Abstract

A continuous system for manufacturing a composition that contains an active ingredient that includes a base manufacturing portion and an addition portion. The system can manufacture compositions having different levels of the active ingredient. A base is formed that contains a first level of the active ingredient that is desired for any composition to be manufactured. The addition portion can be used to add more of the materials for the composition to lower the level of the active ingredient, or more active ingredient can be added to increase the level of the active ingredient. The system is controlled by a sensor that measures an amount of associated material that is associated with the active ingredient. This is useful when the active ingredient is not detectable by the sensor.

First claim

What is claimed is:

1. A continuous system for manufacturing at least two compositions containing at least one active ingredient, wherein the continuous system can manufacture the at least two compositions having a different level of the active ingredient comprising:
a) a base manufacturing portion of the continuous system for mixing the active ingredient with at least one additional material to make a first base composition,
b) an addition portion of the continuous system after the base manufacturing portion of the continuous system to form at least one second base composition by adding,
i) the at least one additional material to form the at least one second base having a lower level of the active ingredient,
ii) the active ingredient to form a second base having a higher level of the active ingredient, or
iii) more of the active ingredient and the at least one material that formed the first base to produce more of the first base, and

c) a near-infrared sensor for controlling the system and an amount of active ingredient in the at least one second base composition, wherein the sensor measures an amount of an associated material that is associated with the active ingredient, wherein the sensor cannot detect the active ingredient, and wherein the active ingredient is inorganic, and the associated material is organic.

2. The continuous system of claim 1 , wherein the continuous system is split into at least two streams after the base manufacturing portion, and the addition portion is present on at least one of the at least two streams.

3. The continuous system of claim 1 further comprising an additive system.

4. The continuous system of claim 3 , wherein the additive system is after the addition portion.

5. The continuous system of claim 1 further comprising an inline mixer after the addition portion.

6. The continuous system of claim 1 , wherein the active ingredient comprises an antiperspirant comprising an aluminum containing salt.

7. The continuous system of claim 1 , wherein the associated material is at least one material chosen from an amino acid, glycine, trimethylglycine, polyethylene glycol, and propylene glycol.

8. The continuous system of claim 1 , wherein the associated material is not an additional material.

9. A process for operating the continuous system of claim 1 for controlling the amount of active ingredient comprising:
a) forming the first base composition in the base manufacturing portion of the continuous system comprising mixing the active ingredient with the at least one additional material for the first base composition,
b) adding to the first base composition through the addition portion
i) at least one of the additional materials to form the at least one second base having a lower level of the active ingredient,
ii) the active ingredient to form a second base having a higher level of the active ingredient, or
iii) more materials that formed the first base to produce more of the first base, and

c) controlling the continuous system by measuring the amount of the associated material with the sensor and adjusting the composition until a desired level of active ingredient is obtained.

10. The process of claim 9 , wherein the adding to the first base composition through the addition portion comprises the at least one of the additional materials to form a second base having a lower level of the active ingredient.

11. The process of claim 10 , wherein the second base is diluted with all of the additional materials that are included in the first base.

12. The process of claim 11 , wherein the additional materials added to the second base are in the same proportion to each other as are added to the first base.

13. The process of claim 9 , wherein the adding to the first base composition through the addition portion comprises the active ingredient to form a second base having a higher level of the active ingredient.

14. The process of claim 9 , wherein the only difference between the first base composition and the second base composition is the level of the active ingredient.

15. The process of claim 9 , wherein the adding to the first base composition through the addition portion comprises the more materials that formed the first base composition to produce more of the first base composition.

16. The process of claim 9 , wherein the compositions are antiperspirant compositions, and the active ingredient is an antiperspirant.

17. The process of claim 16 , wherein the antiperspirant is present in the first base composition in a maximum amount that does not require a prescription for use.

18. The process of claim 9 , wherein the continuous system further comprises an additive system, and the process further comprises adding an additive material to the composition through the additive system.
