Abstract

In the present specification, a washable cleansing stick cosmetic composition comprising an amino acid-based oil gelling agent as a solidifying agent and a manufacturing method thereof are disclosed.

Description

[0002] Washable cleansing stick cosmetic compositions and methods for preparing the same are disclosed.

In this specification, a cleansing cosmetic composition is prepared which is in the form of a stick and is washable in use. Specifically, the present invention provides a cleansing cosmetic composition which can be easily applied because it is in the form of a stick, and can be cleaned quickly and cleanly by washing with water easily.

Generally, stick-type washable cleansing products using anionic surfactants have a structure that imparts a cleansing function by containing a large amount of anionic surfactant and a small amount of oil, . It has the characteristic that it is easy to wash with water after use, but the safety against skin irritation is very insufficient. Also, there is a vulnerability that is difficult to reuse after the product is used in water.

On the other hand, as an attempt to lower such skin irritation, the development of a stick-type washable cleansing product, which is anionic surfactant excluded and which uses a nonionic surfactant and a common oil as main ingredients for cleansing, (KR No. 10-1081144). However, since the sticks touch the skin and the sufficient amount of water is dissolved, it takes a long time to use the cleansing function, and when wiping with water, the wax component is left as it is, and there is a disadvantage of wiping with a tissue or a second washing.

In one aspect, an object of the present invention is to provide a stick-type washable cleansing formulation that does not use wax to solve the disadvantages of wax.

In another aspect, the object of the present invention is to provide a stick-type washable cleansing formulation that minimizes skin irritation.

It is another object of the present invention to provide a stick-type washable cleansing cosmetic composition which can easily wash away components such as a gelling agent as well as a cleansing film and a residual oil in cleansing.

In another aspect, the object of the present invention is to solve the disadvantages of existing products which require a large amount of cleaning for a long time. That is, it is possible to provide a stick-type washable cleansing cosmetic composition which can sufficiently wash even a small amount in a short time.

In one aspect, the washable cleansing stick cosmetic composition according to the present invention comprises an oil phase and a water phase, and the oil phase is a composition comprising an amino acid oil gelling agent as a solidifying agent.

In another aspect, a method for producing a washable cleansing stick cosmetic composition according to the present invention comprises the steps of adding an amino acid-based oil gelling agent to an oil and dissolving the oil at a temperature of 110 to 130 캜.

Experimental Example  One

The stick-type washable cleansing cosmetic compositions prepared in Example 1 and Comparative Examples 1 to 4 were each molded into sticks and then 20 professional panelists were used for one month to evaluate the physical properties. The results are shown in Table 2 Respectively. Cleansing time, cleansing power when using the stick products of the comparative examples and examples according to general usage on the face. After washing, water washability and feeling after use were evaluated.

The evaluation scores were 5 points for satisfaction, 4 points for satisfaction, 3 points for average, 2 points for badness, and 1 point for badness, and 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 After use feeling 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. In Example 1, the oil containing gelled oil in 10% by weight of glutamid-based oil-soluble gelling agent dissolved in wax It melts faster and erases the makeup. The glutamid-based gelling agent is reduced, and the higher the wax content, the longer the cleansing time and the lower the cleansing power.

Example 1 is superior to the other comparative examples in terms of washability because the glutamid-based oil-soluble gelling agent molecule itself contains a lipophilic group and a hydrophilic group and thus has a function as a surfactant. That is, when the cosmetic film is erased, some of the oil components contained in the emulsion particles together with the water to which a small amount of water is added are produced, and in the process, the glutamid-based gelling system is collected in the emulsified particles of the gelling system, Is better. In Comparative Example 3 and Comparative Example 4, a stick formulation was made using only wax. The wax is a substance which does not wash well in water because the molecule itself is very lipophilic.

In Example 1, the feeling of use after use was also excellent, but it was found that it could contain a relatively large amount of a hydrophilic substance such as a moisturizing agent, thereby significantly reducing skin irritation and dry feeling felt after use of a general cleansing product. In Comparative Example 3 and Comparative Example 4, since the wax was used as the gelling agent, the hydrophilic component could not be sufficiently contained.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.

Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.
