Safe. Therefore, o-cymene 5-alcohol is a low-irritation, high-efficiency bactericide. Low doses will not harm the skin, so o-cymene-5-alcohol hand sanitizer is safe. The liposomes of the patented technology of the present invention encapsulate the bactericidal ingredients. Hand sanitizer uses liposomes to encapsulate O-cymene 5-ol to form a sterilizing coating, which increases the water solubility of O-cymene 5-ol, improves the stability of the product, and extends the shelf life of the product.
