Mixing a controlled amount of agar with regular oral, dental or skin hygiene compositions allows manufacture of homogenous, semi-solid single-use lumps or beads (200). Agar or analogous structural gelling agents confer sufficient rigidity and a sufficiently high melting point for storage, yet allow disruption of the bead on the skin or in the mouth without residue. Dental or skin care packs (124) carry cast in-situ beads each selected from a variety of active compositions. Shape, colour and flavour variations (124C) motivate children towards better dental care.
