Abstract

The use of phase inversion temperature emulsions containing a non-aqueous phase of (a) one or more C8-22 fatty acid alkyl esters, (b) one or more C8-22 fatty alcohols, (c) one or more C8-22 alcohol polyglycol ethers, and (d) one or more C8-22 fatty acid partial glycerides, and an aqueous phase; as softening formulations for substrates such as papers, nonwovens, tissues and cloths is described.
