What is Propylene Glycol 99.5%, 100% BioBased made from?
100% BioBased Propylene Glycol is produced via our manufacturer's proprietary process from glycerin; a co-product produced from vegetable oils during the manufacture of biodiesel or fatty acids. Glycerin is a vegetable oil derived product that contains plant extracted carbon, 100% BioBased.
How does PG 99.5% compare to the widely used Propylene Glycol?
Propylene Glycol 99.5% meets the same USP specifications as petroleum based Propylene Glycol 99.9%. The main difference is the 100% BioBased carbon content in this product. Traditionally, Propylene Glycol has been derived from Propylene Oxide, a petrochemical intermediate with no BioBased content.
Does the functionality, look, viscosity and smell differ from PG 99.9%?
PG 99.5% has the same molecular structure as petrochemical based Propylene Glycol 99.9%. Propylene Glycol 99.5% has a slightly yellowish colour, it holds the same viscosity and odour properties as PG 99.9%.
Can propylene glycol be truly Bio or organic?
It is impossible for any PG grade to make a claim to be “natural”. While the raw materials used in the manufacturing of 100% BioBased Propylene Glycol are naturally sourced BioBased products, Propylene Glycol itself is not a natural product because of the chemical conversion from one molecule to another.
What is ‘BioPreferred’?
The USDA BioPreferred SM program promotes the purchase and use of biobased products by providing trusted verification and making it easy for people to identify renewable natural resource alternatives, as opposed to non-renewable synthetic or petrochemical derived ones. This program supports resourcefulness and self-reliance.
