Definitions

  • the present invention relates to hair conditioning compositions containing an antidandruff agent.
  • the present invention relates to hair conditioning compositions which provide antidandruff benefits and refreshing feeling as well as conditioning benefits.
  • 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.
  • Such consumers who prefer the conventional conditioner formulations value the relatively higher conditioning effect, or convenience of changing the amount of conditioning depending on the condition of hair or amount of hair.
  • Antidandruff hair conditioning compositions are advantageous in that the composition is applied to the hair after the shampoo stage, thus, effective deposition on the scalp can be expected. Especially, leave-on hair conditioning compositions are more advantageous in that antidandruff agents remain on the hair as there is no rinsing step, thus, more effective deposition on the scalp can be expected. Additionally, the leave-on compositions are more convenient because the consumer can use the product at any time and does not have to wait to rinse the product.
  • conditioning agents such as cationic surfactants, cationic polymers, silicone conditioning agents, hydrocarbon and other organic oils and solid aliphatics such as fatty alcohols, and mixtures thereof.
  • Most of these conditioning agents are known to provide various conditioning benefits such as moisturized feel, softness, and static control to the hair, however, are also known to provide stickiness or greasy or waxy feeling to the hair.
  • hair conditioning compositions comprising the conditioning agent described above, can provide conditioning benefits, however, also provide stickiness or greasy or waxy feeling to the hair.
  • leave-on hair conditioning compositions provide more stickiness or greasy or waxy feeling as there is no rinsing step.
  • the stickiness or greasy or waxy feeling is not desirable for substantial proportion of consumers, especially for consumers who desire hair conditioning compositions to provide antidandruff benefit as such consumers tend to desire that compositions to also provide refreshing feeling.
  • conditioning compositions, especially leave-on compositions are often difficult to spread and can deposit too much conditioning agent in an uneven manner. This causes the hair to develop a dirty, coated feel and leaves the hair limp and without body. This is particularly noticeable when the compositions are used repeatedly and when the hair is not washed daily.
  • polysiloxane resins could be used as hair conditioning agents.
  • GB-A-2,297,757 incorporated by reference herein, describes low viscosity organofunctionalized siloxysilicates and gives examples of their use in a hair care compositions.
