Les produits capillaires pour la fixation des cheveux les plus répandus sur le marché de la cosmétique sont des compositions à pulvériser en aérosol ou en flacon pompe tels que les laques, les sprays ou les mousses, essentiellement constituées d'une solution le plus souvent alcoolique ou hydroalcoolique et d'un polymère filmogène soluble dans l'eau ou dans l'alcool, en mélange avec divers adjuvants cosmétiques.The most common hair products for fixing the hair on the cosmetics market are aerosol or pump spray compositions such as hairsprays, sprays or mousses, essentially consisting of a solution, most often alcoholic or hydroalcoholic and a film-forming polymer soluble in water or in alcohol, mixed with various cosmetic adjuvants.
De nombreuses compositions de maintien et/ou de mise en forme des cheveux de l'art antérieur, qui contiennent dans leur formulation des polymères de coiffage, peuvent altérer les propriétés cosmétiques des cheveux.

EXEMPLE (Comparatif en flacon pompe):EXAMPLE (Comparative in pump bottle):
On a préparé les deux compositions de coiffage suivantes A et B. La composition A comprend un polymère filmogène classique, tandis que la composition B comprend du poly-4-hydroxystyrène. Les formulations sont résumées dans le tableau 1 ci-après. Tableau 1The following two styling compositions A and B were prepared. Composition A comprises a conventional film-forming polymer, while composition B comprises poly-4-hydroxystyrene. The formulations are summarized in Table 1 below. Table 1
On réalise un test sensoriel en mettant en œuvre le protocole ci-après.A sensory test is carried out by implementing the protocol below.
On vaporise par demie tête les compositions A et B conditionnées dans un équipement flacon pompe sur un panel de 7 modèles. Après séchage, on obtient un pouvoir laquant identique et on évalue la facilité de démêlage, la douceur et le toucher pour chacune de ces compositions. Pour chacun des 3 critères, l'expérimentateur attribue une note entre 0 et 50 et on calcule la moyenne sur le panel. Cette moyenne est rapportée dans le tableau 2 ci-après.Half a head is sprayed with compositions A and B packaged in pump bottle equipment on a panel of 7 models. After drying, an identical lacquering power is obtained and the ease of disentangling, the softness and the feel for each of these compositions is evaluated. For each of the 3 criteria, the experimenter assigns a score between 0 and 50 and the average is calculated on the panel. This average is reported in Table 2 below.
Tableau 2Table 2
Par conséquent, l'association selon l'invention présente un avantage significatif en démêlage, en douceur et en toucher. On remarque que la composition conforme à l'invention procure une nette amélioration en ce qui concerne la facilité de démêlage. Consequently, the combination according to the invention has a significant advantage in disentangling, gently and in touch. It is noted that the composition according to the invention provides a marked improvement with regard to the ease of disentangling.
