Silicone mixtures for hair conditioning

Abstract

The hair conditioner composition utilizes a blend of polyquaternium silicone nanoemulsion and silicone oil to provide improved conditioning benefits and composition stability. The composition may also contain a cationic surfactant, a fatty alcohol, and an aqueous carrier. When the polyquaternium silicone nanoemulsion and silicone oil are blended in the appropriate ratio, the composition provides improved hair free flow and exhibits good stability.

Description

[Technical Field]

[0001] The present disclosure relates generally to hair conditioning compositions comprising a blend of a silicone nanoemulsion and a silicone oil. More specifically, the present disclosure is directed to hair conditioning compositions containing a blend of a polyquaternium silicone nanoemulsion and a silicone oil, which exhibit improved conditioning and product stability. [Background technology]

[0002] Conventional hair conditioners generally contain silicone polymers to provide dry conditioning benefits, as well as high concentrations of high-melting-point fatty compounds (e.g., C16-C18 fatty alcohols), which act as structuring agents that combine with suitable surfactants and an aqueous carrier to form a gel network. The gel network provides a viscous, high-yield-point rheology, making it easy for consumers to dispense the conditioner from a bottle or tube and then distribute and spread the product throughout their hair. The gel network structure also allows for the incorporation of other common ingredients, such as silicones, fragrances, and oils, in the form of shelf-stable oil-in-water emulsions. These silicones and oils are intended to adhere to hair and provide key hair conditioning benefits, including reducing friction when combing, wet or dry, and making hair more manageable.

[0003] However, silicone polymers can build up on the hair over multiple uses, and high melting point fatty compounds can codeposit with the silicone, resulting in an undesirable waxy buildup on the hair. In fact, a major consumer complaint about hair conditioners is the waxy residue that makes hair look oily or feel heavy. Summary of the Invention [Problem to be solved by the invention]

[0004] Nanoemulsion silicones can be used to provide a cleaner hair feel with less buildup, but may exhibit reduced conditioning efficacy and reduced conditioner stability (e.g., visible phase separation). Therefore, it would be desirable to provide a hair conditioner with nanoemulsion silicones that provides good conditioning and has good stability. [Means for solving the problem]

[0005] Disclosed herein is a hair conditioner composition comprising a blend of a polyquaternium silicone nanoemulsion and a silicone oil. The polyquaternium silicone contained in the nanoemulsion has a particle size of 1 nm to 100 nm and contains silicone blocks of 80 to 250 siloxane units. The silicone oil has a particle size of 1 micron to 100 microns. The ratio of polyquaternium silicone to silicone oil in the blend ranges from 1:2 to 3:1. The hair conditioner composition may optionally contain a cationic surfactant that forms a gel network, a fatty alcohol, and an aqueous carrier. [Brief explanation of the drawings]

[0006] While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter of the invention, it is believed the present invention may be more readily understood from the following description taken in conjunction with the accompanying drawings. [Figure 1] 1 shows a microscopic view of silicone distribution in inventive and comparative conditioners. [Figure 2] 1 shows SEM images of hair treated with the inventive formula and a comparative formula. DETAILED DESCRIPTION OF THE INVENTION

[0007] The inventors have discovered that the use of a silicone nanoemulsion blended with a silicone oil results in improved hair free flow while still maintaining high conditioning and providing a stable product. Surprisingly, it has also been discovered that blending a polyquaternium silicone nanoemulsion with a silicone oil in a specific ratio and incorporating this blend into a hair conditioner composition results in improved dry conditioning without sacrificing product stability.

[0033] [ka] wherein R is an alkyl group (preferably, R is methyl or ethyl, more preferably methyl), and x is an integer up to 500 selected to achieve the desired molecular weight.

[0034] Commercially available dimethiconol is typically sold as a mixture with dimethicone and / or cyclomethicone (e.g., Dow Coming® 1401, 1402, and 1403 fluids). Silicones in this section may further include any of the silicones disclosed in U.S. Pat. No. 10,828,248.

