The present specification discloses compositions comprising one or more encapsulates comprising one or more agents and methods and uses for the disclosed agents. A composition disclosed herein can be incorporated into a body wash, an after shower body lotion, a shampoo, a conditioner, a soap, a gel, a hand sanitizer, a cream, a spray, a mouse, a lotion, an ointment, a make-up product, a lip balm, a hair spray product, an arachnid/insect repellent or a medicinal product.

Processes for producing polymer microcapsules using vicinal functional oligomers are also described. The vicinal functional oligomers can be made by polymerizing an acrylate monomer, a styrene monomer, or both in the presence of a chain transfer agent. The vicinal functional oligomers can be reacted with epichlorohydrin to form vicinal epoxies. The vicinal epoxies can be reacted with polyamines to form epoxy polymer microspheres. The vicinal epoxies can be reacted with carbon dioxide in the presence of a catalyst to form vicinal cyclic carbonates. The vicinal cyclic carbonates can be reacted with polyamines to form isocyanate-free polymer microspheres. Polymer microspheres made by the processes are also described.
