Description

FIELD OF THE INVENTION 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 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. 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. U.S. Pat. No. 7,217,752B2 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. U.S. Pat. No. 7,589,051B2 describes the use of cationic oxidized polysaccharide compositions in personal care and household compositions. 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. 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. 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. 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. 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 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
