Abstract

The invention relates to a composition for topical application, constituted of a hydrophilic phase and of an oily phase that are separate and transparent, the hydrophilic phase comprising at least 40% by weight of one or more polyols relative to the weight of the hydrophilic phase and the oily phase comprising at least 5% by weight of one or more non-silicone oils relative to the weight of the oily phase, the amounts of polyols and of non-silicone oils being such that the refractive indices of the oily and hydrophilic phases are substantially equal, said composition comprising less than 4% by weight of silicone oils relative to the total weight of the composition and the amount of surfactant in the composition being less than or equal to 2% by weight relative to the total weight of the composition. The two separate phases are transparent and have a clear interface, and, on agitating, these two transparent phases form a single phase that is also transparent.

Description

Silicone-free transparent: two-phase composition

One subject of the present invention is a composition for topical application, constituted of two separate phases, a hydrophilic phase and an oily phase, that emulsify readily by agitation giving a clear, that is to say transparent, composition, and the use of said composition for makeup removal, cleansing and/or care of the skin, lips and/or eyes, and/or for care of the hair.

The compositions of this type constituted of two separate phases, especially of a hydrophilic aqueous phase and of an oily phase, are generally referred to by the term "two-phase composition". They differ from emulsions by the fact that at rest the two phases are separate instead of being emulsified in one another. Thus, the two phases are separated at rest by a single interface whereas, in emulsions, one of the phases is dispersed in the other in the form of a multitude of droplets, and the interfaces are therefore multiple, these interfaces generally being stabilized by emulsifying surfactants and/or emulsifying polymers. The use of two-phase compositions requires prior agitation in order to form an extemporaneous emulsion. This must be of sufficient quality and stability to allow a homogeneous application of the two phases, but such that at rest, the two phases rapidly separate and regain their initial state, this phenomenon being better known by the term "phase separation".

Two-phase compositions have already been described, for example, in documents EP-A-370 856 and EP-A-603 080, especially for removing makeup from the eyes.

A number of these two-phase compositions form, after agitation, an opaque emulsion, a mixture of two phases that are immiscible in one another. However, these compositions are generally presented in transparent containers, and the opacity of the two emulsified phases is aesthetically harmful. Moreover, it is increasingly sought to use transparent compositions because, just like water, the transparency is a symbol of purity and therefore of cleanliness, and transparent compositions are thus particularly appreciated by the users.

The use, in two-phase compositions, of silicone oils such as for example cyclopentasiloxane make it possible to obtain compositions that form, after agitation, a transparent mixture of two immiscible phases.

However, it is difficult, or even impossible, to obtain a transparent mixture when the two phases are not miscible, without using silicone oils.

Consumers are increasingly seeking cosmetic products formed from/that comprise natural constituents or constituents of natural origin, in particular products that do not comprise silicone compounds. There is therefore still a need for a two-phase composition constituted of two separate immiscible phases which, after agitation, gives a transparent emulsion, while retaining the properties desired for two-phase compositions, that is to say a rapid phase separation into two transparent phases and which is substantially free of silicone compounds.

Surprisingly, the Applicant has found that it was possible to obtain a transparent two-phase composition which, after agitation, gives a transparent emulsion and which phase separates again rapidly into two transparent phases, having a perfectly clear interface, by using a hydrophilic phase comprising one or more polyols in a sufficient amount and an oily phase comprising one or more non-silicone oils in a sufficient amount.

More particularly, one subject of the invention is a composition for topical application, constituted of a hydrophilic phase and of an oily phase that are separate and transparent, the hydrophilic phase comprising at least 40% by weight of one or more polyols relative to the total weight of the hydrophilic phase and the oily phase comprising at least 5% by weight of one or more non-silicone oils relative to the total weight of the oily phase, the amounts of polyols and of non-silicone oils being such that the refractive indices of the oily and hydrophilic phases are substantially equal, said composition comprising less than 4% by weight of silicone oils relative to the total weight of the composition and the amount of surfactant in the composition being less than or equal to 2% by weight relative to the total weight of the composition .

Since the composition according to the invention is intended for a topical application, it contains a physiologically acceptable medium, that is to say a medium that is compatible with the skin, the mucosae, the hair and the scalp.

The composition according to the invention comprises at least one hydrophilic phase and one oily phase that are separate. These two phases are separate, that is to say that they are visible, one on top of the other, at rest, and the interface between the two is perfectly clear. They are transparent at rest, and when the composition is agitated before it is used, the mixture obtained constituted of the emulsion of one phase in the other is transparent. The two phases may or may not be coloured. Moreover, the use of a relatively high polyol content makes it possible to be partially or completely free of the presence of preservatives in the composition according to the invention.

The refractive indices of the hydrophilic phase and of the oily phase are substantially equal, the word "substantially" meaning that the difference between the refractive indices of the two phases does not exceed 0.005 and therefore that the refractive indices of the two phases are equal to within 0.005. The refractive indices of these phases are generally of around 1.39 to 1.48, these indices being measured at ambient temperature (20 to 25°C) .

