Description

TECHNICAL FIELD The present invention relates to oily cleansing cosmetics.

Cleansing cosmetics for removing makeup stains and sebum stains are roughly classified into water-based cleansing cosmetics called water cleansing and oil-based cleansing cosmetics called oil cleansing. Among cleansing cosmetics, oil-based cleansing cosmetics contain a large amount of oil agent, so they are compatible with make-up dirt and can exhibit excellent cleansing power. On the other hand, there is a drawback that the sticky feeling peculiar to oil remains on the skin after cleansing, and the feeling of use is poor. However, oil-based cleansing cosmetics can be said to be attractive products for those who want to thoroughly remove makeup stains.

In recent years, semi-solid to solid cleansing cosmetics called cleansing balms have attracted attention as one form of oil-based cleansing cosmetics. The cleansing balm is characterized by being very compatible with make-up stains and capable of exerting a remarkably excellent cleansing effect. In addition, the solidified oil softens on the skin when used, giving a unique feeling of melting. Such functions and usability are the reasons for its popularity. Therefore, in recent years, the development of these semi-solid cleansing cosmetics has been actively carried out.

Specifically, solid oil and liquid oil having a specific melting point, oily solid cleansing agent containing a nonionic surfactant (see, for example, Patent Document 1), and hydrocarbon oil having a specific melting point are specified. A solid oily cleansing cosmetic containing a specific amount of ester oil, a specific amount of ester oil, and a specific amount of a nonionic surfactant having a specific HLB value (see, for example, Patent Document 2), a specific amount of solid oil having a specific melting point , a specific amount of liquid oil, a specific amount of a nonionic surfactant having a specific HLB value, a specific amount of powder with a specific particle size, and an oily solid cleansing cosmetic containing a specific amount of fumed silica (for example, See Patent Document 3) and the like have been proposed.

However, since the dosage form called balm has semi-solid to solid properties, it is often filled in a jar container with a wide outlet. Therefore, there is a problem that it is troublesome to open the lid and take out the contents by tracing the surface of the agent with a fingertip every time it is used. Therefore, the idea of filling cleansing balm into a tube container, which is excellent in usability, is conceivable, but due to the act of squeezing out, which is peculiar to the tube container, excessive pressure is applied to the contents, which significantly deteriorates the stability of the balm dosage form. There was a problem that Therefore, when using a tube container, ingenuity was essential to create a formulation that does not adversely affect the stability of the formulation and the melty feeling of use peculiar to the balm.

(Sample preparation 1)
Cosmetics of Examples 1 to 8 and Comparative Examples 1 to 6 were prepared according to the conventional method according to the compositions shown in Tables 1 and 2, and subjected to the following evaluations. The results are shown in Tables 1 and 2 together.

(Test Example 1: Evaluation of formulation stability 1)
Each sample obtained in Examples and Comparative Examples was filled in a 90 g capacity jar (wide-mouthed container) and stored in a constant temperature bath at 40° C. for one week. The state of the agent after storage was visually observed and evaluated according to the following evaluation criteria. The evaluation was carried out by five professional evaluators, and the evaluations by each evaluator were comprehensively determined.

<Evaluation Criteria for Formulation Stability Evaluation 1>
○ (Good): Continuing to maintain a uniform state compared to immediately after production (no change is observed)
△ (insufficient): compared to immediately after production, a uniform state is maintained, but slight syneresis is observed × (poor): compared to immediately after production, a uniform state is not maintained, Clear syneresis is observed or does not become semi-solid

(Test Example 2: Evaluation of formulation stability 2)
Each sample obtained in Examples and Comparative Examples was filled in a 120 g volume PP tube container and stored in a constant temperature bath at 40°C. After 1 day, 4 days, and 7 days of storage, a discharge test was conducted by pressing 3 g of the composition from the tube container. The evaluation was carried out by five professional evaluators, and the evaluations by each evaluator were comprehensively determined.

<Evaluation Criteria for Formulation Stability Evaluation 2>
◯ (Good): During ejection, the uniformity of the properties similar to that immediately after production was maintained (no change was observed at all).
Δ (insufficient): A uniform state is maintained at the time of ejection compared to the properties immediately after production, but slight syneresis is observed on the surface × (poor): At the time of ejection, the properties are similar to those immediately after production In contrast, it does not maintain a uniform state, clear syneresis is observed, or it does not become semi-solid, or it cannot be discharged

In the formulation stability evaluation 2 of Test Example 2 above, each sample that gave a result of "good (good)" or "fair (unsatisfactory)" was subjected to the following tests.

(Test Example 3: Evaluation of feeling in use during spreading)
1 g of each sample was discharged onto the back of the hand soiled with lipstick, and spread with the fingertips in a small circular motion. It was sensory evaluated. The evaluation was carried out by five professional evaluators, and the evaluations by each evaluator were comprehensively determined.

<Evaluation Criteria for Usability at the Time of Spreading>
○ (Good): A feeling of use in which the semi-solid agent crumbles like it melts is obtained △ (Insufficient): A feeling of use in which the semi-solid agent crumbles like it melts is inferior × (Poor): Semi-solid shape You can't get the feeling of crumbling like a melting agent

<Evaluation criteria for familiarity with makeup>
○ (Good): Easy to blend in with makeup (dirt) without applying force to fingers △ (Poor): Need to apply some force to rub with fingers in order to blend in with makeup (dirt) × ( Poor): It is necessary to rub with considerable force in order to blend with makeup (dirt)

(Test Example 4: Evaluation during cleansing)
After applying 3 g of each sample to the entire face with make-up applied, cleansing is performed for 1 minute by drawing small circles with the fingertips, focusing on areas where make-up stains are a concern. The moisture on the face was wiped off with a towel dry.

In the usage test, "washing off" of the agent during washing and "cleansing effect" after drying with a towel were performed, and sensory evaluation was performed according to the following evaluation criteria. The evaluation was carried out by five professional evaluators, and the evaluations by each evaluator were comprehensively determined.

<Evaluation criteria for washing off>
○ (Good): Excellent in washing off △ (Insufficient): Inferior in washing off × (Poor): Poor washing off

<Evaluation criteria for cleansing effect>
○ (Good): The cleansing action sufficiently removes makeup stains △ (Insufficient): The cleansing action does not give a sufficient sensation that makeup stains have been thoroughly removed × (Poor) : Cleansing action does not give a feeling that makeup is completely removed

From the results shown in Tables 1 and 2, the oil-based cleansing cosmetics of the present invention obtained in each example had no separation or syneresis of the formulation compared to those obtained in each comparative example. It can be seen that it has remarkably excellent formulation stability. Furthermore, it can be seen that this formulation stability is exhibited not only when filled in a general jar container, but also when filled in a tube container. That is, it can be said that the oil-based cleansing cosmetic composition of the present invention can withstand excessive pressure due to the action of squeezing it out from a tube.

In addition, it can be seen that the oil-based cleansing cosmetic of the present invention produces a unique feeling of use that melts when spread, has a very good compatibility with makeup stains, and exhibits an excellent cleansing effect.

On the other hand, in Comparative Examples 1 to 6, which do not satisfy the essential constituents of the present invention, it can be seen that the unique effects of the present invention cannot be sufficiently exhibited. As is clear from these results, it can be said that the peculiar effects of the present invention can be maximized only when the essential components of the present invention are satisfied.
