Usage Recommendations      

The recommended usage concentration for parabens is 0.2% to 0.5%, with mixed esters up to 0.8%.

Parabens should be the last ingredient added to the formulation, preferably at a temperature ≤60°C. Due to the wide variation in ingredients and formulations of personal care products, which may affect the efficacy of preservatives, we strongly recommend verifying the efficacy and stability of parabens before production.
