Description

1,3-Butanediol Adipate Polymer, Mixed Esters With Lauric, Myristic, Palmitic And Stearic Acid is a synthetic polyester plasticizer and emollient derived from 1,3-butanediol, adipic acid, and a blend of medium to long-chain fatty acids. This compound matters for its ability to impart flexibility, smooth texture, and compatibility in polymer systems while offering a favorable toxicological profile compared to traditional phthalates. It is primarily needed by manufacturers in the plastics, personal care, and specialty coatings industries seeking high-performance, versatile additives.

Application

• Primary Plasticizer for polyvinyl chloride (PVC), polyurethane (PU), and other synthetic resins to enhance flexibility and low-temperature performance.
• Polymer Modifier in adhesives, sealants, and elastomers to adjust viscosity, improve processability, and increase elongation.
• Film Former & Emollient in cosmetic and personal care formulations such as creams, lotions, and sunscreens for skin conditioning.
• Lubricant and Processing Aid in the manufacturing of engineering plastics and composite materials.
• Coalescing Agent & Plasticizer in specialty paints, inks, and industrial coatings to improve film formation and durability.
• Functional Fluid base or additive in synthetic lubricants and hydraulic fluids.

Quality Control

Our 1,3-Butanediol Adipate Polymer is produced under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including acid value, hydroxyl value, saponification value, viscosity, and color to ensure consistent performance and purity. Certificates of Analysis (COA) documenting full specifications are available upon request. Production can adhere to ISO 9001 standards, and relevant portions of the composition may comply with indirect food contact and cosmetic ingredient regulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from strong acids, organic solvents, and strong oxidizing agents. As the product may be susceptible to oxidation over prolonged periods, storing under an inert atmosphere (e.g., nitrogen) is recommended for bulk quantities to maximize shelf life.
