Definitions

  • the present invention relates to cosmetic compositions and in particular to long- lasting fragrance compositions.
  • compositions that they comprise a fragrance.
  • a fragrance can mask unpleasant odours or can improve consumer acceptance of a composition through delivering a pleasant smell.
  • the sole purpose of some compositions is the application of a pleasant odour to the skin, hair or other suitable substrate.
  • the fragrant effect of these compositions is transitory and the fragrance quickly becomes imperceptible.
  • the fragrance may be formulated in such a way as to include a higher proportion of fragrance materials with a low volatility. This means the fragrance persists for longer. However, using less volatile materials restricts the fragrance characters that can be achieved. It has also been suggested that it may be possible to utilise cyclic oligosaccharides, and in particular cyclodextrins.
  • JP-A-50/63126 discloses perfume and cyclodextrin complexes for use in bath preparations
  • JP-A-7/241333 discloses a long-lasting, room deodorising composition containing a fragrance and cyclodextrin.
  • compositions comprising fragrance and greater than 1.2%, by weight, cyclic oligosaccharide having an average degree of substitution of at least about 1.6 provide an initial burst of fragrance and improved fragrance longevity.
  • the stability profile of the complexes formed between the fragrance and the cyclic oligosaccharides of the present invention is such that a perceptible amount of fragrance is released over a sufficiently long time to satisfy the consumers desire for long lasting fragrance.
  • cosmetic compositions comprising: (a) fragrance; and
  • compositions of the present invention provide a long-lasting fragrance while at the same time having a 'burst' of fragrance on application.
  • the present invention relates to compositions comprising two essential elements, fragrance and greater than 1.2%, by weight, cyclic oligosaccharide having an average degree of substitution of at least about 1.6. These two elements will be described in more detail below.
  • fragrance material As used herein the term "fragrance" is used to indicate any odouriferous material. Any fragrance material suitable for use in cosmetic compositions may be used herein but the fragrance will most often be liquid at ambient temperatures. Preferably, the fragrance material will be present at a level of from about 0.01 % to about 40%, more preferably from about 0.5% to about 30%, even more preferably from about 2.5% to about 25%, even more preferably still from about 8% to about 15%, by weight, of total composition.

  • the fragrance material may be released from the pro- fragrances in a number of ways. For example, the fragrance may be released as a result of simple hydrolysis, or by a shift in an equilibrium reaction, or by a pH- change, or by enzymatic release.
  • the fragrances herein can be relatively simple in their compositions, comprising a single chemical, or can comprise highly sophisticated complex mixtures of natural and synthetic chemical components, all chosen to provide any desired odour.
  • the fragrance materials of the present invention will have boiling points (BP) of about 500°C or lower, more preferably about 400°C or lower, even more preferably about 350°C or lower.
