Description

Technical Field

[0001] This invention relates to compositions for use as skincare and / or cosmetic keratin materials. More particularly, this invention relates to anhydrous compositions for use as skincare and / or cosmetic keratin materials. This invention also relates to cosmetic methods using skincare and / or cosmetic keratin materials. Background Technology

[0002] The ongoing goal is to develop formulations for cosmetic and / or skin care and / or lip care that are satisfactory in terms of application, comfort (especially non-greasy), good coverage, and cosmetic effect.

[0003] Lipstick has become a necessity and is considered by users as the overwhelming primary method of applying care and / or makeup to their lips. Lipstick can alter a user's facial features. For example, it can make narrow lips appear wider and wide lips appear narrower. In addition to changing the shape of the lips, lipstick can also be made in a wide variety of colors and shades to enhance the desired effect or express the wearer's mood.

[0004] However, some lipsticks are not easy to apply, and the resulting matte finish is still insufficient.

[0005] In the case of cosmetic lips, compositions in fluid form commonly referred to as lip glosses for cosmetic purposes on the skin or lips are also known. These compositions typically lack wax and generally contain at least one non-volatile oil with a molecular weight greater than 600 g / mol.

[0006] However, the deposits produced by such liquid compositions are often relatively glossy and / or greasy on the lips, which is a source of user discomfort.

[0007] At the same time, some cosmetic products using keratin materials for care and / or makeup do not provide good coverage, which is undesirable.

[0008] Therefore, there remains a demand for compositions for use in the care and / or cosmetic keratin materials (especially for lips) that are easy to apply and provide a matte finish and a lightweight feel. Invention Overview

[0010] Therefore, one object of the present invention is to develop compositions for use in the care and / or cosmetic application of keratin materials (especially for the lips) that are easy to apply and capable of providing a matte finish and a lightweight feel.

[0011] Another object of the present invention is to provide a cosmetic method for caring for and / or applying keratin materials (e.g., skin and lips, especially lips) that will produce a matte deposit with a light feel on the keratin material.

[0012] Therefore, according to a first aspect, the present invention provides an anhydrous composition for use as a care and / or cosmetic keratin material, which is a liquid and comprises:

[0013] a) At least one organopolysiloxane elastomer powder coated with silicone resin;

[0014] b) at least one organopolysiloxane elastomer transported in the first oil;

[0015] c) At least two fillers, comprising polymethylsilsesquioxane and calcium aluminum borosilicate; and

[0016] d) At least one second oil, which is a volatile hydrocarbon oil.

[0017] The composition does not contain wax and contains more than 15% by weight of filler relative to the total weight of the composition.

[0018] According to a second aspect, the present invention provides a cosmetic method for caring for and / or applying keratin materials, comprising applying an anhydrous composition as described above to the keratin material.

[0019] It has been found that the anhydrous composition according to the invention is easy to apply and can provide a matte finish and a light feel.

[0040] silicone resin coated organopolysiloxane elastomer powder

[0041] According to a first aspect of the invention, the anhydrous composition comprises at least one organopolysiloxane elastomer powder coated with a silicone resin (especially a sesquioxane resin), such as that described in, for example, patent US5,538,793 (the contents of which are incorporated herein by reference).

[0042] These elastomer powders are sold by Shin-Etsu under the names KSP-100, KSP-101, KSP-102, KSP-103, KSP-104 and KSP-105, and have the INCI name: Vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosslinked polymer.

[0043] Preferably, the silicone resin-coated organopolysiloxane elastomer powder is a compound with the INCI name of vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane crosslinked polymer.

[0044] Advantageously, the amount of silicone resin-coated organopolysiloxane elastomer powder in the composition ranges from 0.5% to 10% by weight, preferably from 1% to 8% by weight, and more preferably from 2% to 5% by weight, relative to the total weight of the composition of the present invention.

[0045] Organopolysiloxane elastomer transported in the first oil

[0046] According to a first aspect of the invention, the anhydrous composition comprises at least one organopolysiloxane elastomer (also known as a silicone elastomer) delivered in a first oil, particularly in the form of an organopolysiloxane elastomer gel.

[0047] Preferably, the first oil is a silicone oil and / or a hydrocarbon oil, which is preferably non-volatile.

[0048] Preferably, the composition comprises at least one organopolysiloxane elastomer delivered in at least one non-volatile silicone oil of the INCI name polydimethylsiloxane.

[0049] The terms "organopolysiloxane elastomer" or "silicone elastomer" refer to soft, deformable organopolysiloxanes that possess viscoelastic properties and, in particular, the consistency of a sponge or soft sphere. Their elastic modulus allows the material to withstand deformation and provides limited stretching and contraction. The material is able to return to its original shape after being stretched.

[0050] More particularly, it is a cross-linked silicone elastomer.

