Description

Chitosan Oligosaccharide Lactate is a water-soluble derivative of chitosan, produced by enzymatic hydrolysis and subsequent salt formation with lactic acid. This modification enhances its solubility and bioavailability, making it a highly functional biopolymer for advanced applications. It is particularly valued in the agriculture, cosmetics, and nutraceutical industries for its plant growth promotion, moisturizing, and immune-modulating properties.

Application

• Plant Elicitor & Biostimulant: Used in agriculture to stimulate plant defense mechanisms, promote root development, and enhance crop yield and quality.
• Cosmetic Active Ingredient: Functions as a natural moisturizer, film-forming agent, and anti-aging component in skincare and haircare formulations.
• Dietary Supplement & Functional Food: Incorporated into nutraceuticals for its potential prebiotic and immune-supporting benefits.
• Pharmaceutical Excipient: Serves as a carrier material in drug delivery systems due to its biocompatibility and mucoadhesive properties.
• Animal Feed Additive: Used to improve gut health and nutrient absorption in livestock and aquaculture.
• Wound Healing & Medical Materials: Applied in the development of hydrogels, films, and dressings for tissue engineering and wound care.

Quality Control

Our Chitosan Oligosaccharide Lactate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for purity, molecular weight distribution, and heavy metal content. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, degree of deacetylation, and lactate content. We can supply grades suitable for research, cosmetic, agricultural, and nutraceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed after each use to minimize exposure to atmospheric moisture.
