Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a thickener containing a specific pentaerythritol derivative and a liquid detergent composition containing the same, and more specifically to a thickener containing a pentaerythritol derivative having a specific structure. The present invention relates to a high-viscosity liquid detergent containing a viscous agent and a surfactant different from it, and having improved foaming property, foaming stability, and low temperature stability.

[0002]

2. Description of the Related Art The viscosity of a cleaning composition is increased in order to improve the practical handling of the cleaning composition or to stably disperse a pearling agent, an abrasive and other water-insoluble substances. It may be necessary to add various thickening agents to achieve this purpose. The conventional main thickening means for a detergent containing a surfactant as a main component is an inorganic salt such as sodium chloride.
Known methods include a method of improving the micelle aggregation of the detergent composition, a method of blending a polymeric thickener, and a method of utilizing electrical interaction that acts between the molecules of the surfactant.

The most widely known thickening means is a method using a fatty acid alkanolamide as a thickening agent. Fatty acid alkanolamides, when especially combined with an anionic surfactant, exert an extremely excellent thickening effect and foaming stabilizing effect, but since they contain a nitrogen atom in the molecular structure, they may vary depending on the compounding conditions. Inevitably, coloring of the detergent composition with time is unavoidable, and it has been desired to develop a thickener containing no nitrogen atom, which is replaced with a fatty acid alkanolamide.

On the other hand, an ether of pentaerythritol and a higher alcohol, or an ester of pentaerythritol and a higher fatty acid is disclosed in JP-A-57-158703 as being used as an agricultural chemical powder, and is also disclosed in that publication. It is described in the specification that the polyhydric alcohol derivative having a neopentane skeleton is a compound known as a rust preventive and the like. In fact, JP-A-62-101
No. 93 and Japanese Unexamined Patent Publication No. 62-10194 disclose a technique relating to a fluid composition for traction drive. In this case, the rust preventive effect of the polyhydric alcohol derivative having the neopentane skeleton is used. It is thought that Japanese Patent Application Laid-Open No. 04-304356 discloses a technique relating to an alloyed hot-dip galvanized steel sheet which is excellent in low-temperature chipping property, press formability and weldability, and also in Japanese Patent Application Laid-Open No. 07-304.
Japanese Patent No. 97584 discloses a technique relating to an anticorrosive lubricant for galvanized steel sheets, but in the invention disclosed in the above publication, a pentaerythritol derivative is used for the purpose of improving the fluidity of the lubricant and preventing rust. However, it is not incorporated for the purpose of improving the cleaning agent.

Japanese Unexamined Patent Publication No. 01-67235 discloses an example in which a higher fatty acid derivative or a higher alcohol derivative of a polyhydric alcohol is blended as an ionic surfactant-based aqueous preparation. Pentaerythritol is exemplified as a polyhydric alcohol that can be used in the "Detailed Description of the Invention" of this publication, but no experimental example is disclosed. In the aqueous preparation described in this publication, 1) irrespective of the length of an acyl group or an alkyl group, the thickening effect does not change even if ethylene oxide is added within the range where the number of carbon atoms does not exceed 2) 6. It is said that. Therefore, when the inventor of the present invention synthesized a substance containing pentaerythritol as a hydrophilic group and evaluated its performance, it was found that in the pentaerythritol derivative, if the acyl chain length and the alkyl chain length were not within the specific ranges, It was experimentally confirmed that no viscous effect is obtained, and that when an alkylene oxide or the like is added for the purpose of increasing the hydrophilicity of the pentaerythritol derivative itself, the thickening effect does not appear at any acyl chain length or alkyl chain length. did. That is, little was known about the rheological properties of the substance group consisting of the pentaerythritol derivative, including the aforementioned publication.

[0006]

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The pentaerythritol derivative of the general formula (1) used in the thickener of the present invention has the following general formula (2):

[Chemical 3] And a C ₁₂ -C ₁₄ straight-chain alkyl represented by the following general formula (3): R ¹ -X (3) [wherein R ¹ is the same as defined above and X represents a halogen atom]. Halide,

To do. Further, to describe the pentaerythritol derivative-containing thickener of the present invention in detail, it is necessary that the pentaerythritol ester derivative and the pentaerythritol ether derivative both have an acyl group that is a lipophilic group and an alkyl group be a specific linear carbon atom chain. , Its carbon atom number is 12-14. If the content of the straight chain acyl chain and / or straight chain alkyl group having 12 to 14 carbon atoms in the thickener is less than 70% by weight, the thickening effect is insufficient and the foaming power improving effect is weak.
