PEG-80 SORBITAN PALMITATE

What Is PEG-80 SORBITAN PALMITATE?

A polyethylene glycol sorbitan ester produced by ethoxylating sorbitan Palmitic Acid (C16) with 80 moles of ethylene oxide. This nonionic surfactant/emulsifier is highly hydrophilic (solubilizer, detergent). It is used in cosmetic formulations to blend oil and water phases, solubilize fragrances and oils, and improve product texture.

Key Skin Benefits

• + Highly hydrophilic — excellent solubilizer for oils, fragrances, and essential oils
• + Nonionic — compatible with all ingredient types (anionic, cationic, amphoteric)

Pros

• + CIR-reviewed — PEG sorbitan esters considered safe in cosmetics at typical use levels
• + Versatile highly hydrophilic — wide formulation compatibility
• + Effective at low concentrations (0.5-5%)
• + Nonionic — compatible with all surfactant and ingredient types

Cons

• − Ethoxylation process may produce trace 1,4-dioxane and ethylene oxide — requires purification
• − Fully synthetic — petroleum-derived PEG with modified natural fatty acid
• − Limited biodegradability of PEG chains
• − May be irritating at high concentrations or on compromised skin barriers
• − Some variants may be comedogenic at higher use levels
