compositions comprising this hypohalite or hypohalogenous acids bleaching components。The increase of this stability deriving from the soluble-salt comprising a kind of 2,4,6 sym-toluenesulfonic acid salt unexpectedly exceed well over by other, the Stabilization that provides of the aryl sulfonic acid salt stabilizing agent that previously adopts。

Hypohalite or hypohalogenous acids bleaching components are more more unstable than at higher ph values at lower ph typically。So, typical practice is, for instance, by remarkable amounts of sodium hydroxide or other strong hydroxide base being added in these compositionss, compositions pH is increased to 12 or higher。Although these compositionss advantageously show the stability of the increase due to higher pH, they also show due to the negative characteristic of causticity height pH, thus damaging some household surface, the instrument used in health care facilities and the surface of device, more need not mention in the infringement caused when contacting with the tissue or other biological body of user。If as a result of which it is, can provide, a kind of to stablize hypohalite or hypohalogenous acids bleaching components and the pH of compositions does not bring up to the method for so sizable degree will be highly make us desired。If such reactivity stably can also being in harmonious proportion between hypochlorite and various auxiliary agent will be another advantage, these auxiliary agents are not typically included in the fluid composition containing hypochlorite due to the reactivity of auxiliary agent Yu hypochlorite。

Stable benefit can be provided to hypohalite bleaching composition although various arylsulphonates are likely to be identified as, but not yet someone recognizes by 2 in this type of hypohalite or hypohalogenous acids fluid composition, the Stabilization of the exceptionai that the soluble-salt of 4,6 sym-toluenesulfonic acid salt provides。The stability characteristic (quality) of the soluble-salt of 2,4,6 described sym-toluenesulfonic acid salt is to exceed well over the arylsulphonate of previously research, for instance the Stabilization of sodium xylene sulfonate。In other words, although arylsulphonate is likely to be identified as a class potentially acts as the material of hypohalite stabilizer, the present invention the inventors have found that 2, the soluble-salt of 4,6 sym-toluenesulfonic acid salt unexpectedly and is better than other arylsulphonates of hypohalite and the hypohalogenous acids bleaching components having been used in stable liquid compositions unexpectedly。

A.2,4,6 the soluble-salt of sym-toluenesulfonic acid salt

The soluble-salt of 2,4,6 sym-toluenesulfonic acid salt has chemical formula C₉H₁₁SO₃ ^-M⁺, wherein M⁺It is a kind of soluble metal ion such as sodium。The soluble-salt of 2,4,6 sym-toluenesulfonic acid salt has a structure that

The structure of 2,4,6 sym-toluenesulfonic acid salt is characterised by the symmetrical substitution pattern around aromatic ring。Sulfonate group is added in 1,3,5 trimethylbenzene (being also referred to as sym-trimethylbenzene .) to form 2,4,6 sym-toluenesulfonic acid salt, and the formation of the soluble-salt of 2,4,6 sym-toluenesulfonic acid salt, it is possible to realized by any suitable means。

In one embodiment, 2,4, the soluble-salt of 6 sym-toluenesulfonic acid salt can be a kind of alkali metal salt (such as, sodium, potassium, lithium etc.), a kind of alkali salt (such as, calcium, magnesium etc.), 2, other soluble-salts of 4,6 sym-toluenesulfonic acid salt or its combination。One particularly preferred example includes 2,4,6 sym-toluenesulfonic acid sodium (2,4,6SMS)。Otheralkali metal salt of 2,4,6 sym-toluenesulfonic acid salt is likely to and is suitable for use, such as 2,4,6 sym-toluenesulfonic acid potassium, 2,4,6 sym-toluenesulfonic acid lithiums or its combination。

In one embodiment, said composition can include by weight from about 0.01% to about 20% this 2, the soluble-salt of 4,6 sym-toluenesulfonic acid salt, from by weight about 0.05% to by weight about 10% said composition, by weight from the said composition of about 0.1% to about 8% or from by weight about 0.1% to by weight about 5% said composition。

As will be illustrated in instances below, unexpectedly, add other isomers of sym-toluenesulfonic acid salt, such as 2,3,5SMS or 2,4,5SMS, do not provide close to by specific isomer 2, the phase same level of the bleach retention rate that 4,6SMS show when adding in the fluid composition containing hypochlorite。Applicant speculates, without wishing to be bound by any specific theory, 2,4,6SMS and the specific interaction of surfactant micellar cause the strong increase repelling hypochlorite from micellar surface, thus reducing the reaction rate of this hypochlorite and very wide range of surfactant types, as will be described by example below。

