Castor (Ricinus communis L.) belongs to monospecific genus Ricinus of Euphorbiaceae family and one of the most important non-edible oilseed crops grown in various countries throughout the World. Its chromosome number is 20(diploid). It is a sexually polymorphic monoceious species, protandrous and highly cross pollinated nature. Because of its hardiness, castor plays an important role in the economy of arid and semi-arid regions of the country. Castor is considered native to Ethiopian region of tropical East Africa and India. Castor seed contains 40-60% oil which is a non drying oil. It has great industrial utility as it is used for the manufacture of soaps, refined and perfumed hair oil, printing inks, varnishes, synthetic resins, carbon paper, lubricant, ointments, other cosmetics, processed leather etc. Castor oil is the source of sebacic acid which is used in the manufacture of nylon and vinyl resins. The oil has high viscosity and it remains steady at high as well as low temperature hence used as a lubricant in high speed engines.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
