Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pearlescent detergent composition and a pearlescent concentrate excellent in dispersibility.

[0002]

2. Description of the Related Art In order to improve the appearance of a detergent composition, the production method and the detergent composition are controlled so that a solid oil agent that does not dissolve in the external phase at room temperature is deposited in a specific shape, and a gloss like pearl is obtained. The appearance of is well done in the past. In addition, fatty acid glycol esters are often used as solid fats and oils.

As a method of imparting pearly luster by using a fatty acid glycol ester as a solid fat, (1) a method of incorporating a fatty acid glycol ester into a compounding composition to make the pearl luster appear, and (2) preliminarily giving the pearl luster There is a method in which a concentrated pearlescent solution or paste of a fatty acid glycol ester is prepared under easy-to-obtain conditions and the mixture is mixed at a temperature lower than the melting point of the fatty acid glycol ester to impart pearlescence to the mixed composition.

The composition obtained by the method (1) is often used as a liquid detergent composition as it is, and a function as a liquid detergent is also required at the same time, and the amount of the fatty acid glycol ester is 0.5 to 5. It is usually about 0.0% by weight. Most of the factors that control the appearance of pearlescent luster have characteristics related to the formulation, but once pearlescent luster is present, it has an excellent stability.

On the other hand, N-acyl amino acid type surfactants have been frequently used in detergent compositions in recent years because they are safe and have a unique feeling of use. But,
When an N-acyl amino acid-based surfactant is added to the detergent composition, it becomes difficult to control the precipitation of crystals of the fatty acid glycol ester, which is commonly used as a pearlescent agent. In the case of a detergent composition containing an N-acylamino acid-based surfactant as a main ingredient, the method according to the method (1) described above results in a turbid, opaque detergent regardless of the selection of the conditions. A situation occurs in which the fatty acid glycol ester separates.

Many techniques have been reported for pearlescent compositions that do not contain N-acyl amino acid based surfactants. It is possible to prepare a concentrated pearlescent liquid by these disclosed techniques and impart pearly luster to a detergent composition containing an N-acylamino acid-based surfactant by the method (2). . However, the pearly luster imparted by the above method (2) is generally unstable in many cases, and the pearly luster-containing detergent composition produced, when exposed to a temperature equal to or higher than the melting point of the pearly luster, gives a pearl luster. There were drawbacks such as loss.

Therefore, it has been desired to develop a technique for imparting a stable pearly luster to the detergent formulation containing the N-acylamino acid type surfactant by the method (1).

Many techniques have been reported for pearlescent compositions containing no N-acylamino acid type surfactant. For example, Japanese Examined Patent Publication (Kokoku) No. 47-804 discloses a pearly luster former for clouding a liquid or pasty product, the composition of which contains a fatty acid glycol ester and a fatty acid monoalkylolamide. However, with this composition, the viscosity of the pearly luster-forming agent becomes high, the crystal grain size varies, the crystal form becomes non-uniform, the gloss quality is poor, and the dispersibility is poor. Therefore, it is necessary to dilute with a large amount of water or the like in advance, and there is a drawback that a high-concentration gloss-forming agent cannot be obtained.

Further, Japanese Patent Application Laid-Open No. 58-71021 discloses a method for producing a pearlescent brightening agent. In order to solve the above problems and obtain a brightening agent with a high concentration, a fatty acid glycol ester is used. There is a description of a method in which after heating and melting a fatty acid dialkylolamide, water is added at a temperature below the melting point of the fatty acid glycol ester while cooling. However, in this method, water is not lacquered above the melting point and is in a substantially anhydrous state, and since it is added to water after cooling, the crystal grain size varies, and the crystal form also becomes non-uniform. , The gloss quality will be poor.

Furthermore, Japanese Patent Application Laid-Open No. 57-156409 and Japanese Patent Application Laid-Open No.
Japanese Patent No. 57-156410 discloses a method for producing a high-concentration pearlescent agent dispersion, but since the amount of fatty acid diethanolamide added to the pearling agent increases, the higher the concentration, the more the amount of fatty acid diethanolamide. There are many, and the range of use is limited. Further, in this composition, the crystal grain size varies and the crystal form becomes non-uniform.

In JP-A-8-231985, a fatty acid alkanolamide and an amphoteric surfactant and / or a nonionic surfactant are mixed in a specific ratio to obtain a low-viscosity pearlescent dispersant. Is disclosed.

