Description

FLUIDIFIED SUSPENSIONS OF CAISONIC POLYSARACTIC POLYMERS IN EMOLLIENTS AND USE OF THEM FOR THE PREPARATION OF COMPOSITIONS FOR PERSONAL CARE FIELD OF THE INVENTION. This invention relates to fluidized suspensions of polymers of cationic polysaccharides and their use in the preparation of personal care compositions, particularly hair care and skin care compositions. BACKGROUND OF THE INVENTION Cationic polysaccharides have been employed in a many personal care applications, eg, shampoos, bath gels, hair compositions, creams and skin lotions, where they offer rheological properties to desirable compositions and properties. hair and the skin. Emollients are lipophilic materials that are used to soften and lubricate the skin. They are frequently incorporated into cosmetic products to act as lubricants, reduce desquamation and to improve the appearance of the skin. In most cases, the cationic polysaccharides employed in personal care compositions are used in the form of dry powders. However, the handling of dust is often accompanied by the dispersion of particles, which can cause health and safety problems. In addition, in the case of cationic polysaccharides, the problem of particle dispersion is especially complicated since the cationic material tends to adhere strongly to anionic surfaces. In addition, particulate polysaccharides have a tendency to excessive clumping when water is added resulting in low levels of solution, and special attention must be paid when adding these materials to the water to avoid the formation of lumps and gel. Frequently, unacceptable levels of gel remain in these solutions. For these reasons, there is a desire to develop liquid cationic polysaccharide products readily dispersible in aqueous medium, by dispersing them in liquids with which they can be mixed but which are useful in particular personal care applications. Since emollients are widely employed in personal care applications, there is a particular advantage if fluidized suspensions of polymers of cationic polysaccharides in emollients are available. US Patent No. 4,312,675 discloses high concentration polymer pastes containing up to 65% by weight of xanthan gum in a hydrophobic solvent base treated with suspending agents, dispersants and thinning agents. As solvents, mineral oil, diesel oil, kerosene, alcohols (C6-C_2), vegetable oil, ester alcohols, polyol ethers and the like are used. US Patent No. 4,566,977 focuses on an improved non-aqueous paste comprising a water-soluble cellulose ether, a water-insoluble liquid hydrocarbon, a non-ionic surfactant having an HLB of about 7 to about 14, and a modified clay with organ. The water soluble cellulose ethers are selected from anionic and nonionic cellulose ethers. U.S. Patent No. 5,096,490 presents a fluid suspension of 35 to 55 parts of carboxymethylcellulose or a similar polymer in 40 to 55 parts of fatty acid with 1 to 5 parts of clay and up to 20 parts of emulsifier. Guar and hydroxypropyl guar are included in the polymers presented. None of these patents present fluidized suspensions of polymers of cationic polysaccharides nor their use for the preparation of personal care compositions. The solvation and solubility properties of various water-soluble saccharides can vary widely. Accordingly, information on fluidized suspensions of polymers of anionic and nonionic polysaccharides is of little use in predicting which systems will be suitable for preparing fluidized suspensions of polymers of cationic polysaccharides.