[0051] Silicone elastomer particles are delivered in the form of a gel, which is formed from an elastomer organopolysiloxane contained in at least one hydrocarbon oil and / or a silicone oil.

[0052] In these gels, the organopolysiloxane particles are typically non-spherical.

[0053] Non-emulsified organopolysiloxane elastomers

[0054] Therefore, organopolysiloxane elastomers can be obtained by: crosslinking addition reaction of a diorganopolysiloxane containing at least one silicon-bonded hydrogen with a diorganopolysiloxane containing an olefinically unsaturated group bonded to silicon, especially in the presence of a platinum catalyst; or dehydrogenation crosslinking condensation reaction between a diorganopolysiloxane containing a hydroxyl-terminated group and a diorganopolysiloxane containing at least one silicon-bonded hydrogen, especially in the presence of organotin; or crosslinking condensation reaction of a diorganopolysiloxane containing a hydroxyl-terminated group with a hydrolyzable organopolysiloxane; or thermal crosslinking of organopolysiloxanes, especially in the presence of an organic peroxide catalyst; or crosslinking of organopolysiloxanes via high-energy radiation (e.g., gamma rays, ultraviolet rays, or electron beams).

[0055] Preferably, the organopolysiloxane elastomer is obtained by a crosslinking addition reaction of (A) a diorganopolysiloxane containing at least two hydrogens each bonded to silicon and (B) a diorganopolysiloxane containing at least two olefinic unsaturated groups bonded to silicon, especially in the presence of (C) a platinum catalyst.

[0056] In particular, organopolysiloxane elastomers can be obtained by reacting dimethyl polysiloxane containing dimethylvinylsiloxy end groups with methylhydropolysiloxane containing trimethylsiloxy end groups in the presence of a platinum catalyst.

[0057] Compound (A) is the basic reactant for forming organopolysiloxane elastomers and is crosslinked via an addition reaction of compound (A) and compound (B) in the presence of catalyst (C).

[0058] Compound (A) is particularly an organopolysiloxane containing at least two hydrogen atoms bonded to different silicon atoms in each molecule.

[0059] Compound (A) can have any molecular structure, especially linear or branched chain structures or cyclic structures.

[0060] Compound (A) can have a viscosity ranging from 1 to 50,000 centipoise at 25°C, which is particularly convenient for miscibility with compound (B).

[0061] The organic group bonded to the silicon atom in compound (A) can be an alkyl group, such as methyl, ethyl, propyl, butyl, octyl; a substituted alkyl group, such as 2-phenylethyl, 2-phenylpropyl or 3,3,3-trifluoropropyl; an aryl group, such as phenyl, tolyl, xylyl; a substituted aryl group, such as phenethyl; and a substituted monovalent hydrocarbon group, such as an epoxy group, a carboxylic acid ester group or a mercapto group.

[0062] Therefore, compound (A) can be selected from methylhydropolysiloxanes containing trimethylsiloxy groups, dimethylsiloxane-methylhydrosiloxane copolymers containing trimethylsiloxy groups, and dimethylsiloxane-methylhydrosiloxane cyclic copolymers.

[0063] Compound (B) is advantageously a diorganopolysiloxane containing at least two lower alkenyl groups (e.g., C2-C4); these lower alkenyl groups can be selected from vinyl, allyl, and propenyl groups. While these lower alkenyl groups can be located at any position within the organopolysiloxane molecule, they are preferably located at the ends of the molecule. The organopolysiloxane (B) can have branched, linear, cyclic, or network structures, but a linear chain structure is preferred. Compound (B) can have viscosities ranging from liquid to colloidal. Preferably, compound (B) has a viscosity of at least 100 centistokes at 25°C.

[0064] In addition to the alkenyl groups mentioned above, other organic groups bonded to silicon atoms in compound (B) may be alkyl groups, such as methyl, ethyl, propyl, butyl, or octyl; substituted alkyl groups, such as 2-phenylethyl, 2-phenylpropyl, or 3,3,3-trifluoropropyl; aryl groups, such as phenyl, tolyl, or xylyl; substituted aryl groups, such as phenethyl; and substituted monovalent hydrocarbon groups, such as epoxy groups, carboxylic acid ester groups, or mercapto groups.

[0066] In particular, organopolysiloxane elastomers can be obtained by reacting dimethyl polysiloxane containing dimethylvinylsiloxy end groups with methylhydropolysiloxane containing trimethylsiloxy end groups in the presence of a platinum catalyst.

[0067] According to another alternative form, compound (B) can be an unsaturated hydrocarbon compound containing at least two lower alkenyl groups (e.g., C2-C4); these lower alkenyl groups can be selected from vinyl, allyl, and propenyl groups. Although these lower alkenyl groups can be located at any position in the molecule, they are preferably located at the end. Hexadiene, especially 1,5-hexadiene, can be mentioned by way of example.

