Main Uses

The core function of Didecyldimethylammonium chloride (DDAC) is sterilization and disinfection, while also possessing cleaning capabilities. Specific application scenarios are as follows:

Medical and Health Field

Used for the disinfection of skin and mucous membranes (e.g., pre-operative skin disinfection, wound irrigation), but the concentration is usually low (0.1%-0.5%) to avoid irritation;

Used as a disinfectant for medical instruments, especially suitable for the immersion or wipe disinfection of some heat-sensitive instruments (e.g., endoscopes, rubber products);

Used for the cleaning and disinfection of hospital environments, floors, and countertops, capable of killing vegetative forms of bacteria, fungi, and some viruses.

Daily Use and Personal Care

Added to products such as disinfectants, wet wipes, and hand soaps as a bactericidal ingredient to enhance the antibacterial effect of the products;

Can be used as a preservative in cosmetics (must comply with national standards and control the amount added) to inhibit microbial growth.

Agriculture and Animal Husbandry

Used for environmental disinfection in farms and feed processing plants to kill pathogenic microorganisms in the environment (e.g., bacteria, molds) and prevent livestock and poultry diseases;

Used for seed disinfection or foliar spraying in crop planting to play a role in sterilization and disease prevention (attention must be paid to the safety of the concentration for the crops).

Industrial Field

Used as a water treatment agent for sterilization and algae removal in (industrial) circulating water and swimming pool water, preventing microbial growth that leads to pipeline blockage or water quality deterioration;

Used for antibacterial treatment in the textile and paper industries to impart certain antibacterial properties to products.
