Chitosan Lactate

Chitosan lactate is a derivative formed by the ionic bonding of chitosan and lactic acid. It retains the biocompatibility and biodegradability of chitosan while significantly improving water solubility due to the introduction of lactate groups. Its mild acidic adaptability enables broad applications in food, medicine, daily chemicals, agriculture, and other fields. As a leading manufacturer and supplier of chitosan lactate, Tianya Chemical produces high-quality chitosan lactate, tailored to meet the precise demands of these diverse industries.

Characteristics of Chitosan Lactate

Chitosan itself is only soluble in dilute acids, while lactic acid is a natural organic acid. The lactate derivative offers the following advantages:
Good Water Solubility:Lactate groups disrupt intramolecular hydrogen bonds in chitosan, enabling dissolution in neutral or weakly alkaline conditions without reliance on strong acids, broadening application scenarios.
Biosafety:Lactic acid is a natural metabolite in humans. Degradation products are non-toxic, offering excellent biocompatibility and environmental friendliness.
Mild Antibacterial Activity: Chitosan lactate retains chitosan’s antibacterial mechanism. The weak acidity of lactic acid enhances efficacy, particularly against Gram-positive bacteria and fungi.
Film-Forming Ability and Stability: Chitosan lactate forms uniform, transparent films with good flexibility and barrier properties. Resists precipitation due to pH changes during storage, offering superior stability to unmodified chitosan.

Primary Applications of Chitosan Lactate

Food Industry

Food Preservative: Edible films/coatings for meat, produce, and aquatic products:
Coating fresh meat forms breathable, moisturizing barriers against oxygen/microbes, extending shelf life.
Applied to perishable fruits inhibits mold, reducing softening/rotting.
Food Additive: Chitosan lactate is acted as thickener, stabilizer, or gelling agent in dairy, beverages, and baked goods. Water-soluble and odorless, chitosan lactate disperses uniformly to improve texture without altering flavor.
Functional Food Ingredient: Degradation product glucosamine supports joint health and gut flora regulation. Easily absorbed in supplements/special diets due to solubility.

Medicine and Healthcare

Wound Care Materials: Gels, sponges, or dressings provide moist environments with mild antibacterial action to inhibit infection and promote healing—ideal for chronic wounds, avoiding strong acid irritation.
Drug Carrier: Chitosan lactate can enhances dispersion/stability of oral/topical drugs.
Oral Care: Chitosan lactate is added to mouthwash/toothpaste suppresses oral pathogens without irritation, reducing caries/gingivitis risks.

Daily Chemicals

Skincare/Cosmetics: Chitosan lactate can be used as Moisturizer/conditioner in lotions, masks, toners. Hydroxyl/amino groups adsorb water to form hydrating films. Mild acidit maintains barrier function—suitable for sensitive skin.
Hair Care: Chitosan lactate is used in shampoos/conditioners, positive charges adhere to hair surfaces, repairing cuticle damage to reduce split ends/frizz while enhancing softness/shine.

Agriculture

Plant Growth Regulator & Preservative: Water solubility enables easy plant absorption, promoting root growth and disease resistance. Post-harvest fruit coatings form films delaying respiration/water loss.
Feed Additive: Water-soluble prebiotic carrier/gut modulator improves digestibility. Mild antibacterial action inhibits harmful gut bacteria while promoting beneficial bacteria, enhancing animal gut health and feed efficiency.

Advantages of Chitosan Lactate Applications

High Safety: Sourced from natural materials. Non-toxic degradation products suit direct contact with humans, animals, or food.
Broad Applicability: Water solubility overcomes chitosan’s limitations. Processable into solutions, gels, films, microspheres for diverse needs.
Functional Synergy: Chitosan’s antibacterial properties synergize with lactic acid’s weak acidity and nutritional value, enhancing efficacy in preservation, care, and farming applications.
