DEFINITION

Classification: 516/FOR.100

Foreign art collections including compositions which are colloid systems; processes of making or of resolving (breaking) the same; gels, coagulates; potential dispersands (compositions containing in each case a material adapted to be colloidally dispersed and a substance for colloidally dispersing or stabilizing a colloidal dispersion of the same); processes of using colloid systems; compositions specialized and designed for use in, or peculiar to, such systems, gels, coagulates, dispersands, or processes, including wetting agents, substances for stabilizing, resolving, or inhibiting formation of such systems, and for dispersing materials.
