Title (EN) PERFUME FIXATIVES COMPRISING POLYVINYLPYRROLIDONE AND HYDROXYPROPYL CELLULOSE
(FR) FIXATEURS DE PARFUMS COMPRENANT DE LA POLYVINYLPYRROLIDONE ET DE L'HYDROXYPROPYLE CELLULOSE
Abstract:
(EN) A perfume fixative comprises: (a) polyvinylpyrrolidone (PVP); (b) hydroxypropyl cellulose (HPC); and (c) hydrophobic oil. The perfume fixative is used by being incorporated in a perfume-containing formulation or product. The fixative is found to be effective in enhancing perfume life, even when the fixative is used at low levels. The efficacy even at low levels is surprising and unexpected, and the reason for this efficacy is not yet known. For practical reasons, the PVP and HPC together should not constitute more than about 0.5% by weight of the perfume-containing product. If these materials are present at higher levels they are discernible by the user, either by sight or feel, which is undesirable. However, the fixative is found to be effective in an amount corresponding to this constraint and also at lower levels. The invention also covers mixtures of perfume and fixative, mixtures of product base and fixative, and perfumed products including perfume and fixative.
(FR) La présente invention se rapporte à un fixateur de parfum comprenant: (a) de la polyvinylpyrrolidone (PVP), (b) de l'hydroxypropyle cellulose et (c) de l'huile hydrophobe. On utilise le fixateur de parfum en l'incorporant dans une formulation ou un produit renfermant du parfum. On a constaté que le fixateur est efficace pour l'amélioration de la tenue du parfum, même lorsqu'il n'est utilisé qu'à faibles quantités. Cette efficacité est d'autant plus surprenante et inattendue que le fixateur est utilisé à faibles quantités, et la raison en demeure inconnue. Pour des raisons pratiques, les PVP et HPC ne doivent pas constituer conjointement plus de 0,5 % en poids du produit renfermant le parfum. Si ces matières sont présentes à des quantités plus importantes, l'utilisateur les verra ou les sentira, ce qui n'est pas souhaitable. En revanche, on a constaté que le fixateur est efficace en quantité proportionnelle à cette contrainte ainsi qu'à des quantités inférieures. Cette invention couvre également des mélanges de parfums et de fixateurs, des mélanges de bases et de fixateurs de produit, des produits parfumés renfermant un parfum ainsi que des fixateurs.