[0035] Silicone Nanoemulsion Silicone nanoemulsions include nano-sized silicones, non-ionic emulsifiers, and carrier fluids. The active percentage of silicone in the emulsion can be 5% to 50%. Hair care compositions can include 0.5% to 50% (e.g., 3% to about 30%, or even 5% to 25%) of one or more silicone nanoemulsions by weight of the hair care composition. The active concentration of nano-sized silicones contained within the hair care composition can be 0.1% to 10% (e.g., 0.5% to 6% or 1% to 5%) by weight of the hair care composition.

[0036] Nano-sized silicone The particle size of the one or more nano-sized silicones in the hair care composition can be from 1 nm to 100 nm (e.g., from 5 nm to 80 nm, from 10 nm to 60 nm, from 12 nm to 50 nm, or even from 20 nm to 100 nm). In some cases, the particle size of the one or more silicones in the hair care composition can be from 1 nm to 500 nm (e.g., from 5 nm to 300 nm, from 8 nm to 200 nm, or even from 10 nm to 100 nm).

[0037] The particle size of nanoemulsion silicones can be measured by dynamic light scattering (DLS) using a measurement angle of 173° and the refractive index of one or more silicones. A Malvern Zetasizer Nano ZEN3600 system using a He-Ne laser at 633 nm can be used for measurements at 25°C. For each sample, three particle size measurements are performed and the Z-average value is reported as the particle size.

[0038] One or more silicones may be in the form of a nanoemulsion, i.e., an emulsion with a particle size of less than 100 nm. The nanoemulsion may include any silicone suitable for application to skin and / or hair. 25% to 99% (e.g., 25% to 75% or 25% to 50%) of the total silicones in the hair care composition may be in the form of a nanoemulsion. Silicones described herein may include those disclosed in WO 2019 / 126442.

[0039] In the nano-sized silicone contained in the nanoemulsion, at least one silicone may be a polyorganosiloxane compound containing one or more quaternary ammonium groups, a silicone block containing an average of 80 to 250 siloxane units, at least one polyalkylene oxide structural unit, and at least one terminal ester group.

[0040] The hair conditioning compositions herein may include a low viscosity silicone polymer having a viscosity of 100,000 centipoise (cP) or less. For example, the silicone polymer may have a viscosity of 1 cP to 50,000 cP, 25 cP to 30,000 cP, 50 cP to 25,000 cP, 100 cP to 20,000 cP, 150 cP to 15,000 cP, or even 200 cP to 13,000 cP.

[0041] Without being bound by theory, low-viscosity silicone polymers provide improved conditioning benefits over conventional silicones due to the addition of hydrophilic functional groups, such as quaternary amines, ethylene oxide / propylene oxide, etc. Compared to silicones with quaternary functional groups, these structures have significantly lower viscosities and do not require blending with other low-viscosity diluents and dispersants to enable formulation into products. Low-viscosity silicone solvents and diluents can often cause a trade-off between viscosity and stability in hair care products. Silicone polymers do not require these materials because their viscosity is low enough that they can be added directly or in emulsion form. Improved conditioning benefits include a smooth feel, reduced friction, and prevention of hair damage, and in some cases, eliminate the need for silicone blending.

[0042] Structurally, the silicone polymer can be a polyorganosiloxane compound containing one or more quaternary ammonium groups, at least one silicone block containing an average of 99 to 199 siloxane units, at least one polyalkylene oxide structural unit, and at least one terminal ester group. The silicone block can contain an average of 80 to 250 siloxane units (e.g., 110 to 199, 120 to 199, 130 to 199, 110 to 190, 130 to 190, 110 to 175, 120 to 175, 130 to 175, 110 to 155, 120 to 155, 130 to 155, 155 to 199, 155 to 190, or even 155 to 175). The average block length reflects an average value and can be determined, for example, by H-NMR spectroscopy or GPC using protocols known in the art.

[0043] The polyorganosiloxane compound can have a molar ratio of silicone to alkylene oxide blocks of 2:1 to 20:1 (eg, 4:1 to about 16:1, 6:1 to 12:1, or even 8:1 to 10:1).

