Description

Title of the invention: Plant extract comprising polyisoprenes

[0001] The present invention relates to a plant extract comprising at least one polyisoprene A with an average molecular mass in the range of 1 kDa to 15 kDa and at least one polyisoprene B with an average molecular mass in the range of 80 kDa to 150 kDa and its method of obtaining.

[0002] The invention also relates to the use of said extract in the fields of cosmetics, pharmaceuticals, coatings, inks, varnishes, paper, adhesives, candles, plastics, rubbers and / or food products.

[0003] Paraffins, also called mineral waxes, are hydrocarbon compounds derived from petroleum refining. Composed of linear and branched cyclic alkanes with 18 to 60 carbon atoms, respectively iso- and cycloalkanes, paraffins are substances with a solid to semi-solid consistency at room temperature (Bio-paraffin from Soybean OH as Eco-friendly Alternative to Mineral Waxes. Sandra Romero et al. Ind. Eng. Chem. Res. 2021, 60, 5364-5373). Their main properties are their variable melting point, ranging from 35 to 90°C, their excellent oxidation and temperature stability, their odorless nature, and their clarity.

[0004] Different types of mineral paraffins are distinguished according to their consistency and melting point: soft waxes, microcrystalline waxes, and paraffin waxes, respectively better known by their English names slack wax, petrolatum, microcrystalline wax, paraffin wax, ozokerites, and Fisher-Tropsch wax. The applications of mineral paraffins are extremely wide-ranging, as they are widely used in the fields of packaging and cardboard manufacturing in particular (more than 30% of production volumes), candles (25% of volumes), inks and coatings (more than 10% of volumes), plastics and rubbers (8%), adhesives (8%), and cosmetics (An Example of Commercializing Biobased Coatings and Binders. D. Jarboe. Written for presentation at the 2017 ASABE Annual International Meeting Sponsored by ASABE, Spokane, Washington, July 16-19, 2017).

[0005] Many of these markets are also served by certain so-called natural waxes of vegetable or animal origin, such as beeswax, candelilla wax, and carnauba wax. Although more expensive, these waxes offer a renewable alternative to mineral paraffins. Their main common characteristic is their melting or dropping point, which is between 40 and 90°C (The World of Wax. M. Becker. Oils & Fats International (OF1), January 2010, pp. 38-40). However, their global production volume of 400,000 tonnes remains far lower than that of mineral paraffins, estimated at over 3 millions of tons.

[0006] However, mineral paraffins and natural waxes do not meet certain recent market expectations, particularly in terms of environmental friendliness and safety. These waxes and paraffins are also facing increasing regulatory challenges.

[0007] Thus, a significant group of mineral paraffins is suspected of toxicity, particularly carcinogenic effects. Therefore, in 2013, the EFSA (European Food Safety Authority) established acceptable daily intakes for microcrystalline waxes (food additive E 905) and medium-viscosity white paraffins, applicable to a wide range of food products (Scientific Opinion on Minerals or Hydrocarbons in Food, EFSA Panel on Contaminants in the Food Chain (CONTAM), published on 28 August 2013). This resulted in maximum concentration limits to be observed, particularly in dairy products, vegetable oils, cereals, spices, fish, eggs, etc.

[0008] Furthermore, due to their origin, mineral paraffins contribute negatively to the increase of anthropogenic carbon dioxide. In addition, they are not biodegradable and induce bioaccumulation in the environment (Waxes and Related Materials. American Petroleum Institute. January 21, 2011). This is why many sectors are seeking substitutes of natural and renewable origin.

[0009] Finally, recent developments in petrochemical processes and in the type of fossil fuel resources used have gradually led to a decrease in the volumes of mineral paraffins produced. In 2013, the National Petrochemical & Refiners Association in the USA estimated that 25% of global volumes were at risk, for three main reasons: 1) greater efficiency in catalytic cracking processes for paraffins, 2) a constantly decreasing demand for oil, and 3) the recent development of shale gas, which produces significantly fewer paraffin co-products than oil cracking. Consequently, the need to develop renewable alternatives is becoming increasingly important for sectors that are heavy users of mineral paraffins.

