Optiphen ND is a mild globally-approved preservative consisting of a liquid blend of phenoxyethanol, benzoic acid, and dehydroacetic acid.

Benzoic acid, a crystalline solid that melts at 122ºC and boils at 249ºC, is a simple aromatic carboxylic acid widely distributed in nature in the free state or in the form of salts. Appreciable amounts are found in gum benzoin and in berries, such as cranberries. The free acid is found in natural products such as prunes, ripe cloves and oil of anise seeds. In addition to being used for cosmetic preservation, it is also employed as a preservative in foods, juices, fats, and oil, for pharmaceutical and medicinal uses, and as an ingredient in antiseptic ointments for the treatment of fungal infections of the skin.

Dehydroacetic acid, a cyclic ketone acid, has antifungal and antibacterial properties. Due to the presence of these organic acids in the system, Optiphen ND offers broad spectrum protection against bacteria, yeast, and mold and is most effective in applications such as creams and lotions where the pH is not higher than 6.0. It is also very effectively used in the preservation of wipes, which is a growing market segment.
