Abstract
Description
Title of the invention: Aqueous composition comprising a fatty acid monoester, a neutralized anionic surfactant, a liquid polyester derived from a diol dimer and an unsaturated fatty acid dimer, a latex and a polyol Technical field
[0001] The present invention relates to the field of care and / or makeup of keratin materials, and aims to propose compositions more particularly dedicated to makeup of eyelashes or eyebrows.
[0002] Generally speaking, compositions dedicated to the makeup of keratin fibers, for example eyelashes, aim to densify the thickness and visual perception of the eyelashes and ultimately the look. These mascaras are described as aqueous or cream mascaras, when they are formulated in aqueous base and anhydrous mascaras when they are formulated in the state of dispersion in an organic solvent medium.
[0003] A wide variety of cosmetic effects can be achieved by applying mascara to keratin fibers, particularly eyelashes, such as, for example, a volumizing, lengthening, thickening, and more particularly a loading makeup effect.
[0004] These effects are essentially adjusted through the quantity and nature of the particles and particularly those of the waxes present in the mascaras. Generally speaking, mascaras in fact have a significant quantity of wax(es) and in particular from 10 to 35% by weight of waxes, more generally from 15 to 30% by weight, relative to their total weight.
[0005] For obvious reasons, the improvement of mascara textures which determine the manifestation of one or more makeup effects is a constant concern of the cosmetic formulator.
[0006] Furthermore, it is expected that the specific effects attached to a particular formulation, for example charging and also providing excellent separation of the made-up eyelashes, are reproduced almost identically by all the manufacturing batches of the same formulation.
[0007] Satisfying these expectations and / or objectives therefore requires being able to precisely adjust the texture of a mascara and to reproduce it as faithfully as possible with batches not necessarily manufactured at the same time but identical in terms of ingredients and therefore having to provide makeup effects which are in theory also identical.
[0008] In addition, the consumer expects a mascara with lasting performance, that is to say a mascara that resists friction (absence of grains again called “flakes”). Prior art
[0009] However, as stated above, the mascaras currently available are, for the most part, formulated with a significant amount of waxes. However, as detailed in the document Ullmann's Encyclopedia of Industrial Chemistry 2015, Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim 10.1002 / 14356007.a28.pub2 most waxes do not consist of a single chemical compound but are rather complex mixtures. They can be mixtures of oligomers and / or polymers which, in many cases, also have varying molar masses, molar mass distributions and degrees of branching. Thus, a polar wax is classically formed from a mixture of alkanes, fatty alcohols and fatty esters whose fatty chain length varies according to the melting point.
[0010] It is therefore very difficult for manufacturers of these waxes to guarantee a strictly identical composition for all manufacturing batches. More specifically, there may be, between several manufacturing batches of the same wax, variability in the chemical nature of some of its constituent compounds. Similarly, the proportionality of some of its constituent compounds is also likely to vary between manufacturing batches.
[0011] For obvious reasons, these variabilities have a significant impact on the properties of the wax and therefore on those of the mascara incorporating this wax in significant quantity. Thus, two mascara formulations of identical composition and therefore produced from the same conventional wax and in the same quantity, may nevertheless diverge in terms of rheological properties and therefore texture and mechanical properties of the deposition of the product on the keratin fibers such as resistance to crumbling (presence of grains also called "flakes"), if they have been manufactured from two separate manufacturing batches of this wax.
[0012] Consequently, the use of conventional waxes, in particular in significant quantities, in mascara compositions, does not make it possible to guarantee to users the reproduction of the rheological properties and the mechanical properties of the deposit of the product on the keratin fibers, such as the resistance to crumbling, which are finely adjusted and totally identical on all the mascara specimens of the same composition.
[0013] In patent applications FR3080034, EP3781118, EP3897859, EP3897558, EP3897519, aqueous compositions have been proposed, in particular mascaras comprising at least one fatty acid monoester such as behenyl behenate, at least one fatty acid having from 14 carbon atoms to less than 20 carbon atoms, at least one base capable of at least partially neutralizing said fatty acid, at least one base capable of at least partially neutralizing said fatty acid, and pigments, in particular iron oxides. However, these compositions are not fully satisfactory in terms of the stability of the evolution of the consistency over time, in particular over several days and according to temperature variations.