[0010] With regard to natural waxes of plant and animal origin, such as camauba, candelilla, and beeswax, other problems have arisen. First, candelilla and camauba waxes are obtained through processes and supply chains that are not very respectful of human rights or the environment. Very low-wage labor exposed to toxic substances has significantly discredited the resulting waxes. To such an extent that these waxes do not meet the CSR (Corporate Social Responsibility) criteria now required by many industrial sectors. Furthermore, these waxes are extracted from plants harvested from the environment in a wild and uncontrolled manner, resulting in a negative impact on biodiversity. Thus, the candelilla plant Euphorbia antisiphilityca is now registered to the CITES list of plants in danger. Finally, the production of carnauba and candelilla waxes is often affected by climatic conditions and sometimes difficult access to the resource, leading to frequent supply disruptions.

[0011] Regarding beeswax, its animal origin limits its use in certain sectors such as natural cosmetics and certified "vegan" products. Furthermore, it is a by-product of large-scale honey production and is therefore contaminated by pesticides that must be eliminated through costly purification processes.

[0012] Finally, in many applications, natural waxes cannot completely replace paraffins because they have lower melting points and do not have the same hardness.

[0013] Vaseline, also known as petrolatum, is a raw material belonging to the class of mineral oils, with a smooth to slightly pasty texture. It is a widely used ingredient in food (as an additive) and in cosmetics, particularly in balms and lipsticks, moisturizing creams, and hair care products. However, the use of vaseline is increasingly controversial and subject to strict regulations (Final Report on the Safety Assessment of Petroleum Distillate, Journal of the American College of Toxicology, Volume 5, Number 3, 1986, Statutory Instruments - Consumer Protection, The Cosmetic Products (Safety) Regulations 2008, No. 1284, pp. 1-144).

[0014] This is why, in cosmetics, numerous plant-based substitutes have been proposed, for example in US3764537, US4659573, US5976560, or WO 2007 / 107966, which consist of mixtures primarily composed of fatty esters of vegetable oils, vegetable oils, and hydrogenated vegetable oils. The semi-synthetic nature of these substitutes, as well as their multi-component composition, makes their incorporation into various types of topical formulations, makeup, and hair products difficult. Consequently, it is necessary to develop substitutes that are simpler to use and composed of a minimum number of ingredients, ideally no more than two.

[0015] Lanolin and its derivatives have long been used ingredients in cosmetics. They are used for their moisturizing properties for skin and hair (Final Report for the Safety Assessment of Acetylated Lanolin Alcohols and Related Compounds, Cosmetic Ingredient Review, https: / / www.cir-safety.org / sites / default / files / 115_buff3g_suppl.pdf). They are also lubricants, giving formulations a soft and smooth feel, and even, in some applications, an adhesive effect. Produced from sheep's wool, their animal origin significantly limits their use in cosmetics, particularly since the mad cow disease crisis and the consumer trend towards vegan and responsibly sourced products. animal welfare is a concern. Therefore, many lanolin substitutes have been proposed, for example in WO 2005 / 044203, JP 2019047841 and / or US 5,436,006. Again, these are complex mixtures of natural and semi-synthetic ingredients which make it difficult to incorporate them into different types of cosmetic formulations (makeup, skincare, haircare, etc.).

[0016] Silicones, and in particular dimethicones and their derivatives, are widely used ingredients in cosmetics (Final Report on the Safety Assessment of Dimethicone Copolyol, Journal of the American College of Toxicology, Volume 1, Number 4, 1982, Silicone Polymers in Skin Care, Anthony J. O'Lenick and Kevin A. O'Lenick, MRS Bulletin, Vol. 32, October 2007, www.mrs.org / bulletin). Among silicones, dimethicones (polydimethylsiloxanes, PDMS) are the most widely used in cosmetics, notably for their film-forming properties. Dimethicones and their derivatives form a surface film on the skin and coat the hair. From a sensory perspective, they provide shine and a silky, soft feel. Despite their remarkable properties, they are increasingly rejected by consumers because they are suspected of not being non-toxic.Consequently, the cosmetics industry is developing products labeled "silicone-free." Many different types of substitutes are also available. For example, SEPPIC offers linear and branched alkane fractions obtained by hydrocracking vegetable oils (S. Duprat-de-Paule. Augmented Bio-based Lipids for Cosmetics. OCL 2018, 25(5), 2018 pp 2-12). While partially replicating some of the sensory properties of silicones, these alkanes do not have the hair-coating power of dimethicones. Similarly, INOLEX offers plant-based alternatives to silicones under the brand name LexFeel™, which are bio-based synthetic esters (glyceryl triheptanoate, heptyl undecylenate, diheptyl succinate). These esters have the disadvantage of being easily hydrolyzed and releasing strongly odorous alcohols and fatty acids, unlike silicones which have excellent stability to hydrolysis.It is therefore necessary to develop substitutes for silicones, and in particular dimethicones, which have excellent hydrolysis stability and a strong hair-coating capacity.

