Definitions

  • the present invention relates to hair conditioning compositions comprising silicone compounds.
  • the composition of the present invention provides improved shine benefit and other conditioning benefits such as softness, smoothness, and free-flowing, while reducing sticky, greasy feeling.
  • Shampooing cleans the hair by removing excess soil and sebum. However, 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.
  • 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.
  • 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 hair with a tacky, dirty feeling, thus, may cause reduced free-flowing feel on the hair. Based on the foregoing, there remains a desire to provide hair conditioning compositions suitable for leave-on use which provide improved shine benefit in addition to other conditioning benefits such as softness, smoothness, and free-flowing, while reducing sticky, greasy feeling.
  • the present invention is directed to a hair conditioning composition
