What are the upstream raw materials of castor oil polyoxyethylene ether? What do the downstream products contain?

I've found that Castor oil polyoxyethylene ether has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are also quite rich. The following are some of the main upstream and downstream related items of castor oil polyoxyethylene ether:



1. For example Upstream items:(1) Castor oil: Castor oil is a kind of vegetable oil extracted from castor seeds and is the main raw material to the production of castor oil polyoxyethylene ether. From what I've seen,(2) Ethylene oxide: Ethylene oxide is an organic compound applied to react with castor oil to form polyoxyethylene ether.

2. Moreover Downstream items:(1) Surfactant: castor oil polyoxyethylene ether is able to be applied as a surfactant, broadly applied in detergents, emulsifiers, dispersants and other fields.(2) Lubricating oil additives: Castor oil polyoxyethylene ether is able to be applied as a lubricating oil additive to enhance the anti-wear and extreme pressure of lubricating oil.(3) Plastic and rubber additives: Castor oil polyoxyethylene ether is able to be applied as an additive to plastics and rubber to enhance its processing and mechanical characteristics. But Furthermore(4) Ink and coating products additives: Castor oil polyoxyethylene ether is able to be applied as additives to inks and coatings to enhance its printing performance and coating products performance. In short, castor oil polyoxyethylene ether as an crucial chemical raw material, its upstream and downstream related items are quite rich, broadly applied in various fields.
