Description

Title of the invention: SILICONE / HYDROCARBON-BASED COSMETIC COMPOSITIONS Technical field

[0001] The present disclosure relates to cosmetic compositions, and in particular to silicone / hydrocarbon based cosmetic compositions for the lips which also contain a styrenic block copolymer. CONTEXT

[0002] Styrenic block copolymer (SBC) / silicone systems are commonly used in conventional lip gloss products. Due to the nature of SBC chemistry, usage levels are low to maintain good application and reduce tack. Increasing usage levels results in SBC / silicone systems that do not settle at elevated temperatures, resulting in syneresis of the silicone and sedimentation of any pigment, filler, or pearlizing agent.

[0003] Thus, a cosmetic system that allows for increased utilization levels of an SBC while maintaining stability and preventing syneresis and / or sedimentation is useful and desirable. BRIEF SUMMARY

[0004] The present invention discloses a composition that provides such improved stability. Cosmetic compositions, such as those intended for application to the lips, may include a first phase that includes at least about 8% by weight of a thermoplastic block copolymer comprising styrenated blocks, and at least one hydrocarbon oil. The composition may include a second phase that includes at least 20% of a viscous silicone such as a dimethicone. To provide the necessary stability for these systems, the compositions utilize a filler that includes both a hectorite and a silica silylate, where the hectorite is disteardimonium hectorite, stearalkonium hectorite, or both.

[0005] In some embodiments, the dimethicone may include a plurality of dimethicones. In some embodiments, the plurality of dimethicones may include a first dimethicone having a molecular weight of less than 1,500 g / mol (such as cetyl dimethicone, with a molecular weight of 1,000 g / mol), and a second dimethicone having a molecular weight of greater than 2,000 g / mol (such as trimethylsiloxyphenyl dimethicone with a molecular weight of 3,000 g / mol). In some embodiments, the first dimethicone may be present at less than 10% by weight of the composition, and a second dimethicone is present at greater than 15% by weight of the composition. In some embodiments, the average weighted average of the molecular weights of the plurality of dimethicones is at least 7,000 g / mol. In some embodiments, the dimethicone may include a first dimethicone that is a polyalkyldimethicone, and a second dimethicone that contains at least one aryl group.

[0006] In some embodiments, the thermoplastic block copolymer may be present in an amount of at least 10% by weight of the composition.

[0007] In some embodiments, the composition may include at least 0.5% by weight of the hectorite. In some preferred embodiments, the composition may include at least 1% by weight of the hectorite. In some more preferred embodiments, the composition may include 1.5% to 2.5% by weight of the hectorite.

[0008] In some embodiments, the hydrocarbon oil comprises a saturated or unsaturated polyolefin, such as hydrogenated polyisobutene.

[0009] In some embodiments, the composition may include a pigment, a pearlizing agent, or a combination thereof. In some embodiments, the composition may include a thickener, an olfactory sensory agent, a solvent, a preservative, a butter, an ester, or a combination thereof. In some embodiments, the composition may include a fatty compound having a melting point in the range of 30°C to 50°C, such as Butyrospermum Parkii (Shea) butter and / or Bis-diglyceryl polyacyladipate-2.

[0010] In some embodiments, a storage modulus at a temperature of 55°C divided by a storage modulus at a temperature of 25°C is greater than or equal to 0.08.

[0011] In some embodiments, the ratio of the amount of hectorite to the amount of silica silylate is between 0.25:1 and 1:1.

[0012] In some embodiments, a method is disclosed for providing a high-shine, low-tack lip composition. The method includes forming a dual-phase product on the lips from a single product by applying a composition according to the invention and fragmenting the composition such that it forms a first layer comprising the thermoplastic block copolymer in contact with the lips and a second layer comprising the dimethicone on top of the first layer.

[0017] In this document, the terms “comprising”, “having” and “including” are used in their open and non-limiting sense.

[0018] Thus, the phrase "a mixture thereof" also refers to "mixtures thereof." Throughout the disclosure, the phrase "a mixture thereof" is used, after a list of elements as shown in the following example where the letters A through F represent the elements: "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture thereof." The phrase "a mixture thereof" does not require that the mixture include all of elements A, B, C, D, E, and F (although all of elements A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of two or more of elements A, B, C, D, E, and F may be included. In other words, it is equivalent to the expression "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E and F".

[0019] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.

