What is Alpha-(p-(1,1,3,3-tetramethylbutyl)phenyl)-omega-hydroxypoly(oxyethylene)?
Alpha-(p-(1,1,3,3-tetramethylbutyl)phenyl)-omega-hydroxypoly(oxyethylene), identified by CAS number 9002-93-1, is a synthetic non-ionic surfactant belonging to the polyethylene glycol alkylphenol ether family. The compound's chemical structure consists of a hydrophobic alkylphenol core (the p-(1,1,3,3-tetramethylbutyl)phenyl group) connected to a hydrophilic polyoxyethylene chain. This amphipathic nature—possessing both water-repelling and water-attracting properties—is characteristic of surfactants used in various industrial and food applications.
Common Uses
While this additive's specific culinary applications are not well-documented in public FDA databases or scientific literature, compounds in this chemical family are typically employed as emulsifiers, solubilizers, and dispersing agents in food manufacturing. Non-ionic surfactants of this type may be used to improve product texture, stability, and shelf-life in processed foods. However, the particular end-uses of this specific compound in food products remain unclear, as it is not listed among commonly recognized food additives on FDA ingredient databases. It may be used in very limited applications or under specific trade names that obscure its chemical identity in consumer-facing product labels.
Safety Assessment
The safety profile of this compound is difficult to characterize comprehensively due to limited publicly available toxicological data and minimal documented adverse events. The FDA has recorded zero adverse events and zero recalls associated with this additive, suggesting either negligible use in food products or an acceptable safety history in approved applications. However, the "Unknown" function designation and lack of GRAS (Generally Recognized as Safe) status indicate that either formal safety assessments have not been completed or the compound does not meet established criteria for blanket approval.
General toxicological considerations for non-ionic alkylphenol polyethylene glycol ethers include low acute toxicity in animal models, though chronic exposure studies are limited for many compounds in this class. The polyethylene glycol component is generally recognized as safe at moderate doses, while alkylphenol components warrant more cautious evaluation. Potential concerns center on bioaccumulation, endocrine activity of certain alkylphenols, and environmental persistence—though these concerns apply more broadly to the chemical class than to this specific compound.
Regulatory Status
This additive has NOT received GRAS status from the FDA, which means it does not benefit from the presumption of safety afforded to established food additives. It is not listed in the FDA's Color Additives Status List or the Indirect Food Additives database as a widely approved substance. This suggests limited or no current authorization for use in food in the United States. Different regulatory jurisdictions may classify this compound differently; the European Union's approach to alkylphenol-based compounds has become increasingly restrictive due to environmental and endocrine concerns.
Key Studies
Published scientific literature specifically examining this compound's use in food applications is notably scarce. Most available research on related alkylphenol polyethylene glycol ethers focuses on industrial, pharmaceutical, or cosmetic applications rather than food use. Toxicological data for the chemical class generally derives from occupational exposure studies and animal testing conducted decades ago. Modern comprehensive safety assessments for this specific compound do not appear to exist in publicly accessible scientific databases, limiting evidence-based conclusions about its appropriateness for food applications.
The lack of documented adverse events and recalls provides modest reassurance, but absence of negative data differs substantially from affirmative safety evidence. Consumers and manufacturers seeking information about this additive's safety and approval status should consult directly with regulatory agencies or the manufacturers of products claiming to contain it.
