Description

[Technical Field]

[0001] The present invention relates to a two-phase composition having two visually distinguishable phases and being convertible to a single-phase composition which can be converted back into a two-phase composition. [Background technology]

[0002] A composition having two visually distinguishable phases, particularly an aqueous phase and an oily phase that do not emulsify with each other in a static state, is generally called a "two-phase" (or bi-phase) composition. This composition differs from an emulsion in that, in a static state, the two phases are separated, forming a single interface between the two phases, rather than multiple interfaces between the continuous phase and each discontinuous phase present in an emulsion.

[0003] Such two-phase compositions have already been described, for example, in EP-A-370856 and EP-A-603080, particularly in relation to makeup removal around the eyes.

[0004] During use, the two-phase composition requires mixing, such as shaking, to form a single-phase composition, such as a "temporary" emulsion, which is applied after the keratinous substance of the skin. This single-phase composition needs to provide targeted cosmetic effects, such as good makeup removal. Preferably, the single-phase composition can provide a smooth feel during application. On the other hand, after use, i.e., in a static state, the single-phase composition must return to its initial state by conversion back into a two-phase composition, known as "phase separation."

[0005] Users of the two-phase composition tend to perceive a greater moisturizing effect when the single phase formed by mixing the two phases is maintained for an extended period. Therefore, controlling the rate of "phase separation," i.e., the demulsification rate, is important.

[0006] Another important factor is the cleanliness of the package containing the two-phase composition after mixing the two-phase composition. Conventional two-phase compositions may sometimes leave some residues on the walls of the package containing the composition after mixing. The residues give the user an impression of being "dirty" or "unclean", which is not desirable.

[0007] Therefore, there is a need for a two-phase composition that has two visually distinguishable phases when not mixed and can be converted into a single-phase composition upon mixing, where the single-phase composition can provide good cosmetic effects such as good makeup removal ability, a smooth touch during application, and prevention of residue on the walls of the package containing the composition, and can return to its initial state, i.e., the two-phase composition, while controlling the demulsification rate.

[Brief explanation of the drawing]

[0025] [Figure 1] This figure shows the appearance of the package wall 30 minutes after the package containing the composition according to Example 1 has been thoroughly shaken. [Figure 2] This figure shows the appearance of the package wall 30 minutes after the package containing the composition according to Comparative Example 3 has been thoroughly shaken. [Modes for carrying out the invention]

[0026] As a result of diligent research, the inventors have discovered that it is possible to provide a two-phase composition that can be converted into a single-phase composition when mixed, which provides good cosmetic effects such as good makeup removal ability, a smooth texture during application, and prevents residue on the walls of the package containing the composition, and that can be returned to its initial state, i.e., a two-phase composition, while controlling the deemulsification rate.

[0027] Therefore, one aspect of the present invention is, (a) at least one ester oil, and (b) at least one hydrocarbon oil An oily phase containing, (c) at least one polyglyceryl fatty acid ester, and (d) water an aqueous phase containing A two-phase composition comprising, (b) The present invention relates to a two-phase composition in which the amount of hydrocarbon oil is greater than 5% by mass relative to the total mass of the composition.

[0028] The composition according to the present invention has two visually distinguishable phases when not mixed. However, when mixed, the composition according to the present invention can be converted into a single-phase composition. Single-phase compositions such as emulsions can provide good cosmetic effects such as good makeup removal ability, a smooth feel during application, and prevent residue on the walls of the package containing the composition. The single-phase composition can be converted back to a two-phase composition over time while controlling the deemulsification rate.

[0029] The composition according to the present invention is stable so that the oily phase and aqueous phase can be maintained separately when not mixed. Therefore, the two phases of the composition according to the present invention can be maintained during storage of the composition according to the present invention.

[0030] In particular, the compositions according to the present invention are stable such that their appearance and / or odor may remain unchanged for a long time under various temperature and storage conditions. For example, the compositions according to the present invention are stable at low temperatures, with or without shaking. Accordingly, the compositions according to the present invention can be stored appropriately, especially at low temperatures, even during transportation by automobile, where vibrations may occur.

[0031] When used, the compositions according to the present invention are mixed. The two phases in the compositions according to the present invention are an oily phase and an aqueous phase. Therefore, when the compositions according to the present invention are mixed, one of the two phases is dispersed in the other phase to form an O / W or W / O composition such as an O / W or W / O emulsion that is visually uniform or forms a single phase.

