Properties:
(1)Bactericidal capacity:
TCC is a high-duty, wide-spectrum bacteriostastic agent. It has fine compatiblity with skin or fiber, and high effects on inhabiting and killing gram-positive, gram-negative bacteria, funguns and virus. It has long effect with small dosage. It has been widely used as an active antibacterial composition in series of cosmetics, mouth-tending agents, cleaning agents, medical disinfectants and medical products through several decades.
(2) Stability
Compared with traditional chlorine and oxygen system bactericide, TCC has the outstanding merits, that is, it has fine stability and compatibleness.
(3) Solution
It can not be dissolved by water with great effort, but by alcohol dilution and non-ionic surfactants.
(4) Security
No poison. No irritation to eyes and skin according to American FDA Standard.

Product Application:
1. Appliance field:
(1) Washing powder with the dilution of TCC can kill pathogenic bacteria and get rid of bad odors because of bacteria's multiply.
(2) If TCC is added in deodorant soap, it can be used by doctors, patients, and foods producers for washing hands. As a result, it can reduce cross-infection, body odors, perspiration odors and protest sexual diseases.
(3) If TCC is added in rinsing water and toothpastes, it can also eliminate gum infection, halitosis, and gym, with fine mouth sensation.
(4) If it is added in foot-tending agent, it can delete foot odor and prevent foot-rotten.
(5) If it is added in face-emulsion and cleansers, it can kill bad bacteria and finish both processes at the same time for cleaning skin and prevention acne.
(6) If it is added in prickly heat powder, it can prevent infants' skin from prickly heat and skin disease.
(7) If it is added in shampoo, it can prevent head scraping and furfuration. In addition to, TCC can be used in antibacterial towel, cleaning tissues, wound paste and so on. TCC has good adheres ion with fiber. It can be added in antibacterial pre-odor fabricates. Crylic acid colophony processed by TCC will get bactericide and antibacterial crylic acid system fiber. This kind of fiber will have a fine anti-bacterial and anti-fungus capacity after several times' washing with high security. Polyacrylonitrile fiber sprayed and dipped by TCC will have strong anti-bacterial and anti-odor capacity.
2. Using quantum: 0.2-0.5% (GB7916-87)
3. Dissolved by: non-ionic surfactants such as 6501, AEO9, AEO7, Polyglycol 300, Polyglycol 400, Polyglycol 600 and TX-10

The Appliance Method of TCC
1. Solubility date of TCC at 25C in normal dissolvent

2. Guide of formulation
(1)added in the form of powder
TCC powder can be well dispersed in the product, before pigment, dye, perfume stuff and other material are incorporated homogeneously in soap flake, the soap material should be stabilized. Those affinity hydrophilic materials should be added at first, then are hydrophobic materials, the normal adding order is as follow: soup flake, sodium silicate, antioxidant pigment solution, TIO2, optical brighter, TCC and perfume stuff, the perfume stuff must be added at taste.
(2) Added in the form of liquid
TCC should be dissolved in suitable liquid, then add the solution to the formulation; the solubility of TCC in some non-ionic detergent is about 15-20%. Used in soap, TCC can be incorporated homogeneously in its raw materials, Used in washing powder, TCC should be dissolved in AEO7 or AEO9 firstly then mix it with other materials of washing powder.

NOTE
Because TCC can be decomposed at high temperature, the temperature of the product must under 100C, 50C at best.
