Introduced: September 1968

Description

C11D covers the composition and manufacture of detergents and soaps, including formulated detergent products containing surfactants, builders, and other functional ingredients, as well as traditional soap production from fats and oils. It encompasses single-substance detergents, synthetic detergent compositions, soap manufacturing processes, resin-based soaps, and glycerol recovery as a by-product of soap-making. The subclass excludes detergency mechanisms and wash processes themselves (covered under C11C for oils and fats processing), as well as cosmetic and pharmaceutical preparations that may contain detergent ingredients (classified separately).

Of 11 combined children, 10 exist in both systems.