[0017] In order to address the various problems associated with the use of mineral paraffins and natural waxes, substitutes have been proposed. For example, application WO 03 / 093404 claims compositions comprising hydrogenated polymerized oils. However, the production process involves chemical synthesis steps, specifically the polymerization of drying oils (soybean, linseed, safflower) and their hydrogenation at high temperature, which are energy-intensive and hazardous process steps. Furthermore, these polymerized and hydrogenated oils do not allow for the production of waxy compositions with a very high melting point. melting point, that is, above 90°C.

[0018] US patent application 8,529,924 discloses paraffin wax substitutes for candle making, consisting of hydrogenated vegetable oils. Here again, the production process involves a relatively hazardous procedure, in this case catalytic hydrogenation, and leads to compositions with limited melting points.

[0019] US application 4,842,648 claims a paraffin wax substitute consisting of glycerol monostearate and refined palm stearin. However, the maximum melting point of the composition is significantly lower than that of paraffin waxes.

[0020] US patent application 8,685,118 discloses paraffin substitutes obtained by intermolecular metathesis of unsaturated vegetable oils. The metathesis reaction involves the use of homogeneous, specific, and expensive catalysts, making the process economically unviable. Furthermore, it is known to those skilled in the art that the selectivity of metathesis reactions is difficult to control and leads to the production of complex mixtures of coupling products whose final rheological properties are difficult to determine.

[0021] Furthermore, when using inorganic pigments or organic pigments in an oil phase, the particles have a tendency to agglomerate. This is due to the incompatibility of the pigment coating with the oil phase. Agglomerates then form, which can trap air pockets. This results in viscous and non-homogeneous pastes that are difficult to incorporate into cosmetic formulations. When applied to the skin, products formulated with these pastes are difficult to spread, and the resulting color is not homogeneous.

[0022] Agglomerates are loosely bound particles which can normally be broken up using roto-stator mills or propeller mixers with the aid of a dispersing agent.

[0023] In cosmetic formulations, the main compounds used as aqueous phase dispersants are sodium polyacrylate and sodium polynaphthalene sulfonate. The main compounds used as oil phase dispersants are castor oil and its derivatives. Castor oil is a polar oil composed of more than 90% glyceryl triricinolate and ricinoleic acid, an unsaturated hydroxylated fatty acid that provides excellent steric stabilization. Polyhydroxystearic acid (PHA) is produced from hydroxystearic acid by hydrogenating ricinoleic acid and polymerizing it as a polyester. This product is a castor oil-derived dispersant widely used in cosmetic formulations.

[0024] However, ricin is classified among the potential substances that may be used for bioterrorism. It is also highly allergenic to the skin and respiratory system. This problem explains why castor oil is no longer produced in Europe but only in the countries where it is cultivated, particularly India.

[0025] Castor oil is also dangerous to extract because the seeds contain active ricin, a powerful toxin that can be fatal if ingested. Extraction also requires complete refining of the castor oil to ensure its safe use (degumming, neutralization, decolorization, and deodorization), acid hydrolysis in the presence of sulfuric acid as a catalyst to produce castor fatty acids, selective fractionation of castor fatty acids to obtain ricinoleic acid (RA), pressure hydrogenation of RA leading to hydroxystearic acid (HA), and selective polycondensation of HA to PHA (intermolecular polyesterification) to limit lactone formation resulting from intramolecular condensation of HA upon itself.

[0026] APH is therefore produced from a hazardous raw material and following a complex chemical synthesis.

[0027] Quite surprisingly, the applicant has developed a plant extract comprising a polyisoprene exhibiting excellent dispersing power for solid particles, in particular pigments and sunscreens, and not exhibiting the aforementioned disadvantages.

