Description

Chlorhexidine Diacetate is the diacetate salt form of the broad-spectrum antimicrobial agent chlorhexidine. This compound is valued for its potent biocidal activity against a wide range of Gram-positive and Gram-negative bacteria, yeasts, and molds. It is a critical active ingredient for manufacturers in the pharmaceutical, personal care, and veterinary industries, where reliable and effective antiseptic properties are paramount. Its stability and efficacy make it a cornerstone in formulations requiring sustained antimicrobial action.

Application

• Surgical & Healthcare Antiseptics: Key component in preoperative skin scrubs, surgical hand rubs, and healthcare personnel handwashes.
• Pharmaceutical Formulations: Used as a preservative and active ingredient in medicated creams, ointments, and wound dressings.
• Veterinary Medicine: Employed in teat dips, wound sprays, and general disinfectant solutions for animal husbandry.
• Oral Care Products: Found in mouthwashes and toothpastes for controlling plaque and gingivitis.
• Cosmetic & Personal Care: Acts as a preservative in products like creams and lotions to prevent microbial spoilage.
• Surface Disinfectants: Formulated into solutions for disinfecting non-porous surfaces in clinical and institutional settings.
• Industrial Biocide: Used in cooling water systems, fuel tanks, and other processes to control microbial growth.

Quality Control

Our Chlorhexidine Diacetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and cosmetic applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment. We can supply material compliant with various pharmacopoeial monographs (e.g., USP, EP, BP) upon request.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture which can lead to caking or degradation.
