Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to tableware, such as plates, bowls,
Regarding a light liquid detergent composition having utility unique to hand-washing of pots, glass dishes, silver dishes, and the like, more specifically,
The present invention relates to a liquid dish detergent composition which is stable, has a long-lasting foaming property, has a good rinsability, is soft to the skin, and is effective for removing oil stains from dishes.

[0002]

2. Description of the Related Art Good foaming properties of detergent compositions are considered by consumers as having good detergency. However, long-lasting bubbles are also considered awkward, and moderate or rather low foaming does not appear to be an adequate measure of cleanliness per se. So, despite many efforts made to optimize foamability, detergency was not necessarily improved.

Oil stains are generally considered to be the most difficult to remove by hand washing. Effective removal of greasy soil often requires hot water to help dissolve and remove the oil.

Therefore, it is possible to remove oil stains and other stains from dishes by using water warmed to room temperature or high temperature, and it is effective for removing the stains. Devising a detergent composition is in a very advantageous environment.

Among the anionic surfactants, those whose main component is magnesium as a counter ion, that is, a cation, are known to improve the oil drainage performance. However, improving the oil drainage performance generally increases the irritation to the skin, for example, the hand.

It is also generally known that the use of milder surfactants will somewhat improve the rough hand feel of magnesium-based anionic surfactants. Alkyl polygluside (APG) nonionic surfactants have been proposed for this purpose. However, although the alkyl polygluside surfactants have foaming properties, they generally do not have as good foaming performance as other conventional foaming surfactants.

Another feature required for hand-washing dishwashing detergents is the ability to easily wash away a large amount of foam in order to obtain good washing performance. APG
In the compounded surfactant system, the bubbles generated are not always satisfactory in rinseability.

[0008]

Therefore, the problem to be solved by the present invention is to provide a dishwashing water-based composition which is sufficiently soft to the skin, that is, mild, has good foaming properties, and has good oil cleaning performance. It is to be.

Another problem to be solved by the present invention is to provide a dishwashing water-based detergent composition having a good bubble rinsing property.

The present invention is to provide a composition which solves the above problems of the conventional liquid dishwashing detergent composition and achieves the above-mentioned problems. While such compositions may be prepared from other known ingredients, unique combinations and combination ratios can provide novel and beneficial results.

Including

In this specification, all percentages and percentages are by weight unless otherwise indicated.

The components of the composition of the present invention will be described in more detail below.

The present invention provides, in part, a combination of a foam stabilizing and foam enhancing evolution of an alkyl polyglucoside (APG) and an alkanolamide at a constant concentration of surfactant and foam stabilizing component. It is based on the completely unexpected discovery that it has a significant impact on oil removal performance. More specifically, the foam-stabilized alkanolamides alone have some enhanced oil removal performance when compared to the best commercially available products. It was also clarified that the oil removal performance was further significantly improved in the system containing both. In addition, alkyl ether sulfates with less than 3 moles of ethylene oxide
(AEOS), e.g., AEOS-1EO or AEOS-2EO, is used to maintain sufficient softness (mildness) to the skin, while AEOS-3EO, a similar composition containing 3 moles of ethylene oxide. More bubbles can be produced compared to. In addition, the use of a low-concentration bubble-enhanced alkanolamide component (B), in combination with the specific surfactant system (A), achieves good rinsing properties of tableware without impairing cleaning performance. .. For example, a light hand wash product currently available to the assignee as a commercial product.
(Product name Liquid Palmolive, 17% NaLAS, 13% AEOS-3
EO, 4% LMMEA, 3.3% SCS + SXS, 0.5% inorganic salt, balance, fragrance, colorant, ethanol, water), the same formulation without LMMEA removes only 5 mg of oil stains (lards). Approximately 25 mg of oil stain (lard) was able to be removed as compared with the case where it was not. However, in compositions of the present invention containing APG, greasy soil removal is increased to about 80 mg over the LMMEA concentration range of about 1-4% by weight of the composition. These measured values were based on a surfactant system where the counterion of the anionic surfactant was sodium. In systems using magnesium salts of anionic ABS surfactants, both the concentration of its Mg ions and its alkanolamides have a strong effect on oil stain removal. For example, 10% by weight linear dodecylbenzene sulfonate (LAS) / 12% by weight fatty acid C ₁₂ -C ₁₆ alcohol ethoxylates (1 mole ethylene oxide (1EO))
/ 6 wt% APG (C ₁₂ -C ₁₆ alkyl; DP = 1.6) when tested in the Baumgartner oil stain removal test,
The oil removal performance obtained at each Mg and LMMEA concentration was as shown in Table 1 below.

