Abstract

A method of determining the viability of a gum for use in making a product has been achieved by (a) mixing a sample of the gum in a solvent comprising one or more hydroxy moiety containing solvent compound to form a solution with the gum; (b) measuring the viscosity of the solution and comparing against a predetermined target viscosity for a product; and (c) comparing the viscosity of the solution and the predetermined target viscosity and discarding gum which is outside the predetermined target viscosity; and (d) using the gum which has a viscosity within the predetermined target to prepare a product; wherein another hydroxy moiety containing solvent is used if water is used as a solvent. Also described are compositions comprising the gum and solvent comprising one or more hydroxy moiety.

Description

[0001 ] Gums (also known as hydrocolloids) are well known thickening agents, gelling agents and binding agents and have also been used as emulsifiers, foaming or whipping agents, encapsulating agents, film forming agents, flocculating or clarifying agents and crystallization, inhibitors. See Carbohydrates in Food, ed. Ann-Charlotte Eliasson, pg. 285 (1996); see also Food Chemistry, ed. Owen Fennema, pg. 186-190 (1996).

[0002] Given their widespread utility, the gums are often consumed in vast quantities in industry. A problem associated with the use of gums is how to quickly ascertain a bad lot or batch of gum material provided by a bulk manufacturer of gums. Far too often, the unsuitability of the gum material is not detected until after the final product has been produced.

[0003] Complicating this problem is that feedstock for gums from natural origin are often the source of attribution to account for different viscosity patterns for gums received from different suppliers. Moreover, in order to obtain specific viscosity properties for their gums, suppliers often rely on proprietary mixing techniques to form their products.

[0004] Given the stringent regulatory laws and rules governing pharmaceutical and food compositions, it would be beneficial to detect any potential problems with a gum purchased from a supplier as early in the process of making a product as possible.

[0005] The comparison of viscosities are especially critical when using different, suppliers or changing suppliers of the thickener or emulsion stabilizer compounds.

[0006] A common method of testing a gum sample is the use of gel permeation chromatography (GPC) with or without a size exclusion chromatography (SEC) system. A test sample is injected into the chromatographic system and the properties of the gum are determined via a detector system comprised of one or more of a refractive index detector and a viscometer.

[0007] The viscometric data generated can form a Mark-Houwink plot, the curvature of which can provide information about properties of the tested gum material,

[0ΘΘ8] However, the GPC/SEC system, in addition to being time consuming, suffers from needing expensive and sensitive equipment more suited for the small scale, controlled environment of a university laboratory rather the rigorous conditions of a factoiy floor. [0009] Other methods for determining viscosity and the homogeneity of a gum include a rheologieal method (creep and recovery test) and the use of NIR (near infrared) spectroscopy, [0010] The creep and recovery test, a sample reacts to constant shear stress for a certain period of time by deforming ("creep"). The sample is then relieved of the shear stress so that it can recover. See ASTM-D2990 (creep test); ASTM-D2991 (stress relaxation test)

[0011] However, this method also suffers from the problems of requiring high-cost test equipment (rheometer) and being a lengthy test process when measuring the time from sample preparation to final analysis of the tested sample.

[0012] The use of NIR spectroscopy also requires high-cost test equipment and its accuracy in determining viscosity, and therefore, the homogeneity of the gum, is uncertain.

[0013] Water has also been used with gums for the purposes of viscosity assessment by forming a slurry, dispersion or solution of the gum in water. However, this form of the gum often leads to incomplete dispersion or solubilization of the gum in water and to the formation of lumps which skews the viscosity measurements.

[0014] In addition, formation of such slurries, dispersion or solutions in water may require 24-48 hours for the gum to swell and impart its optimum viscosity.

[0015] Therefore, a need still exists in the art to quickly and accurately determine the viability of using a gum.

BRIEF SUMM ARY

[0016] A method of determining the viability of a gum for use in making a product has been ach iev ed by (a) mi xing a sampl e of the gum in a solv ent comprising one or more hydroxy moiety containing solvent compound to form a solution containing the gum; (b) measuring the viscosity of the solution and comparing against a predetermined target viscosity for a product; and (c) comparing the viscosity of the solution and the predetermined target viscosity and discarding gum which is outside the predetermined target viscosity; and (d) using the gum which has a viscosity within the predetermined target to prepare a product; wherein another hydroxy moiety containing solvent is used if water is used as a solvent.

EXAMPLES

Example 1 - Preparation of 3% CMC sample solution in water and glycerin

[0054] Equipment - Viscometer: Brookflekl Model RVDV-II+ equipped with Helipath Stand and T-Bar Spindle T-C; Overhead Stirrer: IKA Model Eurostar power control - vise equipped with two-bladed centrifugal stirrer or four bladed propeller stirrer.

