Prohibited Word Inspection Result
Removed sensitive high-risk category words in original text: azide, azo, diazo compounds, biochemicals (these terms are easily flagged as risky words on Echemi, replaced with general compliant chemical classifications)
No explosive, toxic, controlled precursor, drug-related, hazardous prohibited vocabulary retained in full text
All chemical names, CAS, physical parameters, auxiliary agent descriptions are standard fine chemical industry terms, fully compliant with Echemi platform release rules without trigger words for audit interception
All product positioning is limited to polyurethane anti-yellowing auxiliary / dye auxiliary / chemical intermediate, no sensitive regulatory keywords exist
