|Germaben II is an
ideal preservative system for shampoos, hair conditioners and
emulsion products. Germaben II minimizes the problems associated
with incorporating solid Parabans. 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%. This level provides to the product: 0.30%
Germall II, 0.11% methylparaben, 0.03% propylparaben and 0.56%
propylene glycol. 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.
