Gel

Gel is a unique dispersed system that has the properties of both a solid and a liquid. Basically, the gel is a suspension that has a jelly-like appearance. Gels are widely used in various industries - from medicine to cosmetics and industry.

One of the most common areas of application of gels is medicine. Some medications are prescribed in the form of gels for external use. Gels can be used for topical treatment of various skin diseases, such as eczema, psoriasis, burns, as well as to reduce pain and inflammation.

One of the advantages of gels is their ability to localize to the desired location, since they do not spread quickly and can remain on the surface of the skin or mucous membranes for a long time. In addition, gels can provide stability and maintain the activity of drugs for a long time.

In cosmetology, gels are used for various procedures - from skin care to procedures for strengthening nails and hair. They have a delicate texture that does not leave a sticky feeling and is quickly absorbed into the skin, providing it with the necessary care.

Gels are also widely used in industry. They can be used as adhesives, sealants, lubricants and other materials. Gels provide long-term protection of surfaces from moisture, aggressive environments and other external factors.

Despite all the advantages of gels, they also have some disadvantages. They can be more expensive than other dosage forms and often require special storage conditions. In addition, some people may experience allergic reactions to the ingredients contained in the gels.

In conclusion, gel (Gel) is a dispersed system that has wide application in various industries, from medicine to cosmetics and industry. They have unique properties that allow them to be effective and easy to use. However, like any other dosage form, gels have their own advantages and disadvantages, which should be taken into account when choosing the most suitable treatment method.

Here is my article on this topic:

- Gel is a dispersed system with a viscous consistency in the form of a suspension. It is obtained by mixing and dispersing a paste-like substance with a liquid carrier, forming a ready-to-use medicinal product. Most often, the system is designed for introduction into the body - as a patch, ointment form, syrup or over-the-counter drug.

Description and properties of the gel

The structure and consistency of the gel resembles jelly or paste, but liquid is still present inside. The consistency is achieved by adding more liquid to the mixture. The gel can be obtained from various components, including paraffins, silicones or vegetable oils. It has the following physical characteristics: - More plastic than ointment - Possibly has adhesion

**Gel** is a drug that has properties characteristic of a solid body, although it is a fluid medium, allowing the administration of active substances through mucous membranes, various wound surfaces, and the gastrointestinal tract. The appearance of the gel depends on the substances included in it and on the manufacturing method. Liquid preparations with plastic properties, after mixing with liquid, form a more viscous consistency. If a substance in the gel produces a viscous homogeneous solution, which needs to be given such a consistency, it should have a dispersion of about 0.1–1 microns. The concentration effect is achieved due to the fact that this amount of the applied mixture is essentially a more powerful adhesive agent, which provides an increase in viscosity, creates a thicker layer, under the influence of which the connection with the mucous membrane is enhanced. The gel has the same pharmacological properties as the paste form (cream, ointment), and the pharmacological action of the individual components of the formulation is represented either by the dispersed phase or by the outer layer that moisturizes the mucous membrane. Considering that the properties of the fat base determine the therapeutic effect, it must be characterized by the following requirements: It must not have allergenic or irritating properties; Should be easily absorbed by the patient’s body; Cause minor formation of intestinal gases.

A gel is a liquid, homogeneous mixture that is similar to a liquid but produces a film when applied to the skin. It is obtained by dissolving or emulsifying one substance in another substance or mixture of substances. The gel may contain active and inactive additives and excipients. The activity of gels lies in the ability for long-term storage, water and fat solubility. But they are less stable compared to mixtures.

Based on consistency, the gel is divided into:

with liquid base; gels with a pasty structure (film-forming); gel paste (plasticity is about average). The gel is a homogeneous viscous, pasty mass, which may consist of unrelated particles. This is a suspension in water and/or fatty oils, with the presence of cross-linking components
