Description

Cleansing soap composition for removing makeup

The present invention relates to a cleaning soap composition for removing makeup and oil pollution. More specifically, the present invention provides a cleansing soap composition having an effect of easily removing oil contamination while maintaining the physical properties of soap by combining anionic surfactant as a main cleaning component and nonionic surfactant and encapsulated oil. It is about.

Generally, the amount of sebum to be washed to face washes, such as soap, is about 100 µg / cm 2, while the amount of makeup is individual.

In order to remove the makeup, a cleansing cream is usually used as an essential ingredient, an emulsion. The emulsion serves to easily dissolve contaminants by dissolving the oil component of the makeup and dispersing powder. However, in the case of the oil-based cleansing agent, since it has the same lipophilic component as the makeup component to be cleaned, it has high affinity with the makeup contaminants and excellent cleaning power. There is a hassle.

On the other hand, in order to improve the disadvantages of the oil-based cleansing agent has been developed a surfactant-type aqueous cleaning agent that can be used with water and excellent in use, this has a problem as a cleansing agent because there is a limit to the solubilization and emulsification of the contamination.

Therefore, in an effort to solve the above-mentioned problems, EP 0324575 (Gao) is a makeup containing a branched nonionic surfactant having a hydrophilic-lipophilic balance (HLB) of 3 to 8 with an anionic surfactant. A removal composition is provided, and Unilever patent (application number: 9218792.1) provides a makeup removal composition containing a nonionic surfactant having an HLB value of 10 to 14. However, despite the increase in solubility for oil pollution due to the addition of such nonionic surfactants, it was difficult to obtain satisfactory results, and it was even more impossible to prepare a solid cosmetic soap.

In such a situation, extensive research has been conducted to solve these problems and to prepare a cleansing soap composition having the desired properties. As a result, the present inventors have found that the addition of a nonionic surfactant and microencapsulated liquid oil The present invention has been completed by discovering that it is possible to prepare a solid cleansing soap that is not only excellent in removing makeup but also excellent in use. Hereinafter, the configuration of the present invention will be described in detail.

The present invention relates to a cleansing soap composition comprising a nonionic surfactant and an encapsulated oil in combination with an anionic surfactant as a main cleaning component.

Anionic surfactants used as cleaning components in the present invention include sodium and potassium salts of fatty acids, sodium salts of N-acylglutamate, N-acyl isethionate, sulfosuccinates, alkyl ether sulfates, and alkyl ether carboxyls. Mention may be made of one or more selected from late, acylmethyltaurate.

In addition, as nonionic surfactant, the addition mole number of fatty acid monoglycerides, the monoester of polyhydric alcohol, sorbitan ester (span type), polyoxyethylene sorbitan ester (twin type), and ethylene oxide is 4 thru | or One or more selected from esters of 12 straight or branched fatty alcohols may be used, and the HLB values of such non-ionic surfactants that can be used are about 3 to 14.

In the composition according to the present invention, the nonionic surfactant is preferably used in an amount of 1 to 10% by weight, but when the nonionic surfactant is used in an amount of less than 1% by weight, it does not exhibit sufficient solubility and is used in an amount of 10% by weight or more. This is because the workability is poor, it is difficult to expect a sufficient foaming force, and there is a disadvantage that the feeling of use decreases.

Meanwhile, as the encapsulated oil, at least one selected from vegetable oils such as mineral oil, apricot seed oil, avocado oil, castor oil and almond oil is used. Particularly, in the present invention, almondder (ALMO-NDERMIN: Laboratories Serobiologiques Co.), which is a kind of encapsulated almond oil, was used, and the encapsulated mineral oil was prepared according to the method of 3M Patent USP-5,169,632. However, such encapsulation methods do not limit the scope of the present invention.

In the present invention, the encapsulated oil is less than 5% by weight, so it is difficult to expect a sufficient makeup removal effect, and when added at 25% by weight or more, workability is inferior and oily feeling remains after washing. Preferably it is used in the range of 5-25 weight%.

The cleaning soap composition of the present invention may contain conventional ingredients used for cleansing, so that the composition contains 3 to 15% by weight of moisture. Moreover, other additives, such as antioxidant and dye, can be contained as needed.

The cleaning soap composition of this invention can be manufactured according to a conventional manufacturing method.

The cleansing soap composition according to the present invention having the above-described configuration has the characteristics of excellent clean-up effect against makeup and oil pollution while having excellent feeling and bubble power as confirmed from the results of the following experimental example.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated further more concretely based on an Example and a comparative example. However, these examples are only for the understanding of the present invention, and the scope of the present invention in any sense is not limited to these examples.

Example 1

10% by weight of distilled water, 73.0% by weight of sodium cocoyl isethionate, 10.0% by weight of soap (containing 12% of water), 1.0% by weight of ethylene oxide lauryl alcohol ether (7 molar parts of EO), encapsulated mineral oil 5.0% by weight, 1.0% by weight of fragrance was added and mixed uniformly to prepare a cleaning soap composition according to the present invention.

Comparative Example 1

10 wt% of distilled water, 79.0 wt% of sodium cocoyl isethionate, 10.0 wt% of soap (containing 12% water), and 1.0 wt% of fragrance were added to the blender, and the mixture was uniformly mixed.

The compositions of Examples 2 to 7 and Comparative Examples 2 to 6 were also prepared by mixing the materials shown in Table 1 and performing the same method as in Example 1, respectively.

The usability and makeup removal effect of the samples prepared by Examples 1 to 7 and Comparative Examples 1 to 6 were measured by the same method as in the following Experimental Example, and the results are shown in Table 2.

Experimental Example 1: Feeling Experiment

After 20 users were rinsed under the same conditions as general washing conditions, they were compared with the feelings after use. The results were evaluated and averaged. Evaluation was performed according to the following criteria.

◎: Very good (no oily feeling and soft feeling)

○: excellent (almost no oily feeling)

△: normal (slightly oily feeling)

×: bad (a lot of oil is left)

××: Very bad (a lot of oil is left)

Experimental Example 2: Makeup Removal Experiment

First, the samples prepared in Examples and Comparative Examples were diluted with distilled water to prepare an 8% aqueous solution. After accurately measuring the weight (weight A) of a 3cm × 3cm calf skin, 500 mg of the foundation was applied onto the skin, and then the weight (weight B) was measured. 1 ml of 8% sample solution was applied thereon, rubbed lightly by hand for 30 seconds, immediately rinsed with tap water for 30 seconds, dried completely, and weighed (weight C). Makeup removal rate was calculated based on the following formula from the values of weights A, B and C.

As can be seen from the above test results, when using more than 10% by weight of the non-ionic surfactant, the feeling of use is not good, the oil remains unsatisfactory, and when used less than 1% by weight, the feeling of use is excellent but the makeup removal efficiency is deteriorated. Has its drawbacks. In addition, when the encapsulated oil is used in excess of 25% by weight, the oily feeling is severe after cleansing, and in the case of using less than 5% by weight, the makeup removal efficiency is significantly reduced.

Therefore, it can be seen that it is preferable to use 1 to 10% by weight of the nonionic surfactant and 5 to 25% by weight of the encapsulated oil in order to prepare a cleaning soap having excellent usability / makeup removal efficiency.
