Let's look at several popular grease-based ointments that are sold in pharmacies. You can also make an ointment with grease for psoriasis yourself .

Solid oil - description, characteristics and applicability.

Solidol is one of the first greases developed in the 20s of the 20th century for servicing components of automotive and agricultural equipment.

Solid oil

(from Latin solidus - dense and oleum - oil), outdated designations “grease”, “madia”, “oil ointment”, this is a plastic lubricant obtained by thickening industrial oils of medium viscosity with calcium soaps of higher fatty acids.

Operating temperature up to 65…70 °C. Compared to lithium greases, it is more difficult to wash out with water.

Solid oil is used in mechanisms that operate in damp conditions (agricultural machinery, etc.), but do not experience heating, and also as a conservation lubricant.

The composition of grease is a homogeneous composition from light yellow to dark brown, which is obtained by thickening industrial oils with calcium soaps. The upper threshold of operating temperatures is about +70 °C.

Solid oils are used not only for lubricating machines and mechanisms, but also for medicinal purposes. In gardening, the positive practice of using solid oil “in its pure form” instead of garden varnish when grafting and pruning trees is known.

There are two main types of solid oils:

  • Fatty greases, where fatty acids of plant origin are used as a thickener,
  • Synthetic solid oils, where the thickener is obtained by chemical synthesis.

Solid oils are divided into two main groups:

  • Fatty
    solid oils, where hydrated calcium soaps are used to thicken the base oil, obtained by saponification of fatty acids and their glycerides that are part of vegetable oils with slaked lime.
  • Synthetic
    solid oils, where hydrated calcium soaps of synthetic fatty acids, obtained by catalytic oxidation of high-molecular hydrocarbons (paraffins, etc.) with atmospheric oxygen, are used to thicken the base oil.

Diet

We have already said that solid oil helps get rid of psoriasis quite quickly. But the effect will be much better if you follow a certain diet. If you consult a doctor about this problem, he can prescribe medication and some painless procedures.

Let's pay a little attention to proper nutrition. For psoriasis you should eat:

  • vegetables;
  • fruits;
  • berries;
  • greenery;
  • dairy products;
  • eggs;
  • poultry meat;
  • fish;
  • beef;
  • cereals;
  • vegetable oils.

Do not use:

  • citrus;
  • potatoes;
  • eggplant;
  • tomatoes;
  • Bell pepper;
  • alcoholic drinks;
  • chocolate;
  • coffee.

It is also worth saying that you should not smoke. If a person smokes, then it is worth reducing the number of cigarettes smoked per day to a minimum. Follow the rules of the diet, use grease-based ointments, then you will be able to get rid of psoriasis quickly.

Synthetic solid oil - production.

Synthetic solid oil was produced on the basis of acid-contact and selectively refined oils, and the share of the latter in the mixture, according to standards, did not exceed 30%. Bottom residues from the distillation of synthetic fatty acids (9-12%), which were saponified with lime, are used as raw materials for the preparation of the thickener.

Fatty solid oil is thickened with calcium soaps of fatty acids contained in natural fats (usually cottonseed oil).

To prepare synthetic solid oil, a suspension of lime milk is prepared in a digester in a small amount of ready-made solid oil at a temperature of about 100 °C. Then the temperature drops to 65 ° C and the mixture settles, the water released is drained, and in return, a small (about 15% of the norm) amount of mineral oil and the entire required amount of fatty acids are loaded into the boiler.

The next stage in the preparation of synthetic solid oil is the saponification of acids and partial dehydration of the resulting soap by heating the mixture to 105 °C for 2...6 hours. The rest of the oil is added to the mixture, which reduces its temperature to 70...75 °C. After mixing and cooling, the finished solid oil is poured into containers. At modernly equipped enterprises, the cooking of solid oils was carried out under pressure in hermetically sealed autoclaves with mechanical mixing devices, which accelerated the process of preparing the lubricant and increased productivity, and refrigerating drums were used to cool it.

Both types of grease are prepared from mineral (petroleum) oil; the names reflect the method of obtaining the soap thickener used.

