根据这个作者回复的审稿人意见,PG自己是没有CMC的。所以文献上都是复配胶体的CMC。
All published models for mixed micelles deal with two surfactants. This means calculating excess surface concentration for mixed micelles require cmc of the surfactant and the cmc of the co-surfactant (in our case propyl gallate). In contrast to long-chain alcohols which are able to build small and unstable aggregates, propyl gallate does not exhibit a cmc. Therefore we do not regard propyl gallate as a surfactant but as a solute which is incorporated into the micelle/palisade layer or as cosurfactant as defined by (Skoulios, Ann. Phys. 1978,3:421).

我是看到一篇文献上有这样的描述:A key feature of our approach is the use of short amphiphiles (typically <8 carbon atoms) which exhibit high solubility and high critical micelle concentrations in the aqueous phase. This is a primary requisite to enable the surface modification of a high concentration of colloidal
particles in the liquid phase.【Angew. Chem. Int. Ed. 2006, 45, 3526 –3530】非常感谢你的帮助,将此分享与大家共同交流。
