Description

A kind of konjac glucomannan eye patch and preparation method thereof

technical field

The invention relates to a cosmetic and a preparation method thereof, in particular to a konjac glucomannan eye patch and a preparation method thereof.

Background technique

With the advent of the Internet age, some office workers have to face the computer for a long time, which makes the eyes bear an unprecedented burden, which will cause dry eyes, soreness and other eye fatigue phenomena; Eye problems such as eye circles and bags under the eyes. These eye problems not only affect the beauty of the eyes to a certain extent, but also lead to eye diseases such as dry eye syndrome and exposure conjunctivitis in the long run. Eye patch has gradually become the focus of people's attention because it can effectively play an anti-oxidation and anti-aging effect, thereby effectively alleviating eye problems. There are a variety of eye patch products on the market, but most of these products enhance a special effect by adding some chemical substances, and these chemical substances are likely to cause more serious eye diseases such as contact dermatitis and allergic reactions. In addition, some products have poor moisturizing durability and cannot effectively solve the problem of skin dehydration. Therefore, under the premise of the concept of green environmental protection and people's higher requirements for cosmetics, it is of great significance to seek a pure natural raw material that is safe, stable, excellent in performance, and non-toxic and side effects to replace these chemical substances, and konjac glucan Glycans were exactly the raw material we were looking for.

Because konjac glucomannan has excellent biological activity and rheological properties such as antibacterial, water absorption, anti-oxidation and film-forming properties, it can prevent skin dehydration and alleviate aging problems, and has become one of the main natural raw materials for cosmetics . Konjac glucomannan and other products have been successfully developed at present, and the present invention is to use konjac glucomannan in the preparation of eye patches, and use the excellent properties of konjac glucomannan to protect the eyes. care.

The invention patent "eye film" with application number 200780013857.5 (application date: 2007/06/01) introduces an eye film. The product can reduce the sagging and fine lines around the eyes caused by the slowing down of metabolism, so as to keep the skin healthy; and it can massage around the eyes at the same time and shorten the required time to meet the needs of users. However, this product realizes these functions by adding certain chemical substances, and does not add some substances with better moisturizing properties to solve the problem that the skin is prone to dehydration. Therefore, problems such as skin allergies and dermatitis are not really solved, and the problem of skin dehydration cannot be solved.

The invention patent "anti-wrinkle elastic eye patch" (application date: 2009/05/18) with application number 200910039541.4 introduces an anti-wrinkle elastic eye patch. Its cosmetic substances include carboresin, glycosolamine, anteline 2-based cellulose, sodium hyaluronate, allantoin, witch hazel distillate, paraben, Vb3, glycerin, plant extracts and purified water. The plant extracts include EYELISS polypeptide components, PHYTOLIGHT complex extracts and CULCKLIFT xanthan gum polymers, and add nano-gold and platinum flakes, which can have anti-oxidation and aging effects without toxic side effects. It can effectively reduce skin diseases caused by chemicals, but this kind of eye patch does not have high requirements for moisturizing and persistence, so it still cannot solve the problem of skin dehydration.

Contents of the invention

In view of the deficiencies in the prior art, the purpose of the present invention is to provide a konjac glucomannan eye patch with reasonable formula, easy to use, fast absorption by the skin and long-term water retention, no toxic and side effects on the eye skin and its preparation method. 

In order to achieve the above object, the technical scheme of the present invention is: a kind of preparation method of konjac glucomannan eye patch, it is characterized in that operating steps are as follows:

(1) Preparation of konjac glucomannan mixture: Add 0.01-1g of konjac glucomannan and 0.01-1g of soybean protein isolate into two 100ml beakers filled with 5-50ml of olive oil respectively, and place them in Heat in a water bath at 85-95°C for 20-40 minutes, combine the solutions in 2 beakers with stirring while pouring until it becomes thick; pour 3-30g of melted beeswax into the thick liquid, Stir well to make konjac glucomannan mixture, set aside;

(2) Preparation of membrane solution: After cooling the konjac glucomannan mixture in step (1) to 45°C, add 0.1-0.5g of collagen, 1-5ml of glycerin and 0.01-1g of monoglyceride, Mix well, and use 1mol/L sodium bicarbonate solution to adjust the pH of the mixed solution to 7-8, stir evenly and let it stand for 6-18 hours to make a membrane solution for later use;

(3) Membrane production: Take 3-5ml of the membrane liquid from step (2) and pour it into the mold for film-making, put the membrane liquid in the mold together with the mold in a drying oven, and dry at 58-60°C for 2-4 hours , take it out, cool to room temperature, and remove the film.

The olive oil and glycerin are liquid; the konjac glucomannan, soybean protein isolate and collagen are powder; the beeswax and monoglyceride are solid.

The present invention has the following advantages: the preparation method of a kind of konjac glucomannan eye patch of the present invention is simple, wherein konjac glucomannan has excellent biological activity and rheological properties, such as antibacterial properties, water absorption, cohesiveness, Anti-oxidation and film-forming properties, etc., have a good protective effect on the skin, prevent skin dehydration, and relieve aging problems; soybean protein isolate contains a variety of essential amino acids and trace elements for the human body, and has high nutritional value and Health benefits, along its peptide chain backbone, contains many polar groups. Therefore, it has good water absorption, gelation, water retention and swelling properties, and plays the role of emulsification, moisturizing and penetration; olive oil is rich in squalene and essential fatty acids with excellent skin affinity, and absorbs quickly , effectively maintain skin elasticity and moisture; beeswax has natural antibacterial properties, and is a natural moisturizer that can form a protective film on the skin surface; collagen, as a very effective cosmetic raw material, is composed of 19 amino acids The natural protein is similar to the structure of human skin collagen, has low antigenicity, good biocompatibility, and has moisturizing, nourishing, firming, anti-wrinkle and other effects; glycerin can improve moisturizing effect; monoglyceride can The effect of emulsification is to fully mix the macromolecular substances, and to combine them more tightly, which is conducive to film formation. The konjac glucomannan eye patch prepared by the preparation method of the invention has the advantages of water retention, anti-wrinkle, natural and no side effects, and the like. the
