The product can be stored for prolonged periods (1-2 years) with practically no loss of activity. It is stable at temperatures of up to 50 °C. At higher temperatures, the pH may be slightly reduced over time. However, this does not affect the application properties of the product.

Depending on the total solids content, crystallization may occur at storage temperatures below 0 °C. Total solids are defined as the total of all solid compounds dissolved in the QUAB solution.

Crystallization points:

QUAB 188 (69 wt.%): below -4 °C (24.8 °F)
QUAB 188 (65 wt.%): below -34 °C (-29.2 °F)