[0014] Patent FR3090334 discloses aqueous mascaras comprising behenyl behenate, a fatty acid, a neutralizing base, a semi-crystalline polymer, a fatty alcohol and a non-volatile hydrocarbon oil.
[0015] Water-based mascaras are known on the market - the commercial product Be Bold Colar Mascara (Mintel ID 5676593) containing behenyl behenate, neutralized stearic acid, waxes, black iron oxides; - Avon Super Drama Volume and Lengthening Waterproof Mascara commercial product (Mintel ID 20600879) containing behenyl behenate, neutralized stearic acid, waxes, black iron oxides; - the commercial product Stunning Extra Lush Mascara by Ying Te LI Cosmetics (Mintel ID 8372591) containing behenyl behenate, Potassium Cetyl Phosphate neutralized by a base, waxes, black iron oxides, vinylpyr-rolidone / eico sene copolymer.
[0016] During its research, the applicant found that these compositions were not fully satisfactory in terms of the mechanical properties of the deposition of the product on keratin fibers, in particular resistance to crumbling.
[0017] Thus, one of the objectives of the present invention is to access mascara compositions whose mechanical properties of the deposition of the product on the keratin fibers such as the resistance to crumbling are improved, finely adjustable and reproducible.
[0018] Another aim of the present invention is to propose a mascara architecture developed from a predominant proportion by weight of single-component ingredients. The predominant use of single-component ingredients advantageously makes it possible to overcome the risk of variability in composition that may exist between several manufacturing batches of a multi-component ingredient and therefore its impact on the final properties of the mascara.
[0019] Another aim of the present invention is to propose a mascara architecture making it possible to significantly reduce or even eliminate the use of waxes but nevertheless remaining very satisfactory in terms of makeup effect.
[0020] The inventors, during their research, unexpectedly discovered that the objectives as defined above were achieved by using a composition comprising, in particular in a physiologically acceptable medium: (1) at least one linear fatty acid monoester of the following formula (I): [Chem 1] Ri-O-Ra (I) in which R 1 and R 2 are linear and saturated and have, independently of each other, a number of carbon atoms greater than or equal to 20, with R 1 representing an acyl radical, and R 2 representing an alkyl radical, and (2) at least one anionic surfactant, and (3) at least one base capable of partially or totally neutralizing said anionic surfactant, and (4) at least one liquid polyester (4) obtained from a) at least one alcohol dimer (diol dimer), preferably saturated, the alcohol of which is C16-C32, preferably C16-C22 and b) at least one unsaturated fatty acid dimer; the fatty acid comprising from 16 to 22 carbon atoms; and (5) water; and (6) at least one film-forming polymer in the form of solid particles suspended in the aqueous phase; and (7) at least one water-soluble liquid polyol.
[0021] Unexpectedly, the inventors have in fact found that the formulation comprising at least one linear fatty acid monoester (1), at least one anionic surfactant (2) in a form partially or totally neutralized by a base (3), at least one liquid polyester (4) obtained from an unsaturated fatty acid dimer (4), water (5), at least one film-forming polymer (6) in the form of solid particles suspended in the aqueous phase and at least one water-soluble liquid polyol (7) made it possible to produce, after application to keratin materials such as eyelashes, a deposit having good resistance to crumbling.
[0022] In addition, the consistency and mechanical properties of the deposition of the formulation on the keratin fibers can be finely adjusted and guaranteed in terms of reproducibility.
[0023] As will be seen from the following, these new compositions are advantageous in several respects.
[0024] First of all, the compounds (1) to (7) required according to the invention are as an individualized compound, single-component or having a well-defined number of components as opposed to the majority of conventional waxes which are often multi-component or even with an indefinite number of compounds like natural waxes and certain synthetic waxes.
[0025] These two specificities are particularly interesting because they make it possible to avoid a risk of variability with regard to their respective compositions.
[0026] As is clear from the examples below, the compositions in accordance with the invention and based on the use of compounds (1) as texturizing agent prove to be very satisfactory in terms of makeup effects.
[0027] Thus, compositions according to the invention can have a creamy texture which proves to be finely adjustable thanks to the implementation of the combination required according to the invention.
[0028] Obtaining these properties is conditioned by the use of compounds (1) to (7) and advantageously therefore does not require the additional presence of waxes, particularly in significant quantities.
