Introduction to the Product
The product is the acetylated derivative of L-Carnosine to overcome the fast enzymatic breakdown in biological systems. This white crystalline powder is molecularly stable across the corneal barrier and acts as an intelligent prodrug that transforms to active L-carnosine in ocular tissues. The acetyl modification offers longer release qualities and better tissue penetration than regular carnosine formulations. Our pharmaceutical-grade substance is highly water soluble and stable under regulated storage circumstances and is suitable for ophthalmic solutions and advanced eye care formulations for the treatment of oxidative stress.

N Acetyl Carnosine Powder Advantages
Improved bioavailability: An N-acetyl protective group against carnosinase enzymes gives the dipeptide 8-10 times higher serum stability than unmodified carnosine and ensures active molecules reach target tissues.
Excellent corneal penetration: Lipophilic acetyl modification allows passive diffusion via ocular membranes to reach therapeutic quantities in the aqueous humour within 30 min of topical treatment.
A time-release prodrug that converts to L-carnosine in ocular tissues provides long-term ROS scavenging and lipid peroxidation prevention.
Clinical-Grade Purity: Our product's 99% purity reduces contaminants, ensuring dose accuracy and predictable therapeutic effects in clinical and commercial applications.
Regulatory Compliance: manufactured under cGMP procedures, full paperwork assistance to assist your regulatory filings in worldwide markets including FDA and EFSA countries.

Application N Acetyl Carnosine Powder
Ophthalmic Solutions: Active ingredient in anti-cataract eye drops. Formulated at 0.3-1.0% doses to relieve age-related lens opacity by deglycating crystallin protein and reversing oxidative damage.
Nutraceutical Supplements: Incorporated into capsules and tablets at dosages of 50-200mg daily for systemic antioxidant support, notably for age-related degenerative disorders of the eye.
Anti-Aging Formulations: Utilised in speciality serums and topical formulations at 2-5% levels, capitalising on its capacity to suppress protein glycation and cross-linking in the skin.
Sports Nutrition Products: Included in performance supplements to buffer lactic acid build-up and decrease exercise-induced oxidative stress, to help with muscle repair and endurance ability.
Veterinary Ophthalmology: Used in pet care products with N Acetyl Carnosine Powder for canine and feline cataracts, offering non-surgical intervention alternatives to veterinary experts throughout the globe.


Manufacturing Process
Step 1 – Raw Material Selection: Certified suppliers of high quality L-Carnosine are identity tested using NMR spectroscopy to confirm the right molecular arrangement before being processed into the acetylated form.
Step 2 - Acetylation reaction: Chemical acetylation is performed under nitrogen atmosphere at regulated temperature and pH conditions. This controlled reaction shields the N-terminal and leads to the formation of protected dipeptide with >98% conversion efficiency.
Step 3 - Purification Treatment: Multi-stage crystallisation and recrystallisation from aqueous-ethanol systems remove unreacted precursors and side products to provide pharmaceutical-grade purity of >99%.
Step 4 - Drying and Milling: Vacuum drying at regulated temperatures below 40°C protects molecular integrity, followed by jet milling to provide homogeneous 80-120 mesh particle distribution for optimum solubility.
Step 5 – Quality Testing: Each batch undergoes stringent testing for HPLC purity, moisture content, heavy metals and microbiological parameters before to release to guarantee compliance with international pharmaceutical standards.
Step 6 - Sterile Packaging: Double-layer PE bags with nitrogen flushing to avoid oxidation, packed in fibre drums in 100,000 level clean rooms, and stability maintained for 24-month shelf life.
