Germaben
II-E is a clear, viscous, liquid preservative system designed for
emulsion systems with oil phases greater than 25%. 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 is a complete broad
spectrum antimicrobial preservative system that is effective against
Gram-positive and Gram-negative bacteria, yeast, and mold.
Germaben II is approved for use in the Americas and all the components of Germaben II-E are permanently listed by the EU. |
|
| Applications |
 |
Recommended use level range is 0.5-1.0%. |
|
Can be used in a wide pH-range (3.0-7.5). |
|
Compatible with most cosmetic ingredients. |
|
Readily soluble at a level of 1.0% in most water/oil and oil/water emulsions but not in water alone. |
|
Can be conveniently incorporated into hot or cold processed creams and lotions during their manufacture. |
|
Preferred
method of addition is to add it slowly to the cosmetic formulation
below 60°C 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 pre-dissolving them in
Germaben II-E and then adding the mixture slowly to the finished
formulation. |
|
Recent
data shows Germaben II can be added at emulsification temperatures, but
it is always best to add the preservative at the coolest temperature
possible. |
|
|
| Every
cosmetic formulation requires a specific preservative system to meet
its individual needs. Therefore, every newly developed or modified
product should be challenge tested to assure
preservative efficacy. |
