Description

Chlorhexidine acetate (CAS 56-95-1 ), also known as chlorhexidine diacetate and sold under the trade name Hibitane diacetate, is a broad-spectrum antimicrobial salt used across pharmaceutical, personal care, and healthcare manufacturing. It delivers reliable bactericidal and fungicidal activity at low concentrations, making it a preferred active ingredient where microbial control is a critical formulation requirement for industrial and medical applications. In pharmaceutical manufacturing, it is incorporated into topical antiseptic solutions, wound care products, and surgical scrubs where regulatory-grade antimicrobial performance is required for safety and efficacy. Personal care formulators use it as a preservative and active biocide in mouthwashes, skin cleansers, and intimate hygiene products. Water treatment applications include its use as a biocide for controlling microbial growth. It also functions as a preservative in ophthalmic preparations and contact lens solutions, where low irritation potential at effective concentrations is a key formulation consideration for manufacturers. Chlorhexidine acetate is supplied as a white to off-white crystalline powder. It is available in pharmaceutical-grade specifications including BP and Ph. Eur. , which are the standard grades demanded. These quality standards ensure the material is suitable for healthcare and regulated personal care markets. Technical-grade material is also available for industrial biocide applications and process water treatment. Contact us for supply of Chlorhexidine acetate Request Quote
