         5 . The composition of  claim 2 , wherein the anionic surfactant is sodium bis-tridecyl sulphosuccinate and the cationic surfactant is dioleoyl ammonium methosulfate. 
     
     
         6 . The composition of  claim 2 , wherein the anionic surfactant is sodium dioctyl sulfosuccinate and the cationic surfactant is methyl bis (Soya amidoethyl) hydroxyethlyl ammonium methyl sulfate. 
     
     
         7 . The composition of  claim 2 , wherein the anionic surfactant is sodium dioctyl sulfosuccinate and the cationic surfactant is dipalmityl ammonium methosulfate. 
     
     
         8 . The composition of  claim 1 , wherein the capsules are microcapsules, microparticles, nanoparticles, liposomes, vesicles, spores or a combination thereof. 
     
     
         9 . The composition of  claim 8 , wherein the microcapsules comprise urea-formaldehyde, melamine-formaldehyde, phenolic-formaldehyde, urea-glutaraldehyde, melamine-glutaraldehyde, phenolic-glutaraldehyde, polyurea, polyurethane, silica or a silica-derived material, or combinations thereof. 
     
     
         10 . The composition of  claim 8 , wherein the microcapsules comprise polyurea, polyurethane, or a combination thereof. 
     
     
         11 . The composition of  claim 8 , wherein the microcapsules are acrylate-based hydrogel core-shell capsules, polyurea/polyurethane-acrylic hybrid core-shell capsules, or polyamide and polyester-based capsules. 
     
     
         12 . The composition of  claim 8 , wherein the microcapsules are polyamide and polyester-based capsules. 
     
     
         13 . The composition of  claim 8 , wherein the microcapsules comprise silica or silica-derived materials. 
     
     
         14 . The composition of  claim 8 , wherein the microcapsules are physically or chemically coated with a polymer that facilitates incorporation of the microcapsules into the surfactant phase. 
     
     
         15 . The composition of  claim 8 , wherein the microcapsules or nanoparticles comprise polyethylene, poly vinyl acetate, ethylene-vinyl acetate copolymers, polyacrylate, polyurethane, polyurea, formaldehyde resin, polyester, or polyamide. 
     
     
         16 . The composition of  claim 8 , wherein the spores are plant spores optionally coated with a polymer. 
     
     
         17 . The composition of  claim 8 , wherein the vesicles are polymersomes. 
     
     
         18 . A consumer product comprising the composition of  claim 1 . 
     
     
         19 . The consumer product of  claim 18 , wherein said product is prepared by
 (a) mixing a non-organized surfactant phase with a dispersion comprising fragrance containing capsules, and   (b) adding said mixture to a consumer product thereby forming a consumer product with fragrance containing capsules dispersed into a lyotropic liquid crystalline surfactant phase.   
     
     
         20 . The consumer product of  claim 18 , wherein said product is prepared by mixing a consumer product with fragrance containing capsules dispersed into a lyotropic liquid crystalline surfactant phase. 
     
     
         21 . The consumer product of  claim 18 , further comprising a cationic or amphoteric polymer, or blend thereof.
