  • effective amount is meant an amount sufficient to provide the hair volume and style benefits desired considering the length and texture of the hair.
  • liquid hair cosmetic compositions in the form of hairspray compositions suitable for pump spray dispensers and which are representative of the present invention:
  • the balance contains ethanol and any optional ingredients such as plasticizers, perfume and surfactants.
  • the hairspray formulations are prepared by adding the polymer directly to the ethanol.
  • a magnetic or air driven stirrer is used to mix the ingredients until the polymer is dissolved, typically about 1 to 2 hours.
  • the neutralizing agent is then added and mixed into the premix.
  • the optional ingredients and water, as may be applicable, are mixed into the composition.
  • compositions have excellent clarity and when applied to the hair impart excellent hair feel and good style retention properties.
  • liquid hair cosmetic compositions in the form of hairspray concentrate compositions suitable for aerosol dispensers and which are representative of the present invention:
  • the balance can contain ethanol and optional ingredients such as plasticizers, perfumes and surfactants.
  • the compositions are prepared as in Examples I- VI.
  • the concentrates are packaged in conventional aerosol spray cans and are charged with a conventional liquifiable propellant, such as CAP 80 (propane/butane) (RTM) at a propellant:concentrate weight ratio of 23:77.
  • compositions have excellent clarity and long term and stressed temperature stability characteristics and when applied to the hair impart excellent hair feel and good style retention properties.

Abstract

L'invention concerne une composition cosmétique liquide pour cheveux comprenant: a) d'environ 0,1 à environ 10 % en poids (base acide) d'un copolymère d'acide polycarboxylique siliconé pour la tenue des cheveux, ayant un squelette de polymère vinylique sur lequel on a greffé un macromère siliconé d'un poids moléculaire moyen se situant dans une plage d'environ 1 000 à 50 000; b) d'environ 0,01 à environ 10 % en poids d'une résine pour la tenue des cheveux ne contenant pas de silicones; et c) le pourcentage restant comprenant un excipient approprié pour les cheveux. De tels produits cosmétiques liquides pour cheveux démontrent d'excellentes qualités de tenue de la chevelure et de toucher; ils facilitent en outre le brossage et possèdent une transparence améliorée
