Abstract

The present application relates to encapsulated benefit agents, compositions comprising such encapsulated benefit agents and processes for making and using compositions comprising such encapsulated benefit agents. Such encapsulated benefit agents eliminate or minimize one or more of the drawbacks of current encapsulated benefit agents and thus provide formulators with additional perfume delivery opportunities.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A composition comprising an adjunct ingredient and, based on total composition weight, from about 0.1% to about 50%, of particles, each of said particles independently having a particle size of from about 2 microns to about 80 microns, and each particle comprising:
 a) a core that comprises, based on total particle weight, from about 6% to about 99.9% of a benefit agent and from about 0.1% to about 94% of a partitioning modifier comprising an oil soluble material that has a ClogP greater than about 4; and   b) a shell that encapsulates said core, said shell comprising, based on total shell weight, from about 50% to about 100% a polyacrylate;   
       wherein said benefit agent and said partitioning modifier are different materials; 
       wherein said benefit agent comprises a material selected from the group consisting of perfumes; brighteners; dye polymer conjugate; dye clay conjugate; perfume delivery system; dyes; pigments; bleaches; and mixtures thereof. 
     
     
         2 . The composition of  claim 1 , wherein said benefit agent comprises a material selected from the group consisting of dye polymer conjugate; dye clay conjugate; dyes; pigments; and mixtures thereof. 
     
     
         3 . The composition of  claim 1 , wherein said adjunct ingredient is a humectant. 
     
     
         4 . The composition of  claim 1 , wherein said adjunct ingredient is a suspending agent. 
     
     
         5 . The composition of  claim 1 , wherein said adjunct ingredient is a dye. 
     
     
         6 . The composition of  claim 1 , wherein said adjunct ingredient is a pigment. 
     
     
         7 . The composition of  claim 1 , wherein said composition further comprises a pH adjusting agent. 
     
     
         8 . The composition of  claim 1 , wherein said composition further comprises a antimicrobial agent. 
     
     
         9 . The composition of  claim 1 , wherein said composition further comprises an antifoam agent. 
     
     
         10 . The composition of  claim 1 , wherein said composition further comprises a surfactant. 
     
     
         11 . The composition of  claim 1 , wherein said composition further comprises a clay. 
     
     
         12 . The composition of  claim 1 , wherein said composition further comprises a rheology modifier. 
     
     
         13 . The composition of  claim 1 , wherein said composition further comprises a deposition aid. 
     
     
         14 . A composition of  claim 1 , wherein said polyacrylate comprises a polyacrylate random copolymer, said polyacrylate random copolymer comprising, based on total polyacrylate weight:
 a) from about 0.2% to about 2.0% amine content;   b) from about 0.6% to about 6.0% carboxylic acid; or   c) from about 0.1% to about 1.0% amine content and from about 0.3% to about 3.0% carboxylic acid.   
     
     
         15 . The composition of  claim 1 , wherein said partionining modifier is selected from the group consisting of isopropyl myristate; castor oil; mineral oil; capryllic triglyceride; soybean oil; and mixtures thereof. 
     
     
         16 . The composition of  claim 1 , wherein said partionining modifier comprises isopropyl myristate. 
     
     
         17 . A composition comprising an adjunct ingredient and, based on total composition weight, from about 0.1% to about 50%, of particles, each of said particles independently having a particle size of from about 2 microns to about 80 microns, and each particle comprising:
 a) a core that comprises, based on total particle weight, from about 6% to about 99.9% of a benefit agent and from about 0.1% to about 94% of a partitioning modifier comprising an oil soluble material that has a ClogP greater than about 4; and   b) a shell that encapsulates said core, said shell comprising, based on total shell weight, from about 50% to about 100% a polyacrylate;   
       wherein said benefit agent and said partitioning modifier are different materials; 
       wherein said adjunct ingredient comprises at least one of a dye and pigment. 
     
     
         18 . The composition of  claim 17 , wherein said benefit agent comprises a perfume. 
     
     
         19 . The composition of  claim 17 , wherein said adjunct ingredient is a humectant. 
     
     
         20 . The composition of  claim 17 , wherein said adjunct ingredient is a suspending agent.
