The Chemists Can Design And Produce Specialty Chemicals

Monday, August 3rd, 2009

A useful aspect of specialty chemicals is that they can be custom designed to meet the specifications of a particular product or process. The important thing to understand is that every chemical is made up of molecules that are in turn made up of different combinations of atomic elements. Each element has its own special set of chemical and physical properties, and depending on the combination of elements that are used, the chemical substance will have certain chemical and physical properties of its own.

These chemical properties are, overall, dependent on one hugely important factor: the number of electrons that a single atom of a single element is made up of. Amazingly enough, for example, the sole basic difference between elemental oxygen and elemental carbon is that an atom of oxygen has eight electrons, while an atom of carbon has six. This basic difference means that each element has entirely different physical and chemical properties. This might seem like a rather long-winded explanation, but it’s important for understanding how a chemist can design various types of specialty chemicals, because the ways in which various different elements react is also determined largely by the number of electrons an atom of each element contains.

Another important concept is that an atom of any element has a series of layers of electrons, called shells, and with the exception of the innermost shell, each can hold up to eight electrons. An atom that doesn’t have a filled outer shell will form chemical bonds with other atoms, if it can, to fill that outer shell. An atom of elemental fluorine, for example, has a total of nine electrons, and has an outer shell that is ‘missing’ one electron. It’s this atomic structure that makes fluorine a highly reactive element when it’s present in its pure form. You could say that fluorine ‘wants’ to react with other chemicals so badly that it will react with almost anything in its efforts to fill up that outer shell. This makes fluorine-and other halogen gases-quite important in the production of certain specialty chemicals. These halogen gases form compounds that are highly stable, because of their special atomic structure.

This made seem like an incredibly complicated business to an ‘outsider’ who isn’t familiar with chemical processes. To the chemists who design and produce specialty chemicals, it’s second nature. Chemists have the background knowledge-the understanding of all the different properties of each element-that allows them to design specialty chemicals that have the desired properties. With knowledge of the different chemical and physical properties of elements and molecules, specialty chemists can design and produce chemicals that are inert and non-reactive at high temperatures, chemicals that repel water or dirt, that are used as lubricants, or as pharmaceutical drugs. The key is that the designer understands how to combine elements and chemicals to come up with a finished product with the chemical and physical properties that are needed.

Your Face With A Facial Chemical Peel

Tuesday, June 2nd, 2009

One way to improve your appearance is to undergo a facial chemical peel, which are used to treat photo aging, wrinkles, scarring, acne, precancerous lesions, and discoloration. A facial chemical peel causes injury to the skin, but promoting new skin to grow, giving your skin an improved more youthful appearance.

The procedure can be done in less than an hour, depending on the size of the area that needs treatment. There are different kinds of peels, and each one is performed differently. Very light peels penetrate only the dead skin cells on top of the epidermis and do not injure your skin. Light peels to deep peels; progressively injure your skin more, depending on the condition of the skin being treated, and the desired final look. After the facial chemical peel, your skin may require some down time in order to recover. If you experienced a light to medium peel, you will endure very limited side effects, but with a deeper peel, healing may takes weeks.

Facial chemical peels have been proven to be a safe and effective method to achieve the desired look. In fact, they have been used for hundreds of years and have a safe record if used with the proper hands. The procedure however, is not for everyone, and if you are seriously considering undergoing with a facial chemical peel, be aware of the potential side effects that can arise due to your general health, susceptibility to scarring, and or skin diseases. A skin care physician will be able to best decide if the procedure is right for you.

The cost of a facial chemical peel ranges from a few hundred to a thousand dollars. It all depends on the depth of the peel and how many are required to achieve the look that you desire. You will be able to notice the success of the peel after the first treatment, and be able to better estimate how many more are needed and what the costs there will be overall. Results will generally last months to years with good sun protection, depending on the depth of the peel. The deeper the peel, the longer lasting are the effects.

The facial chemical peel is also a good precursor as to what the rest of your skin should look and feel like. If you are worried about any cancerous lesions on your face and desire a peel, seek a physician to find out if other parts of the body that have had significant sun exposure need examination and treatment for any possible cancerous areas.
