Applications
BIOCROL WS2 is recommended at addition levels between 0,2 - 1% and is stable in a broad range of pH (4 - 9) and compatible with surfactants and protein derivatives. BIOCROL WS2 is very active against gram-negative and gram-positive bacteria and provides a preservative system which can be used to control the pseudomonads in sensitive leave-on applications such as eye liner, lipstick and face creams. BIOCROL WS2 is the ideal preservative system for aqueous based leave-on applications, such as creams and lotions, but is equally efficacious for shampoos, liquid soaps and hair conditioners where mildness is an important feature of the formulation.
Packaging
BIOCROL WS2 is delivered in sealed drums of 25 kg on shrink-wrapped pallets of 600 kg net.
