Dextran CAS# 9004-54-0
Dextran is a glucose polymer mainly composed of α-1,6-glucopyranosidic linkages. It is produced from sucrose by Leuconostoc mesenteroides and related microorganisms, and can also be generated from dextrins by other bacterial species.
Dextran is commonly used in bead form for applications in bioreactors, as well as in certain size-exclusion chromatography matrices and osmotic stress studies involving biological molecules. In addition, it can act as a stabilizing coating for metal nanoparticles, helping to protect them from oxidation.
Dextrans are long-chain glucose polysaccharides with a range of relative molecular weights. For example, Dextran 70 (with a relative molecular mass of approximately 70,000) remains in the intravascular space, where it contributes to the colloid oncotic pressure of plasma, similar to albumin. Unlike albumin, however, large doses of Dextran 70 can inhibit platelet aggregation and promote fibrinolysis.

Product Usage
Kojic acid (CAS# 501-30-4) has a wide range of applications across several industries. In the cosmetics industry, it is commonly used in whitening creams and other skincare products because it can inhibit tyrosinase activity and provide antioxidant effects, helping to reduce pigmentation and freckles. It is also incorporated into sunscreen formulations to enhance sun protection.
In the food industry, its antibacterial and antioxidant properties help preserve the freshness of fruits, vegetables, and meat, while also maintaining the color of processed foods such as fruit juices.
In the pharmaceutical field, kojic acid is used to help treat pigmented skin conditions such as melasma, and it may also serve as an antibacterial and anti-inflammatory ingredient in topical medications.
Additionally, kojic acid can be applied in agriculture as a plant growth regulator, and in industrial production as an antioxidant and metal ion chelating agent.
