Carnosine
L-Carnosine, water-soluble raw material for antioxidant conditioning. Specify application purpose, content specifications and packaging requirements before procurement. Xi'an Wanlv supplies relevant documents and samples.
Overview
What is L-Carnosine?L-Carnosine (INCI: Carnosine, CAS: 305-84-0), chemical name β-alanyl-L-histidine, is an endogenous dipeptide formed by the condensation of β-alanine and L-histidine. It widely exists in human skeletal muscle, brain tissue, skin and other tissues, and has multiple biological activities including capturing active carbonyl substances and scavenging free radicals. It appears as white crystalline powder with excellent water solubility. Prepared via biological fermentation process, its purity reaches ≥99% (HPLC). It is mild and low-irritating, with good compatibility and favorable stability within pH 5.0–8.0 systems. It is widely applied in cosmetics, functional foods, dietary supplements and other fields.
Key Parameters
Applications
Cosmetics
Listed in the Inventory of Existing Cosmetic Ingredients. It features good water solubility and compatibility. Recommended dosage: 0.1%~2.0%. It is suggested to add the material below 50°C in the later production stage to preserve activity. 1. Suitable for anti-aging & brightening serum and stock solution formulations: The raw material can capture active carbonyl substances and scavenge free radicals, suitable for formulation development for mature and dull skin; often compounded with ergothioneine, pro-xylane and various cosmetic peptides. 2. Cream & lotion formulations: Stabilizes collagen and elastin, suitable for formulations targeting early aging and sagging. 3. Eye care (eye cream / eye mask) formulations: Reduces accumulation of oxidative and carbonyl substances in the eye-area system, suitable for formulation development for dull and rough skin. 4. Mask & repair lyophilized powder formulations: Alleviates external irritation and assists formulation protection against photodamage. 5. Other dosage forms: Water-soluble formulations such as toner, spray, base makeup and repair gel.
Functional Foods & Dietary Supplements
1. Sports nutrition formulations: Buffers muscle pH and reduces exercise-induced oxidative stress, for formulation development of protein powder, energy drinks and sports tablets. 2. Oral nutritional supplement formulations: Captures endogenous active carbonyl substances and reduces oxidative stress, for formulation development of nutritional capsules and tablets. 3. Meat product preservation: Inhibits lipid oxidation and stabilizes meat color, used as a color-protecting antioxidant auxiliary agent.
Research & Other Applications
1. Biochemical research reagent: Culture medium protectant to reduce cellular oxidative damage for in-vitro cell experiments. 2. Pharmaceutical intermediate: Applied in R&D of related preparations.
