by other means are minimized and easily biodegraded alcohols with a larger number of oh functional groups constitute a group of organic molecules that are distinguished in dermatology and cosmetics because of their excellent skin softening and moisturizing properties among these the most outstanding are glycerin and the glycols especially the propylene glycols glycerin is a tri alcohol propanetriol soluble in water and widely used in pharmaceutical preparations as a solvent and humectant on their part the organic acids are distinctive as they are also used in dermatology and cosmetics because of their skin exfoliating properties due to their capacity to remove the first layer of old epithelial cells within this group of chemical products the most outstanding is glycolic acid it corresponds to hydroxyacetic acid with the formula hoch 2 cooh and has the property of irritating the skin very gently and is used a great deal in human cosmetology as an exfoliating agent other suitable exfoliating compounds include but are not limited to lactic acid citric acid salicylic acid and tannic acid the total amount of disinfectant s and or biocide s used in the present invention is less than or equal to about 425 ml per about 1000 ml u00b1 about 500 ml of distilled water c s p in one embodiment the total amount of disinfectant s and or biocide s is about 200 ml u00b1 about 100 ml in another embodiment the total amount of disinfectant s and or biocide s is about 208 u00b1 about 104 ml in another embodiment the total amount of disinfectant s and or biocide.
