Optiphen ND is a broad spectrum liquid preservative system that does not contain any halo-organic compounds, formaldehyde, formaldehyde releasers or parabens. It is effective against Gram-negative bacteria, yeast and mold. Optiphen ND, a globally approved system, was designed specifically for personal care formulations with a pH up to 6.4 due to the inclusion of organic acids. It is based on a combination of nature-identical organic acids: Benzoic acid and Dehydroacetic acid in Phenoxyethanol and can be classified as a “progressive preservative”.

Suggested Applications



Optiphen ND preservative has proven to be an effective preserving system for rinse-off-products like shampoos, shower-gels, foam-baths etc., as these products generally have slightly acidic pH, which is a necessary condition for a safe use, as explained above.

Due to its good skin-compatibility Optiphen ND preservative is well suited for high-quality care-cosmetics like creams, emulsions, lotions and gels, if they conform to the necessary pH-conditions. On account of its excellent dispensability Optiphen ND preservative can be used in O/W-emulsions as well as in W/O-emulsions.

Wet wipes

We can also recommend Optiphen ND preservative for use in wet wipes systems due to its good antifungal effect. It is important to control the acidic pH-value after the wipe is produced. This helps to eliminate any possible influence of the base sheet.
