Description

TITLE OF THE INVENTION

ANHYDROUS EYELASH COMPOSITIONS CONTAINING SILICONE RESINS AND

PLASTICIZER

FIELD OF THE INVENTION

[0001] The present invention relates to anhydrous eyelash compositions, such as mascara compositions, comprising at least one MQ resin, at least one silicone resin comprising at least one T unit, and at least one plasticizer, preferably polybutene. The compositions have beneficial cosmetic properties including transfer-resistance, long-wear (for example, up to 36 hours), sebum-resistance, sweat-resistance, waterproof, heat and humidity proof and/or volumization of eyelashes.

The compositions also can have reduced viscosity as compared to traditional volumizing mascaras.

DISCUSSION OF THE BACKGROUND

[0002] Mascaras are in particular prepared on the basis of two types of formulations: aqueous mascaras referred to as cream mascaras, in the form of an emulsion of waxes in water, and anhydrous or low-water- content mascaras, referred to as water-resistant mascaras (referred to as "waterproof), in the form of dispersions of waxes in organic solvents.

[0003] Thickening or filling mascaras are generally known, and these mascaras can impart volume to eyelashes. This effect is generally obtained by depositing a maximum of solid substances onto the eyelashes. Generally speaking, it is through the qualitative and quantitative choice of the solid particles, in particular the waxes, that the application properties sought for such make-up compositions, such as for example their fluidity or consistency, their covering power or their thickening power (also called filling or make-up power), can be adjusted.

[0004] In addition, the aqueous mascaras mainly contain a surfactant system, for example based on triethanolamine stearate, which makes it possible to obtain a stable dispersion of particles of wax agglomerated in an aqueous phase. This system plays an important part in the obtaining of such a dispersion, in particular at the interface in the interactions between particles of wax.

[0005] Anhydrous mascaras have the disadvantages of, among other things, being dry, having poor flexibility, poor consistency and/or high viscosities that can produce lumps on the lashes.

[0006] There is thus a need to develop a cosmetic composition, in particular for making up the eyelashes, making it possible to obtain a smooth and homogeneous deposit on the eyelashes, while exhibiting a consistency that is easy to work after application, which has improved volumizing and/or long-wear properties.

DETAILED DESCRIPTION OF THE INVENTION

[0013] As used herein, the expression "at least one" means one or more and thus includes individual components as well as mixtures/combinations.

[0014] Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term “about,” meaning within 10% of the indicated number.

[0015] "Film former" or “film forming agent” as used herein means a polymer or resin that leaves a film on the substrate to which it is applied, for example, after a solvent accompanying the film former has evaporated, absorbed into and/or dissipated on the substrate.

[0016] "Transfer resistance" as used herein refers to the quality exhibited by compositions that are not readily removed by contact with another material, such as, for example, an item of clothing or the skin. Transfer resistance may be evaluated by any method known in the art for evaluating such. For example, transfer resistance of a composition may be evaluated by a modified "kiss" test or material transfer test. This test may involve application of the composition to human keratin material such as eyelashes followed by rubbing a material, for example, a sheet of paper or cotton ball, against the eyebrows after expiration of a certain amount of time following application, such as 2 minutes after application. Similarly, transfer resistance of a composition may be evaluated by the amount of product transferred from a wearer to any other substrate, such as transfer from the eyelashes of an individual to an article of clothing when putting on the clothing after the expiration of a certain amount of time following application of the composition to the eyelashes. The amount of composition transferred to the substrate (e.g., clothing, paper or cotton ball) may then be evaluated and compared. For example, a composition may be transfer resistant if a majority of the product is left on the wearer’s eyelashes. Further, the amount transferred may be compared with that transferred by other compositions, such as commercially available compositions. In a preferred embodiment of the present invention, little or no composition is transferred to the substrate from the eyelashes.

[0017] "Long wear" compositions as used herein, refers to compositions where color remains the same or substantially the same as at the time of application, as viewed by the naked eye, after an extended period of time. Long wear properties may be evaluated by any method known in the art for evaluating such properties. For example, long wear may be evaluated by a test involving the application of a composition to eyelashes and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately following application to eyelashes and these characteristics may then be re-evaluated and compared after a certain amount of time such as after 24 hours or 36 hours. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions.

[0018] “Sebum-resistance,” “sweat-resistance,” “waterproof,” heat and humidity proof, and “volumizing” properties as used herein may be evaluated by any method known in the art for evaluating such properties. For example, “sebum-resistance,” “sweat-resistance,” and “waterproof” properties may be evaluated by applying a composition to eyelashes and evaluating the color of the composition after an extended period of time and exposure to sebum, sweat and water, respectively.