[0029] Thus, the compositions according to the invention advantageously comprise less than 5% of waxes as defined below.
[0030] Waxes are understood to mean lipophilic compounds, solid at room temperature (25°C) and at atmospheric pressure (760 mm Hg), with a reversible solid / liquid state change, having a melting point greater than or equal to 40°C and up to 120°C.
[0031] For the purposes of the invention, the waxes concerned by this limitation in quantity mentioned above are distinct from those likely to be represented by the monoester component of fatty acid(s) (1) required according to the invention and additives of the fatty alcohol type.
[0032] This discovery is the basis of the invention. Objects of the invention
[0033] Thus, according to one of its aspects, the present invention relates to a composition comprising, in particular in a physiologically acceptable medium: (1) at least one linear fatty acid monoester of the following formula (I): [Chem 1] Rs-O-Ib (I) in which Ri and R2 are linear and saturated and have, independently of each other, a number of carbon atoms greater than or equal to 20, with Ri representing an acyl radical, and R2 representing an alkyl radical, and (2) at least one anionic surfactant, and (3) at least one base capable of partially or totally neutralizing said anionic surfactant, and (4) at least one liquid polyester (4) obtained from a) at least one alcohol dimer (diol dimer), preferably saturated, the alcohol of which is C16-C32, preferably C16-C22 and b) at least one unsaturated fatty acid dimer; the fatty acid comprising from 16 to 22 carbon atoms; and (5) water; and (6) at least one film-forming polymer in the form of solid particles suspended in the aqueous phase; and (7) at least one water-soluble liquid polyol.

In such a case, it is preferred to use a mixture in which the content of this dimer diacid is greater than 70%, more particularly greater than 90% by weight, or even more preferably greater than 95% by weight; the remainder of the mixture may be trimers and / or monomers of unsaturated fatty acids.

[0244] According to a particular form, a composition according to the invention may further comprise a wax (14).
[0245] However, with regard to the objectives of the present invention, the compositions according to the invention preferably comprise a reduced quantity of wax and in particular less than 5% by weight, or even less than 3% by weight of waxes, relative to their weight. total.
[0246] As specified in the preamble, within the meaning of the invention, waxes are understood to mean lipophilic compounds, solid at room temperature (25°C) and at atmospheric pressure (760 mm Hg), with a reversible solid / liquid state change, having a melting point greater than or equal to 40°C and up to 120°C.
[0247] It is recalled that within the meaning of the invention, the waxes (14) concerned by the aforementioned limitation in quantity are distinct from those likely to be represented by the linear fatty acid monoester component (1) according to the invention and the additional fatty alcohol components (9) as defined below.
[0248] Waxes formed from complex mixtures and described in particular in the document Ullmann's Encyclopedia of Industrial Chemistry 2015, Wiley-VCH Verlag GmbH & Co. KGaA are more particularly affected by this limitation.
[0249] Such waxes can be natural but also synthetic.
[0250] By natural wax is meant any wax pre-existing in nature or capable of being transformed, extracted or purified from natural compounds existing in nature.
[0251] Among the natural waxes, we can notably cite the so-called fossil waxes including those of petroleum origin such as ozocerite, pyropissite, macrocrystalline waxes also called paraffins - including crude waxes or slack wax, slack wax raffinates, deoiled slack wax, soft waxes, semi-refined waxes, filtered waxes, refined waxes - and microcrystalline waxes called microwaxes including slack wax from "bright stock". Fossil waxes still contain lignite also called montan wax, or peat wax.
[0252] As natural waxes other than fossil waxes, we can cite animal and vegetable waxes.
[0253] Examples of vegetable waxes include carnauba wax, candelilla wax, ouricuri wax, sugarcane wax, jojoba wax, Trithrinax campestris wax, raffia wax, alfalfa wax, wax extracted from Douglas fir, sisal wax, flax wax, cotton wax, Batavia dammar wax, cereal wax, tea wax, coffee wax, rice wax, palm tree wax, Japanese wax, mixtures thereof and derivatives thereof.
[0254] Examples of animal waxes include beeswax, Ghedda wax, shellac, Chinese wax, lanolin also known as wool wax, their mixtures and their derivatives.
