COPALS, MANILA

CAS: 9000-42-4

COPALS, MANILA is a natural resin listed by the U.S. FDA as a diluent in color additive mixtures for food use exempt from certification under 21 CFR 73.1.

What It Is

COPALS, MANILA is a natural resinous substance identified by the CAS number 9000-42-4 and listed in the U.S. FDA "Substances Added to Food" inventory for its use in color additive mixtures for food. It is sometimes referred to by other names including COPAL, MANILA COPALS, and MANILA MANILA COPAL. Resins of this type are traditionally derived from the hardened sap of certain tropical trees, historically collected and processed for a variety of applications. In the context of food regulation, COPALS, MANILA is recognized for its role as a diluent component in mixtures intended to modify or stabilize color additive formulations. The term "diluent" in food additive regulation means a material that is not itself a color additive but is included in a mixture to facilitate the use of the color additive in food products under defined regulatory conditions. Its listing under 21 CFR 73.1 indicates the substance may be used in color additive mixtures exempt from certification when other components of the mixture have been certified or meet conditions of exemption, consistent with regulatory requirements.

How It Is Made

The production of natural resins like COPALS, MANILA typically begins with the collection of exuded resinous sap from trees such as those in the family Araucariaceae in parts of Southeast Asia, particularly the Philippines. The raw resin is collected from the tree bark and allowed to harden. After collection, the resin may be cleaned mechanically to remove debris and impurities. Further purification can involve heating and filtration to remove volatile components or suspended solids, depending on the intended technical application. Unlike synthetic additives, natural resins do not have a single defined chemical formula but are complex mixtures of terpenoid and related compounds. For regulatory purposes, such materials are characterized by their botanical source, physical properties, and suitability for use as specified in relevant regulations. This general description reflects common industry practice for resinous materials and their preparation rather than detailed proprietary methods. Manufacturers producing food-grade diluents must ensure the purity of their materials is consistent with defined regulatory use conditions, even if specific analytical specifications are not set out in a regulation.

Why It Is Used In Food

COPALS, MANILA is used as a technical component in color additive mixtures for food applications. Color additives are substances that impart color to food products. In regulatory terms, certain natural resins may be included as diluents to help disperse, stabilize, or deliver the colorant in food processing. A diluent is not itself a direct coloring agent but can assist in formulating a mixture that delivers the desired color effect in a food product. Inclusion of diluents like COPALS, MANILA in a color additive mixture must meet the specific regulatory conditions outlined in the Code of Federal Regulations to ensure that the finished mixture is safe for the intended use. This usage is not the same as adding a primary color additive; rather, it supports the physical and functional aspects of color formulation, such as adjusting viscosity, aiding mixing, or improving the performance of the color additive under specific processing conditions.

Adi Example Calculation

Because there is no established acceptable daily intake (ADI) for COPALS, MANILA documented in the referenced authoritative resources, it is not possible to provide a meaningful illustrative calculation using numeric intake limits. ADIs are typically established when toxicological data support quantitative thresholds for lifetime exposure. In the absence of such an established ADI, any example calculation would be speculative and is therefore omitted. Instead, this section highlights that ADIs require an authoritative numeric value as a basis, which is not available for this substance in the current regulatory record.

Safety And Health Research

Regulatory bodies such as the U.S. Food and Drug Administration evaluate substances for their intended use in food, including color additives and their components. The listing of COPALS, MANILA as a diluent in color additive mixtures exempt from certification is based on the regulatory framework that defines such uses and does not by itself constitute an assessment of toxicological endpoints such as chronic toxicity or reproductive effects. Scientific research specific to COPALS, MANILA’s health effects in humans or animals has not been identified in the available authoritative resources. Color additive evaluations generally involve considerations of exposure, chemical identity, and toxicological data to determine safety under conditions of intended use. Without specific safety evaluations from regulators such as EFSA or JECFA for this substance, comprehensive hazard data are not established in the public regulatory record. The use of any additive component, including diluents, is subject to regulatory controls that aim to ensure that the resulting food product is safe when used as intended.

