General information

Iscaguard 9088 is compatible with most personal care ingredients.

In aqueous formu- lations, heating to 40°C may be required in order to fully dissolve the preservative. However, prolonged exposure to high temperatures should be avoided in order to protect against discolouration.

Iscaguard 9088 works effectively at pH values below 6.5, though for optimal efficacy we recommend that the pH of the finished product is less than 6.

Iscaguard 9088 is not to be used in aerosol dispensers (sprays) according to the EU Cosmetic Regulation.
