A SUSPENDING POLYMER COMPOSITION, AND METHOD OF USE THEREOF FIELD OF THE INVENTION [0001] The present application relates to a polymer composition, and more particularly, to a suspending polymer composition comprising a blend of: (i) hydroxypropylmethylcellulose (HPMC); (ii) xanthan gum; and (iii) cetyl-hydroxy ethyl cellulose (cetyl-HEC), wherein the composition finds particular utility in personal care and home care compositions. BACKGROUND OF THE INVENTION [0002] Various substantially insoluble compounds cannot be adequately stabilized in aqueous surfactant containing compositions. For example, aqueous surfactant formulations that contain silicone additives, such as personal care and home care composition, tend to isolate from their surfactant base. Conventional polymeric rheology modifiers, such as carbomers and/or acrylates and alkyl acrylate cross polymers have been used to improve viscosity. [0003] There are naturally derived thickening technologies already on the market such as xanthan gum, bentonite, hectorite, cellulose gum and guar. The challenge is that most of the technologies provide only thickening but not suspension performance. The ingredients which suspend can have a negative influence on sensorial benefits (rheology, foam) and silicone deposition. Also, stability is often an issue. Currently no ingredients are meeting all the formulators’ requirements. [0004] US Patent 7217752B2 describes a stable, aqueous composition containing a substantially crosslinked alkali-swellable acrylate copolymer rheology modifier, a surfactant, an alkaline material, and various compounds therein, as for example, substantially insoluble materials requiring suspension or stabilization, such as a silicone, an oily material, or a pearlescent material. [0005] US Patent 7589051B2 describes the use of cationic oxidized polysaccharide compositions in personal care and household compositions. [0006] PCT Application 2019025233A describes cosmetic compositions, especially hair cleaning compositions or hair styling compositions comprising a biobased polymer for improving the appearance and manageability of hair.   [0007] PCT Application 2016154701A describes a hair cosmetic composition comprising a thiol-based compound selected from thiolactic acid and its derivatives or salts, and a thickening agent selected from thickening polymers comprising at least one sugar unit, for instance nonionic guar gums, optionally modified with C1-C6 hydroxyalkyl groups, biopolysaccharide gums of microbial origin, such as scleroglucan gum or xanthan gum, gums derived from plant exudates, such as gum arabic, ghatti gum, karaya gum, gum tragacanth, carrageenan gum, agar gum and carob gum, pectins, alginates, starches, hydroxy (C1-C6) alkylcelluloses (hydroxyalkyl celluloses), and carboxy (C1-C6) alkylcelluloses, and mixtures thereof, and preferably from hydroxyalkyl cellulose, such as hydroxyethylcellulose, hydroxymethylcellulose, methylhydroxyethylcellulose, hydroxypropylcellulose, hydroxybutylcellulose, hydroxyethylmethylcellulose (also known as methyl hydroxyethylcellulose) and hydroxypropylmethylcellulose, cetyl hydroxyethylcellulose, and mixtures thereof. [0008] In view of the foregoing, still there is a need to develop and produce sufficiently stabilized aqueous surfactant-based compositions that can include water-insoluble materials such as silicones, oily materials, pearlescent materials, cationic hair dyes, and other substantially insoluble materials. [0009] Accordingly, it is an objective of the present application to provide a novel suspending system or composition which is free from or substantially free from carbomer/acrylates for personal care or home care applications, wherein said suspending composition can produce sufficiently stabilized aqueous surfactant-based compositions that comprise at least one water insoluble material. Accordingly, the present application provides a unique blend consisting of naturally derived rheology modifiers to provide a performance comparable or even better than existing carbomer or acrylate-based rheology modifiers in surfactant-based personal care and home care applications and systems. [0010] Accordingly, the multifunctional natural based cellulosic/polysaccharide blend described in this application consisting of hydroxypropylmethylcellulose (HPMC), xanthan gum and cetyl hydroxyethylcellulose (cetyl-HMHEC) provides improved properties compared to the existing natural technologies. The blend is salt tolerant, compatible with cationic ingredients and transparent. Further, the blend does not require neutralization and provides excellent suspension of water insoluble ingredients in personal care and home care applications. Moreover, the blend is  

compatible with anionic, cationic and nonionic ingredients, and demonstrates good electrolyte tolerance. SUMMARY OF THE INVENTION [0011] The primary aspect of the present application is to provide a suspending polymer composition free of acrylates and methacrylates comprising a blend of: (i) about 40 to about 80 wt.% of hydroxypropylmethylcellulose (HPMC); (ii) about 10 to about 30 wt.% of xanthan gum; and (iii) about 10 to about 30 wt.% of cetyl-hydroxy ethyl cellulose (cetyl-HEC) particularly for use in aqueous based personal care or home care compositions.

