CUSHIONING WAX BEADS FOR MAKING SOLID SHAPED ARTICLES

摘要

Biologically inactive cushioning beads comprise at least one compressible cushioning component consisting essentially of a microcrystalline hydrocarbo n wax or a natural wax, the said wax being at least 30 % by weight of the biologically inactive cushioning beads. Such beads are useful for making sol id shaped articles containing biologically active ingredients by compression.
