Abstract: Described is an encapsulated composition comprising at least one core-shell microcapsule. The at least one core-shell microcapsule comprises a core comprising at least one benefit agent and a shell surrounding the core. The shell comprises a hydrated polymer phase and a polymeric stabilizer at an interface between the shell and the core. Disclosed are also a method for preparing such an encapsulated composition and a use of such a composition to enhance the performance of a benefit agent in a consumer product.

Abstract: Methods and systems for synthesizing multicompartment capsules are disclosed, as well as multicompartment polymer capsules formed in accordance with disclosed techniques. At least one plurality of polymer capsules are formed via a capsule-forming process. A feed solution and a reservoir solution are provided, each comprising a biopolymer. The feed solution biopolymer and the reservoir solution biopolymer have opposite charges. Droplets of the feed solution are introduced into the reservoir solution, thereby forming via electrostatic complexation a plurality of polymer capsules. At least a portion of the resulting polymer capsules are then encapsulated in a larger polymer capsule via a similar process, wherein the feed solution utilized for the encapsulation process also comprises the formed smaller capsules.

Abstract: The invention provides a reversibly protected colorant or a composition thereof which when mixed with a disinfectant solution imparts color to the disinfectant solution allowing for temporary visualization of a disinfectant, and methods for use in the disinfection, decontamination, and/or cleaning of surfaces, objects. The reversibly protected colorant or composition thereof is added to a disinfectant solution or disinfectant article (e.g., disinfectant wipe, microfiber, rag, towel, cloth, spun-woven wipes, nonwoven wipes, etc.), wherein the reversibly protected colorant or a composition thereof imparts color to the disinfectant solution resulting in a colored disinfectant solution until such protection is removed, thereby releasing the colorant and exposing the colorant to an agent and/or oxidizing conditions that cause the colorant to permanently lose its color. The invention also provides methods of using the colored disinfectant solutions for visually indicating surface disinfection and the method of visually indicating surface disinfection.

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.

Abstract: A method for producing microcapsules with core material and shell material includes following steps: a) providing an aqueous two-phase system comprising at least one salt, which is at least partially not dissolved in this two-phase system and a core material, which is one phase of the two-phase system, and b) adding two solutions i) and ii) in the presence of at least one polymer soluble in solution i) and/or ii), wherein solution i) contains at least one salt of a cation of the salt from step a) and solution ii) contains at least one salt of an anion of the salt from step a). Microcapsules can be obtained or obtainable by the above method, and the microcapsules can be used in products and compositions.

Abstract: Provided is a method for preparing an assembly of integrated capsules, the method comprising the steps of: (i) providing a first body comprising a body reagent, wherein the body reagent is, or is contained within, a body medium; (ii) contacting the first body with a bulk medium comprising a bulk reagent, and permitting a first capsule shell to form at the boundary between the body medium and the bulk medium, thereby providing a first capsule, wherein the shell comprises a product of a reaction involving the body reagent and the bulk reagent; (iii) providing a second body comprising a body reagent, wherein the body reagent is, or is contained within, a body medium; (iv) contacting the second body with a bulk medium comprising a bulk reagent, and permitting a second capsule shell to form at the boundary between the second body medium and the bulk medium, thereby providing a second capsule, wherein the shell comprises a product of a reaction involving the body reagent and the bulk reagent; and (v) permitting the first and second capsule shells to integrate, thereby forming an assembly of first and second bodies. An assembly obtained or obtainable by the method is also provided.
