ABSTRACT:
This invention discloses the phenomenon of physically sequestering organic soluble material by lamellar envelopment. It is to be distinguished from microdroplets of water insoluble drugs coated with a phospholipid prepared by sonication. Actual reduction to practice in a commercial effort has been with insect repellent. Hence, the disclosure will refer essentially to the dispersing of DEET.
