A solid, water-soluble complex comprising:

Surfactant co-clathrates

Surfactant clathrates and agricultural chemical formulations thereof

Stable, concentrated non-aqueous suspensions of water-soluble solids are prepared by using a water soluble active compound comprising water hydratable polysaccharides, biocides, fertilizers and mixtures thereof dispersed in water-miscible organic liquid carriers, preferably lower alkadiols in conjunction with a specific three component surfactant system, i.e., a system comprising a nonionic polymeric viscosity modifier surfactant; an anionic surfactant; and a nonionic surfactant having a bulky hydrophobic substituent group.

Non-aqueous suspension concentrates of highly water-soluble solids

Stable, concentrated nonaqueous suspensions of water-soluble solids are prepared by using water-miscible organic liquid carriers, preferably lower alkadiols in conjunction with a specific three component surfactant system, i.e., a system comprising a nonionic polymeric viscosity improver surfactant; an anionic surfactant; and a nonionic surfactant having a bulky hydrophobic substituent group.
