同仁同意（净值）： +1
同仁同意（净值）： +1high activity coefficient at low concentrations 说明： See examples from Wikipedia: 1. "An activity coefficient is a factor used in thermodynamics to account for deviations from ideal behaviour in a mixture of chemical substances......Deviations from ideality are accommodated by modifying the concentration by an activity coefficient" 2. "Specific ion Interaction Theory (SIT theory) is a theory used to estimate single-ion activity coefficients in electrolyte solutions at relatively high concentrations" |

The dermatological uses of Azelaic acid are related to its anti-sebhorreic, anti-mycotic and anti-acne properties. However, its limits in topical formulations are well known, even when it is used at lower concentrations than the pharmacological ones. Firstly, a high percentage amount is required to be effective. Secondly, being insoluble at high concentrations, it provides poor cosmetic properties to the formulations, which result to be thick and difficult to spread over the skin. Finally, its solubilisation by adequate chemical methods (e.g. neutralisation) brings to loss of Azelaic acid content during shelf life, as it decarboxylates. In order to overcome these problems a new molecule, Potassium Azeloyl di-Glycinate, has been produced. It exhibits very high water solubility, high specific activity at low concentration, low toxicity and adequate chemical stability and compatibility. Serial cosmetic efficacy essays have been carried out with informed volunteers. The preliminary results are very interesting. It proved very effective as skin whitening agent and sebum normalizer. In addition, other skin parameters like moisturization and some elastic properties show remarkable improvements. High activity even at low concentrations Study found that after the introduction of azelaic acid glycine... has a high water solubility, lhigh specific activity at low concentration, low toxicity and excellent chemical stability, making azelaic acid can be more widely used in the field of cosmetics industry. -------------------------------------------------- Note added at 25 mins (2016-02-18 02:10:39 GMT) -------------------------------------------------- I see you still fighting with your acne-related files.
