Description A true, multi-functional ingredient, caprylyl glycol also acts as a humectant and wetting agent in cosmetic and skin care formulations in addition to providing viscosity modification in some formulations. This makes Optiphen more than just a preservative. Optiphen not only provides broad spectrum preservation against bacteria, yeast, and mold, the presence of caprylyl glycol imparts an exceptional feel to the finished formulation making it useful in creams, sunscreens, lotions, color cosmetics, body washes and shampoo applications. Optiphen is easy to use since it is in liquid form, and can be directly added to a formulation during pre or post-emulsification phase below 40C. If you add Optiphen to your product at above 40C, it is highly likely that the heat will destroy much of the preserving qualities of the Optiphen. Therefore, we suggest adding Optiphen to your formulation at around 40C just to be safe. However, if optiphen is added to an emulsion at too low of a temperature, the emulsion may become unstable, and you will see the oil and water phase begin to separate. Optiphen is compatible with most raw ingredients used in the cosmetic industry. Usage rate is .75%- 1.5% of your formulation. Appearance: Clear liquid Effective pH range: pH 4.0 – 8.0 Mix Method: Add at last step. Avoid temperature above 40C. Heat Resistance: Avoid heat above 40C
