The Chemistry Store Germaben II, 8 oz.

Description

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 activity obtained by the combination of germall ii with methyl paraben and propyl paraben 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%. This level provides to the product: 0.30% germall II, 0.11% methyl paraben, 0.03% propyl paraben and 0.56% propylene glycol. Shampoos and liquid soaps generally require less than 1.0% germaben II. Although germaben II provides excellent 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 preservative system with a broad spectrum of activity. The solubilized combination of germaben ii with methyl paraben and propyl paraben 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.
