Description

Gum Mastic CAS NO 61789-92-2 is a natural resin obtained from the Pistacia lentiscus tree, valued for its unique adhesive, film-forming, and protective properties. This versatile material serves as a crucial natural binder and stabilizer in high-value formulations where synthetic alternatives are undesirable. It is essential for manufacturers in the food, pharmaceutical, cosmetic, and fine art conservation industries seeking natural, compliant ingredients.

Application

• Food & Beverage Industry: Used as a natural glazing agent, stabilizer, and texturizer in chewing gum, confectionery coatings, and beverage emulsions.
• Pharmaceuticals: Employed as a binding agent in tablet formulations and as a component in protective coatings for pills and lozenges.
• Cosmetics & Personal Care: Functions as a film-forming agent in hair sprays, mascara, and skincare products, providing hold and barrier properties.
• Fine Art & Conservation: A traditional and respected material used as a varnish and protective coating for paintings and historical artifacts.
• Adhesives & Sealants: Acts as a key ingredient in specialty adhesives, particularly in dental cements and niche industrial applications requiring natural resins.
• Paints & Coatings: Utilized in high-grade varnishes and lacquers to enhance gloss, durability, and drying characteristics.

Quality Control

Our Gum Mastic is sourced and processed under strict quality protocols to ensure consistency and purity for industrial applications. We offer grades suitable for food, cosmetic, and technical use, with processing aligned to relevant guidelines. Certificates of Analysis (COA) documenting key parameters such as solubility, acid value, and ash content are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Keep away from strong heat sources and incompatible materials. The resin is light-sensitive (store away from light) and should be handled to minimize prolonged exposure to air and moisture.
