| Summary: | The present invention relates to pump sprays, pump foams and leave-on hair treatment compositions all of which are free from propellant gas and comprise anionic and cationic polymers. U.S. Pat. No. 4,240,450 discloses mixtures and processes for treating keratin materials with polymers. The mixtures comprise an anionic and a cationic polymer. In many of the known mixtures this results in problems, in that the polymers are precipitated as solids in the mixtures. This necessitates a special application method. The known mixtures are intended in particular for what are known as rinse-off products, i.e. compositions, such as shampoos, which are applied and then washed off again. As compositions which remain on the hair only lotions are mentioned in column 51. Compositions which are free from propellant gas and are sprayed onto the hair are not disclosed. A host of very widely differing compounds are mentioned as possible polymers.
Hair treatment compositions in the form of pump sprays and pump foams that are free from propellant gases comprise at least one cationic and at least one anionic polymer having methacrylic and ethyl units. |
