Prebiotics
A composition which comprises a prebiotic or a mixture thereof that, upon application to an individual's skin, has a beneficial effect on the skin and that is incorporated in the composition in the form of a multiplicity of tiny beads which comprise, in addition to the prebiotic, a matrix-forming agent, for example, mannitol and hydroxypropyl methylcellulose, and a filler, for example, microcrystalline cellulose, and a personal care composition which includes the beads.

12. An aqueous composition according to claim 1 including at least about 15 wt. % water and about 0.5 to about 3 wt. % of said beads which are not soluble in the water.
13. A method for forming a multiplicity of micro beads having a diameter within the range of about 425 to about 1000 microns comprising forming a mixture of powdery ingredients comprising: (A) a prebiotic; (B) a matrix-forming agent; and (C) a filler; adding to said mixture water and forming therefrom a wet blend of the ingredients; forming the wet blend of ingredients into spherically shaped wet beads, and recovering said micro beads after drying said wet beads.
