1. TITLE OF THE INVENTION:
AQUEOUS LIQUID/GEL PERSONAL CLEANSING COMPOSITIONS
2. APPLICANT:
Name: L’OREAL
Nationality: France
Address: L’OREAL, 14, rue Royale, F-75008 PARIS, France.
3. PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the invention and the manner in which it is to be performed:

The instant invention relates to the field of personal aqueous cleansing compositions, preferably free from any synthetic preservatives.
At this time, consumers are highly concerned with environmental safety, societal, and personal well-being impacts of products they buy as the environmental issues are increasing worldwide. This leads to a trend toward natural, organic products not only in food but also in cosmetic care products. It is concerning active materials like for example surfactants in hair and/or skin care compositions but also preservatives usually considered in these compositions to prevent bacterial and microbial degradation.
Typical examples of inorganic anti-microbial and/or anti-bacterial agents which are commercially available include those under the trade names Kathon CG (ex Rohm &Hass), Phenoxyethanol (ex Nipa Laboratories), Parabens (ex Nipa Laboratories), Germall 11 (ex ISP) and Glydant plus (ex Lonza), as well as materials such as formaldehyde. Another disadvantage of incorporating such organic anti-bacterial and/or anti-microbial compositions into cosmetic compositions is that some of them can provoke adverse skin reactions. In addition, a number of anti-bacterial and/or anti-microbial agents are suspected of toxicity.
Accordingly, there is a need for cosmetic compositions which have good cosmetic properties like enhanced mildness for example and anti-microbial and/or anti-bacterial properties, whilst at the same time being free from any usual synthetic organic anti-bacterial preservatives.
An approach to achieve this purpose has been to include in the cosmetic compositions selected herbal extracts. Thus, the patent US 5 872 087 describes a herbal dry shampoo composition, preservative free where no artificial preservative is used to increase the life of the product as the natural herb of the present composition itself acts as a preservative. The documents WO 2010/086717 and US 2012/142570 also disclose compositions comprising extracts of organically certified herbs and polyglucosides, wherein the extract is prepared employing a super critical fluid extraction or water extraction. The microbial preservation is thus achieved with organic materials including herbal extracts e.g. Aloe barbadensis, Aegle marmelose, Benincasia cerifera, Rosa centifolia, Eclipta prostrata, Glycyrrhiza glabra, Phyllanthus emblica, Terminalia chebula, and mixtures thereof and essential oils. The documents KR 2008/099093, CH 709504, KR 720381B1 and CN103789109A also disclose cosmetic products with natural ingredients, exploiting selected

herbal extracts having antimicrobial properties. Regarding the patent application CN104414928A, it discloses a handmade soap comprising natural herbal extracts, charcoal-based powder, glycerin and vegetable oils.
However, the previous compositions are essentially non-aqueous compositions or compositions containing no more than 10% of water. Accordingly, these compositions have a low « water activity ». Their risk of exhibiting microbial instability is already very low compared to compositions containing greater than 40% by weight of water like more particularly aqueous liquid/gel cleansing compositions. Furthermore, the organic anti¬bacterial and/or anti-microbial ingredients like specific herbal extracts will not be sufficiently active into such aqueous liquid/gel compositions. At last, the risk that some herbal extracts provoke adverse skin reactions if they are used in greater amounts is not zero.
Accordingly, the instant invention is intended to provide aqueous liquid/gel compositions, in particular personal skin cleansing compositions having a high water activity, free from any usual synthetic organic anti-bacterial and/or natural herbal extracts as preservatives but that, nevertheless, have high anti-microbial and/or anti-bacterial properties.
The instant invention is also directed to the identification of non-synthetic compounds which may be used as efficient preservatives in aqueous liquid/gel personal cleansing compositions without any risk of adverse reaction for the consumer.
The instant invention is also directed to the identification of non-synthetic compounds which could be used as efficient preservatives in aqueous liquid/gel personal cleansing compositions without impairing the rheological and cosmetic properties of these compositions.
In particular, the instant invention is also intended to provide stable aqueous liquid/gel personal cleansing compositions having good lathering, oil control properties suitable for the use of face and/or body wash and comprising surfactant(s). Advantageously, such compositions have to be also mild, moisturizing with respect to skin, environment friendly and biodegradable.
Unexpectedly, the inventors discovered that these purposes can be achieved by selecting at least two specific types of non-synthetic ingredients and furthermore by considering specific combinations thereof.
Thus, the instant invention advantageously discloses a novel way for microbial preservation of aqueous liquid/gel compositions i.e with high water activity, irrespective of herbal extracts and synthetic preservatives.

