Description

[0179] There now follows by way of example only a description of the present invention with reference to the accompanying drawings, in which:

[0180] FIG. 1 shows a longitudinal section of an example container of the present invention; and

[0181] FIG. 2 shows the weight of high-pigment formulation droplets when dispensed from a tottle with a dispensing head comprising a circular dispensing orifice of 0.785 mm.sup.2 containing either Formulation 1 (according to the present invention) or a benchmark formulation. The bars represent the range from the mean minus standard deviation to the mean plus standard deviation, with the middle line representing the mean.

EXAMPLES

Example 1

Viscosity Determination

[0182] The viscosity of Formulation 1 (comprising Aqua (Water), Caprylyl methicone, Caprylic/capric triglyceride, PEG-9 dimethicone, Bis-isobutyl PEG/PPG-10/7dimethicone copolymer, Stearalkonium hectorite, Phenoxyethanol, Magnesium sulfate, Aluminum hydroxide, Triethoxycaprylylsilane, Propylene carbonate, Xanthan gum, Methylparaben, PEG/PPG dimethylallylether, Ethylparaben, Tetrasodium EDTA, Tocopherol, CI 77891 (Titanium dioxide), CI 77492 (Iron oxides), CI 77491 (Iron oxides) and CI 77499 (Iron oxides), with a total pigment concentration of 28%) and a benchmark formulation (comprising an ingredient list equivalent to that of Formulation 1 and with a total pigment concentration of 25%) was determined. Viscosity as described in the present application is measured using a Brookfield LVDV-I Prime E viscometer plus Model G Laboratory Stand, equipped with LV Spindle 64. Viscosity measurements were obtained as follows:

[0183] 1. Ensure the sample product has a temperature of 23° C. and that it is not aerated. Sample is presented in a 60 ml capacity plastic container with a diameter of 35 mm and a height of 70 mm;

[0184] 2. Before measurement, auto-zero the viscometer after switching on the unit by following the on-screen instructions with no spindle attached to the viscometer;

[0185] 3. Select the spindle 64;

[0186] 4. Select the revolution speed “12”. This will rotate the spindle at 12 revolutions per minute (rpm);

[0187] 5. Carefully attach the spindle to the lower shaft of the viscometer;

[0188] 6. Lower the spindle into the sample product until the fluid level is at the immersion groove on the spindle shaft by turning the height adjustment knob on the right hand side of the viscometer mounting bracket. Ensure that the spindle is not in contact with the sides or base of the sample container;

[0189] 7. Press the “Timed Option” buttons;

[0190] 8. Use the Up and Down arrows to select the “Timed Stop” option then press “Enter” to confirm;

[0191] 9. Use the Up and Down arrows to select zero minutes, then press “Enter” to confirm;

[0192] 10. Use the Up and Down arrows to select 30 seconds , then press “Enter” to confirm;

[0193] 11. Press the “Motor On/Off” button to begin the measurement;

[0194] 12. The viscometer will display a countdown from 30 seconds, after which it will display the final viscosity measured; and

[0195] 13. Record the viscosity reading.

[0196] Formulation 1 has a viscosity of 26,000 cps. By contrast, the benchmark formulation has a viscosity of 1,250 cps. Thus, Formulation 1 has a much high viscosity that falls within the scope of the present invention, whilst the benchmark formulation does not.

Example 2

Variation in Droplet Weight

[0197] Formulation 1 and the benchmark formulation were sealed within a tottle with a dispensing head comprising a circular dispensing orifice of 0.785 mm.sup.2.

[0198] Twenty droplets of formulation 1 and the benchmark formulation were expelled whilst the tottle was held in a substantially vertical, dispensing-head-down position. The weight of each of these droplets is presented in Table 1 below.

TABLE-US-00001 TABLE 1 Formulation 1 Benchmark 0.0334 0.0216 0.0316 0.0322 0.0352 0.0301 0.0343 0.0301 0.0307 0.0238 0.0383 0.0259 0.0273 0.0254 0.038 0.0258 0.0361 0.0163 0.0361 0.0307 0.0341 0.0277 0.0303 0.0335 0.0365 0.0291 0.0325 0.0285 0.0328 0.0326 0.0326 0.0267 0.0353 0.0296 0.0329 0.0273 0.0396 0.0250 0.0303 0.0194 Mean 0.0339 0.0271 Standard 0.0030 0.0043 Deviation

[0199] Table 1 and FIG. 2 show that a much more consistent droplet size is seen when a formulation according to the present invention is used. In particular, a decrease in the droplet weight standard deviation by more than a quarter is seen in Formulation 1 when compared to the Benchmark formulation. The increased variation of droplet size seen in the benchmark composition is a result of the tottle of the benchmark composition having an increased tendency to sporadically expel an unusually small quantity of formulation in one droplet. The sporadic release of such small droplets is undesirable as it is likely to be much less than a user needs.