Although aromatic sulphonate (also known as arylsulphonate) (being removed 2 generally and especially in the art, 4, aromatic sulphonate species beyond 6SMS) it is described as providing the Stabilization to hypochlorite solutions, have been found that 2,4,6SMS the specific of aromatic sulphonate being much better than previously disclosure stablize species。Applicant speculates, without wishing to be bound by any specific theory, by by 2,4, it is due to 2,4,6SMS inherent stability and 2 to reacting with hypochlorite itself that 6SMS adds the clean benefit of the stability to hypochlorite in the preparation including hypochlorite to, 4,6SMS with the combination of the interaction of surfactant micellar。This type of interaction can be characterized as from liquid behavior, it is clear that causing the association of 2,4,6SMS and micelle, this association causes the adjustment of the net charge on micelle。

In aqueous solution, from liquid ion, such as 2,4, the 6SMS abilities being characterised by they and the surface association of interface such as air-water interface, solid-water interface or micelle or double-layer of lipoid。Several power, are considered as cause the reason associated from liquid ion with these interfaces including so-called hydrophobic and dispersion force combination。The combination of these power can cause, for instance, the electronegative association from liquid ion Yu electronegative surface。In other words, the Coulomb repulsion between electronegative structure can be overcome by the combination of other power。From liquid ion, as 2,4,6SMS is not surfactant on typical meaning。They do not show the unexpected change of the self aggregation depending on concentration, i.e. they do not show the critical micelle concentration in aqueous solution。

Applicant speculates 2,4, the association of 6SMS and all types of micelle causes the more negative electric charge near micellar surface, this so cause that the kinetics of hypochlorite anion from micelle is repelled, this so cause being remarkably decreased of the hypochlorite reaction rate with the surfactant molecule constituting these micelles。Unexpectedly and unexpectedly, 2,4,6SMS from liquid behavior, in conjunction with it about the inherent stability reacted with hypochlorite, cause a kind of mechanism, can be controlled by this mechanism hypochlorite stability and improve, other systems of comprising surfactant and aromatic sulphonate in itself previously known compared to this area。

Table 1 illustrates and is comprising anion surfactant, the stability of the hypochlorite in the different preparations of sodium lauryl sulfate。" bleach retention rate " is represented as at 49 DEG C after 28 days the percentage ratio of remaining initial hypochlorite concentration。The preparation of all examples 1 comprises the sodium hypochlorite of 1% at first。Therefore, preparation 1, it is comparison preparation, it is shown that after 28 days only 11% the retention rate of initial sodium hypochlorite。

Sodium xylene sulfonate (" SXS ") or p-toluenesulfonic acid sodium salt (" Na-PTSA ") are added in the result display of preparation 1-2 and the 1-3 in table 1, both of which is arylsulphonate, it is provided that comprise the preparation increase relative to the bleach retention rate of comparison preparation (preparation 1-1) of anion surfactant。The preparation have hypochlorite use these particular aromatic sulfonate be well known in the art。But, bleach retention rate remains relatively low (being 36% and about 33% respectively) at 49 DEG C after 28 days。

The result display interpolation 2,3,5SMS of the preparation 1-5 in table 1 can also provide the increase of bleach retention rate (34%), is similar to the increase of preparation 1-2 and the 1-3 provided by arylsulphonate。Unexpectedly, but, interpolation 2,4,6SMS can provide the notable bigger increase of the bleach retention rate compared with other arylsulphonates。Such as, preparation 1-6 unexpectedly illustrates the bleach retention rate of 72%, the about twice of the bleach retention rate for being provided by the arylsulphonate of any other test。Applicant speculates, without being bound by theory, 2,4, the increase of the sum of the anionic charge of 6SMS and the near surface providing surfactant micellar from liquid phase mutual effect of the micelle comprising anion surfactant, cause the increase of hypochlorite anion exclusion from these micelles, and thus decrease the reaction of hypochlorite and the surfactant molecule constituting these micelles。

Example 2

Comprise the bleach retention rate of the preparation of cationic surfactant micelle and additive

Table 2 illustrates the composition for preparation 2-1 to 2-8 and bleach stability data。Preparation 2-1 to 2-6 comprisesCETAC, cetyl (C16) trimethyl ammonia chloride ammonium surfactant。Preparation 2-7 and 2-8 comprises amyl group trimethyl ammonia chloride ammonium surfactant。Preparation 2-1 and 2-7 does not comprise stabilization additives (such as, tester)。Preparation 2-2 comprises 1.88%SXS。Preparation 2-3 comprises 3%Na-PTSA。Preparation 2-4 comprises 2% sodium nitrate。Preparation 2-5 comprises 2%2,3,5, SMS。Preparation 2-6 comprises 2%2,4,6SMS。Preparation 2-8 comprises 0.25%2,4,6SMS。Each preparation comprise 1% available alkyl trimethyl ammonium chloride surfactant, 1% sodium hypochlorite (Sterilization bleach liquor natrii hypochloritis) and 2.5% anhydrous reagent level sodium carbonate buffer。