[0044] The nitrogen content of the polyorganosiloxane compound can be 0.1 to 0.4 mmol N / g polymer (e.g., 0.1 to 0.3, 0.13 to 0.27, 0.13 to 0.35, 0.15 to 0.3, 0.17 to 0.27, or even 0.19 to 0.24 mmol N / g polymer).

Nonionic emulsifiers may be broadly defined as including compounds containing alkylene oxide groups (hydrophilic in nature) and hydrophobic compounds which may be aliphatic or alkylaromatic in nature. Examples of nonionic emulsifiers include alcohol ethoxylates, polyethylene oxide condensates of alkylphenols, condensation products of ethylene oxide and products obtained from the reaction of propylene oxide with ethylenediamine products, long-chain tertiary amine oxides, long-chain tertiary phosphine oxides, long-chain dialkyl sulfoxides containing one short-chain alkyl or hydroxyalkyl radical (usually methyl) of 1 to 3 carbon atoms and one long hydrophobic chain containing an alkyl, alkenyl, hydroxyalkyl, or ketoalkyl group containing 8 to 20 carbon atoms, 0 to 10 ethylene oxide moieties, and 0 or 1 glyceryl moiety, polysorbates (e.g., sucrose esters of fatty acids), alkylpolysaccharide nonionic emulsifiers (e.g., those disclosed in U.S. Pat.

Still other useful dimethicone copolyols include materials with a variety of cationic, anionic, amphoteric, and zwitterionic pendant moieties.

[0068] The nanoemulsions herein can be prepared by mechanical polymerization and / or emulsion polymerization. Mechanical polymerization techniques involve (1) dissolving a primary surfactant in water, (2) adding a silicone to form a two-phase mixture, and (3) slowly adding a co-surfactant to the two-phase mixture while mixing until a clear, isotropic microemulsion of siloxane in water is formed. Emulsion polymerization techniques involve adding (1) a polymer precursor (i.e., a water-immiscible monomer or reactive oligomer), (2) a surfactant to stabilize the polymer precursor droplets in water, and (3) a water-soluble polymerization catalyst (e.g., a strong mineral acid such as hydrochloric acid or a strong alkaline catalyst such as sodium hydroxide) to water and stirring. Polymerization is allowed to proceed until the reaction is complete or the desired degree of polymerization (DP) is reached, forming a polymer emulsion.

[0104] How to Condition Your Hair The method of conditioning hair described herein includes (1) preparing a hair care composition described herein, (2) applying the composition to the hair, and (3) rinsing the composition from the hair. Hair switches were also treated in the above manner for the tests performed below. [Example]

[0105] The following examples illustrate the hair care compositions and / or methods of conditioning hair described herein. The exemplary compositions can be prepared, for example, by conventional formulation and mixing techniques as described herein. Some components may be provided by the supplier as a dilute solution. The amounts stated represent the weight percent of active material unless otherwise specified.

[0106] The hair conditioning composition of the present invention does not accumulate on hair over time, does not make hair heavy, and surprisingly maintains good dry conditioning effect.It is believed that silicone particle size, its emulsifying system, and silicone type all cause this difference in deposition.First, silicone particle size and its emulsifying system determine how uniformly silicone is deposited for one cycle of use.However, over time, silicone properties, such as durable silicone ADM8100E (CC05 amodimethicone), are very difficult to wash off and accumulate over multiple cycles of use.Usually, conditioners with pure silicone also have this accumulation over multiple cycles of use.In contrast, polyquaternium silicone nanoemulsion, such as Momentive Waro Y20875, does not have this strong deposition property after blending with pure silicone, and can be washed off every time.

[0107] The conditioner compositions in Table 1 below were prepared by creating a conditioner base containing a fatty alcohol, a cationic surfactant, water, EDTA, and benzyl alcohol, followed by post-addition of silicone or blend and fragrance by centrifugal mixing. The conditioner base is made by heating a mixture of the fatty alcohol and cationic surfactant and in-line mixing with a water phase at high shear to form a conditioner gel network structure. Post-addition of silicone and fragrance was performed using a FlackTek SpeedMixer® at a mixing speed of 2000 rpm for 2 minutes.

[0108] [Table 1] * Momentive Y-14945 ** BTMS P8580KC manufactured by KCl Limited.

