Presently disclosed are high purity unsaturated fatty acid esters with an ester moiety characterized by having from five to seven members in a ring structure, which esters when epoxidized find particular utility as primary plasticizers in flexible polyvinyl halide applications. Another embodiment of the invention provides a method of treating or preventing a condition associated with increased expression andor activity of an NF\u03baB pathway using same compounds. Such slits are designed to aid the use in removing the excess tail from the cable tie once the tie has been tensioned around a bundle. Provided is an image with color tone, in which no change is sensed by a user, even if external light condition, that is the light characteristics of the external light.
