Abstract
A method for molding an agglomeration of fused microspheres to create a fragrance delivery system by use of room temperature setting binders. The molded pre-glass agglomeration has an extended fragrance release time exceeding a year and a half, and uses microcapillary action to quickly uptake oils and alcohols. The molded pre-glass agglomeration provides a slow release of fragrance without the escape of any residual liquid. The molded pre-glass agglomeration may be replenished, an unlimited number of times, with fragrance containing oils and alcohols after the odor fades. The molded pre-glass agglomerations may also be colored or dyed.
Claims24
A process for making a shaped fragrance delivery system comprising:
- a. preparing a mixture of adsorptive material comprised of naturally fused microspheres and free-flowing powder, comprising:
- SiO2 about 60 to about 75%;
- Na2O about 10 to about 35%;
- K2O about 2 to about 20%;
- B2O3 about 5 to about 20%;
- and
- CaO about 0.5 to about 12%;
- b. isolating a portion of said mixture in which all of said naturally fused microspheres and said free-flowing powder are sufficiently small to allow said portion to combine with a binder and water to form a slurry;
- c. combining said portion with a binder and water to form a slurry;
- d. mixing said slurry;
- e. forming said mixed slurry into a desired shape to create a shaped fragrance delivery system;
- and
- f. drying said shaped fragrance delivery system.
