Didodecyl succinate is widely used as a plasticizer in the production of polymers and resins, enhancing their flexibility and durability. It is particularly effective in applications involving polyvinyl chloride (PVC) and other thermoplastic materials, where it improves processing and end-product performance. Additionally, it serves as a lubricant in various industrial processes, reducing friction and wear in machinery. Its compatibility with organic materials also makes it suitable for use in coatings, adhesives, and sealants, where it contributes to improved adhesion and stability. In personal care products, it is utilized as an emollient, providing a smooth and soft texture in formulations like creams and lotions. Its non-toxic and stable nature further extends its use in food-contact materials, ensuring safety in packaging applications.