Table 2

Result in table 2 shows that the bleach retention rate of the preparation comprising any one cationic surfactant is excessively poor, does not have remaining hypochlorite at 49 DEG C after aging 28 days。SXS or Na-PTSA is added to and comprisesThe preparation of CETAC can provide some increases of the bleach retention rate relative to tester, but retention rate is still low-down (being 25% and about 14% respectively)。

The result of the preparation 2-6 in table 2 shows to add 2,4,6SMS to and comprisesThe preparation of CETAC micelle is provided the increase (to more than 50%) of the more significantly hypochlorite retention rate than the hypochlorite retention rate provided by other arylsulphonates。As shown in by preparation 2-5, add 2,3,5SMS and there is no the improvement that hypochlorite retention rate is provided, compared to the hypochlorite retention rate provided by tester。

The result of the preparation 2-8 in table 2 also shows 2,4,6SMS adds the unexpectedly big increase (to 61%) comprising the stability that cationic surfactant (having short alkyl chain) additionally provides hypochlorite in the preparation of the micelle of amyl group trimethyl ammonium chloride to。

Example 3

Comprise the bleach retention rate of the preparation of amphoteric surfactant micelle and additive

Table 3 illustrates the composition for preparation 3-1 to 3-6 and bleach stability data。Preparation 3-1 does not comprise stabilization additives (such as, tester)。Preparation 3-2 comprises 4%SXS。Preparation 3-3 comprises 3%Na-PTSA。Preparation 3-4 comprises 4% sodium nitrate。Preparation 3-5 comprises 1.5%2,3,5SMS。Preparation 3-6 comprises 1.5%2,4,6SMS。Each preparation comprises 1%LO, lauryl dimethyl amine oxide surfactant, 1% sodium hypochlorite (Sterilization bleach liquor natrii hypochloritis) and 2.5% anhydrous reagent level sodium carbonate buffer。

Table 3

Table 3 illustrates the stability of the hypochlorite preparation comprising amphoteric amine oxide surfactant (such as lauryl dimethyl amine oxide)。Amphoteric surfactant can show their net charge change as the function of the pH of aqueous solution。Oxide surfactant is due at relatively low pH, for instance under pH2, the protonation of amine oxide head base can present cationic charge, and they are at relatively high pH simultaneously, for instance, will be uncharged under pH11。The pKa value of oxide surfactant typically about 4.5。Therefore, close to pH4.5, the amine oxide molecule of about 50% will be cationically charged, and 50% will be uncharged。Owing to the preparation in table 3 comprises sodium carbonate buffer and therefore shows the pH close to 11.0, being present in the amphoteric amine oxide surfactant in these preparations can completely with out electricity。

In each example, including example 3, when fixing remaining every other concentration for preparation in be in increase every kind of additive of concentration determine bleach retention。Therefore, the bleach retention of report refers to that wherein additive level can be about best preparation, thus producing the maximum bleach retention rate observed under minimum additive concentration。As easily from table 3 clearly, all of preparation, 0% hypochlorite retention rate outside preparation 3-6 (comprising 2,4,6SMS), after showing 28 days。In order to distinguish the bleach retention rate of the preparation of the given additive comprising varying level, must there be some measurable remaining hypochlorites among these preparations。Therefore, about the bleach retention rate information as the function of time, i.e. dynamic (dynamical) information of relevant bleach loss, is measure the time period before 28 days。When not having the hypochlorite that can detect to retain after 28 days in preparation 3-1 to 3-5, the sample of these preparations is analyzed (passing through titration) at additional middle time point within test period of 28 days。

Specifically, the bleach retention rate of all preparations is measured for 7,14,21 and 28 days aging at 49 DEG C。When the preparation of rather unstable, in shorter ageing time, such as the bleach retention rate observed for 7 or 14 days, as the function of additive level, for determining the additive level of the best。The final result obtained for 28 days reported in table 3 for each in these preparations is for optimum addn level。

Result in table 3 shows that the comparison preparation (preparation 3-1) comprising amphoteric surfactant does not have bleach to remain after aging 28 days at 49 DEG C, and is therefore a kind of highly unstable preparation。Add SXS or Na-PTSA (preparation 3-2 and 3-3), even at the level going out best bleach retention rate in shorter time showing, compare tester and do not improve bleach retention rate at 28 days。The general sign of the amphoteric surfactant such as amine oxide in the preparation (as stable) with hypochlorite, it is believed that and teach in the prior art, so there is no to provide a kind of method, select the additive for preparation by the method wherein it is desirable to be that after the time storing 28 days at 49 DEG C, remarkable amounts of hypochlorite bleaching is retained。

