Abstract
Description
technical field
[0001] The invention belongs to the technical field of cosmetics, and in particular relates to a cocktail method double-color freeze-dried powder and a preparation method thereof. Background technique
[0002] At present, there are nearly 30 freeze-dried powder manufacturers in China, and their freeze-dried powder products simply add one or two functional ingredients, and the powders are all of a single color (white or colored). The lyophilized powder currently on the market has the following disadvantages: (1) due to the simple added functional components, the effect is not durable; (2) due to the simple added functional components, the effect is not comprehensive; (3) due to the single color of the powder, poor vision .
[0003] Polypeptide freeze-dried powder is a new skin care product developed in recent years, which is safe and effective. Its production method can be simply described as: filling the prepared aqueous solution into a vial and other conta...
Examples
Embodiment 1~3
[0031] See Table 1 for the raw material formula of the cocktail method double-color freeze-dried powder described in Examples 1-3, see Table 2 for the raw material formula of excipient A, and see Table 3 for the raw material formula of excipient B.
[0032] The preparation method of the cocktail method double-color freeze-dried powder described in Examples 1-3 comprises the following steps:
[0033] (1), the raw materials of the upper layer freeze-dried powder and the lower layer freeze-dried powder are respectively prepared into an upper layer freeze-dried powder solution and a lower layer freeze-dried powder solution;
[0034] (2), the lower layer of freeze-dried powder solution is first injected into the packaging bottle, and then the upper layer of freeze-dried powder solution is injected into the packaging bottle for freeze-drying treatment:
[0035] a. Lower the temperature to -44°C and keep it for 10 minutes;
[0036] b. Heat up to -35°C within 20 minutes, and keep at ...
Embodiment 4
[0053] The freeze-dried powders prepared in Examples 1-3 and Comparative Example were placed for 0, 6 months and 12 months respectively, dissolved in water, and the time required for complete dissolution was tested. The test results are shown in Table 4.
[0054] The dissolving time of the lyophilized powder that table 4 embodiment 1~3 and comparative example make
[0055]
[0056] As can be seen from the results in Table 4, the freeze-dried powder described in Examples 1 to 3 can still be dissolved in water quickly after being placed for 12 months, while the freeze-dried powder described in Comparative Example needs to be dissolved in water after being placed for 12 months. It takes a long time to completely dissolve, indicating that the formula of the two-color freeze-dried powder of the present invention is more stable and can be stored for a long time.
