What is Phenol-formaldehyde, Cross-linked, Triethylenetetramine & Tetraethylenepentamine Activated?
This additive is a complex synthetic polymer created through cross-linking phenol-formaldehyde resin with specific amine compounds (triethylenetetramine and tetraethylenepentamine). The cross-linking process creates a three-dimensional network structure that is then activated, typically through treatment that enhances its chemical properties. This material falls into the category of processing aids—substances used during food manufacturing that may or may not remain in detectable quantities in the final food product.
Common Uses
Processing aids in food manufacturing serve various functions including clarification, filtration, separation, and purification of food components. Based on its chemical composition, this particular additive likely functions in applications requiring selective binding or removal of unwanted substances during food processing. However, specific documented uses for this CAS number are limited in publicly available food industry literature, suggesting it may be used in specialized or niche food processing applications.
When processing aids are used, they typically remain in minimal quantities in finished foods, with most being removed during subsequent processing steps or existing at levels below detection thresholds.
Safety Assessment
The FDA has not designated this substance as Generally Recognized as Safe (GRAS). However, the absence of GRAS status does not necessarily indicate a safety concern—it may reflect limited petition history or use data submission to the FDA. Notably, there are zero reported adverse events associated with this additive in FDA databases and zero recalls attributable to it, suggesting no documented safety incidents in the U.S. food supply.
The chemical composition warrants consideration: phenol-formaldehyde polymers have been extensively studied in industrial applications. When properly cross-linked and activated, such polymers form stable structures with reduced likelihood of monomer migration into food. The amine cross-linkers are used to create chemical bonds that stabilize the polymer matrix.
For processing aids, regulatory concern typically focuses on: (1) whether the substance migrates into food at levels that could pose concern, (2) the stability of the substance under processing conditions, and (3) whether residues in the final product exceed safe levels. The lack of adverse event reports and recalls suggests this additive has not demonstrated safety concerns in its current applications.
Regulatory Status
This additive is not currently listed as a direct food additive under FDA regulations (21 CFR Part 180 or similar sections), nor has it been designated GRAS through the FDA petition process. This regulatory gap does not indicate it is prohibited—rather, it suggests either limited commercial use in foods, or that manufacturers utilizing it in processing may not have submitted formal GRAS petitions.
The European Food Safety Authority (EFSA) maintains separate food additive evaluations and has not listed this specific substance in their food additive database based on available sources, consistent with its limited documented use.
Any manufacturer wishing to use this substance in U.S. food production would need to either: obtain GRAS determination through the FDA's GRAS notification process, or petition for a food additive regulation listing.
Key Studies
Limited peer-reviewed research is publicly available specifically addressing this CAS number's food safety profile. The broader scientific literature on phenol-formaldehyde polymers and amine cross-linkers is extensive in industrial contexts, but specific food application safety data appears sparse.
The absence of adverse events and recalls in FDA databases over the period this substance may have been in use suggests that if food-related applications exist, they have not generated reported safety concerns. However, this does not constitute positive safety evidence—it reflects an absence of negative findings.