[0028] Furthermore, the process for preparing the plant extract according to the invention has the advantage of not having any chemical synthesis steps, being environmentally friendly, non-toxic and safe.

[0029] Application EP145621 A2 discloses the use in cosmetics of a composition comprising a polyisoprene having a molecular weight of 100,000 to 4,000,000 Da, a clay, and an organic solvent, said composition having film-forming and adhesive properties. The polyisoprene used in this application is a synthetic polyisoprene from KRATON POLYMERS.

[0030] This application does not disclose any plant extracts comprising polyisoprenes.

[0031] Application FR2962905 Al discloses a care and / or makeup composition for keratin fibers, comprising 3% by weight of isododecane, an elastomeric polymer(s) comprising at least one motif selected from isoprene, butadiene and / or butylene or said elastomeric polymer(s) having a molecular weight greater than or equal to 100,000 g / mol, and a tackifying resin.

[0032] This application refers to application EP1454621 A2 described above for the definition of polyisoprenes. The polyisoprene used is in particular a synthetic polyisoprene from the company KRATON POLYMERS.

[0033] US patent application US2008 / 0299057 Al discloses a method for preparing a solid dispersion in an organic solvent comprising the steps of combining Solid particles in powder form with a dispersing composition comprising 10 to 90% of an oil-soluble surfactant, 10 to 90% of an anhydride-based polymer, including, among a long list of potential polymers, maleinized polyisoprenes, and 0 to 50% of a liquid oily carrier. The anhydride-based polymer specified in this application has a molecular weight between 1,000 and 50,000 Da.

[0034] These applications do not disclose any plant extracts comprising polyisoprenes.

[0035] The plant extract according to the invention also has the advantage of being an alternative to paraffins, respectful of humans and the environment, non-ecotoxic and bio-accumulable, natural, renewable, vegan, low toxicity and exhibiting an excellent naturalness index.

[0036] It also has the advantage of maintaining very high stability over time of rheological, functional, safety, viscosity properties, and high resistance to hydrolysis.

[0037] Finally, it has many properties of interest for its use in cosmetics and / or therapeutics, including softening and melting temperatures particularly suited to formulation, emulsifying properties, spreading properties, film-forming properties, gelling power and a hair-coating effect.

[0038] Also, the extract according to the invention combined with one or more ingredients is an alternative to petroleum jelly, lanolin and dimethicones, the disadvantages of which have been stated above.

[0039] The plant extract according to the invention can finally be obtained from shea (Vitellaria paradoxal, more precisely from shea butter (INCI: BUTYROSPERMUM PARKII BUTTER) and in particular from the precipitate from the shea butter fractionation process, an unvalued co-product of the shea butter industry.

[0043] In one embodiment, the plant extract according to the invention is characterized in that that its unsaponifiable content is within a range of 93% to 98% (w / w) relative to the total mass of the plant extract.

[0044] For the purposes of the present invention, "unsaponifiable" means compounds that are insoluble in water but soluble in organic solvents. Unsaponifiables include, in particular, squalene, sterols, methyl sterols, triterpene alcohols, tocopherols, and / or hydrocarbons.

[0045] The determination of the unsaponifiable content may be carried out by any method conventionally known to those skilled in the art. Advantageously, it may be carried out by the standardized method NF EN ISO 18609.

[0688] In one embodiment, the process for obtaining a plant extract according to the invention is characterized in that it further comprises a step ai), after step a), in which a saponification step of said precipitate is carried out in a concentrated sodium hydroxide and / or potassium hydroxide solution.

[0689] For the purposes of the present invention, "concentrated sodium hydroxide solution" or "concentrated potassium hydroxide solution" means a sodium hydroxide or potassium hydroxide solution concentrated to at least 1% (w / w) by weight of sodium hydroxide or potassium hydroxide relative to the total weight of the sodium hydroxide or potassium hydroxide solution.

[0692] In one embodiment, the saponification step a1) is carried out in the absence of ethanol.

[0693] The absence of a treatment step with a solvent from the family of linear, branched and / or cyclic alkanes, and / or from the family of aromatic compounds has the advantage of ensuring the naturalness of the product obtained, also allows working in non-ATEX conditions and increasing the yield of unsaponifiable matter.