The result of the preparation 3-6 in table 3 it is also shown that unexpectedly, is added to 2,4,6SMS in the preparation comprising amphoteric surfactant and is caused dramatically increasing of bleach retention rate, even if at 49 DEG C after aging 28 days。The 58% hypochlorite retention rate of preparation 3-6 is very beat all, time particularly compared with 0% retention rate with preparation 3-2,3-3 and 3-5 of comprising other arylsulphonates。

Example 4

Comprise the bleach retention rate of the mixed micelle of cation and anion surfactant and the preparation of 2,4,6SMS

Table 4 illustrates the composition for preparation 4-1 to 4-11 and bleach stability data。Each preparation comprise be in different ratios cation (And the mixture of anion (i.e. sodium lauryl sulfate, " SLS ") surfactant CETAC)。Each preparation comprise 4%2,4,6SMS, 1% total surfactant, 1% sodium hypochlorite (Sterilization bleach liquor natrii hypochloritis) and 2.5% anhydrous reagent level sodium carbonate buffer。

Table 4

In above preparation, clearly confirmed that by the increase of interpolation 2,4,6SMS bleach retention rate in comprising the preparation of anion and cationic surfactant, crossed over anion and the cationic surfactant concentration ratio of wide scope。The composition of mixed micelle by change in preparation SLS andThe relative quantity of CETAC changes, and total surfactant concentration is fixed on by weight 1%。Additionally, initial sodium hypochlorite concentration (1%) is identical with example 1 and 2 with sodium carbonate buffer concentration (2.5%)。Anion surfactant is and the same SLS used in example 1, andCETAC is and the same used in example 2。

Result in table 4 demonstrates the 2 of appropriate amount, 4,6SMS add to the mixed micelle comprising anion surfactant and cationic surfactant creates anion surfactant and the cationic surfactant ratio crossing over wide scope 50% or bigger aging after bleach reservation level。In other words, in the gamut of the composition of the mixed micelle of test, i.e. from the system (preparation 4-1) rich in anion surfactant to the system (preparation 4-11) rich in cationic surfactant。Preparation 4-1 has anion and the cationic surfactant ratio of 1:19, and preparation 4-11 has anion and the cationic surfactant ratio of 19:1。

Because the relative quantity with the every kind of surfactant existed is changed by the net charge on the mixed micelle of anion and cationic surfactant, result in table 4 also shows 2,4, between 6SMS and these mixed micelles is useful (net charge or compositions independent of these mixed micelles) from liquid phase mutual effect on increase bleach retention rate, consistent with example 1 and 2, wherein add 2,4, the 6SMS bleach retention rates adding the micelle only with anion or cationic charge。This further demonstrate that 2,4,6SMS with the interaction of micelle on source from liquid, and not directly related with the electrostatic charge being present on micelle or be controlled by。

Add 2,4,6SMS and can also change the phase behavior of this type of mixed micelle system。Such as, in each preparation of example 4,2,4,6SMS are included to guarantee that all of mixture is solvable at 49 DEG C with by weight 4%。Under the 2,4,6SMS of lower concentration, some systems are likely to precipitation。

Example 5

Table 5 illustrates the composition for preparation 5-1 to 5-10 and bleach stability data。Each preparation comprises the mixture of cation (amyl group trimethyl ammonium chloride) and anion (SLS) surfactant being in different ratio。Each preparation comprise 0.25%2,4,6SMS, 1% total surfactant, 1% sodium hypochlorite (Sterilization bleach liquor natrii hypochloritis) and 2.5% anhydrous reagent level sodium carbonate buffer。

Table 5

Result in table 5 illustrates the 2 of appropriate amount, 4,6SMS adds in the gamut of the composition creating these mixed micelles in test in the mixed micelle comprising anion surfactant such as SLS and cationic surfactant such as amyl group trimethyl ammonium chloride, namely, from the system (preparation 5-1) rich in cationic surfactant to the system (preparation 5-10) rich in anion surfactant, 49 DEG C after aging 28 days again 50% or better bleach retain level。Preparation 5-1 has anion and the cationic surfactant ratio of 1:10, and preparation 5-10 has anion and the cationic surfactant ratio of 10:1。

