Phenonip®XB drops problematic butylparaben and isobutylparaben from the preservative mix and is approved for use in USA and EU. CAS#: Mixture Broad spectrum, liquid preservative system ideal for use in a wide variety of personal care applications. Effective against Gram-positive and Gram-negative bacteria, yeasts and molds and retains activity in the presence of most cosmetic ingredients. Phenonip®XB is oil soluble. It can be used in emulsions and anhydrous formulations. • Non-volatile - there is no loss of preservative due to volatility even on prolonged storage. • Highly stable - aqueous solutions of Phenonip®XB can withstand autoclave sterilisation with no loss of activity. • Phenonip®XB has an excellent toxicological profile and is non-irritant to skin, eye and mucous membranes at normal use concentrations. • The components of Phenonip® are biodegradable at the low concentrations found in effluent.

The higher concentrations are generally required only for formulations which, by nature, are particularly difficult to preserve.  Shampoos and foam baths may be preserved with Phenonip® XB at concentrations between 0.25 % to 0.65 %. Products with high protein content may require levels from 0.5 % - 1 %. Other surfactant- based products, for example liquid dishwashing detergents, are generally preserved with Phenonip® XB over the range 0.2 %- 0.6 %. Emulsified systems, both O/W and W/O types, may be effectively preserved by the addition of Phenonip® XB at 0.6 %- 0.8 %. Phenonip® XB can also be used to preserve emulsions based on nonionic surfactants, but slightly increased concentrations may be required, e.g. 0.8 -1 %. Phenonip® XB can be added to the aqueous phase readily up to its limit of solubility. The relatively low aqueous solubility of Phenonip® XB means that if the water content of the formulation is low, it may not be convenient to add the preservative directly to water during manufacture. Heating the water to 60 – 70°C prior to Phenonip® XB addition will, in most instances, allow the appropriate quantity to be dissolved. For aqueous systems which cannot be heated, Phenonip® XB can be incorporated by preparing a concentrate in a suitable solvent, e.g. Propylene Glycol, and stirring this concentrate into the water to give a final Phenonip® XB concentration below its maximum water solubility.  In emulsified systems, Phenonip® XB is readily dissolved in the lipid phase prior to emulsification although it is often good practice to divide the Phenonip® XB content between the aqueous and the lipid phases during their preparation. To add Phenonip® XB into the final emulsion during the cooling stage is also possible for a lot of emulsions.  In surfactant and detergent based products Phenonip® XB can be dissolved in the surfactant prior to the addition of water and other ingredients. • Retains activity over the range pH 3.0 - 8.0.