[0694] The absence of alcohol as a solvent in the saponification step ai) allows for working at a higher temperature, thus improving the ability to avoid vigorous agitation because the viscosity remains moderate, whereas it would tend to increase as the process progresses. Triglycerides are transformed into soaps at low temperatures.

[0695] In the presence of ethanol, the yield of the unsaponifiable fraction according to the invention is significantly altered, as the alcohol carries away a substantial portion of the unsaponifiable fraction according to the invention during washing with water. The absence of ethanol therefore also makes it possible to increase the yield of unsaponifiable content.

[0711] In one embodiment, the process for obtaining a plant extract according to the invention is characterized in that it further comprises a step a3), after step a2) as previously defined, in which the soapy phase is removed to obtain a light phase.

[0712] In one embodiment, the process for obtaining a plant extract according to the invention is characterized in that it further comprises a step c), after step b), in which the acid-treated light phase obtained in step b) is washed with demineralized water and / or with a saline solution,

[0713] In one embodiment, step c), is carried out at a temperature greater than or equal to 100°C.

[0715] In one embodiment, step c) is repeated at least twice.

[0716] In one embodiment, step c) is repeated at least four times.

[0724] For the purposes of the present invention, a process step carried out "hot" means any step carried out at a temperature above 90°C.

[0725] Carrying out the process steps at a high temperature lowers the viscosity of the reaction medium, achieving almost complete saponification of fatty acids and glycerides in a relatively short time compared to a reaction carried out below 90°C. Similarly, a high temperature prevents crystallization of the extract according to the invention, which would result not only in reduced yield but also in clogging of the installation, making it impossible to drain the reactor to recover the extract according to the invention.

[0726] In one embodiment, the process further includes a step of grinding the plant extract obtained.

The crucible is then gradually heated at a temperature ramp of 10°C / min, with the temperature range for the analysis being between 25 and 800°C.

[0791] The soap content is determined according to the following protocol:

[0792] In a 250 ml Erlenmeyer flask, 50 ml of a 3% acetone solution in water and 3 to 6 drops of bromophenol blue are introduced.

[0793] Next, 2 to 3 drops of a 0.01 M sodium hydroxide solution are added until the blue color change is obtained.

[0794] Shake and then bring back very precisely to the light green colour with a 0.01 M hydrochloric acid solution.

[0795] Add a precise mass (m) of extract, then shake vigorously and allow to settle. In the presence of soaps, the upper layer turns blue.

[0796] Titrate with 0.01 M hydrochloric acid until the indicator in the upper layer turns yellow. Note the precise volume of acid added (V). The blue or green color should not reappear after 10 minutes and after vigorous stirring and settling.

[0797] The soap content is given by the following formula:

[0798] [Math.l] I eneur en savons =---—757----—

[0799] Content expressed in mg of soaps / g of extract

[0800] M: molar mass of sodium oleate, i.e. 304 g / mol

[0801] N: molarity of the HCl solution, i.e. 0.01

[0802] V: volume of HCl in ml

[0803] m: the mass in g of extract according to the invention

[0804] The percentage of soaps is determined by the following formula:

[0805] [Math.2] % soap = 0.1 x Soap content

[0806] The determination of the molecular masses and relative contents of the polyisoprenes is carried out by multi-detection size exclusion chromatography (MD-SEC) analysis.

[0807] Molar mass measurements were performed using a Viscotek TDA SEC (Malvem Panalytical), comprising a differential refractive index detector, a viscometer, a light scattering detector, and a UV detector. Stabilized THF was used as the mobile phase at a flow rate of 1 mL / min at 35 °C.

[0808] All samples were injected at a concentration of approximately 3 mg / mL (THF solvent) after filtration through a 0.45 µm PTFE membrane (injection volume: 100 pL). Separation was performed on three Agilent C-mixed columns (SDVB, 5 µm, 300 x 7.5 mm) and one guard column. Mn and D were determined using a conventional calibration curve based on certified PS (Polymer Standards Service) standards from 470 to 270,000 g / mol. Omnisec software was used for data acquisition and analysis.

[0809] The plant extract according to example 1.2 is mainly composed of 2 families of polymers of different molecular masses and which together represent about 88% of the extract.

[0810] The dispersity of these 2 families is between 1.4 and 1.6.