Example 5 clearly confirms that the increase of bleach retention rate, even if when this cationic surfactant is quite more hydrophilic, for instance, with example 416 carbon of CETAC are compared, and it has the short methylene last-of-chain of 5 carbon。These results show 2,4,6SMS and the association of the anionic-cationic micelle mixed not strongly affecting by the character of the methylene last-of-chain of this surfactant。Again follow determine increase needed for bleach retention rate 2,4,6SMS the method for optimised quantity, wherein to a series of additive concentrations at 49 DEG C aging after test, and then select to meet needed for desired bleach retention rate 2,4,6SMS floor level。0.25%2,4,6, SMS be enough to realize to store 28 days at 49 DEG C after 50% or more hypochlorite reservation level。

Example 6

Comprise the bleach retention rate of the mixed micelle of both sexes and anion surfactant and the preparation of 2,4,6SMS

Table 6 illustrates the composition for preparation 6-1 to 6-10 and bleach stability data。Each preparation comprise be in different ratios both sexes (And the mixture of anion (SLS) surfactant LO)。Each preparation comprise 1.5%2,4,6SMS, 1% total surfactant, 1% sodium hypochlorite (Sterilization bleach liquor natrii hypochloritis) and 2.5% anhydrous reagent level sodium carbonate buffer。

Table 6

Result in table 6 shows to add 2,4,6SMS to the increase of the bleach retention rate after weathering of the gamut that the mixed micelle crossing over test can be provided to form in the preparation of mixed micelle and the hypochlorite comprising anion and amphoteric surfactant。The ratio ranges of anion and amphoteric surfactant is from 1:10 to 10:1。As in the example of other descriptions, along with the level increasing by 2,4,6SMS, as the function of the ageing time at 49 DEG C, monitoring cross over different mixed micelle composition (from rich in the moon to rich in both sexes) the bleach retention rate of preparation。These study confirmation, for the constant total surfactant level of the 1% of selection, and for 1% hypochlorite concentration selected, add 1.5%2,4,6SMS provide being across the full breadth of mixed micelle composition at 49 DEG C after aging 28 days 50% or better approximate minimum needed for the increasing of bleach retention rate for this specific mixed micelle preparation。As pointed out in other instances, the bleach retention rate of the surfactant that the identical total surfactant concentration 1%, identical concentration of sodium carbonate (2.5%) are independent with under identical hypochlorite concentration's (1%) is non-existent 2, under 4,6SMS or be worse far away under the existence of some other arylsulphonates such as SXS or Na-PTSA being known in the art。

Example 7

Comprise the bleach retention rate of the mixed micelle of anion and nonionic surfactant and the preparation of 2,4,6SMS

Table 7 illustrates the composition for preparation 7-1 to 7-4 and bleach stability data。Each preparation comprise anion (SLS) and nonionic surfactant (N91-6) mixture。N91-6 is a kind of alkyl ethoxylate surfactant, and wherein methylene chain length is from C9 to C11 and has the ethoxylation of average 6 moles。Each preparation comprise 2%2,4,6SMS, 1% total surfactant, 1% sodium hypochlorite (Sterilization bleach liquor natrii hypochloritis) and 2.5% anhydrous reagent level sodium carbonate buffer。

Table 7

Result in table 7 shows 2,4,6SMS adds the bleach retention rate that can be provided in the preparation of mixed micelle and the hypochlorite comprising anion surfactant and nonionic surfactant (alkyl or alcohol ethoxylate) in the scope that the mixed micelle with different anion surfactants and nonionic surfactant ratio forms to and increases。These mixed micelles (wherein 2 of varying level are monitored via kinetics by aging at 49 DEG C, 4,6SMS is attached in the mixed micelle system crossing over a series of compositions, from rich in anion to rich in nonionic) the bleach retention rate method evaluating bleach retention rate and increase can be also used for showing being likely to it is contemplated that show 50% or the scope that forms of the mixed micelle of better hypochlorite retention rate at 49 DEG C 28 days after。Therefore, under the constant total surfactant concentration of 1%, when keeping the bleach retention rate of at least 50%, the alcohol ethoxylate in conjunction with 0.4% or more (40%, relative to surfactant bag) is possible。This result is (namely, when keeping relatively high bleach retention rate, the alcohol ethoxylate surfactant of relative high levels is includable) it is beat all, since it is known be alcohol ethoxylate surfactant easily and sodium hypochlorite reaction, cause significant bleach to lose。

Even if including more than under the mixed micelle composition of 40% relative alcohol ethoxylate, still observing significant bleach retention rate when 2,4,6SMS are present in this preparation。Therefore, depend on desired hypochlorite concentration or retention rate, by 2,4, the 6SMS compositionss adding the mixed micelle comprising anion surfactant and nonionic surfactant to can be used for produce under somewhat lower hypochlorite concentration or retention, there is the preparation rich in non-ionic mixed micelle。In other words, when relatively low bleach retention rate is acceptable, it is possible to adopt the alcohol ethoxylate of higher concentration。

