Description

COMPOSITION COMPRISING AT LEAST ONE GLYCOLIPID, AT LEAST ONE LINEAR OR BRANCHED LIQUID FATTY ALCOHOL AND AT LEAST TWO POLYSACCHARIDES, USE AND PROCESS USING THE COMPOSITION

Technical field

The present invention relates to the field of cosmetic products, notably intended for reducing the appearance of skin blackheads and/or for preventing skin blackheads.

More particularly, the present invention is directed towards proposing a composition comprising at least one glycolipid, at least one linear or branched liquid fatty alcohol comprising from 6 to 18 carbon atoms and at least two different polysaccharide polymers. The invention also relates to the use of a composition for reducing and/or inhibiting and/or preventing the appearance of blackheads on keratin materials such as the skin.

The invention also relates to a cosmetic process for caring for keratin materials, such as the skin, in particular for reducing and/or inhibiting and/or preventing the appearance of blackheads, comprising the topical application to the skin of a composition as described previously.

For the purposes of the present invention, the term “skin” is understood to denote all of the skin of the body, excluding the scalp and the mucous membranes. Preferably, the term “skin” targets the skin of the face and/or of the hands, in particular the skin of the face, more particularly the skin of the forehead and/or of the alae of the nose and/or of the chin.

Prior art

There exist cosmetic compositions for combating the appearance of skin blackheads or for concealing them, in particular on the face. This type of cutaneous imperfection, which concerns all skin typologies, is generally considered to be unattractive and thus undesirable. In view of its black, indeed even brown, colour, it is regarded as overly visible, all the more so on a lightly pigmented skin.

To date, the source of the colour of skin blackheads has not been fully established.

It is, on the other hand, known that skin blackheads result from the process of comedogenesis which affects the pilosebaceous units of sebaceous follicle type, which are predominantly distributed on the face. From a clinical perspective, a skin blackhead is thus an open comedone (non-inflammatory lesion) characterized by distension of the hair canal, sebum retention and excessive cornification of the pilosebaceous duct. Hypercornification is considered to result in sebum retention and in the accumulation of cell debris.

A certain number of solutions for treating skin blackheads have already been proposed.

Some of these solutions are based more particularly on treating blackheads with an active agent that is capable of preventing, altering or eliminating the blackheads. By way of illustration of these active agents, mention may notably be made of active agents that are capable of dissolving the lipids constituting the blackheads, such as the alkyl lactate derivatives described in patent US 4 540 567, the lipase enzyme, described in patent application US 2006/051339, or else neutralized fatty acids as described in patent application EP 3 150 187.

However, a number of these active agents have the drawback of impairing the properties of the composition comprising them, in particular the odour and/or colour of the composition, over time. These active agents also prove to be effective only with regard to blackheads that have already appeared.

One of the solutions proposed for overcoming these drawbacks is the use of glycolipids in the compositions.

Specifically, it has been found that glycolipids, and notably dirhamnolipids, inhibit the formation of skin blackheads, probably by intervening in the process of oxidation of L- DOPA (3,4-dihydroxy-L-phenylalanine). As a reminder, L-DOPA is involved in the very complex melanogenesis mechanism. More specifically, the oxidation of L-DOPA, promoted by the microbial activity present in the comedone, is expressed by a colouring effect probably of dopachrome type, the latter being a coloured intermediate of the melanin biosynthesis pathway. The dirhamnolipids appear to impair the formation of the product of the oxidation reaction in the comedones and thus inhibit their black or brown colouration. Such compounds have already been used in cleansing compositions, described in patent application WO 2020/114793, notably for cleansing cosmetic residues, undesirable microorganisms or the body’s own excretions such as sebum.

However, the use of such active agents requires the presence of a high surfactant content, which has the drawback of making the composition opaque. This aspect is often regarded as offputting by consumers. Specifically, opalescence or translucency is a particularly sought-after and appreciated effect which corresponds to a current trend.

