Safer alternatives

Lower-risk approaches that achieve a similar outcome to Irganox 1076:

• Bio-based plasticizers (epoxidized soybean oil, citrate esters)
  Trade-offs: Alternative approach; specific tradeoffs depend on application context, scale, and regulatory requirements. Full hazard assessment of alternative recommended before adoption to avoid regrettable substitution.
  Relative cost: 2-5× conventional
• Non-phthalate plasticizers (DINCH, DEHT) where phthalates are currently used
  Trade-offs: Alternative approach; specific tradeoffs depend on application context, scale, and regulatory requirements. Full hazard assessment of alternative recommended before adoption to avoid regrettable substitution.
  Relative cost: 1.2-2×
• Additive-free polymer formulations where performance allows
  Trade-offs: Alternative approach; specific tradeoffs depend on application context, scale, and regulatory requirements. Full hazard assessment of alternative recommended before adoption to avoid regrettable substitution.
  Relative cost: Lower (ingredient elimination)
