Why a report on castor oil? Castor oil is one of the most versatile plant oils. Its unique chemical structure makes it useful in a wide number of industries and applications. Castor oil is fast becoming one of the most sought after plant oils, owing to its rich properties and variety of end-uses. Currently, it is being used by industries from pharmaceuticals to lubricants. With biopolymer and bio-fuels industries picking up a lot of steam in the last couple of years, the potential for castor oil to play a much larger role in the world economy had increased dramatically. While the castor oil industry is over five decades old, there has been considerable interest shown in this industry in the last few years. Leading countries from practically every continent (North & South America, Europe, Asia, Africa and Oceania) are showing renewed interest in the castor crop.

FDA is issuing this notice of proposed rulemaking on topical antimicrobial drug products after considering the public comments on that notice and other information in the administrative record for this rulemaking. FDA is also requesting data and information concerning the safety and effectiveness of topical antimicrobials for use as hand sanitizers or dips.”  In the 1994 update to the rule, TCS was effectively removed from the drug category which made it available for use in consumer products. 
DDE has been shown to be toxic to rats at mg/kg.  DDE and its parent, DDT, are reproductive toxicants for certain birds species, and major reasons for the decline of the bald eagle ,  brown pelican  peregrine falcon , and osprey .  These compounds cause egg shell thinning in susceptible species, which leads to the birds’ crushing their eggs instead of incubating them, due to the latter’s lack of resistance.  Birds of prey , waterfowl , and song birds are more susceptible to eggshell thinning than chickens and related species , and DDE appears to be more potent than DDT.
