Abstract
Abstract A packaged, self-heating neutralizing composition for use in the second stage of a permanent waving operation comprises a first component selected from a water-soluble sulfite, bisulfite, metabisulfite or thiourea stored in one compartment of a twocompartment package and a second component comprising H2O2 separately stored in the second compartment of said twocompartment package. Just before use, the said components are mixed together with an accompanying evolution of sensible heat. The resulting mixture contains free H2O2 in amounts of about 0.53 percent by weight of the composition.
