Description

Calendic Acid is a conjugated octadecatrienoic fatty acid primarily derived from calendula oil. This unique compound matters for its role as a valuable bio-based intermediate and a precursor for specialty polymers and coatings. It is needed by manufacturers in the polymer, cosmetic, and specialty chemical industries seeking sustainable, plant-derived raw materials with specific reactive properties.

Application

• Polymer & Resin Modification: Used as a reactive diluent or cross-linking agent in the synthesis of alkyd resins, polyesters, and other specialty polymers to enhance flexibility and drying properties.
• Cosmetic & Personal Care Ingredients: Serves as a base material for synthesizing esters and other derivatives used in skincare formulations for their emollient properties.
• Lubricant & Fuel Additives: Investigated as a precursor for bio-based lubricants or as a component in fuel additive formulations.
• Chemical Intermediate: Acts as a key starting material in organic synthesis for producing conjugated fatty acid derivatives used in research and industrial applications.
• Coatings & Inks: Utilized in the development of environmentally friendly, high-performance coatings and printing inks that require rapid curing.

Quality Control

Our Calendic Acid is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, identity, and impurity profiles. For specific regulatory or application requirements, please contact our technical support team.

Storage

Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C). Keep the container in a cool, dry, and well-ventilated area away from heat and ignition sources.
