Silicone oil and silicone emulsion are two different forms of silicon compounds, and the main differences are physical form, composition and application fields.
1. Physical form
Silicone oil: It is a colorless and transparent oily liquid at room temperature, with a wide range of viscosity, from low viscosity to high viscosity.
Silicone emulsion: The water-in-oil (O/W) or oil-in-water (W/O) emulsion formed by emulsification of silicone oil, usually has a milky white appearance.
2. Composition
Silicone oil: The main component is polydimethylsiloxane (PDMS), and its molecular weight determines its viscosity.
Silicone emulsion: It is composed of silicone oil, emulsifier and water. The emulsifier helps silicone oil disperse in water to form a stable emulsion.
3. Stability
Silicone oil: It has stable chemical properties, is resistant to high temperature and oxidation, and is not easy to decompose.
Silicone emulsion: It has poor stability and may stratify or demulsify after long-term storage, so stabilizers need to be added.
4. Application fields
Silicone oil:
Lubricant: It is used in machinery, electronic equipment, etc.
Defoamer: used in food, pharmaceutical and other industries.
Cosmetics: used as a lubricating ingredient in skin care products.
Release agent: used in rubber and plastic products.
Silicone emulsion:
Textile treatment: used as a softener and waterproof agent.
Cosmetics: used in lotions, creams, etc.
Paint: used in architectural paints to improve waterproofness.
Agriculture: used as a pesticide adjuvant to improve adhesion.
5. Usage
Silicone oil: can be used directly or diluted.
Silicone emulsion: needs to be diluted with water before use to facilitate uniform dispersion.
6. Environmental impact
Silicone oil: not easy to degrade, may have long-term impact on the environment.
Silicone emulsion: because it contains water, it is relatively more environmentally friendly, but emulsifiers may cause pollution.
