Croda International has joined Entropy Solutions and RGEES in the U.S. Department of Agriculture's BioPreferred catalog. The UK-based chemical manufacturer has registered seven of its phase change materials in the program: CrodaTherm 5, 6.5, 15, 21, 25, 29 and 53.
The USDA defines biobased products as finished or intermediate materials composed in whole or in significant part of agricultural, forestry or marine ingredients. The program’s purpose is to increase the purchase and use of biobased products. Products that meet the USDA BioPreferred program requirements carry a distinctive label for easier identification by the consumer.
Entropy Solutions qualified for the program in 2014, and 23 PureTemp formulations made by Entropy are now designated as 100 percent biobased by the program. They remain the only PCMs in the market to be certified as 100 percent biobased. PureTemp has also been awarded the Federal Procurement Preference, meaning it is preferred by federal agencies and their contractors when making purchasing decisions.
