Fermentation extracts, cosmetic composition and manufacturing method of fermentation extracts

1 . A fermentation extract consisting of a glutathione liquid dispersion liposomized using a liquid collagen extract as a solvent and a Lactobacillus fermentation filtrate obtained by stirring and extracting the same at a preset low temperature.

2 . The fermentation extract according to claim 1 , wherein the preset low temperature is 25° C.

3 . The fermentation extract according to claim 1 , wherein the liquid collagen extract is extracted at a low temperature of 20° C. by mixing collagen powder, butylene glycol, and purified water at a preset ratio.

4 . The fermentation extract according to claim 1 , wherein the liposomized glutathione liquid dispersion is a dispersion obtained by mixing and stirring purified water and glutathione powder at a preset ratio.

5 . The fermentation extract according to claim 1 , wherein the Lactobacillus fermentation filtrate is a filtrate obtained by mixing purified water, a Lactobacillus fermentation solution, and glycerin at a preset ratio and fermenting.

6 . A cosmetic composition comprising a fermentation extract of claim 1 .

7 . A manufacturing method of a fermentation extract using dual low-temperature extraction and liposomization, the method comprising:

a step of producing a liquid collagen extract at a first low temperature by mixing collagen powder, butylene glycol, and purified water at a preset ratio;

a step of producing a liposomized glutathione liquid dispersion by mixing and stirring purified water and glutathione powder at a preset ratio;

a step of producing a Lactobacillus fermentation filtrate obtained by mixing purified water, a Lactobacillus fermentation solution, and glycerin at a preset ratio and fermenting; and

a step of producing a fermentation extract by stirring and extracting a glutathione liquid dispersion liposomized using a liquid collagen extract as a solvent and a Lactobacillus fermentation filtrate at a second low temperature which is different from the first low temperature.

a step of setting the temperature of an extractor to 20° C.;

a step of placing a mesh screen containing 30 parts by weight of butylene glycol, 65 parts by weight of purified water, and 5 parts by weight of collagen powder into the extractor;

a step of extracting in the extractor for 250 to 300 hours; and

a step of filtering a completely extracted mixture through the mesh screen of 400 mesh to complete a liquid collagen extract extracted at a low temperature.

9 . The manufacturing method of a fermentation extract according to claim 7 , wherein the step of producing a liposomized glutathione liquid dispersion includes:

a step of preparing 90 parts by weight of purified water and 10 parts by weight of glutathione powder;

a step of primarily mixing the purified water with the glutathione in a stirrer for 30 minutes;

a step of producing a homogeneous dispersion by passing the primarily stirred mixed liquid through a ultra-high pressure emulsification process; and

a step of filtering the homogeneous dispersion with a filter screen of 250 mesh to complete a liposomized glutathione liquid dispersion.

10 . The manufacturing method of a fermentation extract according to claim 7 , wherein the step of producing a Lactobacillus fermentation filtrate includes:

a step of producing a Lactobacillus fermentation solution by preparing a Lactobacillus strain, inoculating the same into a liquid medium, maintaining the temperature of the liquid medium at 35 to 40° C., and culturing in an incubator for three days;

a step of adding 50 parts by weight of purified water, 30 parts by weight of the Lactobacillus fermentation solution, and 20 parts by weight of glycerin into a fermenter and fermenting at 37° C. for ten hours; and

a step of filtering the completely fermented product through a mesh screen of 400 mesh to complete a Lactobacillus fermentation filtrate.

11 . The manufacturing method of a fermentation extract according to claim 7 , wherein the step of producing a fermentation extract includes:

a step of setting the temperature of an extractor to 25° C.;

a step of adding 60 parts by weight of a liquid collagen extract as a solvent, 20 parts by weight of liposomized glutathione liquid dispersion, and 20 parts by weight of the Lactobacillus fermentation filtrate into the extractor and mixing;

a step of extracting for 300 hours while performing a stirring process; and

a step of filtering the completely extract through a mesh screen of 400 mesh to complete a fermentation extract.
