Abstract: Disclosed are a cleaning composition containing a surfactant system and its application, which relate to the technical field of cleaning compositions and their preparation. The cleaning composition includes A) alkanoyl taurine salt and B) methyl alkanoyl taurine salt. In the implementation process, the prepared cleaning composition is enabled to be applied to personal care cleaners by controlling the mass ratio of alkanoyl taurine salt to methyl alkanoyl taurine salt, and thus the respective disadvantages of the two raw materials can be overcome and their respective advantages are leveraged. The resulting cleaning product is easier to thicken, high in transparency and good in stability, and has better foaming power and conditioning property.

Abstract: The present disclosure herein provides a synthesis process of fatty acyl taurine salt, belonging to the field of organic chemical synthesis technology. The synthesis process, comprising: adding fatty acid or ester thereof, taurine, and solvent into a reaction vessel, stirring well, and then adding a catalyst, heating the reaction under stirring conditions, and removing the generated water during the reaction, after the reaction being completed, the fatty acyl taurine salt product is obtained. The present disclosure directly uses taurine and fatty acid or ester thereof as raw materials for reaction, and by controlling the type of the catalyst and solvent as well as the reaction temperature, the yield of the product can be significantly improved, and the obtained fatty acyl taurine salt have high purity, low irritation, light color, and strong foaming ability.

Abstract: Disclosed are a brain-computer interface based robotic arm self-assisting system and method. The system comprises a sensing layer, a decision-making layer and an execution layer. The sensing layer comprises an electroencephalogram acquisition and detection module and a visual identification and positioning module and is used for analyzing and identifying the intent of a user and identifying and locating positions of a corresponding cup and the user's mouth based on the user intent. The execution layer comprises a robotic arm control module that performs trajectory planning and control for a robotic arm based on an execution instruction received from a decision-making module.
