Latest Patents

Schuster’s listed patents describe methods for producing and stabilizing compounds used in per-salt chemistry.

- **Process for the Production of a Stable Per Salt.** This process produces a stable per salt containing both sodium percarbonate and sodium perborate. A solution supersaturated with both compounds is introduced to nuclei consisting of sodium percarbonate, sodium perborate, or both.

- **Process for the Production of Stabilized Sodium Percarbonate.** This method forms sodium percarbonate particles with a sodium percarbonate nucleus encased in a layer of dehydrated sodium perborate and sodium silicate. The particles are prepared by spraying the sodium percarbonate with supersaturated sodium perborate and sodium silicate solutions, then drying them to remove at least some of the added water.

Career Highlights

Schuster’s work is associated with Deutsche Gold- und Silber-Scheideanstalt vormals Roessler and Degussa Aktiengesellschaft. The patents attributed to him focus on particle formation, coating, and stabilization in sodium percarbonate and sodium perborate production.