One solution would then be to reduce the surfactant content in such compositions. However, this reduction leads to a loss of stability in the formulations over time, with the appearance of creaming and syneresis.

Furthermore, consumers are nowadays very sensitive with regard to the environmental impact of the products used.

Consequently, it remains very difficult to use glycolipids in cosmetic compositions, while retaining satisfactory sensory results, and with the least possible environmental impact.

Disclosure of the invention

The aim of the present invention is to solve the abovementioned technical problems.

In the light of the foregoing, it is thus clear that the need remains to provide consumers with novel cosmetic compositions containing glycolipids, which are effective in preventing and/or cosmetically treating skin blackheads and which have both good stability over time and good sensory properties, notably softness and little or no tack after application.

There is also a remaining need for such compositions to be fluid.

The need also remains to have compositions that are compatible with the current consumer demands, notably regarding the environment.

The present invention is specifically directed towards meeting these needs.

Summary of the invention

Thus, according to a first aspect, the present invention relates to a composition, notably a cosmetic composition, in particular for caring for keratin materials, comprising:

- at least one glycolipid;

- at least one linear or branched liquid fatty alcohol comprising from 6 to 18 carbon atoms;

- at least one polysaccharide polymer chosen from non-starchy heteropolysaccharides; and

- at least one polysaccharide polymer different from non-starchy heteropolysaccharides.

As illustrated in the examples hereinbelow, the Applicant has discovered, surprisingly, that by combining specific polymers with glycolipids, in the presence of a particular fatty alcohol, it is possible to obtain effective, stable, fluid and opalescent compositions with good cosmetic properties. This discovery forms the basis of the present invention. The invention also relates to a skincare process, in particular for reducing and/or inhibiting and/or preventing the appearance of blackheads, characterized in that it comprises the application to the skin of a composition as defined previously.

A subject of the present invention is also the use of a composition as described previously for reducing and/or inhibiting and/or preventing the appearance of blackheads on keratin materials such as the skin.

Other characteristics, aspects and advantages of the invention will emerge on reading the detailed description that follows.

Detailed description

The composition according to the invention is cosmetic and/or dermatological, and preferably is cosmetic.

The composition according to the invention is generally suitable for topical application to the skin and thus generally comprises a physiologically acceptable medium, i.e. a medium that is compatible with the skin.

The term "cosmetic" refers to a composition that is compatible with the skin, mucous membranes and the integuments. The composition according to the invention is non- therapeutic.

It is preferably a cosmetically acceptable medium, i.e. a medium which has a pleasant colour, odour and feel and which does not cause any unacceptable discomfort, i.e. stinging, tautness or redness, liable to discourage the user from applying this composition.

As mentioned previously, the composition according to the invention comprises at least one glycolipid.

In particular, the composition according to the invention may comprise a mixture of at least two, in particular at least three glycolipids.

If two or more glycolipids are used, they may be identical or different.

The term “glycolipid” means a compound formed from a lipid to which are attached one or more sugar compounds.

In particular, the glycolipid(s) may be chosen from rhamnolipids, sophorolipids, glucolipids, trehalolipids, cellobiose lipids and mixtures thereof. Preferably, the glycolipid(s) are chosen from rhamnolipids, sophorolipids and mixtures thereof, and more preferentially from rhamnolipids.

Cosmetic composition

The composition used according to the invention may be in any presentation form normally used in the cosmetics field.

It may notably be in the form of an aqueous or aqueous-alcoholic solution, which may be gelled, a dispersion of the lotion type, which may be a two-phase dispersion, an oil-in- water or water-in-oil emulsion or a multiple emulsion, an aqueous gel, or else a dispersion of oils in an aqueous phase, notably using spherules, it being possible for these spherules to be polymeric particles or, better still, lipid vesicles of ionic and/or nonionic type. The composition may be of more or less fluid liquid consistency.

According to a preferred variant, the composition considered according to the invention differs from compositions having an essentially detergent purpose with regard to the skin, hair and/or mucous membranes, such as soaps, shampoos and shower gels for washing and/or cleansing.

