Description of trichloroacetic acid
Wartner gel based on trichloroacetic acid
Trichloroacetic acid is hygroscopic, colorless crystals with a specific vinegar aroma. It is an analogue of acetic acid. In this case, 3 hydrogen atoms in the composition of trichloroacetic acid are replaced by chlorine atoms. The substance is highly soluble in water and is considered quite toxic.
This acid is easily absorbed through the skin and cauterizes the epidermis. This property is provided by the presence of chlorine atoms, which are involved in the process of releasing the proton, which has powerful acidic characteristics. Chlorine also promotes deep penetration of the substance through the fatty and protein barriers of the epidermis.
Depending on the amount of trichloroacetic acid in the water, the concentration of the solution may fluctuate. As a rule, less concentrated mixtures are used for cosmetic purposes - about 15-35%. For medical purposes, including the removal of warts, more concentrated solutions are used - from 80% and higher.
Trichloroacetic acid can be used to remove warts either in its pure form or in the form of pharmaceutical preparations based on it. A more preferable way to remove formations is with the use of pharmacological agents. They have an optimal concentration of the active ingredient and are safer to use at home.
Among the most popular drugs is Wartner gel based on trichloroacetic acid
. It does not spread over the skin due to its thick consistency, which prevents the risk of chemical burns. The product has a convenient release form in the form of a pen applicator.
The price of Wartner gel with trichloroacetic acid is 500-700 rubles in Russia (250 hryvnia in Ukraine).
In addition, you can purchase this acid in various concentrations at the pharmacy and use it spot-on to remove warts.
The price of trichloroacetic acid is 1500-2000 rubles in Russia (300-450 hryvnia in Ukraine) per kilogram.
You can purchase this substance in pharmacies, professional cosmetics stores, as well as from suppliers of chemical reagents.
Note! Analogues of trichloroacetic acid for warts are various concentrated acids, for example, acetic, salicylic, retinoic. All these substances are chemically active and burn the skin, and with it the wart.
Precautions when using the product
In order to minimize harm to the body when using vinegar essence, you must carefully ensure that the concentrated solution does not come into contact with the skin and mucous membranes. Otherwise, it may cause severe chemical burns.
If contact of the acid with the mucous membranes or skin could not be avoided, then the damaged area must be rinsed with plenty of water.
You also need to know about the contraindications for using this spice. For example, doctors do not recommend adding vinegar to food for people with stomach diseases (ulcers, gastritis) and other disorders of the gastrointestinal tract.
With caution and after consulting a doctor, you can use acetic acid for medicinal purposes for:
- diseases of the cardiovascular system;
- weak immunity;
- pregnancy and lactation;
- children under 3 years old and elderly people.
Important to remember! Regardless of dilution and concentration, vinegar is not recommended for use in enemas; vinegar lotions are contraindicated for people with sensitive skin.
Beneficial properties of trichloroacetic acid for warts
Trichloroacetic acid is a powerful chemical that should be used with caution. If all safety rules are followed, this substance can have a positive effect on the epidermis and eliminate warts of various types.
Important! Most often, trichloroacetic acid is used to remove common and plantar benign tumors caused by the human papillomavirus.
The beneficial properties of trichloroacetic acid in the treatment of warts are as follows:
- Cleansing . The substance literally removes the top layer of skin along with new growths, making the epidermis smooth and clean.
- Regeneration . Under the influence of trichloroacetic acid, the proliferation of skin cells increases. This leads to an improvement in the barrier and regenerative abilities of the dermis.
- Stimulation . The product helps to dilate the blood vessels of the epidermis. This leads to improved metabolic processes and enhances natural collagen synthesis.
In addition, this acid has an antibacterial effect, destroys pathogenic microflora, and also relieves the inflammatory process caused by the development and growth of warts.
Using trichloroacetic acid to combat warts is quite convenient. First, it is relatively safe when used correctly and has no overall toxic effects on the body. Secondly, you can visually control the depth of penetration of the substance by the nature of the “frost”, which is a consequence of denaturation of the dermal protein, which manifests itself in the form of lightening of the surface of the epidermis. Thirdly, trichloroacetic acid distributes well over the skin and gives quick results with minimal preparation.
In addition, the product has an additional effect on the skin of the feet, removes calluses, corns and rough epidermis along with warts.
Application
Monochloroacetic acid is an intermediate product in the synthesis of indigo and many other vat dyes; it is also used in the production of carboxymethylcellulose, the hypnotic barbital, herbicides (for example, salts and esters of 2,4-dichlorophenoxyacetic acid), and vitamin B6.
