The U.S. Army seeks development, testing, and production of prototype phage hygiene sprays for intimate skin applications.
- **Government buyer:** U.S. Army Contracting Command–Aberdeen Proving Ground, Orlando office; end-user: DEVCOM Soldier Center (SC).
- **Named companies:** **Intralytix** supplies the PhageShield phage cocktail; Desert in Bloom Cosmetic Labs LLC is identified to develop, test, and produce the prototypes.
- **Products requested:** 100 prototype spray bottles total, with no part numbers specified:
  - 50 bottles containing optimized formulation and PhageShield, at a concentration greater than 1E8 PFU/ml.
  - 50 bottles containing the optimized formulation without phage.
  - Both types: opaque 15 ml HDPE bottles filled to 14 ml, pH 7–7.5 buffer, fine-mist pumps delivering 70–150 μl, and 360-degree spray operation, including upside down.
- **Services requested:** Develop and optimize three formulation iterations using Government-furnished PhageShield; provide ingredient and concentration data; conduct freeze/thaw, accelerated heat-stability, preservative-challenge, ingredient-toxicity, and Human Repeated Insult Patch Test (HRIPT) testing.
- **Notable requirements:** Formulations target UTI-causing E. coli and must maintain phage stability, including at 45°C. Bottles require sealed caps and necks, separate numbered packaging, and overnight shipment on ice or ice packs at 2–8°C. Phage titer and thermal-stability testing by Soldier Center is outside the contractor's stated testing scope.
- **Schedule:** Performance period is 10 months after award, with delivery planned within up to 40 weeks after award.