[0020] The term "free" or "completely free of (a component)" as defined herein means that the systems or compositions do not contain the component to any degree measurable by standard means.

[0021] The term "substantially free of (a component)" as defined herein means that the systems or compositions contain no appreciable amount of the component, e.g., not more than about 1 wt%, or not more than about 0.5 wt%, or not more than about 0.3 wt%, such as not more than about 0.1 wt%, based on the weight of the system or composition comprising the system and / or the oxidizing composition according to embodiments of the disclosure.

[0022] Except in the working examples, or where otherwise indicated, all numbers expressing the amounts of ingredients and / or reaction conditions may be modified in all cases by the term "about", i.e. to within + / -5% of the number indicated.

[0023] In this document, all ranges provided are intended to include all specific ranges within the given ranges, as well as combinations of sub-ranges therein. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as sub-ranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc.

[0024] All components and elements positively presented in this disclosure may be negatively excluded from the claims. In other words, the cosmetic compositions of the present disclosure may be free or substantially free of all components and elements positively recited in this disclosure.

[0025] The present invention discloses a cosmetic composition, which may be a composition for application to the lips. The composition may include a first phase that includes: (1) at least about 8% by weight of the composition of a thermoplastic block copolymer comprising styrenated blocks; and (2) at least one hydrocarbon oil. The composition may include a second phase that contains at least 20% by weight of the composition of a viscous silicone, which may be a dimethicone. The composition may include a filler, where the filler includes both a hectorite and a silica silylate.

[0026] In some embodiments, these compositions are in the form of a gel.

[0027] Preferably, these compositions may be free of water. In some embodiments, these compositions may be substantially free of water.

[0028] Preferably, these compositions may be free of emulsifier. In certain embodiments, these compositions may be substantially free of emulsifier.

[0029] Referring briefly to [Fig. 1], a simplified illustration of the composition can be seen. In [Fig. 1], the composition 100 is seen to comprise a first phase 110, an oil phase containing a thermoplastic block copolymer comprising a styrenated block and a hydrocarbon oil. The composition also includes a second phase 120 which comprises the silicones. The second phase is dispersed within / encapsulated by the first phase. It can be seen that the second phase does not form spherical droplets as would be expected, for example, in a water-in-oil emulsion. Rather, these droplets are seen as discrete, non-spherical volumes contained within the first phase when viewed under a microscope. The filler 130 is present to stabilize the composition, and other components, including, for example, particles 140 such as pigments, may be present.

[0030] Thermoplastic Block Copolymer Comprising Styrene Blocks

[0031] In some embodiments, the composition may include one or more thermoplastic block copolymers comprising styrene blocks. In some embodiments, the one or more thermoplastic block copolymers may consist of a single thermoplastic block copolymer. In some embodiments, the one or more thermoplastic block copolymers thermoplastics may consist of a plurality of thermoplastic block copolymers.

[0032] The block copolymers of the present invention are characterized by the presence of at least one "hard" segment and at least one "soft" segment. Apart from their compositional nature, the hard and soft segments of the block copolymers of the present invention can be defined in terms of their respective glass transition temperatures, Tg. The hard segment can have a Tg of 50°C or higher, while the soft segment can have a Tg of 20°C or lower. The Tg of the hard block can range from 50°C to 150°C. The Tg of the soft block can range from -150°C to 20°C.

[0033] The block copolymers useful in the compositions of the present invention may be thermoplastic elastomers. The hard segments of the thermoplastic elastomer typically comprise vinyl monomers in varying amounts. Examples of suitable vinyl monomers include, but are not limited to, styrene as well as other optional monomers including methacrylate, acrylate, vinyl ester, vinyl ether, vinyl acetate, and the like.

[0034] The soft segments of the thermoplastic elastomer comprise olefin polymers and / or copolymers which may be saturated, unsaturated, or combinations thereof. Suitable olefin copolymers may include, but are not limited to, ethylene / propylene copolymers, ethylene / butylene copolymers, propylene / butylene copolymers, polybutylene, polyisoprene, polymers of hydrogenated butanes and isoprenes, and mixtures thereof.

[0035] The thermoplastic elastomers useful in the present invention are block copolymers, for example, diblock, triblock, multiblock, radial, and star block copolymers, and blends thereof. A diblock thermoplastic elastomer is generally defined as an AB type or a hard segment (A) followed by a soft segment (B) in a block. A triblock is generally defined as an ABA type copolymer or a ratio of a hard segment, a soft segment, and a hard segment. Multiblock or radial block or star block thermoplastic elastomers usually contain any combination of hard and soft segments, provided that the elastomers possess both hard and soft characteristics.

