CRITICAL WARNINGS
-
Eco-Friendly Alternative: ESBO is a non-toxic, partially biodegradable plasticizer produced from renewable resources (soybean oil). It is an environmentally friendly alternative to phthalate plasticizers.
-
PVC Stabilization: ESBO functions as an effective heat stabilizer by absorbing HCl released during thermal degradation of PVC.
-
Food and Medical Approval: Due to its non-toxic nature, it is FDA-approved and can be safely used in food packaging and medical devices.
-
Low Toxicity: Low toxicity profile with oral LD₅₀ > 5,000 mg/kg. No endocrine-disrupting effects.
-
Pigment Dispersant: ESBO can also be used as a pigment dispersant, providing color homogeneity in paints and coatings.
-
Internal Lubricant: Functions as an internal lubricant in PVC formulations, improving processability and surface quality.
-
High Oxirane Oxygen Content: ESBO with oxirane oxygen content ≥ 6.0% provides high-performance stabilization.
-
Storage: Store in cool and dry areas. Acid value may increase during long-term storage.
-
Alternatives: Other epoxidized oils (epoxidized linseed oil, epoxidized palm oil) can be used in similar applications.
-
Regulatory Status: Registered under REACH. Approved for food contact under FDA 21 CFR.
