The present invention relates to effervescent compositions which are resistant to water vapour in the atmosphere and to methods of preparing such compositions. In particular, the invention relates to an effervescent composition comprisinga co-crystal. The co- crystal comprises an acidic component and a basic component is separate. The co-crystal comprising the acidic component is resistant to water uptake avoiding initiating the effervescence prematurely. Upon dissolution of the co-crystal and the basic component effervescence occurs.
本发明涉及一种耐大气中
水蒸气的泡腾组合物以及制备这种组合物的方法。具体而言,该发明涉及一种包含共晶体的泡腾组合物。该共晶体包括一个酸性组分和一个碱性组分是分开的。含有酸性组分的共晶体对
水的吸收具有抗性,避免过早引发泡腾。在共晶体和碱性组分溶解后,泡腾就会发生。
