Glycacil™ preservatives are extremely effective fungicides and are recommended for use in shampoos, gels, body washes, creams and lotions. They are typically used in combination with a bactericide.


FormulaProtect™ is a new interactive, online application developed by Lonza that allows formulators to save time and easily identify preservatives that best suit their specific needs. By simply selecting specific formulation criteria such as pH, required spectrum, formulation type, regulatory and organizational approvals, amongst other criteria, the user will be presented with a selection of recommended preservative options along with detailed information on each of them.

This tool will help provide guidance for the preservatives that meet formulator’s marketing needs and that provide the efficacy required throughout the lifetime of the cosmetic product.

You can visit the tool through your web browser by going to the Lonza FormulaProtect™ website.
