Betaine is an alkaloid with strong hygroscopicity, so anti-caking agent is often used in the production process. Its molecular structure, application effect and natural betaine have no obvious difference, belonging to the chemical synthesis of natural equivalent. Betaine is ubiquitous in plants and animals. It is an intermediate product of animal metabolism and plays an important role in nutrient metabolism.One ingredient found in beet can play a very good role in cleaning, but not harmful to the skin, very safe, was named betaine, modern used for cleaning skin care products safe and effective.
cosmetic grade (cap betaine) capb bulk 30% cocamidopropyl betaine powder
Cocamidopropyl betaine is widely used in the preparation of medium and high-grade shampoos, body washes, hand sanitizers, foam cleansers, etc. and household detergents; it is the main ingredient for preparing mild baby shampoos, baby foam baths, and baby skin care products; in hair care and skin care formulations It is an excellent soft conditioner; it can also be used as detergent, wetting agent, thickener, antistatic agent, etc.

The sample was pre-dried at 105°C to constant weight, 0.4 g of the dried sample was weighed, 50 mL of glacial acetic acid was added, and heated to dissolve. Add 25mL mercuric acetate solution, cool, add 2 drops of crystal violet indicator, titrate with perchloric acid standard solution (0.1mol/L) until the solution turns green, and correct the titration result with blank test.
Colorimetric method: Under the condition of pH=1.0, betaine hydrochloride can form a red precipitate with Ray's salt. After centrifugation, after discarding the supernatant, the precipitate is dissolved in 70% acetone and becomes a pink solution. The maximum absorption peak appears at 525 nm. When the content of betaine hydrochloride is 0.1~12.5mg, it conforms to the Lambert-Beer law.
High performance liquid chromatography: suitable for the determination of betaine content in wolfberry. The betaine component in the sample was extracted with methanol solution (2.5+7.5), purified with mixed cation exchange solid phase extraction column, and then fixed with acetonitrile solution (7.5+2.5), and finally with a UV detector. High-performance liquid chromatograph was used for determination at a wavelength of 205 nm, qualitative determination was performed according to the retention time of chromatographic peaks, and external standard method was used for quantitative determination.
