Description

Povidone Iodine is a stable chemical complex of polyvinylpyrrolidone (povidone) and elemental iodine, widely recognized for its potent and broad-spectrum antiseptic properties. This complex provides sustained release of iodine, offering effective microbial control while minimizing irritation compared to tincture of iodine. It is an essential active ingredient for manufacturers in the pharmaceutical, medical device, and personal care industries, where reliable and safe disinfection is paramount. Povidone Iodine CAS NO 74500-22-4 is a cornerstone material for formulating advanced antiseptic solutions, surgical scrubs, and wound care products.

Application

• Pharmaceutical Antiseptics: Primary active ingredient in topical antiseptic solutions, ointments, and sprays for pre- and post-operative skin disinfection.
• Surgical Scrubs & Hand Washes: Key component in healthcare personnel hand rubs and surgical scrubs for persistent antimicrobial action.
• Wound Care Products: Used in gels, creams, and impregnated dressings for managing burns, ulcers, and minor cuts to prevent infection.
• Medical Device Disinfection: Employed in solutions for disinfecting medical instruments and hard surfaces in clinical settings.
• Veterinary Medicine: Formulated into teat dips, wound sprays, and general disinfectants for animal healthcare.
• Personal Care & Cosmetics: Incorporated into soaps, mouthwashes, and feminine hygiene products for its sanitizing benefits.
• Food Industry Sanitizers: Used in approved formulations for sanitizing food processing equipment and surfaces.

Quality Control

Our Povidone Iodine is manufactured under strict quality management systems, with grades available to meet USP, EP, BP, and JP pharmacopoeial standards. Every batch undergoes comprehensive analytical testing, including assay for available iodine, identification, loss on drying, and heavy metals limits, to ensure consistent purity and efficacy. Certificates of Analysis (COA) documenting full compliance with agreed specifications are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and assay.
