An Summarize of Emulsifying Silicone Oil
1.Basic Information for Emulsifying Silicone Oil
Silicone oil is a new type of green and environmentally friendly material with many excellent properties, such as outstanding high and low temperature resistance, extremely low glass transition temperature, very low surface tension and surface energy, high hydrophobicity, very low solubility parameters and Dielectric constant, etc.
And have been widely used in textile finishing agents, leather finishing agents, cosmetics, waterproof materials, coatings and photosensitive materials. Since the application of silicone oil in the 1970s, more than 30% of cosmetics in Europe and the United States have added silicone oil of different specifications.
However, due to its hydrophobicity, it is difficult to disperse it in the water phase, so its application in some aspects is limited by Chemical book, and the emergence of emulsified silicone oil solves this problem. Driven by the wide application of emulsifying silicone oil, the formulation research of silicone oil emulsifier is also constantly improving, and the emulsifier formulation with convenient, low cost and better emulsion effect has a broader market prospect.
Emulsifying silicone oil is a milky white viscous liquid. Odorless. Insoluble in water but dispersible in water. Insoluble in ethanol, methanol, soluble in aromatic hydrocarbons, aliphatic hydrocarbons and chlorinated hydrocarbons. It is made of polymethylsiloxane and fumed silica mixed and rolled into silicone grease, and then polyvinyl alcohol, Tween 80 and deionized water are added.
Emulsifying silicone oil is properties White viscous liquid, insoluble in ethanol, methanol, soluble in aromatic hydrocarbons, aliphatic hydrocarbons and chlorinated hydrocarbons (such as benzene, carbon tetrachloride, etc.). In addition, emulsified silicone oil has excellent chemical stability, heat and cold resistance, weather resistance, lubricity, hydrophobicity and low surface tension, and is non-toxic and harmless to the human body, making it widely used in personal care, food production, fermentation industry, etc.

3. chemical application
Emulsifying Silicone Oil can be used in hair care products. Leather brighteners, automotive, furniture, flooring, metal processing, polyurethane, plastic, rubber, glass, ceramics, stone, textile, paper, wood and other industries. Anti-stick action, rust prevention of metals, soft and combing additives for shampoos, defoamers for cleaning and waterproofing and water-based coatings, etc.
1) Application in shampoo
Dimethyl silicone oil is widely used in motors, electrical appliances and electronic instruments as an insulating medium for temperature resistance, arc corona resistance, corrosion resistance, moisture resistance and dust resistance. Wait. Emulsifying Silicone Oil is used as liquid shockproof and damping material in various precision machinery, instruments and meters.
Solve the problem of astringency (that is, not smooth feeling) in the contact area between the hair and the shampoo when combing wet (especially when the hair is half-wet and half-dry). This problem is obvious even for the famous Procter & Gamble products (this is the reason for the improper selection of silicone molecular weight distribution). The astringency generally disappears when the hair is first dry, and it is clearly manifested in the noon and afternoon of the next day, and it persists after that, which is very unpleasant. This is the major drawback of current shampoos.
Emulsifying Silicone Oil has a significant conditioning and conditioning effect, leaving the hair with a unique silky soft feel, soft and elastic, and the hair is not greasy, suitable for long-term use. Long-term use can keep the hair uniquely silky soft and super-structured, unlike other silicone oils, which start to soften and harden after multiple uses.
The formula requirements are loose and not harsh. Some Emulsifying Silicone Oil require very harsh conditions (very precise amount of surfactant and cationic polymer) and the effect is not so good.
To make hair soft, emulsifying silicone oil with a specific molecular weight distribution must act on the hair in a specific environment, and it is this “specific” condition that we have studied for many years. Certain cationic quaternary ammonium polymers also provide long-lasting softness to hair, but are much less effective than silicones. Only silicones with a specific molecular weight distribution can exert a super rational and soft feeling on the hair.
If you want to pursue the perfect soft feeling of the hair, the silicone control must be strict! Foam interferes the most with the distribution and action of silicone on the hair. And this “special environment” is nothing more than the use of silicone in a certain concentration of surfactants in combination with the cationic polymer of the one.
2) Application in Food
Emulsifying silicone oil can be used as a food additive, a defoamer for monosodium glutamate fermentation and pharmaceutical production.