The composition according to the invention may comprise any constituent usually employed in the envisaged topical application and administration.

The composition according to the invention may advantageously be in the form of an emulsion, notably obtained by dispersion of an aqueous phase in a fatty phase (W/O) or of a fatty phase in an aqueous phase (O/W), of liquid or semi-liquid consistency of the milk type, or of soft consistency, or even of multiple emulsion (W/O/W or O/W/O). These compositions are prepared according to the usual methods.

More particularly, this composition is intended for topical application and preferably is in the form of an emulsion, preferably an oil-in-water emulsion. Preferably, such an emulsion is not intended to be rinsed off after application.

The composition according to the invention is intended to be applied to the skin.

Preferably, the skin is the skin of the face and/or of the body, in particular of the face and/or of the hands, preferably of the face, and more particularly of the forehead and/or of the alae of the nose and/or of the chin.

The pH of said composition is advantageously less than or equal to 8, preferably ranging from 4 to 7, better still ranging from 4.5 to 6.5.

As specified, it is advantageously in the form of an oil-in-water emulsion, which is advantageously very fluid.

The composition may alternatively be in the form of a face and/or body care or makeup product, and may be packaged, for example, in the form of a cream in a jar or a fluid in a tube or a pump bottle or a dropper bottle.

The composition according to the invention may be manufactured via any known process generally used in the cosmetics field. The ingredients are mixed, before being formed, in the order and under conditions that may readily be determined by a person skilled in the art.

According to a particular form of the invention, other agents intended to enhance the appearance and/or the texture of the skin may also be added to the composition according to the invention.

Uses and processes

According to one of its aspects, the present invention relates to the use of a composition as defined previously for reducing and/or inhibiting and/or preventing the appearance of blackheads on keratin materials such as the skin.

According to another of its aspects, the present invention relates to a cosmetic process for caring for keratin materials, such as the skin, in particular for reducing and/or inhibiting and/or preventing the appearance of blackheads, comprising at least one step in which a composition as defined previously is applied to said keratin materials.

The cosmetic uses and processes considered according to the invention are non-therapeutic. The cosmetic use or process of the invention is performed by topically administering a composition according to the invention.

The topical administration consists of the external application to the skin of cosmetic compositions according to the usual techniques for the use of these compositions.

By way of illustration, the cosmetic use or process according to the invention may be performed by topical, for example daily, application of at least one composition according to the invention, which may be formulated, for example, in the form of a cream, gel, serum, lotion, emulsion, makeup-removing milk or after-sun composition, preferably in emulsion form.

According to one embodiment, the application is repeated, for example, 1 to 2 times daily for one or more days and generally over an extended period of at least 4 weeks, indeed even 4 to 15 weeks, with, if appropriate, one or more periods of stoppage.

According to one embodiment, the application is daily (once a day) and generally over an extended period of at least 4 weeks, indeed even 4 to 15 weeks, with, where appropriate, one or more periods of stoppage.

According to one embodiment, the composition according to the invention will be applied to areas of skin that have been cleansed beforehand, for example using an appropriate soap, and/or freed beforehand of blackheads, for example using an adhesive patch or a mechanical action.

According to an embodiment variant, the composition according to the invention will be applied to areas of skin that have been previously cleansed using a washing solution.

Moreover, treatment combinations optionally with topical forms may be envisaged, so as to complement or reinforce the activity of the composition according to the invention

A topical treatment with the composition according to the invention, combined with an ancillary composition intended for topical application, is conceivable.

Thus, the present invention relates in particular to a cosmetic process for reducing and/or inhibiting and/or preventing the appearance of blackheads, comprising: a) a step of topical application to the skin of a washing solution; b) a step of topical application to the skin of a composition according to the invention, notably in the form of an oil-in-water emulsion; and c) optionally, a step of topical application of a composition different from the composition applied in step b), it being possible for steps b) and c) to be performed simultaneously or successively.

Such a composition applied in step c) can be termed a “supplementary composition”.