[0068] Advantageously, the sum of the number of ethylenic groups per molecule of compound (B) and the number of hydrogen atoms bonded to silicon per molecule of compound (A) is at least 5.

[0069] Advantageously, the amount of compound (A) added is such that the molecular ratio between the total amount of hydrogen atoms bonded to silicon atoms in compound (A) and the total amount of all olefinic unsaturated groups in compound (B) is in the range of 1.5 / 1 to 20 / 1.

[0071] The catalyst (C) is preferably added in the following amounts (based on net platinum metal): 0.1 to 1000 parts by weight per 1000 parts by weight of the total amount of compounds (A) and (B), and still more preferably 1 to 100 parts by weight.

[0072] The elastomer is advantageously a non-emulsified elastomer.

[0073] The term "non-emulsified" defines an organopolysiloxane elastomer that does not contain any hydrophilic chains, and in particular, does not contain any polyoxyethylene units (especially polyethylene oxide or polypropylene oxide) or any polyglycerol units.

[0074] Preferably, the organopolysiloxane elastomer particles are delivered in the form of a gel, as defined below, formed from an elastomer organopolysiloxane contained in at least one hydrocarbon oil and / or a silicone oil. In these gels, the organopolysiloxane particles can be spherical or non-spherical.

[0075] Spherical non-emulsified elastomers that can be used include, for example, those sold by Dow Corning under the names DC 9040, DC 9041, DC 9509, and DC 9505.

[0076] Also available are those sold by Shin-Etsu under the names KSG-6, KSG-15, KSG-16, KSG-18, KSG-41, KSG-42, KSG-43, and KSG-44; Gransil SR5CYC Gel, Gransil SR DMF 10 Gel, and Gransil SR DC556 Gel from Grant Industries' Gransil RPS company; and 1229-02-167, 1229-02-168, and SFE 839 from General Electric.

[0077] According to a preferred embodiment, the composition according to the invention comprises a non-emulsified elastomer as an organopolysiloxane elastomer transported in oil, preferably spherical, and preferably selected from compounds sold by Dow Corning under the names DC 9040, DC 9041, DC 9509, and DC 9505.

[0078] According to one particular embodiment, the elastomer can be used as a mixture with cyclic silicone oil. One example that can be mentioned is a mixture of crosslinked organopolysiloxane / cyclopentasiloxane or crosslinked organopolysiloxane / cyclohexasiloxane, such as Gransil RPS D5 or Gransil RPS D6 from Grant Industries.

[0079] Emulsified organopolysiloxane elastomer

[0080] According to another embodiment, the composition according to the invention comprises an emulsified elastomer as an organopolysiloxane elastomer transported in oil.

[0081] The term "emulsified organopolysiloxane elastomer" refers to an organopolysiloxane elastomer containing at least one hydrophilic chain, such as polyoxyalkylene organopolysiloxane elastomers and polyglycerolized silicone elastomers.

[0082] Emulsified organopolysiloxane elastomers can be selected from polyoxyalkylene-modified organopolysiloxane elastomers.

[0083] Polyoxyalkylene-based organopolysiloxane elastomers are crosslinked organopolysiloxane elastomers obtained by crosslinking addition reaction of a diorganopolysiloxane containing at least one hydrogen bonded to silicon with a polyoxyethylene containing at least two olefinically unsaturated groups.

[0084] Preferably, the polyoxyalkylene-based organopolysiloxane elastomer is obtained by a crosslinking addition reaction of (A1) a diorganopolysiloxane containing at least two hydrogens each bonded to silicon and (B1) a polyoxyalkylene containing at least two olefinically unsaturated groups, particularly in the presence of a platinum catalyst, as described, for example, in patents US5 236 986 and US5 412004.

[0085] In particular, organopolysiloxanes can be obtained by reacting polyoxyethylene (especially polyethylene oxide and / or polypropylene oxide) containing dimethylvinylsiloxy end groups with methylhydropolysiloxanes containing trimethylsiloxy end groups in the presence of a platinum catalyst.

[0086] The organic group bonded to the silicon atom in compound (A1) can be an alkyl group containing 1 to 18 carbon atoms, such as methyl, ethyl, propyl, butyl, octyl, decyl, dodecyl (or lauryl), myristyl, cetyl, or stearyl; a substituted alkyl group, such as 2-phenylethyl, 2-phenylpropyl, or 3,3,3-trifluoropropyl; an aryl group, such as phenethyl; and a substituted monovalent hydrocarbon group, such as an epoxy group, a carboxylic acid ester group, or a mercapto group.

