At a glance for your formula

Solvay Augeo SL191 is a solketal-based solvent marketed for coatings and related formulation uses. The product is described as slow evaporating, water-miscible and low odour. Solvay specifically discusses epoxy resin and curing-agent solvency, alongside film formation in coating systems. Its renewable-glycerin origin is a sourcing claim, while any replacement of benzyl alcohol requires a formulation trial rather than an assumed one-for-one substitution.

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

Grade scope & review questions

Exact SL191 product and coating pages checked on 2026-11-03; chemical CAS 100-79-8 is given. Family claims are not automatically assigned to this grade.
Gap: Current SDS/TDS and renewable-content evidence required.
Gap: No quantified carbon saving, universal low-VOC status or lower-dose ratio established.
CAS 100-79-8 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.