[0085] Further, certain aspects of the present application are illustrated in detail by way of the following examples. The examples are given herein for illustration of the application and are not intended to be limiting thereof. EXAMPLES [0086] Hydroxypropylmethylcellulose (HPMC) or methylhydroxypropylcellulose (MHPC) rheology modifier commercially available from Ashland LLC - Table 1) were evaluated. [0087] Example 1: Hypromellose (HPMC) grades [0088] Example 2: A blend consisting of 65 % hydroxypropylmethylcellulose, 17.5 % Xanthan gum and 17.5 % cetyl-hydroxyethylcellulose was used to suspend water insoluble ingredients in surfactant-based rinse-off systems (Table 2). Water insoluble ingredients in this example are   silicones (dimethiconol) and Mica. Fully formulated shampoo which was used for the studies (Table 3). [0089] The shampoo passed 1 month accelerated stability test at 52.5° C. It was also tested to be stable 3 M at 45° C (industry benchmark test method). Xanthan gum at dose level 0.4 % did not pass the test. Phase A: N-Hance 3196 was dispersed in water & mix until lump free. Citric Acid was added and mixed until fully hydrated. Surfactants were added in the right order of Table 3 formulated shampoo, ingredients were dispersed of phase B in Glycerin and add to phase A. Add the ingredients of Phase C in order with good stirring and adjust Phase D the pH with Sodium Hydroxide (33%) or Citric acid (50 %) and Sodium Chloride to the desired viscosity. The pH was maintained at 5.5 – 6.0 and Viscosity at 5,000 – 9,000 mPa.s Brookfield LVT Spindle #3, 12 RPM, 1min @ 25 °C.  

[0090] It was observed from Fig.1 that to achieve the required suspension stability all 3 ingredients are required (the product on the right). The sample on the left was consisting of a combination of xanthan gum and HPMC and the example in the middle contains a blend of HPMC and HMHEC. These samples are not stable over time. [0091] Example 3: Emulsion stabilization [0092] Hair care conditioners are typically lamellar gel phases having a fixed ratio of cationic surfactants and fatty alcohol. The most widely ratio is 1:3. The most widely used cationic surfactants are Behentrimonium Chloride, Cetrimonium Chrloride and Tertiary amine salts. The typical fatty alcohols could be Cetearyl Alcohol, Cetyl Alcohol and Stearyl Alcohol. The total amount of the lamellar gel ingredients was related to the rheological properties such as viscosity and stability and sensorial properties. Consumer’s perception related to the conditioning performance relates to the texture of the product. The rich texture relates to an assumption of high level of conditioning. For that reason, a typical dose level of cationic surfactants in a lamellar gel conditioner was 2 wt % and fatty alcohol 6 wt %. The high ingredient level though is not influencing on the hair conditioning properties. It is possible to split the amount of lamellar gel and have the same level of conditioning performance. The challenge of the reduced gel phase was related to a thin consistency and instability of the conditioner. [0093] These challenges can be overcome by using an additional polymeric rheology modifier. The lamellar gel phases have a cationic nature and for that reason the anionic rheology modifiers such as acrylates and xanthan gum cannot be used for this application to stabilize the systems. It has been shown that a blend of naturally derived polysaccharides described in this application was compatible with cationic systems and stabilizes systems with a reduced lamellar gel phase. A typical dose level could be 0.1 – 0.6 w-%. In the graph below a dose response behavior is presented (Fig 2). [0094] Example 4: Silicone deposition [0095] Acrylate alkali soluble emulsion chemistries such as Carbomer are widely used in shampoos to suspend conditioning agents such as silicones. One of the reasons for their popularity is related to not having a negative influence on the silicone deposition on hair. HASE chemistries  

such as Acrylates copolymer are also used in shampoos on rinse-off systems due to their superior thickening and suspension properties. They are well known though to prevent the silicone deposition out of the conditioning shampoo to hair. In this example, demonstrated that the silicone deposition of current suspending polymer composition is comparable to the carbomer based systems and superior compared to the acrylates chemistries. It can be also seen that both acrylates copolymer and pure xanthan gum had a negative influence on the silicone deposition (Fig.3 and Fig.4). [0096] Example 5: Preferred foam vs Xanthan Gum [0097] One of the important parameters in the rinse-off systems is the foam. Preferable rheology modifiers don’t have an influence on foam. In this invention the foam properties such as flash foam, foam volume and foam stability of the shampoo containing the natural blend was tested against the same shampoo base with xanthan gum. It is clearly observed from the results that xanthan gum has an influence on the foam type and the stability. That can be related to more difficult to rinse-off shampoos. The natural blend didn’t influence on the foam properties (Fig.5). [0098] It is observed from Fig.6 that xanthan gum has a negative influence on the initial foam reducing the number of bubbles. On the other hand, it makes over time the foam very stable. Too stable foam was indicating a difficult to rinse performance.                         [0099] Example 6: Rinse off conditioners using different levels of stabilizer mix. [00100] Example 7: Three months stability results of rinse-off conditioner [00101] The Example 6 formulations are tested for 3-month stability tests for rinse off conditioner. Three months stability results of a low gel phase conditioner with the natural blend containing of hydroxypropylmethylcellulose (HPMC), cetyl-hydroxyethylcellulose (cetyl-HEC), xanthan gum. Fig.7, Fig.8 and Fig.9 show that the respective formulation containing 0.1%, 0,3% and 0.6% natural blend of hydroxypropylmethylcellulose, cetyl hydroxyethylcellulose, xanthan gum at 5 ^o C, room temperature (RT at 21 ^o C) and 45 ^o C. [00102] Example 8: Three months stability results containing 0.3 and 0.6% formulations [00103] It is observed that, formulation containing 0.1% (Fig 7) is stable at three different temperatures for three months wherein, the formulations containing 0.3 and 0.6% (Fig.8 and Fig. 9) respectively shows similar character in terms of stability. At room temperature, both formulations are stable. Slight decrease in viscosity is observed at lower and higher temperatures after three months. Data show that with addition of 0.1% thickener formulation the rinse-off conditioner was stabilized.   [00104] Example 9: Different Shampoo formulation systems to suspend Mica and silicone (Fig. 1 and Fig.12) [00105] Sample 9 shampoo formulation was stable at low temperature and high temperature for three months as shown in Fig.10 and Fig.11. The shampoo formulation has no negative impact on the sensory, however natural blend is having a positive impact on wet/dry hair combability and hair feel when used in a shampoo application shown in Fig.16 and Fig.17. [00106] Example 10: Suspension of Zinc Pyrithione in anti-dandruff shampoos   [00107] Fully formulated anti-dandruff shampoo which was used for the studies. Zinc Pyrithione was widely used by the personal care industry as an active ingredient in anti-dandruff shampoos. It was suspended in the shampoo by using a suspension agent such as Poly(acrylic acid). Phase A: Disperse the natural blend slowly with good mixing. Sodium hydroxide was added and mix for 30 min. until fully hydrated and the surfactants were added in the right order. Phase B was dispersed until lump free and add to phase A; Phase C ingredients were added in order with good stirring   and adjust Phase D with pH with citric acid or NaOH and sodium chloride to the desired viscosity. The creamy viscous liquid was maintained at 5.5 – 6.5 pH and at 6,000 – 8,000 mPa.s Brookfield LVT Spindle #3, 12 RPM, 1 min @ 25 °C. The formulation containing 0.1% (Fig.13) is stable at three different temperatures for three months wherein, the formulations containing 0.3 and 0.6% respectively shows similar character in terms of stability. Data show that with addition of 0.1% thickener formulation the antidandruff shampoo was stabilized. [00108] Example 11: Suspension of natural oils (Coconut oil and meadow oil) in shampoo applications [00109] Fully formulated silicone free shampoo which was used for the studies. Coconut oil and meadowfoam oil was suspended in the shampoo by using a suspension agent such as Poly(acrylic acid). Phase A: Disperse the natural blend slowly with good mixing. Sodium hydroxide was added and mix for 30 min. until fully hydrated and the surfactants were added in the right order. Phase B was dispersed until lump free and add to phase A; Phase C ingredients were added in order with good stirring and adjust Phase D with pH with citric acid or NaOH and sodium chloride to the desired viscosity. The creamy viscous liquid was maintained at 5.5 – 6.5 pH and at 6,000 – 8,000 mPa.s Brookfield LVT Spindle #3, 12 RPM, 1 min @ 25 °C. The formulation containing 0.1% (Fig 14) is stable at three different temperatures for three months wherein, the formulations   containing 0.3 and 0.6% respectively shows similar character in terms of stability. Data show that with addition of 0.1% thickener formulation the silicon free shampoo suspension of natural oils coconut and meadow oil was stabilized.   - [00110] Example 12: Creamy bodywash formula with suspension of lamellar gel & mica.  [00111] 0.8% Natural blend polymer in a body wash formulation was used to suspend mica and Prolipid 161 lamellar gel. Phase A: Disperse the natural blend slowly with good mixing. Heat to 65C and mix for 30 min. until fully hydrated, and the surfactants were added.