The washing solution may notably be in various forms, such as a solution, an aqueous solution, a lotion, a milky lotion, a cream, a gel, a liquid gel, a paste, a serum, a suspension, a dispersion, a fluid, a milk, an emulsion (O/W or W/O form), or others, preferably in the form of a solution or an aqueous gel.

MATERIALS AND METHODS

Stability measurement

The stability of the compositions may be evaluated according to the following protocol. The properties of the composition to be tested are evaluated immediately after its preparation.

The composition to be tested is then stored for 2 months at various temperatures: room temperature (about 20°C), 4°C, 37°C and 45°C. The temperature may be regulated using an oven, for example Firlabo’s Bio Concept machine.

The properties are evaluated after 1 month and 2 months of storage under the conditions described above.

The properties evaluated are:

- the pH of the composition using a pH-meter;

- the viscosity of the composition, measured with a viscometer, for example a Rheomat RM 100 viscometer from Lamy Rheology according to the CID-012-02 method;

- the appearance of the composition, in particular its microscopic appearance evaluated by observation of the composition under a microscope between slide and coverslip, at XI 0 magnification;

- the colour and odour of the composition; and

- the leaching, creaming, coalescence, formation of a surface film, mottling, etc.

The closer the properties of the composition after 1 month and/or 2 months of storage remain to those initially measured, the more the composition may be considered as remaining stable.

In particular, if the composition remains smooth and homogeneous, with no leaching, no phase separation and no change in colour, then it is considered to be stable.

Measurement of the sensory effect

The sensory effect is evaluated by scoring the performance of the composition according to tackiness on a scale ranging from 1 (non-tacky) to 5 (very tacky).

To do this, 50 pL of the composition to be tested are taken up using an Eppendorf micropipette fitted with a 0.5 mL combitip, then deposited on one half of a Skin FX support (Reference: Sheet Medium Back K6 Languette from Axon Cable SAS) applied to the back of the hand. The composition is then spread by hand, using approximately 15 rotations, twice at 15- second intervals. The composition thus spread is left to dry for 120 seconds and the fingers are rinsed with a cloth moistened with warm water.

The tack is evaluated using the index and middle fingers after each 15-rotation phase and then after drying.

Between two evaluations, the fingers are rinsed using a cloth moistened with warm water. The study is performed by a panel of five experienced people who evaluate the tack individually according to the above protocol.

The result is expressed as the average of the scores obtained, rounded to the nearest halfunit, according to the following scale:

- score < 3 : sparingly or not at all tacky;

- score equal to 3 : medium tack;

- score > 3: very tacky.

According to the invention, a composition is considered to be unacceptably tacky if its average score according to the above protocol is greater than or equal to 3.0.

Measurement of glidance/softness

The playtime evaluation consists in noting the performance of the composition in terms of glidance/softness on a scale ranging from 1 (not at all glidant/soft) to 5 (very glidant/soft). To do this, 50 pL of the composition to be tested are taken up using an Eppendorf micropipette fitted with a 0.5 mL combitip, then placed on a Skin FX support (Reference: Sheet Medium Back K6 Languette from Axon Cable SAS) applied to the back of the hand. The composition is then spread by hand, using approximately 15 rotations, twice at 15- second intervals. The composition thus spread is left to dry for 120 seconds and the fingers are rinsed with a cloth moistened with warm water.

The glidance/softness is evaluated using the index and middle fingers after drying. Between two evaluations, the fingers are rinsed using a cloth moistened with warm water. The study is performed by a panel of five experienced people who individually evaluate the glidance/softness according to the above protocol.

- score < 3: sparingly or not at all glidant/soft;

- score equal to 3: average glidance/softness; - score > 3: glidant/soft.

According to the invention, a composition is considered glidant/soft if its average score according to the above protocol is greater than or equal to 3.0.

