The present invention comprises hair care compositions such as mousses, tonics, lotions, hairsprays, and gels, which provide style retention and improved conditioned haid feel benefits. Said compositions achieve the improved conditioning and hair feel benefits by emulsifying a silicone conditioning agent containing relatively high levels of silicone gum. These emulsions are incorporated into hair care compositions which additionally contain a hair setting polymer. More specifically, provided is a hair care composition that comprises: (a) from about 0.1 % to about 75 %, by weight of the composition, of an emulsified silicone conditioning agent: (i) from about 20 % to 100 %, by weight of the silicone conditioning agent, of a nonvolatile silicone gum; (ii) from 0 % to about 80 %, by weight of the silicone conditioning agent, of a nonvolatile silicone fluid, having a viscosity at 25°C of less than 1,000,000 centistokes; (b) from about 0.1 % to about 25 %, by weight of the composition, of an emulsifying agent for said silicone conditioning agent; (c) from about 0.1 % to about 25 %, by weight of the composition, of a hair setting polymer; (d) from 0 % to about 25 %, by weight of the composition, of an additional cationic cosmetic agent; and (e) from about 24.8 % to about 99.7 %, by weight of the composition, of an aqueous carrier; wherein the hair care compositions are essentially free of volatile solvents and contain no more than about 4.0 %, by weight of the composition, of anionic surfactants; and said composition must contain at least 0.1 % of a cationic cosmetic agent.
La présente invention concerne des produits capillaires sous forme notamment de mousses, de tonifiants, de lotions, de sprays et de gels, qui ont un effet coiffant et donnent aux cheveux conditionnés une plus grande souplesse. Lesdites compositions procurent ces effets grâce à un conditionneur aux silicones en émulsion comportant une proportion relativement élevée de gomme de silicones. Ces émulsions sont incorporées dans les produits capillaires qui contiennent en outre un polymère fixant. De façon plus spécifique, l'invention concerne un produit capillaire dont la formulation pondérale est: (a) d'environ 0,1 % à 75 % d'un conditionneur à base d'émulsion de silicones; (i) d'environ 20 % à 100 % d'une gomme de silicones non volatils dans le conditionneur à base d'émulsion de silicones; (ii) d'environ 0 % à 80 % d'un fluide de silicones non volatils ayant une viscosité inférieure à 1.000.000 centistokes à 25 ~C; (b) d'environ 0,1 % à 25 % d'un émulsifiant destiné audit conditionneur à base de silicones; (c) d'environ 0,1 à 25 % d'un polymère fixant; (d) d'environ 0 % à 25 % d'un additif cosmétique cationique; et (e) d'environ 24,5 à 99,7 % d'un support aqueux. Selon cette formulation, les produits capillaires sont essentiellement exempts de solvants volatils et contiennent moins d'environ 4 % (en formulation pondérale) d'agents tensioactifs anioniques. Le dit produit capillaire doit contenir au moins 0,1 % d'un agent cosmétique cationique.
