The use of plants in cosmetics has a long history. As early as 3,000 to 4,000 years ago, ancient Chinese people began to use plants (including herbs and natural medicines) as cosmetic products for beauty and skin
In recent years, with the improvement of people's living standards and the demand for their own health, a variety of cosmetic products are being paid more and more attention to. Animal proteins have been used in cosmetics for a long time, but in recent years, under the influence of the animal rights movement, their use in cosmetics has been decreasing, and people have turned their attention to plant proteins. Since there are many varieties of plant proteins (especially genetically modified technology makes more varieties), their active ingredients are effective and have few side effects, so natural beauty products based on plant proteins are more and more favored by consumers.
Protein is an important component of the human body, such as skin, hair, nails and a variety of organs are composed of protein. Protein also sustains the activities of life. Therefore, it is widely used in today's cosmetics. The nutritional value of protein depends not only on its content, but also on the abundance and balance of its eight essential amino acids. Protein is an important component of skin and other tissues, promoting growth and development, repairing tissues, and replenishing metabolism. Collagen is an important component of the human connective tissue, with active and biological functions of collagen can actively participate in the migration, differentiation and proliferation of cell metabolism, with the role of linkage, nutrition, support and protection. Human skin contains a large amount of collagen and mucopolysaccharides, which are highly hydrophilic and can retain a large amount of water, making the skin moist, tender, maintain the elasticity and toughness of the skin. Protein is involved in the metabolism of the skin and other tissues, and the loss of protein from the exfoliation of the stratum corneum requires timely replenishment. Lack of protein skin will age and lose elasticity, wrinkles, brown spots, dryness, roughness and so on.
The application of plant proteins in cosmetics is later than that of animal proteins and collagen. Plant proteins have good affinity for skin and scalp, improve skin moisturizing properties, give elasticity to blood vessels and tendons, and have better film-forming properties, being the main component of epidermal and dermal film formation. At the same time, it also improves the tonality of cosmetics. Plant protein contains 8 kinds of essential amino acids (these amino acids cannot be synthesized by human body), which can become skin moisturizing nutrients according to different degrees of hydrolysis. Plant protein derivatives can also change the feel of the skin or hair, increase lubricity, improve solubility of proteins, and enhance the durability of conditioning effects. Hydrolyzed plant protein is generally transparent amber liquid, light odor, with good film-forming properties, the skin has an affinity, feel comfortable after use. Such as foreign production containing colloidal oat protein cleanser, because the colloidal oat protein contains plant protein and lipids, anti-itch, lubrication, moisturizing, anti-allergic effect, favored by users. There are two types of vegetable proteins used in cosmetics, namely hydrolysates of vegetable proteins and derivatives of hydrolysates. Hydrolyzed proteins can be processed by different methods such as enzymatic hydrolysis or acid hydrolysis.
The derivatives of plant proteins are generally prepared by chemically modifying the side chain or the end of the protein by introducing other groups. The relative molecular mass of hydrolyzed plant proteins (peptides) is about 1000-30,000 Da, which have good physiological activity and can be easily absorbed by human body. Many natural plant active proteins have high affinity for skin and hair, are easily absorbed, can improve the moisturizing property of skin, give elasticity to blood vessels and tendons, and have the functions of nutrition, film formation, prevention of aging and promotion of regeneration.
Nowadays, there are many kinds of vegetable proteins used in cosmetics, for example, hydrolyzed protein, hydrolyzed wheat protein, hydrolyzed golden pea protein and hydrolyzed almond protein, etc. In addition, there are a large number of proteins including alcohol soluble protein and modified protein, which cannot be described here.
Soy protein is a class of proteins with high functionality and biological activity. It is well known that the typical functions of soy protein are gelation, foaming, emulsification and acting as a surfactant, and these properties are highly valued by the daily cosmetic industry. Due to the high nutritional properties of soy protein, it is not only a great supplement to the body's nutrition, but also has a very good nourishing effect on the skin and hair. China is one of the major producers of soybeans, soy protein extraction process is already mature
From the price point of view, for the high value-added cosmetics industry, soy protein as raw material is quite reasonable.
Soy protein is mainly divided into soy peptides, soy hydrolyzed protein and soy modified protein. Soy protein by enzymatic hydrolysis of the product has a certain antioxidant capacity, including acid protease hydrolysis of the product has the strongest antioxidant capacity. So after a certain treatment of soy protein isolate for the preparation of cosmetics with antioxidant properties will be a good addition to the composition.
At present, the development of oats is mainly focused on food, its development and application in cosmetics is less research. Foreign research in this area, and there have been related to the oat protein cosmetics market, expensive. For example, the company launched the oat protein extract is the oat protein hydrolysis, so that it is broken into relatively small molecular weight of protein fragments, thus more conducive to skin absorption, promote skin metabolism. In addition, the current general oat bran as raw materials, cheap and easy to obtain, can greatly reduce product costs.
