PEG-30 Phytosterol

What is PEG-30 Phytosterol?

PEG-30 Phytosterol consists of phytosterols, natural sterols extracted from plants like soybeans or tall oil, chemically linked to a chain of 30 polyethylene glycol units. This modification imparts amphiphilic properties, allowing the ingredient to interact with both water and oil phases in formulations. Primarily used in rinse-off products such as shampoos, body washes, and facial cleansers, as well as leave-on items like conditioners and moisturizers, it functions by lowering surface tension to promote foaming and dispersion during cleansing. As an emulsifier, it forms a protective film at the oil-water interface, preventing separation and ensuring smooth, consistent product textures that enhance application and feel on the skin.

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.

Benefits

Supports stable emulsions in lotions and creams for even blending of ingredients.

Facilitates effective cleansing and foaming in shampoos and washes.

Non-comedogenic nature helps maintain clear pores in formulations.

Who It's For

Who May Benefit Who Should Avoid
Users of emulsion-based moisturizers seeking consistent textures.
Those sensitive to polyethylene glycol derivatives.
Individuals relying on foaming cleansers for daily routines.
Individuals preferring PEG-free formulations.
People with normal to oily skin using surfactant-containing products.
People with known contact allergies to plant sterols.

Safety Notes

  • Regarded as safe for cosmetic use by regulatory bodies when properly manufactured.
  • Potential for low-level impurities from processing, minimized in quality products.
