Physical characteristics: 
White crystal power, little water – soluble(1.3g/100ml), easily dissolved in ethane and chloroform. 
MNB unique advantage:
 Based on MSB, combined with niacinamide molecular group, MNB has higher stability and bioactivity. It also saves the separate quantity of the addition of niacinamide.
