Germaben® II is a broad spectrum, liquid preservative system. Its active components have been solubilized in propylene glycol, making them easy to incorporate into formulations. It is ready-to-use in emulsions with an oil phase of about 25% or less and water soluble formulations. Germaben II is heat sensitive and should be added to the water phase or to the emulsified portion of the formulation at a temperature of 140°F (60°C) or below, during the cool down stage, generally prior to the addition of fragrance. Adding Germaben II above 140°F (60°C) could result in compromising the preservative system in your product. Germaben II is compatible with most cosmetic ingredients and is effective over a broad pH range of 3.0 – 7.5.
Recommended use levels: 0.5 - 1%.
Appearance: Clear viscous liquid
Usage Instructions: can be used in lotion, scrub, and products made with water. Add the Germaben II when your product is 140 F or below. Higher temperatures can degrade the preservative.
Eye Safe: no
Lip Safe: no
Vegan: yes
Germaben II is an ideal preservative system for shampoos, hair conditioners and emulsion products. Germaben II minimizes the problems associated with incorporating solid Parabens. It dissolves completely in cosmetic formulations at a 1.0% concentration over a wide pH range. It can be conveniently incorporated into cold processed shampoos and into creams and lotions during their manufacture. The preferred method of addition of Germaben II is to add it slowly to the product with good stirring just prior to the addition of the fragrance. Germaben II has also been successfully used to preserve troublesome formulations containing nonionic surfactants, proteins, soluble collagen, aloe vera extracts and herbal extracts. The broad spectrum of antimicrobial activity obtained by the combination of Germall II with methylparaben and propylparaben provides the preservation protection necessary for sophisticated personal care products.
Germaben II is recommended to be used at a level of up to 1.0% . Shampoos and liquid soaps generally require less than 1.0% Germaben II. Although Germaben II provides excellent antimicrobial preservation, every developed or modified product should be challenge tested to assure preservative efficacy.
Germaben II is a clear viscous liquid with a characteristic mild odor. It is readily soluble at a level of 1.0% in both aqueous solutions and oil/water emulsions. Germaben II is a convenient, ready to-use complete antimicrobial preservative system with a broad spectrum of activity. The solubilized combination of Germaben II with methylparaben and propylparaben is effective against Gram-positive and Gram-negative bacteria and against yeast and mold. Germaben II can be used without additional co-preservatives and is compatible with essentially all cosmetic ingredients, including surfactants and proteins.
