Betaine‘s function in cosmetics: reduce irritation

Betaine exists in many plantsnaturally , such as beet, spinach, malt, mushroom and fruit, as well as in some animals, such as lobster claws, octopus, squid and aquatic crustaceans, including human liver. Cosmetic betaine is mostly extracted from sugar beet root molasses by chromatographic separation technology, and natural equivalents can also be prepared by chemical synthesis with chemical raw materials such as trimethylamine and chloroacetic acid.

Betaine also has the effects of anti allergy and reducing skin irritation. 4% betaine (BET) solution was added to 1% sodium lauryl sulfate (SLS, K12) and 4% coconut amidopropyl betaine (CAPB), respectively, and its transdermal water shunt loss (TEWL) was measured. The addition of betaine can significantly reduce the skin irritation of surfactants such as SLS. The addition of betaine to toothpaste and mouthwash products can significantly reduce the irritation of SLS to oral mucosa. According to the anti allergy and moisturizing effects of betaine, the addition of betaine in the dandruff shampoo products with ZPT as dandruff remover can also significantly reduce the stimulation of surfactant and ZPT on the scalp, and effectively improve the itching of the scalp and dry hair caused by ZPT after washing; At the same time, it can improve the wet combing effect of hair and prevent hair winding.shampoo

Betaine can also be used in hair care and hair care products. Its excellent natural moisturizing performance can also give hair luster, increase the water retention performance of hair, and prevent the damage to hair caused by bleaching, hair dyeing, perm and other external factors. At present, because of this performance, betaine has been widely used in personal care products such as facial cleanser, shower gel, shampoo and emulsion system products. Betaine is weakly acidic in aqueous solution (pH of 1% betaine is 5.8 and pH of 10% betaine is 6.2), but the results show that betaine can buffer the pH value of acidic solution. This characteristic of betaine can be used to prepare mild fruit acid skin care products, which can significantly improve the skin irritation and allergy caused by the low pH value of fruit acid.
