Why use medical silicone oil?

The progress of science and innovative medical device trends have led to the introduction of a variety of polymer materials in the medical field, medical grade silicones materials as organic compounds polymer materials play an important role, such as liquid silicone rubber LSR, and silicone oil. LSR can be applied in high-consistency rubber and silicone adhesive and can be used in implantable drug delivery devices. And why use medical silicone oil?

Due to medical-grade silicones oil properties of being gentle, pure, and non-irritating to the skin, medical-grade silicone oil can be used as a waterproof, moisturizing, and lubricating agent in the medical field. Mdecial-grade silicones oil can be used on the surface of the skin or on wounds to alleviate the feeling of dryness and stinging. Silicone oil can also be used to lubricate some medical devices to reduce friction and wear during use.

This article will discuss six aspects of medical silicone oils:

1. What is medical silicone oil?

Medical grade silicone oil is a Polyorganosiloxane liquid and its derivatives are used in the diagnosis, prevention, and treatment of disease or in medical devices to play a lubricating, defoaming function.

Broadly speaking, the cosmetic silicone oil used for skin care and beauty care also belongs to this category. Commonly used medical grade silicones oil for Polydimethylsiloxane, the use of its defoaming properties, can be made to treat abdominal distension of flatulence tablets and treatment of pulmonary edema aerosol, can also be used in abdominal surgery as a prevention of intestinal adhesions of anti-adhesive, in gastroscopy as a gastric defoamer and lubricants for some medical surgical instruments.

Medical grade silicone oil is required to be produced in a clean environment, with high purity, no residual acid, alkali catalysts, and low volatile matter, and is now mostly produced by resin method.

2. What are the features of silicone oil?

Medical grade silicones oil is made of bifunctional or monofunctional silicone monomer hydrolyzed and condensed into a linear structure of the oil. Commonly used are Methyl silicone oil, Ethyl silicone oil, and Methyl Phenyl silicone oil. Because medical-grade silicones have high chemical bond strength, good stability, compatibility, and other characteristics, silicone oil in the field of medical treatment is widely used.

Different from silicone adhesives, silicone oil is colorless, odorless, and tasteless, it has both glass and quartz properties, has good heat resistance, water resistance, resistance and chemical inertia, physiological inertia, and flexibility, and its liquid can be quickly diffused on the surface of other objects spread, the formation of the molecular thickness of the film so that the surface has a hydrophobic surface and reduce the surface of the adhesive force of viscous substances.

3. How to apply medical silicone oil?

Medical grade silicone oil is a colorless clarified oily liquid; odorless or almost odorless, tasteless. Medical-grade silicone oil is extremely soluble in Trichloromethane, Ether, or Toluene, and insoluble in water and Ethanol.

3.1 Used in the human body

If we try silicone oil material production for artificial larynx, heart valves, birth control, and other medical products, it is certainly with the human body's "appropriate" cooperation. Because the reaction with human tissue is very small, it can completely replace the human soft tissue, through the biochemical process and achieve the human body "assimilation".

3.2 Used as an antifoam agent

Medical-grade silicone oil can be used as an antifoam agent, its surface tension is small and can change the surface tension of bubbles so that they rupture.

Silicone oil antifoaming effect can be used to stop coughing, eliminate gas, and save the life of emphysema. Modern medicine believes that bronchial secretion blistering is usually the cause of cough, then the use of silicone antifoaming agent can make bronchial secretion blistering to achieve the effect of cough. In gastroscopy, taking silicone defoamer can also make the gastric lining more clearly observed while eliminating the accumulation of gas in the stomach and intestines after surgery. Especially in emphysema attack patients, the lung fluid will occur rapidly bubbling in a few minutes causing asphyxiation and death, and thus the use of non-toxic odorless silicone antifoam can save the life of such dangerous patients.

Medical grade silicone oil as an anti-foaming agent and defoamer for pharmaceuticals, usually only needs to add a very small dose, and can achieve extremely ideal results.

XJY-702 Methylhydrosiloxane/Dimethylsiloxane Copolymer

This product is non-toxic and tasteless, with active groups, under the action of catalyst, it can react with double bonds, hydroxyl groups, etc. It is the basic raw material of leveling agents, antifoam agents, water-soluble silicone oil, and other products.

3.3 Used in pharmaceutical products

Silicone oil has excellent hydrophobicity and reduces the adhesion characteristics, but also in medicine, it has great significance. Such as water-containing liquid medicine into a coated silicone oil bottle or ampoule, when used can be all poured out and drained, can achieve the purpose of using the full amount. Now widely stored penicillin suspension or powder ampoule coated with silicone oil, can be injected when the penicillin solution can quickly flow along the inner wall, is easy for medical personnel to carry out the operation of emptying and punctual pumping out of the contents of the drug.

And medical silicone oil can be used as a lubricant and polishing agent for tablets and capsules, brightening, anti-adhesion, and moisture-proofing for tablet granulation, tablet pressing, and coating, coolant for controlled and slow-release preparations, especially for drop pills;

Medical silicone oil also can be used as a reservoir for transdermal drug delivery preparations with strong fat solubility and used as a suppository release agent, defoamer in the extraction process of traditional Chinese medicine;

XJY-706 Tetramethyldisiloxane

It is soluble in aromatic hydrocarbons/petroleum hydrocarbons and other organic solvents, not in water, it is a kind of silicone intermediate with a wide range of uses, it is usually used as a silicone capping agent, and it can also be used as a pharmaceutical intermediates medical grade materials.