[0811] In order to determine the conformation of the polyisoprenes in the extract according to Example 1.2, a carbon-13 NMR analysis was performed in deuterated chloroform (CDC13) on a Bruker Avance 400 spectrometer (13C: 100.61 MHz). The carbon-13 NMR spectra were recorded with a 10 mm SEX 13C selective probe. The spectra obtained are shown in [Fig. 1].

[0812] The relative contents of the cis-1,4 and trans 1,4 forms are 49.9 and 50.1% respectively.

[0813] The results of the different tests are presented in Table 1.

[0814] Example 2.2: Solubility of the extract according to the invention

[0815] The solubility of the extract according to Example 1.2 in ethanol, acetone and chloroform is determined according to the following procedure:

[0816] In an Erlenmeyer flask, weigh precisely 100 mg of extract, example 1.2.

[0817] Add exactly 10 ml of solvent (solvents tested: ethanol, acetone and chloroform).

[0818] Using a magnetic stirrer, stir vigorously for 30 minutes.

[0819] Filter the solution under vacuum using a Buchner filter.

[0820] Evaporate the filtrate under vacuum in the rotary evaporator (vacuum: 20 mbar, temperature: 70°C) after having previously tared the recipe flask.

[0821] After visually observing the evaporation of the solvent, maintain the recipe flask under vacuum and at temperature for 1 hour.

[0822] Accurately weigh the recipe flask (previously tare) in order to determine the mass of extract solubilized in the solvent.

[0823] The results are presented in Table 2. [Tables 2] Solvent Solubility in g / L (at 20°C) Comment Ethanol 3.6 Slightly soluble Acetone 5.1 Slightly soluble Chloroform 23.4 Partially soluble

[0824] It can be seen from the results in Table 2 that the extract according to Example 1.2 is slightly soluble in ethanol and acetone and partially soluble in chloroform.

[0825] Example 2.3: UV absorbance of the extract according to the invention.

[0826] The UV analysis of the extract according to example 1.2 is carried out on a Secoman Uviline 9400 instrument. The settings are as follows:

[0827] Wavelength scale: 190 - 400 nm.

[0828] Scan speed: slow.

[0829] Sampling interval: 0.2 s.

[0830] Scan mode: automatic.

[0835] The results are presented in Table 3. [Tables 3] Xmax (nm) Absorbance 194.3 0.604 239.9 1.438 276.8 1.732

[0836] Example 2.4: Infrared absorbance (FT-IR) of the extract according to the invention

[0837] The infrared spectrum of the extract in Example 1.2 was obtained on a Thermoscientific Thermo NICOLET IS10 FT-IR instrument equipped with a LiTA 03 detector (15700-370 cm-1). The measurement conditions were as follows: - Acquisition: 10 scans, - Resolution: 2 cm⁻¹, - Velocity: 0.2 cm.s-1.

[0838] The analysis is carried out in the solid state directly on the extract in example 1.2 and without prior preparation.

[0839] A spectrum is obtained, shown in [Fig.2], which exhibits principal bands at the following wavelengths:

[0840] 3 important bands in the range 876 to 895 cm-1

[0841] 2 prominent bands in the range 1376 to 1446 cm-1

[0842] 3 prominent bands in the interval 2850 and 2961 cm-1

[0843] We also note 4 bands in the interval 1639 to 1742 cm-1.

[0844] This spectrum is very close to that of synthetic 1,4-polyisoprene (Efficient One-Pot Synthesis of End-Functionalized trans-Stereoregular Polydiene Macromonomers. S Georges & coll, January 2019, Macromolecules, 52 (3)).

[0845] Example 2.5: Identification and relative quantification of residual esters

[0846] The identification and quantification of residual esters from extracts obtained according to example 1.2 or 1.3 is carried out by 1) extraction of the esters with diethyl ether followed by 2) analysis of the latter by gas chromatography.

[0847] A quantity of 2 g of extract obtained according to example 1.2 or 1.3 is finely ground and then introduced into a 50 mL round-bottom flask to which 20 mL of diethyl ether is subsequently added. The mixture is stirred for 20 minutes at room temperature. The mixture is then filtered through a Büchner funnel.

