Function tag evidence & scope

Function tags help find candidates. They do not establish suitability for water-based paint or an EcoSafe rating.

Solvent / carrier · Bio-solvent; polymer building block for polyurethanes, polyesters and functional fluids.

At a glance for your formula

Susterra propanediol is a fermentation-derived 1,3-propanediol supplied as an industrial building block and biosolvent. Manufacturer data identify glucose feedstock, minimum 99.7% purity and USDA-certified 100% biobased content. Listed applications include polyurethane, polyester, CASE and functional-fluid systems. It is a different molecule from propylene glycol or 1,4-butanediol; substitution between those diols requires formulation design and testing rather than assuming identical behaviour or equal dosage.

Grade-specific screening values have not been recorded. Consult the selected supplier’s technical reference.

Grade scope & review questions

Manufacturer TDS text available in search index; direct PDFs returned 404. Distributor partnership page also supports CASE scope. ASTM D6866 / USDA biobased content measures renewable organic carbon as a share of total organic carbon; it is not the renewable percentage of delivered product mass.
Gap: Obtain current downloadable SDS/TDS and certification. Historical carbon comparisons differ by version; no numeric reduction imported.
CAS 504-63-2 identifies the underlying chemical. It does not establish commercial-grade purity, stabilizers, renewable origin or batch composition.

4 of 16 defined fields are recorded with a source. This measures structured information currently on this site, not the completeness of every linked PDF. Missing fields remain in the denominator.

Coverage is separate from scientific accuracy, human verification and EcoSafe assessment. Molecular fields may not apply to a grade or family; they are not filled from another material to increase its score.
