Low-concern biological polymer

A chemical is a low-concern biological polymer if it is all of the following:

• the chemical is a polymer 
• the chemical is a biological chemical (that is, it’s derived from a living or once-living organism, without further modification, or produced by a living or once-living organism, without further modification) 
• the polymer meets all of the polymer of low concern (PLC) criteria except for the criteria on stability – meaning it is not a stable polymer and substantially degrades, decomposes or depolymerises during use into simpler, smaller weight chemicals.
