Claim 0:
1. A preparation method of a sulfur-containing product, wherein the preparation method comprises the following steps:
(1) providing a nano-sulfur containing composition comprising nano-sulfur, solvent(s) and anti-agglomerating agent(s) used for preventing or retarding agglomeration of the nano-sulfur by the following method (a) or (b), the nano-sulfur and anti-agglomerating agent(s) are dispersed in the solvent(s):
(a) reacting thiosulfate(s) or polysulfide(s) with acid(s) in the presence of anti-agglomerating agent(s) in solvent(s) to obtain a nano-sulfur containing composition;
(b) preparing a nano-sulfur containing composition by micro-emulsion method using thiosulfate(s) or polysulfide(s), and acid(s) as reaction raw materials and in the presence of anti-agglomerating agent(s) and solvent(s) to obtain a nano-sulfur containing composition;

(2) mixing the nano-sulfur containing composition prepared by method (a) or method (b) directly without additional operations of removing anti-agglomerating agent(s) and/or byproducts with other components of a sulfur-containing product;, the sulfur-containing product is a toiletry for use on the surface of the skin on humans or animals, a drug for treating skin disorders, a drug for treating tumors, a drug for treating hair disorders, an agricultural chemical, a plant preservative for vegetable and fruits, an additive for animal feed, an additive for mold-prevention in paint, a mold prevention agent for textiles or textile mite-killing agents.
