Optiphen BD is a globally approved, 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 BD was designed specifically for personal care formulations with a pH up to 6.4. It is based on a combination of nature-identical substances: Benzyl Alcohol, Dehydroacetic Acid and Benzoic acid and is included in our family of modern preservative products.
ECOCERT-, COSMOS-, NATRUE- and BDIH-compliant, Optiphen BD preservative is a synthetic version of naturally occurring substances with excellent efficacy and global approval for rinse-off and leave-on applications. It can be selected for natural or organic personal care products in order to meet the above standards.
Optiphen BD 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.
Optiphen BD preservative is well suited for high-quality care-cosmetics like creams, emulsions, lotions and gels, if they conform to the necessary pHconditions. Optiphen BD preservative can be used in O/W-emulsions as well as in W/O-emulsions.
We can also recommend Optiphen BD 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 produces. This helps to eliminate any possible influence of the base sheet.
