Beschreibung
Zusammenfassung:	The present invention relates to a novel multi-block copolymer comprising more than three blocks, including at least a block A and a block B, wherein the block A is a cationic block and the block B is a nonionic block. The invention more specifically relates to a rinse-off personal care composition comprising the multi-block copolymer. The invention also relates to a process for the preparation of the multi-block copolymer. The invention still relates to a method for obtaining improved conditioning performance and enhanced deposition of benefit agents onto a surface by utilizing the multi-block copolymer. La présente invention concerne un nouveau copolymère à blocs multiples comprenant plus de trois blocs, comprenant au moins un bloc A et un bloc B, le bloc A étant un bloc cationique et le bloc B étant un bloc non ionique. L'invention concerne également une composition de soins personnels à rincer, comprenant le copolymère à blocs multiples. L'invention concerne également un procédé de préparation du copolymère à blocs multiples. L'invention concerne également un procédé permettant d'obtenir des performances améliorées de conditionnement et un dépôt amélioré d'agents bénéfiques sur une surface par utilisation du copolymère à blocs multiples.
