20220081294
The following relates to a nano-sulfur containing composition and application thereof.
Sulfur is a very active non-metallic element that is widely used in the manufacture of sulfuric acid, agricultural chemicals, chemical fibers, rubber, dyes, paper-making, pharmaceuticals, explosives, matches, etc. Sulfur plays an important role in our daily lives, such as sulfuric acid for disinfection, sulfur ointment for treating skin diseases, etc. Sulfur in nature is also closely related to our health. For example, sulfur hot spring is called “soup for skin”, which has the effect of softening the stratum corneum of skin and efficacy of antipruritic, detoxification and detoxification. Sulfur hot spring is especially useful to improvement of arthritis, dermatitis and neuralgia, mainly due to the disinfection and sterilization effects of sulfur. Supplying polysulfide-rich food such as garlic, onions, leeks, cabbages, broccoli, cauliflower, etc. to human is particularly beneficial to health, mainly because some of sulfur containing compounds work.
Although sulfur is widely used, its specific application is greatly limited. For example, commercially available sulfur preparations such as sulfur ointments or sulfur creams, although indicated in their instructions that it can treat many skin diseases, the effects are not good in practical clinical applications, and are almost obsolete in the market. The main reasons are as follows: 1) Sulfur is insoluble in water, so the sulfur particles in the paste are large (usually several tens of micrometers) and are difficult to be absorbed by the skin, low in antibacterial activity and bioavailability, and not good in medical effect; 2) The sulfur ointment or cream, with more amount of sulfur used, is irritating. After using, many patients suffer allergic, peeling, and dry skin, and possibly dermatitis after long-term application; 3) The proportion of sulfur used is relatively large, generally about 5%, and some reach 10%, which has a strong sulfur odor.
The raw materials used in the preparation of the commercially available sulfur preparations are all micron-sized particles, and it has been proposed to use nano-sulfur instead of micro-sulfur to prepare a sulfur containing preparation. For example, CN105708770A discloses an acne toner comprising a mixture of a carrier and an active ingredient in a percentage by weight, including: carrier: propylene glycol 3-15%, 1,3-butanediol 6-10%, sorbitol 5-8%, deionized water 64.9-85.2%; functional components: nano-sulfur 0.5-1.3%; other functional ingredients 0.3-0.8%. However, the description of the nano-sulfur in this patent is limited to the nanometer sulfur particle size of 50 nm and it can be obtained by processing elemental sulfur using nanotechnology (see paragraphs [0006] and [0031] of the specification), i.e., the patent does not specifically describe how to obtain nano-sulfur powder with a particle size of about 50 nm and the characterization data of the nano-sulfur powder. According to the existing documentary records (for example, CN1453205A and CN104944381), preparation processes of nano-sulfur powder are usually very complicated, resulting in high cost; in addition, although the particle size of the nano-sulfur powder as a raw material is relatively small, once added into the acne toner system or other application system, the nano-sulfur powder will be significantly agglomerated, forming a larger particle size of sulfur particles, so that it is difficult to effectively act on bacterium or germs on the surface of or in the pores of the skin. Similarly, it is difficult to effectively sterilize other substrates with bacteria or bacteria.
Throughout the sulfur containing products in the conventional art, all sulfur containing products are obtained by firstly obtaining solid sulfur powder with high-purity, and then dispersing the sulfur powder into other components of the sulfur containing products, and mixing. The sulfur containing product obtained by such method, its sulfur is easy to agglomerate, and has low activity, poor effect and limited application.

The effect of additional factors on the maintenance of the nanostate of nano-sulfur is reduced or even avoided.
Due to the adoption of the technical solutions above, the present disclosure has following advantages compared with the conventional art:
Embodiments of the invention overcome the defects that the nano-sulfur is easy to agglomerate during the preparation or use of the traditional nano-sulfur, and realizes that the nano-sulfur can keep nano-state for a long time. After the nano-sulfur containing composition has been kept for a long time by the inventor (more than half a year at present), the nano-sulfur in the prepared composition was still maintained in the nano-state and uniformly dispersed in the dispersion medium, which basically eliminated agglomeration. The nano-sulfur containing composition of the present disclosure can be added to any product requiring sulfur, and can obtain a better effect with a lower addition amount.
The sulfur containing product of embodiments of the invention, wherein the nano-sulfur keeps a very good dispersion and a small particle size, the sulfur activity can be fully exerted, and the application effect is significantly better. At the same time, due to that the activity of sulfur can be fully developed, the amount of sulfur can be greatly reduced, which can reduce or avoid the negative problems caused by the big amount of sulfur. In addition, the sulfur containing product of embodiments of the invention has low cost. Therefore, the sulfur containing product of embodiments of the invention is easy to be popularized.
Some of the embodiments will be described in detail, with references to the following Figures, wherein like designations denote like members, wherein:
wherein, the nano-sulfur still maintains the initial state and is still uniformly dispersed in the dispersion medium.