[0016]

[Table 1] Table 1 Mg ion% LMMEA% oil removal, mg 0.1 4 37 0.1 2 8 0.4 2 61 0.25 3 60 0.4 4 80 Hereinafter, each component of the composition of the present invention will be described in detail.

(A) Surfactant system (1) The first essential surfactant component is an anionic salt of alkylbenzene sulfonic acid (ABS), preferably a linear C ₁₀ -C ₁₆ alkylbenzene sulfonate. (LAS).

Further, when the magnesium salt is used, it may be, for example, magnesium oxide-neutralized linear dodecylbenzene sulfonic acid, or the magnesium salt may be an electrolyte magnesium salt such as magnesium chloride or magnesium sulfate. Or the like may be added to sodium alkylbenzene sulfonate to form the compound. In the latter alternative, excess magnesium salt electrolyte raises the cloud / clearing point of the composition. However, these undesired effects can be compensated for by adding hydrotropes, as described below.

The anionic surfactant (1) is present in an amount of about 7.5 to about 20% by weight based on the total amount of the composition, or the surfactant (A) (1), (2), (3). And (4) about 28 to the total amount
40% by weight should be present. More preferably, the anionic ABS salt surfactant is about 8 to 1 relative to the total composition.
2 or 15% by weight, particularly preferably about 9 to 11% by weight, for example about 10% by weight, or a surfactant.
(A) (1), (2), (3) and, based on the total amount of (4), preferably about 29-35 wt%, particularly preferably about 30-33
% By weight.

When the concentration of the anionic surfactant is less than 7.5% by weight based on the total amount of the composition, the oil removal at low temperature is not sufficiently improved, and when it exceeds 20% by weight based on the total amount of the composition, Magnesium salt-containing compositions tend to be slightly irritating to the hands.

The anionic ABS in the surfactant system is
It may be in the form of an alkali metal salt or an alkaline earth metal salt, or a mixture thereof. The alkali metal is
Preferred is sodium and potassium, and more preferred is sodium. Alkaline earth metal is

The straight chain alkyl group preferably has 10 to 13 carbon atoms, particularly preferably about 11 carbon atoms on average, for example, by way of example, sodium dodecyl benzene sulfonate straight chain. Salts and / or magnesium salts may be mentioned.

The sodium salt of the anionic surfactant is
It is generally considered to be a milder detergent than the corresponding magnesium salt, but it is less effective at removing oil stains and less foaming. Especially in the presence of dirt. However, when used in combination with APG, AEOS-1 to 2 EO and alkanolamide bubble stabilizing system, sufficient foaming property, oil removing property and mildness can be simultaneously exhibited. On the other hand, the use of magnesium salts of anionic surfactants enhances oil removal performance.
However, the concentration of Mg ions can be made as low as possible depending on the oil removal performance, so that it is possible to achieve the mildness acceptable to consumers. This is particularly relevant in terms of the perceived mild effect reported by small consumer panel of consumers. The same is true for the compositions containing the sulfosuccinate or sulfosuccinamate salt anionic surfactant described below.

[0023] (2) According to one embodiment of the present invention may contain a monoalkyl C ₈ -C ₁₈ sulfosuccinates or sulfosuccinimidyl na mate anions surfactant in the compositions of the present invention .. In particular, the magnesium salt of ABS is a component
(1) is used as all or part of, formulating monoalkyl C ₈ -C ₁₈ sulfosuccinates or sulfosuccinimidyl na mate anions surfactant.

It is disclosed that the foaming power and the detergency are enhanced when blended at 80% by weight. The patents suggest that such compositions are free of petroleum-based anionic surfactants such as alkylbenzene sulfonates and alkane sulfonates. However, other anionic surfactants such as alkyl ether sulphates, alkyl sulphates replace some of the APG or dialkyl sulfosuccinic acid. Di (C ₇ -C ₉ ) alkylsulfosuccinic acid is not considered a mild surfactant and is rough and irritating to the skin.

A small amount, for example up to about 5%, of the dialkyl succinate may be present together with the monoalkyl sulfosuccinate or monoalkyl sulfocinnamate salt. However, monoalkyl esters that are substantially free of dialkyl esters are preferred, with monolauryl esters being especially preferred. The monolauryl ester may be ethoxylated with 4 moles or less of ethylene oxide,

Alkyl mono and polysaccharides are
Due to its foaming property and viscosity improving property, it has recently received much attention as a valuable detergent. Examples of patent literature relating to light liquid compositions containing alkyl monosaccharides include US Patents 4,732,704 and 4,732,696. Alkyl polysaccharides are described, for example, in US Pat.

