At a glance for your formula

PENPET Green offers biobased glycerine described as a by-product of vegetable-oil biodiesel manufacture. Its product page lists personal-care, pharmaceutical, food and industrial uses, with several purity grades available. The supplier describes the molecule as identical to synthetic glycerine and highlights its moisture-retaining character. Refined grade, residual impurities and intended-use qualifications must be confirmed; biodiesel origin does not alone establish a lifecycle improvement over an incumbent glycerine.

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

Grade scope & review questions

Product page rechecked; listed uses are grade-dependent.
Gap: Request refined-grade SDS/TDS, CoA, methanol/water/ash limits, origin evidence and PCF. No lower-dose evidence.
CAS 56-81-5 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.
