  • Patent number: 8535653
    Abstract: An article for sequential dispensing of vapors, notably evaporable fragrances, comprises separated first and second liquids (22, 24). Liquid (22) issues first. Its evaporation may be assisted by a wick (26). The simultaneous evaporation of the second liquid is prevented by an intermediate liquid phase (20). As liquid (22) issues the liquid levels change and there comes a point at which the intermediate phase can no longer prevent the second liquid (24) from flowing past it, to the region from which it can be evaporated. Solids, especially gels, may be employed instead of liquids (22, 24).

  • Publication number: 20080276523
    Abstract: A device for releasing to the air an active ingredient in vapour phase comprises a reservoir (1) which holds a liquid composition (8) in liquid contact with a volatilisation surface (2), the composition comprising: i) an organic solution phase comprising an ionisable surfactant, ii) an aqueous phase comprising colloidal particles with a surface charge opposite to that of the head group of the surfactant when ionised, and iii) an active ingredient. The composition spontaneously forms a thin film on the volatilisation driven by self-assembly of the colloidal particles and immobilised surfactant at the interface between the two phases.
