Embodiment 1

[0059] Example 1 Plant composition 1

[0060] The plant composition formula includes the following raw materials by weight: 5 g of patchouli extract, 5 g of hops extract, and 5 g of rosemary extract;

[0061] 30g PEG-40 hydrogenated castor oil, 10g coco-7, 15g polyglycerol-10 laurate;

[0062] 1,3-Butanediol 20g, deionized water 10g;

[0063] The total amount is 100g.

[0064] The specific preparation method is as follows:

[0065] (1) The stems and leaves of Patchouli are pulverized into powder with a pulverizer, and passed through a 20-mesh sieve to obtain raw material powder for subsequent use. Add the raw powder into deionized 12 times its weight and soak it at room temperature for 3 hours. After the soaking is completed, the temperature is raised to about 100 ° C for distillation, and the distillation time is 4 hours. After the distillate is recovered and stored by the condenser and left to stand for 36 hours, the oil-water two-phase separation is performed, and the o...

Embodiment 2

[0071] Example 2 Plant composition 2

[0072] The plant composition formula includes the following raw materials by weight: 10 g of patchouli extract, 5 g of hops extract, and 5 g of rosemary extract;

[0073] 25g PEG-40 hydrogenated castor oil, 8g cocoeth-7 and 12g polyglycerol-10 laurate;

[0074] 1,4-Butanediol 30g, deionized water 5g;

[0075] The total amount is 100g.

[0076] The specific preparation method is as follows:

[0077] (1) The stems and leaves of Patchouli are crushed into powder with a pulverizer, and passed through a 40-mesh sieve to obtain raw material powder for subsequent use. Using supercritical CO 2 method extraction, the extraction pressure was 18.0Mpa, the extraction time was 3h, and the extraction temperature was 40°C. After the extraction is completed, the extraction mixture is pumped into the separator, and the mixture is separated into gas-liquid two-phase by depressurization, and the liquid phase (oil phase) is the patchouli extract, and 10...

Embodiment 3

[0083] Example 3 Plant Composition 3

[0084] The plant composition formula includes the following raw materials by weight: 8 g of patchouli extract, 5 g of hops extract, and 5 g of rosemary extract;

[0085] 27g PEG-40 hydrogenated castor oil, 10g cocoeth-7 and 10g polyglycerol-10 laurate;

[0086] 2,3-Butanediol 27g, deionized water 8g;

[0087] The total amount is 100g.

[0088] The specific preparation method is as follows:

[0089] (1) The stems and leaves of Patchouli are pulverized into powder with a pulverizer, and passed through a 20-mesh sieve to obtain raw material powder for subsequent use. Add the raw powder into deionized 10 times its weight and soak it at room temperature for 4 hours. After the soaking is completed, the temperature is raised to about 100 ° C for distillation, and the distillation time is 5 hours. After the distillate is recovered and stored by the condenser, the distillate is allowed to stand for 48 hours, and the oil-water two-phase separat...

Abstract

The invention discloses a plant composition for preventing and repairing skin sensitivity. The plant composition comprises the following raw materials in percentage by weight: 0.5-20% of a pogostemon cablin extract, 0.5-20% of a humulus lupulus extract and 0.5-20% of a rosemary extract. The product provided by the invention can quickly and effectively relieve discomfort caused by skin sensitivity, such as stabbing pain, pruritus and the like. The skin sensitive symptoms such as skin discomfort, erythema index, percutaneous water loss rate, skin hydration and the like can be remarkably relieved and improved after long-term use, and the skin barrier function is repaired. Through scientific solvent proportioning and combination, the product has water-oil amphipathicity, can be dissolved in a high proportion in a water phase and an oil phase for use, and can exert the efficacy of the product to the greatest extent according to different application products.

Description

technical field [0001] The invention relates to the fields of biomedicine and cosmetics, in particular to a plant composition for preventing and repairing sensitive skin and a preparation method thereof. Background technique [0002] According to epidemiological studies, the prevalence of sensitive skin in women is as high as 60% to 70%, and in men as high as 50% to 60%. At present, it is generally believed that skin sensitivity does not belong to the category of skin diseases, but a kind of metastable skin. Sensitive skin is characterized by unclear symptoms, unclear causes, and uncertain relief methods. However, when skin sensitivity occurs, it is often accompanied by symptoms such as skin redness, erythema, tightness, abnormal tingling, burning, and itching, which seriously affect the patient's life and social activities, and will bring great psychological distress to the patient. pressure. [0003] Sensitive skin is clinically defined as a series of characteristic sens...
