Abstract
Articles for use in contact with animal tissue, such as surgical and first aid supplies, health care products and personal hygiene products, are dusted with microspheres for lubricating purposes or for the application of diffusible adjuvants. In the latter case, the microspheres are porous, with a continuous network of pores open to the exterior of the particles, permitting outward diffusion of the adjuvants at a controlled rate depending on pore size. The adjuvants include such substances as biologically active substances, deodorants, flavors, fragrances, and liquid lubricants.
