What is Rosin, Partially Dimerized, Calcium Salt?
Rosin, Partially Dimerized, Calcium Salt (CAS Number: 977051-86-7) is a modified form of natural rosin, a resinous substance obtained from pine trees. In this formulation, rosin molecules have undergone partial dimerization—a chemical process where two rosin molecules bond together—and the resulting compound has been complexed with calcium. This creates a calcium salt derivative with altered chemical and physical properties compared to unmodified rosin.
Common Uses
Rosin, Partially Dimerized, Calcium Salt functions as a surface-finishing agent in food applications. Surface-finishing agents are used to coat food products, providing protective barriers that can improve appearance, preserve moisture, reduce oxidation, and extend shelf life. These agents are typically applied to foods such as citrus fruits, apples, and other produce to create a glossy finish and protective layer. The modification of the rosin structure in this formulation is intended to improve its performance characteristics compared to traditional rosin-based coatings.
Safety Assessment
According to FDA records, there have been zero reported adverse events associated with Rosin, Partially Dimerized, Calcium Salt and zero product recalls involving this substance. This lack of adverse event reports suggests that the substance has not been associated with consumer health complaints or safety incidents in the U.S. food supply.
The additive's safety profile is supported by the fact that it derives from rosin, a substance with a long history of use in food applications. Traditional rosin has been used in food coatings for decades. The partial dimerization and calcium complexation modify the rosin's properties but maintain a substance with known composition and characteristics.
Limited published safety data is available specifically for this partially dimerized calcium salt form. The lack of extensive scientific literature on this particular derivative reflects its specialized application rather than concerns about its safety. Substances used as surface-finishing agents typically contact only the exterior of foods and are generally recognized as low-risk in terms of systemic food safety concerns.
Regulatory Status
Rosin, Partially Dimerized, Calcium Salt has not been designated as Generally Recognized As Safe (GRAS) by the FDA. This means it does not have GRAS status, which is reserved for substances with a long history of safe use or extensive scientific evidence supporting safety. However, the absence of GRAS status does not necessarily indicate the substance is unsafe; rather, it may indicate that formal GRAS petition or approval processes have not been completed, or that the substance is used under specific regulatory frameworks or as part of approved food contact substances.
In the European Union, rosin and rosin derivatives are regulated under food contact material regulations rather than as direct food additives. The specific regulatory pathway for this partially dimerized calcium salt may vary by jurisdiction.
Key Studies
Direct peer-reviewed scientific studies specifically evaluating Rosin, Partially Dimerized, Calcium Salt are limited in available literature. Safety evaluations would typically focus on toxicological studies, migration testing from food contact surfaces, and acute/chronic exposure assessments. The chemical modification of rosin through dimerization and calcium complexation is an established industrial process, but specific safety data for this particular derivative would be found in manufacturer technical documentation or regulatory submissions rather than in open scientific literature.
Regulatory agencies typically establish safety baselines for modified rosin products based on composition analysis, food contact migration studies, and toxicological data submitted by manufacturers during approval or notification processes.
