ROKONSAL PEM

INCI Name
Propylene Glycol / Methylparaben / Ethylparaben /  Propylparaben

DESCRIPTION
ROKONSAL PEM consists of a combination of Methyl-, Ethyl- and Propylparaben in a glycolic solution. It does not contain Phenoxyethanol, formaldehyde or formaldehyde-releasing substances and conforms to the regulations of the EC cosmetics law.
The parabenes as basic actives of ROKONSAL PEM become deactivated by nonionic or highly ethoxylated surfactants. This fact can give the necessity to adapt the product-formula to the preserving system.

PROPERTIES
The combination of biocides in ROKONSAL PEM predominantly shows a microbiostatic spectrum of activity against gram-positive and gram-negative bacteria. However, at the usual use-levels also growth of fungi and yeast will be inhibited.
