Description
Technical Field
The present invention relates to a cosmetic composition for caring for/making up/cleansing/removing cosmetic products from keratin materials, such as the skin, in particular the face, the lips and/or the eyes. In particular, the present invention relates to a two-phase composition for topical application. The invention also relates to a method for caring for/making up/cleansing/removing a cosmetic product from keratin materials, such as the skin, in particular the face, the lips and/or the eyes.
Background
Compositions consisting of two separate phases, in particular an aqueous phase and an oil phase which are separate and do not emulsify together at rest, are generally referred to as "two-phase compositions". Two-phase compositions are appealing to consumers due to their aesthetic properties. They differ from emulsions in that at rest, two phases separate rather than one emulsifying in the other. Thus, the two phases are separated by a single interface at rest, however, in an emulsion, one of the two phases is dispersed in the other in the form of a plurality of droplets and thus the interface is multiple, these interfaces being usually stabilized by means of emulsifying surfactants and/or emulsifying polymers.
Two-phase compositions have been described, for example, in documents EP 0370856 and EP 0603080, in particular for removing make-up from the eyes.
Document EP 0603080 describes the use of alkyldimethylbenzyl ammonium and in particular benzalkonium chloride as a phase-separating agent for obtaining rapid phase separation.
Document EP 1514534 also describes a two-phase composition containing sodium bicarbonate as phase separating agent.
WO 2014/207259a2 discloses a two-phase composition for topical application comprising magnesium acetate.
The use of a two-phase composition requires prior shaking in order to form the emulsion. All of the above mentioned two-phase compositions are characterized by a rapid phase separation (or demixing) of the two phases.
That is, the above-mentioned two-phase composition is easily emulsified by shaking and undergoes rapid phase separation after the shaking is stopped. Sometimes the two phases separate before the consumer has finished using them, which is undesirable. In addition, after the two phases separate, the interface between them is not clear or distinct.
Thus, there remains a need for a two-phase composition consisting of two separate immiscible phases which, after shaking, will form a stable and homogeneous emulsion for a longer period of time and which has a clear interface after the two phases have separated.
Disclosure of Invention
It is therefore an object of the present invention to provide a two-phase composition for caring for/making up/cleansing/removing cosmetic products from keratin materials, such as the skin, in particular the face, the lips and/or the eyes, which composition, after shaking, will form a stable and homogeneous emulsion for a longer period of time and will have a clear interface after separation of the two phases.
Another object of the present invention is to provide a two-phase composition for caring for/making up/cleansing/removing a cosmetic product from keratin materials, such as the skin, in particular the face, the lips and/or the eyes, which composition in particular can give a clean and pleasant skin appearance (skin finish) after use and/or does not have any discomfort even around the ocular region and/or can be easily rinsed off with water or rubbed off by a cotton pad with less residue on the keratin materials.
Yet another object of the present invention is to provide a method for caring for/making up/cleansing/removing a cosmetic product from keratin materials, such as the skin, in particular the face, the lips and/or the eyes.
Thus, according to one aspect of the present invention, provided is a two-phase composition for topical application consisting of separate aqueous and oily phases, comprising, as hydrophilic gelling agent, at least one polysaccharide and at least one polycondensate of ethylene oxide and propylene oxide having formula (I):
H-(O-CH2CH2)x-(O-CH(CH3)-CH2)y-(O-CH2CH2)z-OH (I)
wherein x and z are in the range of 2-150 and y is in the range of 1-100.
According to another aspect of the present invention, provided is a method for caring for/making up/cleansing/removing a cosmetic product from a keratin material, such as the skin, in particular the face, lips and/or eyes, comprising shaking a two-phase composition as described above to form an emulsion, and applying the emulsion to the keratin material.
Surprisingly, the inventors have found that the use of a specific polysaccharide makes it possible to obtain a two-phase composition which, after shaking, can form a stable and homogeneous emulsion for a longer period of time, and that the use of a polycondensate of ethylene oxide and propylene oxide makes it possible to obtain a two-phase composition which, after separation of the aqueous and oily phases, will have a clear interface.
At the same time, the inventors have also found that the two-phase composition according to the invention can give a clean and pleasant skin appearance after use, without any discomfort even around the ocular region, and can be easily rinsed off with water or wiped off with a cotton pad with less residue on the keratin material.

The following examples are intended to illustrate the compositions, but not to limit the scope of the invention in any way. The name of a compound is given in the form of a chemical name or INCI name.
Examples
Examples 1 to 11:
the following compositions were prepared.
First, an oil phase having the following formulation was prepared (the amounts of each component are expressed in parts by weight unless otherwise specified):
| INCI name | Measurement of |
| Isohexadecane | 99.99 |
| GREEN 6 | 0.01 |
The procedure is as follows:cold mixing the components of the oil phase.
Then, different aqueous phases were prepared having the following formulation (unless otherwise indicated, the amounts of the components are expressed in parts by weight):
active material content was 30 wt%.
Poloxamer 182, poloxamer 124, poloxamer 184, poloxamer 188 and poloxamer 338 have weight average molecular weights of 2250, 2000, 3000, 9000 and 16500, respectively.
Examples 1, 3, 4, 7, 8 and 11 are outside the present invention.
For each example, 40 parts by weight of the aqueous phase was combined with 60 parts by weight of the oil to obtain the compositions of examples 1-3.
The separation time of each composition was tested after shaking was stopped and the interfacial morphology between the water and oil phases was observed after 3 minutes of separation, and the results are summarized in the table below.
| Time of separation | Interface morphology | |
| Example 1 | 45s | Clear and clear |
| Example 2 | 150s | Clear and clear |
| Example 3 | N/A | Unclear and bubbling in the oil phase |
| Example 4 | 55s | Clear and clear |
| Example 5 | 140s | Clear and clear |
| Example 6 | 160s | Clear and clear |
| Example 7 | N/A | Unclear vision |
| Example 8 | N/A | Unclear vision |
| Example 9 | 100s | Clear and clear |
| Example 10 | 120s | Clear and clear |
| Example 11 | N/A | Turbidity (haze) |
As can be seen from the above table, the composition according to the invention has a much longer separation time, while the interface is clear after the aqueous phase has separated from the oil phase.
It can also be seen that compositions comprising poloxamer 188 (example 7), poloxamer 338 (example 8) or acrylate polymers (example 11) do not have a clear interface after the aqueous phase separates from the oil phase. Compositions that do not contain polysaccharides as hydrophilic gelling agents will have shorter separation times.
When the two-phase compositions of examples 1, 3, 4, 7, 8 and 11 were applied to the skin around the eyes, it was found that the two-phase compositions according to the present invention can give a clean and pleasant skin appearance (skin finish) without any discomfort around the area of the eyes and can be easily rinsed off with water or rubbed off with a cotton pad with less residue on the skin.
While exemplary embodiments of the invention have been described above, it will of course be appreciated that many and various modifications will be apparent to those of ordinary skill in the relevant art in light of the foregoing description, or may become apparent as the technology advances. Such modifications are contemplated to be within the spirit and scope of one or more of the inventions disclosed in this specification.