[0036] In some embodiments, the thermoplastic elastomer of the present invention may be selected from the class of KRATON rubbers (Kraton Corporation of Houston, Textile) or similar thermoplastic elastomers. KRATON rubbers are thermoplastic elastomers in which the polymer chains have a diblock, triblock, multiblock, or radial or star-shaped block configuration or many mixtures thereof. KRATON triblock rubbers have polystyrene (hard) segments at each end of a (soft) rubber segment, while KRATON diblock rubbers have a (hard) polystyrene segment attached to a (soft) rubber segment. The radial or star configuration of KRATON can be a four-point star or other multi-point rubber star, with a polystyrene segment attached to each end of a rubber segment. The configuration of each of the KRATON rubbers forms separate domains of polystyrene and rubber.

[0037] Each KRATON rubber molecule is said to comprise block segments of styrene monomer units and rubber monomer and / or comonomer units. The most common structure for the KRATON triblock copolymer is the linear block type ABA: styrene-butadiene-styrene, styrene-isoprene-styrene, styrene-ethylenepropylene-styrene, or styrene-ethylenebutylene-styrene. The KRATON diblock is preferably of the block type AB such as styrene-ethylenepropylene, styrene-ethylenebutylene, styrene-butadiene, or styrene-isoprene. The configuration of the KRATON rubber is well known in the art and any block copolymer elastomer having a similar configuration is within the scope of the invention. Other block copolymers are sold under the brand name Septon (which represents elastomers known as SEEPS, sold by Kurary, Co., Ltd) and those sold by ExxonMobil Chemical under the brand name VECTOR.

[0038] Other thermoplastic elastomers useful in the present invention include block copolymer elastomers comprising a styrene-butylene / ethylene-styrene copolymer (triblock), an ethylene / propylene-styrene copolymer (radial or star block), or a mixture of the two. (Some manufacturers refer to the block copolymers as hydrogenated block copolymers, e.g., hydrogenated styrene-butylene / ethylene-styrene copolymer (triblock)).

[0039] The compositions of the present invention include at least one block copolymer, for example diblock, triblock, multiblock or radial block copolymers, and mixtures thereof. The at least one block copolymer comprises at least one styrene block and may further comprise at least one block comprising units selected from butadiene, ethylene, propylene, butylene and isoprene or a mixture thereof.

[0040] Diblock copolymers that may be mentioned include, but are not limited to, styrene / ethylene-propylene copolymers (comprising a styrene block and a block obtained from ethylene and propylene), styrene / ethylene-butylene copolymers, styrene-ethylene / butadiene copolymers, styrene / butadiene copolymers and styrene / isoprene copolymers.

[0041] In some notable embodiments, the block copolymer includes styrene blocks and one or more blocks selected from: the blocks butadiene, isoprene blocks and ethylene-butylene blocks. In other embodiments, the block copolymer includes (1) styrene blocks and butadiene blocks; or (2) styrene blocks and ethylene-butadiene blocks; or (3) styrene and isoprene blocks.

[0042] Triblock copolymers that may be mentioned include, but are not limited to, styrene / ethylene-propylene / styrene copolymers, styrene / ethylene-butylene / styrene copolymers, styrene / ethylene-butadiene / styrene copolymers, styrene / isoprene / styrene copolymers, and styrene / butadiene / styrene copolymers. For example, triblock polymers sold under the names KRATON G1650, KRATON G1652, KRATON DI 101, KRATON DI 102, and KRATON, commercially available from Kraton Polymers.

[0043] For example, a blend of a diblock copolymer and a triblock copolymer may be used as the block copolymer. According to at least one embodiment, the diblock copolymer and the triblock copolymer may be selected from block copolymers comprising at least one styrene block and at least one block comprising units selected from butadiene, ethylene, propylene, butylene and isoprene. In one embodiment, the block copolymer comprises from about 50% to about 90% triblocks and from about 10% to about 50% diblocks.

