At the commercial level, CAPB is available in two grades: 35%±2 and 45%±2 grade. Understanding how active matter concentration affects CAPB pricing helps manufacturers evaluate cost-per-active-unit economics when choosing between 30%, 35%, and 45% grades. In general, for 35% grade, the active matter is 30%±2, and for 45% grade, the active matter is 38%±2.
These grades provide versatile solutions for various applications in industries such as personal care and cleaning products.
