Product Description

Carboxylenan is a respiratory sputum resolving agent. Athe mechanism of action is to make the sputum mucin disulfide bond cracking, making the sputum viscosity drop, and can increase the sputum Chemicalbook mucus fiber, lubrication the bronchial lining, make low viscosity of saliva mucin secretion increase, high viscosity of algae mucin production, thus make the sputum viscosity is reduced and easy to cough up.Product use

The cystine was dissolved in dilute filtered and added to tin granules to heat up reflux. Dilute the reducing solution with water, remove the remaining tin particles, saturate with hydrogen sulfide, filter, wash the filter residue with a small amount of water, combine the lotion and filtrate, concentrate under reduced pressure, cool and crystallize, and dry L-cysteine hydrochloride
Cystine can be obtained by hydrolysis of α-keratin contained in hair, and then reduced to cysteine by chemical reduction or electrolytic reduction, and then addedto salt.