Regulatory Status Worldwide

In the United States, COPALS, MANILA is listed in the FDA "Substances Added to Food" inventory with a reference to 21 CFR 73.1, which pertains to diluents in color additive mixtures for food use that are exempt from certification. This regulatory listing means that the substance may be included in color additive mixtures for food use under specific conditions but is not itself a certified color additive. For a diluent to be used under this provision, the mixture's other components must be certified except when regulatory conditions for exemption are met. FDA's color additive regulations require that any substance used as a color additive or as part of a color additive mixture must comply with relevant sections of Title 21 of the Code of Federal Regulations. Outside of the U.S., regulatory frameworks vary by jurisdiction. Many countries maintain their own lists of permitted food additives and colorants. In the absence of specific evaluations or listings by other authorities such as the European Food Safety Authority (EFSA) or the Joint FAO/WHO Expert Committee on Food Additives (JECFA), COPALS, MANILA’s status would need to be confirmed under the relevant national or regional regulations. As of now, authoritative regulatory listings in other major jurisdictions have not been identified in the available evidence.

Taste And Functional Properties

Natural resins such as COPALS, MANILA do not contribute a defined taste profile to foods because they are typically used at low levels in technical mixtures rather than for flavor. Resins themselves are complex mixtures of high-molecular-weight organic compounds, many of which are not water soluble. In functional terms, the substance can act as a diluent in a color additive mixture, helping to disperse the colorant evenly and maintain mixture stability during processing, storage, or application. These functional properties depend on the resin's physical characteristics, such as viscosity and compatibility with other ingredients in the mixture. Because it is used in colorant systems, its sensory impact on foods when used as permitted is considered negligible. The use of resins in color formulations is a specialized application distinct from flavoring or nutritive roles in food systems.

Acceptable Daily Intake Explained

An acceptable daily intake (ADI) is a concept used by regulators to indicate the amount of a substance that can be consumed daily over a lifetime without appreciable health risk, based on available toxicological data and significant safety margins. For well-studied food additives, ADIs are established following evaluations by expert committees such as JECFA or EFSA. In the case of COPALS, MANILA, no specific ADI has been publicly documented by major regulatory bodies in the evidence available. This absence of a documented ADI reflects the fact that the substance is recognized in a regulatory context for a specific technical use rather than as a directly consumed additive with defined intake limits. As a result, an ADI is not provided, and any numeric intake thresholds are not established. The explanation here is intended to clarify the general concept of an ADI and why it may not be defined for every substance that appears in a regulatory listing.

Comparison With Similar Additives

COPALS, MANILA can be compared with other diluents or auxiliary substances used in color additive mixtures such as natural gums or fatty acid esters that serve to disperse or stabilize the colorant. Unlike direct color additives that impart a visible hue to foods, diluents are chosen for their physical and functional properties rather than their chromatic contribution. For example, a natural gum might be used to increase viscosity and help suspend color particles, while a resin like COPALS, MANILA may provide compatibility with specific color systems. In contrast, synthetic colorants used in foods have well-defined regulatory listings, specifications, and often established ADIs. Understanding these differences helps clarify the technical role of diluents versus primary colorants and the distinct regulatory considerations that apply to each category.

Common Food Applications Narrative

In food manufacturing, color additive mixtures are created to impart or enhance the appearance of a wide range of products. COPALS, MANILA, when used as a diluent, supports the formulation of these mixtures without directly coloring the food itself. Examples of where color additive mixtures might be found include confections, bakery items, beverages, and snack products that rely on color for consumer appeal and product consistency. In practice, COPALS, MANILA would be part of a larger mixture that includes a certified color additive or other approved components necessary to achieve the target hue. It is important to note that it is the color additive in the mixture that imparts visible color to the food, while the diluent assists in the formulation and handling of that additive. The use of diluents like COPALS, MANILA is controlled under regulatory frameworks to ensure that any food products formulated with these mixtures meet safety and labeling requirements. Food producers considering color additive mixtures must ensure compliance with all applicable regulations and good manufacturing practices to maintain product quality and regulatory conformity.