[0109] method IR Micro-Imaging (Transmission Mode) To visually assess the silicone distribution, FTIR microscopy was performed on the conditioner compositions. Samples were manually coated onto a 2 x 2 cm CaF2IR transparent crystal using cleaned microscope glass to form a thin film / coating, which was then allowed to dry in air for several hours before measurement.

[0110] Measurements were performed using a Bruker Vertex 80v FTIR with a Hyperion 3000 equipped with a 128 × 128 focal plane array (FPA) detector in transmission mode, using a 36X IR objective and a 15X IR condenser, from 4000 to 900 cm. -1 With a minimum of 1024 scans and a resolution of 8cm -1 The background is collected on an empty CaF2 crystal before the sample measurement. For each sample, measurements are performed on 2x2 adjacent single images of the sample (tile) on three replicates from different random areas on the CaF2 substrate.

[0111] Initial spectral processing was performed with Bruker OPUS software version 6.0 or higher, and spectra were analyzed from 3800 to 950 cm -1 The linear generation is from 1900 to 2500 cm -1 The image was cropped from the image and baseline correction was performed using the rubber band method. Further analysis was performed with Malvern ISys version 5.0, concatenating 2x2 adjacent single images in the x-direction and three replicates of different samples in the y-direction. The silicone distribution was measured at 1259 cm -1 Si-CH3 and 2921cm -1 It is calculated using the peak ratio between CH2 and

[0112] Instron Friction Method (IFM) IFM (Instron Friction Method TMD01645 IFM-1) is used to determine surface friction on dry hair switches after treatment with shampoo / rinse-off conditioner / leave-on treatment (LOT). The objective is to assess the smoothness of the hair surface. Lower friction values ​​indicate a smoother hair surface. Values ​​below 70 are considered relatively smooth.

[0113] Pendulum free flow method A pendulum (TMD01646 Pendulum Free Flow Method II) is used to determine the force applied by swinging a dry hair switch after treatment with shampoo / rinse-off conditioner / LOT. The objective is to evaluate the free flow of hair in a pendulum motion. A higher measurement result indicates a better free flow effect of the hair. A value higher than 1 is considered relatively free flow.

[0114] Silicone adhesion Total silicones on the hair are extracted using an organic solvent, hexane:isopropyl alcohol (1:1 ratio). The silicones extracted from the hair are measured using Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). This technique measures silicon as an element contained in the silicone polymer. Quantitative analysis of Si by ICP-AES is performed at 251.432 nm.

[0115] Fatty alcohol adhesion Cetyl and stearyl alcohols on hair are extracted from hair switches with hexane:isopropyl alcohol (1:1 ratio) containing 1-nonadecanol as an internal standard. The sample extract is then injected into a gas chromatograph equipped with flame ionization detection (FID) for quantification, and the amounts of cetyl and stearyl alcohols are summed and calculated as total fatty alcohols.

[0116] Cationic surfactant adhesion Cationic surfactants such as behentrimonium methosulfate (BTMS) were extracted from the hair switches with hexane:isopropyl alcohol (1:1 ratio) and analyzed using high-performance liquid chromatography (HPLC) equipped with a strong cation exchange column, followed by detection by an evaporative light scattering detector (ELSD).

[0117] Scanning Electron Microscopy (SEM) SEM micrographs were obtained with a Zeiss Crossbeam 540 scanning electron microscope operating at 10 kV accelerating voltage using a secondary electron detector and an energy-dispersive X-ray microanalysis system (Bruker). Small pieces of hair strands (1 cm long) were cut from the center of the hair switches, mounted on copper sample holders using conductive double-sided adhesive carbon tape, and then sputter-coated with a thin layer of platinum-palladium at room temperature in a Quorum PP3010 preparation chamber to ensure their electrical conductivity. Five strands per hair switch were analyzed at 2000x and 5000x magnification for surface morphology and Si elemental maps reflecting silicone distribution.

