Abstract

Abstract:

The pH, foam volume and foam stability of alkyl glucoside （APG） compounded with six other foaming agents including sodium dodecyl sulfate （K12）, sodium lauroyl sarcosinate （LS-30）, sodium cocoyl glutamate, sodium methyl cocoyl taurate, biological glycolipid and capryl/capramidopropyl betaine in a ratio of 1∶1 in the toothpaste ternary solution of common proportion were studied. Based on this, ordinary calcium carbonate toothpaste and silica toothpaste were made. The foam volume of each toothpaste was measured by Ross-Miles foam analyzer. The pH of each toothpaste was also measured. The foam height of the toothpaste during the stirring process with agitator was measured. Then, the dense foam test was carried out to compare with the toothpaste using sodium dodecyl sulfate as foaming agent. In addition, the foam volume and foam height of several commercial high-foam toothpastes were tested to compare with the self-made silica toothpastes. By these methods above, the foam properties of the self-made toothpaste containing APG compounded with other foaming agents were evaluated. The results indicate that, when APG is combined with K12, LS-30, sodium methyl cocoyl taurate and biological glycolipid, respectively, the foam amount, foam stability and foaming speed are increased for corresponding calcium carbonate and silica toothpastes. Meanwhile, the pH values of toothpastes are in the ideal range under other components’ buffering.

Key words: dense foam toothpaste, APG, foaming agent compounding
