Preservatives
Designed to ensure product integrity and extend shelf life, our Preservatives include a specialized selection of pharmaceutical-grade antimicrobials, antioxidants, and stabilizers. These compounds—such as parabens, sorbates, and sulfites—are essential in preventing microbial growth, oxidation, and degradation in both topical and ingestible formulations. Manufactured under strict GMP conditions, each preservative meets global pharmacopeial standards, supporting consistency and compliance in drug, cosmetic, and nutritional product development.
At Sigma Corp in Cochabamba, Bolivia, preservative-grade materials are produced and processed with the same dedication to safety, traceability, and quality that defines all of our GMP-certified operations. Our preservative portfolio spans essential actives like Potassium Sorbate and Benzyl Alcohol to specialized compounds such as Thimerosal, Resorcinol, and Butylated Hydroxyanisole. These ingredients are supported by rigorous testing, precise documentation, and an integrated quality assurance system. Whether used in injectable formulations, personal care products, or stability-sensitive APIs, Sigma’s preservative offerings reflect our commitment to controlled manufacturing, regulatory alignment, and international distribution readiness.
