Optiphen ND

Optiphen ND (Phenoxyethanol (and) Benzoic Acid (and) Dehydroacetic Acid) is the latest innovation in preservative technology from ISP, offering a complete, paraben-free preservative system that is free from formaldehyde releasers. This remarkable ingredient is effective against a wide range of microbial threats, including both Gram-positive and Gram-negative bacteria, yeast, and mold, making it an essential component for ensuring the safety and longevity of personal care products. With a recommended pH of 6 or below for optimal performance, Optiphen ND is versatile enough for use in various formulations, including shampoos, shower gels, body washes, creams, lotions, gels, and even wet wipes, particularly those with an acidic pH. Its liquid form allows for easy incorporation into formulations, whether added pre- or post-emulsification at temperatures at or below 80°C. Moreover, for aqueous systems with minimal emulsifiers, intensive mixing is encouraged to achieve a uniform distribution of its active ingredients. To guarantee the effectiveness of this preservative in any new formulation, it is crucial to conduct challenge testing tailored to meet specific preservation needs.