[0255] These waxes (13) are generally multi-component. For example, natural beeswax is composed of approximately 70% esters, the majority of which are monoesters (of fatty acid and fatty alcohol), but also hydroxy-esters, di- and triesters and sterol esters, as well as long-chain linear hydrocarbons, free acids and free alcohols. For obvious reasons, the weight proportion of their ingredients and their degree of purity are difficult to guarantee from one manufacturing batch to another.
[0256] By synthetic wax is meant waxes whose synthesis requires one or more chemical reactions carried out by man.
[0257] Among synthetic waxes, a distinction can be made between semi-synthetic waxes and fully synthetic waxes. Synthetic waxes can be waxes obtained by a Fischer-Tropsch process, consisting for example of paraffins with a number of carbon atoms ranging from 20 to 50 or polyolefin waxes, for example homo- or copolymers of ethylene, propene or butene, or even longer chain α-olefins. The latter can be obtained by thermomechanical degradation of plastic polyethylene, by the Ziegler process, by high-pressure processes, or even via processes catalyzed by metallocene species. These waxes can be crystallizable, partially crystallizable or amorphous.The above-mentioned synthetic waxes are generally apolar and can be chemically treated to obtain polar waxes, for example by one or more of the following reactions: oxidation in air, grafting, esterification, neutralization by metallic soaps, amidation, direct copolymerizations or addition reactions.
[0258] Here again, their composition can consist of a mixture of ingredients because the fatty chain lengths are not well defined, thus forming a mixture of compounds of different fatty chain lengths and for which it is difficult for manufacturers to guarantee perfect reproducibility from one manufacturing batch to another.
[0259] Consequently, the compositions according to the invention advantageously comprise less than 5% by weight, preferably less than 3% by weight of wax(es) (14), in particular natural or synthetic multi-component wax(es) relative to the total weight of the composition.
[0260] For the purposes of the invention, a multi-component wax designates a wax consisting of a mixture of several ingredients, either as it exists naturally like natural waxes, or as it is formed during the industrial synthesis process of these materials.
[0261] In a particularly preferred embodiment of the invention, the composition is free of these waxes (14), in particular multi-component natural or synthetic wax.
[0262] As specified above, the preferred texturizing compounds according to the invention are, by contrast and advantageously, single-component, synthetic compounds, and therefore available in a form purified to more than 99%, like the compound (1) required according to the invention. h) Cosmetic active ingredients (15)
[0263] As cosmetic active ingredients which can be used in the compositions according to the invention, we can cite in particular antioxidants, preservatives, perfumes, neutralizers, cosmetic active ingredients such as for example emollients, vitamins and filters, in particular sunscreens, and their mixtures.
[0264] These additives (15) may be present in the composition in a content ranging from 0.01 to 15.0%, of the total weight of the composition.
[0265] Of course, those skilled in the art will take care to choose any additional additives and / or their quantity in such a way that the advantageous properties of the composition according to the invention are not, or not substantially, altered by the envisaged addition. (i) Coloring matter (16)
[0266] A composition according to the invention, and in particular those dedicated to makeup, generally comprises at least one coloring material (16) such as powdery materials, liposoluble dyes, water-soluble dyes.
[0267] The powdery coloring materials (16) can be chosen from pigments and pearlescent agents.
[0268] The pigments may be white or colored, mineral and / or organic, coated or not. Among the mineral pigments, mention may be made of titanium dioxide, optionally surface-treated, zirconium, zinc or cerium oxides, as well as iron or chromium oxides, manganese violet, ultramarine blue, chromium hydrate and ferric blue. Among the organic pigments, mention may be made of carbon black, D & C type pigments, and lakes based on cochineal carmine, barium, strontium, calcium, aluminum.
[0269] The nacres can be chosen from white nacreous pigments such as mica coated with titanium or bismuth oxychloride, colored nacreous pigments such as titanium mica with iron oxides, titanium mica with in particular ferric blue or chromium oxide, titanium mica with an organic pigment of the aforementioned type as well as nacreous pigments based on bismuth oxychloride.
[0270] For the purposes of the invention, the term "water-soluble coloring matter" means any generally organic, natural or synthetic compound, soluble in an aqueous phase or water-miscible solvents and capable of coloring.
