An introduction to betaine
 
Betaine is no stranger to everyone. Betaine is also known as trimethylglycine. It is an all-natural, edible amino acid base that can be used in food fermentation. It is naturally present in many plants such as beets, spinach, malt, mushrooms and Fruits, etc., also exist in lobster, squid, and aquatic crustaceans, including in human liver. Such cosmetic grade betaine is mostly extracted from beetroot molasses by chromatographic separation technology. It is a fast-absorbing, active base that is generally considered to be an intermediate product of the metabolism of living organisms and may participate in the synthesis of methionine as a methyl donor.
 
2. Application of betalain in personal care products
 
The hydrogen atom of the carboxyl group in betaine forms a strong hydrogen bond, which changes the N atom in the water alkaloid and attracts the negative charge. Betaine is also easily replaced by another-molecular water, which means that it stays for a shorter time than other humectants. Unlike many other true carriers, it easily releases water molecules into the surrounding environment when physical conditions change, allowing water to be fully utilized by living cells.

3. Can relieve stress

Modern research has shown that betaine mainly has the ability to rapidly improve skin and hair, has unique moisturizing and cell membrane protection properties, and can increase the solubility of active ingredients in water. It has been widely used in reducing the irritating alkali of sex agent or fruit acid to the skin. Personal care products such as skin care products, shampoo products and oral care products

4. Unique moisturizing and protecting cell membrane properties
 
Organic osmolyte is to protect the internal metabolic activity of cells, resist osmotic pressure, acid and derivatives, etc. Betaine is a major organic osmotic. Scientific research has shown that betaine content in biological cells in environments with high dryness or salt content The more skin cells accumulate or release organic osmotic substances to change the concentration and volume of osmotic substances inside the cells, and the osmotic pressure, such as dehydration of the skin epidermis or exposure to ultraviolet rays, will cause the increase of osmotic substances in skin cells, resulting in apoptosis of epidermal cells and alkali osmotic substances. It can obviously inhibit the alkaline care products, that is, as an organic permeable substance, through the penetration of the stratum corneum of the skin, it can achieve the osmotic balance of protecting cells and increase the water content of the superficial skin. The unique moisturizing mechanism of betaine makes it more commonly used than sodium hyaluronate, betaine can still have a long-lasting moisturizing effect even at very low concentrations. The ⅥCHY moisturizing deep moisturizing product of French L'Oreal Company has added the tap water. The deep moisturizing advertisement claims to attract the deep moisture of the skin to the dehydrated epidermis, so that the superficial skin contains sufficient water.

5. Reduce the irritating effect of detergents and fruit acids
 
Betaine also has anti-allergic and skin irritation-reducing effects in 1% sodium lauryl sulfate (SLS, K12) and 4% cocamidopropyl betaine (CAPB base (Bet) solution and then measured its transdermal water flow results see The irritation of the cavity mucosa. According to the anti-allergy of betaine, in the anti-dandruff shampoo product of anti-dandruff agent, by adding betaine, the irritating effect of surfactant to scalp is obviously reduced, and scalp itching and dryness after washing are effectively improved. At the same time, it can improve the wet combing effect of hair, prevent hair from tangling, and can also be used in hair care and hair care products. A group of interesting experiments such as milk, shower gel, shampoo and emulsifier also proved that although the betaine solution is weakly acidic (1% betaine fruit indicates that betaine can slow down the solution, see Figure 4 for the production of mild fruit acid skin care products, Thereby, it can significantly improve the skin irritation and allergy caused by the low pH value of the fruit acid type anti-aging care acid.

6. Solubilizing properties of betaine
 
It has been shown that 50% betaine solution can dissolve 2% urotaxin at room temperature, which is four times the solubility of urotaxin in pure water. In this way, the betaine is first dissolved in deionized water, a 50% betaine solution is prepared, and then urea is added, fully stirred until it is completely dissolved, and then the remaining amount of deionized water is added. In 50% betaine aqueous solution, the solubility of salicylic acid can be improved at room temperature

7. Betaine based on the above-mentioned summary
 
Betaine has unique properties of linking water and protecting cell membranes and has many excellent functions, such as ability, anti-surfactant irritation, acid buffering ability, good skin feel and specific dissolution. It is non-allergic and has a high degree of biocompatibility, and the market of nursing products will have broad prospects.
