Abstract

A method of making a personal care composition by providing a first layer and a second layer which each are fluid at elevated temperature; solid at ambient temperature; and visually distinctive from each other; providing the first and second layers in fluid state at an elevated temperature in isolated vessels; separately dispensing the first layer by a first nozzle and the second layer by a second nozzle, while maintaining the elevated temperature, into a same package having a circle plan view shape, wherein the positions of the nozzles, relative to the center of the package, are maintained during dispensing, and wherein the middle point of the nozzles do not coincide with the Z axis running vertically through the center of the package; and cooling the dispensed composition for solidifying in the package.

Claims

1. A method of making a personal care composition comprising the steps of:

(a) providing a first layer and a second layer which each are fluid at elevated temperature;

solid at ambient temperature; and

visually distinctive from each other;

(b) providing the first and second layers in fluid state at an elevated temperature in isolated vessels;

(c) separately dispensing the first layer by a first nozzle and the second layer by a second nozzle, while maintaining the elevated temperature, into a same package having a circle plan view shape;

(d) wherein a middle point of the nozzles does not coincide with a Z-axis running vertically through the center of the package; and

(e) cooling the dispensed composition for solidifying in the package.

2. The method of claim 1, further comprising dispensing a third layer the third layer being fluid at elevated temperature and solid at ambient temperature;

the third layer dispensed from a third nozzle separate from the first and second nozzles while maintaining the elevated temperature;

wherein the first, second, and third nozzles are horizontally aligned, the first nozzle is positioned at the middle point of the second and third nozzles, and the position of the first nozzle does not coincide with the Z-axis running vertically through the center of the package.

3. The method of claim 1, wherein the package is rotated around the Z axis running vertically through the center of the package for at least a portion of period during the dispensing.

4. The method of claim 1, wherein the positions of the nozzles, relative to the center of the package, are maintained during dispensing.

5. The method of claim 1, further comprising dispensing a third layer, the third layer being fluid at elevated temperature and solid at ambient temperature;

the third layer dispensed from a third nozzle separate from the first and second nozzles while maintaining the elevated temperature;

wherein the first, second, and third nozzles are not horizontally aligned.

6. The method of claim 1, wherein the nozzles are physically bundled in a fixed distance relative to each other to form a nozzle block, and wherein the nozzle block is moved along an X-axis running horizontally through the center of the package during at least a portion of the dispensing.

7. The method of claim 1, wherein when the layers have an unequal volume each nozzle flow rate is controlled such that all layers are dispensed at about a same starting and completion time point.

8. The method of claim 1, wherein the layers are solid at 45°

C.

9. The method of claim 1, wherein the elevated temperature is from about 55°

C. to about 90°

C.

10. A method of making a personal care composition comprising:

(a) providing a first layer and a second layer which each are fluid at elevated temperature, solid at ambient temperature, and visually distinctive from each other;

(b) providing the first and second layers in fluid state at an elevated temperature in isolated vessels;

(c) separately dispensing the first layer by a first nozzle and the second layer by a second nozzle into a same package while maintaining the elevated temperature, wherein the package mar be rotated during the dispensing;

(d) wherein at least one of the following steps (i) through (iv) takes place during the dispensing; and

(i) the dispensing of the first and second nozzles are started and/or completed at a different time point;

(ii) the rotation of the package is completed prior to the completion of dispensing;

(iii) the direction of rotation of the package is altered during the dispensing;

(iv) the flow rate of at least one of the first and second layers are altered during dispensing;

(e) cooling the dispensed composition for solidifying in the package.

11. The method of claim 10, wherein the package is rotated around a Z-axis running vertically through the center of the package for at east a portion of period during the dispensing.

12. The method of claim 10, wherein the positions of the nozzles, relative to the center of the package, are maintained during the dispensing.

13. The method of claim 10, further comprising dispensing a third layer, the third layer being fluid at elevated temperature and solid at ambient temperature;

the third layer dispensed from a third nozzle separate from the first and second nozzles while maintaining the elevated temperature;

wherein the first, second, and third nozzles are horizontally aligned, the first nozzle is positioned at the middle point of the second and third nozzles, and the position of the first nozzle coincides with the Z axis running vertically through the center of the package.

14. The method of claim 10, further comprising dispensing a third layer:

the third layer being fluid at elevated temperature and solid at ambient temperature;

the third layer dispensed from a third nozzle separate from the first and second nozzles while maintaining the elevated temperature;

wherein the first, second, and third nozzles are not horizontally aligned.

15. The method of claim 10, wherein each layer has a viscosity of from about 100 mPas to about 3000 mPas when brought to a temperature of between about 55°

C. and about 90°

C.

16. The method of claim 10, wherein the composition is a solid cosmetic composition.

17. The method of claim 16, wherein the layers are water-in-oil emulsions.

18. The method of claim 10 wherein at least one of the layers is different in composition from the other layers other than in visual appearance.

19. A method of making a personal care composition, comprising:

(a) providing a first layer, a second layer and a third layer which each are fluid at elevated temperature, solid at ambient temperature, and visually distinctive from each other;

(b) providing the first, second and third layers in fluid state at an elevated temperature in isolated vessels;

(c) separately dispensing the first layer by a first nozzle, the second layer by a second nozzle, and the third layer by a third nozzle while maintaining the elevated temperature, into a same package having a circle plan view shape;

(d) wherein the first, second, and third nozzles are not horizontally aligned; and

(e) cooling the dispensed composition for solidifying in the package.
