DETAILED DESCRIPTION OF THE INVENTION The present invention provides stabilized 2-zinc pyridinethiol-1-
The present invention relates to a method for producing an aqueous suspension of oxide (hereinafter abbreviated as Z-Pt).

Z-Pt is known as an anti-dandruff cosmetic because it has strong antibacterial properties. However, since Z-pt is insoluble in water, in order to fully demonstrate its effects, it must be made into a slightly intoxicating powder to improve contact with the skin, and must be made into a powder that can be quickly removed to prevent side effects. It is usually used in shampoo form as an aqueous suspension containing a surfactant. However, although Z-Pt is a relatively stable white crystalline compound in a dry state, especially when shielded from light, it has the property of decomposing in the presence of trace amounts of moisture or light to form disulfide.

This product exhibits a color ranging from black to charcoal-purple, and may sometimes emit a peculiar tinge. Furthermore, Z-Pt has the property of accelerating its decomposition in the presence of a trace amount of iron ions. These properties of Z-Pt not only eliminate the product value of the shampoo as an aqueous suspension, but also deprive the shampoo of its own ability to cleanse the hair.

It has been discovered that it is possible to obtain an aqueous suspension in which t is stabilized, and the present invention has been achieved.