SUMMARY OF THE INVENTION In one embodiment of the invention, a fluidized polymer suspension comprises: a) a cationic polysaccharide, b) a stabilizing agent, c) an emollient that is not a solvent for the cationic polysaccharide. In another embodiment of the invention, a method for the preparation of a personal care composition comprises: a) providing a fluidized composition of polymers comprising I) cationic polysaccharide, ii) stabilizing agent, and iii) emollient which is not a solvent for the cationic polysaccharide; and b) mixing the fluidized polymer suspension with one or more active personal care ingredients. DETAILED DESCRIPTION OF THE INVENTION It is characteristic of the fluidized polymer suspensions of this invention that they are stable in the state in which they are made. By the term "stable in the state in which they are made" we understand that the suspension does not separate immediately into two or more different layers when it is in a resting condition. In some cases, when the suspension is used within a short period of time, it is sufficient that the suspensions are moderately stable, ie at least sufficiently stable in such a way that the cationic polysaccharide remains dispersed or can easily be dispersed again after a short period of time of rest. However, dispersed cationic polysaccharides tend to agglomerate, upon settling, in gels or solids that can not easily be dispersed again after a few days' rest (or in some cases much shorter time periods). Accordingly, it is frequently preferred that the suspensions have storage stability for much longer periods of time, since they will be employed - often in applications in which they must be stored for periods of time from about 1 to six months. The fluidized suspensions of polymers of this invention are stable in the state in which they are produced, preferably stable for at least about a week, more preferably stable for at least about 8 weeks, and preferably even more stable for at least about 6 weeks. months Cationic polysaccharides for use in the present invention include any natural cationic polysaccharide, as well as polysaccharides and polysaccharide derivatives that have been cationized by chemical means, for example, quaternization with quaternary amine compounds containing reactive chloride or epoxide sites.

Methods for making various personal care compositions employing fluidized suspensions of polymers containing cationic polysaccharides are described in the following examples which are presented by way of example only and are not intended to limit the invention. All percentages, parts, etc., are by weight unless otherwise indicated.

EXAMPLE 1 This example describes the preparation of a fluidized suspension of polymers of cationic guar in polybutene. Fifty (50) parts of polybutene (Indopol®N-14, from Oco Chemical Co., Chicago, IL), were added to a mixing vessel, and then 2 parts of T een®80 (polyoxyethylene sorbitan acid ester of Ruger Inc., Irvington, NJ) were added and mixed. An amount of 2 parts Claytone® 40 clay (from Southern Clay Products, Gonzales, TX) was added to the mixing vessel, and the resulting mixture was stirred to disperse the clay. After complete mixing of the clay, 45 parts of cathonic guar N-Hance®GPX-3196 (available from Hercules Incorporated, Wilmington, DE) was added and stirred with high shear mixing for dispersion. Finally, 1 part of water was added to the mixture and stirred to disperse. The resulting product showed a fluid state and could be emptied and it was found that it retained its homogeneity without noticeable settlement for a period greater than 30 days. By adding water, the fluidized suspension of polymers produced a rapid increase in viscosity. EXAMPLE 2 This example describes the preparation of a fluidized suspension of cationic hydroxypropyl guar polymer in propylene glycol dicaprylate / dicaprate.

Two (2) parts of silica (Aerosil®200, available from Degussa AG, Hanau, Germany) were added to 68 parts of propylene glycol dicaprylate / dicaprate (Miglyol®840, available from Huels AG, Germany). The mixture was stirred using a moderate shear stress and after dispersion of the silica, 30 parts of cationic hydroxypropyl guar (N-Hance® Cationic HPGuar, available from Hercules Incorporated, Wilmington, DE) was added. After stirring, a fluidized suspension of polymers with a viscosity of 3,800 cps (spindle # 4 of LVT, 30 rpm) was obtained. The suspension was stable for at least one day. EXAMPLE 3 This example describes the preparation of a fluidized suspension of cationic guar polymers in mineral oil. Clay Tixogel®MPl00 (from United Catalyst Inc., Louisville, KY), 3.4 parts, was added to 48.2 parts of a white mineral oil (Marcol®52 CX from Exxon Company, Houston, TX) with agitation under high shear. A complete dispersion and swelling of the clay was achieved at temperatures within a range of 40 to 45 ° C. Then 0.37 parts of sorbitan ester trioleate (Montane®85 from Seppic, Paris, France) and 3.03 parts of ethoxylated sorbitan ester trioleate (Montanox®85 from Seppic) were added (other combinations of surfactants can be used in such a way that it achieves a hydrophilic / lipophilic balance (HLB) of approximately 10). Since the surfactants reduced the viscosity of the mixture, the shear rate was decreased before its addition. After obtaining a completely homogeneous mixture, 45 parts of cationic guar (N-Hance®3000 from Hercules Incorporated, Wilmington, DE) was added with vigorous stirring. The resulting fluidized suspension of polymers had a viscosity of 2,500 cps. After 24 hours, the viscosity was 3,020 cps, after 1 week, 3,480 cps, after 1 month, 5,000 cps and after 4 months 5,000. To measure the syneresis of the fluidized suspension of polymers, glass jars were filled at a height of 50 mm with a fluidized suspension of polymers and then stored at room temperature and at 40 ° C. The height of the clear syneresis layer, if any, was measured. The results are expressed as: syneresis height (mm) / original height (50 mm). For example, "0.5 / 50" means a syneresis of 0.5 mm, original height of 50 mm. The term "film" refers to a thin clear layer too small to be measured. The syneresis results are shown in Table 1. Table 1 Storage time and syneresis temperature 24 hours at room temperature 0 24 Loras at 40 ° C 0 1 week at room temperature 0 1 week at 40 ° C 0 1 month at room temperature pe 1 month at 40 ° C 0. 5/50 4 months at room temperature 2/50 4 months at 40 ° C 6/50 To evaluate the rate at which the cationic guar contained in the fluidized polymer suspension dissolved in water, a fluidized polymer suspension was added to the water in an amount sufficient to provide a 2% solution of cationic guar in water.

