Polysorbate 20 is a water-soluble, nonionic surfactant that belongs to the polysorbate family. It is commonly used in the cosmetic and pharmaceutical industries for its emulsifying, solubilizing, and dispersing properties. Here are some key points about polysorbate 20:
Emulsifier: Polysorbate 20 is often used as an emulsifying agent, helping to disperse and stabilize oil-in-water emulsions. This makes it useful in various cosmetic products like lotions, creams, and liquid formulations.
Solubilizer: It can solubilize or dissolve essential oils and other hydrophobic substances in water-based formulations, enhancing the compatibility of different ingredients.
Stabilizer: Polysorbate 20 contributes to the stability of formulations by preventing the separation of oil and water phases.
Mild Surfactant: It has mild surfactant properties, making it suitable for gentle cleansing products like baby shampoos and facial cleansers.
Hydrophilic-Lipophilic Balance (HLB): Polysorbate 20 has a specific HLB value, indicating its ability to form stable emulsions. Its HLB value makes it suitable for use in water-in-oil emulsions.
Versatility: This ingredient is versatile and is often used in combination with other emulsifiers and surfactants to achieve specific formulations and desired textures.
It's important to note that polysorbate 20 is generally considered safe for use in cosmetics when used as directed. It's commonly found in a variety of personal care products, providing stability and improved texture.
