 Additional Information:

 Product Application: Bronopol has extremely broad spectrum activity against Gram-positive and Gram-negative bacteria, yeasts and molds. It is particularly effective against Pseudomonas species.The active ingredient is 2-Bromo-2-Nitropropane-1,3-Diol. It is listed in the USA and the EU respectively as an approved cosmetic preservative at levels up to 0.1%. Bronopol 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%. Bronopol BN is compatible with most cosmetic ingredients such as surfactants, emulsifiers, proteins and natural extracts. It is synergistic with other preservatives such as isothiazolinones,parabens and Iodopropynyl Butylcarbamate (IPBC). 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. Conditions of high temperatures, alkaline and sunlight will cause degradation of the active ingredient. 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.
