A method for identifying hair conditioner-resistant hair-binding peptides is described. The hair conditioner-resistant hair-binding peptides bind strongly to hair from a hair conditioner matrix and are stable therein. Peptide-based benefit agents, such as hair conditioners and hair colorants, based on the hair conditioner-resistant hair binding peptides are described. The peptide- based hair conditioners and hair colorants consist of a hair conditioner- resistant hair-binding peptide coupled to a hair conditioning agent or a coloring agent, either directly or through an optional spacer. Hair care and hair coloring product compositions comprising these peptide-based hair conditioners and colorants are also described.
L'invention concerne un procédé visant à identifier des peptides se liant aux cheveux et qui résistent à un revitalisant capillaire. Lesdits peptides, stables dans une matrice de revitalisant capillaire, se lient fortement aux cheveux. L'invention concerne des agents bénéfiques à base de peptides, tels que des revitalisants et colorants capillaires, qui contiennent les peptides de l'invention. Ces revitalisants et colorants capillaires se composent du peptide de l'invention couplé à un agent revitalisant capillaire ou à un colorant capillaire, soit directement, soit par l'intermédiaire d'un élément d'espacement facultatif. L'invention concerne aussi des compositions de produits de soin et de coloration capillaires qui renferment les revitalisants et colorants capillaires contenant lesdits peptides.
