Detailed Description: 

TECHNICAL FIELD
The present disclosure relates to a shapable solid composition for hair care, which includes a cationic surfactant, anionic surfactant and a viscosity increasing agent.
BACKGROUND ART
The hair of adults may be damaged severely by contamination, frequent permanent, hair drying, hair dyeing and combing. Therefore, a hair cleaning agent having at least a predetermined level of conditioning effect is required. Conventional hair care products for a conditioning effect are provided in the type of a liquid or viscous material and are used by taking such a liquid or viscous material on hands. In other words, such conventional formulations are creamy emulsion formulations, and thus the products cannot be shaped and packed in a desired shape or in an individually wrapped shape.
Meanwhile, a hair care composition for a conditioning effect is required during camping or travelling in addition to the use in daily life. Thus, it is required for a hair care product to have convenient portability.
Therefore, there is a need for studying a solid composition for hair care having shaping convenience and shaping stability so that it may be applied as a commercial product convenient to use during camping or travelling, while not causing degradation of a conditioning effect proper to a hair care product.

As used herein, the term ‘shapable solid’ means a solid formulation which is easily shaped into a specific shape, such as a spherical shape, tetrahedral shape or hexahedral shape, by hands or by using a machine and is not broken under a predetermined level of force (shear) after shaping.
According to an embodiment of the shapable solid composition for hair care, the viscosity increasing agent is a polyacrylate salt.

[Test Example] Test for Solid Formulation Convertibility and Shapability of Composition
Examples 1-15 are determined for solid formulation convertibility and shapability. The ingredients of Comparative Example are base ingredients of the conventional treatment or rinse and cannot be shaped into a spherical shape even though the content of surfactant or higher aliphatic alcohol is increased.
On the contrary, Examples 1-15 are provided as solid formulations as shown in FIG. 1. Particularly, the shape of each of the solid compositions according to Examples 1-14 demonstrates easy shapability and shaping stability as shown in FIG. 2.
The compositions according to Examples 1-4 demonstrates that even when using a different type of cationic surfactant, the compositions can be shaped into a spherical shape.
The compositions according to Examples 5-7 demonstrates that when using at least one type of cationic surfactant, various combinations of cationic surfactants allows shaping into a spherical shape.
The compositions further including a higher aliphatic alcohol according to Examples 8-9 also demonstrates shapability into a spherical shape.
In addition, Examples 10-14 using differently controlled amounts of viscosity increasing agent and anionic surfactant demonstrates shapability into a spherical shape. However, in the case of Example 15, when the composition is shaped into a spherical shape, it shows insufficient stability.
[Test Example 2] Test for Conditioning Effect—Softness and Spreadability of Compositions
To determine the softness and spreadability of the composition according to the present disclosure upon application to hair, Examples 1-14 and Comparative Example are tested as follows.
The spreadability on hands when using each composition and the softness/smoothness of each composition upon application to hair are evaluated by 20 professional panels. After using each of the compositions according to Comparative Example and Examples 1-14, the test is carried out and each composition is evaluated by giving a point of 1 to the lowest result and a point of 5 to the highest result. The results are shown in the following Table 2 as average values.