Fatty solid oils were considered to be of higher quality, in particular, they were less prone to hardening during storage and to thixotropic hardening during “rest” after injection into the unit under pressure. Externally, fatty solids are indistinguishable and mix without negative consequences.

Based on their consistency, they also distinguish between regular and press grease.

Press greases are used to lubricate mechanisms through grease fittings (injection), they are softer in consistency, but have a lower upper temperature threshold and decompose already at 80 °C (they begin to leak and lose their lubricating properties at 45...50 °C) .

Solid oils include USsA graphite lubricant, which has a silver tint. Its composition includes up to 10% ground graphite-P (coarse), this gives the USsA graphite lubricant increased extreme pressure and conductive properties and.

Solid oils have been used everywhere for many years. Due to their low cost, versatility, good moisture resistance, even today they still find use.

Grease turned out to be so popular that not only mechanics, but also ordinary car enthusiasts began to call any grease for automotive and industrial applications grease.

The main disadvantage of solid oil is the very low threshold for upper operating temperatures. Already at +80 °C the lubricant is destroyed and ceases to perform its protective functions.

How to make ointment for psoriasis based on grease with your own hands at home

You can treat psoriasis with solid oil not only with pharmaceutical ointments. Among the recipes of traditional medicine there are quite a lot of such compositions, and some use the pure product.


The most common components of such drugs are the following:

The main rule when preparing such ointments is to strictly follow the recipe.

Recipe with honey and celandine

Solid oil cream with the addition of honey and celandine is prepared according to the following proportions:

These components are thoroughly mixed until a homogeneous viscous mass is obtained and left for 7 days. The product must be applied to cleaned lesions 1-2 times a day. The full course of treatment is limited to 2-2.5 months.

Recipe with butter and egg

Solid oil composition with the addition of eggs and butter is easier to prepare.


Composition proportions:

  • egg white – 1 pc.;
  • melted butter – 15 ml;
  • grease – 100g.

The components are mixed until smooth, and after 3 hours the ointment is ready for use.

It is applied to cleansed and dried skin in a thin layer. Duration of use is at least 1 month.

Litol - description, characteristics and applicability.

Litol grease was developed in the Soviet Union in the 70-80s of the 20th century as a material that, over time, is intended to completely replace grease.

Mineral oil thickened with lithium soaps of stearic acids is used as a lithol base. This thickener made it possible to expand the range of operating temperatures - the lubricant works perfectly up to +120...+130 °C.

The most famous and versatile material from the series is Litol-24. The additives this composition contains prevent the process of accelerated oxidation of the lubricant. The consistency, load-bearing capacity, water-repellent properties and many other characteristics of the material turned out to be sufficient for its use in most components of modern mechanisms.

Currently, Litol is perhaps the most universal and multifunctional lubricant for mechanisms operating under normal operating conditions.

Reviews

Reviews about the treatment of psoriasis with solidol-based products from 99% of people are positive. Pay attention to the ointments that were listed in this article. Before using any product, consult your doctor and read the instructions for use.

Psoriatic disease belongs to the category of incurable pathologies with cyclic recurrence. This disorder is accompanied by significant changes in the skin, both in a small volume and with damage to large areas. The result of such manifestations is the constant presence of discomfort and irritation. Regardless of the long period of research conducted on the treatment of psoriasis, no final solution has been found.

The only option is to eliminate symptomatic signs and achieve a long period of remission, for which a variety of physiotherapeutic procedures and topical formulations are used. Experts and patients recognize the treatment of psoriasis with solid oil and ointments based on it as one of the most effective methods.

Comparison of solid oil and lithol.

So, since the times of the USSR, litol and grease have remained the most popular lubricants in Russia.
What is the difference between these materials? You can understand lubricants, which is better - litol or grease, if you know their composition and the properties that their components give to lubricants.

The main features and differences between the materials are explained by the different type of thickener used.

The increase in the heat resistance of the composition is the merit of lithium soap, used instead of calcium soap in grease. Litol also has higher anti-corrosion properties.

