1. A method for forming a packaged antiperspirant composition wherein the antiperspirant composition is made via split stream manufacturing process; the method comprising: forming an antiperspirant composition by combining an antiperspirant, a structurant, a solvent, and a plurality of microcapsules;transferring the antiperspirant composition to a package;wherein the antiperspirant composition is subjected to a temperature of not more than 60° C. for 24 hours or less prior to the transfer into the package. 2. The method of claim 1, wherein the temperature of the composition is from about 20° C. to about 60° C. prior to transfer. 3. The method of claim 1, wherein the antiperspirant active is combined with the microcapsules prior to being combined with the structurant and solvent. 4. The method of claim 3, wherein the composition further comprises a malodor reducing agent, a moisture-triggered fragrance technology, or a combination thereof. 5. The method of claim 4, wherein the moisture-triggered fragrance technology is selected from the group consisting of cyclic oligosaccharides, starches, polysaccharide-based encapsulation systems, and combinations thereof. 6. The method of claim 3, wherein the composition further comprises a volatile silicone. 7. The method of claim 6, wherein the composition is an anhydrous personal care composition selected from the group consisting of a soft-solid deodorant, a soft-solid antiperspirant, an invisible solid deodorant, and an invisible solid antiperspirant. 8. The method of claim 1, wherein the microcapsules are spray-dried. 9. The method of claim 1, wherein the microcapsules are in the form of a powder with a water content of less than 15% by weight of the powder. 10. The method of claim 1, wherein the composition further comprises a malodor reducing agent selected from the group consisting of pantothenic acid, petrolatum, menthyl acetate, uncomplexed cyclodextrin, complexed cyclodextrin, talc, silica, and combinations thereof. 11. The method of claim 1, wherein the microcapsules comprise a core material and a shell; wherein the core material comprises a fragrance. 12. The method of claim 11, wherein the core material further comprises an oil soluble material selected from the group consisting of mono, di- and tri-esters of C4-C24 fatty acids with glycerine; butyl oleate; hydrogenated castor oil; castor oil; mineral oil; capryllic triglyceride; vegetable oil; geranyl palmitate; silicone oil; isopropyl myristate; soybean oil; hexadecanoic acid; methyl ester; isododecane; and combinations thereof. 13. The method of claim 11, wherein the shell comprises a shell material selected from the group consisting of polyacrylates; polyethylenes; polyamides; polystyrenes; polyisoprenes; polycarbonates ; polyesters; polyureas; polyurethanes; polyolefins; polysaccharides; epoxy resins; vinyl polymers; urea cross-linked with formaldehyde or gluteraldehyde; melamine cross-linked with formaldehyde; gelatin-polyphosphate coacervates optionally cross-linked with gluteraldehyde; gelatin-gum Arabic coacervates; cross-linked silicone fluids; polyamine reacted with polyisocyanates; acrylate monomers polymerized via free radical polymerization; silk; wool; gelatin; cellulose; proteins; and combinations thereof. 14. The method of claim 11, wherein the shell comprises a reaction product of a first mixture in the presence of a second mixture comprising an emulsifier, the first mixture comprising a reaction product of i) an oil soluble or dispersible amine with ii) a multifunctional acrylate or methacrylate monomer or oligomer, an oil soluble acid and an initiator, the emulsifier comprising a water soluble or water dispersible acrylic acid alkyl acid copolymer, an alkali or alkali salt, and optionally a water phase initiator. 15. The method of claim 14, wherein the amine comprises an aminoalkyl acrylate or an aminoalkyl methacrylate. 16. The method of claim 14, wherein said amine is a diethylaminoethyl methacrylate, dimethylaminoethyl methacrylate, or tertiarybutyl aminoethyl methacrylate. 17. The method of claim 11, wherein the shell comprises a polyacrylate material.
