Desert Essence Tea Tree Oil Probiotic Hand Sanitizer is specially formulated to provide good bacteria and kill 99.9% of harmful germs with the fresh scent of inherently cleansing Australian Tea Tree Oil. It uses a patented technology to create a “membrane” around the probiotic to protect it from the antibacterial formula. Probiotic benefits will be delivered after the sanitizer activity finishes . This means the sanitizer doesn’t kill the probiotic, and the probiotic doesn’t neutralize the sanitizer. The bad bacteria is eliminated, and the probiotic thrives. A powerful combination of botanical extracts including Tea Tree Oil, Thyme, Elderberry and Echinacea also help reduce bacteria.