As a control, a similar solution was prepared using the same cationic guar powder, used to prepare the fluidized suspension of polymers. In both cases, the pH was adjusted to less than 7 and the mixtures were stirred. The solution time for the dry powder was 30 minutes, and for the fluidized suspension of polymers of only 12 minutes. EXAMPLE 4 This example describes the preparation of a conditioning shampoo formulation employing the fluidized polymer suspension of example 3. For comparison, the same formulation was prepared using the same cationic guar, but in the form of dry powder. The formulation is presented in Table 2. TABLE 2 INGREDIENT PARTS BY CIEN Ammonium lauryl sulfate 30 Cocamidopropyl betaine 12 Propylene glycol 5 Glycol stearate 2 Hydrolysed collagen 2 cocamide DEA 1 Water 47.7 Cationic guar N-Hance®3000 0.3 The cationic guar, already either as a fluidized suspension of polymers or a dry powder, it was added as the last ingredient. When the fluidized suspension of polymers was employed, an amount sufficient to provide the indicated cationic guar level was added. Hydration of the cationic guar started only after pH correction at about 5.5 by the addition of citric acid. The viscosities of the formulations were the same regardless of whether they were prepared from the fluidized suspension of polymers or from powder. The polymerized fluid suspension dissolved rapidly without lumping. The appearance of the finished conditioning shampoo was white, pearl color. EXAMPLE 5 This illustrates the preparation of a cream rinse formulation employing the fluidized polymer suspension prepared in Example 3. For comparison, the same formulation was prepared using the same cationic guar, but in the form of a dry powder. The formulation appears in table 3.

Natrosol®250MR from Hercules Incorporated, Wilmington, DE Part A was prepared by dispersing the cathic guar, either in dry powder or fluidized suspension of polymers, in water and by reducing the pH of the aqueous solution at 6-7. When the cationic guar was completely dissolved, hydroxyethylcellulose was added, and the mixture was heated to 75-80 ° C. When everything was completely dissolved, glycerin was added. A part of the water was reserved to dissolve disodium EDTA from part C. In a separate vessel, part B was mixed and heated to a temperature of 75-80 ° C. It was then added with moderate agitation to part A, and the resulting mixture was stirred until it was completely homogeneous and then cooled. When the temperature was below 30 ° C, the ingredients of part C (disodium EDTA as an aqueous solution) were added, and the pH was adjusted to 5.0 with citric acid. The viscosity of the cream rinse was essentially the same regardless of whether it was prepared using the cationic guar as a fluidized polymer suspension or the dry powder. In both dry, the appearance of the formulations was excellent. We do not intend that the examples presented here limit the invention, but on the contrary, they are presented only to illustrate some specific modalities of said invention. Various modifications and variations to the present invention can be made without departing from the scope of the appended claims.
