Definitions

  • This invention relates to deodorant compositions suitable for application to the human skin, in particular liquid, solid and aerosol compositions.
  • Such compositions may be suitable for use when delivered from a roll-on dispenser, or from a pump action dispenser, or as a stick form, but most preferably from a propellant driven aerosol.
  • deodorant and antiperspirant market is dominated with products which are based on aluminium or zirconium salts, which are intended to prevent, or at least to control perspiration at the skin surface, particularly at the underarm, whilst at the same time providing a perceived degree of deodorancy.
  • deodorant agents Whilst there are many known deodorant agents available to the skilled man to prepare deodorant compositions, there is still a demand for new deodorant compositions which contain conventional known deodorant agents (which may for example be organic, or based on metal salts) which have improved sensory or skin benefit properties. Such deodorant agents may not only have good efficacy in eliminating odour, but may also provide to the users skin such benefits such as moisturizing and skin elasticity benefits, thereby improving the usage properties of the composition.
