CS264559B1 - A method for producing bioactive sulfur - Google Patents

Abstract

The process for producing bioactive sulfur is that the sulfur is melted in a liquid medium containing at least two hydroxyl groups, after the sulfur has melted, the mixture is again cooled to room temperature, with a disintegrant acting on the mixture for the duration of melting and / or solidification of the sulfur, for example ultrasound. This sulfur is suitable for medical and cosmetic purposes.

Description

The invention relates to a process for producing sulfur.

At present, sulfur, which is variously modified to obtain the finest crystals or colloids, is used in agriculture, cosmetics and medicine to be biologically effective. Sulfur used in medicine and cosmetics sometimes irritates the skin and sometimes is ineffective.

These drawbacks are overcome by the process for producing bioactive sulfur according to the invention. The essence of the invention is that the sulfur melts in the liquid medium of substances containing at least two hydroxyl groups. During the melting and / or solidification of the sulfur, the mixture is treated with a disintegrant, for example by ultrasound. After melting the sulfur, the mixture was cooled again to room temperature. The process according to the invention removes gases sorbed on the sulfur surface and allows a spherical shape to be achieved. Most likely, besides sorbed air, it is sulfur dioxide and sulfur thanks to the sulfur surface. While sorbed air is harmless to health, but can reduce the effectiveness of sulfur, sulfur dioxide and hydrogen sulfide already have an irritant effect and can cause allergies. These substances are removed by the process according to the invention.

According to the invention, the treated sulfur has a spherical shape, which is obtained by vibrating the molten sulfur in an auxiliary liquid phase, for example glycerin, with a disintegrator, for example by ultrasound. Both temperature above the melting point of sulfur and ultrasonic treatment will remove undesirable gases on the sulfur surface. Molecules from the liquid medium in which the sulfur is melted are sorbed onto the vacant spots on the sulfur surface. for medical purposes, liquids having two or more hydroxyl groups, divalent alcohols such as glycols or their polymers, trivalent alcohols, sugars, etc., are used. cooling, sulfur is present in the form of spheres. The size of the beads is a function of the temperature, the auxiliary liquid phase used, the intensity and frequency of the disintegrator, and the cooling. The sulfur produced according to the invention is in fact sulfur perfectly wetted by a liquid or solid phase with a large surface area.

The bioactive sulfur prepared according to the invention is suitable for use in medicine and cosmetics.

Example 1

The sulfur powder is boiled with glycerine to a temperature above the melting point of the sulfur until substantial deaeration, degassing and melting of the sulfur is achieved. Ultrasonication removes the last gas residue and at the same time disintegrates the liquid sulfur, which in the form of beads is dispersed in glycerin. After cooling, which takes place under the constant action of the disintegrator, glycerin contains bead sulfur, which has remained unchanged in this environment for two years and has no significant odor.

Example 2

To the molten glucose was added sulfur powder. Ultrasound was introduced into the melt, followed by cooling of the sulfur, and then the melt was either dissolved in glycerins or degassed water. Similarly, a solution of glucose in water was tested instead of molten glucose. Various carbohydrates with similar results to glucose were used as the liquid medium for sulfur. For veterinary purposes, polyethylene glycol, sugar derivatives, etc. may be used instead of carbohydrate solution or melts, with very good results.

The biologically active sulfur thus prepared has a spherical shape for more than two years. Added in a small amount to the shampoo subjectively reduced hair loss, itching of the head and reportedly reduced the number of gray hair discoloration after a month of use. The preparation is also well tolerated by allergic patients and has antifungal effect.

Bioactive Sulfur v. Glycerine Prepared in this way Removes the itching of the skin.