[0848] The diethyl ether phase is then evaporated under vacuum in a rotary evaporator until a dry extract is obtained. This extract is then silylated. To do this, the dry extract is silylated in 1 mL of pyridine and 0.5 mL of hexamethyldisilazane. The mixture is then vigorously stirred. Finally, 0.5 mL of chlorotrimethylsilane is added. After a few minutes, a white precipitate forms and is removed by filtration.

[0855] The liquid phase is then analyzed by gas chromatography under the following conditions: Column: BP5 phase (internal diameter 0.32 mm x length 30 m x film thickness 0.25 µm). Column temperature program: 60°C for 1 minute, then temperature increase with a ramp of 10°C / min until reaching 350°C.

The compositions to be tested (dispersions A, B, C, D, E, or F) are prepared by mixing all the ingredients one by one in a suitably sized glass beaker in the proportions indicated in Tables 5 and 6. The resulting mixtures are heated to 85°C using planetary stirring. Once the mixture has reached 85°C, it is allowed to cool to room temperature using planetary stirring at a speed of 700 to 1200 rpm.

[0856] Photographs of the dispersions obtained are presented in [Fig.3].

[0857] The dispersions obtained with the plant extract according to example 1.2. (dispersions C and F) and with the plant extract according to example 1.3. (dispersions B and E) are the most fluid and more homogeneous compared to the dispersions obtained without the plant extract according to example 1.2 or according to example 1.3 (dispersions A and D). The improvement in fluidity, homogeneity and hue is much greater with the plant extract according to example 1.2.

[0858] In order to quantify these results, viscosity measurements of the dispersions were carried out using a VISCOMETER MDJ-1 viscometer. The results are presented in Table 7.

[0859] Viscosity measurements of compositions B, CE and F indicate that the pigment dispersions prepared with the plant extract according to Example 1.2 (according to the invention) are significantly more fluid than the pigment dispersions prepared with the plant extract according to example 1.3, whether for titanium dioxide or red iron oxide. This macroscopic observation indicates that at the microscopic level, the dispersing power of the plant extract according to example 1.2 (according to the invention) is much greater than that of the plant extract according to example 1.3.

[0860] In order to observe microscopically the improvement in pigment dispersion by the extract according to example 1.2, the following preparations were observed by electron microscopy according to the following protocol:

[0861] The ingredients as presented in Table 8 are mixed one by one in a suitably sized glass beaker. Heat this mixture to 85°C using planetary stirring. When the mixture has reached 85°C, cool it using planetary stirring at a speed of between 700 and 1200 rpm to room temperature.

[0862] The particle size distribution graphs of red iron oxide in MYRITOL® 318 are shown in [Fig. 4] for mixture A2334 (not including the extract according to the invention) and in [Fig. 5] for mixture A2335 (including the extract according to the invention). The analysis shows that, for [Fig. 4], 89% of the particles have a size of 0.075 pm, and for [Fig. 5], 64% of the particles have a size of 0.075 pm.

[0863] The images obtained by electron microscopy are shown in [Fig.6] for mixture A2334 (not including the extract according to the invention) and in [Fig.7] for mixture A2335 (including the extract according to the invention).

[0864] Electron microscopy measurements indicate a 39% improvement in particle size distribution.

[0865] These results confirm that the addition of the extract according to example 1.2 (according to the invention) improves the dispersion of red iron oxide particles in MYRITOL® 318.

[0868] Mix all the ingredients one by one in a suitably sized glass beaker. Heat this mixture to 85°C using planetary stirring. When the mixture has reached 85°C, cool it to room temperature using planetary stirring at a speed of 700 to 1200 rpm.

[0869] In order to quantify these results, viscosity measurements of the formulations were carried out using a VISCOMETER MDJ-1 viscometer.

[0870] The viscosities of formulations comprising titanium dioxide and CETIOL® AB (C12-15 ALKYL BENZOATE) alone or in the presence of the plant extract according to Example 1.2 (according to the invention) are shown in Table 10.

[0872] The results obtained indicate that adding 10% of the plant extract according to Example 1.2 (according to the invention) to a 20% TiO2 dispersion in C12-15 ALKYL BENZOATE results in an 89% increase in average SPF, a 56% increase in average UVA protection, and an increase of over 100% in water resistance. These results indicate that the plant extract according to Example 1.2 (according to the invention), thanks to its strong ability to disperse TiO2, is a booster of SPF, UVA protection, and water resistance—properties highly sought after in the development of sunscreens.