The word "transparent" means that the composition has a turbidity of less than or equal to 300 NTU. The transparency of a composition can be measured by its turbidity, and the NTUs (nephelometric turbidity units) are the units for measuring the turbidity of a composition. The turbidity measurement may be carried out, for example, with a 2100P model turbidimeter from Hach Company, the tubes used for the measurement having the reference AR397A cat 24347-06. The measurements are carried out at ambient temperature (20⁰C to 25°C) . The composition of the invention has a turbidity generally ranging from 2 to 300 NTU, and preferably from 5 to 200 NTU.

Hydrophilic phase

The hydrophilic phase of the composition according to the invention comprises at least 40% of polyols relative to the total weight of the hydrophilic phase. Thus, the amount of polyols is preferably at least 10 by weight relative to the total weight of the composition and it may range, for example, from 10 to 90% by weight and preferably from 15 to 50% by weight relative to the total weight of the composition. The term "polyol" should be understood to mean any organic molecule comprising at least two free hydroxyl groups. As polyols, mention may be made, for example, of glycerol, glycols such as butylene glycol, propylene glycol, isoprene glycol, dipropylene glycol, hexylene glycol and polyethylene glycols, sorbitol, sugars such as glucose, and mixtures thereof. According to one preferred embodiment of the invention, the polyol chosen is glycerol, dipropylene glycol or mixtures thereof, or a mixture of glycerol and/or of dipropylene glycol and of one or more other polyols especially chosen from those indicated above: butylene glycol, propylene glycol, isoprene glycol, hexylene glycol, polyethylene glycols, sorbitol, sugars, methylpropanediol and 1, 3-propanediol and mixtures thereof.

Besides the polyols, the hydrophilic phase of the composition according to the invention may comprise water and any water-soluble or water-dispersible additive. The water used may be sterile demineralized water and/or a floral water such as rose water, cornflower water, camomile water or lime water, and/or a natural thermal or mineral water such as, for example: water from Vittel, water from the Vichy basin, water from Uriage, water from La Roche Posay, water from La Bourboule, water from Enghien-les-Bains, water from Saint Gervais-les-Bains, water from Neris-les- Bains, water from Allevar-les-Bains, water from Digne, water from Maizieres, water from Neyrac-les-Bains, water from Lons-le-Saunier, water from Eaux Bonnes, water from Rochefort, water from Saint Christau, water from Les Fumades, water from Tercis-les-Bains or water from Avene . The hydrophilic phase may also comprise reconstituted thermal water, that is to say a water comprising trace elements such as zinc, copper, magnesium, etc., reconstituting the characteristics of a thermal water.

The hydrophilic phase may also comprise a primary alcohol, that is to say an alcohol comprising from 1 to 6 carbon atoms, such as ethanol and isopropanol. This is preferably ethanol. This alcohol may be present in an amount ranging, for example, from 0.01 to 40% by weight and preferably from 0.1 to 25% by weight relative to the total weight of the composition. The addition of such an alcohol may be especially appropriate when the composition according to the invention is used as a product for the body or the hair .

Preferably, the weight ratio between the hydrophilic phase and the oily phase ranges from 25/75 to 90/10, preferably from 30/70 to 70/30, better still from 40/60 to 60/40 and even better still from 45/55 to 55/45. The hydrophilic phase therefore generally represents from 25 to 90% by weight, preferably from 30 to 70% by weight, better still from 40 to 60% by weight and even better still from 45 to 55% by weight relative to the total weight of the composition. Oily phase

The oily phase generally represents from 10 to 75% and preferably from 30 to 70% by weight, better still from 40 to 60% by weight and even better still from 45 to 55% by weight relative to the total weight of the composition . The oily phase of the composition according to the invention comprises at least 5% of one or more non- silicone oils relative to the total weight of the oily phase. Relative to the total weight of the composition, the amount of non-silicone oil (s) is preferably at least 1% by weight, and this amount may range, for example, from 1 to 70% by weight, preferably from 5 to 65% by weight, better still from 10 to 60% by weight and even better still from 20 to 60% by weight relative to the total weight of the composition. The composition according to the invention comprises less than 4% by weight of silicone oils relative to the total weight of the composition, preferably less than 3%, more preferably less than 2%, better still less than 1% by weight and even better still less than 0.5% by weight of silicone oils. In particular, it is free of silicone oils.

Example 1: Makeup-removing compositions

Procedure: The constituents of the oily phase on the one hand and those of the aqueous phase on the other hand are mixed. Then the two phases are mixed.

Compositions are obtained which, at rest, comprise an aqueous phase and an oily phase that are separate, coloured and transparent. By shaking, the two phases give a transparent composition that has a clear interface and a demixing time that allows good removal of makeup from the skin, lips and eyes. Exam le 2: Anti-UV suntan com ositions

Procedure: The constituents of the hydrophilic phase on the one hand and of the lipophilic phase on the other hand are mixed, then the two phases are mixed, these operations being carried out at ambient temperature .
