Widely used in medical antisepsis, livestock breeding, food plant sanitation, aquaculture and daily disinfection products. Stable batch indicators, complete export documents and customizable packaging.


Povidone Iodine, abbreviated PVPI / PVP-I, CAS 25655-41-8, is a stable loose complex formed by polyvinylpyrrolidone (Povidone) and elemental iodine. Our Sinobio adopts advanced complex synthesis and purification technology to produce free-flowing reddish-brown amorphous powder, complying with USP standard specifications.
Different from traditional iodine tincture, PVPI effectively solves the defects of free iodine such as strong irritation, volatile loss and poor water solubility. Povidone acts as carrier and solubilizer; once contacting microbial surface, it slowly releases active iodine to destroy microbial protein structure and achieve sterilization. It features mild performance, low toxicity, easy water dissolution and long-lasting bactericidal activity. We supply standard industrial sanitation grade, veterinary grade and pharmaceutical raw material grade to satisfy diversified downstream formulation demands for disinfectant manufacturers, farms and medical material enterprises.
*Preoperative skin disinfection, wound antisepsis, mucosal disinfection; raw material for medical disinfectant, wound care ointment and surgical scrubs.
*Disinfection for medical equipment, ward environment and hospital surface sanitation.
*Livestock & poultry farm environment, breeding equipment disinfection; cow teat disinfection, prevention of livestock bacterial diseases.
*Aquaculture water body disinfection, inhibits aquatic pathogenic bacteria and fungi, improves water environment.
Sanitizer for food production equipment, pipeline, workshop floor and food contact surfaces; controls cross-contamination of microorganisms.
Core raw material for household disinfectant spray, sanitizer liquid, feminine care cleaning products and pet disinfection supplies.
Water treatment microbial inhibitor, laboratory microbiology testing reagent, textile antibacterial finishing auxiliary.
PVPI is PVP-iodine complex with low free iodine, mild and low irritation; iodine tincture contains high free iodine, easy to cause skin irritation and corrosion.
Not allowed. Reducing substances will consume active iodine and completely lose disinfection efficacy.
UN3077 Class 9 environmentally hazardous substance. We provide complete MSDS and shipping documents for customs clearance.
Sample order 1–5kg; bulk order minimum 25kg. Contact us for latest factory quotation.
