Desensitizing composite nano emulsion for sensitive skin repair and preparation method thereof

Abstract

The invention relates to the technical field of medicaments and discloses desensitizing composite nano emulsion for sensitive skin repair. The emulsion is prepared from the following raw materials in preferable part by weight: 12.956 parts of isopropyl myristate, 29.4 parts of polyethylene glyceryl caprylate / caprate, 9.8 parts of polyglycerol-3-dioleate, 39.3475 parts of distilled water, 0.495 part of citric acid, 0.6525 part of sodium citrate, 0.005 part of metallothionein, 2.25 parts of daisy extract, 2.25 parts of oxymatrine, 1.246 parts of vitamin E, 0.79 part of chamomile, and 0.79 part of lavender oil. The average particle size of the emulsion is no more than 100 nm. The method greatly improves the skin penetration performance and dispersibility of active ingredients and the extensibility of the product on skin, thereby greatly improving the desensitizing effect of the product. The composite nano emulsion of the invention can be widely used for desensitizing sensitive skins.

Description

technical field [0001] The invention belongs to the technical field of medicine and relates to a new cosmetic preparation with desensitization effect on sensitive skin, in particular to a desensitization composite nanoemulsion for repairing sensitive skin and a preparation method thereof. Background technique [0002] Sensitive skin is a state of highly sensitive skin. In this state, the skin is easily affected by external factors, and discomfort such as skin itching, tightness, burning, and stinging occurs. The survey found that nearly 40% of people think they have sensitive skin. Frosch and Kligman scholars believe that 14% of people with normal skin appearance have hypersensitive skin, 25% have hyposensitive skin, and 61% have normal skin. Sensitive skin, as a skin problem with a high incidence in modern society, affects people's quality of life. With the advancement of society and people's pursuit of beauty, more and more people pay attention to their skin health and q...

Problems solved by technology

[0009] 2. External factors

① External drug treatment, the treatment principle is anti-inflammatory, anti-allergic, anti-itching through external hormone ointment or liquid drug, its advantage is that the symptoms can be quickly relieved in a short period of time, but the side effects are obvious, easy to relapse, resulting in decreased immunity and even serious symptoms. possibility of glaucoma

At present, there are many functional cosmetics on the market to prevent and treat sensitive skin, which are easy to use, but the effect is not obvious due to the skin barrier

② Oral drug treatment, divided into two kinds of traditional Chinese medicine and western medicine. Drug therapy can control the development of the disease within a certain period of time, but the side effects are large, and it is easy to form dependence.

③ Acupuncture and moxibustion in traditional Chinese medicine can be cured through acupoint injection, acupuncture, blood pricking, moxibustion, ear acupuncture, pricking and cupping, etc., but it requires proficiency in techniques. Needle insertion is usually painful, the treatment is complicated, and the course of treatment is generally longer

⑤Four-step immune gene therapy, through the removal of allergens, patient immune repair, symptomatic drug treatment of allergies and inflammation, standardized immunotherapy, expert treatment for specific diseases, quick results, high cure rate, not easy to relapse, no toxic side effects, but this Therapy is only mastered by a few specialized hospitals in China

[0018] 4. Problems of topical products applied to sensitive skin

This makes the current desensitizing cosmetics unable to improve their permeability on the skin surface through some external means, but can only be applied to the skin surface using conventional techniques, which greatly limits the absorption of desensitizing ingredients and cannot reach Theoretical application effect
