PEG-40 Stearate
Ingredient Info
PEG-40 Stearate is an emulsifier—a ingredient that helps mix oil and water together in creams and lotions. It's derived from stearic acid (a fatty acid) combined with polyethylene glycol, and is commonly used to create smooth, stable formulations that won't separate over time.
Benefits
- Stabilizes cream formulations to prevent separation
- Helps create a smooth, uniform texture
- May enhance penetration of active ingredients into the skin when used in microemulsion systems
Science: Research shows PEG-40 Stearate functions effectively as part of stable emulsifier systems in topical cream formulations and has been investigated as a component in microemulsion vehicles designed to improve skin penetration of active ingredients. It is recognized as safe for cosmetic use by regulatory bodies.
