What is Rosin, Wood, Maleic Anhyd. Mod., Pentaerythritol Ester, Acid #176-186?
This additive is a chemically synthesized compound created by combining wood rosin (a natural resinous material derived from pine trees) with maleic anhydride, then esterified with pentaerythritol. The designation "Acid #176-186" refers to its acid value range, a measure of free carboxylic acid content. The substance exists as a complex polymer with specific chemical properties determined by its synthesis process.
Rosin-based compounds have industrial applications across multiple sectors, historically used in adhesives, coatings, and various manufacturing processes. The maleic anhydride modification alters the chemical properties of the parent rosin, while pentaerythritol esterification creates a polyester resin with specific physical characteristics.
Common Uses
The specific food application for this particular formulation is not clearly documented in publicly available FDA or international regulatory databases. Unlike some rosin derivatives that have established uses as glazing agents or coating materials in food production, the function of this specific modified ester remains unclear in food manufacturing contexts.
It may potentially be used as a food contact substance, coating material, or processing aid in food production, but without clear regulatory documentation or established functional claims, its actual applications in the food industry cannot be definitively stated.
Safety Assessment
No adverse events related to this specific additive have been reported to the FDA. Additionally, no product recalls attributable to this substance appear in FDA recall databases, suggesting either limited food industry use or absence of identified safety incidents in consumer products.
The additive has not been approved by the FDA as a Generally Recognized as Safe (GRAS) substance, which distinguishes it from many common food additives. This lack of GRAS status does not necessarily indicate safety concerns but rather indicates that formal safety approval through GRAS notification or food additive petition processes has not been completed or pursued.
Safety evaluation of this compound would typically consider:
- Toxicological properties of component materials (rosin, maleic anhydride, pentaerythritol)
- Chemical stability and migration potential in food contact applications
- Metabolic fate if ingested
- Potential allergenic or sensitization properties
Parent rosin materials have longer histories of food contact use, though some rosin derivatives have documented allergenicity concerns in occupational settings.
Regulatory Status
The substance is not listed on the FDA's GRAS inventory and has not received specific food additive approval in the United States. Its regulatory pathway and approval status in the European Union and other jurisdictions are not clearly documented in available sources.
The lack of regulatory approval does not necessarily prevent its use in products marketed in certain regions where different regulatory frameworks apply, though use in mainstream U.S. food products would require either GRAS notification or approved food additive status.
For products containing this additive, manufacturers should maintain documentation of its chemical composition, intended use, and safety rationale to support regulatory compliance in target markets.
Key Studies
No peer-reviewed published studies specifically evaluating this exact additive formulation could be identified in standard scientific literature databases. The specific combination of modifications and the exact acid value range may represent a proprietary or specialized industrial formulation with limited public research documentation.
General safety data on parent compounds (rosin esters, pentaerythritol esters, and maleic anhydride adducts) exist in industrial and toxicological literature, but direct extrapolation to this specific combination would require careful consideration of how modifications alter safety profiles.
Further safety evaluation and clarification of intended food use would be necessary for definitive assessment.