An illustration of its usefulness in organic chemistry is O
-alkylation of salicylic aldehyde with chloroacetic acid, followed by decarboxylation of the resulting ester, yielding benzofuran. [1]
Most reactions use the high reactivity of the C-Cl bond. It is a precursor to the herbicide glyphosate. The herbicide MCPAC (2-methyl-4-chlorophenoxy acetic acid) was obtained by alkylation with chloroacetic acid. Chloroacetic acid is converted to chloroacetyl chloride, a precursor of adrenaline.
Replacing chlorine with sulfur produces thioglycolic acid, which is used as a PVC stabilizer and sometimes as an ingredient in cosmetics. The largest amount of chloroacetic acid is used to prepare a thickener - carboxymethylcellulose.
Instructions for trichloroacetic acid for warts
It is recommended to treat at home only plantar or vulgar (common) warts, which are localized on the feet and hands.
Regardless of whether you use a pure concentrated substance or a preparation based on it, use trichloroacetic acid according to the instructions:
- Clean the surface of the leather you plan to treat.
- Apply a drop of the substance directly to the neoplasm.
- Try to avoid spreading the product onto healthy epidermis. To avoid getting it on the skin, first cover the area around the wart with a thick layer of any fatty cream or Vaseline.
- Make sure that the entire surface of the tumor is covered with a thin layer of trichloroacetic acid.
- If the wart is large enough, add one or more drops of the substance.
- Wait for the product to dry completely.
- There is no need to remove any remaining substance from the wart; immediately after drying, you can get dressed and begin your daily activities.
It should be understood that warts will not disappear in one procedure. You need to repeat this manipulation for at least 4 days in a row. As a rule, the tumors will disappear within 10 days.
In the first 4 days of using trichloroacetic acid, the warts will gradually peel off along with the epidermis. You can gently facilitate this process by exposing your skin to running warm water from time to time. Do not peel off the crusts!
A few days after the start of treatment, a pinkish area of healthy skin will appear at the site of the wart. Sometimes, as the tumor dies, it darkens. This is normal. The full course of skin restoration can last up to several weeks.
Note! If the tumor is located on a sensitive area of the foot and it causes discomfort when moving, you should protect the skin with a bandage.
Contraindications to the use of trichloroacetic acid
Trichloroacetic acid is a fairly potent chemical. It should be handled with extreme caution so as not to harm the skin. In addition, it has a number of contraindications.
Let's look at them:
- Trichloroacetic acid should not be used on hypersensitive skin, or applied to the face or intimate area.
- Warts should not be treated with trichloroacetic acid if the skin area contains seborrheic keratosis, fibroids, moles, heavy pigmentation, and molluscum contagiosum.
- During pregnancy and lactation, trichloroacetic acid should not be used.
- Diabetes mellitus of both types is also a contraindication to the use of this substance.
- Warts should not be removed from children under 4 years of age.
Important! If there is the slightest doubt that the skin growth is a wart, the use of trichloroacetic acid must be agreed with a dermatologist.
Also, you should not combine this substance with other drugs to remove benign tumors.
If trichloroacetic acid gets on a healthy area of skin, it should be removed immediately with plenty of running water.
Carrying out the procedure
It is best to entrust this procedure to an experienced cosmetologist in order not to harm the skin. He will be able peeling solution
Before peeling, the face is treated with lotion to remove remnants of decorative cosmetics and fat from the skin surface of the face. After this, the prepared TCA peeling solution is applied. The chemical composition of the product affects everyone differently; the first layer can cause very unpleasant sensations in the form of pain and burning. Others tolerate it calmly, their skin reacts painlessly.
Much will depend during peeling on the concentration of the composition; the higher it is, the stronger the burning sensation. In any case, such pain is quite tolerable and lasts a short time.
The procedure takes approximately 20 minutes . White spots may appear on the skin - coagulated epidermis. Redness and a pronounced vascular reaction will also appear. All this does not last long, for 2-4 days after the session.
Literally after 2-3 days, darkish crusts appear on the skin. You cannot touch them and they must come off on their own, otherwise scars may remain on the skin. After about a week, the crusts will completely come off naturally. Underneath, new, young skin will appear with a beautiful and fresh pink color. After 7-10 days, the skin surface will be completely renewed and become rejuvenated, elastic and firm.
Results of using trichloroacetic acid
In most cases, it is enough to apply the substance 4 times for the wart to begin to die and eventually disappear completely.
Visible results after using trichloroacetic acid usually occur within a week. If the wart is old or there are extensive skin lesions, then the course of treatment may need to be extended.
Trichloroacetic acid has a detrimental effect on the affected tissue, thus cleansing the epidermis of neoplasms. In addition, the substance eliminates the human papillomavirus, which prevents the spread of infection throughout the body and prevents warts from reoccurring.