[0044] Examples of suitable block copolymers include the Kraton G series, such as Kraton G1701 (INCI name hydrogenated styrene / isoprene copolymer) and KRATON G1657 (HYDROGENATED STYRENE / BUTADIENE COPOLYMER). KRATON G1657 (styrene-ethylene / butylene-styrene triblock and 30% styrene-ethylene-butylene diblock); INCI: HYDROGENATED STYRENE / BUTADIENE COPOLYMER; a blend of 70% styrene-ethylene-butylene triblock) is particularly notable.

[0045] It is preferred that the styrene content of the block copolymer be less than 30% by weight, preferably less than 25% by weight, and more preferably less than 20% by weight, and more preferably from about 5% to about 15%, based on the weight of the block copolymer. This is due to the tendency of block copolymers having a styrene content greater than 30% by weight to harden / gel in conventional support systems.

[0046] In some embodiments, the thermoplastic block copolymer(s) comprising styrenated blocks may be present in the cosmetic composition in a total amount ranging, for example, from about 8% to about 30% by weight; such as from about 9% to about 25% by weight; or such as from about 10% to about 20%, based on the weight of the composition.

[0047] In some embodiments, the thermoplastic block copolymer is present in the first phase in an amount of at least 10% by weight of the composition. Hydrocarbon oil

[0048] In some embodiments, the composition may include one or more hydrocarbon oils. In some embodiments, the composition may include a plurality of hydrocarbon oils. In some embodiments, each hydrocarbon oil is a non-volatile oil.

[0084] The ratio of hectorite to silica silylate may vary, but the concentrations are typically in the same order of magnitude. In some embodiments, the ratio of silica silylate (in wt%) to hectorite (in wt%) may be 4:1 to 1:1. In some embodiments, the ratio is 3:1 to 1:1, 2:1, 1.5:1, or 1.25:1. In some preferred embodiments, the ratio is 1:1.

[0085] In some embodiments, the total amount of silica hectorite plus silylate represents at least 10% of the total amount of viscous silicone in the system. In some embodiments, the total amount of silica hectorite plus silylate represents at least 12% of the total amount of viscous silicone in the system. In some embodiments, the total amount of silica hectorite plus silylate represents at least 15% of the total amount of viscous silicone in the system.

[0088] In some embodiments, hectorite is present in the composition in a total amount of at least 0.5% by weight of the composition, preferably at least 1% by weight, and more preferably at least 2% by weight. In some embodiments, hectorite is present in the composition in a total amount of up to 2%, 2.5%, 3%, 3.5%, 4% or 5% by weight of the composition. In some embodiments, hectorite is present in the composition in a total amount of 1.5% to 2.5% by weight of the composition.

[0089] Silica silylate

[0090] In some embodiments, the composition may include a silica silylate. In some embodiments, the silica silylate is silylated silica aerogel particles (INCI name: silica silylate), which are hydrophobic silica aerogel particles. Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air. The preparation of hydrophobic silica aerogel particles whose surface has been modified by silylation is described in more detail in U.S. Patent No. 7,470,725.

[0091] In some embodiments, hydrophobic silica aerogel particles surface-modified with trimethylsilyl groups may be selected. For example, the aerogel sold as VM-2260® by Dow Corning, the particles of which have an average particle size of about 1,000 microns and a specific surface area per unit weight of from 600 to 800 m2 / g, or the aerogel sold as VM-2270®, also by Dow Corning, the particles of which have an average particle size of from 5 to 15 microns and a specific surface area per unit weight of from 600 to 800 m2 / g, may be selected.

[0092] In some embodiments, the silica silylate is present in the composition in a total amount of at least 0.5% by weight of the composition, preferably at least 1% by weight, and more preferably at least 2% by weight. In some embodiments, the hectorite is present in the composition in a total amount of up to 2%, 2.5%, 3%, 3.5%, 4% or 5% by weight of the composition.

[0093] In some embodiments, the silica silylate is present in the composition in a total amount of 1.5% to 2.5% by weight of the composition. Other components

[0094] The compositions may include other components. In some embodiments, the compositions may include a tackifying agent. In some embodiments, the compositions may include a thickening agent ("thickener"), an olfactory sensory agent, a solvent, a preservative, an antioxidant, a butter, an ester, or a combination thereof. In some embodiments, the compositions may include a pigment, a pearlizing agent, or a combination thereof. In some embodiments, the composition may include a fatty compound having a melting point in the range of 30°C to 50°C.