And a glucoside hydrophilic group having a glucoside unit. The number of glucoside units in any of the surfactant molecules is a real number (i.e., an integer), but the actual physical sample of the alkyl glucoside surfactant is generally shown in the range of glucoside units and It is given as the average value that characterizes the surfactant product. For alkyl chains of similar length, those with a higher DP value are more soluble, whereas alkyl glucosides with a lower DP value tend to produce more bubbles. When the alkyl group contains less than 12 carbon atoms, it is difficult to obtain satisfactory mildness.

The alkyl group is preferably attached at the 1-position of the sugar molecule, but may be attached at the 1-, 3- or 4-position. This produces glucosyl rather than glucoside. Furthermore, in polyglucosides, an additional glucoside unit is attached at the 2-position of the preceding glucoside. In this case, it may be placed in the 3rd, 4th, and 6th positions. Although not desirable, polyalkylene oxides (eg:

To produce these compounds, the long chain alcohol (R ² OH) is reacted with glucose in the presence of an acid catalyst to form the desired glucoside. Alkyl polyglucoside is a two-step process, that is, a short-chain alcohol.
Reacting (C ₁ -C ₆ ) with glucose or glucoside (x = 2-3) to form a short chain alkyl glucoside (x = 1-3),
It can also be produced by reacting this with a long-chain alcohol (R ² OH) to replace the short-chain alcohol to obtain the desired alkyl glucoside. When using this two-step process, the content of short chain alcohols in the final alkyl glucoside material should be less than 50%, preferably less than 10%, more preferably less than 5%. , Most preferably 0%.

The unreacted alcohol or free alcohol content in the desired alkyl polyglucoside is preferably less than about 2%, more preferably about 2%, based on the total weight of alkyl polyglucoside + unreacted alcohol.

(C) Organic solvent A cosmetically acceptable organic solvent, usually a lower alcohol, such as ethanol, propanol, isopropanol, propylene glycol or a mixture thereof, has a low thickening effect, a clearing point lowering effect and a main aqueous solution. It is added to the composition in order to impart a solubilizing effect to components that are difficult to dissolve in the medium. When a solvent is present, the amount of the solvent is usually up to about 10% by weight of the composition, preferably up to 8% by weight, particularly preferably up to about 6% by weight, for example from 2 to 5%. Weight% Ethanol is preferred as the organic solvent.

(D) Hydrotrope The composition typically contains a hydrotrope substance to help solubilize the various components of the composition, maintain a low clearing point and improve viscosity as much as possible. .. Representative examples of hydrotropes include primarily urea and lower alkylaryl sulfonates such as sodium xylene sulfonate, potassium xylene sulfonate, sodium cumene sulfonate and ammonium xylene sulfonate. It is also possible to use mixtures of two or more hydrotropes. If a hydrotrope is used, it is generally used in an amount of about 8 wt% or less, preferably about 6 wt% or less, such as 1 or 2-6 wt%.

In particular, substances used to enhance the softness of the detergent composition to the human hand, such as water-soluble proteins, are often very useful.

Solvents, including water, tend to make the product a transparent liquid, but in some cases it may be desirable to make the product opaque or to impart gloss to the product. For such purposes, opacifying agents, such as behenic acid, or pearl foils or pearlizing compositions, such as higher fatty acid esters of polyethoxyethanol, coconut oil fatty acid alkanolamides and approximately equal amounts of sodium lauryl ether sulfate. It is better to use a mixture. The higher fatty acids usually have 10 to 18 carbon atoms and the polyethoxy content is 1 to 20, preferably 1 to 10.
It is preferable to have an ethoxy group of The alkanolamide is preferably ethanolamide, but may be mixed with isopropanolamide.

(Examples: acylamidopropyldimethylammonium betaines) often improve overall performance.

The viscosity of the detergent composition is further improved by adding thickeners such as gums and cellulose derivatives. The viscosity and fluidity of the product should be such that it can be poured from a bottle, neither splashes nor too fluid. This is because the liquid detergent is usually used in a very small amount in use. Those having a viscosity of 20 to 1000 cps (Brookfield Viscosity spindle No. 1,12 rpm) are useful, those having a viscosity of 100 to 500 c.ps are preferable, and those having a viscosity of about 200 c.ps are preferable.

More volatile substances, for example added with fragrances, preferably lastly and after cooling the composition to room temperature,
Added. When producing opaque or pearlescent detergents, the pearling mixture is also added at room temperature, almost at the end. As the method for producing the composition of the present invention, the above-mentioned method is preferable, but various known methods can be used depending on each detergent composition.

