Abstract
Compositions comprise carbon particles combined with white odor-controlling agents by means of binders. The preferred particle form of the compositions is substantially lighter in color than the original carbon, and the resulting particles are preferred for use in the manufacture of catamenials, diapers, bandages, and the like. Particles comprising carbon coated with zeolites are not only desirably lighter in color, but also control a broad spectrum of malodors associated with body fluids.
Claims9
A sanitary napkin or pantiliner containing at least about 0.1 grams of odor-controlling bonded particles comprising cohesive mixture of:
- (a) carbon particles having a black original color,
- said carbon particles being substantially coated with:
- (1) white particles selected from the group consisting of white odor-controlling agents and white color masking material;
- and
- (2) a water-soluble or water-dispersible binder material;
- (b) said bonded particles being lighter in color compared with said original color of said carbon particles;
- and
- (c) wherein said carbon particles have a weight ratio to said white particles in the range of from about 20:1 to about 1:5.
