The remaining indicators in line with the standard version of the British Pharmacopoeia BP98
Solubility: soluble in water (25 weight / volume / 25 ℃) and polar organic solvents. Low solubility in oil, 23 ℃, only to dissolve 0.5g, oil / water partition coefficient.
Safety performance:
Acute toxicity: LD50 is 222mg/Kg weight (female oral) -266mg/kg weight (male oral), male and female mice were no significant differences in toxicity tests. Consistent with the foreign literature reports. Moderate level of toxicity in the toxicity.
To the skin and mucous membranes Test: When the concentration is less than 0.5% Bronopol concentration on the skin and mucous membranes without any stimulation. When Buluoboer 0.5% dilution (10-fold higher concentration), a one-time rabbit skin irritation test, the result is a light irritation.
Skin allergy test: When Buluoboer concentration of less than 0.25%, no contact allergy.
Buluoboer inhibitory spectrum
When the presence of organic cosmetics, non-ionic, nonionic surfactants yin and yang, did not affect the inhibitory effect Buluoboer, nor antagonism to each other. Protein content in the formulation is less than 10%, the excellent effect can Bronopol corrosion.
And amount of use of
Broken Ball can be used in creams, lotions, shampoos and other products. General dosage 0.02-0.05% in cosmetic products, the maximum allowable dosage of 0.1%, no residual emissions will not cause accumulation of pollution.
Application PH value range :4-10
Usage: biocides, sterilization is mainly used for industrial water recycling, pulp and paper, paints, plastics, cosmetics, timber, cooling water systems, and industrial uses, mildew, corrosion, algae and so on. Under alkaline conditions, it is easy to lose activity. The most suitable range of Ph 4-6
