Solids dispersions which can be easily distributed in hydrophobic and hydrophilic media and are stable to flocculation, and their use

Claim 1

A dispersion of a solid having acidic groups on its surface in a liquid medium, said solid constituting 5 to 80% by weight of said dispersion, and said medium consisting essentially of (a) a fatty amine constituting 0.2 to 8% by weight of said dispersion and having the formula ##STR2## wherein R 1 is an aliphatic, araliphatic or cycloaliphatic radical, having a chain of from ten to twenty-five carbon atoms containing up to three carbon-carbon double bonds or said chain substituted by hydroxy, and wherein R 2 and R 3 , which are the same or different, is each hydrogen or an aliphatic, araliphatic or cycloaliphatic radical of from one to thirty carbon atoms or is a group of the formula --(CH.sub.2).sub.n --OH or --(CH.sub.2).sub.n --NH.sub.2 in which n is from one to six with the proviso that at least one or two of R 1 , R 2 and R 3 is an alkyl or alkenyl residue of from ten to twenty-five carbon atoms; (b) a nonionic surfactant selected from the group consisting of an adduct of 5 to 20 moles of ethylene oxide onto an alkylphenol and of an adduct of 5 to 20 moles of ethylene oxide onto a fatty alcohol, or a mixture thereof, or an anionic surfactant selected from the group consisting of an alkylsulfate, alkylsulfonate and alkylbenzene sulfonate, or a mixture thereof, or a combination of said nonionic and anionic surfactants, these surfactants constituting 3 to 25% by weight of said dispersion and having one or more aliphatic chains with a total of more than 5 carbon atoms and (c) a water miscible organic solvent constituting 10 to 85% by weight of said dispersion.