[0271] As water-soluble dyes suitable for the invention, mention may in particular be made of synthetic or natural water-soluble dyes such as, for example, FDC Red 4, D&C Red 6, D&C Red 22, D&C Red 28, D&C Red 30, D&C Red 33, D&C Red 40, D&C Orange 4, D&C Yellow 5, D&C Yellow 6, D&C Yellow 8, FDC Green 3, D&C Green 5, betanin (beetroot), carmine, copper chlorophyline, methylene blue, anthocyanins (enocyanin, black carrot, hibiscus, elderberry), caramel, riboflavin.
[0272] Preferably, the composition according to the invention comprises a coloring material (16) powdery, preferably of the pigment type, in particular metal oxides, in particular titanium dioxides, iron oxides and their mixtures; and more preferably iron oxides, and more particularly black iron oxides (CI 77499).
[0273] Preferably, said coloring matter (16) is present in the composition in a content ranging from 2.0 to 25.0% by weight, preferably from 3.0% to 20.0% by weight, more particularly from 4.0 to 15.0% by weight relative to the total weight of the composition. Physical characteristics a) Dry extract
[0274] The composition according to the invention advantageously comprises a dry extract content of at least 25.0% by weight, and preferably at least 30.0% by weight relative to the total weight of the composition, or even from 30.0 to 60.0% by weight, relative to the total weight of the composition.
[0275] For the purposes of the present invention, “dry extract content” means the content of non-volatile matter.
[0276] The quantity of dry extract (abbreviated ES) of a composition according to the invention is measured using a commercial halogen desiccator “HALOGEN MOISTURE ANALYZER HR 73®” from Mettler TOLEDO. The measurement is based on the weight loss of a sample dried by halogen heating and therefore represents the percentage of residual matter once the water and volatile matter have evaporated.
[0277] This technique is fully described in the device documentation provided by Mettler TOLEDO®.
[0278] The measurement protocol is as follows:
[0279] Approximately 2 g of the composition, hereinafter the sample, are spread on a metal dish which is introduced into the halogen desiccator mentioned above. The sample is then subjected to a temperature of 105°C until a constant weight is obtained. The Wet Mass of the sample, corresponding to its initial mass, and the Dry Mass of the sample, corresponding to its mass after halogen heating, are measured using a precision balance. The experimental error related to the measurement is of the order of plus or minus 2%. The Dry Extract content is calculated as follows: [Math 1] Dry Extract Content (expressed in % by weight) = 100 x \ rrj Wet Mass Consistency
[0280] Preferably, a composition according to the invention has at 25°C a consistency characterized by a hardness > 20g, more preferably, a hardness ranging from 20 to 200 g, even more preferably 30 to 150 g.
[0281] The consistency of mascaras is measured according to the following protocol:
[0282] The measuring device is a TA-XT-Plus® sold by the company STAPLES MICRO SYSTEM, equipped with a 5 kilogram force measuring cell and a 12.7 mm (1 / 2 inch) diameter cylindrical Delrin mobile. The mascara is thermostatically controlled at 20°C. Then, it is placed in excess in a container with a diameter of 60 mm and a depth of 22 mm using a metal spatula. The product is spread to avoid any air pockets but without grinding it so as not to break it up. The container is then leveled with a spatula so as to have the most even surface possible. The container is then covered with a watch glass so as to limit the evaporation of solvents present in the formula for about ten minutes. The options chosen for this measuring method are as follows: Test mode: Compression measurement Trigger force: 2.0 g Pre-speed: 0.5 mm / sec Test speed: 0.5 mm / sec Temperature: 20 °C + / - 1 °C Penetration distance: 5 mm
[0283] Three successive measurements are taken at points separated by at least 12 mm, at least 10 mm from the edge of the container. The container is held during the measurement. The value retained is the average of the maxima obtained at each measurement.
[0284] Such a consistency is particularly advantageous since it is best suited to the mascara application device.
[0285] The composition can be manufactured by known methods, generally used in the cosmetic field.
[0286] The composition used according to the invention may be a makeup composition, a makeup base, in particular keratin fibers, or base coat, a composition to be applied over makeup, also called a top coat, or even a composition for treating keratin fibers.
[0287] More specifically, the composition according to the invention is in the form of a product for the eyelashes such as a mascara, a product for the eyebrows or a product for the eye contour such as an eyeliner, and more particularly a mascara.
[0288] Such compositions are in particular prepared according to the general knowledge of those skilled in the art.
