Germaben II-E is a clear viscous liquid preservative system with a characteristic mild odor. It is readily soluble at a level of 1.0% in both water/oil and oil/water emulsions, but not in water alone.
Germaben II-E is a solubilized combination of Germall II with methylparaben and propylparaben in propylene glycol. It is a complete broad spectrum antimicrobial preservative system that is effective against Gram-positive and Gram-negative bacteria and against yeast and mold.
Germaben II-E was developed for creams and lotions that present special preservation problems involving partial inactivation of parabens by ingredients in the formulation. Germaben II-E can be used in problem formulations, without the need for additional co-preservatives. It is compatible with almost all cosmetic ingredients, including surfactants and proteins.
All the components of Germaben II-E are permanently listed by the EU. Germaben II-E is a complete preservative system, in clear liquid form, that was developed especially for cosmetic creams and lotions that present preservation problems caused by the presence of paraben inactivating materials.
Germaben II-E includes a total concentration of 20% parabens predissolved in propylene glycol for easy and convenient addition to cosmetic formulations. It minimizes the difficulties associated with incorporating solid parabens.
Germaben II-E can be conveniently incorporated into hot or cold processed shampoos, creams and lotions during their manufacture. The preferred method of addition is to add it slowly to the cosmetic formulation with good stirring after emulsification and just prior to the addition of fragrance. In fact, some fragrance materials are most effectively incorporated into cosmetics by predissolving them in Germaben II-E and then adding the mixture slowly to the finished formulation.
Germaben II-E is recommended to be used at a level of 1.0%. This level provides to the product: 0.20% Germall II, 0.10% methylparaben, 0.10% propylparaben and 0.60% propylene glycol. Although Germaben II-E provides excellent antimicrobial preservation, every developed or modified product should be challenge tested to assure preservative efficacy.