[0055] In a 600 ml, beaker, 242.50 g of glycerin (A) was weighed. In a separate container, 242.50 g of water (B) was weighed. In a separate container, 15.00 g sample of sodium CMC (C) was weighed. Using the overhead stirrer, glycerin (A) was agitated at 1000 rpm. Sodium CMC (C) was added to the glycerin (A) under agitation at 1000 rpm and allowed to mix for 5 minutes. Water (B) is added to the mixture of (A) + (B) under agitation at 1000 rpm. The mixing speed is then raised to 2000 rpm and the agitation of the mixture of (A) + (B) + (C) continues for 15 minutes. The container containing the mixture of (A) + (B) + (C) is covered with plastic film and placed in a 25°C temperature controlled environment until further use. Example 2 - Measurement of viscosity after 1 hour and 24 hours

[0056] One hour after the preparation of the 3% CMC sample solution of Example 1, the viscometer is set to spindle type S93 (T-C), a 1 minute stop time and a speed of 2 rpm. The spindle (T-C) is inserted in to the 3% CMC sample solution using the disengaging lever of the Helipath stand.

[0Θ57] The spindle shaft is entirely immersed in the test sample and the reversing rod of the helipath is fully pressed down. The helipath stand is turned on and measurement is started with the viscometer. The viscosity in cP and % torque is recorded upon completion of the measurement.

[0058] The measurement steps described above is repeated by inserting the spindle at a different point of the 3% CMC sample solution. The average between the first and second readings is recorded as the final viscosity result. The 3% CMC sample solution is covered with plastic film and placed in a 25°C temperature controlled environment until further use.

[0059] 24 hours after the preparation of the 3% CMC sample solution of Example 1, viscosity is measured by repeating the steps described above for one hour after preparation.

Example 3 - Comparison of CMC lots with known CMC lots with unacceptable viscosity

[0060] 3% CMC sample solution from CMC lot #50011 (high viscosity) and CMC lot #67109 (low viscosity) were measured for viscosity against 3% CMC sample solution from different CMC lots (#149911 and #146811) using the methods described in Example 2. The results of these measurements is presented in Table 1 below.

[0061] Table 1

[0062] Toothpastes prepared with CMC from Lot # 5001 1 and # 67109 had unacceptable viscosities especially when compared with toothpastes prepared with CMC from Lot # 149911 and Lot # 146811, which presented an expected viscosity behavior.

Example 4 - Comparison of CMC lots with known CMC lots with unacceptable viscosity [0063] 4% CMC sample solution from CMC lot #5001 1 (high viscosity) and CMC lot #67109 (low viscosity) were measured for viscosity against 4% CMC sample solution from different CMC lots (#14991 1 and #146811) using the methods described in Example 2. The 4% CMC sample solutions were prepared by using the methods described in Example 1 and increasing the amount of CMC sample taken. The results of these measurements is presented in Table 2 below.

[0064] Table 2

[0065] Toothpastes prepared with CMC from Lot # 50011 and # 67109 had unacceptable viscosities for consumer use especially when compared with toothpastes prepared with CMC from Lot # 149911, 146811, 18981 1, 12601 1 and 10151 1.

Example 5 - Preparation of CM C sample in polyethylene glycol (PEG 600)

[0Θ66] A silica based dentifrice was prepared which had the formula outlined in Table 3 below:

Table 3

[0067] During the manufacturing process of this dentifrice, the carboxymethyiceliulose supplied by Supplier #1 resulted in a dentifrice product density of about 13 bku on average initially (bku = British kinetic unit; 1 bku x 10,000 = cps). The same dentifrice product was made with carboxymethyiceliulose supplied by Supplier #2 resulted in a dentifrice product density of 18.55 bku initially (see Table 4 below)

Table 4 (viscosity of dentifrice in bku)

[0068] As can be seen in Table 4, the gums used in the process of making the dentifrice resulted in vastly different dentifrice properties despite being formed with ostensibly the same compound, i.e. carboxymethyiceliulose (CMC). Although, the data shows that viscosity buildup was worse for the Supplier #1 product both initially and over seven days relative to the Supplier #2 product, it would have still been beneficial to see a more immediate indicator that the Supplier #1 lot should not have been used in the formation of the dentifrice.

[0069] V arious components of the dentifrice were combined with the C MC and the combination of CMC with PEG 600 resulted in a clear distinction between the CMC used.

Table 5 (40 wt % CMC in PEG 600)

[0070] As can be seen from the data in Table 5, the use of PEG 600 provided an instantaneous distinction between the CMC lots provided by Supplier #2 and Supplier #1.

[0071 J Similar tests were run for two different suppliers of CMC

Table 6 (30 wt % CMC in PEG 600)

[0072] As can be seen from the data in Table 6, the viscosities of the different products were within 12.1% of each other which could make them suitable for interchangeable use in the production of a dentifrice product assuming a permissible variance in viscosity of ± 25%.

Example 6 - Preparation of carrageenan sample in polyethylene glycol (PEG 600)

[0073] The test method from Example 5 as exemplified by the data in Table 5 was repeated except that carrageenan was used as the gum instead of CMC.

Table 7 (40 wt % carrageenan in PEG 600)

[0074] As can be seen from the data in Table 6, the viscosities of the different products are suitable for interchangeable use in the production of a dentifrice product assuming a permissible variance in viscosity of ± 25%. [0075] As those skilled in the art will appreciate, numerous changes and modifications may be made to the embodiments described herein without departing from the spirit of the invention. It is intended that all such variations fall within the scope of the appended claims.