[0289] Packaging and application assembly or kit
[0290] The present invention also relates to a set or kit for packaging and applying a cosmetic composition for coating keratin fibers. including: - a packaging device comprising said cosmetic composition for coating keratin fibers as previously described, - an applicator of said composition.
[0291] Said applicator may be integral with a gripping member forming a cover for said packaging device. In other words, said applicator may be mounted in a removable position on said device between a closed position and a position clear of a dispensing opening of the packaging device for said composition.
[0292] A keratin fiber coating assembly suitable for the invention may comprise an applicator configured to apply said cosmetic composition for coating keratin fibers, and where appropriate a packaging device suitable for receiving said composition. Applicator
[0293] The applicator comprises means for smoothing and / or separating the kera fibers tinic, such as eyelashes or eyebrows, particularly in the form of teeth, hairs, spikes or other reliefs.
[0294] The applicator is arranged to apply the composition to the eyelashes or eyebrows, and may include, for example, a brush or a comb.
[0295] The applicator can still be used for finishing the makeup, on an area eyelashes or eyebrows made up or loaded with composition.
[0296] The brush may have a twisted core and bristles caught between the turns of the core, or be made in another way.
[0297] The comb is for example made from a single piece by molding plastic material.
[0298] In some embodiments, the application element is mounted at the end of a rod, which may be flexible, which may contribute to improving comfort during application. Packaging device
[0299] The packaging device comprises a container intended to house the composition for coating the keratin fibers. This composition can then be taken from the container by immersing the applicator therein.
[0300] This applicator may be integral with a closure element of the container. This closure element may form a gripping member for the applicator. This gripping member may form a cover to be removably mounted on said container by any suitable means such as screwing, snap-fastening, fitting or other. Such a container may therefore reversibly house said applicator.
[0301] This container may optionally be equipped with a wringer suitable for removing excess product taken up by the applicator.
[0302] A method of applying the composition according to the invention to the eyelashes or eyebrows may also comprise the following steps: - form a deposit of the cosmetic composition on the eyelashes or eyebrows, - leave the deposit on the eyelashes or eyebrows, as the deposit may dry.
[0303] It should be noted that according to another embodiment the applicator can form a product container. In such a case a container can for example be provided in the gripping member and an internal channel can internally connect this gripping member to the raised application elements.
[0304] Finally, it should be noted that the packaging and application assembly may be presented in the form of a kit, the applicator and the packaging device being able to be housed separately in the same packaging article.
[0305] The expressions “between ... and ...” and “ranging from ... to ...” must be understood inclusively, unless otherwise specified.
[0306] In the description and the examples, unless otherwise indicated, the percentages are percentages by weight.

[0310] The compositions were prepared in a MAXILAB OLSA® double-jacketed tank as follows (on 3 kg). At room temperature (25°C), all the ingredients except the Acrylates Copolymer were introduced into the tank. The mixture was heated to around 90°C with stirring. Emulsification was carried out for 15 minutes with turbine / blade / scraper stirring (speed 3000 / 30 / 42 rpm). The juice was gradually cooled up to 60°C with paddle / scraper stirring (speed = 30 / 42 rpm) at a rate of 2°C / min. Then, the acrylate copolymer was added and cooled to 35°C with paddle / scraper stirring (speed = 30 / 42 rpm) at a rate of 2°C / min, gradually deaerating the formula using a vacuum before draining at 35°C.
[0311] After packaging the formulas in a mascara applicator, they were evaluated by a friction resistance test carried out according to the protocol described below.
[0312] The formulas were deposited on false eyelashes (hair sample) by 3 times ten strokes spaced by 2 minutes of drying. The test pieces were then left to dry for 1 hour on a plate thermostatically controlled at 33°C. 30 strokes were applied to the false eyelashes using the Lancôme Kéracil® mascara brush over a white sheet. The quantity of residue (Flakes) deposited on the sheet was evaluated using an abacus defining a score from 0 to 6 (0 no residue, 6 a lot of residue). Note that a significant difference is observable when the difference is greater than or equal to 1. The results obtained are shown in the table below.

[0314] The results showed that example 1 according to the invention containing the liquid polyester DIMER DILINOLEYL DIMER DILINOLEATE associated with the polyol gives better resistance to friction compared to the counter-examples 1a, 1b, 1c and 1d outside the invention.
