The Federal Drug management (Fda) and the town For Disease control (Cdc) recommends washing hands with soap and warm water for at least 15 seconds, scrubbing up to the wrist and under finger nails. Most of us do not wash our hands fully enough to preclude germ transmission. When washing hands with soap and water isn't an option, the Fda and Cdc recommend using a hand antiseptic, known as hand sanitizer with an alcohol content of at least 60% to be sufficient against germ transmission. Be sure to read label carefully, as many hand sanitizers with alcohol have a lower alcohol content to help preclude skin from becoming dry and damaged. Alcohol is valuable to preclude harmful germ transmission, but it is undoubtedly harsh on the skin. To combat the drying consequent of alcohol, many have added aloe and vitamin E which aid in healing and soothing the skin. Another, not so well known ingredient is called dimethione. Dimethicone, used in high end cosmetics is an emollient used to treat and preclude dry, rough skin. The key to dimethicone is that it helps not only to heal but preclude irritation of the skin. It can also be found in diaper rash ointments. Hand sanitizer can be found in spray, foam and gel forms. Gel takes a microscopic more time to dry than foam and alcohol isn't fully sufficient until it is allowed to remain on the skin for 15 seconds, so I prefer gel to foam for this reason.