These results also show 2,4, the increase that can provide beat all bleach retention rate from liquid phase mutual effect between 6SMS and anion and the mixed micelle of nonionic surfactant, even if when this nonionic surfactant known and hypochlorite are relative reactivities。These examples confirm that be not unique by adding the benefit of bleach retention rate realized in the hypochlorite preparation containing different surfaces activating agent to by 2,4,6SMS for single surfactant types jointly, and unexpectedly consolidate。

Example 8

Determine that 2,4,6SMS bleach retention rate in comprising the preparation of sulfonate and ethoxy sulfate surfactant increases benefit

2,4,6SMS comprise hypochlorite, sodium carbonate and ethoxy sulfate (CS-230, sodium salt) or aromatic sulphonate (S-101, sodium salt) surfactant micelle preparation in bleaching increase benefit and study as the function of the level of combine in time 2,4,6SMS。CS-230 is a kind of alkyl ethoxy sulfate (can obtain from Stepan Co.), andS-101 is a kind of alkylbenzenesulfonate (can obtain from Stepan Co.)。

Surfactant level is fixed on by weight 1%, and carbonate is horizontally fixed on by weight 2.5%, and the initial concentration of sodium hypochlorite is by weight 1%。It is prepared for six kinds of preparations of every kind of surfactant types, containing 0%2,4,6SMS as tester, and the 2,4,6SMS of five levels (in the scopes of by weight 1% to 5%)。These preparations are stored in the teat glass of in a water bath 49 DEG C。After 7,14,21 and 28 days, determine sodium hypochlorite concentration by titration。Table 8 summarizes these results, and wherein percentage ratio bleach retention rate refers to the percentage ratio of the original sodium hypochlorite concentration found in this sample that day in measuring samples。

Table 8

These results show when not having interpolation 2,4,6SMS (0%), and the bleach retention rate of preparation is with aging rapid decrease, and these results illustrate the difference of bleach retention rate between both surfactants, whereinS-101 illustrates the morning of better retention rate after 7 days。

Result in table 8 shows to add 1%2,4,6SMS to haveThe preparation of CS-230 makes bleach retention rate increase to 50% from 0% after 28 days aging, and seemingly higher levels of 2,4,6SMS do not increase the bleach retention rate of this preparation。

Result in table 8 also shows that adding 2,4,6SMS comprisesThe increase of the highly significant of the bleach retention rate of the preparation of S-101 surfactant, the size of the benefit wherein adding 2,4,6SMS is clearly shown that behind 21 days or longer time。These data may indicate that the maximum that increased by the bleach retention rate of 2,4,6SMS forS-101 is somewhat smaller, withCS-230 compares。Such as, after 28 daysS-101 preparation demonstrates the retention rate within the scope of 25%-40%, andCS-230 preparation demonstrates the retention rate within the scope of 30%-50%。

Example 9

Increased by the bleach retention rate of 2,4,6SMS in comprising the preparation of water-immiscible solvent and hypochlorite

Remarkable amounts of water-fast component such as perfumery oil or other oil or solvent are attached to and are probably important for adjusting the attractive in appearance of these preparations and/or clean-up performance forming so-called microemulsion in cleaning preparation。This type of component, even if when being dissolved in the preparation comprising hypochlorite, often results in unacceptable hypochlorite loss when aging。In other words, hypochlorite can not only because these oil be dissolved by surfactant and eliminate with the reaction of these oil。

The increase adding the bleach retention rate of 2,4,6SMS realizations provides the preparation with significantly improved hypochlorite retention rate (even if after changing at 49 DEG C), and these preparations can include remarkable amounts of water-fast oil。

As an example, using SLS to dissolve a kind of water-fast oil or solvent, M1214, cross over a series of oil concentration, wherein preparation also comprises sodium hypochlorite。M1214 is a kind of C12-C14 diformamide and obtains from Stepan Co.。

From practical point of view, it is desirable to liquid formulations is crossed over series of temperature and kept single-phase, i.e. the muddiness of preparation should do not isolated or cause to oil, when the product of clarification is desired。Closing for given surfactant-line of oils, interpolation is not other water-soluble components of real surfactant, such as SXS, it is possible to increase dissolving or improving the preparation robustness to variations in temperature of oil。

