AI Technical Summary
Existing methods for extracting olive leaf ingredients primarily use organic solvents, water, or steam distillation, lacking the use of aqueous ethanol solutions to produce distilled extracts for cosmetics, medicated cosmetics, foods, and soft drinks.
Aqueous ethanol solution is used to distill olive leaves from the Oleaceae family, including olive (Olea europaea), with the residue mixed to create a stable extract for incorporation into cosmetics, medicated cosmetics, foods, and soft drinks, using polar solvents and preservatives.
The resulting extract is stable and effective for use in cosmetics, medicated cosmetics, foods, and soft drinks, leveraging olive leaf polyphenols like oleuropein for antioxidant and immune-enhancing properties.
Abstract
Description
[Technical Field]
[0001] The present invention relates to the use of a material obtained by mixing a distillate of leaves of the Olea genus, including olive (Olea europaea), in the Oleaceae family with a residue after distillation as an ingredient for cosmetics, medicinal cosmetics, baking products, foods, processed foods, and soft drinks.
[0002] Traditionally, there have been olive leaf ingredients used in cosmetics, medicated cosmetics, non-prescription products, foods, processed foods, and soft drinks, but these have mainly been extracted with organic solvents, water, or aqueous solutions, or have been essential oils obtained by steam distillation, and no distilled extract materials have been produced using aqueous ethanol solutions. Summary of the Invention [Problem to be solved by the invention]
[0003] The present invention aims to use a material obtained by mixing a distillate of leaves of the genus Olea, which belongs to the family Oleaceae, including olive (Olea europaea), with the residue after distillation as an ingredient for cosmetics, medicated cosmetics, quasi-drugs, foods, processed foods, and soft drinks. [Means for solving the problem]
[0004] The present invention can be obtained by mixing the distillate of an aqueous ethanol solution and the residue after distillation of leaves of the genus Olea, including olive (Olea europaea), in the family Oleaceae.
[0005] The genus Olea of the family Oleaceae, including the olive (Olea europaea) used in the present invention, comprises one or a combination of two or more leaves of Olea capenisis, Olea paniculata R.Br., Olea woodiana Knobl, sea olive (Olea brachiata), etc.
[0006] The leaves of the genus Olea, including olive (Olea europaea), of the family Oleaceae, used in the present invention may be either fresh (excluding withered leaves) or dried, or a combination of two or more of these leaves.
[0007] In the present invention, olive leaves of the genus Olea, including olive (Olea europaea), of the family Oleaceae, can be obtained by distilling either fresh or dried leaves, excluding withered leaves, or a combination of two or more of these leaves, using a polar solvent such as ethanol or isopropanol, either alone or as a mixture.
[0008] The polar solvent used in the distillation carried out in the present invention is a 70 to 90 weight percent aqueous solution.
[0009] The leaves of the Oleaceae family, including the genus Olea, including olive (Olea europaea) obtained in the present invention, can be either fresh (excluding withered leaves) or dried, or a combination of two or more, to be distilled as an extract material, and by adding parabens, dehydroacetic acids, benzoates, phenoxyethanol, 1,3-butylene glycol, hexanediol, and other polar organic solvents and plant-derived ingredients with preservative properties, the extract can be stably incorporated into cosmetics, medicated cosmetics, quasi-drugs, foods, processed foods, and soft drinks. [Effects of the Invention]
[0010] The distilled extract material obtained by the present invention from the leaves of the Oleaceae family, including the genus Olea, including olive (Olea europaea), can be either fresh or dried (excluding withered leaves), or a combination of two or more of these leaves, and can be stably incorporated into cosmetics, medicated cosmetics, quasi-drugs, foods, processed foods, and soft drinks.
[0011] It is generally known that olive leaves characteristically contain polyphenols including oleuropein.
[0012] Oleuropein, as mentioned above, has antioxidant effects such as inhibiting melanin production, promoting collagen production, and strengthening the immune system by preventing infection by viruses and pathogenic microorganisms.
[0013] Due to the effects described above, the extract material obtained from olive leaves is known to be useful as an active ingredient to be incorporated into cosmetics for beauty purposes, medicated cosmetics that maintain and improve skin health, foods and processed foods that enhance immune function, soft drinks, and quasi-drugs.
[0014] Based on the above, existing extract materials obtained from olive leaves are widely used in cosmetics, medicated cosmetics, quasi-drugs, foods, processed foods, and soft drinks. DETAILED DESCRIPTION OF THE INVENTION
[0015] The following describes the implementation of the present invention. [Example]
[0016] Fresh olive (Olea europaea) leaves are disinfected with a 6% solution of sodium hypochlorite diluted 1:100 with water.
[0017] The olive leaves disinfected in the previous section are distilled with an 80% by weight aqueous solution of ethanol.
[0018] The residual liquid after distillation is filtered and mixed with the distilled olive leaf extract obtained in the previous section.
[0019] 0.8 weight percent of phenoxyethanol is added to the mixture of olive leaf distilled extract and residue obtained in the previous section, making it possible to preserve the obtained material as a cosmetic material. [Industrial Applicability]
[0020] The present invention is utilized in the industries that produce cosmetics, medicated cosmetics, quasi-drugs, foods, processed foods, soft drinks, and cosmetics.
