Examples
Embodiment 1
[0030] Whitening and anti-freckle composition: 0.01% of rhEGF freeze-dried powder, 40% of North American witch hazel extract, 35% of wax gourd skin water extract and 24.99% of licorice ethanol extract.
[0031] Wax gourd rind extract is made by beating fresh winter gourd rind, extracting once with water at a material-to-liquid ratio of 1:5, extracting for 1 hour each time, filtering the extract, and concentrating the filtrate to an extract with a relative density of 1.10 at 50°C , that is.
[0032] Glycyrrhiza ethanol extract is obtained by crushing licorice root, adding 70v% ethanol to extract for 1 hour according to the ratio of solid to liquid ratio of 1:5, filtering the extract, and concentrating the filtrate to an extract with a relative density of 1.10 at 50°C. .
Embodiment 2
[0034] Whitening and anti-freckle composition: 0.05% of rhEGF freeze-dried powder, 20% of North American witch hazel extract, 50% of wax gourd skin water extract and 29.95% of licorice ethanol extract.
[0035] Wax gourd rind extract is made by beating fresh winter gourd rind, adding water to extract 3 times according to the ratio of material to liquid 1:10, each time for 3 hours, combining the extracts, filtering, and concentrating the filtrate to 50 °C when the relative density is 1.30. Ointment, that is.
[0036] Glycyrrhiza ethanol extract is obtained by crushing licorice root, adding 90v% ethanol to extract 3 times according to the ratio of solid to liquid ratio of 1:10, extracting for 3 hours each time, combining the extracts, filtering, and concentrating the filtrate to 50°C when the relative density is 1.30 extract, ready to use.
Embodiment 3
[0038] Whitening and anti-freckle composition: 0.03% of rhEGF freeze-dried powder, 30% of North American witch hazel extract, 40% of wax gourd skin water extract and 29.97% of licorice ethanol extract.
[0039] Wax gourd rind extract is made by beating fresh wax gourd rind, adding water to extract 2 times according to the ratio of material to liquid ratio of 1:8, extracting for 2 hours each time, combining the extracts, filtering, and concentrating the filtrate to 50°C when the relative density is 1.20. Ointment, that is.
[0040] Glycyrrhiza ethanol extract is obtained by crushing licorice root, adding 80v% ethanol to extract twice according to the ratio of solid to liquid ratio of 1:6, extracting for 2 hours each time, combining the extracts, filtering, and concentrating the filtrate to 50°C when the relative density is 1.15 extract, that is.