More particularly, the instant invention is directed to an aqueous liquid/gel personal cleansing composition which comprises at least
- a) 35% or greater by weight of an aqueous liquid medium relative to its total weight,
- b) one ose unit(s) based compound,
- c) one mineral salt and
- d) one surfactant,
said compounds b) and c) being in a weight ratio ranging from 10/10 to 40/10 and in particular around 30/10.
The instant invention is also directed to an aqueous liquid/gel personal cleansing composition which comprises at least
- a) 35% or greater by weight of an aqueous liquid medium relative to its total weight,
- b) one ose unit(s) based compound,
- c) one mineral salt, and
- d) one surfactant,
said composition having a water activity less than 0.9 preferably less than 0.87, more preferably less than 0.85, and even more preferably less than 0.81.
According to a specific embodiment, the instant invention is also directed to an aqueous liquid/gel personal cleansing composition which comprises at least
- a) 35% or greater by weight of an aqueous liquid medium relative to its total weight,
- b) one ose unit(s) based compound,
- c) one mineral salt, and
- d) one surfactant,
said composition having a water activity less than 0.9 preferably less than 0.87, more preferably less than 0.85, and even more preferably less than 0.81 and containing compounds b) and c) in a weight ratio of 30/10.

For the purpose of the present invention, the term "liquid" means in liquid form, for example the composition flows under its own weight at ambient temperature (25 °C) and atmospheric pressure in less than 5 seconds.
According to a specific embodiment, the composition of the invention has a water activity lower than 0.9.
The water activity, also called « aw » represents the partial vapor pressure of water in a substance divided by the standard state partial vapor pressure of water. This parameter is already considered in the field of food wherein the standard state is most often defined as the partial vapor pressure of pure water at the same temperature. In particular, it is known that none pathogenic bacteria is able to grow at aw as low as 0.86. Accordingly, foods that depend on water activity as a means of preservation should have a water activity of 0.85 or less.
At the knowledge of the inventors, the water activity has never been considered with respect to cosmetic products.
Unexpectedly, the inventors observed that the use of specific combinations of ose unit(s) based compound(s) and mineral salt(s) allows keeping low the water activity of aqueous liquid/gel personal cleansing products. It provides the best effect on lowering water activity, while also providing the best possible consumer sensory of the end product.
The compositions according to the invention are stable in particular they are stable at 4°C during 1 month, preferably during 2 months.
The efficiency of the combinations according to the invention is demonstrated in the following examples.
Otherwise, the claimed compositions exhibit, besides their good self-preservation property, excellent skin cleansing efficacy with sufficient care and mildness.
The cleansing compositions according to the invention are dedicated to be used as keratin material cleanser.
According to the invention, the term "keratin materials" is intended to mean the skin of the body, face and/or area around the eyes, the nails or any other area of bodily skin and also the hair.
For example the cleansing compositions according to the invention may be used as keratin material cleanser, more preferably as skin cleanser and even more preferably as facial cleanser and for example as makeup removal.

