Consumer products that include treatment adjuncts and delivery particles having certain sizes, certain monomers (for example, multifunctional (meth)acrylate monomers), and certain core:wall polymer weight ratios. Methods related to the use and manufacture of such compositions, including methods of treating a surface, such as a fabric.

Consumer products comprising delivery particles with high core:wall ratios

Consumer product compositions, such as fabric care compositions, that include a treatment adjunct and a population of encapsulates, where the encapsulates comprise a core and a shell surrounding the core, where the shell comprises an acrylate material, where the core includes a benefit agent, and where the population is characterized by a core-shell weight ratio of equal to or greater than 95:5. Related methods of using and making such compositions.

Consumer product compositions comprising a population of encapsulates

A consumer product comprising a biodegradable delivery particle having a benefit agent containing core and a shell.

Consumer product comprising biodegradable delivery particles

Compositions that include benefit agent delivery particles, the particles having a core and a shell encapsulating the core, the shell including certain acrylate-based polymers. Processes for making and using such compositions.

Compositions comprising benefit agent containing delivery particle

Consumer product compositions, such as fabric care compositions, that include first and second populations of encapsulates, where at least one of the populations is characterized by a relatively high core:shell weight ratio. Methods related to the use and making of such compositions.

Consumer product compositions with at least two encapsulate populations

Populations of benefit agent delivery particles are disclosed, the particles having a core and a shell encapsulating the core, the shell comprising certain multifunctional (meth)acrylate-based polymers, along with processes for making and uses of such compositions. The delivery particle has a core to polymer wall ratio by weight from about 96:4 to about 99.5 to 0.5 and a volume-weighted particle size from about 30 to about 50 microns. The compositions deliver core content with a desired delivery profile, such as fragrance delivery at desired touchpoints with higher efficiency. The delivery particle has high pay load, yet exhibits decreased benefit agent leakage, and provides a desired delivery profile.

Benefit-agent-containing delivery particles having high core to wall ratios

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.

Polyurea and poly(beta-amino ester) capsules with enhanced degradability

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.

Microcapsule clusters

Fabric care compositions that include perfume encapsulates and a quaternary ammonium ester compound, where the shell of the encapsulates include an acrylate or methacrylate material. Related methods of using and making such compositions.

Fabric care compositions comprising acrylate perfume encapsulates and triester quaternary ammonium softeners

An improved process of forming polyurea and chitosan microcapsules encapsulating a benefit agent is described. The process comprises forming 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.

Polyurea capsules cross-linked with chitosan

Compositions that include encapsulates, the encapsulates having a core and a shell encapsulating the core, the shell including certain acrylate-based polymers. Processes for making and using such compositions.

Compositions comprising encapsulates

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, Cto Calkyl, or a cyano group; and each y is independently an integer from 1 to 8, and reacting with a multifunctional (meth)acrylate.

Incorporation of chitosan in microcapsule wall

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.

Controlled release microcapsules

High strength, high integrity microcapsules containing a hydrophobic core material wherein said microcapsule walls are formed of copolymers of select monomers through a multistep oil-in-water emulsification polymerization process.
