Phenonip Preservative
Phenonip Preservative

Phenonip was designed with cosmetics in mind and is especially effective in preventing bacteria, mold and fungal growth. It is especially effective in oil-based products, but also works well in aqueous solutions. Broad spectrum, liquid preservative ideal in variety of personal care applications, including oil-in-water, water-in-oil & all oil formulations such as lotions, creams, shampoos, conditioners, liquid soaps, scrubs and balms. It can be used in emulsions and anhydrous formulations. Effective in pH range of 3.0 - 8.0.
Phenonip withstands high temperatures up to 176 F and is preferred over Germaben II for high temp applications.
Phenonip can be added to the aqueous phase readily. It is 100% oil-soluble & .5% soluble in water. In emulsified systems, Phenonip is readily dissolved in the liquid phase prior to emulsification, although it is often good practice to divide the Phenonip content between the water & oil phases during their preparation (ie for lotion, add .5% to water phase & .5% to oil phase).
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 140-176F prior to Phenonip addition will, in most instances, allow the appropriate quantity to be dissolved.
For aqueous systems which cannot be heated, Phenonip can be incorporated by preparing a concentrate in a suitable solvent, e.g. propylene glycol or glycerin, and stirring this concentrate into the water.
Emulsified systems, both o/w and w/o types, may be effectively preserved by the addition of Phenonip.
Although Phenonip provides excellent antimicrobial preservation, individual testing should be done to assure preservative efficacy.