According to another aspect, the present invention also relates to a process for cleansing keratin materials, which consists in applying to said keratin materials a composition according to the present invention, eventually with water, optionally followed by rinsing it with water.
According to another aspect, the present invention is also directed to the cosmetic use of the aqueous liquid/gel personal cleansing composition as defined above, for removing makeup and/or cleansing the skin.
COMPOSITION
As the compositions of the invention are directed to be used on keratinous material and in particular on the skin, their components are contained in a physiologically acceptable liquid aqueous medium.
For the purposes of the present invention, the expression "physiologically acceptable medium" means a medium that is suitable for application of a composition according to the invention on keratinous material, such as skin.
A physiologically acceptable medium is preferably a cosmetically or dermatologically acceptable medium, that is to say a medium which is devoid of unpleasant odor or appearance and which is entirely compatible with the topical administration route.
Such a medium is in particular considered as physiologically acceptable when it does not cause the user any unacceptable stinging, tautness or redness.
The composition according to the invention comprises an aqueous medium also named aqueous phase.
The aqueous medium may consist in water alone or a mixture.
For example the aqueous medium of the composition according to the invention may comprise, in addition to water, one or more solvents selected from lower alcohols comprising from 1 to 6 carbon atoms, such as ethanol; and polyols. Suitable polyols include glycerol; glycols, for instance butylene glycol, isoprene glycol, propylene glycol and polyethylene glycols such as PEG-8; sorbitol. The amount of supplemental solvent(s) in the composition of the invention may range, for example, from 0.5% to 30% by weight and preferably from 2% to 20% by weight relative to the total weight of the composition.
In particular, a composition of the invention comprises an amount of aqueous liquid medium and preferably of water of at least 30% by weight, preferably ranging from

30% to 95% by weight and better still from 35% to 65% by weight relative to the total weight of the composition.
As stated previously, the compositions of the invention have a water activity lower than 0.9.
In the context of the invention, the "water activity" « aw » of the composition is defined as aw=p/po, where p is the measured partial pressure of the aqueous medium including soluble ingredients forming the composition and po is the standard state partial pressure of distilled deionized water.
Unless stated otherwise, all water activities are quoted are at ambient temperature. Further references to water activity (or relative humidity, where relative humidity (RH) = 100 aw) can be found in Morris, C. and s Leech, R., "Natural and Physical Preservative Systems", Curry, J., "Water Activities and Preservatives", Cosmet. Toilet. 100, 53-55, and Christian, J.H.B., "Reduced Water Activity". In:Silliker, J.H. (ed) "Microbial ecology of Foods", vol. 1, Academic Press, New York, pp 170-192.
In particular, the determination of the “water activity” of a sample can be made through the measurement of water in the sample that is available to react with or attach itself to another material. Basic design equipment for water activity measurement uses a sealed temperature controlled chamber. A sample is placed in the chamber and the chamber is sealed. The free water, i.e. the water not attached to another material is allowed to escape into the air in the chamber. After the system reaches equilibrium, the partial pressure is determined, and the ratio between this partial pressure and the standard state partial pressure of distilled deionized water is equal to the water activity aw.
An example of suitable instruments to determine water activity one can consider the instruments Labstar-aw®, LabMaster-aw Neo®, LabTouch-aw® sold by the company Novasina, the instrument sold under the name 4TE® by the company aqua lab, and the instrument Humimeter RH2® water activity meter sold by the company Schaller.
Compositions according to the invention have a water activity of less than 0.9, preferably less than 0.87, more preferably less than 0.85, and even more preferably less than 0.81.
The inventors, showed that it is possible to achieve cosmetic compositions containing at least 35% by weight of water and thus that are naturally favorable to microbiological contamination, in absence of any herbal extract or synthetic preservative.

In one particular embodiment, compositions according to the invention are thus free from anti-microbial and/or anti-bacterial synthetic agents.
In one other particular embodiment, the compositions of the invention contain less than 5 % by weight relative to their total weight of herbal extract.
According to a particular embodiment, the compositions are free of herbal extracts. For example, the compositions of the invention are free from herbal extracts like Aloe barbadensis, Aegle marmelose, Benincasia cerifera, Rosa centifolia, Eclipta prostrata, Glycyrrhiza glabra, Phyllanthus emblica and Terminalia chebula.
According to an advantageous embodiment of the invention, the compositions may be based on at least 70 % by weight in particular more than 80 % by weight relative to their total weight of natural compounds and more particularly consist in natural compounds.
According to the invention the term “natural compound” covers a product that is obtained from the earth or the soil, or from plants or animals, optionally via one or more physical processes, for instance milling, refining, distillation, purification or filtration. It also covers a “compound of natural origin” i.e. a natural compound that has undergone one or more chemical treatments that do not affect the essential qualities of this compound and/or a compound predominantly comprising natural compounds.
As stated previously, the low value of water activity is efficiently achieved according to the invention by the use of specific combinations of at least one ose unit(s) based compound and at least one mineral salt.
OSE UNIT(S) BASED COMPOUND
According to the invention an ose unit(s) based compound is a compound that consists in one or several identical or different ose units.
Among the « ose » or monosaccharide suitable for the invention, one may cite:
- trioses containing 3 carbon atoms: dihydroxyacetone, glyceraldehyde;
- tetroses containing 4 carbon atoms: erythrose, threose, erythrulose;
- pentose containing 5 carbon atoms: ribose, arabinose, xylose, ribulose, xylulose, deoxyribose;
- hexose containing 6 carbon atoms: allose, altrose, glucose, mannose, fucose, gulose, idose, galactose, talose, fuculose, psicose, fructose, sorbose, tagatose, quinovose, pneumose, rhamnose;

