Demand for preservatives without alcohol, paraben, isothiazolones halogens and formaldehyde, particularly within lower pH systems, is increasing. Cost-efficient progressive preservatives that represent an alternative to traditional preservative systems and follow natural ingredient trends are frequently requested. Ashland now offers Optiphen™ P technology platform to address these demands.
Optiphen DP preservative is the first preservative launched in this family. It provides comprehensive antimicrobial protection in aqueous and emulsion-type personal care formulations and incorporates an optimized delivery system to maximize the actives efficacy usually without interfering or destabilizing cosmetic formulations, such as emulsions.
Optiphen DP preservative has proven to be an effective preserving system for rinseoff-products like shampoos, shower-gels, foam-baths and more. These products generally have a slightly acidic pH, which is a necessary condition for a safe use, as explained above.
Optiphen DP preservative is well suited for high-quality care-cosmetics like creams, emulsions, lotions and gels, if they conform to the necessary pH-conditions. Optiphen DP preservative can be used in O/W-emulsions as well as in W/O Emulsions.
Ashland also recommends Optiphen DP preservative for use in wet wipe-systems. 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.
