Definitions

  • the present invention relates to a hair care composition in the form of a gel-cream comprising a particular association of at least one emulsifying polymer and at least one thickener chosen from acrylic and/or methacrylic acid polymers or copolymers, an oil phase containing at least one oil and at least one fatty alcohol, and at least one neutralizing agent.
  • the composition according to the present invention is useful for volume and frizz control and curl definition of the hair, particularly curly and wavy hair.
  • the present invention also relates to a method for styling the hair, the use of said hair care composition, and a method of imparting to hair one or more of volume control, shape, curl definition and frizz control.
  • the quality, condition and appearance of hair can be adversely affected by many factors, such as excessive use of hair dryer and flat iron, lack of moisture, mechanical or chemical treatments, such as brushing, combing, dyeing, bleaching, permanent-waving and/or relaxing, and humid weather.
  • the hair can thus be damaged by these various factors and may over time become dry, frizzy, coarse, brittle or dull, in particular in fragile areas, and more particularly at the ends.
  • the types of hair that suffer most from frizz are curly and wavy hair, which have a greater tendency to dryness. As the humidity in the air increases, the hair shafts become more electric and repel each other, resulting in frizz.
  • curly and wavy hair can also suffer from non-ideal volume and lack of shape, mainly due to the physical characteristics of the hair shafts and excessive dryness. Further, hair health loss caused by moisture deficiency or excess of chemical treatment can make the hair porous and consequently with less discipline along the day. As a result, hair becomes unmanageable and undisciplined, and loses its natural shape and/or curl definition.
  • hair cosmetic products such as those products designed to provide hair care benefits of manageability, frizz control, volume reduction, and improved quality of the hair fiber and/or to change the appearance, shape or configuration of hair, as well as have textures and consistencies that are desirable and appealing to consumers.
  • hair cosmetic products are conditioning shampoos, conditioners, masks, serum, hair repair products, and other hair treatment products.
  • Such products may afford the hair good cosmetic properties; however, users sometimes feel that their hair becomes lank, flat or weighed down by the product and/or becomes greasy. When the product is too thick, it may also prove to be difficult to distribute it evenly when applied to the hair.
  • the introduction of certain ingredients can pose formulation challenges; for example, the products can become sticky or tacky upon application and once dry, may become stiff and/or "crunchy" (i.e. the film is hard and brittle resulting in a crunching feel or sound when the hair is touched), which is undesirable for many consumers. Also, the performance of such products may still not be optimal, especially from the point of view of the efficacy in reducing the frizziness, the ease of application of the composition, the ability to deliver other active materials to hair, reduce/prevent the damaged feel or look of hair, especially after or during a hair chemical treatment and the final cosmeticity and feel of the treated hair.
  • compositions which are suitable for the cosmetics field, and which are able to effectively provide adequate visual sleekness of the hair; good feel and conditioned feel of the hair, and in particular of wet hair; control, or even elimination, of frizziness, and also control or reduction of the volume and of the apparent mass of the head of hair, the said compositions thus being most particularly suitable for curly and/or voluminous hair.
  • One aim of the present invention is to provide a hair care composition, such as a composition for styling or shaping the hair, for volume and frizz control and curl definition or curl regularity of the hair, in particular curly and wavy hair.
  • Another aim of the present invention is to provide a light feel and easy spreadable composition for treating and/or shaping the hair.
  • the present invention relates to a hair care composition in the form of a gel-cream comprising a particular association of at least one emulsifying polymer and at least one thickener chosen from acrylic and/or methacrylic acid polymers or copolymers, an oil phase containing at least one oil and at least one fatty alcohol, and at least one neutralizing agent.