[0118] Test results IR microimaging results Figure 1 shows microscopic observations of silicone distribution in three conditioners. The microscope image of the conditioner containing only pure silicone has a distinct silicone edge (Comparative Example 4), while the image of the conditioner containing only nanoemulsion Si has a more uniformly distributed silicone cloud without a distinct droplet boundary (Comparative Example 5). When the nanoemulsion and pure silicone are blended, the edges of the silicone droplets become blurred and the silicone signal is "diluted" (Inventive Example 1). This "clouding" effect on the pure silicone oil droplets is believed to reduce excess deposition and improve hair free flow. This indicates some synergistic interaction between the nanoemulsion and silicone oil, resulting in a lightweight yet conditioning effect.

[0119] IFM and pendulum free flow results Full performance data is included in Table 2. IFM results indicate the smoothness of the hair surface, and pendulum results indicate the free-flow properties of the hair. We found that products that provide both low IFM and high pendulum results perform well. A conditioner made using only Waro Y20875 nanoemulsion (Comparative Example 5) has a high pendulum result with very good free-flow properties, but its high IFM result indicates that the hair surface is not sufficiently smooth. In contrast, a conditioner made using only pure silicone oil (Comparative Example 4) has a low IFM result, but its pendulum result is also low, indicating that the hair is smooth but not free-flowing. Surprisingly, conditioners made using a blend of Waro Y20875 and silicone oil meet both favorable boundary conditions (Inventive Examples 1 and 2). Not only is the free-flow effect significantly enhanced, but the smoothness of the hair surface is also largely preserved. This indicates that the blend of silicone nanoemulsion and pure silicone oil modifies the hair surface without depositing much on the hair.

[0120] [Table 2]

[0121] The inventors have found that products with IFM results below 70 are relatively smooth and pendulum results above 1 are relatively free flowing. Using the preferred performance ranges and results from both the inventive and comparative examples, the inventors have calculated preferred blend ratios based on interpolation, as shown in Table 3.

[0122] [Table 3]

[0123] Therefore, as the nano-sized silicone to pure silicone ratio decreases below 37:63, the 5-cycle pendulum value decreases below 1, indicating that there is a limit to the blend ratio for free-flow effect. Similarly, as the nano-sized silicone to pure silicone ratio increases beyond 73:27, the 5-cycle IFM result increases above 70, beyond which the hair surface is considered less smooth.

[0124] Additionally, the conditioner made with a blend of ADM8100E nanoemulsion (Comparative Example 6) was smooth but not free-flowing, indicating that not all nanoemulsions blended with pure silicone oils work to achieve both benefits. The silicone contained within ADM8100E is not a polyquaternium silicone.

[0125] To understand the performance effects, deposition tests were conducted on silicone, fatty alcohol, and cationic surfactant. The silicone deposition data in Table 4 for Inventive Example 1 and Comparative Examples 4, 5, and 6 demonstrate why blending Waro Y20875 nanoemulsion with silicone oil still provides a free-flow effect. The amount of deposition was significantly reduced from the conditioner containing pure silicone oil and did not accumulate over multiple wash cycles, as with pure silicone oil. This also explains why the conditioner containing ADM8100E did not improve free-flow properties. The amount of silicone deposition was enormous, indicating that nano-sized silicone properties were the problem.

[0126] Interestingly, the same effect was observed for the deposition of fatty alcohol and cationic surfactant. The deposition of FaOH and quaternary surfactant for Inventive Example 1 (a blend of Waro Y20875 and pure TAS) was significantly reduced from Comparative Example 4 (pure TAS alone) and comparable to the use of nanoemulsion silicone alone (Comparative Example 5). On the other hand, the blend of ADM8100E and pure TAS (Comparative Example 6) showed enormous deposition and accumulation over multiple cycles for both fatty alcohol and quaternary surfactant.

[0127] [Table 4]

[0128] SEM images of hair treated with the example formulations are shown in Figure 2. Except for the blank hair image, all hair surfaces are treated with the example formulations for 5 cycles. For Waro Y20875 (Comparative Example 5) and its blend with pure silicone oil (Inventive Example 1), the hair cuticle is clear and no obvious material deposits can be observed, whereas for the hair surfaces treated with pure silicone oil (Comparative Example 4) and ADM8100E (Comparative Example 6), a thick deposit layer can be observed on the hair strand.
