Abstract:

The effects of different mass concentrations of surfactants on the growth of oral probiotics were studied. Six surfactants commonly used in oral care products, i.e. PEG-40 hydrogenated castor oil (RH-40) , PEG-60 hydrogenated castor oil (RH-60) , cocamidopropyl betaine (CAB-35) , sodium lauroyl sarcosinate (LS-97) ,sodium cocoyl glycinate (AK-301) and sodium dodecyl sulfate (SDS) , were used; Weissella cibaria and Streptococcus salivarius were used as experimental probiotic strains. The results of modified Oxford cup method showed that probiotics were all sensitive to the six surfactants with a mass concentration of 10 g/L; the results of broth micro-dilution method showed that different mass concentrations of different surfactants had different effects on oral probiotics. RH-60 with a mass concentration ≤0.078 g/L and RH-40 with a mass concentration ≤0.156 g/L could promote the growth of probiotics; RH-60 with a mass concentration of 0.156-0.625 g/L, CAB-35 with a mass concentration of 0.02 g/L, and LS-97 and AK-301 with mass concentrations ≤0.039 g/L had no significant effect on the growth of probiotics; SDS, LS-97 and AK-301 with mass concentrations ≥0.313 g/L and CAB-35 with a mass concentration ≥1.25 g/L completely inhibited the growth of probiotics. The inhibitory effects of RH-60 and RH-40 with mass concentrations >0.156 g/L on probiotics were weaker than other surfactants at the same mass concentration. Low mass concentrations of AK-301, CAB-35 and LS-97, and each mass concentration of RH-60 and RH-40, could be given priority to be used in oral care products.
