Nanoemulsions
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Nanoemulsions are submicron-sized emulsions that consist of oil and water phases stabilized by surfactants, often in the nanometer range (typically 20-200 nm). They are used in various industries, including pharmaceuticals, cosmetics, food, and agriculture, mainly to improve bioavailability, stability, and delivery of active compounds.
Key Features
- Particle size typically between 20-200 nanometers
- Enhanced bioavailability and absorption of active ingredients
- Stable physical and chemical properties due to small droplet size
- Versatile applications across pharmaceuticals, cosmetics, and food sectors
- Require surfactants for stabilization
- Can be prepared using high-energy methods (e.g., ultrasonication) or low-energy methods
Pros
- Improves solubility and bioavailability of poorly water-soluble compounds
- Offers enhanced stability and controlled release properties
- Reduces the need for high surfactant concentrations compared to traditional emulsions
- Facilitates targeted delivery in pharmaceutical and cosmetic formulations
Cons
- Preparation can be complex and require specialized equipment
- Potential stability issues over time if not properly formulated
- Use of surfactants may cause sensitivity or side effects in some users
- Cost of manufacturing may be higher compared to conventional emulsions
