Optiphen® Plus is the second globally approved preservative in the family of Optiphen® products developed for paraben- and formaldehyde-free preservation, particularly within lower pH systems. Optiphen® Plus is a liquid preservative formulation featuring an innovative blend of phenoxyethanol, sorbic acid and an emollient base that is ideal for slightly acidic personal care products requiring broad spectrum protection. The combination of all three ingredients offers effective protection against bacteria, yeast and mold growth while imparting emolliency. Optiphen® Plus performs best in formulations below 6.0 pH. Depending on the formulation, Optiphen® Plus has also been proven effective at pH levels above 6.0. This preservative is effective as a stand-alone system and functions well with other preservatives. Optiphen® Plus has an extensive range of applications in aqueous and emulsion-type personal care formulations and is compatible with most raw materials in the personal care industry. Ashland Chemical is the manufacturer and owner of the trademark Optiphen® Plus.