However, all of these techniques contain fatty acid alkanolamides in their constituent elements. Fatty acid alkanolamide can be an excellent solvent in the pearlization of fatty acid glycol ester, but may cause problems such as coloration due to its production history and changes over time, and it does not contain fatty acid alkanolamide, and therefore is not used in detergent compositions. It has been desired to develop a concentrated pearlescent composition that is easy to mix and does not affect the performance of the detergent composition.

The fourth component in the pearlescent detergent composition of the present invention and the pearlescent concentrate having good dispersibility is
It is water. Although the present invention can be carried out only with water in the case of a usual detergent composition having a pearly luster, it is preferable to use a polyhydric alcohol together in order to increase the fluidity under stirring of the composition.

Particularly when producing a concentrated pearlescent liquid in which the content of the fatty acid glycol ester which is a pearlescent agent is blended to 10% by weight or more of the composition, polyhydric alcohol and water are added to increase the stirring fluidity. It is preferably carried out in a solvent used in combination.

The polyhydric alcohol used in the present invention is preferably one having 2 to 6 carbon atoms and 2 or more hydroxyl groups. Giving a preferred example, glycerin,
1,3-butylene glycol, propylene glycol,
Examples include dipropylene glycol and the like.

When water and polyhydric alcohol are combined, the mixing ratio is 100 parts by weight of water and 12 polyhydric alcohol.
It is preferably 0 parts by weight or less, more preferably 5 parts by weight or less.
It is preferable to mix at a ratio of about 20 parts by weight.

Next, the compounding amounts of the constituents of the present invention will be described in detail.

The N-acyl amino acid type surfactant as the first component according to the present invention is preferably 10 to 30% by weight of the total composition. More preferably 15 to 25% by weight
Is. Content of N-acyl amino acid type surfactant is 1
When it is less than 0%, pearlescent luster is not generated, the dispersion stability of the fatty acid glycol ester is deteriorated, and separation may occur, which is not preferable, and when it exceeds 30% by weight, gelation may occur, which is not preferable. .

The blending amount of the fatty acid glycol ester which is the second component of the present invention is preferably 0.5% by weight to 25% by weight.

When the pearlescent composition according to the present invention is used as it is as a liquid detergent composition, it is 0.5 to 5.0.
More preferably, it is wt%. If the content of the fatty acid glycol ester is less than 0.5% by weight, the pearlescent luster becomes weak, which is not preferable, and if it exceeds 5.0% by weight, the pearlescent luster is not affected, but the foaming power of the liquid detergent composition is not affected. May be significantly reduced, which is not preferable.

When the pearlescent composition according to the present invention is produced as a concentrated pearlescent composition and is used by dispersing the concentrated pearlescent composition in another liquid detergent formulation, the content of fatty acid glycol ester is 5. 0-25% by weight is preferred. If more than 25% by weight of fatty acid glycol ester is blended, problems such as partial gelling or solidification of the pearlescent concentrate occur, which makes it difficult to disperse the concentrated pearlescent composition in other liquid detergent formulations. Is not preferable.

The compounding amount of the water-soluble inorganic salt as the third component of the present invention is preferably 1.5% by weight to 15% by weight. When the water-soluble inorganic salt to be used contains a monovalent cation, it is preferably 3 to 15% by weight, and when it contains a divalent cation, it is more preferably 1.5 to 10% by weight. . When the content of the water-soluble inorganic salt is less than 1.5% by weight, pearlescence does not appear. When the content exceeds 15% by weight, the pearlescent composition according to the present invention is used as it is as a liquid detergent composition. If so, problems such as deterioration of foaming stability will occur, and when used as a pearlescent concentrate, the viscosity of the composition will increase, and the concentrated pearlescent composition will be dispersed in other liquid detergent formulations. This is not preferable because it becomes difficult.

When a concentrated pearlescent composition is blended using the present invention and then diluted with a liquid detergent composition containing other detergent components to produce a pearlescent liquid detergent,
Since the conventional concentrated pearling agent contains a large amount of nonionics such as fatty acid alkanolamides, there is a problem in dispersibility of the concentrated pearlescent composition, but the concentrated pearlescent composition according to the present invention is an essential component thereof. Since the concentrated solution contains no nonions and is adjusted to have a very low viscosity as compared with its solid content, it can be dispersed at room temperature, and the concentrated pearlescent composition according to the present invention can be easily prepared. It has dispersible characteristics.

The detergent composition having pearly luster of the present invention and the pearlescent concentrate having good dispersibility are blended with an amphoteric surfactant and / or a zwitterionic surfactant for the purpose of increasing the solubility of fatty acid glycol esters. You can Particularly preferred amphoteric surfactants and zwitterionic surfactants are surfactants having a structure represented by the following general formula (3).
