colloidally stable

https://doi.org/10.1351/goldbook.C01176
Particles which do not aggregate at a significant rate: the precise connotation depends on the type of aggregation under consideration. For example, a concentrated paint is called
stable
by some people because oil and pigment do not separate out at a measurable rate, and
unstable
by others because the pigment particles aggregate into a continuous
network