[0087] Therefore, compound (A1) can be selected from methylhydropolysiloxanes containing trimethylsiloxy end groups, dimethylsiloxane-methylhydrosiloxane copolymers containing trimethylsiloxy end groups, dimethylsiloxane-methylhydrosiloxane cyclic copolymers, and dimethylsiloxane-methylhydrosiloxane-lauryl methylsiloxane copolymers containing trimethylsiloxy end groups.

[0089] Advantageously, polyoxyalkylene-based organopolysiloxane elastomers can form divinyl compounds, particularly polyoxyalkylene compounds containing at least two vinyl groups (which react with the Si-H bonds of the polysiloxane).

[0090] Polyoxyalkylene elastomers are particularly described in patents US 5236986, US 5412004, US 5837793 and US5811487, the contents of which are incorporated herein by reference.

[0092] Emulsified organopolysiloxane elastomers can also be selected from polyglycerolized organopolysiloxane elastomers.

[0093] The polyglycerolized organopolysiloxane elastomer according to the present invention is an organopolysiloxane elastomer that can be obtained by crosslinking addition reaction of a diorganopolysiloxane containing at least one silicon-bonded hydrogen with a polyglycerolized compound containing an olefinically unsaturated group, especially in the presence of a platinum catalyst.

[0095] In particular, organopolysiloxanes can be obtained by reacting a polyglycerol compound containing a dimethylvinylsiloxy end group with a methylhydropolysiloxane containing a trimethylsiloxy end group in the presence of a platinum catalyst.

[0096] Compound (A2) is the basic reactant for forming organopolysiloxane elastomers, and crosslinking is carried out through the addition reaction of compound (A2) and compound (B2) in the presence of catalyst (C2).

[0097] Compound (A2) is particularly an organopolysiloxane containing at least two hydrogen atoms bonded to different silicon atoms in each molecule.

[0098] Compound (A2) can have any molecular structure, especially linear or branched chain structures or cyclic structures.

[0099] Compound (A2) can have a viscosity ranging from 1 to 50,000 centipoise at 25°C, which is particularly convenient for miscibility with compound (B2).

[0100] The organic group bonded to the silicon atom in compound (A2) can be an alkyl group containing 1 to 18 carbon atoms, such as methyl, ethyl, propyl, butyl, octyl, decyl, dodecyl (or lauryl), myristyl, cetyl, or stearyl; a substituted alkyl group, such as 2-phenylethyl, 2-phenylpropyl, or 3,3,3-trifluoropropyl; an aryl group, such as phenyl, tolyl, or xylyl; a substituted aryl group, such as phenethyl; and a substituted monovalent hydrocarbon group, such as an epoxy group, a carboxylic acid ester group, or a mercapto group.

[0231] 2) Then mix the remaining portion of the oil-soluble component with the remaining portion of the oil phase and the ground pigment material until a homogeneous mixture is obtained;

[0232] 3) Add the organopolysiloxane elastomer to the mixture mentioned above while stirring, then incorporate the ground pigment material into the mixture and continue homogenizing until the mixture is homogeneous;

[0233] 4) Add filler, film-forming agent, co-preservative, antioxidant, active ingredient, and fragrance while stirring until homogeneous;

[0234] 5) Finally, pour the obtained composition into a small container and then leave it at ambient temperature for 24 hours.

[0235] Evaluate:

[0236] The spreadability, gloss, and weight of the prepared composition were evaluated.

[0237] Spreadability

[0238] Spreadability is used to evaluate whether a lip composition can be easily and smoothly glided on the lips during application.

[0239] Spreadability was evaluated by five experts as follows: The lip composition was slowly applied to both sides of the upper lip twice using the same force, while carefully feeling the force between the lip composition and the lips during the second application. The less friction, the better the spreadability.

[0240] gloss and thickness

[0241] Glossiness is used to assess the degree or brightness of light reflection on the lips under standard light.

[0242] Thickness is used to assess the feeling of weight on the lips caused by a lip product. It's a feeling of heaviness on the lips and a lack of freedom to breathe.

[0243] Five experts evaluated the gloss and thickness of the lipstick by applying it twice to both sides of the upper lip using the same pressure. After application, the lips were left untouched for 3 minutes, and the degree or brightness of light reflection on the center of the upper lip was examined under standard light, along with the thickness. The lower the light reflection or brightness, the lower the gloss and the better the matte finish. Less thickness was also better.

[0244] Finally, experts will provide evaluations or scores on spreadability, gloss, and thickness based on the following criteria, and the average value will be taken:

[0245] 5: Excellent;

[0246] 4: Basically good;

[0247] 3: Acceptable;

[0248] 2: Slightly worse and unacceptable;

[0249] 1: Poor, unacceptable.

[0250] The evaluation results of each lip composition are summarized in Table 3.

[0253] As can be seen, the lip composition of the invention has good spreadability and can leave a matte and lightweight deposit on keratin materials.
