Patent number: 5626852Abstract: Described is a fragrancing composition having fragrancing components that are not activated until, e.g., application to the skin of a human. The composition is alkaline or (if anhydrous) capable of producing an alkaline pH when in contact with water, prior to application, and includes (1) a vehicle such that when the composition is in contact with water, prior to application, the composition is at an alkaline pH; and (2) at least one potential fragrance that is at least one compound having little or no odor in the alkaline composition but which, e.g., is hydrolyzed in a lower pH environment to produce compounds having a relatively strong aroma. Upon application of the alkaline composition to the skin surface, the strong buffering capacity of the skin (the surface of which has a normal pH of 5.5-7.0) neutralizes alkalinity of the composition (lowers pH) so as to restore normal skin surface pH; the potential fragrance is then hydrolyzed at the lower pH to release the compound having relatively strong aroma.Type: GrantFiled: December 23, 1994Date of Patent: May 6, 1997Assignees: The Mennen Company, Takasago International CorporationInventors: Robert Suffis, Morton L.

Patent number: 4614299Abstract: Described is an article which dispenses at a constant rate a volatile composition of matter into the atmosphere surrounding the article which volatile composition of matter can be, for example, a perfume composition or air freshener, which article is a container which is a hollow totally enclosed flexible, rigid or partially flexible-partially rigid structure comprising a thin shell totally enclosing an inner void, with the thin shell having a part thereof as a microporous polymer which contains a plurality of finite filler particles which that when the article is located in the ambient environment, the volatile material molecules are passed through the microporous polymer by means of an adsorption desorption mechanism or by means of capillary action. The volatile substance which is a composition of matter is enabled to pass through the microporous polymer at a constant mass flow rate of both the individual volatile components and the total composition.Type: GrantFiled: June 13, 1984Date of Patent: September 30, 1986Assignee: International Flavors & Fragrances Inc.Inventors: Augustinus G.

Patent number: 4605165Abstract: Described is an article useful for dispensing at a constant rate, continuously or discontinuously for discrete periods of time a volatile composition of matter such as an air freshener or perfume composition into the atmosphere surrounding said article, the article being a hollow totally enclosed flexible, rigid or partially flexible-partially rigid structure comprising a thin shell totally enclosing an inner void with part of the thin shell comprising a microporous polymer containing a plurality of finite solid filler particles whereby when the article is located in the ambient environment, the volatile material molecules are transported through the porous polymer at a substantially constant mass flow rate both of the individual volatile components and totally through the porous polymer. The functioning of the article is enabled because the microporous polymer section has (i) the property of transporting water vapor at a rate of between 50 up to 1000 g/m.sup.2 /day at about 25.degree.