[0032] The mixing of the compositions according to the present invention can be easily carried out. For example, the mixing of the compositions according to the present invention can be carried out by shaking by hand. After mixing the compositions according to the present invention, the compositions form a single phase and can be maintained for a certain period of time without further mixing.

[0033] According to the present invention, a single-phase composition formed from a two-phase composition can provide good cosmetic effects, such as good makeup removal ability. Therefore, the composition according to the present invention can be used as a cosmetic composition, preferably a cleansing cosmetic composition, and more preferably a cleansing cosmetic composition for skin and eyelashes.

[0034] Furthermore, the single-phase composition formed by the two-phase composition according to the present invention can provide a good texture, such as a smooth feel. In addition, friction can be reduced. Friction can cause a relatively large loss of the outer layer of the epidermis, which can make the skin surface rough. Therefore, the composition according to the present invention can result in a smooth skin finish.

[0035] A single-phase composition formed by the two-phase composition according to the present invention may have reduced irritancy. Therefore, the composition according to the present invention may be gentle on sensitive skin, such as skin, especially the skin around the eyes.

[0036] Furthermore, after being converted into a single-phase composition, the composition can be prevented from remaining on or soiling the walls of the package containing the composition. Therefore, it is possible to maintain the cleanliness of the package containing the composition according to the present invention during use.

[0037] In addition, if the two-phase composition according to the present invention is transparent before mixing, the single-phase composition formed by mixing the two-phase composition may also be transparent.

[0038] A single-phase composition formed by the two-phase composition according to the present invention can revert to a two-phase composition after a certain period of time by undergoing phase separation and reforming into two visually distinguishable phases.

[0039] According to the present invention, the demulsification rate of a single-phase composition can be controlled. For example, it is possible to produce a single-phase composition that lasts longer. Therefore, the composition according to the present invention can provide a more moisturizing sensation. In addition, the pot life of a single-phase composition formed by the two-phase composition according to the present invention can be extended, and therefore the usefulness of the two-phase composition according to the present invention can be enhanced.

[0040] In addition, according to the present invention, the interface between the two reformed phases can be clean so that no precipitates are present at the interface.

[0041] The compositions according to the present invention are particularly useful as makeup removers, preferably for keratin fibers, and more preferably for eyelashes, i.e., for mascara.

[0238] All the numerical values for the amounts of the components shown in Table 1 are based on "mass%" as the active ingredient.

[0239] [Table 1]

[0240] [Table 2]

[0241] [Evaluation] The compositions according to Examples 1 to 6 and Comparative Examples 1 to 4 were evaluated as follows.

[0242] (Makeup removal ability) Each of the 5 panelists applied their own mascara by using a brush to apply the mascara product (MAYBELLINE Volum'Express Hypercurl Waterproof N 01 Black) to their eyelashes with a total of 40 strokes (dipping the brush into the bottle containing the mascara product each time).

[0243] 4 mL of each composition according to Examples 1 - 6 and Comparative Examples 1 - 4 was shaken to form an emulsion. The emulsion was applied onto the skin around the eyes by using a cotton sheet, by moving the cotton sheet in a circular motion around the eyes and massaging for 30 seconds.

[0244] The panelists evaluated the makeup removal ability on a scale of 1 (very poor) to 5 (excellent), and classified the average of the evaluations according to the following criteria.

[0245] Excellent (5.0 - 4.0): No residue of the mascara was observed. Good (3.9 - 3.0): Almost no residue of the mascara was observed. Poor (2.9 - 2.0): Some residue of the mascara was observed. Very poor (1.9 - 1.0): Residue of the mascara was observed.

[0246] The results are shown in Table 2.

[0247] (Transparency) The transparency of each composition according to Examples 1 - 6 and Comparative Examples 1 - 4 immediately after preparation (before shaking) was examined according to the following criteria.

[0250] (Transparency after shaking) The transparency of each composition from Examples 1-6 and Comparative Examples 1-4 was examined one week after shaking at 4°C according to the following criteria.

[0251] Excellent: Transparent Good: Slightly translucent Defective: translucent Very poor: Opaque

[0252] The results are shown in Table 2.

[0253] (Precipitates on the interface) After shaking at 4°C for one week, the presence of precipitates at the interface between the oily phase and the aqueous phase of each composition from Examples 1-6 and Comparative Examples 1-4 was investigated.

