Aerosol antiperspirant methods
An aerosol antiperspirant product method of manufacture is provided, in which the time between the final milling of an antiperspirant composition and its filling into a spray device is at most 2 hours.
1. A method of making an aerosol antiperspirant product, the method comprising:
combining components to form an antiperspirant composition, said components selected from the group consisting of an antiperspirant active, a carrier, a suspending agent, day activator, and combinations thereof;
milling the composition;
re-milling the composition;
depositing the composition into a spray device at most 2 hours after re-milling of the composition, wherein the viscosity of the composition while being deposited is at least about 2000 cP; and
adding a propellant to the composition in the spray device; wherein the composition does not include cyclopentasiloxane.
2. The method of claim 1 , wherein the method further comprises the step of adding at least one perfume or fragrance.
3. The method of claim 2 , wherein the step of adding a perfume or fragrance is after the milling of the composition and before depositing the composition into a spray device.
4. The method of claim 1 , wherein the composition further comprises silicone gums or skin feel modifiers.
5. The method of claim 1 , wherein the antiperspirant composition is anhydrous.
6. The method of claim 1 , further comprising a step of filtering the composition after milling the composition and before adding a propellant.
7. The method of claim 1 , wherein the composition is deposited into a spray device at most about 1 hour after re-milling the composition.
8. The method of claim 1 , wherein the composition comprises a carrier that is a nonvolatile linear silicone fluid with nine or more average silicone atoms.
9. The method of claim 1 , wherein the viscosity of the antiperspirant composition is at least about 4000 cP.
10. The method of claim 1 , wherein the components of the antiperspirant composition are at least about 500 kilograms.
11. A method of making an aerosol antiperspirant product, the method comprising;
combining components to form an antiperspirant composition, said components selected from the group consisting of an antiperspirant active, a carrier, a suspending agent, a clay activator, and combinations thereof, and said antiperspirant composition not comprising cyclopentasiloxane;
milling the composition;
re-milling the composition;
depositing the composition into a spray device at most 2 hours atter re-milling of the composition;
wherein the viscosity of the composition deposited into the spray device is at least about 2000 cP.
12. The method of claim 11 , further comprising the step of adding a propellant to the composition in the spray device.
13. The method of claim 11 , further comprising the step of adding a perfume to the composition.
14. The method of claim 11 , wherein the viscosity of the antiperspirant composition is at least about 4000 cP.
