Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition, and more particularly, to a liquid cleaning composition having a required consistency and a method for producing the same.

[0002]

2. Description of the Related Art Detergent compositions, when considering the ease of use by consumers and, when containing insoluble solids, considering the dispersion stability of the composition, appropriately increase the viscosity of the system. May be required.

[0003] As a conventional thickening method, a method of obtaining a viscosity by mixing different types of surfactants (for example, an amphoteric surfactant and an anionic surfactant) to form a complex, and using a thickener. There are two points of the method.

[0004] In the former, the surfactant content tends to be high, and depending on the type of the surfactant used as a main component, there are also detergent compositions which are hardly thickened. Examples of such a cleaning composition include disodium lauryl polyoxyethylene sulfosuccinate, monotriethanolamine cocoyl-L-glutamate, and sodium polyoxyethylene lauryl ether acetate. Many of these hardly thickening surfactants and their blends are generally hypoallergenic, and are expected to be used for various applications. Is often difficult to get out.

On the other hand, in the method using a thickener, the effect obtained depends on the performance of the thickener, but a viscous detergent composition having a relatively low concentration can be obtained.

[0006] The important properties required of the thickener used in the detergent composition differ depending on the application, but in general, the addition of the thickener to properties other than viscosity, such as foaming properties, feeling of use, low-temperature stability and detergency, results from addition. It has no adverse effect, has low irritation, can provide an effect with a small amount of addition, is physicochemically stable, and is inexpensive.

Conventionally known thickeners include hydroxymethyl cellulose, hydroxyethyl cellulose,
Carboxymethyl cellulose, cationized cellulose,
Polymer thickeners such as polyvinyl alcohol, sodium polyacrylate, starch, xanthan gum, etc., low HLB polyoxyethylene alkyl ether, coconut oil diethanolamide, polyethylene glycol distearate, polyether type having a plurality of hydrophobic groups And nonionic surfactant-type thickeners. In addition, inorganic salts such as sodium chloride and sodium sulfate also exhibit an excellent thickening effect depending on the type of surfactant mainly used.

However, polymer thickeners generally impair the thickening effect due to the presence of electrolytes, exhibit spinnability, may not be uniformly dissolved depending on the composition, and change in viscosity over time. In many cases, it is expensive.
In addition, low-oxygenated polyoxyethylene alkyl ethers with low HLB will impair the low-temperature stability when added in large amounts, fatty acid diethanolamide will not thicken unless added in large amounts, will become slimy if added in large amounts, and will have problems with nitrosamines. Polyethylene glycol distearate has problems of hydrolysis, inorganic salts have limited viscosity-increasing surfactants, and low-temperature stability is impaired when added in large amounts. In the agent.

On the other hand, a polyether-type thickener having a plurality of hydrophobic groups has few of these problems, and can be expected to be used as a general-purpose thickener, as disclosed in JP-A-1-138297 and JP-B-1-49311. In addition, its usefulness with respect to an aqueous surfactant solution is shown. However, the thickening effect is still insufficient, and the amount of the thickener added tends to increase as compared with the polymer thickener.

[0010] For the above reasons, in order to impart an appropriate viscosity to the detergent composition, the concentration of the surfactant is increased, a surfactant which is easily thickened, or a large amount of the thickener is added. In addition, there are many restrictions on the formulation, and too much emphasis is placed on the viscosity of the detergent composition, and other performances such as foaming properties, usability, low-temperature stability, and detergency may be sacrificed in some cases.

Japanese Patent Application Laid-Open No. 10-259112 discloses a compound represented by the general formula R ^1- (OCH ₂ CH ₂ ) n-OR ^{2 wherein} R ¹ and R ² are an alkyl group having 5 to 24 carbon atoms, and n is 1 to The number 9 is shown. Is described as an oily base in a cosmetic composition, but the aim is to obtain a low-viscosity composition, and the thickening effect is not disclosed.

[0012] Under such a background, there has been an eager demand for the development of a detergent composition containing a thickener which exhibits a good thickening effect even when added in a small amount and is also stable physicochemically.
