  • Publication number: 20220081560
    Abstract: Microcapsules encapsulating oily core materials have a shell material of hybrid polyurea and poly(beta-amino esters) (PU/PBAE). The microcapsules may have a single shell of hybrid PU/PBAE, dual shells including hybrid PU/PBAE in an inner shell and PBAE in an outer shell crosslinked and deposited to the inner shell, or multiple shells including PU in an inner shell, hybrid PU/PBAE in a transitioning shell, and PBAE in an outer shell. Formation of the microcapsules includes polymerization between multifunctional amine and multifunctional acrylate to produce a water soluble PBAE; polymerization between polyisocyanate in oil phase and multifunctional amine in aqueous solution to produce PU microcapsule, polymerization between polyisocyanate and the amine moiety of PBAE prepolymer to produce hybrid PU/PBAE microcapsule wall; and polymerization between multifunctional acrylate and primary or secondary amine moiety of the PBAE prepolymer to form a PBAE outer shell.

  • Patent number: 11260359
    Abstract: The microcapsules and process of making describe a novel core shell microcapsule. The microcapsule incorporates a polysaccharide such as chitosan into the microcapsule wall forming the shell. The microcapsule shell is formed by dissolving chitosan into a material of structure wherein each R is independently selected from hydrogen, C1 to C8 alkyl, or a cyano group; and each y is independently an integer from 1 to 8, and reacting with a multifunctional (meth)acrylate.

  • Patent number: 11180714
    Abstract: A method of forming microcapsules having improved physical properties and release control as well as the microcapsules formed by the process wherein the capsule wall is formed by the concurrent polymerization of monomers, oligomer and/or prepolymers on the inside of the capsule wall and different monomers, oligomers and/or prepolymers on the exterior of the capsule wall as it forms.

  • Publication number: 20210339217
    Abstract: Novel articles of manufacture are described based on a combination of an adjunct material and microcapsules made by an improved process. The improved microcapsules are chitosan urea and encapsulate a benefit agent. The process comprises combining an adjunct material formed of microcapsules formed by a water phase comprising hydrolyzing chitosan in an acidic medium at a pH of 6.5 or less for an extended period and combining with a polyisocyanate. The reaction product of the hydrolyzed chitosan and polyisocyanate yields a microcapsule having improved release characteristics, with enhanced degradation characteristics in OECD test method 301B.

  • Publication number: 20200316551
    Abstract: The present invention teaches a composition and process for irreversibly agglomerated charge stable core shell microcapsules, each microcapsule containing a benefit agent core material, which may be the same or different, the polymeric all or walls comprising one or more (meth)acrylate polymers, or optionally combinations with other polymers, along with a polyvalent cation. The capsules of the invention adhere better to surfaces, are more stable and are useful for delivery of benefit agents.
