DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thickener composition containing a fatty acid alkanolamide type surfactant and a secondary amide type alkanolamide type surfactant, and a liquid detergent composition containing the same. It is.
More specifically, the present invention has an excellent fatty acid alkanolamide content having excellent high viscosity reachability, excellent low-temperature stability, a refreshing feeling when washed out, and excellent foam quality. The present invention relates to a viscous composition and a liquid detergent composition containing the same.

[0002]

2. Description of the Related Art In order to improve the practical handling of a liquid detergent composition, or to stably disperse a pearl agent, an abrasive, or a water-insoluble substance in water, the detergent composition is used. It is known that it is effective to increase the viscosity of a liquid detergent composition, for which purpose various thickeners are incorporated. As a conventional main thickening method, an inorganic salt such as sodium chloride, etc., which expresses a thickening effect by a micelle aggregation effect of a detergent composition, and a compound such as a polymer thickener, There are known those that exhibit a thickening effect, and those that exhibit a thickening effect by utilizing the electrical interaction between surfactant molecules.

As a thickening method utilizing such an electric interaction between surfactant molecules, a method of adding a fatty acid alkanolamide compound to an anionic surfactant is widely used in formulating a detergent composition. . The fatty acid alkanolamide compounds used for such purposes are roughly classified into secondary amide type fatty acid alkanolamides and
Tertiary amide type fatty acid alkanolamides are known, and these are widely used as thickeners for liquid detergent compositions. However, at present, secondary amide-type fatty acid alkanolamides have a higher viscosity-increasing effect than tertiary amide-type fatty acid alkanolamides. Examples of the composition of the agent composition are smaller than those of the tertiary amide type fatty acid alkanolamide. This is mainly due to insufficient low-temperature stability of a detergent composition using a secondary amide type fatty acid alkanolamide compound.
That is, since the secondary amide-type fatty acid alkanolamide compound has a high melting point, there is a problem that the liquid detergent becomes cloudy during low-temperature storage. Therefore, when a secondary amide-type fatty acid alkanolamide compound is blended in an amount sufficient to exert a sufficient thickening effect, particularly on a transparent liquid detergent composition, the low-temperature stability of the obtained composition is deteriorated, and the commercial value is obtained. In many cases.

[0004] Even when a secondary amide type fatty acid alkanolamide compound is mixed with a pearling agent such as ethylene glycol distearate to form an opaque system, precipitation of the secondary amide type fatty acid alkanolamide compound may occur depending on the blending conditions. At the same time, the pearl luster due to the pearl agent may be lost, and in some cases, the pearl agent may be separated. As described above, in a composition containing a secondary amide type fatty acid alkanolamide compound, development of a thickener composition capable of improving low-temperature stability without impairing the thickening effect thereof, and development of a liquid detergent composition containing the same. Was desired.

[0005]