Comprise 1% and the preliminary research of the even preparation of 2%SLS (under the existence of 2.5% sodium carbonate and 1% sodium hypochlorite) and also the M1214 solvent that is included between 0.25% and 1% at room temperature and be not all clarification at 49 DEG C。So, SLS is probably the selection of the relative mistake for being dissolved in this solvent comprised in the electrolytical preparation of solubility by hypochlorite and the rather high concentration of carbonate offer。With by weight 1.5% to 2,4,6SMS is added the improvement providing the oily dissolubility crossing over oil level scope interested in identical preparation。Adding 2,4,6SMS with 3% and demonstrate even bigger improvement, it is provided that following preparation, it is clarification that these preparations cross over whole oil concentration scope interested under both room temperature and 49 DEG C。

Therefore, add 2,4,6SMS to provide and making us desired low surfactant/oil ratio rate, for instance, 1% surfactant is than the significantly improving of oil soluble solution under 1%M1214, and it is clarification room temperature and 49 DEG C under the two。Therefore, surfactant concentration increase to 2% is dispensable with the sane dissolving guaranteeing oil, when 2,4,6SMS are included。Ladies and gentlemen applicant speculates, without being bound by theory, the 2 of the increase of generation bleach retention rate, 4,6SMS with surfactant micellar notable from liquid phase mutual effect for regulating surfactant-oil mutual effect in micelle or microemulsion aggregation, the amount that reduces the surfactant needed for dissolved oil be also useful。

It is investigated the bleach retention rate of these preparations aging at 49 DEG C and result is reported in table 9。

Table 9

Result in table 9 illustrates to add to 2,4,6SMS to comprise and creates dramatically increasing of at 49 DEG C aging 28 days after bleaching agent retention rates in the preparation being in the sodium hypochlorite of variable concentrations, sodium carbonate and SLS。Preparation 9-5 to 9-8 shown in table 9 also illustrates that and adds dramatically increasing of 2,4, the 6SMS bleach retention rates providing the preparation comprising insoluble oil such as M1214 with 3%, even crosses over the oil concentration of wide scope。Ladies and gentlemen applicant speculates, without being bound by theory, 2,4,6SMS with surfactant aggregates from liquid phase mutual effect by reducing or eliminating the increase close to hypochlorite and the bleach retention rate reacting this type of system of offer with hypochlorite of the component that is maintained in these aggregations。This benefit advantageously occurs, no matter with remarkable amounts of water-fast oil (wherein oil is present in this system), or need not (wherein oil is not present in this system) these surfactant aggregates swelling。So, the component in aggregation can be protected from the reaction with hypochlorite。In other words, any additional component of surfactant molecule and aggregation, for instance both the water-fast oil of dissolving, spice etc. can be protected in this aggregation。

So, the bleach retention rate provided by 2,4,6SMS increases mechanism and does not rely on the special properties of surfactant or the oil constituting these aggregations, although the structure of these surfactants and oil may determine that the inherent reactivity of they and hypochlorite。Use 2,4,6SMS therefore can allow to comprise spice, oil in a kind of metastable liquid or be other components of relative reactivity with hypochlorite, by protecting this type of reactive component to avoid the interaction with hypochlorite。

Example 10

Increase from the bleach retention rate that 2,4,6SMS is added to the preparation comprising anion surfactant, hypochlorite, sodium carbonate and sodium hydroxide

Through increasing bleach retention rate frequently with interpolation sodium hydroxide (caustic soda)。Along with the level of the caustic soda added in preparation increases, pH will tend to improve, and for skin irritation and some household surface of erosion, the probability such as inside and outside building coating is likely to raising。In the effort of hypochlorite cleaning agent of the pH feature with milder is provided, it is possible to make caustic soda level minimize by adding other buffers such as sodium carbonate。

The impact of the bleach retention rate adding the 2,4,6SMS preparation on comprising 1%SLS, 1% hypochlorite and different amounts of sodium hydroxide and sodium carbonate is shown in Table 10。It is prepared for multiple preparation and makes its at 49 DEG C aging 7,14,21 days and 28 days。After aging, determine remaining hypochlorite level by titration。Only the final data after aging 28 days is shown in Table 10。Because the sodium hydroxide of varying level is added in preparation, the initial pH change of these preparations, higher and relatively low when it is absent from when adding sodium hydroxide。

Table 10

Result in table 10 illustrates, without sodium hydroxide or 2,4,6SMS, bleach retention rate is that relative mistake (bleach retention rate 24%) is even if under the sodium carbonate level of 5%。Under the existence of by weight 1%2,4,6SMS, but without sodium hydroxide, even if bleach retention rate dramatically increases without carbonic ester (bleach retention rate 49%, compared with 0%)。These results show that by 2,4,6SMS being added to the very important benefit provided in this type of preparation。

Result in table 10 also illustrates that when there is 0.2% sodium hydroxide 2,4,6SMS significantly increase bleach retention rate, create to compare and only add 0.2% sodium hydroxide and there is no 2,4,6SMS attainable better bleach retention rates, particularly under the sodium carbonate level lower than 2.5%。

