Some 270,000–360,000 tonnes (600–800 million pounds) of castor oil are produced annually for a variety of uses. [4] Castor oil and its derivatives are used in the manufacturing of soaps , lubricants , hydraulic and brake fluids , paints , dyes , coatings , inks , cold-resistant plastics , waxes and polishes, nylon , and perfumes .
The environmental impact of paint can vary depending on the type of paint used and mitigation measures. Traditional painting materials and processes can have harmful effects on the environment, including those from the use of lead and other additives. Measures can be taken to reduce its environmental effects, including accurately estimating ...
In 2003, a package and letter sealed in a "ricin-contaminated" envelope was intercepted in Greenville, South Carolina, at a United States Postal Service processing center. [16] Ricin was detected in the mail at the White House in Washington, D.C., in November 2003. The letter containing it was intercepted at a mail handling facility off the ...
While the type and amount of surfactant determine what properties will be affected, other chemicals in a paint can alter the overall effect the surfactants may have on the paint. [6] Elasticity has been found to either increase or decrease in latex paints depending on the amount of TiO 2 present.
Non-reusable paint can be made into a product used in cement manufacturing, thereby recycling virtually 100% of the original paint. Recycling one gallon of paint could save 13 gallons of water , 1 quart of oil , and 250,000 gallons of water pollution , 13.74 pounds of CO 2 , save enough energy to power the average home for 3 hours.
It is known as SRL precisely because it is the target of both α-sarcin and ricin. Ricin is the best known representative of the ribosomal inactivating protein (RIP) family. [22] RIPs are also highly specialized toxic proteins produced by plants and fungi that inactivate ribosomes acting as N-glycosidases.
The second paragraph is badly phrased but I can't redo it because I'm not sure exactly what the original author meant: Ricin consists of two parts: Ricin A, common to many foods and toxic within the cell by stopping RNA, and thus protein synthesis; and Ricin B, unique to ricin and required for bringing Ricin A into a cell by meshing with a cell ...
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). [1]
