CoSept™ PEP is a broad-spectrum preservative with ingredients approved for use in many countries. It is compatible with the vast majority of raw materials used in cosmetic and personal care products, although highly ethoxylated compounds may reduce efficacy. It is a clear, thin, colorless to light straw-colored solution of five parabens in phenoxyethanol. The phenoxyethanol imparts a slight “rose essence” aroma to the product.
As a mobile liquid, CoSept™ PEP can be easily incorporated without high temperature processing. Nonetheless, it is essentially nonvolatile and is not adversely affected by typical hot processing (up to 85°C) conditions. Due to the limited water solubility of its ingredients, addition to the oil phase (or to a water phase after addition of surfactants) will promote solution. Addition to the water phase optimizes initial antimicrobial activity, as parabens will tend to migrate into an oil phase with time. CoSept™ PEP is optimally effective at acidic to neutral pH, and is recommended for use over the pH range of 3 to 8. Typical use levels range from 0.3 to 1.0% wt.
