Definitions

  • the present invention relates to hair conditioning compositions comprising an carboxylic acid/carboxylate copolymer and vinylpyrrolidone copolymer.
  • the present invention also relates to hair conditioning compositions comprising a gel matrix and a vinylpyrrolidone polymer.
  • shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components. The hair can further be left with increased levels of static upon drying which can interfere with combing and result in a condition commonly referred to as "fly-away hair", or contribute to an undesirable phenomena of "split ends", particularly for long hair.
  • Conditioning formulations can be in the form of rinse-off products or leave- on products, and can be in the form of an emulsion, cream, gel, spray, and mousse.
  • Products in the form of cream, gel, and mousse are suitable in that the consumer can easily control the amount and distribution of the product. As such, these products are particularly suitable for leave-on products.
  • a common method of providing conditioning benefit to the hair is through the use of hair conditioning agents such as cationic surfactants and polymers, silicone conditioning agents, hydrocarbon oils, and fatty alcohols.
  • hair conditioning agents such as cationic surfactants and polymers, silicone conditioning agents, hydrocarbon oils, and fatty alcohols.
  • Cationic surfactants and polymers, hydrocarbon oils and fatty alcohols are known to enhance hair shine and provide moistness, softness, and static control to the hair.
  • such components can also provide greasy or waxy feeling.
  • Silicone conditioning agents are also known to provide conditioning benefits such as smoothness and combing ease due to the low surface tension of silicone compounds.
  • silicone conditioning agents can cause dry feel or frizzy condition to the hair.
  • these conditioning agents when included in a leave-on product, they may further leave the hands with a tacky, dirty, feeling.
  • hair volume-up is not equal to fly-away hair. Fly-away hair is due to the increased level of static, and represents volume increase of only very minor amount of the hair as a whole, and is not desirable.
  • hair volume-up as used herein relates to increase of the bulk of the hair volume. Consumers having fine hair have the desire to achieve hair volume-up while controlling undesirable fly-away of the hair.
  • hair conditioning compositions suitable for leave-on use which provide hair volume-up while not deteriorating conditioning benefits such as softness, moisturized feel, and fly-away control.
  • Fig. 1 is a top view of a preferred embodiment of the Image Analysis System.
