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 .
