Abstract
The present invention is concerned with a method of forming a substantially non odorous barrier film, on human or animal skin on which a fragrance is to be applied, said method comprises applying a dermatologically inactive film-forming polymer to human or animal skin in a cosmetically acceptable carrier to form a substantially non odorous barrier film, on human or animal skin, onto which a fragrance is to be applied. A composition for use with the method of the invention is also disclosed.
Claims9
The use of a barrier composition comprising a dermatologically inactive film-forming polymer in a cosmetically acceptable carrier therefore to form a substantially non odorous barrier film, on human or animal skin, onto which a fragrance is to be applied.
The use of a barrier composition as claimed in any of the preceding claims in which the cosmetically acceptable carrier is:
- an alcohol where the polymer is a vinyl ether copolymer;
- ethylacetate where the polymer is a methacrylate polymer;
- an alcohol or ketone where the polymer is a polyacrylate polymer;
- acetone or ethylacetate where the polymer is a polyester;
- acetone where the polymer is a polyluorocarbon, and an alcohol where the polymer is a quaternary hydroxypropyl chitosan.
The use of a composition as claimed in any of the preceding claims which further comprises one or more of the group consisting a surfactant, plasticiser and a pH controlling agent.
A fragrance applicator kit comprising a fragrance and a barrier composition comprising a dermatologically inactive film-forming polymer and a cosmetically acceptable carrier therefore.
A method of improving the likelihood of a given fragrance lasting a given time and emitting a given smell, the method comprising the steps of:
- applying a barrier composition comprising a dermatologically inactive film-forming polymer in a cosmetically acceptable carrier therefore to human or animal skin to form a substantially non-odorous fragrance resistive barrier film thereon, and
- applying a fragrance onto said substantially non-odorous fragrance resistive barrier film.