- heptose containing 7 carbon atoms: sedoheptulose, glucoheptose, idoheptulose, mannoheptulose, taloheptulose;
- octose containing 8 carbon atoms;
- oses containing more than 8 carbon atoms such as maltitol; in their D or L form.
Suitable ose unit(s) based compounds for the compositions of the invention are for instance sucrose, glucose, galactose, ribose, fucose, trehalose, maltose, fructose, mannose, arabinose, xylose, lactose, rhamnose and mixture thereof.
Sucrose is particularly convenient for the instant invention.
These ose unit(s) based compounds are advantageously present in the compositions of the invention under a form of an isolated compound i. e. not under the form of a product including it in mixture with other compounds.
According to a specific embodiment, a composition of the invention contains from 10% to 40% in particular from 20 to 38% by weight of ose unit(s) based compound(s) relative to its total weight.
MINERAL SALT
As representatives of mineral salts may be in particular cited salts based on sodium (Na+), potassium (K+), zinc (Zn2+), calcium (Ca2+), copper (Cu2+), iron (Fe2+), strontium (Sr2+), magnesium (Mg2+) and manganese (Mn2+), in particular their halides, especially chloride.
According to a specific embodiment, the compositions of the inventions contain NaCl sea salt as compound c).
Advantageously, the compositions of the invention contain from 5% to 15% by weight and in particular from 8 % to 12 % by weight of at least one mineral salt like NaCl relative to their total weight.
As shown in the following examples, the presence of specific combinations of such a salt with a ose unit(s) based compound allows to achieve aqueous compositions having a low water activity.

More particularly, the compositions of the invention contain ose unit(s) based compound(s) and salt(s) like NaCl in a weight ratio ranging from 10/10 to 40/10 and more particularly about 30/10 W/W.
According to a specific embodiment, the compositions of the inventions contain respectively sucrose and NaCl sea salt as compounds b) and c).
According to a specific embodiment, the compositions of the invention contain sucrose and NaCl in a weight ratio of 30/10 W/W.
As shown by the inventors, while a solution of mineral salt like NaCl at 10 % w/w has alone a water activity of 0.94; and the solution of sucrose at 30 % w/w alone has a water activity of 0.96; the combination of both natural compounds at a weight ratio 30 % w/w of ose unit(s) based compound for 10 % w/w of mineral salt unexpectedly allows to achieve a reduction of the water activity of 0.82 or even below depending on other ingredients on the formulation.
SURFACTANT
As stated previously, the claimed compositions contain one or several surfactant(s). In particular, the compositions of the invention may contain from 0.1 % to 70 % by weight in particular from 0.5% to 20%, better from 2% to 10% and more preferably from 3 % to 8 % by weight of surfactant(s) relative to their total weight.

Table 2
Results displayed in table 2 experiment 1 have been obtained considering either one of two sucroses commercially available: the product sold under the name Refined Sugar by the company Godavari Biorefineries and the product sold under the name CT Organic Sugar Golden Light by the company Gebana.
Results displayed in table 2 experiment 2 have been obtained considering either one of two glucose powders commercially available: the product sold under the name Dextrose Monohydrate ST by the company Roquette and the product sold under the name Cerelose 02001 by the company STE Products MAIS.
These data show that the combination of sucrose with NaCl in a ratio as required according to the invention allows to obtain a water activity lower than 0.86 i.e. a value lower than the value achieved with NaCl when used alone at a greater concentration i.e. greater than 22% by weight.
