General information

Aquaguard 9093 is compatible with most personal care ingredients.

It is suitable for use in low pH formulations, but will lose efficacy if the pH rises above 5.5.

The product as supplied may change in appearance from yellow to brown on storage, but no further discolouration occurs when it is used in the end product as long as the formulation remains acidic. Aquaguard 9093 should not be used in aerosol dispensers (sprays).