For example, the color of a composition may be evaluated immediately following application to eyelashes and these characteristics may then be re-evaluated and compared after a certain amount of time such as after 20 minutes. Also for example, application to sebum, sweat and/or water can occur through various means including exposure to sauna conditions (40-45% humidity and temperatures of 50°C -56°C or pool test (humidity 56.6 - 87.1%) for a defined period of time (for example, 20 minutes). “Volumizing” properties can be evaluated through consumer testing to determine visual effect of volumization after application. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions using the same known methodologies.

[0019] “Viscosity” as used herein may be evaluated by any typical means such as, for example, using a Brookfield T: 25 C SP 93/0.3 RPM Helipath (average between 30 s & 1 min). Preferably, compositions of the present invention have a “cream” or “creamy texture,” meaning that the compositions have a viscosity of less than 1 ,500,000 cPs, preferably less than 1,300,000 cPs, and preferably less than 1,250,000 cPs, including all ranges and subranges there between such as, for example, preferably from about 400,000 cPs to 1 ,500,000 cPs, preferably from about 500,000 cPs to about 1 ,400,000 cPs, preferably from about 750,000 cPs to about 1 ,300,000 cPs and preferably from about 850,000 cPs to about 1 ,200,000 cPs, including all ranges and subranges therebetween.

[0020] “Substituted” as used herein, means comprising at least one substituent. Non-limiting examples of substituents include atoms, such as oxygen atoms and nitrogen atoms, as well as functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalky groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen containing groups, ester groups, thiol groups, sulphonate groups, thiosulphate groups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.

[0021] “Volatile”, as used herein, means having a flash point of less than about 100°C. [0022] “Non-volatile”, as used herein, means having a flash point of greater than about 100°C.

[0023] “Anhydrous” means the compositions contain less than 1% water. Preferably, the compositions of the present invention contain less than 0.5% water and most preferably no water.

[0024] “Polymer” as used herein means a compound which is made up of at least two monomers.

[0025] "Free" or "substantially free" or "devoid of" as it is used herein means that while it is preferred that no amount of the specific component be present in the composition, it is possible to have very small amounts of it in the compositions of the invention provided that these amounts do not materially affect at least one, preferably most, of the advantageous properties of the conditioning compositions of the invention. Thus, for example, "free of triethanolamine (TEA)” means that TEA is omitted from the composition (that is, 0% by weight), "substantially free of TEA" means that TEA is are present in amounts not greater than 0.5% by weight, and "devoid of TEA" means that TEA is present in amounts not greater than 0.25% by weight, based on the total weight of the composition. The same nomenclature applies for other ingredients identified throughout the application such as, for example, silicone oils ("free of silicone oils," "substantially free of silicone oils," and "devoid of silicone oils" have meanings consistent with the discussion within this paragraph).

[0026] The compositions and methods of the present invention can "comprise," "consist of" or "consist essentially of" the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful. For purposes of the compositions and methods of the present invention where the invention "consists essentially of" the identified ingredients and/or process steps, the "basic and novel property" of such compositions and/or methods is "volumizing" and/or “long-wear” properties depending upon the ingredients involved as described below. Of course, embodiments specifically directed to “consisting essentially of” one property such as “volumizing” or “long- wear” or “sebum-resistance” or “sweat-resistance” or “waterproof” or “texture” or “viscosity” or “heat and humidity proof” have as the sole basic and novel property the one identified property.

[0027] Silicone Resin Component

[0028] As used herein, the term “resin” means a crosslinked or non-crosslinked three-dimensional structure. Silicone resin nomenclature is known in the art as "MDTQ" nomenclature, whereby a silicone resin is described according to the various monomeric siloxane units which make up the polymer.

[0029] Each letter of "MDTQ" denotes a different type of unit. The letter M denotes the monofunctional unit (CH₃)₃SiOi_/2. This unit is considered to be monofunctional because the silicone atom only shares on oxygen when the unit is part of a polymer. The "M" unit can be represented by the following structure:

[0030] At least one of the methyl groups of the M unit may be replaced by another group, e.g., to give a unit with formula [R(CH₃)₂]SiOi_/2, as represented in the following structure:

[0031] wherein R is chosen from groups other than methyl groups. Non-limiting examples of such groups other than methyl groups include alkyl groups other than methyl groups, alkene groups, alkyne groups, hydroxyl groups, thiol groups, ester groups, acid groups, ether groups, wherein the groups other than methyl groups may be further substituted.

[0032] The symbol D denotes the difunctional unit (CH₃)₂Si0_2/2 wherein two oxygen atoms bonded to the silicone atom are used for binding to the rest of the polymer. The "D" unit, which is the major building block of dimethicone oils, can be represented as:

[0034] At least one of the methyl groups of the D unit may be replaced by another group, e.g., to give a unit with formula

[R(CH₃)₂]Si0_1/2.

[0035] The symbol T denotes the trifunctional unit, (CH₃)Si0_3/2 and can be represented as: [0036]

[0037] At least one of the methyl groups of the T unit may be replaced by another group, e.g., to give a unit with formula [R(CH₃)₂]SiOi_/2.