Viscosity measurement

The viscosity of the compositions may be measured using a rheometer (Rheomat RM200). The measurement is performed using an immersed element (spindle or measuring body) rotating at a constant chosen speed. The measurement is performed with a product to be analysed - cup - measuring body assembly at a given nominal temperature, regulated for example using a thermostatic bath. The measuring cup is filled with the composition to be tested, avoiding the introduction of air and pouring along the wall.

The spindle used for performing the measurements is chosen depending on the viscosity of the product to be analysed:

- Ml : lotion;

- M2: fluid milk;

- M3: cream, thick milk; and/or

- M4: thick cream, preferably M2.

The machine is programmed to perform 75 measurements, at a spindle rotation speed of 200 rpm. The nominal temperature is 25°C. The viscosity is measured after 10 minutes of rotation of the measuring body.

The results are expressed in Pa.s.

A composition may be considered to be fluid if it has a viscosity of less than or equal to 0.65 Pa.s as measured according to the protocol defined above.

EXAMPLE 1 of the

A composition according to the invention (II), and two compositions outside the invention (Cl and C2) not comprising non-starchy heteropolysaccharides, were prepared. These compositions, in the form of oil-in-water emulsions, comprise the compounds detailed in Table 2 below, in contents expressed as weight percentages relative to the total weight of the composition. [Table 2]

Preparation protocol

In a tank, the components of phase Al are heated to a temperature of 75°C with paddle stirring until a perfectly homogeneous medium is obtained. The components of phase A2 are dispersed in this heated mixture using a rotor/ stator until a perfectly homogeneous, gel- free medium is obtained. The components of phase B are dispersed in the mixture using a rotor/stator until a perfectly homogeneous medium is obtained. The components of phase C are added and homogenized using a rotor/stator, with cooling at a temperature of 25 °C. The components of phase D are dispersed using a rotor/stator until a homogeneous medium is obtained, while keeping the temperature at 25°C. Finally, the components of phase E are added with paddle stirring until a homogeneous mixture is obtained.

EXAMPLE 2 Results The stability, sensory effect and viscosity of composition II according to the invention and of compositions Cl and C2, outside the invention, were evaluated according to the measurement protocols detailed above.

The results are collated in Table 3 below. [Table 3]

Composition II according to the invention is stable, in the sense that no significant change in its properties is observed, even after storage for 2 months at 45°C.

Composition Cl, on the other hand, shows phase separation and sedimentation of the fillers after 2 months of storage at 45°C and is thus unstable.

Moreover, composition II according to the invention is advantageously sparingly or not at all tacky, unlike composition C2, outside the invention, which is unacceptably tacky.

As a result, the composition according to the invention, comprising at least one polysaccharide polymer chosen from non-starchy heteropolysaccharides and at least one polysaccharide polymer different from non-starchy heteropolysaccharides, has both particularly advantageous stability and texture, compared with a composition comprising only a non-starchy heteropolysaccharide.

Finally, a composition according to the invention has a fluid texture. EXAMPLE 3

A composition according to the invention (II) and a composition outside the invention (C3) not comprising any linear or branched liquid fatty alcohol comprising between 6 and 18 carbon atoms, were also prepared, according to the preparation protocol described above. These compositions, in the form of oil-in-water emulsions, comprise compounds with contents expressed as weight percentages relative to the total weight of the composition and are detailed in Table 3 below.

[Table 4]

EXAMPLE 4

Results The stability and sensory effect of composition II according to the invention and of composition C3 outside the invention were also evaluated according to the measurement protocols detailed above.

The results are collated in Table 5 below. [Table 5]

On the other hand, composition C3, which is outside the invention, shows leaching of oil on the surface after 2 months of storage at 45°C and is thus unstable.

In addition, there is a significant superiority in the perception of the glidance/softness of composition II according to the invention compared with composition C3.

As a result, the composition according to the invention, comprising at least one glycolipid and at least one linear or branched liquid fatty alcohol comprising between 6 and 18 carbon atoms, in particular at least oleyl alcohol, has both advantageous stability and advantageous sensory properties, compared with a composition not comprising any linear or branched liquid fatty alcohol comprising between 6 and 18 carbon atoms.
