Known Appli­ca­tion

Car­boxymethyl chi­tosan CAS 83512-85-0 exhibits excel­lent water sol­u­bil­i­ty, supe­ri­or film-for­m­ing prop­er­ties, and strong heavy met­al chela­tion capa­bil­i­ties.
Car­boxymethyl chi­tosan has been uti­lized as a drug release agent, a plant growth enhancer, and a heavy met­al chelat­ing agent. Wide­ly applied in the cos­met­ics indus­try, it helps reduce skin oxida­tive dam­age, delay aging, and retain skin moisture.