Even if under the sodium hydroxide levels of 0.5% and 0.75%, cross over different carbonate concentration, comprise 2,4,6SMS preparation bleach retention rate up to about 2.5% carbonate level down to less with the system the same good (if being not better than) without SMS。

Result in table 10 illustrates 2,4, even if 6SMS adds to significantly increases bleach retention rate in preparation under the sodium hydroxide added and sodium carbonates' presence, namely, add 2, the benefit of 4,6SMS is not the details depending strongly on the electrolyte of the preparation comprising anion surfactant and sodium hypochlorite, buffer agent and therefore pH。

In addition, (namely these results illustrate bleach retention rate, stability) can increase, when including seldom or there is no the highly basic such as sodium hydroxide of interpolation (such as, wherein this preparation comprise by weight less than about 0.2%, 0.5% or 0.75% soluble hydroxide salt)。Owing to needs seldom or need not increase stability by sodium hydroxide, the pH of gained preparation can substantially milder, if it is desired to words。Such as, pH can be less than about 12, less than approximately 11, less than approximately 10 or from about 10-12。

Example 11

Increase from the bleach retention rate that 2,4,6SMS is added to the preparation comprising amphoteric surfactant, hypochlorite, sodium carbonate and sodium hydroxide

In this example experiment with carry out in the similar fashion described in example 10 above, but use one amphoteric surfactant (LO, dimethyl alkylamine oxide, can obtain from Stepan Co.)。Initial bleach concentration is 1% sodium hypochlorite。At 49 DEG C, the bleach retention results after 28 days is presented in table 11。

Table 11

Data in table 11 illustrate that add the highly significant providing bleach retention rate under the naoh concentration of all tests in preparation to increases 2,4,6SMS, exists and is absent from two kinds of situations of any sodium carbonate。Advantageously, comprise 1%2,4, the bleach retention rate of the preparation of 6SMS (be not necessarily best pitch-based sphere) and 0.2% sodium hydroxide exceedes and is being absent from 2, by adding the bleach retention rate of the system (being in all carbonate levels) that 0.5% sodium hydroxide can realize under 4,6SMS。In other words, when this preparation comprises amphoteric amine oxide surfactant, comparing sodium hydroxide, 2,4,6SMS is one far away better (that is, effective milder simultaneously) bleach retention rate dose。

Example 12

Increase from the bleach retention rate that 2,4,6SMS is added to the preparation comprising cationic surfactant, hypochlorite, sodium carbonate and sodium hydroxide

Experiment in this example to carry out with in the similar fashion described in example 10, but use a kind of cationic surfactant (CETAC, cetyl (C16) trimethyl ammonium chloride, Stepan Co.)。Initial bleach concentration is 1% sodium hypochlorite。At 49 DEG C, the bleach retention results after 28 days presents in table 12。

Table 12

Data in table 12 show that this cationic surfactant had the bleach retention rate being on duty mutually when aging lasting 28 days at 49 DEG C, and interpolation sodium hydroxide and sodium carbonate did not produce the increase of any significant bleach retention rate after aging 28 days individually or together。

Data in table 12 also illustrate that add the highly significant providing bleach retention rate in preparation to increases 1%2,4,6SMS, even if there be no the sodium hydroxide of any interpolation。It is true that under 0% sodium hydroxide added and 2.5% sodium carbonate, add 1%2,4,6SMS (being not necessarily optimum level) and about 50% or more bleach retention rate can be realized。Add the bleach retention that 0.2% sodium hydroxide and 1 weight %2,4,6SMS can improve further in a series of carbonate horizontal extents, thus allow for the motility of preparation so that other aspects such as cost or pH of Optimization product as required。

Therefore the data in example 10,11 and 12 are shown through interpolation 2,4,6SMS increase bleach retention characteristics can use the preparation of sodium hydroxide and/or the sodium carbonate buffer comprising hypochlorite and varying level to realize wherein these compositionss can comprise anion, cation and/or amphoteric surfactant further。Ladies and gentlemen applicant speculates, without being bound by theory, and 2,4,6SMS is not unique with the type from the liquid phase mutual effect surfactant for preparation or electrolyte or buffer components of surfactant micellar。By adding the increase degree of bleach retention rates of 2,4,6SMS realizations, it can be better than by adding caustic soda or what buffer agent realized, it is possible to depends on the character of surfactant in particular formulation。The surfactant demonstrating the bigger reactivity with hypochlorite and bleach retention rate poor under representative condition (namely, it does not have 2,4,6SMS) can tend to from adding in 2,4,6SMS benefited more。
