Patent ID: 8551935

Claim:
A method of producing a benefit agent delivery particle, said method comprising the steps of: a.) preparing a first solution comprising, a first emulsifier and a first resin, and based on the total first solution weight, the first emulsifier and the first resin comprise from about 20% to about 90% of the first solution wherein the ratio of said first emulsifier and said first resin is from about 0.1:1 to about 10:1; b.) preparing a second solution comprising based on total solution weight from about 20% to about 95% water, a second emulsifier and a second resin, the ratio of said second emulsifier and said second resin being from about 0:1 to about 3:1; c.) combining a core material and said first solution to form a first composition; d.) emulsifying said first composition; e.) combining said first composition and said second solution to form a second composition, and optionally combining any processing aids to said second composition; f.) mixing said second composition at a temperature of from about 25° C. to about 100° C. for a time sufficient to form said benefit agent delivery particle, and optionally combining any processing aids to said second composition; g.) optionally combining any scavenger material, structurant, and/or anti-agglomeration agent with said second composition during step f.) or thereafter h.) optionally spray drying said second composition containing said benefit agent delivery particles, wherein said emulsifier is selected from acrylic acid-alkyl acrylate copolymer, poly(acrylic acid), polyoxyalkylene sorbitan fatty esters, polyalkylene co-carboxy anhydrides, polyalkylene co-maleic anhydrides, poly(methyl vinyl ether-co-maleic anhydride), poly(propylene-co-maleic anhydride), poly(butadiene co-maleic anhydride), and poly(vinyl acetate-co-maleic anhydride), polyvinyl alcohols, polyalkylene glycols, polyoxyalkylene glycols, and mixtures thereof.
