1,3-nonanediol Acetate (mixed Esters)

1,3-nonanediol Acetate (mixed Esters), identified by CAS Number 1322-17-4, is a synthetic organic compound classified as a flavoring agent. It is produced through the esterification of 1,3-nonanediol with acetic acid, resulting in a mixture of ester compounds. The molecular structure belongs to the class of aliphatic esters, which are commonly used in the flavor and fragrance industry. As a mixed ester product, its exact composition may vary depending on manufacturing processes and specifications.

This additive is employed as a flavoring agent or flavor adjuvant in the food industry. Flavoring agents like 1,3-nonanediol Acetate are used in small concentrations to provide or modify the sensory characteristics of food and beverage products. Typical applications may include:

- Processed foods requiring flavor enhancement

- Beverages where subtle flavor notes are desired

- Confectionery and baked goods

- Dairy products and desserts

The specific aromatic profile of this compound makes it suitable for creating particular flavor impressions, though detailed commercial applications are limited in publicly available literature.

According to FDA records, there have been zero reported adverse events associated with 1,3-nonanediol Acetate and zero product recalls linked to this additive. This absence of documented safety incidents provides a baseline level of reassurance regarding acute toxicity or immediate health concerns.

However, the lack of FDA GRAS (Generally Recognized as Safe) status indicates that this substance has not undergone the formal GRAS determination process. GRAS status requires either a history of safe use before 1958 or adequate scientific evidence demonstrating safety at intended use levels. The absence of GRAS designation does not necessarily indicate danger; rather, it reflects that the substance may not meet the specific criteria for self-affirmed GRAS status or has not been petitioned for formal FDA review.

Toxicological data for this specific compound in peer-reviewed literature is limited. Related compounds and structurally similar esters have generally demonstrated low toxicity profiles in animal studies, though specific long-term safety data for 1,3-nonanediol Acetate may be proprietary or incomplete in the public domain.

In the United States, 1,3-nonanediol Acetate is not listed as a GRAS substance, which means its use in food products would require either:

1. A Food Additive Petition (FAP) submitted to the FDA for approval, or

2. Compliance with existing regulations if the substance falls under an approved category

The European Union's approach to flavoring substances is more stringent. While specific status information for this compound under EFSA regulations requires direct consultation with the Union List of Flavouring Substances, many synthetic esters undergo rigorous evaluation before approval in European food products.

Manufacturers intending to use this additive in food products should verify current regulatory compliance, as requirements may vary by country and intended application.

Publicly available peer-reviewed studies specifically examining 1,3-nonanediol Acetate are limited. Research on structurally related nonanediol derivatives and acetate esters suggests generally low oral toxicity in animal models, though specific absorption, distribution, metabolism, and excretion (ADME) data for this compound is not readily available in open literature.

The flavor and fragrance industry has historically relied on structural analogy and QSAR (Quantitative Structure-Activity Relationship) modeling for similar compounds when comprehensive toxicological data is unavailable. Such assessments typically suggest that short-chain aliphatic esters present minimal systemic toxicity at food flavoring use levels.

Additional safety data would be beneficial to establish comprehensive understanding of this additive's safety profile, particularly long-term exposure studies and metabolism studies in relevant species.