[0038] Finally, the letter Q means a tetrafunctional unit S1O4/2 in which the silicon atom is bonded to four hydrogen atoms, which are themselves bonded to the rest of the polymer.

[0039] Thus, a vast number of different silicone polymers can be manufactured. Further, it would be clear to one skilled in the art that the properties of each of the potential silicone polymers will vary depending on the type(s) of monomer(s), the type(s) of substitution(s), the size of the polymeric chain, the degree of cross linking, and size of any side chain(s).

[0040] According to the present invention, compositions comprising at least one MQ resin and at least one silicone resin comprising at least one T unit are provided. Compositions of the present invention include, but are not limited to, compositions in which the silicone resin component consists essentially of MQ resin(s) and silicone resin(s) comprising at least one T unit, as well as compositions in which the silicone resin component consists of MQ resin(s) and silicone resin(s) comprising at least one T unit.

[0041] MQ Resin [0042] Suitable MQ resins in accordance with the present invention include trimethylsiloxysilicates, which may be represented by the following formula:

[0043] [(CH₃)₃Si0]_x(Si04/2)y

[0044] wherein x and y may, for example, range from 20 to 200, preferably from 40 to 150, and preferably from 50 to 80, including all ranges and subranges therebetween.

[0045] Resin MQ, which is available from Wacker, General Electric and Dow Corning, is an example of an acceptable commercially- available trimethylsiloxysilicate. Also, trimethylsiloxysilicate (TMS) is commercially available from General Electric under the tradename SR1000 and from Wacker under the tradename TMS 803. TMS is also commercially available from Dow Chemical in a solvent, such as for example, cyclomethicone. However, according to the present invention, TMS may be used in the form of 100% active material, that is, not in a solvent.

[0046] Silicone Resin Comprising At Least One T Unit

[0047] Suitable silicone resins comprising at least one T unit in accordance with the present invention are disclosed, for example, in U.S. patent applications 2007/0166271 , 2011/0038820, 2011/0002869, and 2009/0214458, the entire contents of which are hereby incorporated by reference in their entirety.

[0048] Where the silicone resin contains at least one T unit, it may thus be, for example, a T, MT, MTQ or MDTQ resin. [0049] According to preferred embodiments, the unit composition of the silicone resin can be at least 50% T units, or at least 70% T units, or at least 80% T units, or at least 90% T units.

[0050] In the M, D and T units listed as examples above, at least one of the methyl groups may be substituted. According to preferred embodiments, the at least one silicone resin comprising at least one trifunctional unit of formula (R)Si0_3/2 is chosen from the silsesquioxanes of formula: ((R')Si0_3/2)_x, in which x ranges from 100 to 500 and R' is chosen, independently by trifunctional unit, from a hydrocarbon-based group containing from 1 to 10 carbon atoms or a hydroxyl group, on the condition that at least one R' is a hydrocarbon- based group. According to preferred embodiments, the hydrocarbon- based group containing from 1 to 10 carbon atoms is a methyl group. According to preferred embodiments, the at least one silicone resin comprising at least one trifunctional unit of formula (R)Si0_3/2 is chosen from the silsesquioxanes of the formula: ((R')Si0_3/2)_x, in which x ranges from 100 to 500 and R' is chosen, independently by unit, from CH₃, a hydrocarbon-based group containing from 2 to 10 carbon atoms, or a hydroxyl group, on the condition that at least one R' is a hydrocarbon- based group.

[0051] According to preferred embodiments, the resins may contain M, D and Q units such that at least 80 mol % or at least 90 mol %, relative to the total amount of silicones, are T units. The T resins may also contain hydroxyl and/or alkoxy groups. The resins may have a total weight of hydroxyl functions ranging from 2% to 10% and a total weight of alkoxy functions that may be up to 20%; in some embodiments, the total weight of hydroxyl functions ranges from 4% to 8% and the total weight of alkoxy functions may be up to 10%.

[0052] The resin may be chosen from silsesquioxanes that are represented by the following formula: ((CH₃)Si03_/2)_x, in which x may be up to several thousand and the CH₃ group may be replaced with an R group, as described previously in the definition of the T units. The number x of T units of the silsesquioxane may be less than or equal to 500, or it may range from 50 to 500, including all ranges and subranges therebetween. The molecular weight of the silicone resin may range from 500 to 50,000 g/mol, from 500 to 20,000 g/mol, or from 500 to 10,000 g/mol, including all ranges and subranges therebetween.

It is thought that the polymer is in a "cage" and "ladder" configuration as represented in the figures below. The average molecular weight of the units in "cage" configuration has been calculated as 536 g/mol. The majority of the polymer is in the "ladder" configuration with ethoxy groups at the ends. These ethoxy groups represent 4.5% by mass of the polymer. As these end groups can react with water, a small and variable amount of SiOH groups may also be present; and