The total amount of amino acids in oat protein is 0. 5435g/100g, and the total amount of essential amino acids is 0. 1981g/100g. 0. 1981g/100g, accounting for 36.45% of the total amino acid content; glutamic acid The highest content of glutamic acid accounted for 18.23%, and the essential amino acids of phenylalanine, leucine and isoleucine were the highest. The content of glutamic acid was the highest, accounting for 18.23%. The amino acid composition analysis showed that the oats had the highest content of glutamic acid. The results of amino acid composition analysis showed that oat The results of amino acid composition analysis showed that the amino acid content of oat protein was rich and balanced, and the proportion of essential amino acids It is a high quality nutritional protein. The water-soluble oat protein and amino acid as an important medium to lock the moisture of the skin important medium to lock the skin moisture, has significant nutritional nourishment and moisturizing effect, especially It is especially suitable for people with dry skin.
The effects of wheat protein in cosmetics are mainly as follows: 1) absorbing into the damaged part of hair to repair damaged hair; 2) significantly enhancing the tensile strength and elasticity of hair fibers; 3) smoothing hair and increasing hair shine; 4) improving foam stability and foam structure; 5) having strong affinity for skin, forming a shiny and smooth protective film on skin; 6) enhancing skin resistance to chemicals and 6) enhance the skin's resistance to chemicals and external environment; 7) reduce the irritation of surfactants to the skin; 8) Reduce the greasy feeling in oily formulations. Wheat protein is insoluble in water and is directly used in cosmetics as a partial hydrolysate, which can be hydrolyzed by enzymes or acids. The relative The wheat protein hydrolysate with the molecular mass of 1000 Da is easily absorbed by the hair, because the hair also contains cystine, and when added to the perm, the wheat protein spreads into protective filaments and retains the shape for a long time; the wheat protein hydrolysate with the relative molecular mass of (2~3) × 10000 Da has strong hygroscopicity and moisture retention. The wheat protein hydrolysate with relative molecular mass (2-3) × 10 4 Da has strong hygroscopicity and moisture retention, and is easy to form a film. wheat protein has good foaming power, the concentration of 1.8 % is the highest, after the concentration of Wheat protein has good foaming power, the concentration of 1.8% is the highest, after the concentration increases the change is very small, there are in the face wash It has been reported to be added in facial cleanser to foam and stabilize the foam; emulsion stability is good, especially wheat protein and The stability of emulsion is good, especially when wheat protein is used in combination with non-ionic surfactants. The stability of the emulsion is good, especially when wheat protein is used with non-ionic surfactants. For example, Letifetto Cosmetics Wheat Protein Conditioner The wheat protein emulsion is easily absorbed by the hair, and the effect is long-lasting and stable. The hair is repaired, balanced and conditioned. The effect of wheat protein is to restore, balance and condition the hair. Wheat protein is currently used in a wide range of applications It is used in a wide range of products, such as shampoos, conditioners, hair conditioners, face washes, body washes, skin care products, etc. It can be found in products such as shampoos, conditioners, hair conditioners, face washes, body washes, skin care products, etc.
Barley protein accounts for 8-13% of the total weight of barley with hulls, the main components are alcohol-soluble protein and glutenin, of which alcohol-soluble protein accounts for 35-45% of the total protein, glutenin accounts for about 35-43% of the protein content of barley. In addition to these two proteins, barley also contains clear protein and globulin. In barley, the protein that can be dissolved in ethanol is called barley gliadin, the amino acid composition of barley gliadin is not as rich as wheat gluten and wheat gliadin, in which the content of threonine, lysine, valine, leucine, tyrosine, aspartic acid are very low, so barley protein is an incomplete protein. However, barley protein content is slightly higher than wheat, corn, rice, etc. Due to the high content, it can make up for the lack of quality. Barley protein is important for the repair and regeneration of cell composition, and can be quickly absorbed into the blood circulation, and can support the normal operation of cells. When barley is added to cosmetics, it can be used to moisturize, nourish and nourish the skin. Hydrolyzed barley protein is rich in a variety of natural nourishing and silky ingredients, which can play a role in nourishing and protecting the skin. At the same time, adding hydrolyzed barley protein to mascara can make the eyelashes
The addition of hydrolyzed barley protein to mascara can make the eyelashes softer, stronger and more beautiful. In hair care, barley protein strengthens and smoothes hair, leaving it silky soft, healthy and more manageable.
Corn alcohol soluble protein has good film-forming properties, moisturizing properties (i.e. water-holding) and antioxidant properties, which makes corn alcohol soluble protein can be added to cosmetics as a moisturizer, and is an ideal natural moisturizer; skin aging is manifested in the loss of skin elasticity, loosening, roughness, wrinkles, age spots and other phenomena, from the physiological point of view, mainly involving the cross-linking and degradation of skin proteins and connective tissue. Two types of reactions, reactive oxygen radicals are a major factor in cross-linking, antioxidants can play an important role by eliminating free radicals.
By eliminating free radicals, antioxidants can play a role in anti-wrinkle; the peptides generated by the enzymatic degradation of maize sol protein have antioxidant properties, and the moisturizing mask made of maize sol protein can remove free radicals and maintain the moisture of the skin, which can effectively reduce cholesterol in the body and promote cell renewal, which is conducive to the removal of aging keratin, making the dull skin bright and elastic, and allowing the skin to enhance the absorption of maintenance products.
