General description

Preservative blend consisting of Methyl p-hydroxybenzoate, Ethyl p-hydroxybenzoate, and Phenoxyethanol.

Phenonip® ME is a broad spectrum antimicrobial agent comprising a synergistic blend of esters of para-hydroxybenzoic acid (parabens) in phenoxyethanol designed for preservation of a wide range of cosmetics and toiletries.


Phenonip® ME provides activity against gram positive and gram negative bacteria, yeasts and molds.
It retains activity in the presence of most cosmetic ingredients.
Phenonip® ME protects most types of personal care products from microbial contamination. As with other preservatives, the correct use concentration depends upon several factors, including the chemical and physical nature of the product, its ability to support microbial growth and the likelihood of recontamination during use. Experience has shown that Phenonip® ME will preserve cosmetics and toiletries when incorporated at concentrations from 0.25 % to 1.2 %. 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® ME at concentrations between 0.25 % to 0.8 %. Products with high protein content may require levels from 0.6 % - 1 %. Other surfactant- based products, for example liquid dishwashing detergents, are generally preserved with Phenonip® ME over the range 0.2 %- 0.6 %. Emuslified systems, both O/W and W/O types, may be effectively preserved by the addition of Phenonip® ME at 0.6 %- 1 %. Phenonip® ME can also be used to preserve emulsions based on nonionic surfactants, but slightly increased concentrations may be required, e.g. 0.8 -1.2 %.