[0095] In some embodiments, the composition may comprise or consist of a thermoplastic block copolymer, a hydrocarbon oil, a dimethicone, a hectorite, a silica silylate, a tackifier, a thickener, an olfactory sensory agent, a solvent, a preservative, an antioxidant, a fatty compound having a melting point in the range of 30°C to 50°C, a colorant (such as a pigment or a pearlizing agent), or a combination thereof, and may be free or substantially free of any other materials. Sticky agent

[0096] In some embodiments, the composition may include a "tackifying" resin, called a tackifying agent. Such resins are described in particular in the Handbook of Pressure Sensitive Adhesive, edited by Donatas Satas, 3rd edition, 1989, pages 609 to 619. The resin of the composition according to the invention is selected from rosin, rosin derivatives, hydrocarbon resins and mixtures thereof. Preferably, the resin is an indene hydrocarbon resin which may optionally be hydrogenated.

[0097] Rosin is a mixture comprising mainly organic acids called resin acids (mainly abietic and pimaric acids). There are three types of rosin: gum rosin, which is obtained by incision on living trees, wood rosin, which is extracted from pine stumps or wood, and tall oil (pine oil rosin), which is obtained from a by-product of papermaking.

[0098] Rosin derivatives may result in particular from the polymerization, hydrogenation and / or esterification (for example with polyalcohols, such as ethylene glycol, glycerol or pentaerythritol) of resin acids.

[0140] By way of illustration of the pearlescent agents which can be introduced as interference pigment in the first composition, mention may be made of the gold-colored pearlescent agents sold in particular by BASF under the name Brilliant Gold 212G (Timica), Gold 222C (Cloisonne), Sparkle Gold (Timica) and Monarch Gold 233X (Cloisonne); the bronze pearlescent agents sold in particular by Merck under the names Bronze Fine (17384) (Colorona) and Bronze (17353) (Colorona) and by BASF under the name Super Bronze (Cloisonne); the orange pearlescent agents sold in particular by BASF under the name Orange 363C (Cloisonne) and by Merck under the names Passion Orange (Colorona) and Matte Orange (17449) (Microna); brown pearlescent agents sold in particular by BASF under the names Nu-Antique Copper 340XB (Cloisonne) and Brown CL4509 (Chroma-lite); copper-tinted pearlescent agents sold in particular by BASF under the name Copper 340A (Timica);red-tinted pearlescent agents sold in particular by Merck under the name Sienna Fine (17386) (Colorona); yellow-tinted pearlescent agents sold in particular by BASF under the name Yellow (4502) (Chroma-lite); red-tinted pearlescent agents with a gold tint sold in particular by BASF under the name Sunstone G012 (Gemtone); pink-tinted pearlescent agents sold in particular by BASF under the name Tan Opal G005 (Gemtone); black-tinted pearlescent agents with a gold tint sold in particular by BASF under the name Nu-Antique Bronze 240 AB (Timica); blue-tinted pearlescent agents sold in particular by Merck under the name Matte Blue (17433) (Microna); white-tinted pearlescent agents with a silver tint sold in particular by Merck under the name Xirona Silver; and orange-pinkish-golden green pearlescent agents sold in particular by Merck under the name Indian Summer (Xirona); and mixtures thereof.

[0141] Goniochromatic pigments

[0142] In this document, the term "goniochromatic pigment" designates a pigment which makes it possible to obtain, when the composition is spread on a substrate, a chromatic distance in the a*b* plane of the CIE 1976 colorimetric space which corresponds to a variation Dh° of the hue angle h° of at least 20° when the angle observation varies from normal between 0° and 80°, for an angle of incidence of light of 45°.

[0143] The chromatic distance can be measured, for example, using a spectrogonioreflectometer of the Instrument Systems brand and with the reference GON 360 Goniometer, after spreading the composition in the fluid state over a thickness of 300 qm using an automatic spreader on a contrast paper of the Erichsen brand and with the reference Type 24 / 5, the measurement being carried out on the black background of the paper.

[0144] The goniochromatic pigment may be chosen, for example, from multilayer interference structures and liquid crystal dyes.

[0145] In the case of a multi-layer structure, the latter may comprise, for example, at least two layers, each layer being made, for example, from at least one material chosen from the group consisting of the following materials: MgF2, CeF3, ZnS, ZnSe, Si, SiO2, Ge, Te, Fe2O3, Pt, Va, A12O3, MgO, Y2O3, S2O3, SiO, HfO2, ZrO2, CeO2, Nb2O5, Ta2O5, TiO2, Ag, Al, Au, Cu, Rb, Ti, Ta, W, Zn, MoS2, cryolite, alloys, polymers and combinations thereof.