But, if we compare both compositions, calcium solid oil better resists being washed out by water. It is also characterized by less chemical activity and can be used with those structural materials (for example, aluminum and other non-ferrous metals) for which lithium greases are destructive.

One cannot fail to note such a parameter as plasticity. If you squeeze lithol in one hand and solid oil in the other, the first material will be smeared, and the second will be pressed well between your fingers.

Unlike solid oils, lithols do not contain components that are aggressive towards most rubbers. That is why these materials are often used in units in contact with rubber cuffs, oil seals, and seals.

Thus, despite the obvious advantages of lithol in some parameters, the difference in operational properties did not allow lithol to completely replace solid oil. Each of these materials is still in use, each with its own areas of application.

Note that pure calcium lubricants are now rarely used. They were replaced by materials based on complex calcium soaps. The new compositions are free of the disadvantages inherent in lithols and are characterized by very high performance properties.

Areas of application

The difference between ordinary and medical solid oil is only in its purification from impurities and petroleum product residues. Medically used in the treatment of psoriasis. Scientists have proven its effectiveness in this case.

Externally, it is a thick, greasy ointment with a brown tint, which has the following beneficial properties:

  • prevents peeling;
  • activates cell regeneration;
  • heals wounds and ulcers;
  • eliminates itching and burning.

After doctors confirmed the healing properties of solid oil, they began to add it to many medications intended for the treatment of psoriasis, eczema and other skin diseases.

Among the most popular and effective means it is worth highlighting:

  • "Ungwetol";
  • "Magnispor";
  • "Antipsor";
  • “I. S. Chernyshev’s ointment”;
  • "Cytospor";
  • "Psorium";
  • "Psoril";
  • "Psori cream."

And although solid oil has been used for medical purposes in our country for more than 80 years, you should know that it causes allergies in the form of redness and pimples.

Use for psoriasis

The course of treatment of the disease with ointments and grease should not last more than two months. This period is enough to get rid of acute signs of the disease and restore the skin. Kartalin ointment, also known as White Salidol , is widely used in dermatology.

What is better to choose for lubrication - litol or solid oil?

  • Solid oil is often used to lubricate hinges and other friction units of outdated equipment that does not experience heavy loads and operates at low speeds.
  • Litol can withstand more severe conditions, therefore it is actively used in components of modern technology.

At the same time, restrictions regarding a particular lubricant impose certain limits on its use in certain areas.
For example, lithol is not recommended for use on aluminum surfaces, so if there is an alternative - to use grease or lithium grease there - it is better to choose the first option.

Solid oil is indispensable where good protection from environmental influences is required - moisture, dust, dirt, sun, wind. That is why it is used as a conservation lubricant, as well as for agricultural machinery and road equipment.

In modern automotive technology, the use of grease is undesirable and impractical, and sometimes unacceptable. The use of grease is suitable for use on outdated equipment with large lubrication gaps and lower loads on components and parts.
Solid oil is excellent as a lubricant for conservation, where solid oil is indispensable. Litol is the most universal lubricant for most automotive mechanisms.

How to properly smear psoriatic plaques

In order to correctly apply the grease product to the areas of skin affected by psoriasis and get the maximum degree of effectiveness from the treatment, you must follow the following rules:

  1. Before using the ointment, the treated area should be washed with warm water. This will soften the psoriatic scales, which will speed up the absorption of the product into the skin.
  2. The duration of preservation of the ointment on the body after application is determined according to the instructions or is limited to 12 hours.
  3. It is recommended to cover the treated areas with plastic wrap to speed up absorption; in particular, when applied at night, this will ensure the cleanliness of the bed linen.
  4. You can wash off grease ointments with classic skin care products. After washing, it is recommended to lubricate the body with moisturizing cream or oil.
  5. The recommended course duration for the use of such drugs is at least 60 days. Exceptions have excellent deadlines according to the instructions.
  6. After the disappearance of psoriasis symptoms, use should be extended for 14 days to consolidate the effect.
  7. If an adverse reaction occurs in the form of itching and irritation, you should consult a specialist and begin antihistamine therapy.
  8. Be sure to use the medications and follow the diet prescribed by your doctor.
