Applications:

The active ingredient of ALT-BNPD is 2-Bromo-2-Nitropropane-1,3-Diol or 
Bronopol. It is listed in the USA and the EU respectively as an approved cosmetic
preservative at levels up to 0.1%.
ALT-BNPD is an excellent preservative for both leave-on and rinse-off products
such as creams, lotions, shampoos, rinses, wipes and towelettes. The recommended
use level is 0.02~0.05%.
1)Its optimum pH range of use is 4~8. It should be added as the last ingredient and at
the lowest temperature (≤50℃) if possible.
2) Conditions of high temperatures, alkaline and sunlight will cause degradation of the
active ingredient. 
3)The presence of a few agents such as sulfhydryl compounds, sulfite, hyposulfite, aluminous
 and ferreous materials will lead to loss of activity. The use of secondary amines should be
avoided in formulations.
