Abstract

The antibacterial activity of toothpastes were examined against Staphylococcus aureus,escherichia coli and pseudomonas aeruginosa,to judge whether toothpaste meet GB.Using antimicrobial effectiveness test to preliminary study on the antibacterial properties of toothpaste(LP,MP,HP,LP-HE,LP-BA),three bacterial concentration of LP were over 106cfu/mL,the others had no growth of bacteria after 14 days,and MP had no growth of bacteria within the 28 days,LP-BA was similar inhibitory effect,but the concentrations of escherichia coli and staphylococcus aureus were 4×104cfu/mL,35×104cfu/mL respectively,as 2nd test,HP and LP-H were similar inhibitory effect,only the concentration of escherichia coli was 1×106cfu/mL,2×106cfu/mL when 2nd test.The LP had no antibacterial property,and the other four toothpastes could effectively inhibit bacterial growth.
