product Introduction:
Triclosan antimicrobials are effective against E. coli, Staphylococcus aureus and Candida albicans, while protecting the beneficial bacteria.Triclosan does not cause resistance in bacteria. Triclosan breaks down quickly in nature, so the chances of developing resistance problems are low. Triclosan is an effective broad-spectrum antibacterial agent, which can kill and inhibit Gram-positive bacteria, Gram-negative bacteria, yeast and viruses.


Product Usage:
Triclosan is widely used in highly effective pharmaceutical soap/sanitary soap, sanitary lotion, deodorant for body odor/foot, sanitizing hand sanitizer, wound disinfection spray, medical device disinfectant, sanitary cleanser/cream, air freshener and refrigerator deodorant, etc., and also used in the finishing of sanitary fabrics and anti-corrosion and treatment of plastics. Higher purity triclochlorine is also widely used in therapeutic toothpastes and mouthwashes for the treatment of dental plonitis, periodontitis and oral ulcers, with a recommended concentration of 0.05% to 0.3%.


Product Characteristics:
1.Fragrant high purity white powder, free from contamination of products and skin.
2.Dissolve in a variety of organic solvents and surfactants.
3.It is highly stable to strong acid, strong base and heat.
4. It has a wide range of killing and inhibiting effects on infectious or pathogenic Gram-positive bacteria, fungi, yeast and viruses (such as A, B, rabies virus, HIV ).
5.No irritation to skin.
6.Antibiotic-resistant bacteria are just as effective as non-antibiotic-resistant bacteria.


Package & Storage:
【Storage】 Sealed dry, dark storage, storage temperature does not exceed 40℃
