Source of Carboxymethyl Chitosan

Carboxymethyl chitosan is a chemically modified derivative of chitosan, which is primarily derived from chitin. Chitin is a natural biopolymer that can be found in the shells of crustaceans like shrimp and crab, as well as in the cell walls of fungi. Chitosan is obtained by deacetylating chitin through a chemical process.

Carboxymethyl chitosan is produced by further modifying chitosan through the carboxymethylation process, which involves adding carboxymethyl groups to the chitosan molecule. This modification can be achieved by reacting chitosan with chloroacetic acid, sodium hydroxide, and other reagents. The resulting carboxymethyl chitosan is a water-soluble polymer with various applications in industries like pharmaceuticals, cosmetics, and food processing, among others.

Carboxymethyl Chitosan is a derivative of chitosan produced by carboxymethylation of chitosan. It has a series of physical and chemical properties, which depend on the chemical structure and preparation method of carboxymethyl chitosan.

Appearance: Carboxymethyl Chitosan is usually a white to light yellow powder and may also be supplied in other forms such as granules or granules.

Solubility: Carboxymethyl Chitosan has good solubility in water because carboxymethylation increases its water solubility. This makes its application in cosmetics and pharmaceuticals more convenient.

Molecular Weight: Molecular weight can vary depending on the method of preparation, typically ranging from a few thousand to hundreds of thousands of daltons.

pH stability: Carboxymethyl Chitosan is generally more stable under neutral to slightly acidic conditions. In acidic environments, it may undergo hydrolysis.

Thermal Stability: Carboxymethyl Chitosan is relatively stable at high temperatures, but can decompose at extremely high temperatures.

Gelling properties: Carboxymethyl Chitosan can be used as a gelling agent with thickening properties and can increase the viscosity of cosmetics and pharmaceuticals.

Hydrophilicity: Carboxymethyl chitosan exhibits strong hydrophilicity, allowing it to absorb and retain moisture.

Biocompatibility: Carboxymethyl Chitosan is generally considered to have good biocompatibility and can be used in skin care products and drug delivery systems.

The preparation process of Carboxymethyl Chitosan involves carboxymethylation of chitosan, a chemical modification process that enhances chitosan's water solubility and changes its properties. Here is a common preparation process:

Preparation steps:

Deacetylation of chitosan: Chitosan first needs to be deacetylated to remove part of the acetyl group. This can be achieved by reacting chitosan with sodium hydroxide or sodium bicarbonate under mild conditions, followed by washing with alcohol.

Carboxymethylation reaction: deacetylated chitosan reacts with chloroacetic acid or formic acid to introduce carboxymethyl groups on the chitosan molecule. This step is usually performed under alkaline conditions, and the pH can be adjusted by adding sodium hydroxide or sodium bicarbonate. The reaction is usually carried out at room temperature.

Neutralization and washing: After completing the carboxymethylation reaction, wash the product with ethanol or methanol to remove unreacted reagents and by-products. Additionally, the product needs to be neutralized to ensure it is in a neutral or appropriate pH range.

Drying: Finally, carboxymethyl chitosan can be prepared into powder or other desired form through a drying process.

The effects of Carboxymethyl Chitosan

Carboxymethyl Chitosan has many applications in the cosmetics industry, mainly due to its versatility and biocompatibility. Applications of Carboxymethyl Chitosan in cosmetics:

1.Moisturizer: Carboxymethyl Chitosan can absorb and retain moisture, so it can be used as a moisturizer. It helps maintain skin's moisture balance, reducing dryness and dehydration, leaving skin feeling soft and smooth.

2.Sunscreen: Due to its antioxidant properties, Carboxymethyl Chitosan can also be used in sunscreen products to help protect the skin from harmful UV radiation.

3.Anti-inflammation and repair: Carboxymethyl Chitosan is believed to have anti-inflammatory properties, which can reduce skin inflammation and sensitivity and help repair damaged skin.

4.Reduces uneven skin tone: Carboxymethyl Chitosan can be used to lighten uneven skin tone, such as spots and blemishes. It helps lighten dark spots on the skin and brightens the complexion.

5.Gelling agent: In cosmetics, Carboxymethyl Chitosan can also be used as a gelling agent to help increase the viscosity and stability of the product.

6.Hair care products: Carboxymethyl Chitosan can also be used in hair care products to help increase hair shine, reduce static electricity, and increase hair softness.
