Carboxymethyl chitosan is a derivative of chitosan after molecular modification and is hailed as the "sixth essential element of life". It is the only natural molecule material with a positive charge in nature, effectively adsorbing heavy metals, skin hormones, and toxins, and is thus called the "skincare scavenger".
In the medical field, carboxymethyl chitosan has demonstrated multiple values. Professor Zhou Jinping's team from Wuhan University has developed an injectable hydrogel dressing based on carboxymethyl chitosan.
This hydrogel utilizes metal ion cross-linking technology and can quickly form within 10 seconds. It features self-healing, injectability, and temperature responsiveness, significantly promoting skin tissue regeneration and accelerating wound healing rates.
In the skincare field, carboxymethyl chitosan is bringing revolutionary changes. The ZhiYuanbrand has incorporated it as the core ingredient in all its products, leveraging its abilities to promote micro-wound healing and repair, form a protective film, moisturize and hydrate, adsorb heavy metals, and soothe and relieve pain.
After molecular modification, carboxymethyl chitosan has a smaller molecular weight, faster absorption and dissolution speed, more significant usage effects, and higher safety. Even those with problem skin can use it with confidence.
Research and development of carboxymethyl chitosan continue to make breakthroughs. The team led by Liu Yang from South China University of Technology has developed a multifunctional hydrogel based on carboxymethyl chitosan modified with phenylboronic acid, which has good injectability, self-healing properties, and antibacterial properties.
With the deepening of research and development, the application fields of carboxymethyl chitosan are constantly expanding. Research teams at home and abroad are exploring its potential in drug controlled-release systems, tissue engineering materials, and other fields.
The transformation of carboxymethyl chitosan from marine waste to high-value products not only enhances the value of resource utilization but also provides innovative solutions for the medical and skincare industries, demonstrating the huge potential of the blue economy.
