Desert Essence Tea Tree Oil & Lemongrass Probiotic Hand Sanitizer is specially formulated to provide good bacteria and kill 99.9% of harmful germs with the invigorating scent of Lemongrass Essential 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.