[0146] The multilayer structure may or may not have, with respect to a central layer, a symmetry with respect to the chemical nature of the stacked layers.

[0147] Different effects are obtained depending on the thickness and nature of the various layers.

[0148] Examples of symmetrical multilayer interference structures are, for example, the following structures: Fe2O3 / SiO2 / Fe2O3 / SiO2 / Fe2O3, a pigment having this structure being sold under the name Sicopearl by BASF; MoS2 / SiO2 / mica-oxide / SiO2 / MoS2; Fe2O3 / SiO2 / mica-oxide / SiO2 / Fe2O3; TiO2 / SiO2 / TiO2 and TiO2 / Al2O3 / TiO2, pigments having these structures being sold under the name Xirona by Merck.

[0149] Dyes for liquid crystals include, for example, silicones or cellulose ethers onto which mesomorphic groups are grafted. Examples of liquid crystal goniochromatic particles that can be used are those sold by Chenix and those sold under the name Helicone® HC by Wacker.

[0150] It is also possible to use, as goniochromatic pigment, certain pearlescent agents, pigments with effects on a synthetic substrate, in particular a substrate of the alumina, silica, borosilicate, iron oxide or aluminum type, or interference flakes resulting from a polyethylene terephthalate film.

[0151] In particular, as non-limiting examples of goniochromatic pigments, alone or in a mixture, mention may be made of the goniochromatic pigments SunShine® sold by Sun Chemical, Cosmicolor Celeste® from Toyo Aluminum KK, Xirona® from Merck and Reflecks Multidimensions® from BASF.

[0152] The composition according to the invention may also comprise one or more shades.

[0153] Among the liposoluble dyes, mention may be made in particular of fluorinated dyes such as, for example, Sudan red, FDC Red 4, DC Red 17, Red 21, Red 27, DC Green 6, Sudan brown, Yellow 10, DC Yellow 11, DC Violet 2, DC Orange 4, DC Orange 5, yellow quinoline, or mixtures thereof.

[0154] In some embodiments, the composition is preferentially chosen so as to provide a particular rheological profile. In particular, a storage modulus of the composition at an elevated temperature of 55°C divided by a storage modulus at a temperature of 25°C may be greater than or equal to 0.07, preferably at least 0.08, more preferably at least 0.09, even more preferably at least 0.10, and most preferably at least 0.15.

[0155] This can be seen with reference to [Fig. 2]. In [Fig. 2], two nearly identical formulations were tested. The first was an exemplary formulation that included 2% disteardimonium hectorite and 2% silica silylate, with the remainder being a base composed of 20-30% of a combination of two dimethicones, 8-12% of a thermoplastic block copolymer, 35-40% of a combination of hydrocarbon oils, and the remainder various other components as disclosed herein. The second formulation was a comparative formulation, where the disteardimonium hectorite was replaced with a different filler, lauroyl lysine. As seen in [Fig. 2], the storage modulus of the exemplary composition at 55°C remains relatively high compared to the modulus of the comparative formulation using lauroyl lysine.More specifically, in this example, the resulting quotient, sometimes called G'DECay, of dividing the storage modulus at 55°C by the storage modulus at 25°C, is 0.196 for the exemplary formula, and 0.0248 for the comparative formula.

[0156] Test Method: After producing the compositions, the modulus values ​​were determined at 25°C, with a controlled stress rheometer (e.g., a Haake RS 150) equipped with a sandblasted titanium body with an anti-evaporation device and a 40 mm / 0 sandblasted parallel plate measuring body with the following conditions: no preshear, 30 s temperature equilibration at 25°C, temperature ramp from 25°C to 70°C, 3°C / min, applied stress 0.2% at a> = 1.0 s'.

[0157] With the values ​​available, G'decay can be calculated by dividing the value at an elevated temperature (e.g. 55°C is thus divided by the temperature at 25°C). Note that in some embodiments, this may be represented as a percentage.

