Description

Washable cleansing stick cosmetic composition and method for preparing the same

Disclosed herein is a cleansing cosmetic composition that is washable type while being manufactured and used in the form of a stick. Specifically, a cleansing cosmetic composition is disclosed that can be applied easily and can be erased quickly and cleanly by simply rinsing with water because it is in a stick form.

In general, the stick-type washable cleansing product using an anionic surfactant has a composition that imparts a cleansing function by containing a large amount of anionic surfactant and a small amount of oil, and is molded into a stick form after mixing with various solvents. Take the way. It has the feature to be easily washed with water after use, but very poor safety against skin irritation. In addition, there is a vulnerability that is difficult to reuse because the product is blown into water after use.

On the other hand, in an attempt to reduce such skin irritation, anionic surfactants are excluded, and nonionic surfactants and general oils are used as the main bases of cleansing, and wax development is used to develop stick-type washable cleansing products. (KR registration 10-1081144). However, it takes a long time because the stick touches the skin so that sufficient amount can be dissolved to give a cleansing function. When washing with water, the wax remains as it is, so it has to be wiped off with tissues or second wash.

Experimental Example  One

After molding the stick-type washable cleansing cosmetic composition prepared in Example 1 and Comparative Examples 1 to 4 with a stick, 20 expert panel agents were used for 1 month, and the physical properties were evaluated. The results are shown in Table 2 below. Indicated. Cleansing time and cleansing power when using the stick products of Comparative Examples and Examples on the face according to general usage. After washing, the washability against water and the feeling after use were evaluated.

The evaluation score was 5 points for satisfaction, 4 points for satisfaction, 3 points for normal, 2 points for bad, and 1 point for bad. The results are shown in Table 2.

Sensory Test Results for Examples and Comparative Examples Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Cleansing time 4.9 4.4 4.0 3.1 3.0 Cleansing power 4.7 4.2 3.6 3.2 3.3 Washability 4.8 3.8 3.2 3.1 3.2 Feeling after use 4.8 3.9 3.3 3.1 3.2

As shown in Table 2, Example 1 of the present invention takes less cleansing time than other comparative examples, and Example 1 contains 10 wt% of a glutamide-based oil-soluble gelling agent, and the gelled oil is dissolved in wax. It melts faster and clears the makeup film. As the glutamide-based gelling agent is reduced and the wax content is higher, the cleansing time is longer and the cleansing power is lowered.

Example 1 is superior to other comparative examples in washability, because the glutamide-based gelling agent molecule itself contains lipophilic and hydrophilic groups and thus has a function as a surfactant. That is, some of the oil-based components contained in the removal of the makeup film form emulsified particles together with water added in small amounts, and in the process, the glutamide-based oil-soluble gelling agent is also collected in the emulsified particles, resulting in a state of being easily washed in water This gets better. Comparative Example 3 and Comparative Example 4 are made of a stick formulation using only the wax, the wax is a material that is difficult to wash well in water because the molecule itself is very lipophilic.

Example 1 was also found to be excellent after use, it can contain a relatively large amount of hydrophilic components such as moisturizers appeared to significantly reduce the skin irritation, dry feeling felt after using a general cleansing product. In Comparative Examples 3 and 4, since the wax was used as a gelling agent, the hydrophilic component could not be sufficiently contained.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention.

Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.
