Embodiment 1
[0052] Embodiment 1: the preparation method of longan nucleus superfine powder:
[0053] Put the naturally dried longan kernels in an oven at 60°C for 24 hours at a constant temperature, then let them cool naturally in a dry environment, crush them with a superfine grinder, and pass through a 500-800 mesh sieve to obtain longan kernel superfine powder, which is used in hair dyes Production.
[0054] The preparation method of longan kernel ethanol extract:
[0055] The longan core superfine powder is extracted with a volume fraction of 95% edible ethanol aqueous solution for 3 times with a mass ratio of 1:10, each time for 24 hours, and the combined extracts are filtered for three times, then concentrated under reduced pressure to obtain an extract, and the extract is sprayed Dried or freeze-dried to get a reddish-brown powder, which is the ethanol extract of longan kernel, which is used to prepare hair dye.
Embodiment 2
[0056] Embodiment 2: the preparation method of litchi core superfine powder:
[0057] Put the naturally dried lychee kernels in an oven at 60°C for 24 hours at a constant temperature, then let them cool naturally in a dry environment, crush them with a superfine grinder, and pass through a 500-800 mesh sieve to obtain ultrafine powder of lychee kernels, which can be used in hair dyes Production.
[0058] The preparation method of litchi kernel ethanol extract:
[0059] The superfine powder of litchi core is leached three times with 95% edible ethanol aqueous solution with a volume fraction of 95% at a material ratio of 1:10, each time for 24 hours, and the combined extracts are filtered three times, then concentrated under reduced pressure to obtain an extract, and the extract is spray-dried Or freeze-dried to get a reddish-brown powder, which is the ethanol extract of lychee kernel, which is used to prepare hair dye.
Embodiment 3
[0060] Embodiment 3: the preparation method of mango core superfine powder:
[0061] Place the naturally dried mango cores in an oven at 60°C for 24 hours at a constant temperature, then let them cool naturally in a dry environment, crush them with a superfine grinder, and pass through a 500-800 mesh sieve to obtain superfine mango core powder, which is used in hair dyes Production.
[0062] The preparation method of mango kernel ethanol extract:
[0063] The superfine mango core powder is leached 3 times with 95% edible ethanol aqueous solution with a volume fraction of 95% edible ethanol at a material mass ratio of 1:10, and the combined leaching solution is filtered for three times, then concentrated under reduced pressure to obtain the extract, and the extract is sprayed Dried or freeze-dried to get a reddish-brown powder, which is the ethanol extract of mango kernel, which is used to prepare hair dye.
