Optiphen ND

Optiphen ND
Optiphen ND™ is the newest preservative from ISP. This complete preservative system is paraben free and does not contain formaldehyde releasers. It is effective against Gram-positive and Gram-negative bacteria, yeast, and mold. The pH of finished formulations should be 6 or below for effective utilization of this preservative. Optiphen ND is approved for use worldwide.

-Optiphen ND™ is applicable for use in a variety of personal care products including shampoos, shower gels, body washes, creams, lotions, gels, and wet wipes with an acidic pH.

-Optiphen ND™ is a liquid that can be easily added at any phase of the formulation. It can be added during pre- or post-emulsification at or below 80C.

-In aqueous systems with low amounts of emulsifiers, intensive mixing is recommended to achieve uniform dispersal of the active ingredients.

-Please note that every personal care formulation requires a preservative system that meets its specific needs. Therefore, every newly developed formulation should undergo challenge testing to ensure adequate preservation.