[0254] The results are shown in Table 2.

[0255] (Speed ​​of demulsification) The compositions from Examples 1-6 and Comparative Examples 1-4 were filled into clear glass bottles. The clear bottles were shaken well to form emulsions. The clear bottles were left to stand (in a stationary state), and the time until the emulsion completely disappeared and two visually distinguishable phases were formed was measured.

[0256] The results are shown in Table 2.

[0257] If the deemulsification rate is too fast, the oil / water distribution ratio will change during use, and the cosmetic performance of the composition will deteriorate. A composition that takes more than 20 minutes to deemulsify is desirable.

[0258] (Smoothness) Emulsions were formed by shaking 4 mL of each composition from Examples 1-6 and Comparative Examples 1-4. The emulsion was applied to the skin around the eyes by massaging the area with a cotton sheet in a circular motion for 30 seconds.

[0259] The panelists evaluated the smoothness of the product on the skin during application on a scale of 1 (not very smooth = friction felt) to 5 (very smooth), averaged the scores, and classified them according to the following criteria.

[0260] Excellent (5.0~4.0): Very smooth application. Good (3.9~3.0): Smooth application. Poor (2.9~2.0): Not smooth during application. Very poor (1.9~1.0): Not very smooth during application.

[0261] The results are shown in Table 2.

[0262] (stability) The compositions from Examples 1-6 and Comparative Examples 1-4 were filled into clear glass bottles. The clear bottles were kept for two months under temperature conditions of 4°C, 25°C, and 45°C. At 4°C, the bottles were kept still or shaken daily.

[0263] After two months, each composition was examined for clarity, color, and odor and evaluated according to the following criteria.

[0264] Excellent: Almost identical to the condition at the time of production. Good: Small changes were observed in terms of clarity, color, and odor. Poor: Clear changes were observed in terms of clarity, color, and odor. Either sedimentation or a cloudy appearance was also clearly observed. Very poor: Significant changes were observed in terms of clarity, color, and odor. Either sedimentation or turbidity was also observed.

[0265] The results are shown in Table 2.

[0266] (Package cleanliness) Each composition from Examples 1-6 and Comparative Examples 1-4 was filled into transparent glass bottles to be used as packaging. Each package was shaken well. The appearance of the package walls 30 minutes after shaking was examined according to the following criteria. In the following criteria, the term "residue" means droplets or films remaining on the package walls.

[0267] Excellent: No residue was observed on the inside of the package. Good: A small amount of residue was observed on the inside of the package. Defect: Some residue was observed on the inside of the package. Very poor: A large amount of residue was observed on the inside of the package.

[0268] The results are shown in Table 2.

[0269] Figure 1 shows the appearance of the package wall 30 minutes after the package containing the composition according to Example 1 has been thoroughly shaken. No residue was found on the package wall.

[0270] Figure 2 shows the appearance of the package wall 30 minutes after thoroughly shaking the package containing the composition according to Comparative Example 3 (in which the polyglyceryl fatty acid ester was removed from the composition according to Example 1). Here, a large amount of residue was observed on the package wall.

[0271] (Summary) Examples 1-6 demonstrate the use of a combination of ester oils and hydrocarbon oils in the oily phase and polyglyceryl fatty acid esters in the aqueous phase of a two-phase composition comprising an oily phase and an aqueous phase, which, when mixed to form a single-phase composition, contribute to good makeup removal ability, a smooth feel during application, and prevention of residue on the walls of the package containing the composition, and which can return to its initial state, i.e., a two-phase composition, while controlling the deemulsification rate.

[0272] Examples 1-6 also demonstrate that the compositions according to the present invention have good stability, particularly good stability at various temperatures, and transparency, whether the compositions are mixed or not, and that single-phase compositions derived from the compositions according to the present invention can be quickly reverted to two-phase compositions having a clean interface between the two reformed phases.

[0273] Comparative Example 1 shows that, compared to Examples 1-5, the makeup removal ability was reduced by not using any hydrocarbon oil.

[0274] Comparative Example 2 shows that, compared to Examples 1-5, the absence of ester oil resulted in reduced smoothness during application and a significantly faster demulsification rate.

[0275] Comparative Examples 3 and 4 show that, compared to Examples 1 and 6, the cleanliness of the packaging was reduced by not using polyglyceryl fatty acid esters.
