Embodiment 1

[0029] The lyophilized powder preparation method of the present embodiment is as follows:

[0030] (1) Weigh the material according to the following formula for preparing the lyophilized powder containing oligopeptide-1:

[0031] Water: 83%; Oligopeptide-1: 10%; Mannitol: 7%;

[0032] (2) Mix water and mannitol, raise the temperature to 75° C., stir and mix evenly, and cool down to obtain a mixed material body;

[0033] (3) Cool down the mixed material body to 40°C, add oligopeptide-1, stir and mix evenly, and continue to cool down;

[0034] (4) After the material cools down to 30°C, pour the material body into a glass bottle, and take it out of the pot after being frozen and sublimated.

[0035] The freeze-dried powder prepared in this example has better shaping effect.

Embodiment 2

[0037] The lyophilized powder preparation method of the present embodiment is as follows:

[0038] (1) Weigh the material according to the following formula for preparing the lyophilized powder containing oligopeptide-1:

[0039] Water: 89%; Oligopeptide-1: 5%; Mannitol: 6%;

[0040] (2) Mix water and mannitol, raise the temperature to 80° C., stir and mix evenly, and cool down to obtain a mixed material body;

[0041] (3) Cool down the mixed material body to 45°C, add oligopeptide-1, stir and mix evenly, and continue to cool down;

[0042] (4) After the material cools down to 35°C, pour the material body into a glass bottle, and take it out of the pot after freezing and sublimating.

[0043] The freeze-dried powder prepared in this example has better shaping effect.

Embodiment 3

[0045] The lyophilized powder preparation method of the present embodiment is as follows:

[0046] (1) Weigh the material according to the following formula for preparing the lyophilized powder containing oligopeptide-1:

[0047] Water: 87%; Oligopeptide-1: 5%; Mannitol: 8%;

[0048] (2) Mix water and mannitol, raise the temperature to 78°C, stir and mix evenly, and cool down to obtain a mixed material body;

[0049] (3) Cool down the mixed material body to 43°C, add oligopeptide-1, stir and mix evenly, and continue to cool down;

[0050] (4) After the material cools down to 32°C, pour the material body into a glass bottle, and take it out of the pot after freezing and sublimating.

[0051] The freeze-dried powder prepared in this example has better shaping effect.

Abstract

The invention discloses a formula for preparing freeze-dried powder containing oligopeptide-1. The freeze-dried powder comprises, by weight percentage, 80-92% of water, 3-10% of oligopeptide-1 and 5-10% of mannitol. The invention also discloses a preparation method of the oligopeptide-1. The method comprises the following steps that water is mixed with mannitol, the temperature is increased to 75-80 DEG C, the materials are uniformly stirred and mixed, and cooling is conducted to obtain a mixed material body; the mixed material body is cooled to 40-45 DEG C, the oligopeptide-1 is added, uniformly stirred and mixed, and cooling continues; after the material is cooled to 30-35 DEG C, the material body is poured into a glass bottle, and the glass bottle is taken out of a pot after freeze-sublimation. The formula of the freeze-dried powder containing oligopeptide-1 is simple in structure, reasonable in ratio, good in forming effect and remarkable in repairing effect.

Description

technical field [0001] The invention relates to the field of freeze-dried powder, in particular to a formula and method for preparing freeze-dried powder containing oligopeptide-1. Background technique [0002] Freeze-dried powder is a sterile powder made by ultra-low temperature freezing process under vacuum conditions, and it is a beauty product with repairing effect. When using freeze-dried powder cosmetics, it needs to be used in conjunction with the water solution that dissolves the freeze-dried powder. When the existing freeze-dried powder water solution is used in conjunction with the freeze-dried powder cosmetics, it can effectively improve skin dullness, reduce Pigmentation. The existing freeze-dried powder products on the market, due to the unreasonable design of the composition ratio and process conditions, lead to the loose structure of the freeze-dried powder product, poor product efficacy, high moisture content and poor stability, which affect the repair effec...
