Surface area of metallic stearate excipients (zinc and calcium stearate) – a case study
Zinc and calcium stearate (metal soaps) are among the most commonly used stearates across diverse industries. Surface area, as characterized with the Anton Paar Nova 600 and Kaomi for Nova CFR Part 11 software, confirms manufacturing quality and specification values in controlled, regulated processes.
The versatility of zinc and calcium stearates in various industries has created a steadily growing market that is expected to be valued at $4.9 billion by 2028. This market growth compels industries – especially highly-regulated ones that must comply with governmental regulations such as those imposed by the United States Food and Drug Administration (US FDA) – to evaluate (characterize) and manufacture these raw materials quickly, efficiently, and transparently.
Gas adsorption is a trusted technique that can provide specific surface area of the stearates. The Anton Paar Nova Series can provide this and other information, such as homogeneity of the evaluated materials, rapidly, reliably, and reproducibly.
