When selecting plasticizers for demanding applications, particularly in cosmetics and food contact materials, distinguishing between similar citrate esters is crucial. Tributyl Citrate (TBC) and Acetyl Tributyl Citrate (ATBC) are often considered, each offering unique advantages. As a leading manufacturer and supplier of citrate esters, we provide insights to help procurement managers and formulators make informed decisions. While both are excellent non-phthalate plasticizers, understanding their subtle differences is key.

Tributyl Citrate (TBC), CAS No. 77-94-1, is a direct ester of citric acid and butanol. It is valued for its good plasticizing efficiency, low toxicity, and relatively low cost, making it a strong contender for general-purpose plasticization in PVC, coatings, and even some cosmetic applications like nail polish. As a TBC manufacturer, we ensure high purity and stable pricing for this versatile compound.

Acetyl Tributyl Citrate (ATBC) is derived from TBC through an acetylation process. This modification results in a compound with even lower volatility, higher hydrolytic stability, and often a more favorable profile for extremely sensitive applications, including infant care products and medical devices. ATBC tends to be slightly more expensive due to the additional manufacturing step. For businesses looking to buy ATBC, it’s important to recognize its enhanced performance characteristics for specialized needs.

The choice between TBC and ATBC often hinges on the specific application requirements and budget constraints. For instance, if a formulator needs a highly efficient plasticizer for general PVC applications where extreme low volatility isn't critical, TBC might be the more cost-effective solution. However, for applications demanding the utmost in safety, such as baby pacifiers or specialized medical tubing, ATBC often takes precedence. As a supplier of both, we can guide you based on your project’s specific needs.

When sourcing either TBC or ATBC, partnering with a reputable manufacturer in China offers significant advantages in terms of cost and volume. We are committed to providing both Tributyl Citrate and Acetyl Tributyl Citrate with consistent quality and competitive pricing. We encourage you to request quotes for both products and discuss your specific application requirements with our technical team. Our goal is to be your go-to supplier for high-quality citrate ester plasticizers, ensuring your products meet performance and safety standards.
