soap kojic acid glutathione & Skin Brightening (2 Bars) blushlin Skin Brightening Soap with

and step 3: stirring to dissolve and clarify the prepared solution, adding water for injection to full amount, and adjusting pH to 6.8 with 10% sodium hydroxide solution

In order to achieve the purpose, the technical scheme of the invention is as follows: the high-stability reduced glutathione for injection is characterized in that: when the amount of the reduced glutathione is 0.6g, the formula components are as follows: reduced glutathione 0.6g Adjusting the pH of the solution to 6.0-7.0 with 10% sodium hydroxide solution Adding water for injection to 2g When the amount of the reduced glutathione for injection is 1.0g, the formula components are as follows: reduced glutathione 1.0g Adjusting the pH of the solution to 6.0-7.0 with 10% sodium hydroxide solution Adding water for injection to 3.3g When the reduced glutathione for injection is 1.5g, the formula components are as follows: reduced glutathione 1.5g Adjusting the pH of the solution to 6.0-7.0 with 10% sodium hydroxide solution Adding water for injection to 5.0g Wherein, in the liquid preparation process, nitrogen is continuously filled in the liquid preparation and filling processes to keep the oxygen content in the solution below 1.5 ppm
