|
Sodium
Pyrithione inhibits the growth of fungi, yeast,
mold and bacteria. It is used in formulating
anti-microbial
property in paint, sealants,
shampoo,
adhesive and aerosol. Amine N-oxides are active components in body care products such as shampoo,
bubble bath, and hand-soap formulations as they are cationic and can act as a mild conditioner
in acidic media.
In neutral or weak basic media, they are featured as excellent stabilizer
and viscosity building provider.

GENERAL
DESCRIPTION OF PYRIDINETHIONE
|
|
Pyridinethione inhibits the growth of fungi, yeast, mold and bacteria. Sodium and zinc salt of
pyrithione N-oxide are widely used in cosmetics and shampoo. In acidic media, amine N-oxides are cationic and can act as a mild conditioner.They
are used in body care products. Pyridinethione derivatives, belong to a class of
cyclic sulfur organo products containing sulfur atom (S) and often oxygen (O),
nitrogen (N), hydrogen (H), as well as other elements, can find application for
making biologically active agents such as antiviral, antibacterial, antifungal
, antituberculous, antbody and antifungal agents. Pyrimidine is a
heterocyclic compound containing nitrogen atoms at positions 1 and 3 in
six-membered ring structure molecule. The three major pyrimidines in living systems are cytosine, thymine, and uracil.
Pyrimidine and its derivatives are biologically important components of nucleic
acids (DNA, RNA) and coenzymes. They can be the parent compound of many drugs,
including the barbiturates. |