The conventional preparation method of the sulfur containing product is to obtain a high-purity solid sulfur powder firstly, and then disperse the sulfur powder into other components of the sulfur containing product, and mix them to obtain a sulfur containing product. The sulfur products obtained by the traditional method are easy to agglomerate even if the particle size of the raw material sulfur powder is very small and various auxiliary dispersion means are used, which will affect the use effect.
Through research, the inventor accidentally found that the nano-sulfur formed is not easy to agglomerate when an assistant (or anti agglomerate) which can prevent or delay agglomeration is added before the formation of nano-sulfur and the assistant is still retained after the formation of nano-sulfur. Furthermore, when the composition of the nano-sulfur and the auxiliary agent is used to prepare sulfur containing products, the nano-sulfur keeps a very good dispersion performance and a small particle size, so the activity of sulfur in the prepared sulfur containing products can be brought into full play, and the application effect is significantly better. Furthermore, as the activity of sulfur can be brought into full play, the amount of sulfur can be greatly reduced, which can reduce or avoid the negative problems caused by the big amount of sulfur
Embodiments of the invention overcome the traditional prejudice that the high-purity sulfur powder should be prepared first and then used (it is generally believed that there may be a small amount of impurities in the raw material, but the by-products are not allowed, otherwise the quality is not good, for example, the purity is emphasized in many literatures on nano-sulfur). In addition to nano-sulfur, the nano-sulfur containing composition of some embodiments of the present disclosure contains auxiliary agent (anti-agglomerating agent) and residual thiosulfate, polysulfide and acid, etc. These components are not only harmless, but also beneficial in most cases. The following are illustrating examples:
Other by-products and the like are not illustrated one by one, but they are all beneficial, at least harmless.
Specifically, according to different applications of sulfur containing products, appropriate anti-agglomerating agent, thiosulfate or polysulfide and acid for preparation can be selected to obtain nano-sulfur and beneficial additives at the same time, which can be described as killing two birds with one stone. More importantly, the complex and high-cost purification process is avoided, greatly reduce the cost of nano-sulfur production.

The above Examples 22-44 merely exemplarily provide some sulfur containing products prepared by using the nano-sulfur containing composition prepared according to the concept of the present disclosure and preparation method thereof. And in the present disclosure, it is emphatically described that the nano-sulfur containing composition of the present disclosure is added into sulfur containing products such as pastes, lotions and creams, which specifically is to adding the nano-sulfur containing composition of the present disclosure into the existing or new formulations of the products and then stirring evenly, while it does not specifically define the order of the preparations of the nano-sulfur containing composition of the present disclosure and the basic toiletries or pharmaceutical compositions, there are no time priorities between the two steps.
The inventor of the present disclosure was diagnosed with seborrheic dermatitis due to repeated redness, peeling and pain of the facial skin. After daubing the ointment prescribed by the doctor, the dermatitis was cured after a few days, but if the ointment was not used, it would recur about one or two weeks later. It has happened so many times and then went to see the doctor over and over again, but it wasn't cured.
At the same time, all the ointments prescribed by doctors were ointments containing hormones. The inventor was worried about the side effects of hormones. After the inventor checked the data, he found that sulfur ointments can treat seborrheic dermatitis, so he bought back sulfur ointments or creams. However, after using them, he found that these sulfur ointments had no effect. According to the inventor's research, the reason for this inefficacy was that the particle size of sulfur was too large to be absorbed by the skin to make use of its antifungal property. Even though there is about 5% content in the existing ointment, it has little effect, and it also makes the ointment have strong irritant smell, which is not in line with the actual needs.
Later, the inventor used his self-made nano-sulfur cream, in which the sulfur content could be only a few thousandths, but it worked very well. Moreover, the inventor used it for more than one year, and there was no side effect such as dry skin peeling.
In addition, for the same reason, the inventor had a large amount of dandruff, and the ordinary shampoo had no effect, such as Zinc pyrithione (ZPT)-containing, or coal tar-containing shampoo and other shampoo. The inventor also went to the doctor for help. The doctor (Canada) recommended ketoconazole shampoo. There was a similar product “Kangwang” in China. But after two or three years of using ketoconazole, it didn't work either. Later, shampoo containing selenium sulfide (not available in China before, but also available now) was used, which had some effect, but selenium sulfide was a highly toxic or highly toxic chemical substance, which should not be used more.
Now the inventor uses the self-made nano-sulfur shampoo (obtained by adding the nano-sulfur containing composition of the present disclosure into the existing shampoo), which has excellent effect, which has been used for more than one year, and has not found any adverse side effects, and basically avoids the generation of lots of dandruff.
The above embodiments are only for explaining the technical concept and features of the present disclosure, and are aimed to enable people who are familiar with the technology to understand the content of the present disclosure and implement it, and do not limit the scope of protection of the present disclosure. Any equivalent change or modification made according to the spirit of the present disclosure shall be covered in the scope of protection of the present disclosure.
