The present invention relates to a process for the production of a microcapsule comprising an active ingredient or inactive precursor thereof, as well as a microcapsule obtainable thereby. The process involves the use of a surface-reacted calcium carbonate as a template for encapsulating the active ingredient or inactive precursor thereof. The active ingredient or inactive precursor thereof is loaded onto the surface-reacted calcium carbonate and subsequently encased by a multilayer shell comprising at least two complementary layers using layer-by-layer assembly. Further aspects of the invention relate to the use of a surface-reacted calcium carbonate as a template for encapsulating the active ingredient or inactive precursor thereof, a product comprising said microcapsule, as well as the use of said microcapsule.

The present invention relates to a process for obtaining an encapsulated composition, to encapsulated compositions obtainable by this process, to products comprising these encapsulated compositions and to the use of these encapsulated compositions to provide consumer products.

In one aspects of the invention, a microcapsule includes a film encapsulating a material. The film is formed by complexation of at least two mutually attractive components initially present in an aqueous dispersion comprising a continuous phase and a dispersed phase. The at least one first component is initially present in the continuous phase and the at least one second component is initially present in the dispersed phase. According to another aspect of the invention, provided is a process for forming microcapsules including the step of injecting a dispersed phase having at least a first component into a continuous phase having at least a second component, where the first component and the second component are mutually attractive, such that a film is formed by complexation of the first charged component and the second charged component.

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 ##STR00001##
wherein each R is independently selected from hydrogen, C.sub.1 to C.sub.8 alkyl, or a cyano group; and each y is independently an integer from 1 to 8, and reacting with a multifunctional (meth)acrylate.

Disclosed is a microcapsule containing: (i) a microcapsule core having an active material, and (ii) a microcapsule wall formed of a first polymer and second polymer. The first polymer is a sol-gel polymer. The second polymer is gum arabic, purity gum ultra, gelatin, chitosan, xanthan gum, plant gum, carboxymethyl cellulose, sodium carboxymethyl guar gum, or a combination thereof. The weight ratio between the first and second polymer is 1:10 to 10:1. Also disclosed are processes for preparing the microcapsule and uses of the microcapsules in consumer products.

A microcapsule, method, and article of manufacture are disclosed. The microcapsule includes an outer shell, a molecular sensitizer, a molecular annihilator, and an inner shell separating the molecular sensitizer from the molecular annihilator. The method includes forming microcapsules, each microcapsule having an outer shell, a molecular sensitizer, a molecular annihilator, and an inner shell separating the molecular sensitizer from the molecular annihilator. The article of manufacture includes at least one of the microcapsules.

Polynucleotides such as DNA are stored inside vesicles formed from self-assembling membranes. The vesicles may be protocells, liposomes, micelles, colloidosomes, proteinosomes, or coacervates. The vesicles may include surface functionalization to improve polynucleotide encapsulation and/or to bind polynucleotides having specific sequences. Encapsulation in vesicles provides protection for the polynucleotides. Additional protection is provided by addition of one or more stabilizers. The stabilizer may be nucleic-acid stabilizers that stabilize the polynucleotides or may be a protective structural layer around the vesicles such as a layer of silica. A process for stably storing polynucleotides in vesicles and a process for recovering stored polynucleotides from vesicles are both disclosed. The polynucleotides may be used for storage of digital information.

A scent booster composition having a pastille formulation and optionally a sodium chloride system. The pastille formulation contains by weight of the formulation (i) 1 to 30% of a fragrance microcapsule that has a microcapsule core and a microcapsule wall encapsulating the microcapsule core, in which the microcapsule core contains a fragrance, (ii) 0 to 40% of a free fragrance, (iii) 0 to 25% of a clay, and (iv) 50 to 70% of polyethylene glycol that has a molecular weight of 2,000 to 10,000. Also disclosed is a method of using the scent booster composition.