The PH of the formulation is generally about neutral, eg, about 5-8, preferably about 6.5-7.5.

Hereinafter, representative examples of the present invention will be described, which are provided to facilitate understanding of the present invention.
It does not limit the present invention in any way.

Continue this operation until all 0.03g of dirt is added.

(3) Shell Foam Test A water jacket container stirred with a baffle at a constant speed (300 rpm mixing speed) was filled with the main test solution having a concentration of 0.04% in 250 ml of water (150 ppm hardness, 45 ° C.). Continue stirring until the generated bubbles cover the entire surface of the solution. The mixed soil (olive oil, milk, Chrisco and potato sprouts) is gently infused at a constant rate sufficient to disperse evenly over the surface of the solution. The soil first interacts with the surfactant in the solution, depleting the surfactant. After that, the surfactant begins to be drastically reduced from the bubbles. Measure the amount (g) of soil added until the air bubbles immediately collapse.
The results (end point) are shown in Table 2 in g.

Each of these tests was performed 3 times, and the average thereof is shown as a result.

The results of the above tests are shown in Table 2.

(1) + (A) (2) + (A) (3) + (A) (4) + (B).

Both compositions WJ 'and L have good rinsability as compared to commercial products containing trade name Liquid Palmolive and high concentration of oil-removing magnesium but not containing alkyl polyglucosides. Is.

Formulations A-E above are LMMEA for oil removal.
And is sufficient to identify the major and synergistic effects of APG. It has been found that only LMMEA concentration has a detrimental effect on oil removal performance. Other compounding factors (surfactants) do not adversely affect oil removal. Compositions A and D are 4%
It contained LMMEA but a high concentration of oil was removed. On the other hand, Regular Liquid Palmolive removes 25 to 30 mg of dirt. For reference purposes, another major commercial product containing high levels of magnesium to enhance oil removal performance removes 120 mg of soil. However, this commercial product is
Significantly more irritating than Liquid Palmolive in clinical hand soak test. Formulations L and L'also contain high concentrations of Mg, but have high oil removal performance. However, these formulations are clinically milder than the commercially available Mg concentrated products. Product WJ '' containing 6% APG and 4% LMMEA has oil removal performance comparable to Formulations A and D and has been clinically tested to be as mild as Liquid Palmolive. I understood.

The compositions WJ 'and WJ''both have the same mildness as that of liquid palmo rib, but were evaluated as being milder than the commercial products containing a high concentration of Mg. The typical composition WJ '(NaLAS) is not as effective in the standard Baumgartner test as the liquid palmy molybdenum or high Mg content commercial products, but in terms of sample soaking test it gives a Chrisco monoglyceride oil stain removal. Considered to be excellent in.

Oil removal tests were conducted on similar compositions containing 17% LAS.13 AEOS-3EO, 0% APG and 0% or 4% LMMEA. The 0% LMMEA containing composition removed about 5 mg of soil, while the 4% LMMEA containing composition removed 25 mg of soil. This indicates that the synergistic effect of LMMEA and APG enhances performance on oil.

Example IV To test the effect of the sulfosuccinate / sulfosuccinate namate salt anionic surfactant in composition L of Example I, four different surfactants were added to Composition L. 0%, 1.5
%, 3% sulfosuccinate / sulfosuccinate namate salt concentration and tested in the above-mentioned Baumgartner oil removal test and shake foam test using liquid palm palmov (PO

Conclusions of sulfosuccinate performance comparisons Oil wash results tested with various sulfosuccinic acids at 0%, 1.5% and 3% concentrations of oil performance L formulation (MgLAS) are shown for all four sulfosuccinates. As a result, comparable Baumgar toner performance was obtained at all concentrations. Dioctyl sulfosuccinate appears to show a higher performance peak than other materials at 1.5% concentration.

Shake Foam Performance Generally, increasing the sulfosuccinic acid concentration from 0% to 3% tends to increase bubble volume somewhat at each concentration of soil addition. There is no significant difference in performance unless the difference in bubble volume is 50 ml or more. The minimum bubble volume / maximum bubble volume is 50 at each concentration regardless of the type or concentration of sulfosuccinate.
Within ml. Therefore, any of the four materials can be used based on the minimal effect of bubble volume. The most important factor is whether the mildness of the formulation is acceptable to the consumer.

The dioctyl salt of sulfosuccinic acid appears not to provide as mildness as higher higher chain alkyl esters.
