Problems solved by technology

At present, there are few researches on the application of oat germination in cosmetics. Patent CN201010130697.6 involves an oat extract, which is obtained by enzymatic hydrolysis of water extraction amylase, and has long-term moisturizing properties; patent CN201510291087 .7 relates to a kind of oat sprout extract and its application. The extract is obtained by compound extraction and extraction of oat sprouts germinated for 4 days by water and polyols, and the extract has the functions of whitening, moisturizing and firming skin efficacy; there are no literature or patent reports on the anti-allergic, irritation-relieving and antipruritic effects of oat sprouts
[0009] In recent years, due to its rich active ingredients and its efficacy, the cosmetic application of oat extract as a raw material has gradually increased, but the utilization of oat sprouts has been seldom

preparation example Construction

[0029] The present invention provides a kind of preparation method of oat sprout extract, and its preparation comprises the following steps:

[0030] a) providing oat seeds;

[0031] b) germination, respectively germination for 1-7 days, to obtain oat germination;

[0032] c) hot air drying, normal temperature ultrasonic extraction;

[0033] d) filtering the extract obtained in step c);

[0034] e) concentrating the filtrate obtained in step d), and evaporating the solvent to obtain an oat sprout extract.

[0035] In some specific embodiments, step a) comprises washing oat seeds. For example, oat seeds can be washed with water (eg, purified water, deionized water, etc.). After washing, the seeds that float to the top can be removed, leaving the seeds that settle to the bottom. Subsequent germination steps use these bottom-settled seeds.

[0036] The oat seeds described in the present invention are husk oats, and the place of origin is Jeollabuk-do, South Korea, and the s...

specific Embodiment approach

[0073] None of the literature mentions that oat germ extract has the effect of alleviating skin irritation and / or skin itching, nor does it mention adding it to cosmetics as an additive to relieve skin irritation and / or alleviating skin itching. Therefore, the present invention proposes for the first time that the oat germ extract has the effect of relieving skin irritation and / or skin itching, and at the same time, the extract can also be added as a functional additive to external skin preparations, especially cosmetics.

[0074] The present invention is further described below in conjunction with specific examples. However, it should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. The test methods for which specific conditions are not indicated in the following examples are generally in accordance with conventional conditions, or in accordance with the conditions suggested by the manufac...

Embodiment 1

[0079] Embodiment 1: the preparation of oat germination extract

[0080] After the oat seeds are washed with purified water, the seeds floating on the water surface are removed, and only the seeds that settle at the bottom of the water are used. The germination conditions are as follows: the temperature is 20±5°C, the relative humidity is 80%, and the germination is under shading conditions. During this period, the seeds are prevented from drying out, and purified water is continuously provided to give the seeds sufficient moisture and nutrients. After 24 hours of germination, 5 seeds were randomly selected to measure the germination length with a ruler. Take an appropriate amount of oat germination, dry it with a hot air dryer (50°C), use 10 times the amount of 70% ethanol (volume concentration), ultrasonically extract it at room temperature (25±5°C) for 3 hours, filter it with filter paper (HYUNDAI No.53), and keep it at 45°C The solvent was evaporated under reduced pressur...

The invention also discloses application of the oat sprout extract in the aspects of relieving skin irritation and skin itching.

Description

technical field [0001] The invention belongs to the field of cosmetic preparation, and in particular relates to a preparation method of an oat sprout extract and the use of the extract for skin care. The present invention specifically relates to the application of the oat germ extract in relieving irritation and antipruritic cosmetics. Background technique [0002] In recent years, due to the deterioration of the ecological environment and the abuse of various industrial additives, the number of allergic people has increased year by year, and skin allergies have become a major factor affecting human health. Sensitive skin is a special skin type, which means that when the skin is stimulated by the outside world, it is prone to objective symptoms such as erythema, papules, and telangiectasia, accompanied by subjective symptoms such as itching, tingling, burning, and tightness. The main characteristics of sensitive skin are drier, more prone to tightness and redness, mild stim...
