ASSESSMENT OF THE SPREADABILITY OF OFFICIAL PHARMACEUTICAL CREAMS AND OINTMENTS USING THE MASTER CURVE CONCEPT

Abstract . Spreadability characteristics of official creams and ointments of the British Pharmacopoeia and the British Pharmaceutical Codex were determined using the Master Curve concept and continuous shear data. Experimental results were obtained using a Ferranti-Shirley cone and plate viscometer at 25 C and 34 C, representing an approximate temperature range encountered during spreading of topical preparations. Data derived for creams intersected the Master Curve in the preferred region, although not at the optimum value. Ointments demonstrated large variations in spreading properties. The variation and lack of optimum spreadability characteristics were explained by considering the medicinal criteria required of topical pharmaceutical products as distinct from cosmetics.

41—THE DETERMINATION OF THE YIELD POINT FROM AN AVERAGE LOAD–ELONGATION CURVE FOR A LARGE NUMBER OF FIBRES

A method is described for obtaining an average load–elongation curve from tests on about 100 similar fibres. The average curve is used to obtain a value for the specific work of rupture and the yield point of the fibre sample. The latter is obtained from the third derivative of the average curve, and a comparison is made between the yield point so obtained and that given by the method of Meredith.     

23—A THEORETICAL ANALYSIS OF THE TENSILE PROPERTIES OF PLAIN-KNITTED FABRICS. PART I: THE LOAD-EXTENSION CURVE FOR FABRIC EXTENSION PARALLEL TO THE COURSES

An investigation is described in which, by means of a two-dimensional model of the plain-knitted structure, load-extension curves for extension in the course direction were calculated theoretically. It was assumed initially that the only mechanism of fabric extension was elastic deformation of the loop shape. Account was taken of setting of the yarns into the relaxed-loop shape, but this was found not to have any significant effect on the theoretical load–extension curves. It was found that the intial portions of these curves were almost linear but that the slope could be greatly affected by the occurrence of lateral yarn compression. When yarn compression was taken into account, good agreement was obtained with experimental results for a nylon-monofilament fabric and a series of wool plain-knitted fabrics.     

38—A NEW METHOD FOR DETERMINING THE VARIANCE–LENGTH CURVE OF YARNS AND SLIVERS

A method is described for the determination of a large number of points on the variance–length curve with a high degree of accuracy and in a reasonably short period of time. A capacitance-type irregularity tester is employed, together with data-logging equipment for transferring details of strand linear density onto punched paper tape. Points on the variance–length curve can then be calculated by feeding this tape directly into a digital computer.     

FAST FOURIER TRANSFORMATION ANALYSIS OF THE FORCE-DISPLACEMENT CURVE AS A TEXTURE METHOD RELATED TO FRUIT MORPHOLOGY1

A method is proposed to quantify localized food texture by cutting through a cylindrical sample with a wire probe in an Instron universal testing machine. For probe wire diameters of 0.10, 0.63, 0.80, and 1.23 mm, finer wire was more sensitive to force changes for the fruit tested but required a preload tension and may not be strong enough for harder materials. A frequency analysis (FFT) was performed on the force-displacement curves generated as the wire penetrated the sample. FFT peak energies were found at frequencies below 4 Hz for both a standard material and fruit. The first energy peak was the narrowest for a nonbiological material and widest for apples and pears. Peaches stored 28 days had three times more FFT energy in the lowest frequency band.     

COMPLEX VISCOSITY-TEMPERATURE MASTER CURVE OF CORNSTARCH DISPERSION DURING GELATINIZATION

Complex viscosity (η*) of 8% cornstarch dispersion during gelatinization at oscillatory frequencies (ω): 0.63–47.12 (rad s^?1) was independent of the heating rates: 1.6–6.0 (°C min^?1) when temperature was the independent variable. The influence of ω on η* was scaled by a frequency shift factor resulting in reduced complex viscosity (η*_R) versus temperature (60–95C) master curve. Similar η*_R master curves were derived for data on 6% and 3.5% dispersions. A modified Cox-Merz rule correlated the complex and apparent viscosity data, and a power law model described the effect of concentration of the gelatinized structures.