[0158] In some embodiments, an alternative approach may be to divide the storage modulus (G') at elevated temperature by the storage modulus of the composition at the initial point, then multiply by 100, to obtain a "relative" value as a percent change, sometimes referred to as G'reL. Example 1

[0159] The compositions listed in Table 1 were produced by combining the components at 90 to 95°C, mixing until uniform, and allowing them to cool. Uses are listed as wt% of the total composition. In some examples, a silica silylate that was spherical and had an oil absorbance ranging from about 2 mL / g to about 12 mL / g was used ("silica silylate 1"). Because of the broad range of performance, this may sometimes be referred to as a "low oil absorbance" silica silylate. In some examples, a silica silylate with irregularly shaped particles and having an oil absorbance of at least about 6 mL / g was used ("silica silylate 2"), i.e., a "high oil absorbance" silica silylate. Dimethicones include cetyl dimethicone and trimethylsiloxyphenyl dimethicone in an approximate ratio of 1:4.Hydrocarbon oils include three polar oils and two nonpolar oils in a ratio of about 1:1.15, including esters, and a saturated or unsaturated polyolefin. Other materials include two low-melting temperature fatty compounds in a total amount greater than 10%, solvents, a preservative, a tackifier, and a thickener.

[0161] Various embodiments of the present disclosure are shown as exemplary formulas (Ex-1, Ex-2 and Ex-3), together with comparative formulas (C1, C-2, C-3, C-4 and C-5).

[0162] The above formulas were compared using the rheological test method disclosed herein for comparing a storage modulus at 55°C to a storage modulus at 25°C. [Fig.3] shows the results in graphical form, where the storage modulus values ​​for the eight compositions are shown: Ex-1 (ref. 301, solid line), Ex-2 (ref. 302, dotted line), Ex-1 (ref. 303, short dashed line), Cl (ref. 304, medium dashed line), C-2 (ref. 305, long dashed line), C-3 (ref. 306, dotted and mixed line) medium lines), C-4 (ref. 307, mixed dotted and long line), and C-5 (ref. 308, mixed double dotted and long line). The G'DECay values ​​calculated from these are summarized in Table 2, below.

[0163] The formulas were also placed in a stability chamber maintained at a temperature of 55°C for one week, after which the samples were visually assessed to determine if sedimentation / syneresis had occurred. The results are summarized in Table 2, below.

[0164] [Tables2] Test Ex-1 Ex-2 Ex-3 Cl C-2 C-3 C-4 C-5 G'dëCAY 0.196 0.0810 0.0986 0.0248 0.0222 0.0130 0.0498 0.0579 Visual sedimentation No No Minor Severe Severe Severe Severe

[0165] As seen, the use of the two disclosed hectorites, together with the claimed amount of silica silylate, surprisingly yields stable formulations. There is a clear division in G'decay, between those with severe sedimentation / syneresis problems and those with improved performance. As seen, embodiments of the composition have G'decay values ​​> 0.08. In this example, the values ​​are between 0.08 and 0.2, and all show a significant improvement in sedimentation / syneresis over other comparative formulations with a G'DECay of less than 0.08.

[0166] Surprisingly, using other fillers to replace hectorites does not work. For example, replacing disteardimonium hectorite with any other filler, such as fumed silica (C-3), kaolin (C-2), or lauroyl lysine (Cl), results in severe sedimentation / syneresis problems. Removing silica silylate (C-4) also results in severe sedimentation / syneresis problems.

[0167] Without being bound by any theory, it should be noted that a usage level of 0.5% by weight of the hectorite may sometimes be insufficient, depending on the particle shape and / or the oil absorbance capacity of the silica silylate. When using 0.5% of a hectorite and 2% of a silica silylate with a lower oil absorbance (C-5), the formula is always unstable with severe sedimentation / syneresis problems, while 0.5% of the hectorite and 2% of a silica silylate with a consistently higher oil absorbance (Ex-3), the formula is borderline stable, with only minor sedimentation / syneresis problems.

[0168] Also disclosed is a method for providing a stable, high gloss, low stickiness lip composition. The method uses a composition as disclosed herein. The method includes forming a product to dual phase on the lips from a single application of a product by applying a composition as disclosed herein, fragmenting the composition such that it forms a first layer comprising the thermoplastic block copolymer in contact with the lips and a second layer comprising the dimethicone on top of the first layer.

[0169] As seen in [Fig.4], when applied to the lips 410 of a person 400, the product forms a first layer 420 in contact with the lips 410, and a second layer 430 in contact with the first layer 410.

[0170] Those skilled in the art will recognize or be able to establish, simply by using routine experimentation, numerous equivalents to the specific embodiments of the invention described herein. These equivalents are intended to be encompassed by the following claims.
