Abstract
Ethanol soluble or dispersible polyetheramide polymers that have a percent elongation to break of less than 100%. The polymers are formed from a reaction mixture comprising at least one or more poly(alkyleneoxy)diamines and one or more diacids. The reaction mixture can optionally include one or more aliphatic diamines in addition to the one or more poly(alkyleneoxy)diamines. The polyetheramide polymers have application in personal care compositions such as hair fixative compositions, for example, hair spray formulations.
