What is PEG-40 Sorbitan Peroleate?

PEG-40 Sorbitan Peroleate is a nonionic surfactant from the ethoxylated sorbitan ester group. It forms by esterifying sorbitol-derived sorbitan with peroleic acid from perilla seed oil, then adding about 40 ethylene oxide molecules for water solubility. This structure features a hydrophobic fatty chain and hydrophilic polyether tail. Primarily used in rinse-off cleansers like shampoos and body washes, plus leave-on emulsions such as lotions and creams. It works by decreasing interfacial tension, allowing oil droplets to disperse evenly in water for stable, creamy textures. As a solubilizer, it disperses fragrances and oils into aqueous bases, creating clear micellar waters and toners. Its surfactant action supports mild foaming and dirt removal while leaving a soft after-feel.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.
Solubilizing agent
Helps incorporate oils and fragrance into water-based formulas by forming micro-solutions, enabling clear sprays, toners, and micellar products.

Benefits

Delivers a softening effect during cleansing routines

Supports stable, smooth-textured emulsions in lotions

Aids solubilization for clear, even fragrance distribution

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
Users of daily cleansers needing gentle foam and rinse
People sensitive to ethoxylated ingredients
Individuals applying lotions for consistent, non-separating formulas
Those selecting strictly PEG-free cosmetics
Those preferring water-based products with incorporated scents
Users wary of potential trace impurities in surfactants

Safety Notes

  • Considered safe for cosmetic use by regulatory bodies when formulated properly
  • EWG score of 3 indicates moderate overall concern profile
