Embodiment 1

[0019] (1) After the mature seed melon is deseeded, the pulp or the pulp of the skinned melon is mechanically pulverized, extracted 3 times with an ethanol solution with a volume concentration of 80% at 50° C., and filtered to obtain the supernatant; the weight of the ethanol solution is Melon pulp or 10 times the pulp with skin;

[0020] (2) Extract the supernatant obtained at room temperature three times with n-butanol, and concentrate with vacuum rotation to obtain a paste;

[0021] The weight of n-butanol is 5 times of the supernatant;

[0022] (3) At 50°C, add water to the above-mentioned paste to dissolve the paste. The weight of water added is 4 times that of the paste. In order to speed up the dissolution, put it into an ultrasonic generator for dissolution , and then filtered, the filtrate was collected, concentrated in vacuo, and dried to obtain the seed melon extract.

Embodiment 2

[0024] (1) After the mature seed melon is deseeded, the pulp or the pulp of the skinned melon is mechanically pulverized, extracted 3 times with an ethanol solution with a volume concentration of 80% at 50° C., and filtered to obtain the supernatant; the weight of the ethanol solution is Melon pulp or 3 times the pulp with skin;

[0025] (2) Extract the supernatant obtained at room temperature three times with n-butanol, and concentrate with vacuum rotation to obtain a paste;

[0026] The weight of n-butanol is 2 times of the supernatant;

[0027] (3) At 25°C, add water to the above-mentioned paste to dissolve the paste. The weight of water added is 2 of the paste. In order to accelerate the dissolution, put it into an ultrasonic generator for dissolution, Then filter, collect the filtrate, concentrate in vacuo, and dry to obtain the seed melon extract.

Embodiment 3

[0029] The following are percentages by weight:

[0030] Liquid Soap:

[0031] Sodium Polyoxyethylene Laureth Sulfate 17%

[0032] Betaine Lauryl Dimethylaminoacetic Acid 7%

[0033] EDTA-K 2 0.2%

[0034] The seed melon extract of embodiment 1 1.7%

[0035] Deionized water Add to 100%

[0036] The comparison formula is that no seed melon extract is added, and the others are the same as above.

[0037] In the corresponding comparative test, the left hand of the test subject used Example 1 for bathing, while the right hand used the comparative formula for bathing, and washed twice a day. After 30 days, the skin on the back of the left hand of the test subject was obviously softer than the skin on the right hand. smooth.

Abstract

The invention discloses a seed melon extract and a cosmetic comprising the same. The seed melon extract is obtained through the following method: (1) removing seeds from a mature seed melon, crushing melon pulp or the melon pulp with skin, extracting at 25-75 DEG C by using a volume concentration of 75-85%, filtering to obtain supernatant; (2) extracting the supernatant obtained in the step (1) at room temperature by using normal butanol, and condensing the extractive matter under vacuum to obtain paste; and (3) adding water into the paste at 25-50 DEG C, dissolving the paste, filtering, collecting filtrate, condensing under vacuum, and drying to obtain the seed melon extract. The seed melon extract can be used for cosmetic additives, such as human body liquid cleaning products, hair care products or skin care products. The cosmetic of the invention is nutritive, preserves moisture for the skin of human body, and is capable of promoting skin metabolism, improving skin scars, inhibiting pigmentation and resisting aging. After the cosmetic is used, the skin is obviously soft and smooth.

Description

technical field [0001] The invention relates to a seed melon extract and cosmetics containing the seed melon extract. Background technique [0002] Seed-using Watermelon is a special variety of watermelon, which abounds in Northwest China, and Gansu is one of the main producing areas of watermelon. There is a record of using it as medicine in the ancient medicine book "Materia Medica Qiuzhen". It is a plant with the same origin of medicine and food. According to analysis, the pulp and skin of seed melon are rich in various nutrients, such as amino acids, sugars, trace elements, etc., and are easily absorbed by the human body. [0003] For a long time, melon farmers planted melons only for seeds, and the pulp and rind, which accounted for about 95% of the total mass of melons, were discarded as waste, which not only caused a serious waste of resources, but also brought serious damage to soil and water sources. pollute. [0004] According to relevant data records, the conte...
