A controlled release substance containing organosilica sol-gels is provided. The organosilica sol-gels may be further functionalized with amino groups to control the rate of release of encapsulated molecules. The controlled release substance may be utilized as a controlled release fabric care substance, including at least one active fabric care substance in a host matrix comprising an organosilica gel. The fabric care substance may be at least one of a protein, enzyme, fragrance, anti-static agent, fabric softener, dye, or detergent, and may be in bead form, particle form or powder form.
