Abstract
Abstract There is disclosed a deodorant composition which has its volatile components such as perfume and deodorant components each adsorbed onto an inert solid carrier. Preferably a plurality of volatile components of different relative volatilities are each adsorbed onto an inert solid carrier to provide a plurality of component-bearing, solid fractions which are blended together in preselected portions to provide the desired proportional release rate of each of the volatile components. The blended solid fractions are packaged into a volatile releasing container. The composition does not exhibit the shrinkage characteristic of other compositions such as solid deodorants and can be provided with a controlled and constant relative release rate of its volatile component throughout its useful life.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
79 words
A method of providing a plurality of volatile-dispensing products of the same volatile-dispensing composition and bulk volume but with varied volatility which comprises adsorbing the volatile-dispensing composition onto a plurality of varied size range fractions of an inert solid adsorbent carrier of spherical or substantially spherical particles and packaging each of the resultant adsorbate-solid fractions of varied particle size range into containers having a cross-sectional diagonal at least about 5 times the average particle diameter of said adsorbent particles.
Claim 2
Independent Claim
79 words
A method of providing a plurality of volatile-dispensing products of the same volatile-dispensing composition and bulk volume but with varied volatility which comprises adsorbing the volatile-dispensing composition onto a plurality of varied size range fractions of an inert solid adsorbent carrier of spherical or substantially spherical particles and packaging each of the resultant adsorbate-solid fractions of varied particle size range into containers having a cross-sectional diagonal at least about 5 times the average particle diameter of said adsorbent particles.
Claim 3
Dependent Claim
11 words
The method of claim 1 wherein said solid adsorbent is silica.
Claim 4
Dependent Claim
13 words
The method of claim 1 wherein said solid adsorbent is expanded calcium silicate.
Claim 5
Dependent Claim
115 words
A product to release a deodorant vapor mixture of a plurality of volatile deodorant ingredients comprising a package of a mixture of a plurality of volatile-deodorant-bearing fractions, each fraction comprising an adsorbate of one of said volatile deodorant components adsorbed onto inert solid carrier particles having particle diameters from 0.005 to 1 inch, and each fraction having a preselected, proportional release rate of its respective volatile component by preselection of one or more of solid particle specific surface area, adsorbate concentration, particle size and adsorption isotherm characteristics and being present at a concentration to provide a mixture of deodorant vapor released from said product that is of a preselected, desired composition throughout its useful life.
Claim 6
Dependent Claim
115 words
A product to release a deodorant vapor mixture of a plurality of volatile deodorant ingredients comprising a package of a mixture of a plurality of volatile-deodorant-bearing fractions, each fraction comprising an adsorbate of one of said volatile deodorant components adsorbed onto inert solid carrier particles having particle diameters from 0.005 to 1 inch, and each fraction having a preselected, proportional release rate of its respective volatile component by preselection of one or more of solid particle specific surface area, adsorbate concentration, particle size and adsorption isotherm characteristics and being present at a concentration to provide a mixture of deodorant vapor released from said product that is of a preselected, desired composition throughout its useful life.
Claim 7
Dependent Claim
30 words
The product of claim 4 wherein said solid fractions have preselected absorption isotherm characteristics to release a vapor mixture of substantial constant composition throughout the useful life of said product.
Claim 8
Dependent Claim
11 words
The product of claim 4 wherein said solid carrier is charcoal.
Claim 9
Dependent Claim
11 words
The product of claim 4 wherein said solid carrier is silica.
Claim 10
Dependent Claim
