The content of the invention

The present invention proposes a kind of walnut peel extract and its application.

The technical proposal of the invention is realized in this way：

A kind of walnut peel extract is by core preparing the application of anti-dandruff hair cosmetic, the walnut peel extract Peach rascal adds ethanol and extracted, and filters, and concentrates, and dries, dry extract is made.

Preferably, the mass percent concentration of the ethanol is 70%~95%；The number of times of the extraction is 1~5 time, The time of each extraction is 1~5 hour；It is described to extract by the way of immersion or refluxing extraction to carry out；The second The addition of alcohol is 5~10 times of weight of the green peel of walnut weight.

Preferably, the dry extract adds water, filtering concentrates filtrate, dries, obtains water extract.

Preferably, the addition of the water is 2~5 times of weight of the dry extract weight.

Preferably, the dry extract is splined on macroporous absorbent resin, pure water elution is first used, then it is dense with mass percent The ethanol elution for 70%~95% is spent, ethanol eluate is collected, concentrated, is dried.

Preferably, the model HP-20 of the macroporous absorbent resin.

Compared with prior art, the beneficial effects of the invention are as follows：

Use walnut peel extract for raw material, hair shampoo article is made, there is anti-dandruff and itching-relieving.