Food grade emulsifying silicone oil is a silicone defoamer mainly composed of methyl polysiloxane (silicone oil), and is a milky white liquid emulsified by adding a dispersing auxiliary.
Food grade emulsifying silicone oil properties:
- It is a non-polar compound and does not interact with water or substances with polar genes, so it has a strong defoaming effect and a very low dosage.
- The chemical properties are stable, and the secondary dew gas does not gel, nor does it interact with the product.
- It has high temperature resistance and chemical resistance, and can fully exert its defoaming effect in high temperature conditions, acidic and alkaline media.
- Low toxicity, no toxicity is proved by domestic and foreign clinical trials. The United States, the United Kingdom, Japan, France and other countries are legally designated as defoaming agents for the food chemical industry.
3) Application in health care
Emulsifying silicone oil s non-toxic to the human body and is not decomposed by body fluids, so it is also widely used in medical and health services. Utilizing its defoaming effect, the oral gastrointestinal defoaming tablet and the pulmonary edema defoaming aerosol have been prepared for medicinal purposes. Adding silicone oil to the ointment can improve the penetration ability of the drug into the skin and improve the efficacy of the drug. Some ointments based on silicone oil have good curative effects on scalds, dermatitis, bedsores, etc.
The anticoagulant effect of silicone oil can be used to treat the surface of the blood reservoir and prolong the storage time of blood samples. Also acts as a condom wet lubricant, and it does not kill sperm.
4) as defoamer
As a defoaming agent, because emulsifying silicone Oil has low surface tension and is insoluble in water, animal and vegetable oils and high-boiling mineral oils, it has good chemical stability and is non-toxic. As a defoaming agent, it has been widely used in petroleum, chemical, medical , pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries, as long as 10-100PPM of silicone oil is added, it has a good defoaming agent effect.
However, with the technology used in chemical coloring engineering, there are many other uses. Listen to what the Dimethyl silicone oil manufacturer (Great Spring)has to say. Emulsifying Silicone Oil has many other uses. For example, using its high flash point, odorless, colorless, transparent and non-toxic to human body, it can be used as a heat carrier in oil baths or thermostats in steel, glass, ceramics and other industries and scientific research.
Using its good shear resistance, it can be used as hydraulic oil, especially aviation hydraulic oil. Using it to treat rayon spinning head can eliminate static electricity and improve the quality of spinning. Adding silicone oil to cosmetics can improve the moisturizing and protective effect of the skin and so on.
3.How to use Emulsifying Silicone Oil
Emulsifying silicone oil is widely used as a release agent for various materials such as plastics, because of its excellent high and low temperature resistance, light transmission, electrical properties, water irritability, moisture resistance, chemical stability and low volatility. Therefore, it is widely used for high temperature operation release of large moldings, such as phenolic resin and unsaturated polyester laminates. In order to meet different needs, silicone oil is usually processed into different forms such as solution, emulsion and silicone paste.
Moreover, taking simethicone water before capsule endoscopy can effectively remove air bubbles in the small intestine. Simethicone can improve the clarity of the observation of the small intestine mucosa during capsule endoscopy, and is related to its dosage. It has no effect on the passage time of the small intestine. Influence. a solution. Dissolve silicone oil in carbon tetrachloride, toluene or xylene to make a solution with a concentration of 0.5%~2%. Suitable for use at 60~110℃.

4.How to clean
When cleaning dimethyl silicone oil, too high viscosity silicone oil is also difficult to clean, so the cleaning silicone oil must have the following characteristics:
- Emulsifying silicone oil with low viscosity such as below 1000
- Make sure that the silicone oil is not cured, and the cured silicone oil is difficult to wash off
- Make sure it is silicone oil and there is no other oil stains.
For the cleaning of Emulsifying Silicone Oil, various cleaning agents emerge in an endless stream in the industry and are applied to different production and processing. Emulsifying Silicone Oil cleaning agent can effectively clean uncured low-viscosity silicone oil stains without adversely affecting the surface of the workpiece.
The use of Emulsifying Silicone Oil cleaning agent is recommended to be used with ultrasonic cleaning. However, cleaning methods such as spraying (large products), soaking and other cleaning methods are also used in different industrial scenarios. 1:10-50 open diluted before use, the water temperature can be controlled at 50-60 degrees Celsius, rinse with water after cleaning, and dry it, in the fields of precision electronic components, clean clothes, rubber gloves, etc. Get a good application.
