Basic Info
Brief introduction
Silicone oil, a polydimethylsiloxane of varying degrees of polymerization, is a chain-like polydimethylsiloxane. The oil is made by hydrolyzing the dimethyl dichlorosilane in water to get a primary condensed rings. The ring will be cracked and distilled into a low ring. Next, the capping agent and catalyst will be mixed with the ring to produce various mixtures of different degrees. Silicone oil can be produced after vacuum distillation, which removes low boiling materials.
Silicone oil has a light yellow or colorless liquid that is non-toxic and non-volatile. Silicone oil has a high compatibility to many cosmetic components and is not soluble in water. This reduces the stickiness of the product. It can be used in a variety of products, including lotions, face cleansers and cosmetics.
The silicone oil is characterized by its excellent heat resistance and oxidation resistance. It can also be used at low temperatures for long periods of time.

Product Packaging

Silicone oil, also known as silicone polymer, is a type with silicon oxygen bond (- Si-O-) in the main chain, and organic groups such as methyl, Phenyl, etc. Side chains. It is used widely in the industrial, medical and everyday chemical fields.
1. Industrial sector
Lubricant for high temperature: Silicone oil can withstand temperatures between -50 and 250 degrees Fahrenheit. It is used to lubricate high-temperature bearings and precision instruments as well as automotive components.
Rubber/plastic lubricant: Add to plastic gears or seals to reduce noise and friction.
Foam control in oilfield drilling liquid: Defoamer for the petroleum industry
Food processing: Food-grade defoamers are used in fermentation tanks, syrup production and other food processing (must meet FDA standards).
Release agent for rubber/plastic products.
Metal casting: A release agent for die-casting aluminum alloys.
2. Cosmetics and Personal care
skin care products
Softener: It’s added to sunscreen and face cream to improve ductility (such as cyclopentamethylenesiloxane).
Use silicone oil to temporarily fill pores and as a pre-makeup lotion.
HAIR CARE
Shampoo/conditioner : Polydimethylsiloxane, or PDMS, repairs hair scales while increasing hair shine.
Thermal protection spray: for hair dryers and hair straighteners.
Makeup
Eye black and liquid foundation enhance water resistance and durability.
3. Medical and Pharmaceutical
Medical equipment
Lubrication: A lubricating layer on the surface the of the syringe and catheter.
Ultrasonic coupling agents: Improves the efficiency of sound waves conduction between the probes and the skin.
Drug carriers
Ointment matrix is used to release drugs from external skin medications (such as scargel).
Eye drops: silicone oil eye drops, such as polyethylene glycol silicon oil mixtures that relieve dry eyes syndrome.
Surgery
Vitreous substitute (high-purity silicone oil): injected into the eyeball for retinal detachment.
4. Home furnishings and daily necessities
Furniture care
Polishing agent for wood and leather surfaces, dustproof and waterproof.
Car Care
Car wax: improves gloss and hydrophobicity.
Interior protection: Anti aging coating on dashboard.
Textile processing
Softening agent: softens and wrinkle-resistant fabrics (such as bed linen and towels).
Waterproof treatment for outdoor clothing: Hydrophobic coating (compounds with fluorine).
5. Special Purpose
EADS
Extreme temperature resistance. Used to lubricate satellite components and seal materials on spacecraft.
Research and experimentation
Vacuum pump oil: Low volatility, chemically inert and high vacuum lubrication.
