The pigment is a fine powder that has color and is insoluble in water or other solvents, and can give a characteristic color to the bath additive composition.

Referring to FIG. 2, the base may be comprised of a first base and a second base that are distinct from each other.

The base is a main component of the body of the solid bath additive, and may be formed by combining one or more bases with different characteristics.

Although the first base and the second base have different characteristics, they are implemented as a single bath agent product, so they can exhibit differentiated product properties that bath agents with a single characteristic do not have.

Specifically, the first base may include a first flavor, and the second base may include a second flavor, or the first base may include a first functional additive, and the second base may include a second flavor. May contain functional additives.

For example, if the first base and the second base have different colors, they can achieve differentiation in appearance, and if they have different scents, they can display two distinct scents in a single product.

In addition, by separately introducing two or more functional additives that are highly reactive and cannot be introduced simultaneously into the first base and the second base, characteristics that cannot be possessed by a single base-based bath agent can be realized in one product.

In particular, the first base and the second base may each contain raw materials with conflicting concepts due to their characteristics, and one or more formulations with different advantages may be implemented in one product.

However, although the first base and the second base, which have different compositions, are physically combined or bonded, the differentiated product characteristics may be confused or deteriorated due to long-term physical contact.

For example, even though the first base and the second base have different scents, the scent may be transferred to an adjacent base over time, and the scent may be confused through the pore structure of the base.

Therefore, the pullulan coating layer may be formed in an area where the first base and the second base are in contact (Figure 2).

Referring to FIG. 2, the base may have a spherical shape in which the first base and the second base each overlap in a hemispherical shape, and a pullulan coating layer is formed on the surface where the first base and the second base are in contact. The characteristics of the first base and the second base can be completely separated.

The pullulan physically blocks the first base and the second base and at the same time acts as a binder to firmly bind the first base and the second base.

According to another aspect of the present invention, a solid bath agent comprising a base of a predetermined shape consisting of a first base and a second base that are distinct from each other, wherein the first base and the second base include different contents of a foaming agent. is provided.

Although conventional foaming bath products have foaming characteristics, there is a problem that the movement of bubbles is monotonous or the amount of bubbles generated gradually decreases after injection, reducing the original characteristics of the product by half.

However, the solid bath additive composition of the present invention can achieve more diverse foaming characteristics by varying the foaming agent content in each base.

Referring to Figure 3, the solid bath agent may have a cylindrical shape and may be a combination of a cylindrical first base on the left and a second base on the right.

In the cylindrical solid bath agent, the first base and the second base may each contain different amounts of foaming agent, and the foaming power of the first base and the second base may be different, respectively.

Since the first base and the second base have different foaming forces, the cylindrical solid bath agent may exhibit non-uniform or irregular movement as bubbles are generated, unlike single-base bath agents with uniform foaming ability.

For example, when the foaming power of the first base on the left is low and the foaming power of the second base on the right is high, the solid bath agent moves to the left or rotates clockwise or counterclockwise due to the bubbles generated on the right. Movement may vary immediately after injection.

Referring to Figure 4, the solid bath agent may have a spherical or elliptical shape, and may have a second base introduced therein.

In the solid bath agent, when the foaming agent content of the second base is higher, the amount of bubbles gradually reduced as the first base is dissolved may be recovered by the second base.

Therefore, the solid bath additive composition of the above type can be maintained without reducing the amount of bubbles generated until it is completely dissolved after being added to water.

The present invention will be described in further detail through the following examples, but it is obvious that the present invention is not limited by the following examples.

Example 1-1

Example 1-3

A bathing agent composition was prepared in the same manner as in Example 1-1, except that polyvinyl alcohol (PVA) was added to the aqueous pullulan solution.

Example 1-4

A bathing agent composition was prepared in the same manner as in Example 1-1, except that polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA) were added to the aqueous pullulan solution.

Comparative Example 2-1

A bath salt composition was prepared in the same manner as in Example 2, but the aqueous pullulan solution was sprayed on the surface of the bulk formulation to form a film.

Comparative Example 2-2

A bath additive composition was prepared in the same manner as in Example 2, but instead of spraying the aqueous pullulan solution on the surface of the bulk formulation to form a film, the dried solid bath additive was wrapped and packaged with paper packaging, and a silica desiccant was enclosed.

Experimental Example 1: Storage stability evaluation

The bath additives of Examples and Comparative Examples were stored under constant humidity conditions (28 degrees Celsius, 40% humidity) for 30 days, and their performance was evaluated.

A panel with experience in sensory testing in the beauty field evaluated the intensity of fragrance and foaming performance after adding it to water.

If the performance was the best, 5 points were given, and if the performance was the poorest, 1 point was given.

division strength of scent foaming power Example 1-1 4.5 4.7 Example 2 4.8 4.8 Comparative Example 1-1 3.2 2.8 Comparative Example 1-2 3.1 3.7

Referring to Table 1, compared to the bath agent of the comparative example, the intensity of the scent was maintained stably and the foaming power was evaluated as excellent, whereas the bath agent of the comparative example had a decrease in scent intensity and foaming performance as it was stored for a long time. .

In particular, in the case of Comparative Example 1-2 using paper packaging and silica desiccant, the storage stability was evaluated to be low compared to the Example.

The above results suggest that the bath agent of the example can prevent loss of flavor through the pullulan coating layer and maintain stable foaming performance by minimizing contact with moisture in the air.

Experimental Example 2: Evaluation of flavor separation degree

The bath additives of Examples and Comparative Examples were stored under constant humidity conditions (28 degrees Celsius, 40% humidity) for 30 days, and the degree of scent separation was evaluated.

division foaming power Fragrance separation Example 2 4.8 4.5 Comparative Example 2-1 2.6 2.3 Comparative Example 2-2 3.8 2.4

Referring to Table 2, although each bath agent in the example was stored for a long time, each combined bath agent maintained its original scent, whereas the bath agent in the comparative example did not maintain its original scent stably because the scents were confused with each other.

The above results suggest that the original product characteristics of the bath agent of the example can be maintained independently even when two concepts of bath agent are combined.

Experimental Example 3: Evaluation of pullulan coating layer durability

The bath additives of Examples 1-1 to 1-4 were stored for a long time under constant humidity conditions (28 degrees Celsius, 40% humidity), and their performance was evaluated.

The intensity of the fragrance was evaluated in the same manner as in Experiment 1, except that the intensity of the fragrance was evaluated after 30, 60, and 90 days.

division 30 days have passed 60 days have passed 90 days have passed Example 1-1 4.5 4.1 3.7 Example 1-2 4.5 4.4 4.1 Example 1-3 4.3 4.3 4.2 Example 1-4 4.6 4.5 4.5

Referring to Table 3, Examples 1-2 and 1-3 in which PVP or PVA were added preserved the scent more stably than Example 1-1, especially Example 1- in which PVP and PVA were added simultaneously. 4 had excellent storage stability.

The above results show that the bath agent of the example can prevent loss of scent of the bath agent through the pullulan coating layer, and polyvinylpyrrolidone and polyvinyl alcohol improve the durability of the pullulan coating layer, allowing the bath agent to be stored stably for a longer period of time. suggests.
